Claims

[Scope of utility model registration request]

a glass plate having a plurality of segment electrode groups;
A glass plate having a plurality of common electrode groups is disposed so that the electrode groups are orthogonal to each other, a liquid crystal material is sealed between both glass plates, and a scanning voltage is selectively applied between these electrodes. In a dot matrix type liquid crystal display device that performs a dot matrix display by combining intersection points, an OFF voltage is applied between both sides of the segment electrode group and both sides of the common electrode group. A liquid crystal display device comprising dummy electrodes to which the same voltage is applied.
