A grey tone display and a driving method are described. The display
comprises a light influencing layer, an electrode pad located adjacent to
the layer at one side of the layer in order to define a pixel in the
layer, an n-channel field effect transistors connected to the electrode
pad at its source terminal, a p-channel field effect transistors
connected to the electrode pad at its source terminal, a first control
line connected to the drain terminal of the n-channel field effect
transistor, a second control line connected to the drain terminal of the
p-channel field effect transistor, a third control line connected to the
gate terminals of the n-channel field effect transistor and the p-channel
field effect transistor, and a control circuit for supplying control
signals to the first, second and third control lines. By this
configuration, the voltage of the electrode pad can be arbitrarily
controlled by adjusting the input level at the gate terminals.
