Liquid crystal display apparatus with protective insulating film for switching element and production method thereof

A liquid crystal display (LCD) apparatus comprising:

• a pair of a first substrate and a second substrate, each of which is transparent and is separately arranged so as to have a predetermined distance between each other;
• a transparent electrode arranged on the first substrate;
• a switching element arranged on the second substrate;
• an insulation film which is arranged on the second substrate in a continuous face shape and arranged on an upper part of the switching element so as to protect the switching element by overlaying the same, having a convex/concave structure on a surface facing the first substrate;
• a reflection electrode which is arranged on the insulation film and a surface of which, facing the first substrate, has a shape reflecting the convex/concave structure of the insulation film;
• and
• a liquid crystal layer filled in a space between the transparent electrode of the first substrate and the reflection electrode of the second substrate, wherein
• 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.
