ABSTRACT:
A liquid crystal display in which a negatively birefringent layer is used as both an orientation film and as a retarder in the display. An improved method of making such a display is also disclosed. In preferred embodiments, each of the orientation layers has a retardation value of from about -80 to -200 nm.
