Claim 11:
12. A vehicle-mounted liquid crystal display device, comprising:
a liquid crystal display panel comprising a display area and a functional area configured to transmit infrared light, wherein the liquid crystal display panel comprises an array substrate and a color filter substrate, the array substrate comprises a plurality of insulating layers, the color filter substrate is arranged opposite to the array substrate and comprises a plurality of insulating layers, wherein in the array substrate and/or the color filter substrate, a number of reflective interfaces formed by adjacent insulating layers of different refractive indices located in the functional area is greater than a number of adjacent reflective interfaces with different refractive indices located in the display area, and an absolute value of a difference in refractive indices of adjacent insulating layers on both sides of the reflective interface is greater than or equal to a first preset threshold;
an infrared camera arranged on a side of the array substrate away from the color filter substrate, and the infrared camera arranged on the functional area.
