    • PROBLEM TO BE SOLVED: To lessen the flicker and image persistence to be induced by the charges by the impurity ions accumulating at the boundary of a liquid crystal layer by forming spacers which are disposed in a liquid crystal layer and maintain the thickness of the liquid crystal layer so as to have electrical conductivity.
      SOLUTION: The liquid crystal display device is provided with a liquid crystal display element having the liquid crystal layer 1, transparent first electrode groups (column electrodes) 2 which are arranged on the first surface side, i.e., front surface side of the liquid crystal layer 1 and second electrode groups for scanning which are arranged to face the second surface side, i.e., rear surface side of the liquid crystal layer 1 and form a plurality of plasma discharge channels formed in a direction orthogonal the first electrode groups 2. The liquid crystal display element is provided with the spacers 13 for maintaining the thickness of the liquid crystal layer 1 within the liquid crystal layer 1. The spacers have the electrical conductivity. An alignment layer 14 and a dielectric sheet 15 are disposed on the rear surface side of the liquid crystal layer 1. A conductive thin film 16 having the adequate electrical conductivity is disposed between the alignment layer 14 and the dielectric sheet 15.
