Abstract
A liquid crystal display comprises: first and second panels facing each other; a compensation film and a first polarizer disposed on the first panel, the compensation film having phase retardation characteristics; and a second polarizer having a supporting film disposed on the second panel, the supporting film having phase retardation characteristics. In alternative embodiments, a supporting film is used in place of the compensation film. The supporting film has retardation characteristics.
