Abstract: An optical film includes a rough surface having multiple measuring points constituting multiple virtual measuring planes in a given unit measuring area. A normal to each virtual measuring plane has an angle with a normal to a reference plane. On the reference plane, the projection area of the virtual measuring planes having the angle larger than 20 degrees ranges from 31% to 60% of the projection area of the given unit measuring area. The projection area of the virtual measuring planes having the angle larger than 50 degrees is less than 7% of the projection area of the given unit measuring area. 25% of the measuring points has the height larger than a first height. 75% of the measuring points has the height larger than a second height. The first height and the second height have a difference not less than 0.6 ?m and not larger than 2.5 ?m.

Abstract: An anti-glare substrate, an anti-reflection film, and a display device are disclosed. The anti-glare substrate includes a first surface and a second surface disposed on opposite sides. The first surface includes a plurality of protrusion structures. Each protrusion structure includes a plurality of inclined planes. There is an angle ? between the normal direction of each inclined plane and the normal direction of the second surface. The sum of the vertical projection area of the inclined planes with ? less than 2.5° on the second surface is A<2.5, wherein the vertical projection area of the inclined planes is AT, wherein A < 2.5 A T ? 100 ? % ? 3.58 % . The anti-reflection film is for use with an anti-glare substrate. For a first assembly formed by disposing the anti-reflection film on the anti-glare substrate, the reflectances to blue ray, to green ray, and to red ray are close. The display device includes the anti-glare substrate and a display panel.
