Abstract
A plasma display apparatus includes a plurality of display element electrodes each constituted of a pair of electrode segments having linear edges opposing each other, with a predetermined distance provided therebetween, the width of each of the electrode segments becoming narrower in the direction away from the associated one of the linear edges. The plasma display apparatus also includes a barrier structure, the inner surfaces of which being disposed along the outer ends of the plurality of display element electrodes and thereby defining a plurality of cells each of which is to be activated by the associated one of the plurality of display element electrodes so as to emit light. In the plasma display apparatus, ultraviolet rays caused by a discharge are efficiently transmitted to phosphor members on the surfaces of cells to emit light with a reduced loss of energy.
