Claim Text:
1. A display device comprising liquid crystal lens cells are arranged on a display panel, wherein the liquid crystal cells have a TN type liquid crystal, which is sandwiched between a first substrate and a second substrate and whose twist angle is 90 degrees, wherein a first electrode is formed in a flat solid manner on a side of the liquid crystal of the first substrate, and a plurality of second electrodes are in a stripe pattern as seen in plane on a side of the liquid crystal of the second substrate, wherein the plurality of second electrodes extend in a first direction and arranged in a second direction formed on a same layer; wherein a plurality of liquid crystal lenses are formed in the liquid crystal cells, and each of the plurality of liquid crystal lenses is formed using the first electrode and at least three of the plurality of second electrodes, wherein each of the at least three of the plurality of second electrodes is applied with different voltages from each other, wherein the plurality of second electrodes exist at a boundary between a first liquid crystal lens and a second liquid crystal lens, and wherein the plurality of the second electrodes at the boundary are applied with a maximum voltage among the different voltages.
