Abstract
An organic light emitting display device is disclosed. The organic light emitting display device includes a substrate, a first electrode, a pixel defining layer, a first hydrophobic pattern, at least one charge transport layer, a second hydrophobic pattern, an organic light emitting layer and a second electrode. The substrate has a pixel region and a non pixel region surrounding the pixel region. The first electrode, the at least one charge transport layer and the organic light emitting layer are disposed on the substrate in the pixel region, while the pixel defining layer, the first hydrophobic pattern and the second hydrophobic pattern are disposed on the substrate in the non pixel region. The charge transport layer of one pixel is separated from a charge transport layer of another pixel by the first and second hydrophobic patterns to prevent crosstalk phenomenon.
