摘要:
A pixel electrode employs a transparent electrode made from indium-zinc-oxide (IZO) that is capable of preventing damage and bending thereof. In a liquid crystal display device containing pixel electrodes, the transparent electrode is made from indium-zinc-oxide (IZO) having an amorphous structure so that it can be etched within a short period of time with a low concentration of etchant. Accordingly, it is possible to prevent damage and bending of the transparent electrode upon the patterning thereof.
