Stage: PROBLEM TO BE SOLVED: To provide an organic light emitting display device having high aperture ratio and emitting efficiency and improved lifespan.SOLUTION: A dual side organic light emitting display device comprises: a first driving element and a second driving element that are positioned over a transparency substrate in a first region; a first organic light emitting diode that includes a first electrode positioned over the first and second driving elements in a second region and connected to the first driving element, a second electrode positioned over the first electrode, and a first organic light emitting layer positioned between the first and second electrodes; and a second organic light emitting diode that is positioned in the first and second regions and on the first organic light emitting diode, and includes a third electrode positioned over the second electrode, and connected to the second driving element, and a second organic light emitting layer positioned between the second and third electrodes. A light from the first organic light emitting diode is emitted toward a first direction via the first electrode, and a light from the second organic light emitting diode is emitted toward a second direction, which is opposite to the first direction, via the third electrode.SELECTED DRAWING: Figure 4 (Grant)
