Mask plate, array substrate and manufacturing method of array substrate

Abstract

The invention discloses a mask plate, an array substrate and a manufacturing method of the array substrate. The mask plate comprises a first patterned light-transmitting region formed on one side of the mask plate, a second patterned light-transmitting region formed inside the mask plate and located on the opposite side of the first patterned light-transmitting region, a first mark and a second mark, wherein the first mark is formed on the side, close to the center of the mask plate, of the first patterned light-transmitting region, and a first preset distance is formed between the first mark and the first patterned light-transmitting region; the second mark is formed on the side, away from the center of the mask plate, of the first patterned light-transmitting region, and a second preset distance is formed between the second mark and the first patterned light-transmitting region. When one connecting terminal area in the array substrate made from the mask plate is suspended, a gate line is covered with an insulating layer, in this way, the gate line is not likely to be corroded by vapor in air or scratched, and then reliability of the array substrate is guaranteed.

Description

technical field [0001] The present invention relates to the field of liquid crystal display technology, in particular to a mask plate, an array substrate and a manufacturing method thereof. Background technique [0002] Liquid crystal displays have the advantages of low radiation, small size, and low energy consumption. They have gradually replaced traditional cathode ray tube displays and are widely used in products such as flat-screen TVs, personal computers, and mobile display panels. [0003] For a large-size liquid crystal display panel, due to the long wiring of the array substrate, the RC time delay of the line and the large line load, it is generally necessary to use a double-sided driving method for driving. However, for the same product, in order to meet the needs of different customers, the driving methods of the liquid crystal display panel (such as signal inversion method and frame refresh rate, etc.) will be different, so different driving methods can correspon...
