A liquid crystal display device includes a backlight assembly, a liquid crystal display panel, a capacitive type touch function key, a cover film and a receiving container. The backlight assembly is configured to generate light. The liquid crystal display panel is disposed on the backlight assembly. The liquid crystal display panel includes an array substrate and an opposing substrate facing the array substrate. The capacitive type touch function key is disposed adjacent to a side surface of one of the array substrate and the opposing substrate. The cover film overlaps the liquid crystal display panel and the capacitive type touch function key. The receiving container receives the backlight assembly, the liquid crystal display panel and the capacitive type touch function key.
