Abstract: Disclosed is a naked-eye three-dimensional display device, which is from top to bottom sequentially provided with a first substrate, a light-emitting layer, a second substrate, a first indium tin oxide (ITO) electrode layer, a three-dimensional prism liquid crystal layer, a second ITO electrode layer and a third substrate. One side of the first substrate facing the light-emitting layer is provided with thin film transistors arranged in a matrix form. Since the first ITO electrode layer is disposed directly on the second substrate, a substrate and a transparent photoresist layer are not used. Thus, the weight of the device is reduced, and the display brightness and the alignment accuracy are improved. When liquid crystal prism electrode units of the first ITO electrode layer and display regions of pixel units are configured to overlap with each other, the influence of transmitted light on naked eye 3D display can be avoided and the 3D display effect is improved.
