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.
