  • Patent number: 9891360
    Abstract: Provided are an optical film and a display device including the same. The optical film may be disposed at the outermost side of a display device, such as a liquid crystal display or an organic light emitting display, or at an outside of a polarizing layer of the display in which the polarizing layer is disposed at a visible side. The film disposed as described above may overcome degradation of brightness that may occur when an observer watches an image with polarizing sunglasses. The optical film may also have hardness suitable for its use.
