The in-plane switching mode liquid crystal panel comprises a liquid crystal layer having a Rin (550) value in a range of 310 nm to 350 nm. An absorption axis of the upper polarizer and an absorption axis of the lower polarizer are orthogonal. The lower polarizer is adjacent to a light source as compared to the upper polarizer. The liquid crystal display further comprises, as retardation films, a positive biaxial retardation film having a Rin (450)/Rin (550) value in a range of 0.99 to 1.01, and a negative C plate between the upper polarizer and the in-plane switching mode liquid crystal panel."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Liquid crystal display device","description":"Provided is a liquid crystal display device, comprising an upper polarizer, an in-plane switching mode liquid crystal panel, and a lower polarizer.
