Abstract
A reflective liquid crystal display device including a first substrate and a second substrate, a liquid crystal layer interposed between the first and second substrates, a polarizing plate, and a reflection layer; wherein the polarizing plate and the reflection layer are located on opposite sides of the liquid crystal layer. A surface of the reflection layer reflecting light has projections, and an occupation of an area of portions where a tilt angle of a tangent line drawn against a profile of the surface with the projections is less than 2.degree. in a total area of the surface is in a range of 20% to 60%.

A reflective liquid crystal display device including a first substrate and a second substrate, a liquid crystal layer interposed between the first and second substrates, a polarizing plate, and a reflection layer;
- wherein the polarizing plate and the reflection layer are located on opposite sides of the liquid crystal layer, and
- further wherein a surface of the reflection layer reflecting light has projections, and flat portions, the flat portions being areas where a tilt angle of a tangent line drawn against a profile of the surface with the projections is less than 2.degree., in the flat portions occupying in a 20% to 60% of the total surface area of the surface.
A reflector for reflecting light, wherein a surface of the reflector reflecting light has projections and flat portions, the flat portions being areas of the surface where a tilt angle of a tangent line drawn against a profile of the surface with the projections is less than 2.degree., the flat portions occupying 20% to 60% of the total surface area of the surface.
