Abstract

This article describes the wide viewing angle liquid crystal display (LCD) which has a bend-alignment, or twisted nematic (TN) liquid crystal cell to use the optically compensated film. The optically compensated film is composed by negative monoaxial film (just like discotic film, which made from discotic liquid crystal), and biaxial film.

Liquid Crystal Display

        This article describes the wide viewing angle liquid
crystal display (LCD) which has a bend-alignment, or twisted nematic
(TN) liquid crystal cell to use the optically compensated film.  The
optically compensated film is composed by negative monoaxial film
(just like discotic film, which made from discotic liquid crystal),
and biaxial film.

  Figure.1-A and 1-B show the components of these LCD device.  In
these figure, bend-alignment liquid crystal layer (a) and TN liquid
crystal layer (e) are aligned along the direction of the arrow.  The
negative monoaxial film layers (b) are also alignment along the
direction of the arrow.  Biaxial film layers (c)'s slow axis is
parallel or perpendicular to the transmittance axis of the polarizer
(d).
