Patent ID: 8149188

Claim:
An active matrix-type EL display device comprising: a plurality of power source lines arranged in parallel with one another on a predetermined wiring layer; a plurality of signal lines arranged in parallel with one another on a wiring layer, which is different from the wiring layer on which the power source lines are arranged, so as to be orthogonal to the power source lines; a plurality of pixel circuits each including an EL element and one or more thin-film transistors, the plurality of pixel circuits being arranged side by side in an extending direction of the power source line and an extending direction of the signal line; a bypass line arranged on at least a part of a portion obtained by removing a planar position of the signal line from a planar position of the power source line in the wiring layer on which the signal lines are also arranged; and a contact establishing electric connection between the power source line and the bypass line.
