Organic light emitting display device

An organic light emitting display device comprising:

• a substrate on which a plurality of sub-pixels is arranged in a column direction and a row direction;
• a plurality of first electrodes allocated to the plurality of sub-pixels;
• a first bank disposed on the first electrodes and having a plurality of first openings that exposes the plurality of first electrodes;
• and
• a second bank disposed on the first bank and having a plurality of second openings that exposes the plurality of first electrodes and a part of the first bank,
• wherein the plurality of first electrodes include a plurality of (1-1)-th electrodes arranged in a (3n-2)-th column, a plurality of (1-2)-th electrodes arranged in a (3n-1)-th column and a plurality of (1-3)-th electrodes arranged in a 3n-th column, where n is a natural number equal to or greater than 1,
• wherein the first bank is disposed between the plurality of first electrodes neighboring in the column direction and disposed between the (1-3)-th electrodes and the (1-1)-th electrodes neighboring in the row direction,
• wherein the second bank is disposed between the plurality of (1-1)-th electrodes arranged in the (3n-2)-th column and the plurality of (1-2)-th electrodes neighboring the plurality of (1-1)-th electrodes and arranged in the (3n-1)-th column and disposed between the plurality of (1-2)-th electrodes arranged in the (3n-1)-th column and the plurality of (1-3)-th electrodes neighboring the plurality of (1-2)-th electrodes and arranged in the 3n-th column,
• wherein the second bank is not disposed between the plurality of (1-3)-th electrodes arranged in the 3n-th column and the plurality of (1-1)-th electrodes neighboring the plurality of (1-3)-th electrodes in the row direction and arranged in the (3n-2)-th column,
• wherein each (1-1)-th electrode has a first concave portion formed on one side thereof neighboring the (1-2)-th electrode, each (1-2)-th electrode has a first convex portion formed on one side thereof neighboring the (1-1)-th electrode and a second convex portion formed on the other side neighboring the (1-3)-th electrode, and each (1-3)-th electrode has a second concave portion formed on one side thereof neighboring the (1-2)-th electrode, the first concave portion faces the first convex portion and the second concave portion faces the second convex portion,
• wherein the (1-1)-th electrode includes a first part decreasing in width in the row direction in the column direction, and a second part extending from the first part and increasing in width in the row direction in the column direction, and
• wherein the first part and the second part have a planar shape of a right-angled trapezoid.
