Abstract

The invention discloses a flexible display device and a manufacturing method thereof. The flexible display device comprises a flexible display panel, a photosensitive ink layer arranged on the light emitting side of the flexible display panel, and a first protection layer arranged on the side, away from the flexible display panel, of the photosensitive ink layer, wherein the flexible display panel is provided with a display area and a non-display area adjacent to the display area; the photosensitive ink layer is located in the non-display area; the first protection layer is located in the display area, and at least one side of the first protection layer extends to the non-display area to be overlapped with the photosensitive ink layer; and the photosensitive ink layer changes color under the irradiation of light in a preset wavelength range, and the first protection layer can absorb light in the preset wavelength range. According to the flexible display device, missing pasting of a CPF layer can be effectively avoided, so product yield is improved, the influence of ultraviolet rays on a luminescent material can be reduced, and the service life of the flexible display device is prolonged.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a flexible display device and a manufacturing method thereof. Background technique [0002] With the development of display technology, more and more mobile phone brands have begun to launch folding mobile phones. By folding, the 8-inch OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) flexible display screen can be turned into a portable display of about 6 inches. size. Larger-sized display screens can not only provide users with a larger visual experience, but also impose strict requirements on flexible and foldable display screens. [0003] Current flexible display modules are mainly stacked with bendable plastic films or ultra-thin glass covers (UTG, ultrathin glass). The entire display module has the disadvantage of being easily scratched while being bendable. In order to solve the above problems, the current mainstream method is to attach a rela...
