Abstract: A display device includes a display panel including an antireflection layer on a light emitting element layer which includes a first pixel defining layer in which an opening defining a light emitting area of a first pixel is defined, and a second pixel defining layer in which an opening defining a light emitting area of a second pixel is defined. The antireflection layer includes first and second light blocking layers respectively overlapping the first and second pixel defining layers, and includes a first gap defined by a length of a predetermined direction from an edge of the opening to an edge of an opening of the first light blocking layer, and a second gap defined by a length from an edge of the opening to an edge of an opening of the second light blocking layer in the predetermined direction. The first gap is less than the second gap.

Abstract: An organic light-emitting display device includes: a display panel having a first display area and a second display area, the first and second display areas having different light transmittances from each other in a unit area, wherein the display panel includes a plurality of organic light-emitting diodes disposed in the first display area and the second display area, wherein a first organic light-emitting diode disposed in the first display area and a second organic light-emitting diode disposed in the second display area each include at least one light emitter, and the number of the light emitter included in the second organic light-emitting diode is greater than the number of the light emitter included in the first organic light-emitting diode.

Abstract: A method for obtaining a collagen peptide from a starfish, an elastic liposome containing a starfish-derived collagen peptide, and a cosmetic composition containing the same are disclosed. Methods of using the collagen peptide or the elastic liposome are disclosed. The collagen peptide obtained from a starfish has excellent skin absorption rate and having anti-oxidation and wrinkle-improving activity. Thus, the collagen peptide may replace existing animal collagen to provide collagen with high extraction efficiency.

Abstract: Provided is an ecofriendly snow removal composition using a porous structure of calcium carbonate obtained by removing proteins from starfish to adsorb chlorine ions. The ecofriendly snow removal composition uses a starfish-derived porous structure to adsorb the chlorine ions contained in the snow removal composition, so it can minimize the effects of the chlorine ions on the corrosion on roads, facilities, vehicle bodies, etc. to reduce the environmental contamination in roadside trees, rivers, etc. and also display an equivalent deicing performance to the conventional snow removal composition using calcium carbonate. Further, the novel snow removal composition using starfish are ecofriendly and beneficial in the aspect of cost, as it utilizes starfish that are adversely affecting the ecosystem and difficult to dispose of.
