Abstract: The present invention is intended to control the color temperature of white exhibited by a liquid crystal display device. White is produced when light waves emitted through pixels associated with three colors of red, green, and blue have maximum intensities. The amounts of light emitted through the respective pixels are controlled by differentiating the shapes of the pixel electrodes disposed at the respective pixels from one another. Thus, the color temperature of white is controlled. Otherwise, the shapes of interceptive films disposed at the respective pixels are differentiated from one another in order to control light waves emitted through the respective pixels. Thus, the color temperature of white is controlled. The interceptive film may be shaped like the pixel electrode. Otherwise, the interceptive film may be realized with an interceptive pattern other than that of the pixel electrode or one of openings bored in a black matrix.

Abstract: The present invention provides a display method realizing reduction in a moving picture blurring by forming one frame by two fields of different luminance, in which increase in an unapplied voltage due to shortening of data voltage write time is suppressed. A gate voltage is applied in a light field for a period of time which is twice as long as scan line selection time, thereby decreasing an unapplied voltage. On the other hand, a gate voltage is applied normally in a dark field for the scan line selection time, so that the case where the unapplied voltage increases is eliminated. As a result, an image with high reproducibility can be obtained.
