Abstract

According to one embodiment, a display device includes a display panel including a reflective layer, a liquid crystal element opposing the display panel and a controller that controls the liquid crystal element. The liquid crystal element includes a first substrate, a second substrate, a liquid crystal layer, a first control electrode, a second control electrode, a third control electrode, and a fourth control electrode. The controller applies a first voltage for forming a first lens of a first shape, to the first control electrode and the second control electrode, and a second voltage for forming a second lens of a second shape, to the third control electrode and the fourth control electrode. The first shape is different from the second shape.
