Semi-transmissive/semi-reflective electrode substrate, method for manufacturing same, and liquid crystal display using such semi-transmissive/semi-reflective electrode substrate

A semi-transmitting and semi-reflecting electrode substrate comprising:

• a transparent substrate;
• a transparent conductive layer which is disposed on said transparent substrate and contains indium oxide as its major component and further one or two or more oxides selected from tungsten oxide, molybdenum oxide and niobium oxide;
• a TFT element disposed on said transparent substrate:
• and
• a metal layer which is disposed on said transparent substrate and connects said transparent conductive layer electrically with said TFT element;
• wherein:
• said metal layer has a reflectance of 80% or more,
• wherein the value of [In]/[All metals] that is a composition ratio of In in said transparent conductive layer containing indium oxide as its major component and further one or two or more oxides selected from tungsten oxide, molybdenum oxide and niobium oxide is 0.85 to 0.99.

A semi-transmitting and semi-reflecting electrode substrate comprising:

• a transparent substrate;
• a transparent conductive layer which is disposed on said transparent substrate and contains indium oxide as its major component and further one or two or more oxides selected from lanthanoid-based metal oxides;
• and
• a metal reflecting layer which is disposed on said transparent substrate and is connected electrically with said transparent conductive layer,
• wherein the value of [In]/[All metals] that is a composition ratio of In in said transparent conductive layer containing indium oxide as its major component and further one or two or more oxides selected from lanthanoid-based metal oxides is 0.8 to 0.99.
