Embodiment Construction

[0030] In order to facilitate the understanding of the present invention, the rubbing alignment method and the liquid crystal display device will be described more comprehensively below with reference to the relevant drawings. The method of rubbing alignment and the preferred embodiment of the liquid crystal display device are given in the accompanying drawings. However, the rubbing alignment method and the liquid crystal display device can be implemented in many different forms, and are not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the method of rubbing alignment and the liquid crystal display device more thorough and comprehensive.

[0031] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element...

Abstract

The invention relates to a method of friction alignment and a liquid crystal display device. The method of friction alignment is used for friction alignment of an array substrate which comprises graphical areas and a blank area isolating the graphical areas. Each graphical area comprises a graphical area body and an integrated circuit control position next to the graphical area body. The method offriction alignment comprises the steps of: providing an array substrate and pre-arranging a conducting film layer in a blank area of the array substrate; etching the pre-arranged conducting film layer to form a pattern on the conducting film layer; placing the array substrate on a alignment table; connecting the conducting film layer of the array substrate to the ground; performing friction froma friction start point of the array substrate towards the inside of the array substrate. The conducting film layer of the array substrate is grounded in advanced, so that generation of static electricity of the conducting film layer of the array substrate in a friction process can be prevented, damage by static electricity to the array substrate during friction alignment can be prevented and the yield rate of manufacture of liquid crystal display devices can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of manufacturing liquid crystal display devices, in particular to a rubbing alignment method and a liquid crystal display device. Background technique [0002] The alignment process in the manufacturing process of liquid crystal display devices is a very critical process. It needs to be aligned on the two substrates that make up the LCD screen, that is, both the color filter substrate and the array substrate need to be aligned. The alignment process is one of the important processes that determine the performance and quality of liquid crystal displays. The alignment process includes: first coating the polyimide film on the product; then processing grooves on the polyimide film through a specific processing technology, so that the liquid crystal molecules are arranged along the direction of the grooves, and the liquid crystal molecules are given a certain degree of alignment in the outside world. The electri...
