Display devices, display modules and electronic devices

Abstract

A display device with light detection function 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 located between the first substrate and the second substrate. The light-receiving element includes a first pixel electrode on the first substrate, an active layer on the first pixel electrode, and a common electrode on the active layer. The light-emitting element includes a second pixel electrode on the first substrate, a first light-emitting layer on the second pixel electrode, and a common electrode on the first light-emitting layer. The resin layer and the light-shielding layer are each located between the common electrode and the second substrate. The resin layer includes a portion overlapping the light-emitting element. The light-shielding layer includes a portion located between the common electrode and the resin layer. The resin layer includes an opening overlapping the light-receiving element or is configured as an island. At least a portion of the light passing through the second substrate is incident on the light-receiving element without passing through the resin layer.
