Problems solved by technology

[0007] However, the known liquid crystal displays that combine wide viewing angle technology and transflective technology all add a plurality of bumps in the transmissive area and reflective area of ​​the color filter array substrate, so that it is necessary to add a lithography and Etching (photo-etching process, PEP) process steps not only complicate the structure, increase the production cost, but also relatively increase the alignment error

Embodiment Construction

[0045] Please refer to image 3 , image 3 It is a schematic diagram of the first embodiment of the color filter array substrate 50 according to the present invention. image 3 As shown, the color filter array substrate 50 of this embodiment is applied in a semi-transmissive and semi-reflective wide viewing angle liquid crystal display 42, and together with another transparent upper substrate 52 and a liquid crystal layer 70 constitute the transflective and semi-reflective Type wide viewing angle liquid crystal display 42. The color filter array substrate 50 includes a transparent substrate 54 , and a plurality of pixels 600 are disposed on the transparent substrate 54 and located between the transparent upper substrate 52 and the transparent substrate 54 . To simplify the description, only one pixel 600 is taken as an example, wherein each pixel 600 may include a plurality of sub-pixels 60S, 62S, 64S, respectively provided with color filter layers of different colors, such ...

Abstract

The invention provides a colored filter array substrate, which is applied to a semi-transmission and semi-reflection wide-viewing-angle liquid crystal display. The colored filter array substrate comprises a transparent substrate and a plurality of sub-pixels, wherein each sub-pixel comprises a reflection region, a transmission region, a colored filter layer and a transparent electrode, wherein the colored filter layer is provided with at least one groove. In the invention, the wide viewing angle technology of the semi-transmission and semi-reflection liquid crystal display is realized by using a groove of the colored filter layer, so that the structure is simplified, the manufacturing process is shortened, and the yield of a liquid crystal display panel is increased effectively.

Description

[0001] The present invention is a divisional application of the Chinese invention patent application with the application number 200910119354.7, the application date is March 25, 2009, and the invention name is "color filter array substrate". technical field [0002] The invention provides a color filter array substrate, especially a color filter array substrate used for a transflective and semi-reflective liquid crystal display with a wide viewing angle. Background technique [0003] According to different sources of illumination light, liquid crystal displays can be divided into three types: transmissive mode, reflective mode, and transflective mode. The transmissive liquid crystal display has a backlight for generating light, and the light generated by the backlight passes through the liquid crystal display panel to allow users to watch the display screen of the liquid crystal display. The reflective liquid crystal display is provided with a reflective layer. When the ref...
