Abstract: A display device includes: a substrate; a polycrystalline silicon film on the substrate; and a first buffer film between the substrate and the polycrystalline silicon film and having one surface contacting the polycrystalline silicon film and another surface opposite to the one surface, wherein the one surface of the first buffer film has a first root mean square (RMS) roughness range, and the first RMS roughness range is 1.5 nm or less.

Abstract: The present invention relates to an emulsified hydrogel composition and to a production method therefor, wherein, by incorporating between 20 and 30 percent by weight of a gelling solution and an emulsion obtained by mixing between 45 and 60 percent by weight of an aqueous component and between 15 and 30 percent by weight of an oil component, it is possible to simultaneously provide the skin with an aqueous fraction and an oil fraction, and it is possible to enhance functionality due to the inclusion of a high content of a dermatologically active component dissolved in the oil component.

Abstract: A semiconductor device includes a substrate having a cell array region and a peripheral circuit region, a lower structure on the substrate in the cell array region, a first insulation layer on the substrate across the cell array region and the peripheral circuit region, the lower structure being covered with the first insulation layer, a capacitor on the first insulation layer in the cell array region, the capacitor including a lower electrode, a dielectric layer patter, and an upper electrode, a second insulation layer on the first insulation layer, the capacitor being covered with the second insulation layer, a first upper wiring structure on the second insulation layer, the first upper wiring structure being electrically connected to the capacitor and including an upper wiring and a mask pattern, and at least one dummy structure in the peripheral circuit region.
