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.
