Abstract
A liquid crystal display device comprises an optically diffusively reflecting layer arranged to maximize utilization of incident light. The reflecting layer contains a thin metallic film with projections () each having an unsymmetrical cross section to centralise reflected light in a specific azimuth direction (y). The range of viewing angles (θ, θ) into which a substantial portion of the incident light is reflected is broader in the specific azimuth direction (y) than in another direction (x). The director () of liquid crystal molecules initiallly lies in a plane (y-z) parallel to the specific azimuth direction (y) to achieve retardation self-compensation.
