Abstract
A liquid crystal display device is one in which unevenness of display, spots, etc. caused by lowering of voltage retention by impurity ions are sufficiently eliminated and reliability of long time/long term use is improved. A liquid crystal display device is formed with a liquid crystal layer between a first substrate and a second substrate configured via a seal, wherein the liquid crystal display device includes electrodes on the liquid crystal layer side of a non-display region of the first substrate and/or the second substrate, and the potentials of the electrodes are substantially the same.
