The present disclosure relates to a display device including an optical device, more specifically, it relates to a display device in which the optical device is positioned under the display panel so that the optical device is not exposed in the front direction. Even if the optical device is located under the display panel, the display device can normally perform the function of the optical device related to the front direction of the display panel and have a structure for this.

The present invention relates to a novel phenanthroline-based compound and an organic light-emitting device having high efficiency characteristics comprising same. More particularly, the present invention relates to a phenanthroline-based compound exhibiting high efficiency by including a phenanthroline-based compound having a specific structure as a material for a charge generation layer in an organic light-emitting device, and to an organic light-emitting device comprising same, wherein [Chemical Formula A] is the same as described in the detailed description of the invention.

Disclosed herein are light emitting device that emit highly circularly polarized light. These devices may be used to form a dot-matrix display or an electronic information display comprised of a series of photopolymerizable, chiral liquid crystalline layers that can be solvent cast on a substrate. The mixture of chiral materials in each successive layer may be blended in such a way that each layer has the same chiral pitch and may also be blended so that the ordinary and extraordinary refractive indices in each layer match the other layers such that the complete assembly of layers will optically function as a single relatively thick layer or chiral liquid crystal. The chiral nematic material in each layer can spontaneously adopt a helical structure with a helical pitch. Further disclosed are pixel structures that not only emit light with brightness and chromaticity information, but also depth of focus information as well.

An organic light-emitting device includes a first electrode, a second electrode facing the first electrode, an organic layer between the first electrode and the second electrode and including an emission layer, and at least one of a first layer and a second layer, wherein the first layer is positioned in a path where light generated in the emission layer is transmitted to the outside through the first electrode and the second layer is positioned in a path where the light generated in the emission layer is transmitted to the outside through the second electrode. The first layer and the second layer each include a compound having a certain formula.

A light-emitting diode, a method for fabricating the same, and a display device are disclosed. The light-emitting diode includes a first and second electrode; a first carrier transporting layer, a light emitting layer, and a second carrier transporting layer which are arranged between the first and second electrode in this order The light-emitting diode further includes a second carrier transporting layer which is arranged between the light emitting layer and the second electrode. The second carrier blocking layer blocks a portion of the second carrier from being transported to the light emitting layer. This decreases the injecting efficiency of the second carrier, improves an injecting balance between the second carrier and the first carrier with a low injecting efficiency, avoids energy consumption in the form of heat, and increases the light output efficiency and lifetime of the light-emitting diode.
