A method is provided for driving a luminescent display which includes a plurality of luminescent units adapted to be selected for light emission, so as to display an image. This method is characterized in that during a predetermined period, a reverse voltage having a direction opposite to that of a voltage to be applied for light emission of a luminescent unit, is applied to each luminescent unit.

Method of driving a luminescent display

A luminescent display panel includes a substrate (,), a plurality of first electrodes (,) formed on the substrate (,), and a plurality of insulating films (,) formed on the substrate (,) to cover edge portions of each first electrode (,) and having the central portion thereof exposed. A luminescent layer (,) is formed on exposed portions of the first electrodes (,) and on the insulating films (,), and a plurality of second electrodes (,) are formed on the luminescent layer (,). Each of the plurality of insulating films (,) has a thickness which becomes gradually smaller toward a center line of each adjacent first electrode (,).

A method for manufacturing an organic EL display panel includes; forming first display electrodes corresponding to emitting portions and bonding pads arranged at a periphery of an image-region as a patterning step; forming electrically insulative ramparts for exposing at least portions of the first display electrodes and protruding from the substrate as a rampart formation step, the each electrically insulative rampart having an overhanging portion projecting in a direction parallel to the substrate preferably at an upper and further having extensions each extending between the adjacent bonding pads to isolate the adjacent bonding pads each other and define a bonding-region between the adjacent extensions on each the bonding pad; depositing organic electroluminescent media onto exposed portions of the first display electrodes respectively, thereby forming organic function layers each including at least one organic electroluminescent medium on the first display electrodes; and forming second display electrodes on the organic function layers and the bonding-regions of the bonding pads so as to electrically connect to the bonding pads.
