Abstract
According to one embodiment, a display system includes an external light sensor, a display panel, a viewing angle control panel including a liquid crystal layer containing liquid crystal molecules twist-aligned, configured such that a drive voltage applied to the liquid crystal layer is controlled based on an external light intensity detected by the external light sensor, and a polarization axis rotation element disposed between the viewing angle control panel and the display panel. The drive voltage when the external light intensity is less than a threshold value is greater than the drive voltage when the external light intensity is greater or equal to than the threshold value.
