Abstract
[Problem to be solved] Obtain a constitution for a data driver which does not easily affected by transistor characteristics. [Solution] A plurality of coupling capacitancesis connected to data enable lines which is equipped to at least two set potentials. A plurality of bit transistorswhich is turned on and off in accordance with the display data of a plurality of bits controls the relation of connection between a plurality of coupling capacitances and data enable lines to control the total capacitance of the said plurality of coupling capacitances. Display element operates in accordance with the voltage accumulated to the total capacitance of the said coupling capacitance according to the difference between the two set potentials equipped to the data enable line. By the operations above, a display is controlled by multi-bit display data per each pixel.
