Abstract
The invention relates to a special structure of an electro-optic cell or pixel in a liquid crystal screen that improves the transmittance compared with prior-art screens. The pixel is formed by two substrate layers, on one of which there is a pixel electrode and on the other a counter-electrode, with a layer of liquid crystal molecules between these electrodes, in which the counter-electrode is divided into two parts by a groove, wherein a non-zero polarization voltage is applied between the electrode and the counter-electrode when the pixel is not addressed.
