发明名称 POLARIZING PLATE AND POLARIZING PLATE WITH TACKY ADHESIVE
摘要 <P>PROBLEM TO BE SOLVED: To provide a polarizing plate which is formed by using general protective films or angle-of-view improving films and is small in void even if a relatively hard tacky adhesive is used and to provide a polarizing plate with a tacky adhesive imparted with a tacky adhesive layer thereto. <P>SOLUTION: The polarizing plate which is formed by laminating the protective films consisting of a resin different from a polyvinyl alcohol (PVA) resin on both surfaces of the polarizing film consisting of the PVA resin adsorbed and oriented with dichromatic dyestuffs and having a thickness over 10 &mu;m and below 20 &mu;m is provided. The polarizing plate with the tacky adhesive which is formed by imparting the tacky adhesive layer of &le;30 &mu;m in the deviation value after 100 seconds and &le;50 &mu;m in the deviation value after 1,000 seconds in a deviation test to at least one surface of the polarizing plate and which is &le;3.5 in the ratio K<SB>2</SB>/K<SB>1</SB>of the brightness K<SB>1</SB>in the central part of the polarizing plate and the brightness K<SB>2</SB>in the central edge segment on the long side of the polarizing plate when two sheets of the polarizing plate each sized 200 mm&times;150 mm are superposed in crossed Nicols is also provided. <P>COPYRIGHT: (C)2003,JPO
