Abstract

A display device is provided. The display device includes: a substrate including a display area provided with pixels disposed therein and a non-display area surrounding the display area and provided with dummy patterns disposed therein; a light emitting layer formed on the pixels and the dummy pattern; and a bank surrounding the light emitting layer, wherein the dummy pattern includes: a first dummy portion extending in a horizontal direction; a second dummy portion extending in a vertical direction; and dummy, a third dummy portion provided by extending the first dummy portion and the second dummy portion in a corner region where the first dummy portion and the second dummy portion are connected to each other, the third dummy portion having a pattern protruding in an outward direction of the substrate.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2019-0179740 filed on December 31, 2019, the entire contents of which are hereby incorporated by reference for all purposes as if fully set forth herein. technical field [0003] The present disclosure relates to a display device that prevents the problem of uneven light emission of pixels due to dehumidification. Background technique [0004] With the development of the information society, various types of display devices have been developed. Recently, various display devices have been utilized, such as liquid crystal displays (LCDs), plasma display panels (PDPs), and organic light emitting displays (OLEDs). [0005] Organic light emitting elements constituting an organic light emitting display are of a self-luminous type and do not require a separate light source, thereby reducing the thickness and weight of the display device. In addition, or...
