Abstract
In a display device which mounts drive circuits and a display control circuit on a substrate which constitutes a display panel, signal lines can be arranged on the substrate which constitutes the display panel without making the signal lines intersect each other. A plurality of drive circuits and a display control circuit are mounted on a peripheral portion of one long side of a first substrate. A printed circuit board is connected to one long side of the first substrate. Each drive circuit mounts, on a surface thereof facing the first substrate, a group of power source voltage input terminals to which a power source voltage is supplied, a group of gray-scale reference voltage input terminals to which a gray-scale reference voltage is supplied, and a group of gray-scale reference voltage output terminals which sends gray-scale reference voltages.
