Abstract
A light-emitting device includes a light-emitting layer containing: quantum dots serving as light emitters; and dummy flakes not involved in emitting light. The quantum dots are localized. Thanks to such features, light generated from the quantum dots is diffracted in the light-emitting layer, directed in a normal direction that is a thickness direction of an array substrate, and emitted out of the light-emitting device.
