Abstract:
A method of fabricating a liquid crystal cell, comprising:obtaining a first substrate with a first orientation film having a first rubbing direction; obtaining a second substrate with a second orientation film having a second rubbing direction; spacing the first substrate and the second substrate apart from each other by a gap â€œdâ€  such that the first orientation film and the second orientation film are opposed to each other and such that the first rubbing direction and the second rubbing direction form an angle Ã¸ that is less than 90Â°; locating a first polarizer having a first transmittance axis on the exterior of the first substrate such that the first transmittance axis and the first rubbing direction form an angle (90Â°âˆ’Ã¸)/2; locating a second polarizer having a second transmittance axis on the exterior of the second substrate, wherein the second transmittance axis is perpendicular to the first transmittance axis, and wherein the second transmittance axis and the second rubbing direction form an angle (90Â°âˆ’Ã¸)/2; placing a liquid crystal having a twisted angle of in the gap â€œdâ€ , the gap â€œdâ€  produces optimum transmittance of the liquid crystal cell; and placing a compensation film on the second substrate; wherein the compensation film has a phase difference of 10 to 60 nanometers.
