Patent number: 9703161Abstract: 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.Type: GrantFiled: January 30, 2014Date of Patent: July 11, 2017Assignees: Japan Display Inc., Panasonic Liquid Crystal Display Co., Ltd.Inventors: Ikuko Mori, Munenori Motooka, Ryutaro Oke, Kazunori Ojima, Kikuo Ono
