Abstract
A visual angle regulator of a Liquid Crystal Display (LCD) is arranged between an LCD panel and a backlight. When the visual angle regulator is applied with a voltage, the LCD is in a narrow visual angle mode. When the visual angle regulator is not applied with a voltage, the LCD is in a wide visual angle mode, which allows the LCD to have the wide visual angle mode and the narrow visual angle mode.
