Abstract
A PALC display apparatus comprising groups of cathode electrodes K and groups of anode electrodes A, each group consisting of, for example, three electrodes. The cathode electrodes of each group are connected by a multi-connection line KK, and the anode electrodes of each group are connected by a multi-connection line AA. Thus, a plurality of multi-connection lines KK and a plurality of multi-connection lines AA are provided. Of these multi-connection lines, two lines KK and two lines AA are selected. A voltage is applied to the cathode electrodes K connected by the selected multi-connection lines KK, and a voltage of the opposite polarity is applied to the anode electrodes A connected by the selected multi-connection lines AA. Discharge is thereby effected between the selected electrodes only. Therefore, the PALC display apparatus can be manufactured at low cost and can display high-quality images.
