Abstract: A display apparatus includes a display panel having a first display region, a second display region and an opening region. When the display apparatus is in a black state, the first display region has a first luminance value I1, the second display region and the opening region have a first luminance difference value DI1, the first display region and the second display region have a second luminance difference value DI2, and each of a ratio of DI1 to I1 and a ratio of DI2 to I1 ranges from 0.001 to 0.1.

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.
