    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： A display device includes a reflective type polarizer, a light valve, an analyzer, a mirror, and a polarization rotating film. The polarizer allows a first polarized light to pass therethrough and a second polarized light to be reflected thereby. The second polarized light is then reflected to the polarizer by the mirror, and the vibrating plane of the second polarized light is rotated by the polarization rotating film, so that the second polarized light can pass through the polarizer. The polarizer is inclined to an optical axis of the device. The mirror is arranged near the light source. This principle is also applied to a projection type color display device. In addition, a polarized light source including a lamp, a reflector, a polarizer, a mirror, and a polarization rotating film is disclosed.

    摘要： A lighting unit including a light-reflecting reflector, a plurality of cold cathode tubes disposed inside the reflector and an optical waveguide connected with an open end of the reflector to guide the light emitted by the cold-cathode tubes. The reflector has a reflective surface that reflects the light having been emitted by the cold-cathode tubes in the direction nearly perpendicular to the wall of each tube, and only in a direction in which the light reflected does not re-enter the cold-cathode tubes. In another embodiment, the lighting unit may include a second optical waveguide disposed in the space between the cold-cathode tube and the reflector, wherein a space is formed between the cold-cathode tube and the second optical waveguide.
