Abstract

The invention discloses a display panel and a manufacturing method thereof. The display panel comprises a substrate, the substrate comprises a display area and a surrounding area surrounding the display area, and the display panel further comprises at least one layer of protective layer covering the cutting area corresponding to a cutting line of the surrounding area. The display panel has the advantages that the protective layer is arranged at the edge of the surrounding area, the protective layer can absorb laser energy and release impact force when the laser technology is used subsequentlyfor cutting, edge film layers are prevented from being heated and impacted to generate cracks spreading to the display area, and problems that the film layers of the cutting area is prone to cracks due to excessive laser intensity in the existing technology and the cracks conduct inward into the display area to affect the display are solved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a manufacturing method thereof. Background technique [0002] In the field of display, due to the organic light emitting diode (Organic Light Emitting Display, OLED) display panel has self-illumination, no backlight, high contrast, thin thickness, wide viewing angle, fast response speed, can be used for flexible panels, operating temperature Wide range and other excellent characteristics are considered to be the new application technology of the next generation of flat panel displays. At present, flexible OLED display devices have become an important development direction of display devices. [0003] In the prior art, the manufacturing process of the flexible display panel is as follows: multiple flexible display panels are formed on a large display motherboard, and then cut to form independent flexible display panels. At present, flexible OLEDs are cut by ...
