Abstract
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.
