Abstract
The present invention provides a 3D display panel and a 3D display system. The system comprises the 3D display panel and polarizer glasses. A first optical retardation value of a quarter wave (λ/4) retarder film of the 3D display panel can be designed according to a second optical retardation value of the polarizer glasses. The present invention can improve a narrow viewing angle problem existing in the conventional 3D display.
