Abstract:
A display apparatus with high display quality is provided. The display apparatus includes a first light-emitting device, a second light-emitting device, a first coloring layer, a second coloring layer, and a first insulating layer. The first light-emitting device includes a first pixel electrode over the first insulating layer, a first EL layer over the first pixel electrode, and a common electrode over the first EL layer. The second light-emitting device includes a second pixel electrode over the first insulating layer, a second EL layer over the second pixel electrode, and the common electrode over the second EL layer. The first coloring layer is provided to overlap with the first light-emitting device. The second coloring layer is provided to overlap with the second light-emitting device. The first coloring layer and the second coloring layer transmit light of different wavelength ranges. The first insulating layer includes a depressed portion between the first pixel electrode and the second pixel electrode. A third EL layer is provided in the depressed portion of the first insulating layer. The first EL layer, the second EL layer, and the third EL layer contain the same material. The sum of the thickness of the first pixel electrode and the depth of the depressed portion is larger than the thickness of the third EL layer.
