    摘要： The lighting device is equipped with a light guide having a linear Fresnel reflection surface consisting of steps of continuously alternating reflecting surfaces having two different reflection angles. A light source is installed at one end of the light guide of the above construction so that the light from the light source is emitted from the irradiation surface of the light guide after being reflected by the linear Fresnel reflection surface.

    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.

    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： Numerous photoelectric translation cells are arranged to correspond to associated picture elements in an active type matrix LCD display system. When a light pen is used as an input means, the system allows detection of light beam positions, enabling it to function as an input means.The liquid crystal input/output system constructed in this manner has advantages of low power consumption and thin and lightweight construction as compared with conventional input/output systems using a combination of CRT and light pen. It is best suited for applications in portable electronic appliances and offers great technical benefit by arranging the photoelectric translation cells in a manner so as to increase the aperture ratio of the matrix display.

    摘要： A light source device emits light for positional alignment and light for adhesion toward the optical devices. A position detecting device receives the light for positional alignment from the optical devices and optically detects a positional displacement of the optical devices. A positional alignment mechanism moves the optical devices with respect to each other in accordance with a detecting result of the position detecting device, thereby positionally aligning the optical devices. After the optical devices are positionally aligned, the light for adhesion is radiated to a photo-curing adhesive resin interposed between the optical devices, thereby adhering the optical devices.
