Abstract
Provided are an optical device and a method of manufacturing the optical device including a lower electrode; an insulating layer provided on the lower electrode; upper electrodes provided on the insulating layer; and variable conductivity patterns provided to be adjacent to the upper electrodes, respectively, on the insulating layer. 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.
