摘要:
A display apparatus comprising a modulator sandwiched between two polarizers. The modulator includes a plurality of light transmitting windows arranged in a matrix on a substrate having an electrooptical effect. Each window is associated with an electrode pair for forming an electric field across the window. One scanning line electrically interconnects first electrodes in the electrode pairs of the windows arranged in a row. One signal line electrically interconnects second electrodes in the electrode pairs of the windows arranged in a column. A scanning circuit sequentially and individually electrifies the scanning lines. A signal circuit is operable in response to a synchronizing signal received from the scanning circuit and display information for electrifying one of the signal lines connected to the electrode pair of a selected window for forming an electric field. An electric field control circuit provides zero potential difference in the electrode pairs of the other windows than the selected window.
