The disclosure provides a liquid crystal display (LCD) panel, a manufacturing method thereof, and an LCD device. The LCD panel adopts a structure with multiple electrodes and dual-frequency liquid crystals. When a temperature of the LCD panel is low (below 0° C.), the LCD panel is driven at high frequency, so that it emits more heat. Therefore, a working temperature of the LCD panel is increased without adding a heating element. LCD devices using such LCD panels have wide working temperature ranges, and are well suited to be used outdoors.

A rear-view mirror includes a body, wherein the body includes a first polarizer, a dimming layer, a transflective polarizer, and a display component which are sequentially laminated. The dimming layer is configured to adjust a polarization direction of light passing through the dimming layer. By adjusting the polarization direction of the light passing through the dimming layer via the dimming layer, the reflectivity and transmittance of the transflective polarizer to the light can be changed, such that both an anti-glare function and a display function of the rear-view mirror can be achieved.
