1. A method of injecting a liquid crystal material, comprising the steps of:
- disposing a liquid crystal material on one substrate (S1) for constituting a pair of substrates; and
disposing another substrate (S2) for constituting the pair of substrate above the substrate (S1), and attaching the pair of substrates S1 and S2 with each other;
wherein, at the time of the attachment of the pair of substrates S1 and S2 together, a closed space B is formed by reservoir means so that the space B is communicated with a space A for liquid crystal display defined by the pair of substrates S1 and S2; and
the liquid crystal material is disposed on the substrate S1 so that the mass of the liquid crystal material provides a volume not larger than the total volume of the spaces (A+B) at the time of the injection of the liquid crystal material.

- 18. A patterned seal member, which is patterned in accordance with a pattern to be disposed on a liquid crystal display substrate and which, when another substrate is attached to each other so as to constitute a pair of substrates, exhibits a function for maintaining a gap between the pair of substrates, wherein, when the pair of substrates are attached to each other, the seal member defines a space A for liquid crystal display between the pair of substrates and a space B to be communicated with the space A.

27. An apparatus for injecting a liquid crystal material, comprising:
-
a chamber for providing a reduced pressure state therein;
a pair of surface plates disposed in the chamber, respectively for being in contact with a pair of the substrates for liquid crystal display;
liquid crystal material-supplying means for disposing a liquid crystal material in a space between the pair of substrates for liquid crystal display; and
temperature control means for controlling the temperature of the pair of surface plates;
wherein at least portion of the pair of surface plates being in contact with the substrates comprise a heat sink material. - View Dependent Claims (28, 29, 30, 31)
