Abstract
A method for forming an electrode in a plasma display panel, which simplify fabrication steps of a metal electrode and a transparent electrode and prevent bubbles from being generated due to reaction between the metal electrode and a dielectric layer, includes the steps of forming a metal oxide layer on a transparent substrate in a predetermined pattern, etching a surface of the metal oxide layer to form an uneven portion, and chemical plating a surface of the uneven portion to form a metal electrode.
Claims25
A structure of an electrode in a plasma display panel, comprising:
- a metal oxide layer comprising titanium oxide or zinc oxide formed on a transparent substrate;
- a metal electrode formed directly on a lower surface of the metal oxide layer in the same pattern;
- and
