Abstract: A pixel includes first, second, and third sub-pixels each including an emission area and a non-emission area. Each of the first, second, and third sub-includes a pixel circuit layer; a first electrode on the pixel circuit layer; a pixel defining layer on the first electrode and including an opening to expose an area of the first electrode; an emission layer on the pixel defining layer; a second electrode on the emission layer; a thin film encapsulation layer over the second electrode; a color filter on the thin film encapsulation layer; and an overcoat layer over the color filter. The overcoat layer has a refractive index greater than a refractive index of the color filter. A color filter of the second sub-pixel overlaps a color filter of each of the first and third sub-pixels in the non-emission area.

Abstract: Disclosed are an oxidizing electrode, a water electrolysis device including the same and a method for manufacturing the same. According to exemplary embodiments of the present disclosure, there is provided an oxidizing electrode with improved performance at low loadings of noble metals, especially, ruthenium (Ru) and iridium oxide, in which a ruthenium (Ru) layer and an iridium oxide layer formed on a substrate by electrodeposition in a sequential order are supported by electrochemical reaction rather than physical bonding.

Abstract: An electrode drying apparatus and a method of manufacturing an electrode using the same is provided. In the electrode drying apparatus, by inducing static electricity onto a back side of an electrode current collector of which a front surface is coated with an electrode slurry so that the electrode slurry has an electric charge opposite to an electric charge of an ionic binder contained in the electrode slurry as a binder, even when solvent volatilization occurs during a drying process of the electrode slurry, it is possible to prevent binders from being moved to a surface of the electrode slurry, and thus it is possible to improve an adhesive force between an electrode mixture layer formed by drying the electrode slurry and the electrode current collector.
