In this case, the cost for the equipment for forming the element insulating layer may be additionally consumed
[0005] Therefore, in order to omit the formation of an additional element insulating layer, it is conceivable to form the first contact electrode and the second contact electrode on the same layer. In this case, when forming the first contact electrode There is a limitation on the resolution of the photolithography machine or the overlay (Overlay) capability of the photolithography machine of the second contact electrode

Abstract
The invention relates to a display device and a method of manufacturing the same. The display device includes: a substrate portion; first banks disposed on the substrate portion so as to be spaced apart from each other; a first electrode and a second electrode disposed on the first bank and disposed to cover the first bank and spaced apart from each other; a light emitting element disposed between the first electrode and the second electrode; a first contact electrode connected to the first electrode and in contact with one end of the light emitting element; and a second contact electrode connected to the second electrode and in contact with the other end of the light emitting element, in which the first contact electrode includes a first substance, the second contact electrode includes a second substance, and the physical properties of the first substance and the second substance are different.
Description
technical field [0001] The invention relates to a display device and a manufacturing method of the display device. Background technique [0002] With the development of an information society, demands on display devices for displaying images are increasing in various forms. For example, display devices are applied to various electronic devices such as smart phones, digital cameras, notebook computers, navigators, and smart TVs. The display device may be a flat panel display device such as a Liquid Crystal Display Device, a Field Emission Display Device, or an Organic Light Emitting Display Device. Among these flat panel display devices, the light-emitting display device includes light-emitting elements capable of making pixels of the display panel emit light individually, so that an image can be displayed without a backlight unit that supplies light to the display panel. [0003] In addition, the display panel has a multilayer structure including a bank layer, a plurality ...
