Claim 8:
9. 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 plurality of scattering units, each of the plurality of scattering units comprises a rod-like shape, and each of the plurality of scattering units comprises a first portion; an included angle between the first portion and the first base substrate is an acute angle, and an extending direction of the first portion is the same as a direction in which a reflectivity of the display panel is maximum without the scattering film,
wherein each of the plurality of scattering units further comprises a second portion, an included angle between the first portion and the second portion is greater than 90 degrees and less than 180 degrees, the first portion has a first section in a direction perpendicular to the first base substrate, the second portion has a second section in the direction perpendicular to the first base substrate, the first section is connected with the second section, an included angle between the first section and the direction perpendicular to the first base substrate is different from an included angle between the second section and direction perpendicular to the first base substrate, and the second section is provided on a side of the first section away from the first base substrate.
