POLARIZATION PLATE

摘要

A polarization plate that realizes high adhesion between polarizer and protective film, ensuring stable optical performance of the polarizer against influences from moisture, etc. There is provided polarization plate (4,12) comprising polarizer (2,10) and, superimposed on at least one major surface thereof, protective film (3,11) produced by hardening of an energy radiation hardenable composition, wherein the energy radiation hardenable composition contains: (1) energy radiation polymerizable compound having a bridged hydrocarbon group, a bisphenol group, a neopentyl glycol group, a trimethylolpropane group or a pentaerythritol group, and (2) hydrolyzate of a silane coupling agent. Liquid crystal display device (9) is built by superimposing this polarization plate (4,12) on at least one major surface of liquid crystal panel (1).
