LIQUID CRYSTAL DISPLAY DEVICE

摘要

A liquid crystal display device includes image signal lines, a plurality of pixel circuits that is connected to the image signal lines, an image signal line driving circuit that is connected to the image signal lines, and sequentially outputs an image signal, a gate line driving circuit that supplies a scanning signal. A period in which the gate line driving circuit supplies a scanning signal to any pixel circuit is a first period in which the image signal is output to the pixel circuit when a polarity of the image signal in a previous frame is different from the polarity in the present frame, and the first period and a second period in which the image signal of a different polarity is supplied before the first period when the polarity in the previous frame is identical with the polarity in the present frame.

1. A liquid crystal display device, comprising:
image signal lines; a plurality of pixel circuits that is connected to the image signal lines; an image signal line driving circuit that is connected to the image signal lines, and sequentially outputs an image signal indicative of a display gray level of the plurality of pixel circuits; a plurality of gate lines that is connected to the respective pixel circuits; and a gate line driving circuit that supplies a scanning signal for storing the image signal in the pixel circuits connected to the gate lines, to the respective gate lines, wherein, in case that a polarity of the image signal to be supplied to one of the plurality of pixel circuits in a previous frame is different from a polarity of the image signal to be supplied to the one pixel circuit in a present frame, the gate line driving circuit supplies the scanning signal to the one pixel circuit in a first period in which the image signal is supplied to the one pixel circuit in the present frame, and wherein, in case that the polarity of the image signal to be supplied to one of the plurality of pixel circuits in the previous frame is identical with the polarity of the image signal to be supplied to the one pixel circuit in the present frame, the gate line driving circuit supplies the scanning signal to the one pixel circuit in the first period and a second period in which the image signal of a different polarity is supplied to another pixel circuit before the first period.
