Abstract: A display device includes a substrate having a light emitting area and a non-light emitting area; a first anode electrode on the light emitting area of the substrate; a pixel defining layer on the non-light emitting area of the substrate and defining a first opening; an organic separator layer on the pixel defining layer and defining a second opening; a first light emitting layer on the first anode electrode; a common electron layer on the first light emitting layer and the organic separator layer; and a common electrode on the common electron layer, wherein the organic separator layer does not overlap the light emitting area, and overlaps the non-light emitting area to be in contact with the pixel defining layer, the first light emitting layer, and the common electron layer.

Abstract: A semiconductor memory device, and a method of manufacturing the semiconductor memory device, includes a first source layer, a second source layer on the first source layer, a stack on the second source layer, a channel structure passing through the stack and the second source layer, and a common source line passing through the stack and the second source layer. The second source layer includes an air gap and a conductive layer surrounding the air gap.

Abstract: A scroll compressor is provided. A value obtained by multiplying a wrap height (H) by a driving speed (V) may be controlled to be within a range of approximately 500˜1000 mmHz at a low speed driving (less than approximately 35 Hz). The wrap height of the scroll compressor, and the driving speed may be set to be optimum, thereby preventing the scroll compressor from being operated at a speed excessively lower or higher than a predetermined driving speed. This may allow the scroll compressor to be operated at an optimum low speed corresponding to the wrap height, and thus, the compressor and a refrigerating cycle apparatus having the same may have enhanced performances.
