  • Reflector which appears bright when viewed at specific angle and reflective liquid crystal display
    Patent number: 6947107
    Abstract: A reflector for a liquid crystal display includes a substrate with light-reflective concave portions on the surface thereof. Each concave portion has a specific vertical section which passes through a deepest point of the concave portion. The internal shape of the specific vertical section is defined by a first curve, which extends from one point on the peripheral edge of the concave portion to the deepest point of the concave portion, and a second curve, which extends continuously from the first curve and from the deepest point of the concave portion to another point on the peripheral edge of the concave portion. The average of the absolute value of an inclination angle of the first curve relative to the substrate surface is larger than the average of the absolute value of an inclination angle of the second curve relative to the substrate surface.
