TRANSMISSIVE LCD

摘要

PURPOSE: A transmissive LCD(Liquid Crystal Display) is provided to rotate nematic LC molecules vertically when driving voltage is fed to a pixel electrode and a counter electrode, as well as to reduce irregularity in alignment of the nematic LC molecules. CONSTITUTION: A transmissive LCD consists of: an LC cell(10) having plural nematic LC molecules(12); an input alignment layer(21) and an output alignment layer(23) arranged at both sides of the LC cell; an input substrate(31) and an output substrate(33) of transparent material arranged with a cell gap(d) between the two alignment layers; plural couples of pixel electrodes(51) and counter electrodes(53) formed on the input substrate; and a polarizer(41) and an analyzer(43) arranged on the two substrate respectively. The input alignment layer aligns the nematic LC molecules parallel in a rubbing direction(R1) to have a pre-tilt angle. The output alignment layer aligns the nematic LC molecules vertically to have a pre-tilt angle. Herein, the rubbing direction has a parallel angle of 45-90 degrees to a fringe field generated by the pixel electrode and the counter electrode.
