Patent ID: 8547315

Claim:
A semiconductor device comprising: a first pixel over a first substrate, wherein the first pixel comprises: a first electrode over the first substrate; an insulating layer over the first electrode; an electroluminescent layer over the first electrode and the insulating layer; and a second electrode over the electroluminescent layer and the insulating layer; a second pixel over the first substrate; a third pixel over the first substrate; a fourth pixel over the first substrate; a first power supply line electrically connected to the first pixel and the second pixel; a second power supply line electrically connected to the first power supply line; a third power supply line electrically connected to the third pixel and the fourth pixel and electrically connected to the second power supply line, wherein the second power supply line intersects with the first power supply line and the third power supply line; a first line electrically connected to the first pixel and the third pixel; a second line electrically connected to the second pixel and the fourth pixel; a gate signal line driver circuit, wherein a first terminal of the gate signal line driver circuit is electrically connected to the first line and the second line; and a second substrate fixed to the first substrate with a sealing material without interposing the insulating layer between the sealing material and the first substrate.
