Inspection method and control of phase difference of optical compensation sheet |
| abstract |
The present invention relates to a saponification method of an optical compensation sheet, and more particularly, to an optical compensation sheet having a polyvinyl alcohol-based alignment layer formed on a transparent substrate film and an optically anisotropic layer having a liquid crystal polymer fixed thereon. TN mode liquid crystal display with optical compensatory sheet minimizes damage or peeling of optically anisotropic layer by immersing in 50-60 ° C saponification solution containing 3-6N alkali agent for 10-50 seconds, so that wide viewing angle and high front It relates to an inspection method of an optical compensating sheet capable of exhibiting a contrast ratio. |
