摘要：
A polarizing plate used for manufacturing a liquid crystal display with suppressed irregularity in brightness, a method of manufacturing the same, and a liquid crystal display using the same, are provided. The polarizing plate is formed having a laminate of a polarizing film and a transparent protective layer provided on at least one surface of the polarizing film. By heat-treating and subsequently reheat-treating, the laminate has a shrinkage force of at most 8N/10 mm width when the laminate is further left at 60° C. for 1 hour, and furthermore, the laminate has a single hue value b of at most 4.6 NBS.
