Abstract
A display device provided includes a display panel, a first backlight module, a second backlight module, a light sensor, and a viewing angle adjusting component. The first backlight module includes an optical element, and the viewing angle adjusting component is disposed corresponding to a display sensing area. When the optical element is in a fog state, the viewing angle adjusting component reduces an exit angle of backlight. When the optical element is in a transparent state, external light enters the light sensor through the viewing angle adjusting component and the first backlight module, which improves uniformity of backlight viewing angle.
