Abstract
A light-emitting element includes a first electrode, an organic layer with a light-emitting layer made of organic light-emitting material, a half-transmitting/reflecting film, a resistance layer, and a second electrode, which are sequentially laminated on top of the other. The first electrode reflects light from the light-emitting layer, the second electrode transmits light from the light-emitting layer. The half-transmitting/reflecting film includes a first half-transmitting/reflecting film and a second half-transmitting/reflecting film which are laminated in this order from a side of the organic layer. Also, the half-transmitting/reflecting film on the organic layer has an average thickness of 1 nm to 6 nm.
