Abstract: A liquid crystal display panel and a vehicle-mounted liquid crystal display device are provided. In the liquid crystal display panel, in an array substrate and/or a color filter substrate, a number of reflective interfaces in a functional area is greater than a number of reflective interfaces in a display area. Under the condition that an infrared optical transmittance is not affected, a reflectivity of light in the functional area is improved compared to the display area. This reduces or even eliminates a brightness difference between the functional area and the display area when a display is completely black.

Abstract: An electrostatic discharge protection wiring is provided, and the electrostatic discharge protection wiring includes a gate signal line, a driving circuit, a gate connection line, and a source/drain. By disposing the bent gate connection line at an end of the gate signal line, the electrostatic discharge passes through the bent gate connection line to lose a part of current, thus reducing an effect of the electrostatic discharge to prevent bright spots at edges of panels caused by the weak electrostatic discharge.
