Abstract

The invention provides an array substrate which comprises a base layer. A plurality of signal lines parallel to one another and test wires are arranged in the base layer, the test wires correspond to the signal lines respectively and are parallel to one another, the test wires and the signal lines are located on different surface layers of the base layer and are crossed, one end of each test wire is connected with the corresponding signal line, the other end of each test wire is connected with a test point, and each signal line is connected with an earth point. The invention further provides a manufacturing method of the array substrate.

Description

technical field [0001] The invention relates to liquid crystal display technology, in particular to an array substrate and a manufacturing method. Background technique [0002] A Liquid Crystal Display (LCD for short) displays various images by controlling the light transmittance of liquid crystal pixels arranged in an array on a liquid crystal panel. Generally, a driver chip for driving a liquid crystal panel is crimped on a thin film transistor liquid crystal display (Thin Film Transistor Liquid Crystal Display; TFT LCD for short) panel. Among them, the array substrate forms a plurality of signal lines in the manufacturing process, and before cutting the array substrate to form a TFT array substrate or installing a driving circuit module on the liquid crystal display panel, it is necessary to conduct electrical tests on the signals of the array substrate, etc., to detect failures. For an array substrate that works normally, a common detection method is to set a test line ...
