Patent ID: 8184075

Claim:
An active matrix display device comprising: driving means provided on a substrate; an insulating film stacked on the substrate; and light-emitting elements arranged in a matrix on the insulating film, and each of the light-emitting elements includes an light-emitting layer between its upper and lower electrodes; the active matrix display device being driven by the driving means provided for each of the light-emitting elements, the active matrix display device also including a first wiring required to cause the light-emitting element to emit light, and a second wiring disposed in an underlying layer of the first wiring via the insulating film, the second wiring also required to cause the light-emitting element to emit light, wherein the first or second wiring is branched into a plurality of wirings at an intersection between the two wirings, wherein, the first wiring is a signal line disposed for each column, scan line disposed for each row or power line disposed for each row of the light-emitting elements arranged in the matrix, and the second wiring is a signal connection line adapted to connect split segments of the signal line split where the signal line intersects the scan and power lines.
