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： 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： In a reflection type display apparatus in which a forward lightening apparatus is arranged in front of a reflection type display panel, lowering of contrast occurred when the forward lightening apparatus is turned ON is prevented. In this reflection type display apparatus, the forward lightening apparatus is adhered via an adhesive layer to a front surface of the reflection type display panel having a reflection plane. The reflection plane is constituted by a large number of first very fine patterns having a spherical shape, and a large number of second very fine patterns whose front surfaces are inclined. External light which is vertically entered into the front surfaces is reflected by the first patterns, and thereafter, the reflected external light is projected as a display along a forward direction. The forward lightening apparatus is arranged by providing a light source on a side surface of a light conducting plate having a wedge shape. The light is obliquely projected from a rear surface of the light conducting plate to the reflection type display panel. The light which is obliquely projected from the forward lightening apparatus to the reflection type display panel is reflected by the second patterns, and thereafter, is projected along the substantially same directions as reflection light of the external light.

摘要： An image display device is so adapted as to eliminate image roughness while the resolution of the image is kept as high as possible. The image display device includes an image display body having a plurality of pixels arranged periodically in two dimensions and an optical low-pass filter placed on the front surface of the image display body. The spatial frequency of the initial minimum value of an modulation transfer function in one direction of the optical low-pass filter is decided by two basic frequency vectors M, N for sampling frequencies determined by the arrangement of pixels in the image display body, and the spatial frequency of the initial minimum value of the modulation transfer function in the other direction of the optical low-pass filter is decided by differences .+-.(N-M) between the basic frequency vectors.

摘要： The light emitted from a spot light source (45) is emitted at a linearly extending region by a wedge-like light conductor (47) and deflected by a prism sheet (50). This light is emitted in a direction perpendicular to a light incident surface (44a) of the light conductor plate (44) and has a directivity narrow in a widthwise direction of the light conductor plate (44). The light conductor plate (44) is formed, at its bottom surface, with a multiplicity of diffusion patterns (46) in a rectangular triangular form. The light reflected upon the diffusion pattern (46) is emitted perpendicularly to alight emitting surface (44b) of the light conductor plate (44). At this time, part of the light incident on the diffusion pattern (46) transmits through the diffusion pattern (46) whereby the directivity of emission light is narrowed in a lengthwise direction of the light conductor plate.

摘要： A color image display device has a light source which emits an approximately parallel beam of light, a color separation element for separating this parallel beam into beams of light of different colors, a liquid crystal display panel having picture elements and a lens array for focusing the separated beams at corresponding ones of these picture elements. The color separation element is formed with a prism array having two diffraction gratings on both sides of it such that a beam of white light passing through it will be separated into beams of different colors and the angles between the optical axes of these beams of different colors will be greater as they leave the separation element than if this beam of white light passed through only one of these diffraction gratings. Either one or both of these diffraction gratings may be integrally formed respectively on one or both of the surfaces of the prism array.
