An optical element is provided includes an optical layer having a flat incident surface on which light is incident and a wavelength-selective reflective layer disposed in the optical layer. Of light incident on the incident surface at an incident angle (, ), the optical element selectively directionally reflects light in at least one specific wavelength range in at least one direction other than a specular reflection direction (, +180) while transmitting light in at least one wavelength range other than the specific wavelength range, and is transparent to light in at least one wavelength range other than the specific wavelength range.


Provided is a transparent conductive film that suppresses deterioration of display characteristics due to reduced contrast and that has excellent long-term conductivity, even when exposed to harsh conditions. The transparent conductive film includes one or more metal nanowire bodies and a colored compound adsorbed onto the metal nanowire bodies. The colored compound includes a first dye that includes a macrocyclic -conjugated moiety and a moiety having a functional group that exhibits adsorptivity with respect to a constituent metal of the metal nanowire bodies.


The present invention relates to a color conversion sheet, a light-emitting device, an image display device assembly and green-emitting phosphor particles.

[Solution] Provided is a water purification agent suitable for use in an automated purification treatment device, when a wastewater purification treatment using a plant-derived water purification agent is performed with the automated purification treatment device. The water purification agent is a granulated product containing a mixture of a plant powder and a polymer coagulant.


An underfill material enabling voidless packaging and excellent solder bonding properties, and a method for manufacturing a semiconductor device using the same are provided. An underfill material is used which contains an epoxy resin and a curing agent, and a time for a reaction rate to reach 20% at 240 C. calculated by Ozawa method using a differential scanning calorimeter is 2.0 sec or less and a time for the reaction rate to reach 60% is 3.0 sec or more. This enables voidless packaging and excellent solder connection properties.
