A liquid crystal display device includes a display panel, a printed circuit board assembly, a chip carrier film structure connected to the display panel and the printed circuit board assembly, a frame, and an electrostatic discharge structure. The electrostatic discharge structure includes a grounding structure disposed on the printed circuit board assembly. A grounding element is electrically connected to a side of the grounding structure of the printed circuit board assembly. A peripheral electrostatic discharge trace is disposed between the frame and the display panel and is connected to the grounding element, and includes a first guiding portion. A voltage regulating element is electrically connected between the grounding structure of the printed circuit board assembly and the first guiding portion of the peripheral electrostatic discharge trace.
