    摘要: An illumination apparatus includes; a first solid-state light source, a second solid-state light source, a first arrangement member provided with a first arrangement surface, a second arrangement member provided with a second arrangement surface, an optical unit configured to reduce a dispersion angle of a light beam. The first solid-state light source emits a light beam having a first directivity. The second solid-state light source emits a light beam having a second directivity greater than the first directivity. A distance from the second arrangement surface to the second light-entering surface is longer than a distance from the first arrangement surface to the first light-entering surface.

    摘要: The present invention relates to a fluorescent display tube suitable for use in a large screen display. The present invention enables the fluorescent segments R, G and B to be arranged at positions close to a peripheral side wall (13) of the tube (1) by, particularly, enlarging a range to which electron beams can impinge and eliminating the influence of electric field near the glass wall of the fluorescent display tube. Upon this, light emitting area can be increased to obtain bright display and distances between adjacent fluorescent segment R, G and B trios of adjacent fluorescent display tubes (1) and between adjacent trios in each fluorescent display tube (1) are made small to thereby shorten the arranging pitch of the fluorescent trios as a whole in a large screen display device, improving resolution.

    摘要: An illumination apparatus includes multiple liquid crystal panels, a polarization-state adjusting element, and a cross dichroic prism. A green component light includes a central-wavelength component light, a short-wavelength component light, and a long-wavelength component light. The polarization-state adjusting element separately adjusts a polarization state of the central-wavelength component light and each of polarization states of the long-wavelength component light and the short-wavelength component light.
