Abstract
An elastic pressure sheet that is good in durability against liquid crystals and the like and is good in slipperiness and a process of manufacturing a liquid crystal display plate using the same are disclosed. The elastic pressure sheet comprises an elastic layer having elastic restoring force; hot-melt adhesive layers formed on the both surfaces of the elastic layer; a barrier layer formed on the outer surface of each of the adhesive layers and capable of preventing bleeding of the hot-melt adhesive layer; and a porous layer comprising ultrahigh molecular weight polyethylene, formed on the outer surface of each of the barrier layers.
