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 substrate, a first light-emitting element, a second light-emitting element, a light-receiving element, a light-blocking layer, a first resin layer, and a second resin layer. The first light-emitting element and the light-receiving element are arranged over the first substrate, and the first resin layer is provided over the first light-emitting element and the light-receiving element. The light-blocking layer is provided over the first resin layer, and the second light-emitting element is provided over the light-blocking layer. The second resin layer is provided over the second light-emitting layer. The first light-emitting element emits visible light upward, and the second light-emitting element emits 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, and the second light-emitting element overlaps with the light-blocking layer and is positioned inside the outline of the light-blocking layer.
