Liquid crystal display device, array substrate thereof and manufacturing method

Abstract

The invention discloses a liquid crystal display device, an array substrate thereof, and a manufacturing method for the array substrate. The liquid crystal display device comprises the array substrate, a color filter substrate and a liquid crystal layer sandwiched between the array substrate and the color filter substrate. A voltage application circuit, a reference circuit and a first pad are arranged on the array substrate, wherein the reference circuit is adjacent to the voltage application circuit; and materials and manufacturing processes for the reference circuit and the voltage application circuit are the same. If the reference circuit is judged to have a defect, the voltage application circuit can be judged to probably have a defect by taking the defect of the reference circuit as a reference, and the array substrate can be specially controlled and repaired to reduce a defective rate.

Description

technical field [0001] The present invention relates to the technical field of LCD (Liquid Crystal Display, liquid crystal display), in particular to a liquid crystal display device, an array substrate and a method for manufacturing the array substrate. Background technique [0002] The prior art liquid crystal display generally includes: an array substrate, a color filter substrate, and a liquid crystal layer interposed between the array substrate and the color filter substrate. One of the liquid crystal display devices is provided with test pads, auxiliary circuits and semiconductor array circuits on the array substrate. The auxiliary circuit includes a pressurization circuit, and the pressurization circuit is respectively connected with the semiconductor array circuit and the test pad. [0003] PSVA (Polymer Stabilized Vertical Alignment, Polymer Stabilized Vertical Alignment technology) process is: cutting the edge of the color filter substrate to expose the test pad in...

Problems solved by technology

[0004] However, if the voltage circuit is abnormal during this process, and the electric field cannot be generated between the color filter substrate and the array substrate, the liquid crystal molecules cannot be normally deflected and aligned, resulting in poor display or slow response rate of liquid crystal molecules in the produced liquid crystal display device. status

In addition, the PSVA process is an irreversible process, and there is no way to repair the LCD device in the subsequent process, resulting in serious waste
