Abstract: A display device is provided. A display device including a plurality of light-output areas through which incident light is emitted and a light-blocking area which blocks the incident light, the display device includes a substrate, a bank layer which is disposed in the light-blocking area on the substrate and defines a plurality of openings, each of which is disposed in one of the plurality of light-output areas, and a color control pattern disposed in the opening of the bank layer, wherein the bank layer includes a first bank area which has a first thickness and defines the plurality of openings and a second bank area which is disposed between the plurality of openings and has a second thickness smaller than the first thickness.

Abstract: A method of manufacturing an all-solid-state battery electrode, an all-solid-state battery electrode manufactured by the method, and an all-solid-state battery including the electrode are disclosed. In the method, a specific type of binder included in the electrode is prepared in a fiber form by applying pressure to the binder under specific conditions, so that the fiber-form binder thus prepared has an average fineness that satisfies a specific range. Therefore, the all-solid-state battery including the electrode has an advantage of having high capacity even in the case of electrode thickening for high loading.

Abstract: A cathode active material with controlled rheological properties for lithium secondary batteries. In particular, the cathode active material for a lithium secondary battery includes: a core part comprising a lithium metal oxide; and a coating layer covering at least a portion of a surface of the core part and comprising an inorganic compound.

Abstract: A lens unit composed of different materials includes a base and a lens. A part of a camera module of a different material from the lens is used as the base. The lens of optical resin is directly replicated on the base such that the lens is integrally formed on the base. A camera module is provided with the lens unit. The lens/lenses is/are formed on the single base/multiple bases to form the lens unit/units, using a die whose surface contacting the base slopes in relation to its central axis to allow the base to self-align.

Abstract: A wafer-scale array of optical packages and a method for fabricating the same. The wafer-scale array of optical packages includes at least one wafer-scale array of lens structures, including a wafer-scale array of first barrel structures and a wafer-scale array of lenses directly formed on the wafer-scale array of first barrel structures such that the wafer-scale array of lenses is integrally combined with the wafer-scale array of first barrel structures, the wafer-scale array of first barrel structures being made of a material different from a material of the lens of the wafer-scale array of lenses; and at least one wafer-scale array of second barrel structures stacked on and combined with the at least one wafer-scale array of lens structures.
