Embodiment Construction

[0026] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0027] Figure 4 It is a schematic plan view of the first embodiment of the signal line of the present invention. Such as Figure 4 As shown, the signal line in this embodiment includes a first part 11 and a second part 12. The second part 12 is located on both sides of the first part 11. A groove 100 is formed on the second part. In this embodiment, the groove 100 is formed on the entire second portion 12 such that the height of the second portion 12 is lower than the first portion 11 . The depth of the groove 100 is smaller than the height of the second portion.

[0028] Since the height of the second part is lower than that of the first part, the insulating layer (gate insulating layer and / or passivation layer) formed on the signal line will also form a "convex" structure, and the friction roller passes through t...

Abstract

The invention discloses an array substrate of a liquid crystal display device, and a signal wire and a manufacturing method thereof. The signal wire comprises a first part and a second part, wherein the second part is positioned on two sides of the first part; the second part is not higher than the first part; and at least one groove is formed in the second part. The invention also discloses an array substrate with the signal wire and a manufacturing method of the signal wire. The signal wire with a convex cross section is formed by forming a groove on the signal wire; and when a friction roller passes on the signal wire, the friction can be uniform, thereby solving the problem of unfavorable friction caused by excessive height of the signal wire.

Description

technical field [0001] The invention relates to an array substrate of a liquid crystal display, a signal line and a manufacturing method thereof, in particular to an array substrate of a liquid crystal display, a signal line and a manufacturing method thereof capable of improving poor friction caused by excessive signal lines. Background technique [0002] The liquid crystal display is composed of a liquid crystal panel, a polarizing plate and a backlight module, wherein the backlight module provides flat light to the liquid crystal panel, and the liquid crystal panel is composed of an array substrate, a color film substrate and a liquid crystal layer. [0003] The liquid crystal layer is obtained by injecting liquid crystal between the array substrate and the color filter substrate. Before the injection, it is necessary to form an alignment film on the array substrate and the color filter substrate respectively, align the color filter substrate and the array substrate, and i...
