Abstract
A multilayer optical film includes a plurality of polymeric layers arranged sequentially adjacent to each other. A difference in thickness between spaced apart first and second polymeric layers in the plurality of polymeric layers is less than about 10%. Each polymeric layer that is disposed between the first and second polymeric layers has a thickness less than about 400 nm. Each layer in a group of at least three polymeric layers in the plurality of polymeric layers that are disposed between the first and second polymeric layers has a thickness greater than an average thickness of the first and second polymeric layers by about 20% to about 500%. The group of at least three polymeric layers includes at least one pair of immediately adjacent polymeric layers.
