摘要： A liquid-crystal display device has a planar microlens array and a liquid-crystal display panel coupled with the planar microlens array. The planar microlens array comprises an array of convex microlenses provided on a surface of a base glass plate. The array of convex microlenses is made of an ultraviolet-curable synthetic resin having a relatively high refractive index. A cover glass plate is joined to the liquid-crystal display panel and has a peripheral edge bonded to a peripheral edge of the array of convex microlenses. The cover glass plate is spaced from the array of convex microlenses by a hermetically sealed space which is filled with an inactive gas such as dry nitrogen gas, argon gas, or the like. The surfaces of the convex microlenses may be coated with an anti-oxidation film.

摘要： A microlens array of high converging efficiency is provided, independently of the array and lens filling rate of microlens arrays, with a method of manufacturing microlens arrays using the diffusion process. A multitude of refractive-index distribution type microlenses formed by diffusing in a planar transparent substrate a substance contributing to increasing the refractive index of the substrate are two-dimensionally and regularly arranged on the surface of the substrate. The microlenses are densely arranged on the surface of the substrate, and diffusion fronts of the microlenses form regions where the diffusion fronts are fused with those of the adjoining microlenses. The length of a region where certain two adjoining microlenses are fused together, in the direction of a straight line connecting the centers of the two microlenses is less than 20% of the array pitch of the microlenses in the above-mentioned direction.

摘要： The improved illuminating apparatus comprises a spheroidal mirror, a light source, a spherical mirror and a condenser lens. The spheroidal mirror has such a shape that it is deficient of a portion that would otherwise reflect light that illuminates any portions other than the object to be illuminated, and that the light from the light source which is directed toward said missing portion is reflected by the spherical mirror positioned on the rear side of said missing portion as seen from the light source and makes another reflection by that part of the spheroidal mirror which faces away said missing portion, thereby illuminating the object. The light source is positioned at the first focal point of the spheroidal mirror in such a way that it faces the mirror, and the spherical mirror is positioned in such a way that its reflecting face lies at the second focal point of the spheroidal mirror. An open window for the exit of light beams is provided in the spherical mirror at a position near the second focal point of the spheroidal mirror, and the condenser lens is provided further ahead of the open window (closer to the object to be illuminated).
