Filed: 2003-11-12
Abstract: <P>PROBLEM TO BE SOLVED: To improve the brightness of a display image in a transmission display mode without increasing the luminance of a back light.  <P>SOLUTION: On a reflecting layer, an R, G, or B color layer is formed for each sub-pixel G. Also, in part of the area of an opening formed in the reflecting layer on the internal face of a lower substrate, an R, G, or B color layer is formed for each sub-pixel G. Thus, a color filter substrate in which the opening that corresponds to a transmission part which includes an area where the color layers are formed and a transparent area where the color layers are not formed is produced. In a liquid crystal display device having the color filter substrate, when transmission display takes places, illuminating light from the back light is transmitted through the area where the color layers are formed and the transparent area in the opening. Accordingly, the illuminating light transmitted through the color layers exhibits a prescribed hue, whereas the illuminating light transmitted through the transparent area reaches an observer while keeping bright. Thus, the brightness of the color display image in the transmission display mode can be improved without increasing the luminance of the back light.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
