Liquid crystal display panel, colour filter and manufacturing method of colour filter

Abstract

The invention discloses a liquid crystal display panel, a colour filter and a manufacturing method of the colour filter. The colour filter comprises a transparent substrate, a black matrix, a first colour filter unit, a second colour filter unit and a conducting layer, wherein the transparent substrate comprises an active area and a dummy area, the first colour filter unit in the active area is shaped like a trapezium, the second colour filter unit in the dummy area is shaped like an inverted trapezium, the part of conducting layer covering the active area part is continuous, the part of conducting layer covering the dummy area is discontinuous, the active area can conduct electricity normally, and insulation effect is formed in the dummy area. When the colour filter and a thin film transistor are assembled, even if conductive particles exist in the dummy area, no common potential abnormal condition can be caused as the conducting layer in the dummy area is discontinuous, thus abnormal short circuit can be prevented when the colour filter and the thin film transistor are assembled and product quality is further improved.

Description

technical field [0001] The invention relates to the field of electronic display, in particular to a liquid crystal display panel, a color filter and a manufacturing method thereof. Background technique [0002] In widely used LCD displays, red, green and blue (RGB) primary color filter regions are arranged in a predetermined manner to form a color filter unit. [0003] As in TFT-LCD, see figure 1 , the color filter (CF) includes a color filter unit functional area 101 (CF Active area) and a color filter unit spacer area 102 (CF Dummy area). Correspondingly, see figure 2 , the thin film transistor array (TFT Array) includes a thin film transistor functional area 103 (TFT Active area), a thin film transistor spacer area 104 (TFT Dummy area) and a curing pad 105 (curing pad). [0004] see image 3 , is a schematic diagram of the interval area after the color filter and the thin film transistor array are paired, 106 is the color filter substrate, 107 is the conductive layer...

AI Technical Summary

Problems solved by technology

[0005] In the long-term research and development work, the inventors found that if there are conductive particles 114 above the through holes 112 of the thin film transistor, the conductive layer 113 of the thin film transistor may be connected to the conductive layer 107 of the color filter, resulting in a common potential of the color filter. abnormality, or if there are relatively large conductive particles 114 in the area where there are no TFT through-holes 112, in the process of grouping, they may press through the TFT insulating layer 110, directly reach the TFT second layer 111, and then Connecting with the conductive layer 107 of the color filter will also cause abnormal common potential of the color filter
