Abstract: A stereoscopic image display device including a rear barrier and a parallax unit and thus having highly improved brightness is disclosed. The stereoscopic image display device includes a rear barrier disposed on a bottom surface of a display panel, a parallax unit disposed on a top surface of the display panel, and a light collecting unit disposed between the rear barrier and a backlight unit. Here, the light collecting unit collects light incident from the backlight unit in an open region of the rear barrier to improve brightness of the stereoscopic image display device.
