Patent ID: 7505108

Claim:
A method of injecting a liquid crystal material, comprising: disposing a liquid crystal material on a first substrate; disposing a second substrate above the first substrate; and attaching the first substrate and the second substrate to obtain a pair of substrates, wherein, at the time of the attachment, a space B is formed so that the space B communicates with a space A defining an area for a liquid crystal display, the space A being defined by sides of the pair of substrates, and the spaces A and B collectively forming a closed space; the spaces A and B are defined by a patterned seal member disposed on the first substrate, the second substrate or on the first and second substrates; the volume of the space B is based on a volume change between a total volume of the spaces A and B at 25 ° C. and a total volume of the spaces A and B at 100 ° C. as determined based on the thermal expansion coefficients of the liquid crystal material and the seal member at 100 ° C. and 25 ° C.; the liquid crystal material that is disposed on the first substrate has a volume not larger than the total volume of the spaces A and B at the time of disposing the liquid crystal material; and the liquid crystal material is heated prior to being disposed between the pair of substrates, and the temperature of the liquid crystal material is lowered thereafter.
