<p>PURPOSE:To realize the liquid crystal display device which uses polymer dispersion type liquid crystal having small variance in contrast by setting intervals between picture element electrodes and signal electrodes on a 1st substrate less than intervals between the signal electrodes on the 1st substrate and an electrode on a 2nd substrate. CONSTITUTION:When the thickness of a polymer dispersion type liquid crystal layer 8 is reduced so as to lower a driving voltage, part of a varistor 5 arranged on the 1st substrate 2 contacts the scanning electrode 7 on the 2nd substrate 6 possibly. Here, the interval l1 between a picture element electrode 3 and the signal electrode 4 is shorter than the interval l2 between the signal electrode 4 and scanning electrode 7. Even when the part of the varistor 5 contacts the scanning electrode 7, a varistor voltage between the picture element electrode 4 and scanning electrode 7 is larger than the varistor voltage between the signal electrode 4 and picture element electrode 3, so no current flows to the scaing electrode 7 from the signal electrode 4 through the varistor 5. Therefore, a normal matrix circuit is formed of liquid crystal and varistors 5 and there is no variance in contrast among respective picture elements.</p> |
