Embodiment Construction

[0065] It will be understood that when an element or layer is referred to as being "on," "connected to," or "coupled to" another element or layer, it can be directly on the other element or layer. An element or layer may be on, connected to, or bonded directly to another element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly connected to” or “directly coupled to” another element or layer, there are no intervening elements or layers present. Like reference numerals refer to like elements throughout. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0066] It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be constrained by these terms. limits....

Abstract

Disclosed are a quantum dot light emitting diode and a display device comprising the quantum dot light emitting diode. In one aspect, a display device includes a plurality of pixels, each pixel including: a first sub-pixel configured to emit blue light; and a second sub-pixel configured to emit a different color based on the strength of an electric field applied to the second sub-pixel of light.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2015-0012310 filed on Jan. 26, 2015, the contents of which are hereby incorporated by reference in their entirety. technical field [0002] The described technology generally relates to a quantum dot light emitting diode and a display device including the quantum dot light emitting diode. Background technique [0003] With the rapid development of society in the information age, the importance of display devices as visual information transmission media is increasing. Displays need to meet design requirements such as low power consumption, thin profile, light weight, and high definition. In recent years, quantum dot light emitting diodes (QD-LEDs) have been actively researched due to their advantageous characteristics such as being thin, having high color purity, having a long operating time, displaying using light-emitting materials, and the like. [0004] Quantum dots are semiconductor nanopartic...
