Patent ID: 7567330

Claim:
An electro-optical device comprising: a first substrate; a second substrate including a display region and an extending region extending from the display region, the display region overlapping the first substrate in plan view and the extending region being in a non-overlapping condition with the first substrate in plan view; a third substrate connected to the extending region of the second substrate; a plurality of first wiring lines each extending over the extending region in an extending direction; a first insulation layer over the plurality of first wiring lines; a plurality of second wiring lines each extending over the first insulation layer in the extending direction, each of the plurality of second wiring lines being in a non-overlapping condition with each of the plurality of first wiring lines in the extending region in plan view; a second insulation layer over the plurality of second wiring lines; a plurality of first contact holes through the first insulation layer and the second insulation layer, the plurality of first contact holes connecting respective ones of the first wiring lines with the third substrate; and a plurality of second contact holes through the second insulation layer, the plurality of second contact holes connecting respective ones of the second wiring lines with the third substrate, the plurality of second contact holes each being shifted away from each of the plurality of first contact holes in the extending direction and in a direction perpendicular to the extending direction.
