Abstract
A high-resolution display device is provided. The display device includes first and second light-emitting devices, first and second coloring layers, and first, second, and third insulators; the first coloring layer is positioned to overlap with the first light-emitting device; the second coloring layer is positioned 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; the first light-emitting device includes a first conductive layer and a first light-emitting layer over the first conductive layer; the second light-emitting device includes a second conductive layer and a second light-emitting layer over the second conductive layer; the first insulator is in contact with at least part of a side surface of the first light-emitting device; the second insulator is in contact with at least part of a side surface of the second light-emitting device; the first insulator and the second insulator are positioned over the third insulator; and the third insulator is positioned to cover an end portion of the first conductive layer and an end portion of the second conductive layer.
