Optical device

An optical device comprising:

• a first liquid crystal cell;
• and
• a second liquid crystal cell overlapped with the first liquid crystal cell;
• wherein each of the first liquid crystal cell and the second liquid crystal cell includes:
• a first substrate arranged with a plurality of first electrodes having a first pattern having a first bending point;
• a second substrate arranged with a plurality of second electrodes having a second pattern having a second bending point;
• a first alignment film arranged on the first electrode;
• a second alignment film arranged on the second electrode;
• and
• a liquid crystal layer between the first substrate and the second substrate,
• wherein the plurality of first electrodes is arranged with the alignment direction of the first bending point inclined at a predetermined angle to the first direction,
• wherein the plurality of second electrodes is arranged with the alignment direction of the second bending point inclined at a predetermined angle with respect to a second direction perpendicular to the first direction,
• wherein the arrangement direction of the first bending point and the arrangement direction of the second bending point intersect without being perpendicular,
• wherein the first substrate and the second substrate are arranged with the first electrode and the second electrode facing each other,
• wherein the plurality of first electrodes and the plurality of second electrodes overlap in a plan view,
• wherein the arrangement direction of the first bend point in the first liquid crystal cell and the arrangement direction of the first bend point in the second liquid crystal cell are different from each other, and the arrangement direction of the second bend point in the first liquid crystal cell and the arrangement direction of the second bend point in the second liquid crystal cell are different from each other,
• wherein an alignment direction of the first alignment film is perpendicular to the first direction and an alignment direction of the second alignment film is perpendicular to the second direction, and
• wherein the alignment direction of the first alignment film intersects so as not to be perpendicular to the arrangement direction of the first bend point in the first liquid crystal cell and the arrangement direction of the first bend point in the second liquid crystal cell and the alignment direction of the second alignment film intersects so as not to be perpendicular to the arrangement direction of the second bend point in the first liquid crystal cell and the arrangement direction of the second bend point in the second liquid crystal cell.
