Embodiment Construction

[0031] figure 1 is a partially exploded perspective view showing a plasma display panel according to an embodiment of the present invention, figure 2 is along figure 1 A partial cross-sectional view taken along line II-II.

[0032] refer to figure 1 and 2 , the rear substrate 10 and the front substrate 20 are arranged to face each other with a predetermined gap therebetween. In the space between the substrates 10 and 20 , a plurality of discharge cells 18R, 18G, and 18B are formed by the configuration of the barrier ribs 16 .

[0033] In each discharge cell 18 , phosphor layers 19 are formed on wall surfaces 161 and bottom surfaces 141 of the ribs. Each discharge cell 18 is filled with a discharge gas (eg, containing Xe and Ne) that generates a plasma state and ultraviolet light that excites phosphors by applying a specific voltage in the cell. After excitation, the phosphor molecules emit visible light when returning to their normal state.

Abstract

A plasma display panel having improved exhaust efficiency is disclosed. A plasma display panel according to a first embodiment of the invention includes first and second substrates opposing each other; barrier ribs that are located in a space between the first substrate and the second substrate for dividing a plurality of discharge cells in sealed spaces; display electrodes located along the discharge cells; and address electrodes formed in a direction intersecting the display electrodes. The barrier ribs include first barrier ribs having a first height and second barrier ribs having a second height so that the difference in height between the two ribs is provided.

Description

technical field [0001] The present invention relates to a plasma display panel device, and more particularly, to a plasma display panel with improved exhaust efficiency. Background technique [0002] In general, a plasma display panel (hereinafter referred to as PDP) is a display device in which ultraviolet rays emitted from plasma generated by gas discharge excite phosphors to emit visible light, thereby realizing a predetermined image. [0003] A PDP device utilizing a three-electrode surface discharge type structure has been widely known. This type of PDP device includes a first substrate, display electrodes formed on one side of the first substrate, a second substrate spaced apart from the first substrate, and a substrate formed on one side of the second substrate in a direction substantially perpendicular to the display electrodes. The address electrode (address electrode). The display electrodes include scan electrodes and sustain electrodes. A discharge gas is seal...
