    摘要： A liquid crystal display device according to the present invention includes a rear light source device, a rear polarizing plate, a liquid crystal cell including liquid crystal molecules that are substantially perpendicularly aligned during black display, and a front polarizing plate, which are provided in the stated order, wherein: an absorption axis of a polarizer of the rear polarizing plate is perpendicular to an absorption axis of a polarizer of the front polarizing plate; and condensed light in which a half-value angle in a direction perpendicular to the absorption axis of the polarizer of the rear polarizing plate is smaller than a half-value angle in a direction parallel to the absorption axis of the polarizer of the rear polarizing plate enters the rear polarizing plate. According to the present invention, a liquid crystal display device having an excellent front contrast ratio, and a polarizing plate with a condensing element for realizing the liquid crystal display device having the excellent front contrast ratio may be provided.

    摘要： A method of producing a roll of a continuous web of an optical film laminate, usable in a process of laminating an optical film sheet including a polarizing film and formed to a size corresponding to that an optical panel to a surface of the optical panel being fed to a lamination position, is disclosed. The polarizing film is prepared by subjecting a laminate including a thermoplastic resin substrate and a PVA type resin layer formed on the substrate, to uniaxial 2-stage stretching to reduce a thickness of the PVA type resin layer to 10 μm or less, and causing a dichroic material to be absorbed in the PVA type resin layer. A carrier film is releasably attached to the continuous web of optical film laminate including the polarizing film, through an adhesive layer. A defect inspection is performed for the optical film laminate and the adhesive layer.
