wherein the first light-emitting element comprises a first pixel electrode, a first organic layer, and a common electrode stacked in this order,

wherein the light-receiving element comprises a second pixel electrode, a second organic layer, and the common electrode stacked in this order,

wherein the first organic layer comprises a first light-emitting layer,

wherein the second organic layer comprises a photoelectric conversion layer,

wherein a first layer and a second layer are provided in a region between the first light-emitting element and the light-receiving element,

wherein the first layer overlaps with the second organic layer and comprises a material identical to a material of the first organic layer,

wherein the second layer overlaps with the first organic layer and comprises a material identical to a material of the second organic layer,

wherein an end portion of the first organic layer and an end portion of the first layer face each other in the region between the first light-emitting element and the light-receiving element, and

wherein an end portion of the second organic layer and an end portion of the second layer face each other in the region between the first light-emitting element and the light-receiving element.

2 . The display apparatus according to claim 1 , further comprising a second light-emitting element,

wherein the second light-emitting element comprises a third pixel electrode, a third organic layer, and the common electrode stacked in this order,

wherein the third organic layer comprises a second light-emitting layer,

wherein a third layer and a fourth layer are provided in a region between the second light-emitting element and the first light-emitting element,

wherein the third layer overlaps with the third organic layer and comprises a material identical to the material of the first organic layer,

wherein the fourth layer overlaps with the first organic layer and comprises a material identical to a material of the third organic layer,

wherein an end portion of the first organic layer and an end portion of the third layer face each other in the region between the second light-emitting element and the first light-emitting element, and

wherein an end portion of the third organic layer and an end portion of the fourth layer face each other in the region between the second light-emitting element and the first light-emitting element.

3 . The display apparatus according to claim 1 , further comprising a resin layer,

wherein the resin layer is positioned in the region between the first light-emitting element and the light-receiving element,

wherein the end portion of the first organic layer and the end portion of the first layer face each other with the resin layer therebetween, and

wherein the end portion of the second organic layer and the end portion of the second layer face each other with the resin layer therebetween.

4 . The display apparatus according to claim 1 , further comprising a first insulating layer,

wherein the first insulating layer is positioned between the first light-emitting element and the light-receiving element, and

wherein the first insulating layer is in contact with the end portion of the first organic layer, the end portion of the second organic layer, the end portion of the first layer, and the end portion of the second layer.

5 . A method for manufacturing a display apparatus, the method comprising:

a first step of forming a first pixel electrode and a second pixel electrode side by side;

a second step of forming an island-shaped first organic layer over the first pixel electrode using a first metal mask;

a third step of forming an island-shaped second organic layer over the second pixel electrode using a second metal mask;

a fourth step of dividing each of the first organic layer and the second organic layer by etching in a region between the first pixel electrode and the second pixel electrode; and

a fifth step of forming a common electrode covering the first organic layer and the second organic layer,

wherein the first organic layer comprises a light-emitting organic compound, and

wherein the second organic layer comprises a photoelectric conversion material.

6 . The method for manufacturing a display apparatus, according to claim 5 , further comprising a sixth step of forming a resin layer in a slit formed by the etching between the fourth step and the fifth step.

7 . The method for manufacturing a display apparatus, according to claim 6 ,

wherein a photosensitive organic resin is used for the resin layer.

8 . The method for manufacturing a display apparatus, according to claim 6 , further comprising a seventh step of forming a first insulating layer in contact with a side surface of the first organic layer and a side surface of the second organic layer which are exposed by the etching between the fourth step and the sixth step.

9 . The method for manufacturing a display apparatus, according to claim 8 ,

wherein a metal oxide film formed by an atomic layer deposition method is used as the first insulating layer.
