1. A display device comprising:
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,
wherein the first light-emitting element and the light-receiving element are arranged over the first substrate,
wherein the first resin layer is provided over the first light-emitting element and the light-receiving element,
wherein the light-blocking layer is provided over the first resin layer,
wherein the second light-emitting element is provided over the light-blocking layer,
wherein the second resin layer is provided over the second light-emitting element,
wherein the first light-emitting element is configured to emit visible light upward,
wherein the second light-emitting element is configured to emit invisible light upward,
wherein the light-receiving element is a photoelectric conversion element having sensitivity to the visible light and the invisible light,
wherein in a plan view, the light-blocking layer comprises a portion positioned between the first light-emitting element and the light-receiving element, and
wherein in a plan view, the second light-emitting element overlaps with the light-blocking layer and is positioned inside an outline of the light-blocking layer.
