    摘要： An optical deflection device includes an optical deflection element having a pair of transparent boards arranged in a mutually opposing manner. A liquid crystal layer is filled between the boards and forms a chiral smectic C phase. An orientation film orients liquid crystal molecules in the liquid crystal layer in a substantially perpendicular direction with respect to the liquid crystal layer. Electrodes generate an electric field in a substantially parallel direction with respect to the liquid crystal layer. A first voltage application part applies, to the electrodes, an ac voltage of a deflection frequency switching the optical deflection direction of the optical deflection element. A second voltage application part applies, to the electrodes, an ac voltage of a higher frequency than the deflection frequency. A stop process part causes the second voltage application part to apply the ac voltage of the higher frequency than the deflection frequency after causing the first voltage application part to apply the ac voltage of the deflection frequency, when stopping an operation of switching the optical deflection direction of the optical-deflection element.

    摘要： An insulating layer is formed on a plurality of electrodes formed on a plastic film substrate, the insulating layer having a plurality of electrode connecting holes formed therein. Electrodes of the plurality of electrodes are selectively connected to an external circuit via respective ones of the plurality of connecting holes. Conductive color filter layers are formed on the thus-connected electrodes by an electrochemical method. A value obtained as a result of subtracting a width of each one of the plurality of electrode connecting holes from a width of a respective one of the plurality of electrodes is large so that a position of the electrode connecting hole is maintained to correspond to a position of the electrode even when the plastic film substrate expands or contracts maximally.
