1. An electro-optical device comprising:

  • a pair of substrates;

    an electro-optical modulating layer provided between said substrates;

    a column control line provided on one of said substrates;

    two row control lines R1 and R2 provided on said one of said substrates;

    an electrode provided on said one of said substrates between said two row control lines;

    a first p-channel transistor P1 and a first n-channel transistor N1 which are provided on said one of said substrates and connected to said column control line at gate terminals of the transistors P1 and N1, and to said electrode at one of source and drain terminals of said first p-channel transistor P1 and at one of source and drain terminals of said first n-channel transistor N1 ;

    a second p-channel transistor P2 provided on said one of said substrates and connected to the row control line R1 at one of source and drain terminals of the transistor P2, to the row control line R2 at a gate terminal of the transistor P2, and to the other one of the source and drain terminals of said first n-channel transistor N1 at the other one of the source and drain terminals of said second p-channel transistor P2 ; and

    a second n-channel transistor N2 provided on said one of said substrates and connected to the row control line R2 at one of source and drain terminals of the transistor N2, to the row control line R1 at a gate terminal of the transistor N2, and to the other one of the source and drain terminals of said first p-channel transistor P1 at the other one of the source and drain terminals of said second n-channel transistor N2.
