摘要： According to a front light comprising an optical waveguide 25 and a light source 24 arranged on the side of the optical waveguide 25, the optical waveguide 25 comprises a light input surface and light emission surface 28, and a plurality of deflection patterns 26 are formed on the surface opposed to the light emission surface 28. Light from the light source 24 is input from the light input surface of the optical waveguide 25 and propagated in the optical waveguide 25. The light totally reflected by the deflection patterns 26 among the light propagated in the optical waveguide 25 is emitted from the light emission surface 28 in the direction oblique to the normal direction of the light emission surface 28. The light is emitted from the light emission surface 28 so as to be aligned in one direction regardless of its position.

摘要： A method for manufacturing an optical device is disclosed. The method includes coating a substrate with a resin thin layer, wherein temperature of the resin thin layer is controlled lower than a polymerization reaction starting temperature thereof and the resin is not substantially polymerized, heating the resin thin layer to a temperature higher than polymerization reaction starting temperature and glass-transition temperature but lower than a thermal decomposition starting temperature of the resin so that the resin thin layer is polymerized on the substrate to form a resin thin film thereon, pressing a stamp having an inverted micro-asperity pattern against the resin thin film such that a micro-asperity pattern is formed on a surface of the resin thin film; cooling the resin thin film to a temperature lower than the glass-transition temperature; and separating the stamp from the resin thin film.

摘要： Unit reflection areas (13) each consisting of one or plural recesses and projections (17) are formed on the surface of a reflection plate (11). Light incident into the reflection plate (11) and reflected by respective unit reflection areas (13) is emitted to the entire specified plane area (emission area (14)) established on a specified plane, which is like a band: ring. The emission area (14) is established so that overlap thereof with a shining area of light regularly reflected by a liquid crystal panel (18) is made slight. With such a construction, in a reflection plate that is used for a reflection type or semi-transmission type display device, light that is reflected in useless directions, is reduced, and light utilization efficiency of incident light-can be increased.

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： There is provided a manufacturing method of an optical device having a micro-asperity pattern that has various kinds of accurate three-dimensional shapes and is realized as thin films. A substrate is coated with a resin thin film made of a photosensitive resin, and the temperature of the resin thin film is controlled so as to be lower than the photosensitivity extinction temperature of the resin thin film. A micro-asperity pattern of a stamper is pressed against the resin thin film when the resin thin film is in a softened or melted state by pressurizing means, whereby a micro-asperity pattern is formed on the surface of the resin thin film.
