Abstract

Official abstract text for this publication.

There is provided an electrically controllable birefringence liquid crystal display (ECB-LCD) device, including: a liquid crystal panel including a first substrate, a second substrate, and a liquid crystal cell interposed between the first substrate and the second substrate and including a liquid crystal having positive dielectric anisotropy, the liquid crystal cell having a cell gap of 1 to 5 μm and operating in an ECB mode; a first polarizer disposed on an upper portion of the first substrate and having a first absorption axis; a second polarizer disposed on a lower portion of the second substrate and having a second absorption axis; a first liquid crystal film interposed between the first substrate and the first polarizer; and a second liquid crystal film interposed between the second substrate and the second polarizer; wherein the first liquid crystal film includes a first base substrate; and a first liquid crystal layer formed on a surface of the first base substrate and including a nematic liquid crystal splay-aligned such that a maximum tilt angle is 20° to 90° from an in-plane direction to a thickness direction; and wherein the second liquid crystal film includes a second base substrate; and a second liquid crystal layer formed on a surface of the second base substrate and including a horizontally aligned nematic liquid crystal.
