Abstract
The present disclosure provides an anti-reflection film and a flexible display device. The anti-reflection film includes: a linear polarization film stretched in a first stretching direction; and a phase delay film stretched in a second stretching direction. When a light beam passes through the linear polarization film, the light beam is converted into a linear polarized light, and when the light beam passes through the phase delay film, the phase delay film changes a phase of the light beam. A first acute angle α is formed between the first stretching direction and the second stretching direction. The anti-reflection film has a folding axis, and a vertical line of the folding axis is located within the first acute angle α.
