Abstract

The present application discloses a display panel and a manufacturing method thereof. The display panel includes an array substrate and a color filter substrate disposed opposite to each other. The array substrate includes: a substrate and a transistor array layer arranged on the substrate, wherein the The transistor array layer includes: a first metal layer arranged on the substrate, the first metal layer includes a grid; a second metal layer arranged above the first metal layer, the second metal layer Including source, drain and metal wiring; and the repair part, which is arranged at least on both sides of the metal wiring, and together with the metal wiring to form a signal wire; compared with the prior art, the present application improves the The display unevenness caused by the etching of metal traces improves the yield rate of the display panel.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel and a manufacturing method thereof. Background technique [0002] Low temperature polysilicon (LTPS) thin film transistor liquid crystal display is different from the traditional amorphous silicon thin film transistor liquid crystal display, its electron mobility can reach more than 200cm2 / V-sec, which can effectively reduce the size of thin film transistor devices area, so as to increase the aperture ratio, and reduce the overall power consumption while increasing the brightness of the display. In addition, the higher electron mobility can integrate part of the driving circuit on the glass substrate, reducing the driving IC (integrated circuit, integrated circuit), and can also greatly improve the reliability of the liquid crystal display panel, thereby greatly reducing the manufacturing cost of the panel. ; Therefore, LTPS thin film transistor liquid...
