Abstract
The present invention provides a display device. The display device comprises a first substrate having formed thereon a pixel section (12) in which a plurality of pixels (11) are arranged in a matrix form and driving systems (13, 14) for driving to write pixel signals to the pixel section (12), a second substrate arranged to face the first substrate, and a liquid crystal layer held between these substrates. As control systems (23, 24, 25) for controlling the driving systems (13, 14) are mounted as semiconductor chips on the first substrate in a COG method, reducing the thickness of the whole device is realized.
