Abstract

A high-resolution display apparatus is provided. The display apparatus includes a first to a fourth subpixels continuously lined up in this order, where the first and second subpixels emit light of a first color and the third and fourth subpixels emit light of a second color. The first color and the second color are different from each other. The first subpixel includes a first light-emitting device and a first coloring layer overlapping with the first light-emitting device; the second subpixel includes a second light-emitting device and the first coloring layer overlapping with the second light-emitting device; the third subpixel includes a third light-emitting device and a second coloring layer overlapping with the third light-emitting device; and the fourth subpixel includes a fourth light-emitting device and the second coloring layer overlapping with the fourth light-emitting device. The first to fourth light-emitting devices emit light of one color and are driven independently. Light transmitted through the first coloring layer and light transmitted through the second coloring layer exhibit different colors from each other.
