发明名称
中间基材薄膜及触控面板感测器
摘要
本发明之课题系提供一种自各种角度辨识时可抑制色调偏差之中间基材薄膜及触控面板感测器。;本发明提供一种中间基材薄膜(10),其系支撑经图型化之导电层用之中间基材薄膜(10),其具备:透明基材(11);形成于透明基材(11)之一面(11A)上,折射率为1.47以上且1.57以下,且膜厚为1μm以上之第1透明层(12);形成于第1透明层(12)上,折射率为1.62以上且1.72以下,且膜厚为20nm以上且80nm以下之第1高折射率层(13);及形成于第1高折射率层(13)上,折射率为1.44以上且1.54以下,且膜厚为3nm以上且45nm以下之第1低折射率层(14),将中间基材薄膜(10)之表面之法线方向设为0°,在0°以上且75°以下之范围内边以每5度改变入射角度边自前述第1低折射率层(14)侧对中间基材薄膜(10)照射光,由对各自之正反射方向之反射光求出L*a*b*表色系之a*值及b*值时,a*值之偏差为1.0以内,且b*值之偏差为1.6以内。
