A light guide plate having light-emitting-side unit optical shapes arranged on a light emitting surface in a direction perpendicular to a light guide direction and a thickness direction of the light guide plate. The optical shape extends in the light guide direction and has a groove shape recessed in the light emitting surface, and a bottom of the groove is formed on a surface which is concave toward the back surface side. Inclined surfaces which are inclined from an edge portion toward the bottom side are formed in two end portions of the concave surface in an arrangement direction. When a width of the optical shape in the arrangement direction is W21, a maximum inclination angle of the inclined surface relative to the light emitting surface satisfies 2045, and a radius of curvature r of the concave surface satisfies rW21/(4sin ).


A substrate for suspension comprises a metallic substrate, an insulating layer formed on the metallic substrate, a conductor layer formed on the insulating layer, and a cover layer covering the conductor layer. The insulating layer and the cover layer are formed from different materials, whose coefficients of hygroscopic expansion are in the range between 310^(6)/% RH and 3010^(6)/% RH. The difference between the coefficients of hygroscopic expansion of the two materials is 510^(6)/% RH or less.

A method for producing a multiple-surface imposition vapor deposition mask that enhances definition and reduces weight even when a size is increased. Each of multiple masks in an open space in a frame is configured by a metal mask having a slit, and a resin mask that is positioned on a front surface of the metal mask and has openings corresponding to a pattern to be produced by vapor deposition arranged by lengthwise and crosswise in a plurality of rows. In formation of the plurality of masks, after each of the metal masks and a resin film material for producing the resin mask are attached to the frame, the resin film material is processed, and the openings corresponding to the pattern to be produced by vapor deposition are formed in a plurality of rows lengthwise and crosswise, whereby the multiple-surface imposition vapor deposition mask of the above described configuration is produced.

A packaging material for a cell including a layered film in which at least a base-material layer, an adhesive layer, a metallic layer, and a sealant layer are layered in the stated order. The packaging material for a cell including a layered body in which at least a base-material layer, an adhesive layer, a metallic layer, and a sealant layer are layered in the stated order, wherein the packaging material for a cell can be imparted with highly exceptional moldability, and dramatically less prone to pinholing and cracking during molding by using, as the metallic layer, an aluminum foil having 0.2% yield strength of 58-121 N/mm^(2 )when a tensile test is performed in the direction parallel to the rolling direction.

A thermal transfer image-receiving sheet which does not cause printing failure while being provided with tear-off lines. The sheet includes a dye-receiving layer on one side of a backing sheet, a tear-off line provided crossing the sheet along a width direction of the sheet and roller contact areas configured to contact a transport roller of a printer provided on opposite sides in the width direction. In each of the roller contact areas on the opposite sides, the tear-off line is not parallel to the width direction of the thermal transfer image-receiving sheet in an area occupying half or more of the roller contact area in the width direction, and when that segment of the tear-off line which is not parallel to the width direction of the thermal transfer image-receiving sheet has one or more bends in the roller contact area, all the bends are bent at obtuse angles.


A color filter forming substrate used in a multifunctional terminal is provided which has a frame disposed surrounding respective colored layers for a color filter and having a non-display area formed by the frame portion all around a boundary between the display area and the frame, and specifically has a transparent substrate as a base material; and, on one side of the base material, colored layers of respective colors for a color filter disposed in a display area and a frame portion comprising a light-shielding colored layer disposed as a region not for display around a periphery of the region for display. The color filter forming substrate is used for a display device.


A through-electrode substrate includes a base including a first surface and a second surface mutually opposing each other, and a through-electrode arranged in a through-hole passing through the second surface from the first surface of the base, wherein the through-electrode includes an first end surface of the first surface side and an second end surface of the second surface side exposed from the base in the first surface and the second surface, and a periphery edge of one or both of the first end surface of the first surface side and the second end surface of the second surface side is covered by a part of the base.


A vapor deposition mask capable of correctly performing confirmation of whether a shape pattern of openings formed in a resin mask is normal or similar confirmation while satisfying both high definition and lightweight, a vapor deposition mask preparation body for obtaining the vapor deposition mask, a frame-equipped vapor deposition mask including the vapor deposition mask, and a method for producing an organic semiconductor element using the frame-equipped vapor deposition mask. The aforementioned problem is solved by using, in a vapor deposition mask including a metal mask in which a slit is formed and a resin mask in which an opening corresponding to a pattern to be produced by vapor deposition is formed at a position overlapping with the slit, the metal mask and the resin mask being stacked, the resin mask which has about 40% or less of light ray transmittance at a wavelength of about 550 nm.

The purpose of the first invention is to provide a packaging material for batteries, which has excellent resistance to electrolyte solution. A packaging material for batteries, which is composed of a laminate that sequentially comprises at least a base layer, an adhesive layer, a metal foil layer and a sealant layer in this order. This packaging material for batteries is able to have excellent resistance to electrolyte solution by disposing an acid-reactive resin layer containing an acid curable resin between the adhesive layer and the metal foil layer and/or between the metal foil layer and the sealant layer.
