Patent ID: 8487840

Claim:
A display device comprising: an element portion comprising: a first light shielding film over a substrate; an interlayer insulating film over the first light shielding film; a second light shielding film over the interlayer insulating film; an element over the second light shielding film, the element comprising: a first electrode over the second light shielding film; an electroluminescent layer over the first electrode, the electroluminescent layer being capable of emitting light; and a second electrode over the electroluminescent layer; and a first thin film transistor electrically connected to the element, wherein the element and the first thin film transistor are provided not to be overlapped with each other, wherein the first light shielding film is provided to be overlapped with an entire portion of the first electrode, wherein the second light shielding film is provided to be overlapped with only a portion of the first electrode, the portion including an edge of the first electrode, and wherein the first light shielding film and the second light shielding film are capable of blocking the light emitted from the electroluminescent layer, a pixel portion comprising: a light-emitting element; and a second thin film transistor electrically connected to the light-emitting element.
