Abstract
A display device includes a plurality of light-emitting layers each capable of emitting light in a reference direction orthogonal to a light-emitting surface, and a light-blocking portion capable of blocking part of light traveling from the light-emitting surface in directions inclined with respect to the reference direction. The plurality of light-emitting layers include a first light-emitting layer capable of emitting light with a first peak wavelength and a second light-emitting layer capable of emitting light with a second peak wavelength that is longer than the first peak wavelength. The first light-emitting layer has, compared with the second light-emitting layer, a large ratio of the part of light that can be blocked by the light-blocking portion to light traveling in at least one certain direction out of the inclined directions.
