发明名称 Double super twisted nematic liquid crystal display with improved pre-tilt angles
摘要 A double super twisted nematic (DSTN) liquid crystal display (LCD) is provided. The DSTN LCD includes: 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 liquid crystal sealed between the first and second transparent substrates, and indium tin oxide (ITO) electrodes formed on the opposing surfaces of the first and second transparent substrates while crossing each other; and a liquid crystal compensation cell having a third transparent substrate attached on 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 orientation layers, and a liquid crystal sealed between the third and fourth orientation layers, wherein the pre-tilted angle of the liquid crystal sealed between the first and second orientation layers differs from the pre-tilted angle of the liquid crystal sealed between the third and fourth orientation layers such that the difference between changes in the refractive index anisotropies of the liquid crystals is compensated for.
