  • Publication number: 20110059263
    Abstract: A retardation layer that includes regions causing different retardations can be manufactured easily. A retardation substrate includes a substrate and a solidified liquid crystal layer supported by the substrate. The solidified liquid crystal layer includes first to third regions. The first to third regions re arranged on the substrate and different in degree of orientation of mesogens.

  • Patent number: 7872715
    Abstract: A liquid crystal display device may include a first substrate; a second substrate; a first polarizing plate on the first substrate; a second polarizing plate arranged on the second substrate, and so that a direction of an absorption axis of the second polarizing plate being perpendicular to a direction of an absorption axis of the first polarizing plate; a liquid crystal layer arranged between the first substrate and the second substrate; a color filter layer arranged between the liquid crystal layer and the first or the second substrate, the color filter layer having a plurality of pixels of two or more colors. The retardation thin film has in-plane birefringence index satisfying 0.75??n[fr]/?d[fr]?1.35 for a region corresponding to a reflection part of a pixel and satisfying ?n[t]<1.2 ×10?3 for a region corresponding to a transmission part of a pixel.
