Problems solved by technology

[0019] In addition, regarding color filters, they are formed of R (red), G (green), and B (blue), but even with the techniques proposed in Patent Document 4 and Patent Document 5, it is impossible to independently design the reason for the transmission mode and the reflection mode. White balance composed of RGB
[0020] Also, even with a structure in which pinholes are provided in the color filter in the reflective mode area, it is not possible to independently set the white balance composed of RGB in the transmissive mode and reflective mode.

Abstract

The semi-transparent type LCD device of the present invention is formed by laminating an optical reflective film, coloring layer 3, upper passivation layer, transparent electrode and alignment film on a glass substrate, and comprises a light-transmission part 7 whose transmitted areas to the optical reflective film are different with respective coloring layer 3. Also, a recess groove part 8 is formed in the reflective region of each coloring layer 3. By the above constitution, white balance formed by the RGB of transmission mode and reflective mode can be independently set up. Through the white balance adjustment proceeded in this way, a semi-transparent type LCD device with high quality and high performance can be provided.

Description

technical field [0001] The present invention relates to a transflective color liquid crystal display device having functions of both reflective mode and transmissive mode, and particularly relates to a transflective color liquid crystal display device capable of adjusting white balance. Background technique [0002] In recent years, liquid crystal display devices have been used in small or medium portable information terminals and notebook computers, and large and high-definition monitors. In particular, for devices that are used both outdoors and indoors, such as portable information terminals, in an environment where the external light is very strong, as an illumination part of a display device, actively use external light (reflection mode), and in an environment with weak external light , a transflective liquid crystal display device using a backlight (transmission mode) is used as a mainstream. [0003] According to this transflective color liquid crystal display device...
