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 reflector is used in a display device and is disposed parallel to a predetermined plane, and has plural unit reflecting portions each having a reflection face for reflecting incident light in a direction different from that of regular reflection light of the predetermined plane. Further, the distance between a first tangential plane abutting on a first reflection face arranged in an arbitrarily extracted first unit reflecting portion at a reference point arranged in an arbitrary position on the first reflection face, and a second tangential plane abutting on a second reflection face arranged in a second unit reflecting portion adjacent to the first unit reflecting portion in parallel with the first tangential plane is preferably half or more of a coherent length of the incident light.

    摘要： A surface light source device includes a light guide plate having a light outgoing plane in one principal plane thereof; and a light source facing one end face of the light guide plate. A plurality of deflection patterns are formed in a surface facing the light outgoing plane of the light guide plate, the deflection pattern including an inclined plane located on a light source side and a re-incident plane substantially perpendicular to the light outgoing plane. Light emitted by the light source into the light guide plate is reflected by the inclined plane and then the light is outputted from the light outgoing plane. A tilt angle (α) of the inclined plane satisfies: 45°−[arc sin(sin θ/n)]/2≦α≦45°+[arc sin(sin θ/n)]/2, wherein θ is an angle formed between a direction of the peak brightness of the light outputted from the light outgoing plane and a direction perpendicular to the light outgoing plane, and n is a refractive index of the light guide plate, and wherein θ is within the range 6-15 degrees.

    摘要： A metal die having a reverse pattern of a irregular surface in which a height of a convex increases from the center toward the outer periphery is pressed onto a surface of a molding resin on a substrate. A total volume of convexes protruding from a cutting plane and a total volume of concaves depressed below the cutting plane coincide with each other over all of the metal die as a whole, so that it is possible to form the irregular surface on a reflective plane with good precision. A reflective film such as an aluminum film is provided on a surface of an uneven layer formed in such a manner, thereby obtaining a reflective plate having high light-collecting performance in a direction toward the center. As a result, it is possible to provide a reflective plate capable of collecting reflected light in a specified direction and of being formed with good precision by embossing, a method of making same, and a reflective type liquid crystal display having the reflective plate.
