Abstract: A stereoscopic image display device includes a display panel including a first display area and a second display area. A variable light-transmitting structure is disposed on the display panel and forms a blocking area blocking light from the display panel and a transmitting area transmitting the light from the display panel within the first display area by time division. A lens array is disposed on the variable light-transmitting structure and forms a light field by refracting the light from the display panel.
