Display panel and display device

The display panel and the display device comprise an array substrate and an opposite substrate which are oppositely arranged, the opposite substrate comprises a first substrate body, and a black matrix with a plurality of sub-pixel openings is arranged on the side, facing the array substrate, of the first substrate body; the array substrate comprises a plurality of pixel electrodes arranged in an array and a plurality of data lines arranged at intervals in the first direction. Each data line comprises a first straightening part extending in the second direction, the orthographic projection of the first straightening part on the first substrate and the orthographic projection of the sub-pixel opening close to the boundary of one side of the first straightening part are arranged side by side, and the second direction is perpendicular to the first direction; the pixel electrode comprises a plurality of strip-shaped electrodes arranged in the first direction, each strip-shaped electrode comprises a sharp corner part, the strip-shaped electrode closest to a data line electrically connected with the pixel electrode is a first strip-shaped electrode, and the orthographic projection of the sharp corner part of the first strip-shaped electrode on the first substrate body is overlapped with the orthographic projection of the black matrix.
