Abstract

The invention discloses a liquid crystal display device and a color optical filter thereof. The color optical filter comprises a plurality of filter units and black matrix layers. The filter units are distributed into an array at intervals. Each filter unit corresponds to one subpixel unit of the liquid crystal display device. The black matrix layers are formed between the filter units. The cross section of the black matrix layer between every two adjacent filter units comprises a wide upper portion and a narrow lower portion.

Description

【Technical field】 [0001] The present invention relates to a thin film transistor liquid crystal display, in particular to a thin film transistor liquid crystal display device with low impedance signal line and its signal line. 【Background technique】 [0002] Liquid crystal displays have the advantages of low power consumption, thinness, and high resolution, so they are currently the mainstream of displays. With the development and progress of liquid crystal display technology, people put forward higher requirements for the display quality of liquid crystal displays, such as high color gamut, low color shift, and narrow frame. [0003] The viewing angle characteristic is an important criterion for judging the display quality of an LCD display. There are many factors that affect the viewing angle characteristic, such as different liquid crystal display modes (such as TN mode, VA mode, and IPS mode), pixel structure, and process accuracy. [0004] figure 1 A partial cross-sec...
