Abstract
In a liquid crystal display cell wherein two glass plates are sealed to a peripheral sealing member provided with a liquid crystal inlet port, the peripheries of the glass plates generally project slightly beyond the periphery of the peripheral sealing member thus forming a shallow groove. Low melting point glass filler is filled in the groove about the inlet port. A metal layer is applied onto the filler and finally a solder layer is applied onto the metal layer to seal the inlet port.
