20100308708FILM CONTAINING CONJUGATED POLYMER CHAINS AND METHOD OF PRODUCING THE SAME - A method of producing a film containing an oxide having a plurality of tubular structures and a plurality of conjugated polymer chains includes preparing a solution by dissolving a precursor substance having a first site containing a precursor of the oxide and a second site containing a precursor of a component constituting the conjugated polymer chains; forming a film containing the oxide having the tubular structures on a substrate, the surface of which exhibits anisotropy, by applying the solution onto the substrate so that the tubular structures and the conjugated polymer chains are oriented; and forming the conjugated polymer chains in pores of the tubular structures by polymerizing the second site in the film formed on the substrate, wherein an inorganic component of the first site is connected to carbon of the second site through a covalent bond.12-09-2010
20110234084ELECTROLUMINESCENT DISPLAYS - An electroluminescent display comprising a mask defining the information to be displayed and an electroluminescent (EL) backlight. The mask compress a layer (09-29-2011
20120019123LIGHT EMITTING DEVICE - According to one embodiment, a light emitting device includes a light emitting element, a molded body, a first sealing layer, and a converging lens. The light emitting element has a first surface and a second surface opposite to the first surface, with an optical axis of emission light being perpendicular to the second surface. The molded body includes a recess. The first surface side of the light emitting element is disposed in the recess. The first sealing layer covers the light emitting element in the recess and includes a first transparent resin and phosphor particles. The converging lens is provided on an upper surface of the first sealing layer and has a refractive index increasing with increase of distance from the optical axis. The refractive index at a position in contact with an outer edge of the upper surface of the first sealing layer is higher than a refractive index of the first transparent resin.01-26-2012
