DISTRIBUTIVE COMPENSATOR AND PROJECTING LIQUID-CRYSTAL DISPLAY DEVICE |
摘要 |
<p>[Problem] There is provided a distribution-type compensator which can optimize contrast in the whole screen region using an optical system in which a field lens is disposed between a reflection-type liquid crystal element and a WG-PBS and a projection-type display apparatus mounting the same. [Solution] A distribution-type compensator 11 has an in-plane retardation of 18 nm ± 5 nm in a rectangular effective region with a long side and a short side. The slow axis direction of the distribution-type compensator 11 changes continuously in a plane of the effective region and an angle difference between slow axis directions at any two positions in the effective region has a maximum value in a range of 10 degrees to 30 degrees. The distribution-type compensator 11 is mounted to a projection-type display apparatus.</p> |
