Abstract: PURPOSE: A liquid crystal display and a method of manufacturing the same are provided to prevent the defectives of metal film for data bus line. CONSTITUTION: A metal film(20) for data bus line comprises a first Mo film(15), an Al film(16), an Al2O3(aluminium oxide) film(17) and a second Mo film(18). The Al2O3 film(17) has a low etching speed against an etching solution or an etching gas and doesn't affect the conductivity of a data bus line. On etching process for exposing a drain electrode, the Al3O3 film(17) prevents the wet etching solution for etching a passivation from permeating into the Al film(16). Thereby, it is possible to prevent the short of the data bus line. The Al2O3 film(17) decreases the etching speed difference between the second Mo film(18) and the Al film(16). Thereby, it is possible to prevent the tip of the second Mo film(18).
