Problems solved by technology

However, PFA needs to open holes. In order to minimize the height difference, the thickness of PFA should reach 4-6μm or even thicker. In this case, the opening of the holes is easy to cause incomplete development and lead to poor ITO contact holes, which will affect the quality of the LCD panel.

Abstract

The invention provides a liquid crystal display panel used for display. The liquid crystal display panel comprises an array substrate and a color film substrate. The portion between the array substrate and the color film substrate is filled with liquid crystals. The array substrate comprises a color resistor layer. The color resistor layer comprises multiple color resistors arranged in a matrix mode. A stacking region formed by stacking of two color resistors with different colors is arranged between every two adjacent color resistors. The color film substrate comprises a main gap light resistor arranged corresponding to the stacking regions. The color film substrate further comprises a protective layer. The protective layer is arranged on the surface, facing the array substrate, of the color film substrate and covers the surface, not provided with the main gap light resistor, of the color film substrate. The liquid crystal display panel has the advantages that peripheral light shielding performance is improved, the segment difference between a main BPS and an auxiliary BPS is increased, redundancy of LC margin is improved, the risk of incomplete development of a polymer film is avoided, the number of photomasks is not increased, and loss of the color gamut quality is not needed.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a liquid crystal display panel. Background technique [0002] In order to increase the aperture ratio of the LCD panel and reduce the production cost, the current array substrate adopts COA (color filter on array) technology, that is, the RGB color resistance on the color filter substrate (CF) side is moved to the array substrate, and only the black matrix layer is reserved on the color filter substrate side. (BM), ITO electrode (VAtype) and PS. A further step is to remove the BM film layer and replace the traditional BM with RB color resist stacking. see figure 1 As shown, the transmission spectrum of red light (R) and blue light (B) is quite different, resulting in a significant decrease in the light that passes through the overlapping of two layers of color resists, thereby achieving the effect of BM. At the same time, the original transparent photoresist gap (PS) is r...
