Patent number: 7471358Abstract: In order to make a boundary inconspicuous, which is located between an image area which displays an image by translucent pixels and a dummy area which always displays a white color by reflection pixels, a size ratio of transparent areas in color filters of the reflection pixels with respect to reflection areas therein is made larger than a size ratio of transparent areas in color filters of the translucent pixels with respect to reflection areas therein. In such a way, brightness of the display is balanced by adjusting quantities of transmission light through the transparent areas of the reflection pixels with respect to quantities of reflection light generated unexpectedly on transmission areas of the translucent pixels. Then, degrees of whiteness in the translucent pixels and the reflection pixels are approximated to each other.Type: GrantFiled: November 2, 2006Date of Patent: December 30, 2008Assignee: Toshiba Matsushita Display Technology Co., Ltd.Inventors: Keiji Tago, Hiroshi Tabatake, Hiroyuki Kimura, Tetsuya Iizuka
