Abstract

A plasma display panel includes barrier ribs (130) disposed between a front substrate (111) and a rear substrate (121) and define discharge cells (180). Sustain electrode pairs are disposed on the front substrate. Address electrodes (122) are disposed on the rear substrate in a direction to cross the length direction of the sustain electrode pairs (112). A front dielectric layer (115) covers the sustain electrode pairs, and has grooves (190) formed in a direction parallel to the length direction of the sustain electrode pairs such that the grooves have slopes in a direction from the rear substrate towards the front substrate with ends of the sustain electrode pairs being located on a lower surface of the front substrate where shadows of the slopes are cast. A rear dielectric layer (125) covers the address electrodes. Phosphor layers are coated in the discharge cells and a discharge gas fills the discharge cells.

Description

technical field [0001] The present invention relates to a plasma display panel, and more particularly, to a plasma display panel which optimizes the structure between discharge electrodes and electrode positions, thereby increasing the ratio of the black portion in front of the panel, thereby Reduced reflection brightness viewed from the front of the panel. Background technique [0002] Recently, plasma display panels have attracted attention as a substitute for conventional cathode ray tube display devices. A plasma display panel is a flat display panel that displays a desired image using visible light emitted by exciting a phosphor material formed in a predetermined pattern with ultraviolet rays formed by filling thereon A discharge of discharge gas between two substrates with multiple electrodes is generated. [0003] 1 is a vertical sectional view of the structure of a conventional alternating current (AC) type plasma display panel 10. Referring to FIG. [0004] The c...
