The present invention relates to a display panel including a display area. The display area includes pixel units arranged in an array and signal lines connecting the pixel units; the display area includes a first display area and a second display area, and the number of the pixel units in each row in the first display area is less than the number of the pixel units in each row in the second display area; the signal lines include first signal lines and second signal lines, the first signal lines are located in the first display area and connected to the pixel units of each row in the first display area, the second signal lines are located in the second display area and connected to the pixel units of each row in the second display area, and the width of the first signal line is smaller thanthe width of the second signal line. The display panel adopts two kinds of signal lines of different widths, so that the load amounts of the signal lines of the first display area and the second display area are the same, and the illuminating currents are the same, so that the illuminating brightness of the display panel is uniform in each area.
