Abstract
A liquid crystal display including an upper panel having an upper alignment layer, a lower panel having a lower alignment layer, and a liquid crystal layer including liquid crystal molecules interposed between the upper panel and the lower panel. Each of the liquid crystal molecules has different refractive indexes and different permittivities with respect to each axis direction. The upper alignment layer and the lower alignment layer are vertical alignment layers and have a rubbing direction, respectively. Before the application of an electric field, a first axis of each liquid crystal molecule is aligned in a vertical direction by the vertical alignment layer, and a second axis of each liquid crystal molecule is aligned in a direction parallel to the rubbing direction, and, after the application of the electric field, one having the largest permittivity of the axis directions of the liquid crystal molecule is aligned in parallel to the applied electric field.
