Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0020] like image 3 As shown, a liquid crystal display device includes an array substrate, and the array substrate includes a plurality of thin film transistors 4, a scanning line 1 connected to the gates of the thin film transistors 4, a data line 2 connected to the sources of the thin film transistors 4, and the data lines 2 The width of the junction 3 of the data line 2 and the scan line 1 is greater than the width of the rest of the data line 2. Further, the widening width of the data line 2 on both sides of the junction 3 is equal. During the exposure and etching process, the intensity received by both sides of the data line 2 is equal, so the width of the widening is kept equal. After the exposure and etching process, the width of the data line 2 is uniform, and there will be no local narrowing or even disconnection.

Abstract

An array substrate and liquid crystal display device, the liquid crystal display device comprising the array substrate, and the array substrate comprising a scan line (1) and a data line (2). The width of the data line (2) at the intersection of the data line (2) and the scan line (1) is greater than the width of the remaining part of the data line (2). Also provided is an array substrate manufacturing method, comprising the step of setting a width parameter for the data line (2) in the process of forming the data line (2) so that the width of the data line (2) at the intersection of the data line (2) and the scan line (1) is greater than the width of the remaining part of the data line (2). The array substrate is of simple technique and low cost, and increases the first pass yield of the liquid crystal display device without adding extra process steps.

Description

technical field [0001] The present invention relates to the field of liquid crystal display, and more specifically, relates to an array substrate, a liquid crystal display device, and a manufacturing method of the array substrate. Background technique [0002] Existing array substrates are generally manufactured by etching process, and scanning lines and data lines are successively etched on the transparent substrate in layers, such as figure 1 , 2 As shown, the array substrate of the liquid crystal display device includes a plurality of thin film transistors (TFTs), and a thin film transistor includes a substrate, a gate and a source, the gate is connected to the scan line, and the source is connected to the data line. In the existing array substrate, the line width of the data lines will become smaller or even broken after the wet etching process, resulting in vertical broken lines or vertical line defects, which affects the yield rate.
