A plurality of deflection patterns are formed in a surface facing a light outgoing plane of the light guide plate, the deflection pattern includes an inclined plane facing the light source side and a re-incident plane substantially perpendicular to the light outgoing plane. Light from the light source is reflected by the inclined plane and outputted from the light outgoing plane to the LCD. A tilt angle (α) of the inclined plane satisfies: 45°−[Sin−1(Sin θ/n)]/2≦α≦45°+[Sin−1(Sin θ/n)]/2, wherein θ is an angle between a direction of peak brightness of outputted light and a direction perpendicular to the light outgoing plane, n is a refractive index of the light guide plate, and θ is within 6-15°.

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： 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.
