Patent number: 8018557Abstract: A retardation compensator 40 for compensating for residual retardation of a liquid crystal panel 11 includes a retardation compensating plate 50 having birefringence. An in-plane retardation R0c of the retardation compensating plate 50 and an in-plane retardation R0p of the liquid crystal panel 11 satisfy a relationship of 1<R0c/R0p?10, thereby allowing changes in the amount of compensated retardation among rotation angles occurring when the retardation compensating plate 50 is set with respect to the liquid crystal panel 11 to be confined within narrow limits. Therefore, the contrast can be adjusted readily, and variations in residual retardation among the individual liquid crystal panels 11 can be accommodated flexibly.Type: GrantFiled: March 15, 2006Date of Patent: September 13, 2011Assignee: Sony CorporationInventors: Yutaka Muramoto, Satoshi Sekino, Hideki Terashima, Tatsuya Harima, Sachie Shoji, Noriaki Doi, Tokuhiro Morioka
