Color film substrate, display panel and preparing method of color film substrate

Abstract

The invention discloses a color film substrate, a display panel and a preparing method of the color film substrate. The color film substrate comprises a first glass substrate body and a retaining wallformed on the surface, facing an array substrate, of the first glass substrate body. The retaining wall is of a structure protruding from the surface of the first glass substrate body. The retainingwall is located in a non-display area. The invention further provides the corresponding display panel and the preparing method of the color film substrate. By means of the color film substrate, the display panel and the preparing method of the color film substrate, the alignment film retaining wall is designed through the CF side glass substrate body, the boundary of a CF side alignment film can be freely controlled, and it is avoided that vapor enters the panel through the CF side alignment film and corrodes a circuit.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a color filter substrate, a display panel and a method for preparing the color filter substrate. Background technique [0002] Liquid crystal display (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal digital assistants, digital cameras, notebooks, etc. Various consumer electronic products such as computers and desktop computers have become the mainstream of display devices. [0003] In an active liquid crystal display, each sub-pixel has a thin film transistor (TFT), its gate (Gate) is connected to the horizontal scanning line, the drain (Drain) is connected to the vertical data line, and the source (Source) is connected to the pixel electrodes. Applying sufficient voltage on the horizontal scanning line will turn on all the TFTs on the horizontal scanning line. At this time, the pixel electrodes on the ho...

Problems solved by technology

[0006] However, if the COA and POA processes are used and the injection process is used to manufacture the PI (polyimide) alignment film, the coating accuracy of the PI alignment film on the CF substrate cannot be controlled. The uneven thickness of the PI film on the CF substrate leads to uneven images. Therefore, under normal circumstances, the PI alignment film on the CF substrate will exceed the coating position of the sealant (Sealant) used as the frame glue, and completely cover the CF substrate.

This also causes water vapor to easily enter the panel through the PI alignment film on the CF substrate, resulting in shortened life of the components inside the panel or corrosion of the internal lines of the panel, making the panel display abnormal
