    Abstract: A display panel includes a substrate, sub-pixels, data lines and a pixel defining layer. The data lines are divided into data line groups. Each data line group includes a first data line, a second data line and a third data line sequentially arranged in a first direction. Adjacent second and third data lines are substantially symmetrical about an axis. The second data line and the third data line each include first straight segments and first bending segments alternately connected. For first bending segments of the adjacent second and third data lines, each is bent in a direction away from another. The pixel defining layer is provided therein with photosensitive openings. An orthogonal projection, on the substrate, of a photosensitive opening is located between orthogonal projections, on the substrate, of adjacent first bending segments of a second data line and a third data line.
