Abstract

A first polarization plate 21 is adhered to one surface of a liquid crystal unit 10 through a first adhesive agent layer 31 in a way that an absorbing axis 21A is in parallel to the longitudinal side 10A of the liquid crystal unit 10. A second polarization plate 22 is adhered to another surface of the liquid crystal unit 10 through a second adhesive agent layer 32 in a way that an absorbing axis 22A is orthogonal to the absorbing axis 21A of the first polarization plate, thereby obtaining a liquid crystal panel. At least one of the adhesive agent layers 31, 32 is formed by an adhesive agent composition, the adhesive agent composition containing 0.01 to 5 parts by weight of a crosslinking agent (B) relative to 100 parts by weight of an acrylic resin (A), in which the acrylic resin (A) has a weight average molecular weight of 1 to 2 million, and the molecular weight distribution is 3 to 7, obtained by co-polymerizing 80 to 96 percent by weight of (metha)acrylic acid alkyl ester, 3 to 15 percent by weight of a monomer containing aromatic rings, and 0.1 to 5 percent by weight of a monomer containing polar functional groups. The gel fraction of the adhesive agent layer is 60 to 99 % by weight. The liquid crystal panel of the invention is laminated by a pair of polarization plates at two surfaces via the adhesive agent layers, such that white spotting can be inhibited even if the sizes become larger.
