Abstract
An active matrix LCD device has a plurality of pixel elements arranged in a matrix for display. The electric field generated between the pixel electrode and the common electrode is diagonal to the normal of the surface of the electrodes. The diagonal electric field is achieved by a slit formed in the TFT panel between the pixel electrodes and the common electrode, or by protrusions formed on the surfaces of the electrodes.
