置。[Claims for Utility Model Registration] A plurality of rows of scanning signal lines, a plurality of columns of data signal lines that intersect with the scanning signal lines, a switching element connected to the scanning signal line and the data signal line at this intersection; a pixel electrode connected to a switching element; a scanning circuit that sequentially supplies scanning pulses with a predetermined pulse width to the scanning signal line; and a data drive circuit that supplies a data signal to the data signal line; In a liquid crystal display device in which the data signal is supplied to the pixel electrode through the switching element when a scanning pulse applied to the element is in an on state, the data signal is input to the switching element located farthest from the scanning circuit. The data signal is set such that the data signal rises after the scan pulse has almost completely risen to the on state, and the data signal has fallen after the scan pulse has almost completely fallen to the off state. A liquid crystal display device characterized by comprising a control circuit that sets supply timing.
