摘要： An illumination apparatus includes a red light valve, a green light valve, a blue light valve, a polarization adjustment element, and a color combiner. The polarization adjustment element adjusts polarization of fourth color component light. The color combiner combines light emitted from the red light valve, the green light valve and the blue light valve. Superimposed component light which is any one of a red component light, a green component light and a blue component light enters the polarization adjustment element together with a fourth color component light. The polarization adjustment element transmits the superimposed component light without adjusting the polarization, and transmits the fourth color component light with adjusting the polarization. The superimposed component light and the fourth color component light emitted from the polarization adjustment element enter a specific light valve corresponding to the superimposed component light, among the red light valve, the green light valve and the blue light valve.

摘要： An illumination apparatus includes a plate-like separation optical element having a dichroic surface and a PBS surface. The dichroic surface reflects green component light and transmits yellow component light. The PBS surface transmits P polarization component light and reflects S polarization component light. The separation optical element combines red component light entering from a certain direction and transmitted through the dichroic surface, with yellow component light entering from a different direction and reflected by the PBS surface, and leads a combined light towards a red liquid crystal panel. The separation optical element combines green component light entering from the certain direction and reflected by the dichroic surface, with yellow component light entering from the different direction and transmitted through the PBS surface, and leads a combined light towards a green liquid crystal panel.

摘要： An image signal storing unit stores an image signal provided from the outside. An image processing unit appropriately processes the image signal stored in the image signal storing unit in accordance with the instruction from an adjusting unit. A projecting unit projects, onto a display area, light corresponding to an image created by the image processing unit. A display size determination unit computes the display size of the picture plane displayed on a screen based on an image captured by the camera provided adjacent to the projection-type video-image display device. The display size determination unit then determines whether or not the display size of the picture plane is equal to or larger than a predetermined upper-limit size.

摘要： An illuminating device includes a discharge lamp, a condenser lens, an integrator lens, a polarization conversion system, an electromagnetic wave shielding plate, and an electromagnetic wave shielding wall. A light given out from each lens in the light-incident-side fly's eye lens becomes two light fluxes via respective polarizing beam splitters and the two light fluxes pass through two lenses in the light-exit-side fly's eye lens. The electromagnetic shielding plate has an aperture on an optical axis of each lens in the light-exit-side fly's eye lens. The electromagnetic wave shielding plate is grounded through the electromagnetic wave shielding wall.

摘要： An ion wind generator (20) is arranged on one side of a light source (1). The ion wind generator (20) produces an air current by negatively ionizing air by corona discharges at a needle electrode (21), or negative side, and drawing the negatively-ionized air at a cylindrical electrode (22), or positive side. The air current blows toward the light source (1) and removes heat generated by the light source (1). An ultraviolet ray from the light source (1) is introduced to a vent of the ion wind generator (20) by a first dichroic mirror (4) and a ultraviolet ray reflection mirror (17). Though air exhausted from the vent includes ozone (o3) produced by corona discharges, the ozone is decomposed by the ultraviolet ray.

摘要： A reflection mixing member (13) has an alignment in which light from a first light source is incident on a reflecting surface (13a) and light from a second light source is incident on a reflecting surface (13b). A relationship between a pitch Wp, which is a pitch between portions (triangular prisms) respectively formed of the reflecting surface (13a) and the reflecting surface (13b) in the reflection mixing member (13), and a lens pitch Wf is set to be (Wp/Wf≠1). As a result, light fluxes of respectively different distribution are incident on each lens portion of fly's eye lens 14a, so that it is possible to prevent luminance non-uniformity in light incident on a liquid crystal display panel (5) from being generated and prevent color non-uniformity from being generated on a screen at the same time.
