Optical compensating sheet, polarizing plate, and liquid-crystal display

摘要: An optical compensatory sheet comprises a cellulose acetate film. The film contains 100 weight parts of having an acetic acid content 59.0 to 61.5% and 0.01 20 aromatic compound at least two rings. has Re retardation value measured 550 nm (Re550) in the range 0 200 Rth (Rth550) 70 400 nm. further thickness 10 μm. is used liquid crystal display.
