Abstract
The disclosure includes bus wiring constituted by wiring lines; a gradation voltage generation circuit that generates M gradation voltages representing brightness levels with M gradations, and applies the M gradation voltages to an intermediate portion on M wiring lines belonging to the bus wiring; a plurality of decoders, each of which receives M gradation voltages via the M wiring lines and selects one of the M gradation voltages according to the pixel data pieces to output the selected gradation voltage; a plurality of output amplifiers that individually amplifies the voltages output from the plurality of decoders and generates the amplified voltages as the plurality of pixel drive voltages; and first and second inter-gradation short circuits that short-circuit one ends of each of the M wiring lines and the other ends of each of the M wiring lines according to a load signal for capturing the pixel data pieces.
