Abstract
Buffer circuits and analogue switches are disposed closer to a display region than video busses. A timing signal generator circuit provides the buffer circuits with a timing signal. The analogue switches supply video signals from the video busses to signal lines in the display region in response to the timing signal. Parasitic capacitance coupled to the video busses is reduced so that bandwidth characteristics of the busses can be improved and a good display can be also obtained.
