Abstract
In a liquid crystal display panel, the shrinkage of an end-scaling material for sticking a pair of substrates together is prevented or relaxed to restrain peeling of the end-sealing material from the substrates, thereby preventing any leakage of a liquid crystal and penetration of contaminants. A liquid crystal display device is assembled by bonding together a pair of substrates, which are opposed to each other across a predetermined gap and at least one of which has an electrode group formed over a surface opposed to the other substrate, with a sealing material along their peripheries excluding a liquid crystal filling port, and then sealing the liquid crystal filling port with an end-sealing material after the filling of the liquid crystal and hermetically sealing the liquid crystal in the gap between both substrates. In the liquid crystal display device, a resin which constitutes the end-sealing material contains particulates of average particle size of 0.1 &mgr;m to 3.5 &mgr;m by at least 1 volume % to 30 volume %, preferably, 1 volume % to 10 volume %.
