Abstract:
A method of manufacturing a liquid crystal display including a substrate having a patterned metal layer, comprising:providing the substrate, wherein the patterned metal layer comprises at least one material selected from the group consisting of Mo, Ta, Ti, MoSi and TiSi, and the substrate further comprises a low resistance metal layer located under the patterned metal layer; forming an insulating layer on the substrate; and exposing at least one portion of the patterned metal layer by etching at least one portion of the insulating layer covering the patterned metal layer using at least one gas mixture selected from the group consisting of CF4+H2, CF4+H2+He, CF4+H2+N2, SF6+CHF3 and CF4+CHF3, wherein a volume ratio among components of said at least one gas mixture depends on an area of the insulating layer that is exposed.
