Abstract
Disclosed are an organic light emitting display device with improved yield and processing efficiency, which includes an interlayer capable of being separated into a hydrophilic region and a hydrophobic region on top of a hole injection layer in an organic light emitting device and a plurality of layers including a light emitting layer and which is fabricated without using a shadow mask, as well as a method for manufacturing the same. The manufacturing method includes preparing a substrate having a plurality of pixel regions defined in a matrix form, arranging an anode in each of the pixel regions, forming a hole injection layer on the anode by the solution process, forming an interlayer with hydrophobic properties on the hole injection layer by a solution process, selectively UV irradiating the interlayer to define a hydrophilic region on the interlayer, forming a light emitting layer on the interlayer by the solution process, and arranging a cathode on the substrate having the light emitting layer.
