Abstract
A display device including a display module and an illuminating module is disclosed. The illuminating module is disposed on a display surface of the display module, and includes a light source, a light guide plate, and an optical film. The optical film is disposed between the display module and the light guide plate, and includes a basal layer and a microstructure layer. The microstructure layer is disposed between a surface of the basal layer and the light guide plate, and includes multiple microstructures. Each microstructure includes a first surface and a second surface. A first angle is between the first surface and a datum plane. A second angle is between the second surface and the datum plane. The first angle and the second angle are greater than or equal to 40 degrees and less than or equal to 90 degrees.
