Abstract

　本発明は、保存安定性に優れ、硬化時における接着剤自体および接着対象物の変色を抑制することが可能で、硬化速度が大きくかつ良好な接着性を与える光硬化性接着剤、該硬化性接着剤を用いた偏光板およびその製造方法、光学部材、ならびに液晶表示装置を提供する。本発明は、ヨウ素または二色性染料が吸着配向されたポリビニルアルコール系樹脂フィルムからなる偏光子に保護膜を貼合するための接着剤であって、分子中に２個以上のエポキシ基を有しかつ該エポキシ基のうちの少なくとも１個が脂環式エポキシ基であるエポキシ樹脂（Ａ）の１００質量部と、分子中に２個以上のエポキシ基を有しかつ脂環式エポキシ基を実質的に有さないエポキシ樹脂（Ｂ）の５～１０００質量部と、光カチオン重合開始剤（Ｃ）の０．５～２０質量部と、を含む光硬化性接着剤に関する。
