Abstract:
A liquid crystal display of homeotropic alignment mode having a multi-domain comprising:an upper and a lower substrates opposing each other with a selected cell gap;a liquid crystal layer sandwiched between said substrates and composed of a plurality of liquid crystal molecules;a first driving electrode and a second driving electrode both extended in parallel in a first direction and formed at inner surface of the lower substrate with a selected distance; anda third driving electrode and a fourth driving electrode both extended in parallel in a second direction which is substantially perpendicular to the first direction and both formed at inner surface of the upper substrate with a selected distance,wherein long axes of the liquid crystal molecules are arranged perpendicular to the substrates in the absence of electric field between the electrodes, and in the presence of electric field, the long axes of the liquid crystal molecules are tilted with respect to the center of the electric field so that the long axes of the liquid crystal molecules are arranged parallel to the electric field,wherein the cell gap is smaller than the distances between the first electrode and the second electrode and between the third electrode and the fourth electrode, andwherein an equivalent voltage is applied to the first and the third electrodes, however the voltage applied to the second and the fourth electrodes has voltage difference with the voltage applied to the first electrode.
