    摘要： A reflective plate is offered which is capable of forming an exit region of reflected light in an effective field of view area in an obliquely above or below position. The reflective plate has plural reflective subregions each having reflective surfaces for reflecting light. Light rays reflected from the reflective subregions form plural spreads of exit which intersect each other at a given upper position to thereby form a common exit region. The reflective subregions are so arranged that light entering the reflective plate from a vertical direction is reflected by the reflective subregions substantially toward the center of the exit region lying outside a region that is vertically above the reflective plate. The centers of the intensities of the reflected light rays concentrate at the center of the exit region.

    摘要： A first prism array (34) formed on a prism array plate (32) is arranged so as to confront a second prism array (37) formed on a prism array plate (35). When a light ray (r) that is parallel to an optical axis is transmitted through the first prism array, the light ray r enters into the second prism array (37) while refracted. The light ray that has been refracted by the second prism array (37) becomes an original light ray (r) that is parallel to the optical axis. Therefore, the light ray (r) that has passed through an optical path converting optical element (31) becomes a light ray (r) that is shifted in a direction perpendicular to the optical axis. As a result, the light is split and shuffled by the first prism array (34), so that a luminous intensity distribution thereof is uniformed.

    摘要： In a liquid crystal display device having an optical low-pass filter provided on a display screen, the optical low-pass filter is fixed to a liquid-crystal panel or a polarizing plate through a bonding layer having a refractive index different from the refractive index of the optical low-pass filter in a state where a surface having an optical function of the optical low-pass filter is directed toward a liquid-crystal panel or the polarizing plate. Further, in a liquid crystal display device having a phase plate, an optical low-pass filter is integrally formed on a phase plate. The occurrence of rainbow-shaped interference fringes is prevented. A liquid crystal display device is miniaturized and the number of components thereof is reduced. The fabrication precision of an optical low-pass filter is improved.

    摘要： A method of manufacturing a lens array according to the invention is presented wherein a first array of first lens-base elements is formed on a substrate with spacing therebetween. The first lens-base elements are heated so that the first lens-base elements melt to form first lenses having round surfaces. A separation layer is formed to cover the first lenses and the substrate. A second array of second lens-base elements is formed, the second lens-base elements being placed on a region where the first lenses are not formed so as to partly overlap with the first lenses. The second lens-base elements are also heated so that the second lens-base elements melt to form second lenses having round surfaces. The lens array comprises the substrate and the first and second lenses.

    摘要： The present invention discloses an opposed substrate for use in a liquid crystal display element, for example. The opposed substrate is constructed by a transparent substrate, microlenses formed on the substrate, a bonding layer, and cover glass. An alignment film and transparent electrodes are formed on the cover glass. The microlenses and the bonding layer are formed by selected resins which have thermal resistance to high temperatures not lower than 150.degree. C., permit heating treatment for forming the alignment film, and satisfy the difference in the refractive indexes between the resins, .increment.n.gtoreq.0.1, so as to enable the microlenses to have a numerical aperture not lower than 0.1. It is thus possible to prevent the decomposition of resins and separation of the microlens in heat treatment and to provide a high-quality, highly reliable liquid crystal display element.
