DISPLAY APPARATUS

A display apparatus includes a backlight unit including a first light guide plate and a first light source element, a liquid crystal display panel located on an upper surface of the first light guide plate and including a sensing area, and an optical module located on a lower surface of the first light guide plate and including a reflective structure having an inclined surface. The display apparatus further includes a second light source element, a optical sheet, and an optical element, wherein the inclined surface of the reflective structure overlaps the sensing area of the liquid crystal display panel, and the second light source element and the optical element are located on different surfaces of the reflective structure to minimize a luminance deviation between the active area and the sensing area of the display apparatus.
