Abstract

The invention provides a flexible display device which comprises a bendable display panel and at least one polarizer. The polarizers comprise polarizing films, absorption axes parallel to stretching directions corresponding to stretching operations are formed after the action of the stretching operations in the preparation process of the polarizing films, the stretching directions corresponding to stretching operations of the polarizing films are consistent with bent directions of the bent display panel, the bending-resistant degree of the polarizing films is enhanced, and performances of the flexible display device are enhanced.

Description

technical field [0001] The present invention relates to the technical field of flexible display, in particular to a flexible display device. Background technique [0002] In recent years, the advantages of flexible display devices such as thinness, portability, and bendability have become increasingly prominent, and are more and more favored by people. In order to reduce the reflectivity and light transmission performance of the display, polarizers are widely used in OLED (Organic Light Emitting Diode Display) and LCD (Liquid Crystal Display) display devices. In flexible display devices, in addition to meeting certain optical requirements, polarizers also need to be thinner and more resistant to bending. However, the existing polarizer has a thickness of less than 50um, and cracks are still prone to occur during the bending process of module stacking, which affects the performance of the flexible display device. [0003] To sum up, in the flexible display device of the pri...
