Abstract

A magnesia thin film for plasma display board, plasma display board using the same and manufacture method thereof, the plasma display board comprises: a lower board consisted of a lower substrate wherein a location electrode is formed, a dielectric layer, an interlayer and a phosphor layer; and an upper board consisted of upper substrate wherein a maintenance electrode is formed on the bottom, a scanning electrode, a dielectric layer, a magnesia thin film, the maintenance electrode crosses the location electrode vertically and the upper board integrates with the lower board. The magnesia thin film contains a magnesium-hydrogen conjugate. According to the invention, the magnesia thin film is prevented from the contaminating of carbon dioxide and other impurity, and the discharging voltage is reduced by increasing the quantity of secondary electron radiated by the magnesia thin film, therefore decreasing the power consumption of the plasma display board.

Description

1. Technical field [0001] The present invention relates to a magnesium oxide thin film for a plasma display panel, a plasma display panel using the above magnesium oxide thin film and a manufacturing method thereof, more specifically, a magnesium-hydrogen complex formed on a magnesium oxide thin film of a plasma display panel, The plasma display panel and its manufacturing method can prevent the magnesium oxide film from being polluted by impurities, increase the emission coefficient of secondary electrons, and reduce the discharge voltage. 2. Background technology [0002] The plasma display panel uses the physical phenomenon of gas discharge to display images. As small as a single digit, as large as 2 million pixels, a display device for graphic display with a diagonal of 1m, it is a display element with a wide range of sizes, and it is one of the display devices that are very successful as commercial products. [0003] Plasma display panels have very strong discharge non...
