Abstract
An organic light emitting display device may include a first substrate, a first electrode disposed on the first substrate, a pixel defining layer disposed on the first electrode and the first substrate, an organic light emitting structure disposed on the first electrode, a second electrode disposed on the organic light emitting structure and the pixel defining layer, a second substrate disposed on the second electrode, etc. The pixel defining layer may include a fine uneven structure positioned in the display and the non-display regions. The organic light emitting structure may be substantially uniformly formed on the first electrode through the pixel defining layer having the fine uneven structure, so that an organic light emitting display device may exhibit increased lifetime and may show improved image quality.
