A projection type image display apparatus in which shortening of the projection distance (widening of the angle of view) and miniaturization of the projection optic system are realized is provided. It comprises, in a traveling direction of the light, an image display element, a lens group including a plurality of lenses, a first lens, a second lens, and a mirror to reflect light emitted from the second lens to be projected obliquely on a screen in this order. The refractive power of the first lens is positive and the refractive power of the second lens is negative. The first and the second lenses are moved in an interlocked relationship with each other along an optical axis of the lens group and a movement amount of the first lens is made larger than a movement amount of the second lens.

The present invention provides a technology that makes it possible to display high-quality images by reducing a reflection loss of the image light entering the upper left and right ends of a transmissive screen. At the image generation source side of the Fresnel lens sheet, a totally reflective prism section (10) is provided that totally reflects incident rays of light and causes the light to exit toward the image-watching side. At the image-watching side of the Fresnel lens sheet (6), a refractive prism section (11) is also provided that refracts the light entering from the totally reflective prism section (10) and causes the light to exit toward the image-watching side. The refractive prism section (11) has a roughed refractive face.

A projection lens of the retrofocus type which has a long back focus, can project with a high contrast, exhibits small aberrations such as a distortion aberration and converts a light path in the inside thereof. A first lens set (0) having a negative refractive power and having light path conversion means built therein, an iris (400) and a second lens set (300) having a positive refractive power and including an aspheric lens are disposed in order from the screen side. The first lens set (0) includes a first A lens set (100) having a negative refractive power and including one or more aspheric lenses, a bending mirror (M) serving as the light path conversion means, and a first B lens set (200) having a positive refractive power. The lenses in the first A lens set have an outer shape with a portion thereof cut outside an effective light ray in a direction of the light path conversion, and the direction of the light path conversion is a direction of a shorter side of the rectangular image formation element. Where the focal length of the entire system is represented by FL, the back focus by FB, the front side focal position of the second lens set by FFP2, the distance between the iris and the second lens set by Dst, and the air converted distance on the optical axis between the first lens set and the second lens set by D2, conditional expressions [FB / FL>2.2], [0.59<|FFP2 / Dst|<0.96] and [3.75 G02B 13 / 04 G02B 13 / 18 G02B 13 / 22 25 24 0 2002 / 8 / 28 1549945 2004 / 11 / 24 1278160 2006 / 10 / 4 2006 / 10 / 4 2006 / 10 / 4 Sony Corp.

Both ends of a transparent cover which is formed of a curved member are fitted to a lens guard and a mirror guard, and a free-shaped surface mirror and a free-shaped surface lens are housed in a sealed space defined within a projection type image display device.

A total reflecting prism portion is formed on an image generation source side of a Fresnel lens sheet which constitutes a rear projection type screen. The total reflecting prism portion is formed in an area in which the angle of incidence of a projection image projected from an optical part on the Fresnel lens sheet is at least about 40·. The total reflecting prism portion causes incident light to be outputted as output light at a predetermined output angle by a total reflection phenomenon after a first refraction phenomenon. A refracting prism portion is formed on an image monitoring side of the Fresnel lens sheet. The refracting prism portion is formed in an area opposed to the portion where the total reflecting prism portion is not formed. The refracting prism portion causes incident light to be outputted as output light at a predetermined output angle by a second refraction phenomenon.

A rear projection-type display device has a Fresnel lens sheet where a lens pattern having a Fresnel surface as a light ray transmissive surface and a rise surface as a non-light ray transmissive surface are concentrically formed and where the optical axis, the center of the lens pattern, of a Fresnel lens is positioned outside the Fresnel lens sheet; a transmission screen having a light diffusion plate; a projector capable of projecting an image on the transmission screen; and a reflection mirror provided between the projector and the transmission screen. The reflection mirror is installed at a substantially middle position between the projector and the transmission screen.
