Claim 12:
13. A display panel, comprising:
a first base substrate;
a second base substrate, arranged opposite to the first base substrate;
a liquid crystal layer, located between the first base substrate and the second base substrate;
a first alignment film, located at a side of the first base substrate facing the liquid crystal layer;
a second alignment film, located at a side of the second base substrate facing the liquid crystal layer;
a polarizer, located at a side of the first base substrate away from the liquid crystal layer; and
a quarter-wave plate, located between the polarizer and the first base substrate,
wherein the first alignment film has a first alignment direction, and the second alignment film has a second alignment direction,
an angle between a center line of an included angle between the first alignment direction and the second alignment direction and a slow axis of the quarter-wave plate is in a range from 75 to 105 degrees,
the display panel further comprises: a scattering film, wherein the scattering film is configured to scatter light incident thereon,
wherein the scattering film comprises a scattering structure and a reflective element, the scattering structure and the reflective element are located on the second base substrate, the scattering structure comprises a plurality of protrusions and recessed portions located between adjacent ones of the plurality of protrusions, the scattering structure is located at a side of the second base substrate facing the first base substrate, and the reflective element is located at a side of the scattering structure away from the second base substrate, and is conformally formed on a surface of the scattering structure away from the second base substrate.
