    Abstract: A liquid crystal display includes a substrate, a plurality of signal lines, a gate driver, and a sealant. The substrate includes a display area and a peripheral area outside the display area. The signal lines are integrated with the substrate and include a clock signal line. The gate driver includes a stage located between the clock signal line and the display area. The stage is integrated with the substrate and is configured to apply a gate voltage to the display area. The sealant is distributed over part of the peripheral area. A seal region where the sealant is distributed includes a seal line, and the clock signal line is located within the seal line. The clock signal line is located further away from the stage than the other signal lines.
