Abstract:
Provided is a dispersant including a hydrophobic moiety with a branched alkyl group and an arylene group and a hydrophilic moiety with an alkylene oxide group and a carboxylic acid group. The alkyl group is a substituted or unsubstituted alkyl group of 5-30 carbon atoms, the arylene group is a substituted or unsubstituted arylene group of 6-30 carbon atoms, and the alkylene oxide group is a substituted or unsubstituted alkylene oxide group of 2-10 carbon atoms. The dispersant has good dispersibility, and a low residual carbon content after sintering. Thus, a paste composition including the dispersant can maintain a low viscosity and disperse many inorganic particles. Thus, an inorganic device prepared using the paste composition can have a low residual carbon content and a high packing density.

Abstract:
The present invention relates to a plasma display panel (PDP) that includes a first substrate, an address electrode formed on the first substrate, a dielectric layer formed on the first substrate and covering the address electrode, a barrier rib formed on the dielectric layer, a second substrate, a display electrode formed on the second substrate, a dielectric layer formed on the second substrate and covering the display electrode, and a protection layer formed on the dielectric layer of the second substrate. Discharge cells are defined by barrier ribs, and a phosphor layer is formed in the discharge cells. Barrier ribs contains inorganic adsorbent. When a PDP is operated for a long time, residual carbon or water is generated inside discharge cells, and thereby contaminates a discharge gas contained in the discharge cells. The inorganic adsorbent included in the barrier ribs absorb the residual carbon or water improving efficiency and lifespan of the PDP.

Disclosed is a rear plate of a plasma display panel. In the rear plate, barrier ribs are formed by etching a baked barrier rib layer, so that the completed barrier ribs have no deformation and the electrodes can be exactly located at central portions between the barrier ribs. In a PDP having a front plate to a rear plate attached to each other, the PDP shows improvements in both optical characteristics, such as average brightness, color temperature, and contrast, and electric characteristics, such as voltage margin, power consumption, and efficiency.
