Abstract: A display device includes glasses disposed to correspond to a display area of a lens. A display panel emits display light. A reflective member reflects the display light emitted from the display panel in a direction towards the glasses. A light source unit emits near-infrared light towards a user's eyes for tracking a user's eyes. A protective filter includes a liquid crystal layer. The protective filter blocks a portion of a light path of the near-infrared light emitted towards the user's eyes from the light source unit. A processor controls the liquid crystal layer. The liquid crystal layer forms a blocking area blocking the portion of the light path of the near-infrared light emitted towards the user's eyes and a transmission area that does not block the light path of the near-infrared light emitted towards the user's eyes.
