Embodiment Construction

[0028] Embodiments will be described below with reference to the accompanying drawings. In this specification, if a constituent element (or a region, layer or section, etc.) is described as being "existing on", "connected to" or "combined with" different constituent elements, Then it means that the constituent element may be directly connected / combined with different constituent elements, or a third constituent element may be arranged therebetween.

[0029] The same reference numerals refer to the same constituent elements. Further, in order to effectively describe the technical contents, the thicknesses, proportions and dimensions of the constituent elements are expressed in an exaggerated manner in the drawings. The phrase "and / or" is used to include one or more combinations that may be defined by the associated elements.

[0030] The terms first and second, etc. may be used to describe various constituent elements, but should not impose any limitations on their meanings. ...

Abstract

A display device includes: a substrate including a light emitting region forming an open region and a non-light emitting region adjacent to the light emitting region; a circuit element layer formed in the non-emission region; and a bank layer covering a top of the circuit element layer, in which the bank layer is not formed in the light emitting region.

Description

technical field [0001] The present invention relates to a display device and a method of manufacturing the same. Background technique [0002] An organic light-emitting element (hereinafter referred to as a light-emitting element for short) is a self-luminous element that does not require a separate light source, thereby reducing the thickness and weight of the display device. In addition, the characteristics of the organic light emitting display device include low power consumption, high brightness, and high responsiveness, among others. [0003] Generally, the light-emitting element has a structure in which an anode, a bank surrounding an edge region of the anode, a light-emitting layer formed on top of the anode inside the bank, and a cathode covering the light-emitting layer and the bank are stacked on top of each other. [0004] When the banks and the cathodes are arranged in an overlapping manner, a light escape phenomenon in which light is reflected internally and es...
