Abstract:
1. A display device comprising: a first substrate; a second substrate; a first, a second and a third organic light emitting element provided over a surface of the first substrate and electrically connected to thin film transistors; and a fourth organic light emitting element provided over a surface of the second substrate, wherein the first substrate faces the second substrate, wherein each of the first, the second, the third and the fourth organic light emitting elements includes a first electrode, a second electrode, and a layer containing an organic compound sandwiched between the first electrode and the second electrode, wherein the first and second electrodes of at least one of the organic light emitting elements provided over the first and second substrates comprise a transparent conductive film, wherein a first light emitting region of the first organic light emitting element, a second light emitting region of the second organic light emitting element and a third light emitting region of the third organic light emitting element provided over the first substrate are at least partly overlapped with a fourth light emitting region of the fourth organic light emitting element provided over the second substrate, and wherein the first, the second, the third and the fourth organic light emitting elements are included in one pixel.
