    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： An ion wind generator is arranged in the vicinity of a light source. The ion wind generator allows an air flow by negatively ionizing air by corona discharges using negative side needle electrodes, and drawing the negatively-ionized air using a ground side mesh electrode. High-temperature air surrounding the light source is drawn by the air flow and exhausted from an exhaust port at a rear side of a casing. An ozone decomposition catalyst filter is provided in the exhaust port. Ozone (O3) is generated by the corona discharges in the ion wind generator. However, the ozone is decomposed by passing through the ozone decomposition catalyst filter provided at the exhaust port.

    摘要： The auxiliary light source has LED chips respectively emitting red lights arranged therein in an array shape, and has lens cells for parallelizing light arranged therein on the light exit side of the LED chips, for example. The LED chip is arranged in correspondence with each of lenses composing a pair of fly's eye lenses, and the pair of lenses introduces the light emitted from the LED chip into the whole surfaces of liquid crystal panels. A mixing mirror transmits white light emitted from a main light source and reflects light emitted from the auxiliary light source, and mixes the white light and the auxiliary light respectively emitted from both the light sources and introduces the mixed lights into the pair of fly's eye lenses.

    摘要： A projection lens unit and a projection mirror unit are moved relative to an illumination optical system, between a first position where an image is projected in a shape that is longer along a direction of projection onto a projection plane and a second position where an image is projected in a shape that is longer along a direction perpendicular to the direction of projection onto the projection plane. When the projection lens unit and the projection mirror unit are located in the first position, a vertically long image is projected onto the projection plane (portrait display). In this state, when the projection lens unit and the projection mirror unit are moved to the second position, a horizontally long image is projected onto the projection plane (landscape display).
