1. A display device, comprising:
a display panel configured to display a two-dimensional (2D) image and a three-dimensional (3D) image;
a light transmission control unit passing 2D image display light displayed on the display panel in a first linearly polarized light direction, converting a polarized light direction of 3D image display light displayed on the display panel into a second linearly polarized light direction, and emitting the 3D image display light in the second linearly polarized light direction; and
an optical device passing the 2D image display light incident in the first linearly polarized light direction through the light transmission control unit while maintaining optical paths of the 2D image display light and refracting and emitting the 3D image display light of which the polarized light direction is converted into the second linearly polarized light direction through light transmission control unit.
