ABSTRACT:
A liquid crystal display device having a first transparent substrate, a second transparent substrate and a liquid crystal composition sandwiched between the first and second transparent substrates. The first transparent substrate has a plurality of first main electrodes and a plurality of first auxiliary electrodes extending from the first main electrodes. The second transparent substrate has a plurality of second main electrodes. The second main electrodes are positioned so that the second main electrodes have mutually confronting portions with the first main electrodes, defining main pixels therebetween, and with the first auxiliary electrodes defining auxiliary pixels therebetween. The presence of the liquid crystal composition between the first transparent substrate and the second transparent substrate in the regions of the main pixels and auxiliary pixels allow an image display in the main pixel and auxiliary pixel regions. Second auxiliary electrodes extending from the second main electrodes define further auxiliary pixels with the first main electrodes and still further auxiliary pixels with the first auxiliary electrodes.
