Patent ID: 7309959

Claim:
A light-emitting device, comprising: a first substrate; a second substrate mounted along a first side of the first substrate; a first electrode; a second electrode; an effective area in which a plurality of unit circuits are formed, the unit circuits having (i) light-emitting elements including light-emitting layers interposed between the first and second electrodes, and (ii) switching elements that drive the light-emitting elements; power source lines connected to the first electrode outside of the effective area, via effective area power source lines arranged in the effective area; electrode wiring lines formed along three sides of the first substrate not including the first side of the first substrate, the electrode wiring lines being connected to the second electrode across the three sides of the first substrate not including the first side of the first substrate, and the power source lines being arranged in a position in which the power source lines and the electrode wiring lines do not intersect each other in plan view.
