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 circul…
