    Abstract: The present invention is to provide a liquid crystal display device in which, even when a columnar spacer is misaligned, the columnar spacer can be light-shielded without reduction of an aperture ratio. According to the present invention, there is provided a liquid crystal display device which includes a pair of substrates spaced at a distance from each other by a plurality of columnar spacers, and a liquid crystal layer sandwiched between the pair of substrates, and in which a pixel is formed by picture elements of a plurality of colors, the liquid crystal display device being featured in that one of the pair of substrates includes colored layers of a plurality of colors, and a light shielding layer, in that at least one of the colored layers of the plurality of colors has a region in which a colored layer of the same color is integrally arranged on respective picture elements adjacent to each other, and has a straight portion and an extension portion extending from the straight portion, in that at least one of the plurality of columnar spacers is provided at a position overlapping with the extension portion, and has a substantially rhombus-shaped surface or a substantially circular surface, which is in contact with the substrate, and the contour line of the extension portion has a shape corresponding to the contour line of the columnar spacer provided at the position overlapping with the extension portion.

    Abstract: A color shifting security device has a Fabry-Perot type structure wherein a dielectric layer (702) is disposed between a reflector (701) and an absorbing layer (703). The absorber and reflector layers may be conforming and the dielectric layer therebetween is non-conforming, filling the regions in the micro structured adjacent absorbing or reflecting layer, at least one of which has a microstructure therein or thereon. By having the dielectric layer not conform to the microstructure it is next to, its thickness varies in cross section, which allows for different colors to be seen where the thickness (t1) varies.
