  • Publication number: 20070120483
    Abstract: The present invention relates to a plasma display apparatus. A bus electrode with high definition is formed and is formed on barrier ribs with a predetermined margin therebetween so that it is not overlapped with a discharge space. Therefore, the bus electrode does not infiltrate into a discharge space due to alignment error on upper/lower substrates. Furthermore, a transparent electrode in which at least one or more projections are formed from the bus electrode to the inside of a discharge space constitutes a scan electrode or a sustain electrode. A width of the transparent electrode is formed to be narrower than that of the bus electrode. Therefore, capacitance by the upper plate electrode can be reduced.
