Abstract
The access hole for filling the liquid crystal cavity in an LCD having plastic front and rear members is sealed by welding the two members together. Pressure is applied during the weld to insure a good joint. The welding process avoids problems of non-adhesion or poor adhesion associated with the use of epoxy, especially the type of epoxy used for sealing glass LCDs.
