Abstract

A display apparatus in which an encapsulation function is enhanced, and thus, the penetration of external water and oxygen are minimized. The display apparatus includes a substrate, a light emitting device provided on the substrate, a first adhesive layer provided on the light emitting device to cover the light emitting device, and a first encapsulation substrate provided on the first adhesive layer. A side surface of the first adhesive layer is covered by the first encapsulation substrate.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2019-0172132 filed on December 20, 2019, which is hereby incorporated by reference as if fully set forth herein. technical field [0003] The present disclosure relates to a display device. Background technique [0004] With the development towards the information society, various requirements for display devices for displaying images are increasing. Therefore, various display devices such as liquid crystal display (LCD) devices, plasma display panels (PDP) and organic light emitting display devices are being used recently. [0005] The organic light-emitting display device in the display device is a self-luminous display device and does not require a separate backlight. Therefore, the organic light emitting display device can be realized to be light and thin and have low power consumption, compared with an LCD device. Also, the organic light em...
