Patent ID: 7202597

Claim:
A display device obtained by bonding a pixel element substrate having a plurality of pixel elements arranged thereon to a driving circuit board having a driving circuit for the plurality of pixel elements, wherein the driving circuit board includes connecting terminals connected to the driving circuit for the plurality of pixel elements on the surface of the driving circuit board facing the pixel element substrate, wherein the pixel element substrate comprises: a plurality of pixel electrodes formed on a transmissive substrate, the plurality of pixel elements being formed on the plurality of pixel electrodes such that respective ends of the pixel elements are adjacent to each other; common electrode wiring lines for commonly connecting the other respective ends of the plurality of pixel elements to each other; bank regions for separating the pixel elements from each other to define individual pixel element regions; and a plurality of individual electrode wiring lines for connecting the plurality of connecting terminals of the driving circuit board to the corresponding pixel electrodes of the plurality of pixel elements via through-holes formed in the bank regions.
