Abstract:
A reflective liquid crystal display (LCD) apparatus comprising:a transparent first substrate; a transparent electrode arranged on the first substrate; a second substrate; a switching element arranged on the second substrate; an insulation film arranged on the switching element and having a convex/concave structure; a reflection electrode arranged on the insulating film along the convex/concave structure and connected to the switching element; and a liquid crystal layer sandwiched between the transparent electrode of the first substrate and the reflection electrode of the second substrate; wherein the insulation film protects the switching element; the convex/concave structure is formed by irregular arrangement of regions having different thickness values; and at least one portion of the insulation film is a single material that extends laterally along the second substrate under the entirety of at least two adjacent convex portions of the convex/concave structure, the at least one portion of the insulation film has, along its length, a generally constant thickness extending at least from an uppermost surface of an insulation layer of the switching element to a lowermost surface of a concave portion of the convex/concave structure located between the at least two adjacent convex portions; and the at least two adjacent convex portions of the convex/concave structure are formed in a continuous line shape.
