Problems solved by technology

Although the liquid crystal display panel with this structure used for the verification test can keep the array substrate with the same surface morphology as the actual product before coating the alignment film, the test signal is transmitted through the thin film transistor, and the performance of the thin film transistor will depend on the quality of the thin film transistor. Will affect the verification results of the alignment film coating process

Abstract

The invention discloses an array substrate, which is used for verifying and testing an alignment film prepared by a coating process. The array substrate includes a first metal layer, a gate insulating layer, a second metal layer, a gate insulating layer, a second a metal layer, an interlayer insulating layer, a transparent conductive layer and a first alignment film layer; a plurality of pixels are arranged in the array substrate, and each pixel includes: a common electrode line located in the first metal layer, a transparent conductive layer located in the a pixel electrode, a first via hole passing through each structural layer between the first metal layer and the transparent conductive layer, the pixel electrode is electrically connected to the common electrode line through the first via hole, so that the test signal It is transmitted to the pixel electrode through the common electrode line. The present invention also discloses a liquid crystal display panel, comprising the above-mentioned array substrate, which is used to perform a verification test on an alignment film prepared by a coating process through a lighting test.

Description

technical field [0001] The present invention relates to the technical field of displays, and in particular to an array substrate and a liquid crystal display device for verifying and testing an alignment film prepared by a coating process. Background technique [0002] With the development of liquid crystal display technology, Thin Film Transistor Liquid Crystal Display (TFT-LCD) is widely used in LCD TVs, mobile phones, computers, etc. electronic product. TFT-LCD is a passive light-emitting display device. The liquid crystal molecules themselves cannot emit light. It needs to be equipped with a backlight source. By controlling the deflection of the liquid crystal molecules, the light intensity of the backlight source can be controlled, and then through the color filter. Filtering effect, realize full-color image display and grayscale control. [0003] In the liquid crystal display panel, the alignment film with the alignment direction on the color filter substrate and the...
