Patent ID: 6930447

Claim:
An organic EL (electroluminescence) device comprising: a plurality of data electrode lines on a substrate; a plurality of scan electrode lines perpendicular to the data electrode lines; and an organic EL layer between the plurality of data electrode lines and the plurality of scan electrode lines, wherein each of the data electrode lines is patterned, and divided into at least two electrode lines in a width direction and a length direction, and wherein each of the data electrode lines includes: a plurality of supplementary electrode lines in a direction perpendicular to a direction of scan electrode lines, a first insulating film having via holes formed on the plurality of supplementary electrode lines, and a plurality of main electrode lines formed on the first insulating film and connected to the plurality of supplementary electrode lines through the via holes, wherein the data electrode lines are formed so that supplementary electrodes are divided into two electrodes in up and down directions and driven at the same time.
