Patent ID: 8188941

Claim:
A pixel circuit, comprising: a signal line; a drive transistor; a light emitting element; and at least one power source line wired so as to intersect perpendicularly said signal line; wherein said drive transistor is connected between said power source line and a predetermined electrode of said light emitting element, and any one of wirings intersecting perpendicularly one another is wired so as not to overlap a light emitting region of said light emitting element in a direction of lamination of layers, wherein said drive transistor comprising: a gate electrode formed in a first wiring layer; a channel formation region; a gate insulating film formed between said gate electrode and said channel formation region; and a first electrode and a second electrode formed so as to sandwich said channel formation region between them; said power source line includes a second wiring layer formed so as to be connected to said first electrode of said drive transistor through a contact formed in an insulating film, and a third wiring layer formed so as to be connected to said second wiring layer through a contact formed in an interlayer film, and said light emitting region of said light emitting element is formed in an upper layer of said third wiring layer in the lamination direction of the layers.
