Abstract
The present disclosure provides a dual-view display panel and a display device. The dual-view display panel includes a backlight source, a liquid crystal grating and a color film layer. The backlight source is configured to provide a collimated light. The liquid crystal grating is provided in a light-exiting direction of the backlight source. The color film layer is provided on a side of the liquid crystal grating away from the backlight source. The color film layer comprises a plurality of first pixel areas and a plurality of second pixel areas. A light-shielding area is provided between the first pixel area and the second pixel area which are adjacent to the light-shielding area. The liquid crystal grating is used to diffract the collimated light emitted by the backlight source to the first pixel area or the second pixel area.
