Abstract: A light emitting element ink comprises a light emitting element solvent, a light emitting element dispersed in the light emitting element solvent, the light emitting element including a plurality of semiconductor layers, and an insulating film surrounding outer surfaces of the plurality of semiconductor layers, and a thickener dispersed in the light emitting element solvent, wherein the thickener includes a compound represented by Chemical Structural Formula 1 as a polyol-based compound capable of forming a hydrogen bond with the light emitting element solvent or another thickener, and the thickener has a boiling point in a range of about 200° C. to about 450° C.

Abstract: An electrode manufacturing device rolls and transfers a sheet-shaped electrode in which an active material layer is applied to at least any one of a metal foil with a first surface and a second surface which is a back surface of the first surface. At least any one of a rolling roll rolling the electrode and a travel roll rolling and then transferring the electrode comprises a base roll having a predetermined diameter, and having a base surface at an outer circumference thereof; and a step ring being coupled to the outer circumference of the base roll, and having a step surface a diameter of which is greater than a diameter of the base surface. The step ring is detachably coupled to the base roll. A thickness of a step differs from a thickness of the active material layer.

Abstract: The present application relates to a fermented soybean composition and a method for preparing a fermented soybean composition.

Abstract: The present disclosure provides a method for preparing a fermented soybean paste and a fermented soybean paste prepared thereby, the method comprising: a mixing step for mixing a Traditional Korean fermented soybean paste and a modified Korean fermented soybean paste to prepare a mixed fermented soybean paste; a first aging step for primarily aging the mixed fermented soybean paste at room temperature; and a second aging step for secondarily aging mixed fermented soybean paste, which has gone through the primary aging at low temperature.
