Abstract
An electronic device which has a narrow viewing angle state and a wide viewing angle state includes a diffuser layer, a panel and a light source. The panel is disposed on the diffuser layer. The light source provides a light passing through the panel. In the narrow viewing angle state, the light has a first relative light intensity and a second relative light intensity. The first relative light intensity is the strongest light intensity, and the second relative light intensity is 50% of the strongest light intensity. The first relative light intensity corresponds to an angle of 0°, the second relative light intensity corresponds to a half-value angle, and the half-value angle is between −15° and 15°.
