Abstract

A display apparatus including a light-emitting device is provided. The light-emitting device is disposed on a display area of a device substrate. An over-coat layer between the device substrate and the light-emitting device extends onto a bezel area. A moisture-blocking hole penetrating the over-coat layer is disposed on the bezel area. At least a portion of the moisture-blocking hole is filled by an encapsulating element disposed on the light-emitting device. A front adhesive layer covering the encapsulating element may attach an encapsulation substrate to the device substrate in which the light-emitting device and the encapsulating element are formed. A variable adhesive layer is disposed between the encapsulating element and the front adhesive layer and/or the over-coat layer and the front adhesive layer of the bezel area. Thus, in the display apparatus, the penetration of external moisture may be blocked, and the process efficiency and the productivity may be improved.
