Abstract:
1. A display device comprising: a single crystal semiconductor substrate; a pixel portion comprising a light emitting element and a transistor electrically connected to the light emitting element; a substrate facing the single crystal semiconductor substrate with the light emitting element interposed therebetween; and a wiring over the single crystal semiconductor substrate, wherein the light emitting element comprising a first electrode, an EL layer over the first electrode and a second electrode over the EL layer, wherein the EL layer is in contact with the first electrode in a light emitting region of the light emitting element, wherein a thickness of the first electrode in a region except the light emitting region is larger than a thickness of the first electrode in the light emitting region, wherein the transistor comprises a channel formation region in the single crystal semiconductor substrate, wherein the wiring is electrically connected to the pixel portion, and wherein the EL layer is capable of emitting white light.
