Embodiment Construction

[0047] Hereinafter, embodiments according to the present disclosure will be described with reference to the accompanying drawings. In this specification, when a component (or region, layer, section, etc.) is referred to as being “on”, “connected to” or “joined” to another component, it means that the component can be directly connected / coupled to another component, or the component may be connected / coupled to another component through a third component in between.

[0048] Like reference numerals refer to like parts. Also, in the drawings, thicknesses, ratios, and sizes of components are exaggerated in order to effectively describe technical contents. The term "and / or" includes one or more combinations that can be defined by the associated configuration.

[0049] Terms such as 'first' and 'second' may be used to describe various components, but the components are not limited by the terms. These terms are used only for the purpose of distinguishing one component from other ...

Abstract

A display device provided by the present invention includes a substrate including a display area having pixels disposed and a non-display area surrounding the display area and having a dummy pattern disposed; 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 merge part extending along an X axis direction; and first sub-dummy parts extending from one side of the first dummy merge part to an outer region of the substrate along a Y axis direction perpendicular to the X axis direction.

Description

[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2019-0179720 filed on December 31, 2019, the entire contents of which are hereby incorporated by reference as if fully set forth herein for all purposes. technical field [0003] The present disclosure generally relates to a display device. Background technique [0004] With the development of the information society, various types of display devices have been developed. Recently, various display devices such as liquid crystal displays (LCDs), plasma display panels (PDPs), and organic light emitting displays (OLEDs) have been used. [0005] Organic light emitting elements constituting an organic light emitting display device are self-luminous and do not require a separate light source, so that the thickness and weight of the display device can be reduced. In addition, organic light emitting display devices exhibit high-quality characteristics such...
