Abstract

A display device having a function of sensing light is provided. The display device includes a first substrate, a second substrate, a light-receiving element, a light-emitting element, a resin layer, and a light shielding layer. The light-receiving element, the light-emitting element, the resin layer, and the light shielding layer are each positioned between the first substrate and the second substrate. The light-receiving element includes a first pixel electrode over the first substrate, an active layer over the first pixel electrode, and a common electrode over the active layer. The light-emitting element includes a second pixel electrode over the first substrate, a first light-emitting layer over the second pixel electrode, and the common electrode over the first light-emitting layer. The resin layer and the light shielding layer are each positioned between the common electrode and the second substrate. The resin layer includes a portion overlapping with the light-emitting element. The light shielding layer includes a portion positioned between the common electrode and the resin layer. The resin layer includes a portion overlapping with the light-receiving element or is provided in an island shape. At least part of light passing through the second substrate enters the light-receiving element without through the resin layer.
