Array substrate of liquid crystal display and scanning line structure of array substrate

Abstract

The invention discloses an array substrate of a liquid crystal display and a scanning line structure of the array substrate. The scanning line structure in an AA region and a non display region outside the AA region particularly comprises a first scanning line and a second scanning line which are alternately arranged in the non display region in sequence and positioned in different metal layers; a third scanning line in the AA region extends to the middle in the edge of the non display region; contact holes are formed in the first scanning line, the second scanning line and the third scanning line which are positioned on the two sides in the middle; and the first scanning line and the second scanning line are electrically connected with the third scanning line through the contact holes by transparent electrodes respectively. Through the structure, the resistance difference between adjacent wire harnesses in the dual-layer wiring process can be reduced, the width of each fan-shaped wire harness is reduced at the same time, the center and the edge in a fan section of each fan-shaped wire harness are wired in an equal-resistance way, the probability of causing horizontal stripes is reduced, and the purpose of improving the displaying effect of the whole liquid crystal display is achieved.

Description

technical field [0001] The invention relates to the field of manufacturing liquid crystal displays, in particular to an array substrate of a liquid crystal display and a scanning line structure thereof. Background technique [0002] Nowadays, in the display field, AM-LCD (Active Matrix liquid crystal display, active matrix liquid crystal display) is widely used as a mainstream product. Among them, TFT LCD (Thin Film Transistor liquid crystal display, thin film field effect transistor liquid crystal display) is a kind of AM-LCD. It has the advantages of excellent performance, large-scale production, high degree of automation, and low cost of raw materials, and will quickly become the mainstream display product in the new century. [0003] In the design of TFT LCD, the resistance design of the fanout wiring (fan wiring) area of ​​the scanning line is very important. If the wiring resistance difference between the center and the edge of the fanout is very large, the scan dela...
