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： A lens array wheel 4 receives light irradiated in a direction parallel to its rotation axis, to cyclically deflect the light. On each of liquid crystal display panels 7R, 7G, and 7B, the light is circularly scrolled, the effect of substantial intermittent illumination is produced, and hold blurring is reduced. A panel driver 15 starts to feed a pixel-driving signal in the succeeding frame to a pixel existing at a position, through which an illuminating area passes, on each of the liquid crystal display panels 7R, 7G, and 7B.

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 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： To provide a projection type video display capable of reliably preventing a double image from being produced. A first light flux producer for producing a first light flux and a second light flux producer for producing a second light flux are arranged on the light emission side of a lamp. The light flux producer comprises a condenser lens, a rod integrator, and a pair of lenses. Lights passing through the pair of lenses are respectively refracted by condenser lenses, and are respectively introduced into first and second areas of a liquid crystal display panel in such a manner as to cross an optical surface in a color separating and mixing sector.

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.
