a light-receiving device comprising:

a first pixel electrode;

an active layer over the first pixel electrode; and

a common electrode over the active layer;

a light-emitting device comprising:

a second pixel electrode;

a light-emitting layer over the second pixel electrode;

an electron-transport layer over the light-emitting layer; and

the common electrode over the electron-transport layer;

a partition covering an edge of the first pixel electrode and an edge of the second pixel electrode; and

a light-blocking layer between the light-receiving device and the light-emitting device,

wherein the light-receiving device and the light-emitting device are adjacent to each other,

wherein the partition is in contact with the first pixel electrode and the second pixel electrode,

wherein the light-blocking layer is interposed between the partition and the common electrode,

wherein the electron-transport layer comprises a first region and a second region,

wherein each of the first region and the second region comprises an electron-transport material and a first substance,

wherein the first region has a different concentration of the first substance from the second region, and
