An organic light-emitting device, comprising: a first electrode; a second electrode; and an organic layer located between the first electrode and the second electrode, wherein the organic layer comprises an emission layer, wherein the emission layer comprises a host, a sensitizer, and an emitter, wherein the host, the sensitizer, and the emitter are different from each other, and wherein the sensitizer is represented by Formula 1:M(L)(L)  Formula 1wherein, in Formula 1, Mis Au, Ag, or Cu, Lis a ligand represented by Formula 2-1 or Formula 2-2, and Lis a ligand represented by one of Formulae 3-1, 3-2, or 3-3: wherein A, A, A, X, Rto R, Rto R, b23, and b33 are as defined herein, and * indicates a binding site to Min Formula 1.

Organic light-emitting device

A refrigerator includes an outer case forming the exterior of a main body, an inner case disposed inside the outer case to form a storage compartment, an upper duct including an upper outlet to discharge cold air downward toward the storage compartment, and disposed in the inner case to form an upper flow path to supply cold air to the upper outlet, a rear duct including a rear flow path configured to guide the cold air to the upper flow path, and a rear outlet configured to discharge cold air from the rear flow path into the storage compartment, a light emitting diode (LED) module coupled to the upper duct to emit light toward the storage compartment and including a plurality of LEDs, and a reflective cover disposed on a rear side of the storage compartment to be coupled to the rear duct and reflecting light from the LED module.

Refrigerator

A refrigerator including a storage compartment and a cold air duct to guide cold air to the storage compartment, the cold air duct including a front plate facing the storage compartment, the front plate including a front body with a first coupling portion, a rear plate detachably coupled to the front plate, the rear plate including a rear body with a second coupling portion, and a slit in the rear body so that the second coupling portion is elastically deformable, and a heat insulating member between the front plate and the rear plate. The first coupling portion is coupled to the second coupling portion. The first coupling portion and the second coupling portion are decouplable by an external force pressing on the first coupling portion.

Plate assembly and home appliance

A refrigerator includes a body including an inner case, a first storage compartment, a second storage compartment, a third storage compartment, a first partition between the second storage and the third storage compartments, a second partition between the first and the second storage compartments, a cold air supplier in the third storage compartment to generate cold air, a first communication hole, a second communication hole to face the first communication hole, a first guide duct formed in the first partition to guide the cold air from the first communication hole to the second communication hole, and a second guide duct formed in the second partition to guide the cold air which has flown to the first guide duct, to the second storage compartment, the second guide duct connected to the first guide duct through the second communication hole.

Provided is a refrigerator that includes a storage compartment, a shelf disposed inside the storage compartment, an angle provided to fix a position of the shelf, and a duct mounted on one surface of the storage compartment and to which the angle is coupled. The angle includes a bent part formed to be bent inward from one end of the angle, and the duct includes a fixing protrusion disposed to protrude from the duct toward the storage compartment so as to fix the angle by pressing an inner surface of the bent part.

A refrigerator includes an outer case, an inner case coupled to the outer case and equipped with a storeroom, a heat exchanger disposed adjacent to the storeroom to supply cold air, and a front cover defining one side of the storeroom. The front cover includes at least one end having a recessed portion that forms a cold air supply port to supply cold air supplied from the heat exchanger into the storeroom.

Disclosed is a refrigerator including a temperature controlled room with improved utilization of space because no component for cooling or heating is positioned inside a temperature controlled room. The refrigerator includes a cabinet; a storage room provided inside the cabinet; a temperature controlled room positioned inside the storage room and being at inside temperature which is independent from inside temperature of the storage room; a cool air flow path guiding cool air generated inside the cabinet to inside of the storage room; a first fan positioned on the cool air flow path to supply the cool air to the storage room; a cool air supplier forming at least one portion of the cool air flow path and including a second fan to supply the cool air to the temperature controlled room; and a heating portion configured to heat air to supply hot air to inside of the temperature controlled room.

An organic light-emitting device including a first electrode, a second electrode facing the first electrode, and an organic layer disposed between the first electrode and the second electrode, wherein the organic layer includes an emission layer, wherein the emission layer includes a host and a dopant, and wherein the organic light-emitting device satisfies predetermined conditions described in the specification.

Disclosed herein are a coumarin-based derivative compound, a preparation method thereof, and a fluorescent composition containing the same.
