摘要:
In a liquid crystal display panel including a plurality of scanning lines, a scanning line drive circuit which supplies a scanning voltage to the plurality of scanning lines, and a counter voltage supply circuit which supplies a counter voltage to a counter electrode of each pixel, the counter voltage supply circuit supplies a voltage which is obtained by multiplying a voltage detected from the counter electrode by correction coefficients corresponding to the plurality of respective scanning lines to the counter electrodes. The present invention provides a liquid crystal panel which can perform favorable display by preventing crosstalk attributed to coupling noises to the counter electrodes generated by AC driving of a video voltage.
