Abstract: A display device according to one or more embodiments of the disclosure includes a pixel circuit layer including a base layer and circuit elements on the base layer; and a display layer on the pixel circuit layer. The display layer includes a first electrode on the pixel circuit layer; an insulating layer on the first electrode; a second electrode on the insulating layer; a light emitting stacked structure on the second electrode and including a first insulating layer, a second insulating layer, and a light emitting layer between the first insulating layer and the second insulating layer; and a third electrode on the light emitting stacked structure. The light emitting layer includes a two-dimensional material, is separated from the second electrode by the first insulating layer, and is separated from the third electrode by the second insulating layer.

Abstract: Disclosed is a liquid container for containing liquid contents. The liquid container comprises a body with a desired volume for containing liquid contents; a narrow neck formed at an upper side of the body; an opening formed at an inside of the neck so as to be communicated with an inside of the body; and an air path extended from the upper side of the body to an upper side of the neck so as to be opened at upper and lower end thereof so that an entrance of the opening is communicated with an inside of the body, wherein a lower opening of the air path has an inclined section which is inclined upward at a desired angle relative to a reference surface of the liquid contents in the body. Additionally, the air path has a length so that the lower opening thereof is not contacted with the reference surface of the contents.
