Abstract

The invention discloses an array substrate, a liquid crystal display panel and a manufacturing method of the array substrate. The array substrate comprises a first metal layer provided with a first metal wire, an insulating layer covering the first metal layer and a second metal layer covering the insulating layer. The second metal layer comprises a second metal wire. The second metal wire overlaps with the first metal wire through the insulating layer to form a grid. The second metal wire is provided with reinforcing parts at four corners of the part overlapping with the first metal wire. The reinforcing parts respectively attach to the lateral sides and the upper surface of the first metal wire through the insulating layer. The array substrate has the advantages that the strength of the climbing parts of the second metal wire is increased by the reinforcing parts, the climbing parts of the second metal wire cannot be easily disconnected, vertical wire disconnection occurrence rate is lowered, and product yield is increased favorably.

Description

technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to an array substrate and a liquid crystal display panel with the array substrate, and also relates to a method for manufacturing the array substrate. Background technique [0002] Since TFT-LCD (Thin Film Transistor-Liquid Crystal Display, thin film transistor-liquid crystal display) has the advantages of small size, low power consumption, and no radiation, it has been developed rapidly in recent years. [0003] As an important part of TFT-LCD, the liquid crystal display panel includes a color filter (Color filter, CF), an array substrate, and a liquid crystal disposed between the two, wherein the array substrate includes a gate line metal layer and the The metal layer of the data line arranged overlapping the metal layer of the gate line, the gate line arranged in parallel is arranged on the metal layer of the gate line, the data line arranged in parallel is...
