Disclosed are a display apparatus and a light control method thereof, in which the display apparatus including a display panel, a light source unit, an illumination unit to illuminate the display panel with light emitted from the light source unit, and a projection unit to project the light from the display panel in a predetermined direction includes: a light sensor which is provided between the light source unit and the illumination unit; and a light controller which corrects brightness of light sensed by the light sensor on the basis of reflective characteristics of the display panel. With this configuration, the quantity of light is prevented from decreasing so as to prevent the brightness of an image from decreasing.
