Abstract

The invention provides a defect correction method of an active matrix substrate. The method comprises the broken line detection process, whether or not a broken line exists in first gate lines and second gate lines is detected, if it is detected that the first gate lines have a broken line, the portions, beyond the broken first gate line and the portions beyond the second gate lines adjacent to the broken first gate line are cut along all second source lines which are arranged on two sides of a pixel electrode corresponding to the broken line portion of the first gate lines, source gate line repairing part forming processes of source gate line repairing parts which have the overlapped part of the first gate lines with the broken line and the second gate lines are formed respectively, amongthe second gate lines adjacent to the first gate lines with the broken line, the portions beyond all the second gate lines which are arranged along two sides of the pixel electrode corresponding to the broken portion are cut, and a gate line repairing part forming process of the gate line repairing parts which have the overlapped parts of all the second gate lines and a connecting process for connection are formed.

Description

technical field [0001] The present application relates to the technical field of liquid crystal display, in particular to a method for correcting defects of an active matrix substrate and a method for manufacturing a display device. Background technique [0002] The operation mode of the flat panel display is to control each pixel (pixel) arranged in an array by two sets of addressing lines perpendicular to each other, so as to achieve the purpose of display. In various display control modes, the gate line and the source line are most commonly used to turn on or off the corresponding switch components, so that the signal transmitted by each gate line can be written into the pixel, thereby changing The state of the corresponding pixel, and achieve the purpose of controlling the display screen. [0003] Figure 8 is a plan view showing one pixel of a conventional active matrix substrate 120 . The active matrix substrate 120 includes: a plurality of pixel electrodes 112 arran...
