Abstract

A high-definition or high-resolution display apparatus is provided. In the display apparatus, a first light-emitting device includes a first pixel electrode, a first light-emitting layer, and a common electrode. A second light-emitting device includes a second pixel electrode, a second light-emitting layer, and the common electrode. End portions of the first and second pixel electrodes are covered with a first insulating layer. A second insulating layer covers side surfaces of the first and second light-emitting layers. A first color conversion layer overlaps the first light-emitting device. A second color conversion layer overlaps the second light-emitting device. The first and second light-emitting devices each have a function of emitting blue light. The first and second color conversion layers each have a function of converting light.
