Dual-view display panel and display device

A method for providing a dual-view display panel, the method comprising:

• providing a backlight source configured to provide a collimated light;
• providing a liquid crystal grating in a light-exiting direction of the backlight source;
• providing a color film layer on a side of the liquid crystal grating away from the backlight source, wherein the color film layer comprises a plurality of first pixel areas and a plurality of second pixel areas;
• and
• providing a light-shielding area between the first pixel area and the second pixel area which are adjacent to the light-shielding area;
• wherein the liquid crystal grating is configured to diffract the collimated light emitted by the backlight source to the first pixel area or the second pixel area.
