Abstract
The present invention relates to a window and light guiding film therein. The light guiding film includes 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. The refraction index of the microstructure is 1.9 to 2.6. A first inclination angle is between the first surface and a reference plane, the reference plane is perpendicular to the film base, and a second inclination angle is between the second surface and the reference plane, wherein the first inclination angle is less than or equal to the second inclination angle.
