Patent ID: 7548226

Claim:
A liquid crystal display in which pixels are driven by active matrix drive, the display comprising: a liquid crystal display screen composed of pixels arranged in a matrix, the liquid crystal display screen being divided into a first screen and a second screen; gate driver to output a gate pulse to gate lines connected to gates of thin film transistors in the pixels, the gate driver being divided into a first gate driver to output a gate pulse to gate lines connected to gates of thin film transistors in pixels in the first screen and a second gate driver to output a gate pulse to gate lines connected to gates of thin film transistors in pixels in the second screen; source driver to output a source voltage to source lines connected to sources of the thin film transistors in the pixels, the source driver being divided into a first source driver to output a source voltage to source lines connected to sources of the thin film transistors in the pixels in the first screen and a second source driver to output a source voltage to source lines connected to sources of the thin film transistors in the pixels in the second screen; interframe polarity controller to control to alternately repeat, for each frame, a first reversal pattern where a polarity of liquid crystal in the pixels is subjected to a horizontal reversal once every m lines, m being 2 or a greater positive integer and a second reversal pattern where polarity reversal of lines in the first reversal pattern is shifted by n lines, n being a positive integer equal to a half or less of m.
