Abstract

The invention discloses a protection membrane and a manufacturing method, a flexible panel, a display device and a manufacturing method thereof, relating to the technical field of display and aiming to ensure stress stability and bending properties of a flexible substrate. The protection membrane is pasted to the flexible substrate, and the flexible substrate comprises a horizontal area and at least one bending area. The protection membrane is characterized by comprising a protection membrane body and at least one through hole, wherein the through hole is formed in the protection membrane; each bending area at least corresponds to one through hole; and when the protection membrane is pasted to the flexible substrate, the orthographic projection of the through hole on the flexible substratecorresponds to the bending area. The flexible panel comprises the protection membrane disclosed by the technical scheme of the invention. The protection membrane and the manufacturing method thereof,the flexible panel and the manufacturing method thereof, and the display device disclosed by the invention are applied to flexible display.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a protective film and a manufacturing method thereof, a flexible panel, a display device and a manufacturing method thereof. Background technique [0002] Such as figure 1 As shown, in the manufacturing process of the flexible display, generally a protective film 2 is pasted on the back of the flexible substrate 1 to protect the flexible substrate 1 . After attaching the protective film, the flexible substrate 1 needs to be bent to perform a modularization process on the flexible substrate, which increases the bending radius of the flexible substrate, which is not conducive to the full-screen flexible display. [0003] In order to overcome the above problems, such as figure 1 As shown, after the flexible substrate is bent, it is necessary to use laser to remove the part of the protective film 2 located in the bending area to form the through hole 20, so as to reduce the bendin...
