Abstract: A display device includes a display panel that includes a pixel, a variable light transmission layer disposed on the display panel and that includes liquid crystal molecules, and a lens layer disposed on the variable light transmission layer and that includes lenses and a polarization pattern. The polarization pattern overlaps a boundary area between adjacent lenses. The display device operates in a 2D image mode that provides a 2D image or a 3D image mode that provides a 3D image, and the polarization pattern transmits light when the display device operates in 2D image mode, and blocks light when the display device operates in 3D image mode.
