Abstract: A plasma sensor module may include an upper substrate, a lower substrate, at least one probe and a printed circuit board (PCB). The upper substrate may be configured to be exposed to plasma. The lower substrate may contact a lower surface of the upper substrate. The lower substrate may have a thickness that is thicker than a thickness of the upper substrate. The probe may be in the lower substrate. The PCB may be in the lower substrate. The PCB may be configured to apply an alternating current to the probe to detect a density of the plasma. Thus, the structural strength of the plasma sensor module may have improved structural strength.

Abstract: A display device can include a substrate having a display area including a plurality of light emitting diodes, a first non-display area, and a bending area disposed between the first non-display area and the display area; a first inorganic encapsulation layer on the plurality of light emitting diodes; and a data driver in the first non-display area, in which the substrate is configured to be bent at the bending area for locating a portion of the first non-display area that includes the data driver under or behind a portion of the display area, and the first inorganic encapsulation layer includes a first region configured to overlap with the data driver and a second region that does not overlap with the data driver, the first region of the first inorganic encapsulation layer having a higher refractive index than the second region of the first inorganic encapsulation layer.

Abstract: Provided is an organic light emitting display device including at least two organic light emitting elements disposed adjacent to each other, respectively including an anode, an organic light emitting unit, and a cathode, and sharing at least one common layer in the organic light emitting unit. The at least one common layer includes a characteristic degradation area that reduces or minimizes an amount of leakage current generated between the at least two organic light emitting elements.
