    摘要: A reflection-type liquid crystal display according to the invention includes two glass substrates, a transparent electrode provided on one glass substrate, an insulator film which is provided on another glass substrate and on which an uneven structure is formed, a reflecting electrode provided on the insulator film, and a liquid crystal layer sandwiched between a side of the transparent electrode and a side of the reflecting electrode. The insulator film includes a first insulating layer in which a large number of depressions isolated as surrounded by protrusions are irregularly arranged and a second insulating layer covering the insulating layer entirely. The protrusions are all connected in a network, so that if some of these protrusions have weaker adherence with an underlying layer, they can be supported by the surrounding protrusions.

The insulation film 48 protects the TFT transistor 44 after being formed and has the convex/concave structure 45a formed irregular arrangement of regions having different film thickness values. Thus, it is possible to prevent deterioration of the switching element during the production as well as to reduce the number of production steps.
