  • Patent number: 7602461
    Abstract: There is provided a method of manufacturing a diffusing reflector which assures high diffusion efficiency and excellent reflection characteristic for the lighting. First, a resin film having photosensitivity is formed on a substrate 2. Next, gathering of pillar-shaped bodies isolated each other by the patterning of resin film with the photolithography is provided. Subsequently, the uneven surface layer having the maximum inclination angle under 12° is formed by gently deforming individual pillar-shaped bodies with the heat treatment. Moreover, the gently deformed uneven surface layer is coated with the resin and the flat openings between pillar-shaped bodies arranged discretely are buried to ease the inclination angle. Finally, a metal film 13 formed on the gently deformed uneven surface layer.

  • Publication number: 20010022636
    Abstract: A reflective display device includes a panel, a light guide plate and a light source. The panel is provided with a transparent first substrate lying on the side of the external incident light, a second substrate joined to the first substrate with a predetermined gap therebetween and lying on the reflection side, a guest-host liquid crystal layer held in the gap between the substrates, and electrodes provided on each substrate for applying a voltage to the guest-host liquid crystal layer. The light guide plate is composed of a transparent material and is arranged on the outside of the first substrate. The light source is arranged on the end of the light guide plate and generates illumination light as required. The light guide plate normally transmits external light onto the first substrate and emits the external light reflected from the second substrate, and also, as required, guides illumination light onto the first substrate and emits the illumination light reflected from the second substrate.
