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: (Object) To prevent the chromaticity from changing due to the gradation in a display system for improving the blurring in an animated image where one frame is formed of two fields having different brightness. (Means for Achieving Object) According to a driving method for improving the properties of an animated image by dividing one frame into a bright field having high brightness and a dark field having low brightness where an image is displayed in the case where the gradation of the image is 190 or greater, a change in the chromaticity is great in the dark field. In order to solve this problem, the gradation properties for blue are corrected only in the dark field. The gradation properties of one color which is greatly effective on the chromaticity are changed only for the necessary gradation, and therefore, the chromaticity properties can be improved while preventing the gradation-brightness properties from being affected.
