Abstract
A method of fabricating a liquid crystal display array substrate includes forming a gate wiring line having a gate pad electrode, forming a data wiring line having a data pad electrode, forming a protection layer over the gate pad electrode and the data pad electrode, and positioning etching tapes on the protection layer over the gate pad electrode and the data pad electrode.
Claims3
An etching tape for fabricating an array substrate for a liquid crystal display comprising:
- a base sheet;
- and
- an etching material layer formed on an entire surface of the base sheet, wherein the etching material is a gel type NH4HF capable of etching SiNx, wherein the base sheet is one of a cellophane film, a polymer resin film, or a steel use stainless film.
