An electro-optical display device in accordance with the present invention has a plurality of picture elements arranged in a matrix form, and each of the picture elements is composed of an electro-optical material layer and a switching element which is electrically connected to the material layer in a series form. A data voltage is written on the electro-optical material layer via the switching element for a writing period. A reference voltage is applied to the other end of a connection to which the data voltage is applied, and the reference voltage is inverted alternately together with the data voltage for each predetermined period, by which the electro-optical material layer is ac driven. The value of the data voltage is controlled to coincide approximately with that of the reference voltage for the periods other than the writing period.
An electro-optical display device comprising:
A method for driving a display device comprising a display cell having data electrodes arranged in parallel with each other and a plasma cell producing discharge channels formed at right angles to said data electrodes, in which the data voltage applied to said data electrodes is inverted alternately together with a predetermined reference voltage, and the value of said data voltage coincides substantially with that of said reference voltage for the periods other than the period for writing said data voltage.
