The present application can provide a polarizing plate which does not cause cracks or the like while having a thin thickness, does not induce warping or twisting in itself and does not induce the above problems even when applied to a display device such as an LCD or OLED."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Polarizing plate having specified ratio of polarizing film shrinkage force to protective film shrinkage force","description":"The present application relates to a polarizing plate having a polarizing film in which a light absorption axis is formed in one in-plane direction; a protective film formed on one side of the polariz","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11487148","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
