Abstract
A display panel comprises a display substrate, a phase difference layer and a polarizer. The phase difference layer is disposed on a display side of the display substrate. The polarizer is disposed on one side of the phase difference layer which is away from the display substrate. The direction of the absorption axis of the polarizer is parallel to or perpendicular to the stretching direction of the polarizer, and the included angle between the absorption axis of the polarizer and the optical axis of the phase difference layer is not equal to 0° or 90°.
