Abstract

The present application relates to an optical film, a polarizing plate and a display apparatus. An example optical film can exhibit a desired phase lag characteristic over a wide range of wavelengths, and does not leak light even when inclined at an angle. For example, the optical film can exhibit ¼ phase lag characteristic, and can be used in a reflective or semi-permeable liquid crystal display or an organic light-emitting display apparatus, or similar.
