Abstract: The disclosure relates to a 3D display device. The 3D display device includes a display panel and an electrochromic grating that is located on a light output side of the display panel; wherein the electrochromic grating comprises: a first transparent electrode layer, an electrochromic layer, a solid electrolyte layer and a second transparent electrode layer that are overlapped on a substrate of the display panel in sequence. As the solid electrolyte layer is used replacing the process in prior art that an upper and lower glasses substrates are used to package the electrochromic grating and thus avoiding complex packaging process, the 3D display device can be thinned. Further, as the electrochromic grating is directly formed on the substrate of the display panel, alignment between the electrochromic grating and the sub-pixels in the display panel can be more simple and accurate.
