A retardation compensatorfor compensating for residual retardation of a liquid crystal panelincludes a retardation compensating platehaving birefringence. An in-plane retardation Rof the retardation compensating plateand an in-plane retardation Rof the liquid crystal panelsatisfy a relationship of 1&#x3c;R/R&#x2266;10, thereby allowing changes in the amount of compensated retardation among rotation angles occurring when the retardation compensating plateis set with respect to the liquid crystal panelto be confined within narrow limits. Therefore, the contrast can be adjusted readily, and variations in residual retardation among the individual liquid crystal panelscan be accommodated flexibly.

Retardation compensating plate to compensate residual retardation of a liquid crystal panel, a compensator, a liquid crystal display device, and a projection image display apparatus having the same

An optical packaged body capable of preventing generation of a wrinkle, deflection, and warpage, and capable of being thinned is provided. The optical packaged body includes a support medium and a packaging film that covers the support medium in a state of being applied with shrinkage force. The packaging film has an optical function section that acts on light from a light source in at least one of a first region into which the light from the light source enters and a second region from which the light from the light source is emitted after passing through the optical packaged body when the light source is arranged on one face side of the optical packaged body.
