ABSTRACT:
Disclosed are liquid crystal displays utilizing an electrically insulative hermetic seal for enclosing the liquid crystalline material between the plates of the display. The seal provides a durable improved barrier to the penetration of vapor into the display by being the crosslinked thermoset product of a composition comprising at least one phenoxy resin and at least one epoxy resin in conjunction with a sufficient amount of crosslinking agent to crosslink the composition sufficiently to provide the seal with improved resistance to vapor penetration.
