<p>PROBLEM TO BE SOLVED: To provide a liquid crystal display device, having reduced display unevenness due to image sticking and a residual image phenomenon and with high image quality, with respect to a liquid crystal display device using an IPS(in-plane switching) mode, in which a liquid crystal is rotationally operated mostly inside a plane, and displaying is carried out using birefringence of the liquid crystal. SOLUTION: In the liquid crystal display device comprising a pair of substrates of which at least one is transparent, a liquid crystal layer held between the substrates, a pixel electrode, a common electrode and an active element on one of the substrates and alignment control layers and polarizing plates formed on the respective substrates, the image sticking and generation of the residual image are prevented by forming the pair of the alignment control layers with an organic polymer of polyamic acid type or polaymic acid ester type with 60% or higher relative imide ratio or by disposing at least one or more insulation layers between the alignment control layer on the side of the substrate, on which a group of the electrodes is formed and the pixel and common electrodes thereunder so as to flatten the end parts of the electrodes and to moderate the electric field concentrating.</p> |
