Abstract:
A reflector for a reflection-type LCD device is provided, which reflects efficiently incident light to the viewer's side and that suppresses the change of color tone. The reflector comprises a roughened surface having a protrusion pattern. The protrusion pattern gives inclination angle to the surface according to a specific distribution where a first component with an inclination angle value of 0null is 15% or less in area and a second component with an inclination angle value from 2null to 10null is 50% or greater in area. The protrusion pattern gives a variation range of chromaticity coordinates (x, y) on a chromaticity diagram dependent on an angle of view. The variation range is limited in a circle on the chromaticity diagram. The circle has a radius of approximately 0.05 and a center at a point corresponding to white color.
