Abstract: A display device for switching a viewing angle, can include a display panel, a polarizing plate disposed on the display panel, a light path control cell disposed on the polarizing plate and including a liquid crystal layer, and a light path conversion film disposed on the light path control cell and including a plurality of molecules including a polarization alignment dye. An absorption axis of the polarizing plate can be substantially perpendicular to an absorption axis of the light path conversion film. The display device can switch to a shared mode or a shielding mode depending on whether or not a voltage is applied to the light path control cell, thereby providing the display device that switches its viewing angle effectively.
