Abstract:
Disclosed is an organic light emitting display apparatus. An outer portion of an adhesive layer is set higher in degree of cure than a center portion of the adhesive layer, and thus, a driving defect is prevented from occurring because the adhesive layer stretches in a manufacturing process, and various defects are prevented from being caused by a jig, thereby enhancing reliability and productivity of the organic light emitting display apparatus.
