Array substrate, liquid crystal display panel and manufacturing methods thereof

Abstract

The invention relates to an array substrate, a liquid crystal display panel and two manufacturing methods thereof. The array substrate comprises a propping body arranged on a grid scanning line, and when the array substrate and a color film substrate are arranged in a cassette-to-cassette manner, the propping body respectively props against a columnar spacer on the color film substrate so as to stop the malposition and the movement of the two substrates. The liquid crystal display panel utilizes the array substrate of the invention, each columnar spacer is arranged corresponding to the grid scanning line of the array substrate, and at least a part of columnar spacers respectively and mutually prop against each propping body. The two manufacturing methods can be respectively used for manufacturing the array substrate and the liquid crystal display panel in the invention, and forming the propping body on the grid scanning line while an active layer graphic and a source / drain electrode are formed. The invention avoids the malposition when the color film substrate and the array substrate are under stress, improves the precise alignment of the liquid crystal display panel and is beneficial to guaranteeing the excellent quality of the picture by a technical scheme that the propping body is arranged on the array substrate to block the columnar spacer.

Description

technical field [0001] The invention relates to liquid crystal display technology, in particular to an array substrate, a liquid crystal panel and a manufacturing method thereof. Background technique [0002] Liquid Crystal Display (hereinafter referred to as: LCD), especially Thin-Film Transistor Liquid Crystal Display (hereinafter referred to as: TFT-LCD) is a flat-panel display device commonly used now, and its display function is the main component It's an LCD panel. [0003] A liquid crystal panel is generally formed by boxing a color filter substrate and an array substrate, and liquid crystal molecules are encapsulated in the gap between the boxed color filter substrate and the array substrate to form a liquid crystal layer. Among them, taking TFT-LCD as an example, figure 1 is a schematic top view structure diagram of an array substrate in the prior art, figure 2 It is a schematic diagram of a longitudinal partial cross-sectional structure of a liquid crystal pane...

AI Technical Summary

Problems solved by technology

However, the existing columnar spacer application technology still has certain defects: when the liquid crystal panel is used vertically, it will inevitably be affected by its own gravity or the impact of the outside world. The direction of the plane provides support for the color filter substrate and the array substrate, and has no pasting function. Therefore, when the liquid crystal panel is subjected to force in the direction of the plane where it is located, the columnar spacer will also be stressed in the horizontal or vertical direction. The array substrate and the color filter substrate will be misaligned or slipped, and the resulting inaccurate alignment will cause the misalignment of the black matrix and TFT to cause light leakage or uneven cell thickness, which will affect the picture quality of the LCD.
