Claims20
A transparent conductive film comprising an indium oxide, a tin oxide and at least one lanthanoid metal oxide,
- the film containing the indium oxide in an amount of 70 atomic % to 95 atomic %,
- the film comprising a portion for connection to a conductor, and
- at least the connection portion having crystallinity.
A transparent conductive film comprising an indium oxide, a tin oxide and at least one lanthanoid metal oxide,
- the film comprising a portion for connection to a conductor, and
- at least the connection portion having crystallinity,
- wherein the lanthanoid metal oxide is a cerium oxide and/or a samarium oxide, and which film has the following metal component ratios in terms of atomic %,
- In/(In+Sn+Ce(and/or Sm))=0.6 to 0.969
- Sn/In+Sn+Ce(and/or Sm))=0.03 to 0.2 and
- Ce(and/or Sm)/(In+Sn+Ce(and/or Sm))=0.001 to 0.2.
