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 translation: 本发明旨在控制由液晶显示装置展示的白色色温。 当通过与红色，绿色和蓝色三种颜色相关联的像素发射的光波具有最大强度时，产生白色。 通过将设置在各个像素处的像素电极的形状彼此相差来控制通过各个像素发射的光的量。 因此，白色的色温被控制。 否则，设置在各个像素处的截取膜的形状彼此不同，以便控制通过各个像素发射的光波。 因此，白色的色温被控制。 截取膜可以像像素电极那样成形。 否则，可以以除了像素电极之外的截止图案或黑矩阵中钻孔的一个之外的截取图案来实现截取膜。
