The invention discloses an array substrate, a manufacturing method thereof, a display panel and a defect repair method of the display panel, and belongs to the field of manufacturing of liquid crystal panels. The array substrate comprises a lining substrate, wherein a grid metal pattern is formed on the lining substrate; the grid metal pattern comprises a grid and a signal line; a source-drain metal pattern is formed on the lining substrate on which the grid metal pattern is formed; the source-drain metal pattern is insulated from the grid metal pattern; the source-drain metal pattern comprises a source, a drain, a data line and a repair structure; the repair structure is electrically connected with the data line; an insulating layer and a pixel electrode are formed in sequence on the lining substrate on which the source-drain metal pattern is formed; the pixel electrode is electrically connected with the source or the drain; an overlapping region exists between positive projections of the pixel electrode and the repair structure on the lining substrate. By adopting the array substrate, the manufacturing method thereof, the display panel and the defect repair method of the display panel, repair of dark spots is realized, and the problems of low product yield and high production cost caused by bright and dark spots are solved.
Description
technical field [0001] The invention relates to the field of liquid crystal panel manufacturing, in particular to an array substrate and a manufacturing method thereof, a display panel and a defect repairing method thereof. Background technique [0002] A liquid crystal display (English: Liquid Crystal Display; LCD for short) is a commonly used display device. During the production process, bright and dark point defects often appear on the LCD display panel. Bright and dark spots are a common defect in display panels, and the processing cost is extremely high, which increases the production cost. Therefore, the improvement of bright and dark spot defects has become a widely concerned issue. [0003] The improvement of bright and dark spot defects in the prior art mainly realizes the improvement of bright spots into dark spots. The specific method is: use laser (laser) to cut off the polysilicon active layer (English: Polycrystal Silicon; abbreviation: P-Si), and turn brig...
