Abstract: A display panel includes data lines and a first wiring layer in a display region, and a cover layer located at a side of the first wiring layer facing toward a light-exiting direction of the display panel. The first wiring layer includes data connection lines and wiring segments. The data connection line is connected to a data lines and transmits a data voltage provided in the pad region to the data line. One wiring segment is spaced apart from the data connection line by a first breaking. The cover layer includes first cover portions and second cover portions. Along a direction perpendicular to a plane of the display panel, the first cover portions overlap the first breakings, and the second cover portions overlap the data connection lines and the wiring segments.
