Liquid crystal display device, active matrix type liquid crystal display device, and method of driving the same
First Claim
1. A method of driving a display device comprising:
- during a first frame, applying first image signals to a first group of pixels with a positive polarity and a second group of pixels with a negative polarity, wherein the first group of the pixels is adjacent to the second group of the pixels with a first boundary therebetween; and
during a second frame subsequent to the first frame, applying second image signals to a third group of pixels with the positive polarity and a fourth group of pixels with the negative polarity wherein the third group of the pixels is adjacent to the fourth group of the pixels with a second boundary therebetween, the second boundary being in a different position from the first boundary, wherein the third group of the pixels is partly overlapped with the first group of the pixels, and the fourth group of the pixels is partly overlapped with the first group of the pixels.

Abstract
A liquid crystal display device with no flicker and with bright excellent display is provided. A polarity pattern of a conventional frame inversion driving is one kind of display. A polarity pattern of a conventional source line inversion driving is two kinds of display, and a disclination pattern is one kind of display. On the contrary, in a circuit structure of the present invention, polarity patterns are made to have not less than four kinds, and disclination patterns are made to have not less than two kinds. By this, bright display in which flicker is not included and poor display due to disclination is improved, can be obtained.
