Defect repairing method of flexible display panel

A defect repairing method of a flexible display panel, comprising:

• providing a transparent substrate, the transparent substrate comprising a first surface and a second surface opposite to each other;
• forming a flexible substrate on the first surface;
• forming an array substrate layer on a surface of the flexible substrate, wherein the array substrate layer comprises a display area and a peripheral area;
• irradiating the display area with a patterned laser on the second surface;
• and
• annealing the transparent substrate on which the array substrate layer and the flexible substrate are formed,
• wherein the step of irradiating the display area with a patterned laser on the second surface comprises, providing a mask having a pattern and attaching the mask to the second surface and irradiating the mask by an ultraviolet laser;
• separating the flexible substrate not blocked by the mask from the transparent substrate, and adhering the flexible substrate covered by the mask and the transparent substrate to each other, and
• wherein the pattern of the mask makes a position on the transparent substrate not obscured by the mask directly opposite to the display area, the position blocked by the mask is directly opposite to the peripheral area.
