ABSTRACT:
A reflection type liquid crystal display comprises a first substrate including a rough portion formed on a surface thereof and a reflection electrode formed on the rough portion; a second substrate including a counter electrode formed thereon; and a liquid crystal layer interposed between the first and second substrates, driven by the reflection electrode and the counter electrode to perform a display. The reflection electrode is made of aluminum or aluminum alloy, and the reflection electrode includes surface oxidation layer having at least 5 nm thickness. The first substrate includes a vertical alignment film made of insulating material formed on the surface oxidation layer of the reflection electrode.
