Abstract

The invention discloses a flexible display device and a preparation method thereof. The flexible display device comprises a bending area and a non-bending area. The flexible display device further comprises at least two functional layers, and at least one bonding layer located between the at least two functional layers, wherein each bonding layer comprises a first bonding unit and a second bondingunit, and the first bonding unit and the second bonding unit are arranged adjacently; the crosslinking density of the first bonding unit is greater than that of the second bonding unit, and the areaof the vertical projection of the first bonding unit in the bending area on the plane where one of the at least two functional layers is located is larger than the area of the vertical projection of the first bonding unit in the non-bending area on the plane where one of the at least two functional layers is located. According to the flexible display device provided by the embodiment of the invention, the problem of stress concentration during bending or curling of the flexible display device can be reduced.

Description

technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular to a flexible display device and a manufacturing method thereof. Background technique [0002] With the development of display technology, users not only have higher and higher requirements on the types and performances of the display device, but also have higher and higher requirements on the appearance of the display device. [0003] Currently, flexible display devices with a bending or rolling function are attracting more and more attention from users. [0004] However, when the flexible display device is bent or curled, the bending area or curling area bears too much stress, and the stress cannot be released, which leads to delamination between film layers and affects the appearance of the flexible display device. Contents of the invention [0005] The invention provides a flexible display device and a preparation method thereof, which can reduc...
