<p>PROBLEM TO BE SOLVED: To reduce nonuniformity of transmitted light. SOLUTION: A lower-layer comb-tooth electrode 13 and an upper-layer comb- tooth electrode 17 are arranged as one unit at given intervals while overlapping with each other by severalμm. An electric field is produced by the upper-layer comb-tooth electrode 107 vertically from thereupon. Further, an electric field is produced by the lower-layer comb-tooth electrode 103 from its edge and plane parts. Here, a vertical electric field nearby the upper-layer comb-tooth electrode and lower-layer comb-tooth electrode 103 is produced only on the electrodes and the electric field produced at the edge of the lower-layer comb- tooth electrode 103 is transmitted through insulating film layers 104 and 108, so it is not applied to liquid crystal. No vertical electric field is therefore produced between electrodes to which light is transmitted, so the uniform transmitted light is obtained.</p> |
