摘要： A projection display device comprising three projection lenses arranged in a row in a side by side relationship and having respective optical axes extending toward a screen, and three liquid crystal display panels forming images of red, green and blue color lights, the liquid crystal display panels and the projection lenses being arranged to form sets individually. A mirror is arranged between the display element and the projection lens of at least one of the sets. Accordingly, one of the display elements is arranged so as to face in a first direction and the adjacent display element so as to face in a second direction. It is thus possible to reduce the distance between the adjacent projection lenses even if the size of the liquid crystal display panels is enlarged.

摘要： A light source for use in a projection type liquid crystal display device. The light source includes an electrodeless light emitting member having a light emitting material sealed in a transparent tube to emit light upon the application of microwave electromagnetic energy. A concave mirror is arranged on the outside of the light emitting member, and the transparent tube is supported by a rotatable rod-like support member which extends through the concave mirror. Means in the form of a vane, a screw or a projection is arranged on the rod-like support member or on the light emitting member for stirring air, while the rod-like support member rotates, to cool the light emitting member.

摘要： A lens array 22C has convex lenses 221 and 221C arranged in alternate and staggering manner to one another. In combination with a condenser lens 23, the convex lenses 221 form images of respective convex lenses 211 of a lens array 21 on a plane 24 to be illuminated in overlapping so that an illuminance distribution on the plane 24 is almost uniform, while the convex lenses 221C whose focal length is longer than that of the convex lenses 211 make on the plane 24 an illuminance distribution of a mountain-shape. Flat plate portions and concave lenses may be employed instead of the convex lenses 221C. A polarization conversion element comprises two elements and an element disposed therebetween with its longitudinal direction being perpendicular to the two element. The images of a light emitting part are included in band-shaped useful incident areas. A polarization conversion section comprises a middle part which is thin but has a larger divergent angle and side parts each has a smaller divergent angle and a simpler construction but is thicker with its size larger.

摘要： The projection type display apparatus has liquid crystal panels with polarizers, a light source, a power supply, and a ballast. A cooling device is arranged in the apparatus such that a first set of cooling fans blow cooling air to cool the liquid crystal panels and the polarizers, and a second set of cooling fans suck the cooling air passing through the liquid crystal panels and the polarizers and blow the cooling air to independently cool the light source, the power supply, and the ballast. Therefore, a projection type display apparatus with little light leakage and low noise can be realized. The invention also provides a cooling unit, for the light source, which includes a movable lamp house and a duct with a cooling fan.

摘要： A projector comprising liquid crystal display panels and a projection lens for projecting the modulated light to a screen. A back surface reflection mirror including a transparent plastic sheet and a reflecting film is arranged between the projection lens and the screen. The mirror is thin and light and may have optical anisotropy. In order to eliminate an uneven pattern appearing in the screen caused by optical isotropy of the mirror and the difference between the light distribution characteristics in the screen for P- and S-polarized light, the projection lens and the back surface reflection mirror are arranged in such a relationship that a wave normal vector of an arbitrary component of the light projected by the projection lens and made incident to the back surface reflection mirror is not parallel to the optical axis of the plastic sheet.

摘要： The invention relates to a backlight unit for liquid crystal displays, etc.; and its object is to provide a backlight unit not involving the problem that the emitted light leaks out of the optical waveguide, even when the space around the cold-cathode tubes in the light source unit for it is filled with a liquid of which the refractive index is nearly the same as that of the glass material that forms the outer wall of the cold-cathode tubes. The backlight unit comprises a housing 6 which houses cold-cathode tubes 2, 4 therein and of which the inner surface is coated with a light reflector 10; a transparent liquid filled in the housing 6; and an optical waveguide 1 made of a transparent substance and having a light-emitting surface S. The reflective surface of the light reflector 10 has a cross-section profile of X-T-U-V-W-Y, on which the light emitted by the cold-cathode tubes 2, 4 is reflected, and the thus-reflected light is led to the light-emitting surface S of the optical waveguide 1 at an incident angle not smaller than the critical angle to the surface S.

摘要： The present invention relates to a projection type display using a transmission type liquid crystal light valve, and its object is to supply a projection type display capable of exhibiting a high quality gradation display by preventing a leak current at a switching device. The projection type display comprises three liquid crystal light valves 21R, 21G, and 21B which have polarizing plates 20Rp, 20Gp, and 20Bp, modulate in intensity and emit each light of color components of red, green, and blue, and a dichroic prism to synthesize exiting lights from respective light valves. The projection type display is structured to arrange half-wave plates 20Ri, and 20Gi between the liquid crystal light valves 21R, and 21G for red and green, to set a polarizing direction of an exiting light of a blue component orthogonal to polarizing directions of the other two exiting lights.
