The present application relates to an optical film and a use thereof. In the present application, through control of an alignment state of a liquid crystal compound in a liquid crystal layer, the liquid crystal layer may exhibit so-called reverse-wavelength dispersion while forming a single thin layer. An optical film including the liquid crystal layer may show optical modulation in a display device such as a liquid crystal display (LCD), organic light emitting device (OLED), or the like, or may be used in various applications, for example, as an optical element capable of improving light utilization efficiency, an element for implementation of a stereoscopic image and quality improvement thereof, and so forth. |
