ABSTRACT:
A process for the manufacture of a liquid crystal container for a liquid crystal display element, which process comprises the steps of applying a low-melting glass frit paste to at least one of a pair of glass substrates, subjecting this glass substrate to primary firing in an open condition in which the paste is in no contact with any matters, and while holding the pair of the glass substrates in their accurate relative positions, subjecting the glass substrates to secondary firing to seal the pair of the glass substrates with the glass frit. The process preferably comprises the step of applying, prior to the step of secondary firing, a low-melting glass frit paste to one of the glass substrates so as to reliably hold the pair of the glass substrates in the accurate relative positions.
