In an LCD, there are provided plural kinds of spacers, each kind of spacers having different diameters being arranged at a desired portion. Difference in gap between the displaying portion and the peripheral portion can be compensated by the difference of the sizes of the spacers. Such arrangement of spacers are provided by dropping plural fluids, each including a liquid crystal and spacers on either substrate consecutively such that drops of each fluid are regularly arranged at a desired portion. The gap of the peripheral portion can be made larger than that of the middle portion of the displaying portion. At an edge portion of the displaying portion, spacers having intermediate size may be arranged. The gap between the electrodes at an edge portion may be made larger than that of the middle portion of the displaying portion to compensate affection of resistances of wiring from a drive circuit or unevenness of temperature caused by backlighting. Arrangement of spacers can be obtained by using masks and sprinkling spacers also. Drops of fluids may be mixed on the substrate. Two kinds of spacers may be mixed in a fluid.

Liquid crystal display with curved substrate and several spacer sizes

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.
