Abstract: An organic light emitting display device and a method of fabricating thereof are discussed. The organic light emitting display device according to an example includes a plurality of first bank layers arranged along a first direction and a second direction on a substrate to define a plurality of pixels; a plurality of second bank layers disposed along the first direction on the first bank layers to divide the columns of pixels having different colors; an organic light emitting layer in each pixel; at least one first pocket pixel unit at both sides of the pixel having the smallest area; and a first dummy organic light emitting layer in the first pocket pixel unit.

Abstract: An electroluminescent display device comprises a substrate; a plurality of sub-pixels arranged on the substrate, including sub-pixels with different colors arranged along a first direction and sub-pixels with a same color arranged along a second direction; a light-emitting diode disposed at each sub-pixel and including a first electrode, a light-emitting layer and a second electrode; a bank having an opening corresponding to a sub-pixel row along the second direction and disposed between two adjacent sub-pixels along the first direction; and a control pattern between two adjacent sub-pixels along the second direction, wherein the control pattern includes a first control pattern corresponding to a center portion of the sub-pixel row and a second control pattern spaced apart from the first control pattern along the second direction, and where a first end of each of the first and second control patterns is spaced apart from the bank and has an first surface parallel to or inclined with respect to the second direction, and a slope of the first surface of the second control pattern is larger than a slope of the first surface of the first control pattern.
