Claim 11:
12. The method according to claim 11, wherein forming the conductive pattern on the substrate by the one-time patterning process comprises:
sequentially forming a first conductive film, a second conductive film, and a third conductive film on the substrate;
forming a first photoresist pattern on the third conductive film;
acquiring a first conductive sub-pattern by performing a first etching process on the third conductive film;
acquiring a second conductive sub-pattern by performing a second etching process on the second conductive film;
acquiring a second photoresist pattern by performing an ashing process on the first photoresist pattern to remove an edge portion in the first photoresist pattern;
acquiring a third conductive sub-pattern by performing a third etching process on the first conductive sub-pattern, wherein the third conductive sub-pattern comprises the second protective electrode;
acquiring a fourth conductive sub-pattern by performing a fourth etching process on the first conductive film, wherein the fourth conductive sub-pattern comprises the first protective electrode; and
acquiring a fifth conductive sub-pattern by performing an over-etching process on the second conductive sub-pattern, wherein the fifth conductive sub-pattern comprises the metal electrode.
