Abstract
A data line driving circuit connected to data lines includes a bit shift unit that outputs input digital data composed of a plurality of bits for defining the brightness of pixels or bit-shifts the plurality of bits to lower levels to output them, based on a control signal, and a supply unit that supplies the output digital data of the bit shift unit to a D/A conversion unit. The D/A conversion unit supplies gray-scale signals obtained by D/A converting the output digital data of the supply unit to the data lines.
