Abstract:
A liquid crystal display device and a viewing angle switching method are provided. The liquid crystal display device includes a display panel, a backlight source, and a light adjustment liquid crystal film disposed between the display panel and the backlight source. The light adjustment liquid crystal film includes an upper substrate, a lower substrate disposed opposite to the upper substrate, and a liquid crystal layer located between the upper substrate and the lower substrate. The upper substrate is provided with an upper electrode on a side thereof facing the lower substrate. The lower substrate is provided with a lower electrode on a side thereof facing the upper substrate. The light adjustment liquid crystal film is configured to change a backlight exit angle of the light emitted by the backlight after passing through the display panel by applying a voltage between the upper electrode and the lower electrode.

Claim (Index 5):
The viewing angle switchable liquid crystal display device according to  claim 4 , wherein one of the two light adjustment liquid crystal films is disposed between the display panel and the backlight source, and the other light adjustment liquid crystal film is disposed above the display panel.
