Abstract:
A double super twisted nematic (DSTN) liquid crystal display (LCD) comprising:a liquid crystal display cell having first and second transparent substrates arranged parallel to each other, first and second orientation layers formed on opposing surfaces of the first and second transparent substrates, respectively, a first liquid crystal sealed between the first and second orientation layers, and indium tin oxide (ITO) electrodes formed on the opposing surfaces of the first and second transparent substrates while crossing each other; anda liquid crystal compensation cell having a third transparent substrate attached to the second transparent substrate, a fourth transparent substrate arranged in parallel to the third transparent substrate, third and fourth orientation layers formed on each opposing surface of the third and fourth transparent substrates, and a second liquid crystal sealed between the third and fourth orientation layers,wherein a pre-tilt angle of the first liquid crystal sealed between the first and second orientation layers is greater than a pre-tilt angle of the second liquid crystal sealed between the third and fourth orientation layers such that the difference between changes in the refractive index anisotropies of the first and second liquid crystals is compensated for.
