Abstract

The present invention relates to an optical film, which allows a user to enjoy a stereoscopic image at various positions and angles by improving the viewing angle of stereoscopic glasses that is used to watch a stereoscopic image, a method of producing the optical film, and stereoscopic glasses and a stereoscopic display including the optical film. The optical film includes: a first base; a polarizing film stacked on the first base; a second base stacked on the polarizing film; and a hybrid liquid crystal layer formed on the second base; in which the hybrid liquid crystal layer includes: an alignment layer formed on the second base at an angle of 45° or -45° from a stretching direction of the polarizing film and rubbed in parallel with the surface of the second base; and horizontally-aligned liquid crystals and vertically-aligned liquid crystals that are aligned in parallel with and perpendicular to the rubbing direction on the alignment layer.
