AI Technical Summary
Technical Problem
When the existing display devices are folded, they are prone to cracks in the optical film, affecting the display effect.
Method used
The side with a larger crack strain in the longitudinal and transverse directions is provided on the optical film of the display device to form an angle of 15° to 120° with the folding axis to reduce the overlap between the direction of the crack strain during folding and the direction with a larger crack strain, thereby suppressing the occurrence of cracks.
Benefits of technology
It effectively prevents cracks in the optical film when the display device is folded, and improves the reliability and service life of the display device.

Abstract
A display device is provided that is foldable about a folding axis. The display device includes a display panel, a cover window on the display panel, and an optical film on the cover window. The optical film has a longitudinal direction and a lateral direction, and one of the longitudinal direction and the lateral direction of the optical film having a larger crack strain forms an angle with the folding axis in a range of 15 DEG to 120 DEG.
