Abstract:
1. An electroluminescent (EL) image display device which comprises a plurality of stripe-like data electrodes, a light emitting layer, and a plurality of stripe-like scanning electrodes formed on a substrate in sequence, and further comprises an image display portion formed by a plurality of light emitting elements in a matrix form at crossing points between said data electrodes and said scanning electrodes, and a column driving circuit and a row driving circuit for driving said image display portion by selecting and lighting said light emitting elements: wherein, said row driving circuit simultaneously drives more than two of said scanning electrodes and successively lighting horizontal regions in sequence corresponding to the number of simultaneously driven scanning electrodes; and said column driving circuit controls a current flowing in said data electrodes such that the current through said data electrodes is proportional to the number of simultaneously driven scanning electrodes.
