Abstract

A substrate for an LCD display device exhibiting improved display quality through lower contact resistance and elimination of undercutting. The display switches have three electrodes, at least one of which has three metal layers, the third of which is formed by nitrating the second metal layer. The pixel electrode is electrically connected to the second metal layer through a contact hole formed through an insulation layer and the second metal layer of the switching device.

Description

technical field

[0001] The invention relates to an array substrate, a method for manufacturing the array substrate and a display device with the array substrate. More particularly, the present invention relates to an array substrate with improved display quality, a method of manufacturing the array substrate with improved display quality, and a display device with the array substrate with improved display quality. Background technique

[0002] Generally, a liquid crystal display (LCD) device includes an array substrate, a color filter substrate opposite to the array substrate, and a liquid crystal layer interposed between the array substrate and the color filter substrate. The array substrate has a plurality of pixels, and each pixel includes: a gate line providing a gate signal, a data line providing a data signal, a thin-film transistor (TFT) electrically connected to the gate line and the data line, and receiving a data signal and applying it to the liquid crystal layer. ...
