    Abstract: An organic light emitting display device and method of fabricating thereof is disclosed. The organic light emitting display device comprises a first substrate; a plurality of first bank layers arranged along a first direction and a second direction on the first substrate to define a plurality of pixels, where the first direction and the second direction are orthogonal; a plurality of second bank layers disposed along the first direction on the first bank layers to divide pixels columns of different colors; and an organic light emitting diode in each pixel, the organic light emitting diode including an organic light emitting layer having different thicknesses on different colored pixels, wherein the side surfaces of the second bank layer adjacent to the pixel columns of different colors are inclined, the inclined angle thereof is dependent upon a thickness of the organic light emitting layer in the pixel.
