PLASTIC BASE PLATE UNDERGOING LITTLE DIMENSIONAL CHANGE

摘要

PROBLEM TO BE SOLVED: To provide a plastic sheet suitable particularly for a liquid crystal display panel and having a low rate of change in dimension. SOLUTION: The plastic sheet is characterized in that the dimensional change is -0.02% or below after a heating test wherein the plastic sheet is heated at 150 deg.C for 3 hr in the air and then left to stand at 23 deg.C for 1 hr in the air of a RH of 50%. A gas barrier layer may be provided at least on one side of the plastic sheet to give a laminate. The plastic sheet can be obtained by polymerizing and curing a polymerizable composition comprising mainly a specified bis(meth)acrylate having an alicyclic skeleton.
