Abstract
A light-emitting device emits light in a first direction and also emits light in a second direction opposite to the first direction. The light-emitting device includes a first light-emitting layer configured to emit light of a first color, and a second light-emitting layer configured to emit light of a second color different from the first color. The first light-emitting layer and the second light-emitting layer overlap each other as viewed from the first direction. The light-emitting device reduces a difference in tinge between emission light in the first direction and emission light in the second direction.
