    Abstract: A high-definition and high-resolution display apparatus is provided. The display apparatus includes a first light-emitting device, a second light-emitting device, an insulating layer, and a first sidewall. 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. Each of an end portion of the first pixel electrode and an end portion of the second pixel electrode is covered with the insulating layer. The first sidewall is positioned over the insulating layer and covers a side surface of the first light-emitting layer.

    Abstract: A display device having both a touch detection function and a function of capturing an image of a shape of a fingerprint or a vein is provided. The display device includes a first light-emitting element, a second light-emitting element, a light-receiving element, and a light-blocking layer. The first light-emitting element and the light-receiving element are arranged on the same plane. The light-blocking layer is provided above the first light-emitting element and the light-receiving element. The second light-emitting element is provided above the light-blocking layer. The first light-emitting element has a function of emitting visible light upward. The second light-emitting element has a function of emitting invisible light upward. The light-receiving element is a photoelectric conversion element having sensitivity to visible light and invisible light. In a plan view, the light-blocking layer includes a portion positioned between the first light-emitting element and the light-receiving element. In the plan view, the second light-emitting element overlaps with the light-blocking layer and is positioned inside the outline of the light-blocking layer.
