Abstract:
An electronic 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 having an opposed electrode provided over the second substrate, the second substrate being opposed to the pixel matrix region of the first substrate; a third substrate comprising an insulator provided over the first substrate outside the pixel matrix region, the third substrate having a long side in X-direction and having a short side in Y-direction; a drive circuit for driving the pixel matrix region, the drive circuit being provided over the third substrate; a plurality of first lead wirings provided outside the pixel matrix region over the third substrate and connected to the drive circuit, each of the first lead wirings having a portion thereof extending in the Y-direction; a plurality of second lead wirings provided over the first substrate and extending from the pixel matrix region toward the third substrate, each of the second lead wirings having a portion thereof extending in the Y-direction; second electrode pads arranged at end portions of the plurality of second lead wirings; first electrode pads having an area smaller than that of the second electrode pads and arranged at end portions of the plurality of first 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 in the Y-direction.
