Disclosed is a homeotropic alignment liquid crystal film without an alignment layer and a method for preparing the same. More specifically, the present invention relates to a homeotropic alignment liquid crystal film without using a separate alignment layer to induce a homeotropic alignment of the liquid crystal in which a liquid crystal layer has a homeotropic alignment property by coating a polymerizable and reactive liquid crystalline mixture solution including a predetermined surfactant on a plastic substrate whose surface are hydrophilic-treated, and drying and UV irradiating the mixture solution; a method for preparing the same. The homeotropic alignment liquid crystal film prepared according to the present invention may be very useful as a major component of a viewing-angle compensation film and a retardation film, etc. in LCD, and has advantages of simplicity of the manufacturing process, its shortened manufacturing time, its mass production, etc. |
