Patent ID: 8237169

Claim:
A display device comprising: a substrate; at least a first pixel and a second pixel arranged adjacent to each other over the substrate, each of the first pixel and the second pixel comprising: a first thin film transistor and a second thin film transistor; a capacitor wherein a first terminal of the capacitor is electrically connected to a first terminal of the first thin film transistor and a gate of the second thin film transistor; and a light-emitting element electrically connected to a first terminal of the second thin film transistor, the light-emitting element comprising a light-emitting layer comprising an organic material, a gate wiring extending along a direction, and electrically connected to a gate of the first thin film transistor in the first pixel and the second pixel; a first wiring extending across the gate wiring, and electrically connected to a second terminal of the first thin film transistor in the first pixel; a second wiring extending across the gate wiring, and electrically connected to a second terminal of the first thin film transistor in the second pixel; and a third wiring extending in parallel with the gate wiring, and electrically connected to a second terminal of the second thin film transistor in the first pixel and the second pixel, wherein each of the first terminal and the second terminal of the first thin film transistor and the first terminal and the second terminal of the second thin film transistor is triple layered film in which aluminum is sandwiched by titanium, and wherein the third wiring is configured to supply a current with the light-emitting element in the first pixel and the second pixel.
