Problems solved by technology

When the color filter substrate 21 or the TFT array substrate 22 is under pressure, the spacer 23 will slide outward due to the pressure, causing light leakage from the liquid crystal display panel 20
In order to prevent light leakage from being seen, the existing method is to increase the shading area of ​​the black matrix (BM) around the spacer 23, but the increase of the shading area of ​​the black matrix will reduce the aperture ratio of the pixel

Abstract

A TFT array substrate comprises a plurality of grid lines, a plurality of data lines and a plurality of pixel units. The grid lines and the data lines are arranged in a crossed mode, and the pixel units are defined by the grid lines and the data lines. Each pixel unit comprises a thin film transistor and a pixel electrode, the TFT array substrate is further provided with a flat layer and a blocking layer, the pixel units are covered with the flat layer, and the blocking layer is arranged on the flat layer and comprises a blocking part. The blocking part is located above the thin film transistors, and the blocking part is used for stopping a photo spacer between the TFT array substrate and a color film substrate from moving. The TFT array substrate can stop the photo spacer from moving, the stability of the photo spacer is improved under the condition of not reducing the aperture opening ratio, and meanwhile the bad phenomena of light leakage and the like are avoided. The invention further relates to a liquid crystal display panel and a display device.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a TFT array substrate, a liquid crystal display panel and a display device. Background technique [0002] With the development of science and technology, thin and light, power-saving information products have flooded our lives, and displays have played a very important role in it. Whether it is a mobile phone, a personal digital assistant or a notebook computer, etc., display devices are required As a platform for man-machine communication. The main component of the display device for image display is a liquid crystal display panel. [0003] figure 1 It is a partial cross-sectional structural schematic diagram of an existing liquid crystal display panel. Such as figure 1 As shown, the liquid crystal display panel 20 includes a color filter substrate 21 and a TFT array substrate 22, the color filter substrate 21 and the TFT array substrate 22 are arranged in pai...
