Abstract:
1. A method of fabricating a compensation film, comprising: printing an alignment film on a substrate; evaporating a solvent of the alignment film at the temperature range of 60-80° C. and aligning a LC molecule of the alignment film; hardening the alignment film at the temperature range of 80-200° C.; applying a first alignment process including a rubbing process to the alignment film; applying a second alignment process including a first irradiation process using a beam without any mask to an entire surface of the alignment film applied with the first alignment process to secure an alignment uniformity of a coatable retarder liquid crystal (“LC”) material; coating a the coatable retarder liquid crystal (“LC”) material on the alignment film applied with the second alignment process; and hardening the retarder LC material by performing a second irradiation process using non-polarized ultraviolet light, wherein the beam is directly applied to the alignment film to align the alignment film, wherein the first irradiation process shortly after the rubbing process is performed, and wherein the beam is irradiated in the same direction as a rubbing direction of the rubbing process, wherein the rubbing process is performed by rubbing the alignment film with a rubbing cloth, wherein the rubbing cloth is one of velvet, rayon, nylon, wherein the beam is one of ion beam, plasma-beam, and electron-beam irradiated on an entire surface of the rubbed alignment film.
