Patent ID: 7483109

Claim:
A display device comprising a quadrangular display panel having a plurality of display pixels arrayed in a matrix, and a plurality of scan lines and a plurality of signal lines each adapted to select the plurality of the display pixels, a scan line driver element, having a scan line driver circuit formed on a dielectric substrate and made up of thin film transistors and adapted to receive signals and a power supply voltage from an external circuit and supply said power supply voltage to said scan lines in response to the supplied signals, wherein said scan line driver element is mounted on a peripheral rim along one side of said display panel outside the display pixel region, a signal line driver element, having a signal line driver circuit made up of mono crystal silicon transistors and adapted to receive signals and a power supply voltage from said external circuit and supply said power supply voltage to said signal lines in response to the supplied signals, wherein said signal line driver element is mounted on the peripheral rim along another side adjoining said one side of said display panel outside the display pixel region in an arrangement in which said signal line driver element is mounted on a film substrate, and FPC cable in which wirings are formed to supply said signals and power supply voltage from said external circuit to said scan line driver element and said display panel and adapted to supply signals and the power supply voltage to said scan line driver element and said display panel through said wirings.
