Abstract:
Improvement is to be achieved against poor image quality attributable to voltage drops on wirings, and the image quality especially of large image display devices is to be ameliorated. The circuit configuration comprises a scanning circuit for controlling a plurality of pixel circuits; a plurality of scanning wirings for conveying the signals of the scanning circuit to the pixel circuits; a plurality of first and second wirings for supplying image signals and power to the pixel circuits, arranged in parallel to each other and crossing said scanning wirings; and a drive circuit for supplying image signals and power to the first and second wirings; all disposed over a glass substrate, wherein the drive circuit supplies power to both first and second wirings when the light-emitting devices emit light in response to image signals.
