MULTILAYERED OPTICAL FILM AND DISPLAY DEVICE

摘要

Disclosed is an optical film. The optical film includes a first optical phase delay layer having the relationship nx1>=ny1>=nz; a second optical phase delay layer disposed at the lower part of the first optical phase delay layer and satisfying the relationship nx2≒ny2< nz2; and a third optical phase delay layer disposed at the upper part of the first optical phase delay layer and satisfying the relationship nx3≒ny3< nz3.
