Abstract
A display panel and a display device are provided. The display panel includes a first base substrate; a second base substrate opposite to the first base substrate; a liquid crystal layer between the first and second base substrates; a first alignment film at a side of the first base substrate facing the liquid crystal layer; a second alignment film at a side of the second base substrate facing the liquid crystal layer; a polarizer at a side of the first base substrate away from the liquid crystal layer; and a quarter-wave plate between the polarizer and the first base substrate. An angle between a center line of an included angle between the first alignment direction of the first alignment film and the second alignment direction of the second alignment film and a slow axis of the quarter-wave plate is in a range from 75 to 105 degrees.
