| 요약정보 |
The invention relates to an optical device and a method for manufacturing the same. More specifically, the invention relates the following optical device. The optical device including a lower electrode; an insulating film provided on the lower electrode; upper electrodes provided on the insulating film; and variable conductivity patterns provided to be adjacent to the upper electrodes, respectively, on the insulating film. The upper electrodes include first and second electrodes that are alternately provided, a pitch between the first electrodes is identical to a pitch between the second electrodes, the second electrode is provided between the adjacent first electrodes, a distance between one of the adjacent first electrodes and the second electrode is a first length, a distance between another one of the adjacent first electrodes and the second electrode is a second length, and the second length differs from the first length.
