Organic Light Emitting Display Device

An organic light emitting display device comprising:

• a substrate having a first sub-pixel, a second sub-pixel, a third sub-pixel, and a fourth sub-pixel sequentially arranged in a clockwise direction in a form of a 2×2 matrix;
• a first color filter disposed in the first sub-pixel;
• a second color filter disposed in the second sub-pixel;
• a third color filter disposed in the third sub-pixel;
• and
• a planarization layer covering the first, second, and third color filters,
• wherein the planarization layer has a concave portion of a lens shape in the fourth sub-pixel,
• wherein the concave portion has a width greater than a width of the fourth sub-pixel,
• wherein each of a side face of the first color filter adjacent to the fourth sub-pixel and a side face of the third color filter adjacent to the fourth sub-pixel has a concave area.
