Abstract
The present invention relates to a light guiding film including a film base and at least one microstructure. The microstructure is disposed on a side of the film base, and comprises a first surface and a second surface. A first inclination angle is between the first surface and a reference plane, the reference plane is perpendicular with the film base, and a second inclination angle is between the second surface and the reference plane. The total energy of the output light beams with the output angles from 85 to 120 degrees is more than 40% of the total energy of the output light beams with the output angles from 0 to 180 degrees. Therefore, the light guiding film can guide the incident light beams into a room near horizontally and avoid glare.
