摘要： Provided is a display panel. The display panel includes: a substrate, at least one row of light-emitting elements disposed on the substrate, a plurality of pixel drive circuits, a plurality of connection lines, and a plurality of compensation portions. A length of a first connection line electrically connected to a first pixel drive circuit is less than a length of a second connection line electrically connected to a second pixel drive circuit. A capacitance of the first connection line is compensated by electrically connecting the compensation portion to the first connection line, and thus a difference between the capacitance of the first connection line and a capacitance of the second connection line is reduced.
