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.

A method for producing a reflection type liquid crystal display comprising:
- a first substrate including a rough portion formed on a surface thereof, a reflection electrode formed on the rough portion, the reflection electrode including a surface oxidation layer, and a vertical alignment film made of insulating material formed on the surface oxidation layer;
- 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 method including the steps of:
- pattering the reflection electrode from a thin metallic film made of aluminum or aluminum alloy which is formed on the first substrate covering the rough portion;
- oxidizing a surface of the reflection electrode whereby forming a surface oxidation layer having a thickness of at least 5 nm;
- applying vertical alignment film material at least on the surface oxidation layer;
- and
- heating and curing the vertical alignment film material whereby forming the vertical alignment film.
A method for producing a reflection type liquid crystal display comprising:
- a first substrate including a rough portion formed on a surface thereof, a reflection electrode formed on the rough portion, an oxide film formed on the reflection electrode, and a vertical alignment film made of insulating material formed on the oxide film;
- 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 method including the steps of:
- pattering the reflection electrode from a thin metallic film made of aluminum or aluminum alloy which is formed on the first substrate covering the rough portion;
- forming an oxide film on the first substrate so as to cover the reflection electrode;
- applying vertical alignment film material on the oxidized film;
- and
