Abstract
The present invention provides a reflective liquid crystal display (LCD) apparatus including a glass substrate , a transparent electrode arranged on the glass substrate, a glass substrate , a thin film transistor (TFT) arranged on the glass substrate , an insulation film arranged on the TFT and having a convex/concave structure on its surface, a reflection electrode arranged along the convex/concave structure and connected to the TFT , and a liquid crystal layer sandwiched between the transparent electrode and the reflection electrode . The insulation film protects the TFT transistor after being formed and has the convex/concave structure 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.
