Abstract: According to one embodiment, a polarization conversion element includes a first substrate including a first plane electrode and a first control electrode, a second substrate, and a liquid crystal layer. The first control electrode comprises a first strip electrode, a second strip electrode, a third strip electrode, and a first common electrode. The first strip electrode and the first common electrode are orthogonal to each other, respective extension directions of the first to third strip electrodes are different from each other, and an angle formed by the first strip electrode and the third strip electrode is greater than an angle formed by the first strip electrode and the second strip electrode.

Abstract: According to one embodiment, a display device comprises first and second substrates. The first substrate comprise first and second common electrodes, and a first pixel electrode including a pair of first sides arranged in a first direction. The second common electrode includes first and second trunk portions, and a first branch portion extending from the second trunk portion toward the first trunk portion. The first pixel electrode is located between the trunk portions. The first branch portion overlaps with the first pixel electrode between the first sides. A width of the first pixel electrode between the first sides becomes smaller toward the second trunk portion.
