ABSTRACT:
In a liquid crystal cell, a distance between substrates is fixed to be prevented from increasing without adversely affecting an orientation of liquid crystal material. An adverse effect of undesired charge within a liquid crystal layer is removed to stabilize optical characteristics. A mixture of the liquid crystal material and non-cured resin (i.e., resin forming material and reaction starter) is injected between light-transmissive substrates which form the liquid cell. The non-cured resin is precipitated into the interior of the cell, and the liquid crystal material is orientated. Thereafter, the reaction starter is opened or torn so that the resin is cured to thereby bond the two substrates together with the resin in the form of columns. In this case, the undesired charge within the liquid crystal layer is canceled by the curing effect of the resin concomitant with the opening or tearing of the reaction starter.
