发明名称 Polarizing plate with optical compensation layer and image display apparatus using the same
摘要 The polarizing plate with an optical compensation layer of the present invention includes: a hardcoat layer; a polarizer; a first optical compensation layer placed so that a slow axis thereof intersects with an absorption axis of the polarizer; and a second optical compensation layer placed so that a slow axis thereof intersects with the absorption axis of the polarizer in the stated order, wherein: the first optical compensation layer provides a substantially ½ retardation with respect to a wavelength of monochromatic light; the second optical compensation layer provides a substantially ¼ retardation with respect to a wavelength of monochromatic light; and the hardcoat layer contains urethaneacrylate, polyol (meth)acrylate, and (meth) acrylic polymer having an alkyl group containing at least two hydroxyl groups. The polarizing plate with an optical compensation layer of the present invention may suitably be used for various image display apparatuses (such as a liquid crystal display apparatus and a self-luminous display apparatus).
