Patent ID: 8384699

Claim:
A semiconductor device comprising: a first substrate comprising a first conductive adhesive layer; a pixel portion over the first substrate; a second substrate over the pixel portion; a driving circuit over the first substrate; a first layer comprising a first circuit over the first substrate; a second layer comprising a second circuit over the first substrate; and a flexible printed circuit over the first substrate, wherein the first layer and the second layer are overlapped each other, wherein the first layer comprises a first wiring in a first opening in the first layer, wherein the second layer comprises a second wiring and an auxiliary wiring in an opening in the second layer, wherein the first layer is adhered with the second layer by a second conductive adhesive layer so that the first wiring is connected with the second wiring via the auxiliary wiring, wherein the second circuit is connected with the first circuit via the first wire, the auxiliary wiring and the second wiring, wherein the second circuit is electrically connected with the first conductive adhesive layer via a bump connected with the second wiring, and wherein at least one of the first layer and the second layer is electrically connected with the flexible printed circuit.
