摘要： An illuminating light incidence mirror for introducing an illuminating light to reflection-type liquid crystal panels is provided in one of two pupil division regions constituting a pupil region of a projection lens, and reflected lights directly reflected by the reflection-type liquid crystal panels are transmitted through the other pupil division region of the projection lens and projected. In dark display, the reflected lights from the reflection-type liquid crystal panels and surface-reflected lights reflected by surfaces of the reflection-type liquid crystal panels are blocked by polarizing plates. Further, since &lgr;/4 plates and the polarizing plates are provided at inclinations with respect to the reflection-type liquid crystal panels, respectively, projection of surface-reflected lights from the &lgr;/4 plates and the polarizing plates onto a screen can be avoided.

摘要： A direct-view display apparatus provides improved image quality by preventing the formation of a stripe pattern caused by parallax effects. A liquid-crystal panel for active matrix driving is disposed. A microlens array consisting of a plurality of microlenses formed in corresponding relationship to each pixel in the liquid-crystal panel is placed on a surface of a substrate of the liquid-crystal panel. A field lens and an eyepiece are disposed in this order between the microlens array and an observer. The field lens serves to converge the principal rays emerging from the microlens array in parallel with an optical axis onto the eyepiece, so that a moire pattern caused by parallax effects can be prevented from being formed and the image quality can thus be improved. Light from backlights are passed through display panels, respectively consisting of liquid-crystal cells, microlens arrays, and field lenses, and are superimposed by a crossed dichroic prism. The observer views the light superimposed by the crossed dichroic prism, i.e. a color image, through an eyepiece.
