摘要： A projection optical system (6) comprises a relay optical system (61), a PBS prism (71), and two projection lenses (81). The image light beam from a DMD (5) enters the PBS prism (71) via the relay optical system (61), is polarization-split there, and is directed to a screen by means of the two projection lenses (81). Displaying an image by means of the DMD (5) is controlled while the polarized states of the light beams produced by the polarization split by means of the PBS prism (71) are controlled. Thereby, a three-dimensionally viewable image and a high-resolution image created by pixel-offset can be projected. Since the relay optical system (61) is provided, the lens backs of the projection lenses (81) can be shortened, and the projection lenses (81) and further the projection optical system (6) can be made compact.

摘要： A projecting image display device is disclosed which includes a display and a micro lens array, where the pixels of the display and the micro lens elements each have non symmetric properties in length and width directions. The micro lens concentrates color-separated light onto pixels of a display device so that light does not hit the black matrix. By providing a display having pixels which are not equal in length and width, pixels corresponding to red (R), green (G) and blue (B) can be arranged in a substantially square area, and by providing a micro lens array which has non symmetric properties in length and width, the color separated light can be concentrated onto the non square display pixels.

摘要： In a projection-type display apparatus that directs light from a light source through the illumination optical system to a display panel so that an image displayed on the display panel illuminated by the light directed thereto is projected through a projection optical system onto a screen, an illumination optical system is used that has a light intensity uniformizing device of which the entrance surface is located at a first conjugate position substantially conjugate with the light source and of which the exit surface has a shape geometrically similar to the panel surface of the display panel and a reflection optical system for forming an image of the exit surface of the light intensity uniformizing device on the panel surface of the display panel. In the reflection optical system, every surface having an optical power is a reflective surface.

摘要： A rear projector for performing image projection includes: a screen and a projection optical system. The screen has a rotationally symmetric Fresnel lens. The projection optical system has at least one reflection surface formed of a rotationally asymmetric free curved surface. The projection optical system is nonaxisymmetric and makes a central principle ray incident obliquely on the screen in the image projection. The Fresnel lens has aberration that cancels out pupil aberration of the projection optical system so that principal rays of beams exiting from the Fresnel lens become substantially parallel to each other.

摘要： In a projection optical system for obliquely performing enlargement projection of an image formed on a display device surface onto a screen surface, a plurality of reflective surfaces are provided, at least one of which is a curved reflective surface having an optical power. Letting the curved reflective surface, out of said at least one curved reflective surface, having the largest effective optical region be the largest curved reflective surface, the reflective surface other than the largest curved reflective surface is slightly decentered with the largest curved reflective surface kept in a fixed state so as to perform pixel shift on the screen surface in a vertical direction, or a horizontal direction, or an oblique direction, or vertical and horizontal directions within the range of a pixel pitch.
