Abstract

A display panel is provided. In the display panel, a width-to-length ratio of a sub-channel of a compensation transistor adjacent to a drive transistor is less than a width-to-length ratio of a channel of a first initialization transistor, so that an effect of an increase in an electrical potential of a gate of the drive transistor affected by an electrical leakage of the compensation transistor is canceled by an effect of a decrease in the electrical potential of the gate of the drive transistor affected by an electrical leakage of the first initialization transistor, so as to prevent an electrical leakage of each transistor from causing changes in the electrical potential of the gate of the drive transistor, thereby reducing a problem of the flickering display.
