发明名称 ELLIPTIC POLARIZING PLATE
摘要 PROBLEM TO BE SOLVED: To prevent the occurrence of foaming and peeling in high-temperature, high-humidity environment and to prevent optical performance from deteriorating by providing sides which shift within a specific range in parallel to respective main surfaces between a polarizing plate end side and a phase difference plate end side after a durability test under specific conditions. SOLUTION: The polarizing plate 1 and phase difference plate 3 are stuck together across an adhesive layer 2 formed of an acryl-based adhesive, and the other surface of the phase difference plate 3 is stuck on a glass plate 5 for a liquid crystal cell across an adhesive layer 4. This laminate is thermally processed to cause the polarizing plate 1 and phase difference plate 3 deform owing to heat and the shrinkage of the polarizing plate 1 is large, so the adhesive layer 2 also deforms. The polarizing plate 1 is different in shrinkage behavior between an absorption axis direction and its orthogonal direction. For example, when the laminate is exposed at 90 deg.C for 24 hours, a polarizing plate end side 1a and a phase plate end side 3a constituting the same end side of the elliptic polarizing plate 6 shift in parallel to the respective main surfaces. At least one side having a shift (x) of 100 to 450μm is provided.
