Abstract
A cover film is applied to a flexible display device. The cover film includes a light incident surface and a light exit surface. A plurality of concaves are provided on the light incident surface. Each of the concaves includes a first portion, and the first portion is arch shaped. By providing the plurality of concaves with an arched structure on the cover film, the flexible display device changes a light path less during a bending process, and rainbow ripples or water ripples may be avoided, thereby improving user experience. In addition, since the plurality of concaves are the arched structures with a certain radian, the plurality of concaves have a certain concentrating effect, so that brightness of a visible region of the flexible display device can be enhanced.
