Display device having a plurality of discharge cells in each unit light-emitting area

摘要

A display device capable of preventing erroneous discharge and improving the quality of display. The display panel has a unit light-emitting area formed at the intersection of row and column electrodes which is structured by a first discharge cell and a second discharge cell having a light absorbing layer at a side close to a front substrate and a secondary-electron emitting material layer at a side close to a back substrate. While applying a scanning pulse having a polarity to place the column electrode in low potential to one row electrode of a row electrode pair, a pixel data pulse having a voltage commensurate with pixel data is applied to the column electrode, thereby selectively causing address discharge within the second discharge cell. With this structure, because the column electrode within the second discharge cell acts as a cathode relative to the row electrode, secondary electrons are to be emitted favorably from the secondary-electron emitting material layer formed within the second discharge cell, thus positively causing address discharge.
