Patent ID: 6900873

Claim:
A display device comprising: a first substrate having a pixel matrix region; a switching thin film transistor provided over the first substrate in the pixel matrix region; a pixel electrode connected to the switching thin film transistor and provided over the first substrate in the pixel matrix region; a second substrate comprising an insulator provided over the first substrate outside the pixel matrix region; a drive circuit for driving the pixel matrix region, the drive circuit provided over the second substrate; a plurality of first lead wirings provided outside the pixel matrix region over the second substrate and connected to the drive circuit; a plurality of second lead wirings provided over the first substrate and extending from the pixel matrix region toward the second substrate; first electrode pads arranged at end portions of the plurality of first lead wirings: second electrode pads having an area smaller than that of the first electrode pads and arranged at end portions of the plurality of second lead wirings; and a conductive member provided over the first substrate and connecting at least one of the first electrode pads with corresponding one of the second electrode pads, wherein contiguous ones of the first electrode pads with each other are shifted periodically in a direction of a side of the second substrate.
