摘要： PURPOSE:To uniformize the thickness of liquid crystal layers facing each other by doping an impurity selectively to regions where the eletrodes of high-polymer films are formed, thereby eliminating steps between parts where the electrodes are formed and parts where the electrodes are not formed. CONSTITUTION:The high-polymer films 9a, 9b are formed on transparent substrates 7a, 7b and the impurity is selectively doped to the regions of the high-polymer films 9a, 9b where the electrodes are formed, by which the electrodes 11a, 11b are formed. A part of the display electrode substrates 6a, 6b obtd. in such are manner are disposed oppositely in such a manner that the surfaces on the side formed with these transparent electrodes 11a, 11b face each other, and a liquid crystal of, for example, a TN type is sealed by a sealing material 13 between a pair of the display electrode substrates 6a and 6b, by which the liquid crystal layer 14 is constituted. The steps between the electrode parts 11a, 11b and the non-electrode parts are eliminated in this way and the thickness of the liquid crystal layer 14 facing these surfaces is uniformized. The liquid crystal display device having a good display grade is thus obtd.
