Abstract
An organic light emitting display device includes a substrate which is divided into an active area and a non-active area. An adhesive film and an encapsulation substrate are disposed above the substrate, and a dam is disposed in the non-active area between the substrate and the encapsulation substrate. The dam includes a polymer light emitting material that is transparent when irradiated with visible light but emits light when irradiated with ultraviolet light. Therefore, external appearance of the dam can be inspected and performance of the dam can be evaluated using ultraviolet rays.
