Abstract
A polarizing-axis control plate includes first and second polarization areas and a polarizing-axis control plate area shading part arranged at a boundary between these polarization areas and arranged in a position corresponding to an image generating area shading part to shade all or part of right-eye and left-eye image lights. When these image lights enter the first and second polarization areas respectively, the polarizing-axis control plate emits these image lights in the form of linearly-polarized lights whose polarizing axes intersect with each other at right angles or circularly-polarized lights whose polarizing axes are rotated in opposite directions. The image generating area shading part is arranged at a boundary between first and second modulated-light generating areas to shade incident light. The polarizing-axis control plate area shading part is formed to contain a plurality of straight lines each having a width narrower than a linewidth of the image generating area shading part.
