LIGHT-EMITTING DEVICE

摘要

A light-emission device includes a substrate and a G light-emission layer; an R light-emission layer, a B light-emission layer, and a wiring layer made of metal that are each arranged above the substrate. Each of the G light-emission layer, the R light-emission layer, and the B light-emission layer contains light-emission material. An amount of heat that the B light-emission layer generates upon light emission is greater than an amount of heat that the G light-emission layer generates upon light emission. Further, the B light-emission layer directly faces the wiring layer at a facing edge portion.

1. A light-emission device comprising:
a substrate; a first light-emission unit above the substrate, the first light-emission unit including a first light-emission layer that contains light-emission material; a second light-emission unit above the substrate, the second light-emission unit including a second light-emission layer that contains light-emission material and that is adjacent to the first light-emission layer; a third light-emission unit above the substrate, the third light-emission unit including a third light-emission layer that contains light-emission material and that is adjacent to the first light-emission layer, wherein an amount of heat that the third light-emission layer generates upon light emission is greater than each of an amount of heat that the first light-emission layer generates upon light emission and an amount of heat that the second light-emission layer generates upon light emission; and a wiring layer above the substrate and adjacent to the third light-emission layer, the wiring layer being made of metal and comprising a line structure or a matrix structure, wherein the third light-emission layer has a longer facing edge portion than each of the first light-emission layer and the second light-emission layer, a facing edge portion of a given light-emission layer being an edge portion directly facing the wiring layer, or the third light-emission layer has a larger facing surface portion than each of the first light-emission layer and the second light-emission layer, a facing surface portion of a given light-emission layer being a surface portion directly facing the wiring layer.
