ABSTRACT:
An organic electroluminescent (EL) display device is provided which can reduce a level of power consumption. The organic EL display device includes a plurality of anode columns formed on a substrate, each anode column having first and second anodes disposed adjacent to each other, with emitting areas of the first and second anodes being arranged alternately in a line; a plurality of walls intersecting the anode columns. A plurality of cathodes are formed between walls which intersect the anode columns to form two sub pixels. A plurality of secondary walls are formed between two adjacent walls, between the light emitting areas of the first and second anodes of each anode column. Each secondary wall may include a plurality of unit walls corresponding to one pixel with first, second and third sub pixels which emit different colored lights. Alternatively, each subsidiary wall may include a plurality of unit walls, with each unit wall corresponding to one of the first, second or third sub pixels.
