An apparatus for inspecting an edge portion of a substrate can inspect a defect or a chamfered width on an edge portion of a substrate. First and second right-angled prisms are disposed above and below the edge portion such that inclined surfaces thereof are directed toward the upper surface and lower surface of the edge portion. A lighting part irradiates the edge portion of the substrate with light. A photographing part is disposed adjacent to the edge portion. The photographing part takes an image of the upper surface of the edge portion from light that has passed through the first right-angled prism, an image of the lower surface of the edge portion from light that has passed through the second right-angled prism, and an image of an end surface of the edge portion.

An organic light-emitting device (OLED) which exhibits superior light extraction efficiency due to an extraction structure for dipole light generated from an organic light-emitting layer. The OLED includes a first glass substrate, a first electrode disposed on the first glass substrate, an organic light-emitting layer disposed on the first electrode, a second electrode disposed on the organic light-emitting layer, and a second glass substrate disposed on the second electrode. The second electrode has a composite electrode structure including a first transparent electrode layer and a second transparent electrode layer stacked on each other, the refractive index of the second transparent electrode layer being higher than the refractive index of the first transparent electrode layer.

A box for carrying substrates that includes a box body having an upper opening, walls and a bottom, the walls and the bottom defining therein a substrate-receiving space, and a box cover having sidewalls and a covering section so as to cover and close the upper opening of the box body. The box cover is made of a transparent material which allows the substrate-receiving space inside the box body to be seen. The substrates which are used for displays can be carried and kept in the box.

Optical films, and organic light-emitting display apparatuses employing the same, include a high refractive index pattern layer including a first surface and a second surface facing each other, wherein the first surface includes a pattern having a plurality of grooves. The plurality of grooves each have a curved surface and a depth greater than a width thereof. The high refractive index pattern layer is formed of a material having a refractive index greater than 1. The optical films, and the organic light-emitting display apparatuses, further include a low refractive index pattern layer formed of a material having a refractive index smaller than the refractive index of the material constituting the high refractive index pattern layer. The low refractive index pattern layer includes a filling material for filling the plurality of grooves.
