摘要：
PROBLEM TO BE SOLVED: To provide a polarizing plate with optical compensation layer which contributes to reduction of the thickness and weight and is excellent in heat resistance and moisture resistance. SOLUTION: The polarizing plate 10 with optical compensation layer is prepared by stacking a polarizer 11, a first optical compensation layer 12, a second optical compensation layer 13 and a third optical compensation layer 14 in this order. The first optical compensation layer 12 is formed of a liquid crystal compound, has a refractive index distribution of nx>ny=nz and the in-plane retardation Re 1 is 200 to 300 nm. The second optical compensation layer 13 has a refractive index distribution of nx>ny=nz and the in-plane retardation Re 2 is 80 to 170 nm. The third optical compensation layer 14 is formed of a material presenting optically negative uniaxiality and the material is obliquely aligned. Preferably, the second optical compensation layer 13 and the third optical compensation layer 14 are stuck to each other via only an adhesive layer. COPYRIGHT: (C)2008,JPO&INPIT
摘要（中）：
要解决的问题：提供一种具有光学补偿层的偏光板，其有助于减小厚度和重量，并且耐热性和耐湿性优异。 解决方案：具有光学补偿层的偏振板10依次层叠偏振片11，第一光学补偿层12，第二光学补偿层13和第三光学补偿层14来制备。 第一光学补偿层12由液晶化合物形成，折射率分布为nx> ny = nz，面内相位差Re 1 为200〜300nm。 第二光学补偿层13的折射率分布为nx> ny = nz，面内相位差Re 2 为80〜170nm。 第三光学补偿层14由具有光学负单轴性的材料形成，并且材料倾斜地对准。 优选地，第二光学补偿层13和第三光学补偿层14仅通过粘合剂层彼此粘合。 版权所有（C）2008，JPO＆INPIT
