Abstract

A display device is provided. The display device may comprise: a first electrode; a second electrode arranged to be spaced apart from and face the first electrode; a first insulation layer arranged to partially cover the first electrode and the second electrode; a second insulation layer arranged on at least a part of the first insulation layer; and a light emitting element which is arranged between the first electrode and the second electrode on the second insulation layer, and has a lower surface, at least a part of which chemically combines with the second insulation layer.

Description

technical field [0001] The present disclosure relates to a display device, and more particularly, to a display device in which an organic pattern formed on a surface of an electrode is chemically bonded to a light emitting element. Background technique [0002] With the development of multimedia technology, display devices become more and more important. Accordingly, various types of display devices, such as organic light emitting display (OLED) devices and liquid crystal display (LCD) devices, are currently used. [0003] The display device is used to display images, and includes a display panel such as an organic light emitting display panel or a liquid crystal display panel. Among them, the light emitting display panel may include light emitting elements. For example, light emitting diodes (LEDs) may include organic light emitting diodes (OLEDs) using organic materials as fluorescent materials and inorganic light emitting diodes using inorganic materials as fluorescent ...
