Display panel and display device

The invention provides a display panel and a display device. The display panel comprises a first substrate, a second substrate opposite the first substrate and a pixel array. The pixel array is arranged between the first substrate and the second substrate and comprises at least one pixel; the pixel has an electrode layer and a data line arranged on the side, facing the second substrate, of the first substrate; the substrate layer comprises a first main electrode and a plurality of branch electrodes; the first main electrode extends in the first direction and intersects the data line, and is connected with the branch electrodes; the branch electrodes extend in the second direction; at least an angle of y is formed between the second direction and the first direction; y is greater than B1 and less than A1. The equation of A1 is A1=-1.28*10 (x) +0.0047722(x) -0.383068 (x)+59.494865, and the equation of B1 is B1=-2.38*10 (x) +0.0093751(x) -1.098394(x)+81.919357; y is greater than 45 degrees and is not greater than 70 degrees, and x represents the number of pixels per inch of the display panel.
