    摘要: A projection-type image display device includes a transmissive image display panel having a matrix of pixels arranged at different pitches in different directions perpendicular to each other, and a planar microlens array for converging light emitted by a light source onto the transmissive image display panel. The planar microlens array comprises a substrate and a matrix of microlenses disposed on the substrate for converging the light onto the pixels, respectively, each of the microlenses being of an oblong shape. Each of the microlenses may have a longitudinal axis inclined with respect to an axis of the matrix of pixels to cover the pixel aperture of one of the pixels. The oblong shape of each of the microlenses may be composed of a pair of spaced identical semicircles and a rectangle interconnecting the identical semicircles and having sides of the same length as the diameter of the semicircles. Since the oblong microlenses are shaped to fully cover the pixel apertures of the corresponding pixels, the light from the light source is efficiently converged onto the pixels by the microlenses to produce light display images.

    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: An image display apparatus is disclosed which includes: an optical system including a light source and at least one projection lens; a display means for forming a display image, the display means including a non-luminescent display panel and a microlens array disposed on the light-incidence side of the display panel; and at least one projection lens for projecting the display image; wherein the display panel and the microlens array are combined with each other by means of an adhesive made of a transparent material. In cases where the microlens array is provided with color filters which are arranged so as to correspond to the microlenses of this array, the image display apparatus can provide a bright display of color images with an improved contrast. Moreover, when the display panel and the microlens array are combined with each other by means of an adhesive containing spacers, the image display apparatus has a high thermal reliability.

    摘要: Disclosed is a liquid crystal display device which comprises first and second transparent substrates disposed one above the other, and a liquid crystal layer disposed therebetween and having pixels. The second transparent substrate includes a microlens array therein, which has microlenses for converging light on the respective pixels. The microlenses are so positioned that their focal points are located in the vicinity of the inner surface of the second transparent substrate, which is the surface on the side provided with the liquid crystal layer. Since the microlens array is included in one of the two transparent substrates, the focal length of each microlens can be made shorter, resulting in an improved effective aperture ratio.
