[0052] figure 2 A plasma display panel according to a first embodiment of the present invention is illustrated.

[0053] Such as figure 2 As shown, the plasma display panel according to the first embodiment of the present invention includes a front panel 200 and a rear panel 210 connected to each other with a certain distance therebetween. Also, the plasma display panel includes: address electrodes 213 formed on the rear substrate 211 in a direction crossing the sustain electrode pairs 202 and 203; and barrier ribs 212 separating a plurality of discharge cells and formed on the front substrate. 201 and the rear substrate 211.

[0054] The front panel 200 includes the aforementioned sustain electrode pairs 202 and 203 disposed over the front substrate 201 . The sustain electrode pairs 202 and 203 are classified into scan electrodes 202 and sustain electrodes 203 depending on their functions, and a driving pulse for each of the scan electrodes 202 and the sustain electrodes...

Abstract

A plasma display panel is provided. Particularly, an embodiment of the present invention suggests a sustain electrode structure comprising opaque electrodes instead of transparent electrodes to improve an aperture ratio. The number of electrode lines pertained to each sustain electrode is suggested to improve the aperture ratio, and a first projection electrode projecting to a central portion of a discharge cell from the electrode line can allows a discharge initiation voltage level to be decreased. A second projection electrode projecting in a direction away from the central portion of the discharge cell can be advantageous of increasing discharge diffusion efficiency within the discharge cell.

Description

technical field [0001] The present invention relates to display devices, and more particularly, to plasma display panels. Background technique [0002] In a typical plasma display panel, barrier ribs formed between a front substrate and a rear substrate constitute a unit cell. Each unit cell is filled with a main discharge gas such as neon (Ne), helium (He), or a mixed gas of Ne and He and an inert gas containing a trace amount of xenon. When a discharge event occurs through a high voltage frequency, the inert gas generates vacuum ultraviolet rays and causes phosphors formed between barrier ribs to emit light to thereby realize an image. Such a plasma display panel can be configured to be thin and light, and thus it is attracting attention as a next-generation display device. [0003] figure 1 The structure of a typical plasma display panel is illustrated. [0004] Such as figure 1 As shown, the plasma display panel includes a front panel 100 and a rear panel 110 couple...
