Abstract:
A data line drive circuit includes a plurality of output circuits and a plurality of switch portions. The plurality of output circuits outputs voltages corresponding to grayscale voltages with respect to display data. The plurality of switch portions becomes an ON-state in response to a line output signal and connects the plurality of output circuits and a plurality of data lines, respectively. ON-resistance values of at least part of the plurality of switch portions vary in the ON-state.
