Abstract: A display panel includes data lines and scanning lines in a display region, and a demultiplexer in a non-display region. The demultiplexer includes m branches. m is an integer. m≥2. Each branch includes a switching transistor which includes a first electrode coupled with an input terminal of the demultiplexer, a second electrode coupled with one of the data lines, and a control electrode for receiving a switching control signal. The demultiplexer includes a first demultiplexer including a compensation transistor, of which first and second electrodes are short-circuited. The compensation transistor is coupled with the data line and has a control electrode for receiving a compensation control signal. The compensation control signal received by the compensation transistor in the branch has one functional rising edge in a period during which the scanning line provides an effective level signal once.

The first substrate includes a base substrate, first fanout wires and a planarization layer that are arranged at a side of the base substrate proximate to the second substrate. The first fanout wires are arranged in the non-display area and at a side of the planarization layer facing away from the base substrate. Each first fanout wire includes first to third wires that are connected in sequence. A distance between adjacent second wires is greater than a distance between adjacent first wires, and is greater than a distance between adjacent third wires. The planarization layer is provided with a first opening, and the first opening overlaps with the sealant and a second wire area formed by second wires.
