Plasma display panel

#This application makes reference to, incorporates the same herein, and claims all benefits accruing under 35 U.S.C. §119 from an application for PLASMA DISPLAY PANEL earlier filed in the Korean Intellectual Property Office on 29 Mar. 2006 and there duly assigned Serial No. 10-2006-0028281.

#1. Field of the Invention

#The present invention relates to a plasma display panel and, more particularly, to a plasma display panel that can reduce an appearance of a stain around an exhaust aperture and an exhaust tube.

#A more complete appreciation of the invention and many of the attendant advantages thereof, will be readily apparent as the same becomes better understood by reference to the following detailed description when considered in conjunction with the accompanying drawings in which like reference symbols indicate the same or similar components, wherein:

#FIG. 1 is a rear perspective view of a plasma display panel according to an exemplary embodiment of the present invention;

#FIG. 2 is a partially exploded perspective view of a plasma display panel according to an exemplary embodiment of the present invention;

#Turning now to the figures, FIG. 1 is a rear perspective view of a plasma display panel according to an exemplary embodiment of the present invention where the rear and front substrates 10 and 20 are shown as being directly sealed together and FIG. 2 is a partially exploded perspective view of a plasma display panel according to an exemplary embodiment of the present invention. Referring to FIGS. 1 and 2, a plasma display panel of this exemplary embodiment includes first and second substrates (hereinafter, “rear and front substrates”) 10 and 20 facing each other at a predetermined interval and sealed together via a frit sealant 18 with barrier ribs 16 provided between the rear and front substrates 10 and 20. The barrier ribs 16 are formed to a predetermined height between the rear and front substrates 10 and 20 to define a plurality of discharge cells 17. A height (in the z direction) of the discharge cell 17 is much less than a width of each of the rear and front substrates 10 and 20. The discharge cells 17 are filled with a discharge gas (e.g., a mixture gas including neon (Ne) and xenon (Xe)) to produce vacuum ultraviolet rays via a gas discharge. The discharge cells 17 have phosphor layers 19 for emitting visible light by absorbing the vacuum ultraviolet rays.

#In order to display an image via gas discharge, the plasma display panel includes address electrodes 11, first electrodes (hereinafter, “sustain electrodes”) 31, and second electrodes (hereinafter, “scan electrodes”) 32, all of which are arranged between the rear and front substrates 10 and 20 in response to the discharge cells 17. The address electrodes 11 are covered with a dielectric layer 13 deposited on an inner surface of the rear substrate 10. The dielectric layer 13 prevents the address electrodes 11 from being damaged by preventing positive ions or electrons from directly colliding with the address electrodes 11, and generates and accumulates wall charges therein. Since the address electrodes 11 are arranged on the rear substrate 10 so as not to interfere with the irradiation of the visible light toward the front substrate 20, the address electrodes 11 can be formed of a nontransparent material. For example, the address electrodes 11 can be formed of metal that has a high level of electric conductivity.

#The barrier ribs 16 are provided on the first dielectric layer 13 to define the discharge cells 17. As an example, the barrier ribs 16 can be spaced apart from each other along a x direction and extend along the y direction to form the discharge cells in a striped pattern. When barrier ribs extending in the x direction are can also be formed between the barrier ribs 16 and extend along the y direction, the discharge cells can be formed in a matrix pattern. This matrix pattern structure is not illustrated in the drawings.
