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.

Optical film including microstructure layer and display device including the same

An optical film includes a grid layer having a first surface, a second surface, light-shading portions, and light-transmitting portions. The light-shading portions and the light-transmitting portions are located between the first surface and the second surface, and the light-shading portions and the light-transmitting portions are alternately arranged along the first surface. Each light-shading portion has a third surface, a fourth surface, a fifth surface, a sixth surface, and a seventh surface. An angle between the fourth and third surfaces is A1, an angle between the fifth and third surfaces is A2, an angle between the sixth and second surfaces is A3, and an angle between the seventh and second surfaces is A4. Wherein 85°<A1≤90°, 85°<A2≤90°, 0°<A3<85°, 0°<A4<85°, A2≠A4, and A1≠A3. A display device is also provided.
