Problems solved by technology

[0005] Embodiments of the present invention provide a liquid crystal display substrate and a preparation method thereof, a display panel, and a display device, so as to solve the problem that in the prior art, an alignment film pattern with a corner shape cannot completely cover the corner area when the alignment liquid is applied. As a result, there is a situation of missing printing in the corner area, resulting in a technical problem of light leakage at the display edge of the display device.

Embodiment Construction

[0047] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0048] This embodiment provides a liquid crystal display substrate. The liquid crystal display substrate can be, for example, an ITO glass substrate, which can be used as a component of a liquid crystal display panel. The liquid crystal display panel can be, for example, a flat liquid crystal display panel or a 3D liquid crystal display panel. figure 2 It is a structural schematic diagram of a liquid crystal display substrate provided by an embodiment of the present invention. Such as figure 2As shown, the liqu...

Abstract

An embodiment of the present invention provides a liquid crystal display substrate, a preparation method thereof, a display panel and a display device. By setting an alignment film formed on the substrate to have a body alignment region and an extension region at a corner of the body alignment region, the extension region is a special-shaped pattern different from that of the body alignment region, the body alignment region at least covers a display region of the liquid crystal display substrate such that an alignment material at the corner of an alignment film body alignment region further diffuses and extends to the extension region and the alignment film coating the substrate can completely cover the display region of the liquid crystal display substrate, therefore, the orientation ofliquid crystal molecules injected into the display region can be controlled after the liquid crystal display substrate is subjected to cell formation, and a light leakage phenomenon can be prevented.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display substrate and a preparation method thereof, a display panel and a display device. Background technique [0002] A Liquid Crystal Display (LCD) has the advantages of a thin body, low power consumption, and clear image quality, and is widely used in display fields such as televisions, mobile terminals, and computers. Especially in 3D display technology, a liquid crystal display is used as a 3D display to display stereoscopic images different from a flat 2D display. [0003] Generally, an LCD includes a casing of a display device, a display panel inside and a backlight module. Among them, the structure of the LCD display panel is mainly composed of a thin film transistor (Thin Film Transistor, TFT) array substrate, a color filter (Color Filter, CF) substrate, and a liquid crystal layer located between the TFT array substrate and the CF substrate. The work...
