ABSTRACT:
A projection type liquid crystal display device which displays an image on a screen by projecting the light emitted from a light source and passing through a liquid crystal display element onto said screen, said element having first and second liquid crystal panels, a plurality of signal electrodes which are parallel with each other; and scanning electrodes which are parallel with each other and are orthogonal to said signal electrodes, said signal electrodes and scanning electrodes being disposed for sandwiching each said liquid crystal layer therebetween and modulating the strength of light that has been transmitted through each portion of said liquid crystal layer, wherein the signal electrodes arranged in parallel on the first liquid display panel are separated into two parts at the middle of upper half display portion, and the signal electrodes arranged in parallel on the second display panel are separated into two parts at the middle of lower half display portion.
