Liquid crystal display

A liquid crystal display comprising:

• a display configured to drive pixel circuits to display an image of one frame according to a gradation to be displayed, by combination of sub-frames each of which has a display period shorter than one frame period, wherein the pixel circuits are arranged on cross-points where each of column data lines intersects row scanning lines;
• a horizontal scanning unit configured to sequentially output to the column data lines by one horizontal scanning period unit, data associated with the image of one frame;
• a vertical scanning unit configured to output a row selection signal for sequentially selecting the row scanning lines one by one by one horizontal scanning period unit;
• and
• a trigger pulse generator configured to output a trigger pulse to the pixel circuits in common,
• wherein each of the pixel circuits comprises:
• a first hold unit including a first transistor, a first inverter and a second inverter,
• the first transistor having a gate terminal connected to one of the row scanning lines and a drain terminal connected to one of the column data lines, and
• the first and second inverters to which a higher driving voltage and a lower driving voltage arbitrarily set between a power-supply voltage and a ground voltage are supplied, and to which the power-supply voltage and the ground voltage are supplied as a well potential, and
• the first hold unit configured to selectively hold the higher or lower driving voltage according to the row selection signal output from the vertical scanning unit via the one row scanning line and a logical value of the data output from the horizontal scanning unit via the one column data line;
• a second hold unit configured to selectively hold the higher or lower driving voltage held in the first hold unit;
• a transfer control unit configured to transfer to the second hold unit, the higher or lower driving voltage held in the first hold unit according to the trigger pulse;
• and
• a pixel unit configured to drive a liquid crystal according to a potential difference between the higher or lower driving voltage held in the second hold unit and a voltage supplied to a common electrode thereof,
• wherein the first inverter has an input terminal connected to an output terminal of the second inverter and a source terminal of the first transistor, and an output terminal connected to an input terminal of the second inverter and the transfer control unit, and
• and wherein the second inverter has the input terminal connected to the output terminal of the first inverter and the transfer control unit, and the output terminal connected to the input terminal of the first inverter and the source terminal of the first transistor.
