Abstract

A higher-definition or higher-resolution display apparatus is provided. The display apparatus includes a first light-emitting device, a second light-emitting device, a first insulating layer, a first coloring layer, and a second coloring layer. The first light-emitting device includes a first pixel electrode, a first light-emitting layer over the first pixel electrode, and a common electrode over the first light-emitting layer. The second light-emitting device includes a second pixel electrode, a second light-emitting layer over the second pixel electrode, and the common electrode over the second light-emitting layer. The first insulating layer covers side surfaces of the first pixel electrode, the second pixel electrode, the first light-emitting layer, and the second light-emitting layer. The first coloring layer is placed to overlap with the first light-emitting device. The second coloring layer is placed to overlap with the second light-emitting device. The first light-emitting device and the second light-emitting device have a function of emitting white light. The first coloring layer and the second coloring layer have a function of transmitting visible light of different colors.
