Abstract
An organic light emitting display device comprises a first substrate, an insulation layer having an inclined structure, a first electrode, a pixel defining layer defining a luminescent region and a non-luminescent region, an organic light emitting structure, a second electrode and a second substrate. Lateral portions of the first electrode, the second electrode and/or the pixel defining layer may have an inclination angle for preventing a total reflection of light generated from the organic light emitting structure, so that the organic light emitting display device may ensure a light efficiency substantially larger than that of the conventional organic light emitting display device by about at least 30 percent.
