发明名称 OPTICALLY COMPENSATED POLARIZING PLATE AND LIQUID CRYSTAL DISPLAY DEVICE
摘要 PROBLEM TO BE SOLVED: To develop an optically compensated polarizing plate which is thin and excellent in the production efficiency and with which a liquid crystal display device having excellent display quality can be formed. SOLUTION: The optically compensated polarizing plate consists of a laminated body 1 of a phase difference plate 12 or 13 and a polarizing plate 11 or 14. When these two standard laminated bodies having the same structure are disposed with the phase difference plates are placed on the inside, and the polarizing plates are arranged in the cross-Nicol position, the leakage rate of light in the normal direction is <=0.2% on the entire surface. The liquid crystal display device has this optically compensated polarizing plate on at least one side of a liquid crystal cell 3. Thus, the extremely thin optically compensated polarizing plate is obtained by using one phase difference plate, and the thin liquid crystal display device which is excellent in display quality such as contrast and homogeneity while compensating the phase difference of a TFT liquid crystal cell, is formed.
