Abstract
A method of manufacture of a liquid crystal display panel is described whereby a fixed number of drops of liquid crystal, or a mixture of liquid crystal and spacers, are dropped at various positions on an electrode face of at least one of a pair of substrates, with the amount of liquid crystal in each of the drops being predetermined to a very high degree of accuracy. One of the substrates is then superposed on the other, under a condition of reduced air pressure, then under a condition of normal atmospheric pressure, mutual lateral position adjustment of the substrates is performed to a high degree of precision.
Claims5
A method of manufacture of a liquid crystal display panel comprising successive steps of:
- forming a sealing member on at least one of respective electrode surfaces of a pair of substrates;
- forming at least one drop of a liquid crystal material upon at least one of said electrode surfaces of the pair of substrates;
- superposing one of said pair of substrates upon another one of said pair with said respective electrode surfaces disposed mutually opposing, under a condition of reduced ambient air pressure;
- under a condition of normal atmospheric air pressure, executing mutual lateral position adjustment of said pair of substrates;
- and
- executing hardening processing of said sealing member.
A method of manufacture of a liquid crystal display panel comprising successive steps of:
- forming a sealing member on at least one of respective electrode surfaces of a pair of substrates;
- forming at least one drop of a liquid crystal material upon at least one of said electrode surfaces of the pair of substrates, by means of a liquid crystal dropping apparatus having a plunger and means for precisely driving said plunger by a fixed degree of movement to thereby eject a fixed amount of said liquid crystal material from a tip portion of said liquid crystal dropping apparatus, said tip portion being in contact with said at least one of the electrode surfaces;
- superposing one of said pair of substrates upon another one of said pair with said respective electrode surfaces disposed mutually opposing, under a condition of reduced ambient air pressure;
- under a condition of normal atmospheric air pressure, executing mutual lateral position adjustment of said pair of substrates;
- and
- executing hardening processing of said sealing member.
