Patent number: 6605834Abstract: An upper dielectric layer in a plasma display panel that is capable of enlarging an insulation intensity as well as improving a dielectric constant. In the upper dielectric layer, a ferrodielectric thin film and a dielectric thick film are provided. Since the upper dielectric layer uses a ferrodielectric thin film with a high temperature stability made by a vacuum vapor deposition technique, it can minimize a chemical reaction to electrodes and a generation of bubble to keep a stable discharge characteristic. Also, it can enlarge a capacitance value to reduce a discharge voltage.Type: GrantFiled: February 7, 2000Date of Patent: August 12, 2003Assignee: LG Electronics Inc.Inventor: Yoon Kwan Lee
