ABSTRACT:
A method of making a light-influencing liquid crystal display wherein no spacers are placed in the display regions, in order to improve the contrast of the liquid crystal display. The method comprises the steps of preparing a first and second substrate, forming a first plurality of pixel electrodes on the first substrate, forming a plurality of thin film transistors (TFT) on the first substrate, forming a second plurality of pixel electrodes on the second substrate, forming a plurality of black stripes and spacers on the second substrate in a predetermined pattern, securing the substrates together with the first plurality of electrodes facing the second plurality of electrodes and with the spacers between the substrates, and applying light-influencing display material between the substrates.
