ABSTRACT:
The invention provides a high quality liquid crystal panel with low non-uniformity by enveloping a pair of glass substrates sandwiching an uncured thermosetting seal member with heat-resistant metal sheets, bringing the insides of the sheets into a substantially hermetically closed state to decompress the space around the substrates, pressing the glass substrates and the seal member by a pressure difference from the atmospheric pressure in a predetermined space created by the enveloping sheets, heating the sheets, the glass substrates and the seal member with a heater disposed at a position remote from the sheet and curing the seal member, and maintaining the gap between the pair of glass substrates to prevent non-uniformity of the gap between the pair of glass substrates constituting the liquid crystal panel.
