Patent ID: 8018482

Claim:
A three-dimensional display device comprising: an image display unit having a first resolution; and a light control unit facing the image display unit, wherein the light control unit comprises a first substrate, and a second substrate facing the first substrate, a 2-viewpoint electrode layer and a multi-viewpoint electrode layer located between the first and second substrates, wherein the 2-viewpoint electrode layer and the multi-viewpoint electrode layer are configured to respectively provide stereoscopic images having a second resolution and a third resolution that are both different from the first resolution, and a liquid crystal layer located between the first and second substrates, wherein the 2-viewpoint electrode layer comprises: first electrodes and second electrodes alternately and repeatedly arranged with a first pitch; a first connection electrode electrically connecting the first electrodes to each other; a second connection electrode electrically connecting the second electrodes to each other; first rows on which the first and second electrodes are alternately and repeatedly arranged in a pattern; and second rows that are alternately and repeatedly arranged with the first rows, the first and second electrodes being formed on the second rows in a pattern that is opposite to the pattern of the first rows, and wherein the multi-viewpoint electrode layer comprises: third electrodes and fourth electrodes alternately and repeatedly arranged with a second pitch, the second pitch being larger than the first pitch; a third connection electrode electrically connecting the third electrodes to each other; a fourth connection electrode electrically connecting the fourth electrodes to each other; third rows on which the third and fourth electrodes are alternately and repeatedly arranged in a pattern; and fourth rows that are alternately and repeatedly arranged with the third rows, the third and fourth electrodes being formed on the fourth rows in a pattern that is opposite to the pattern of the third rows.
