Publication number: 20030020404Abstract: A method of fabricating a plasma display panel and a front plate of the plasma display panel are disclosed. The first step of the method is to provide a front glass substrate having a pixel area and a bonding area. Next, an electrode, which has a pixel electrode positioned at the pixel area and a bonding electrode positioned at the bonding area, is formed on the front substrate. Then, a dielectric layer is formed over the pixel area and the bonding area to cover the pixel electrode and the bonding electrode, respectively. Thereafter, a rear plate is sealed to the front substrate by a sealing material so that the rear plate covers the pixel area without covering the bonding area. Then, the dielectric layer formed on the bonding area is removed to expose the bonding electrode.Type: ApplicationFiled: September 26, 2002Publication date: January 30, 2003Applicant: Acer Display Technology, Inc.Inventors: Yao-Ching Su, Wen-Fa Sung, Chun-Tang Peng
