Naked eye three-dimensional (3d) display device

A naked eye three-dimensional (3D) display device, wherein the naked eye 3D display device comprises a display panel and a liquid crystal lens located on a light-emitting side of the display panel;

• wherein
• the display panel comprises:
• a first glass substrate;
• and
• an organic light-emitting diode (OLED) device disposed on a surface of the first glass substrate, the OLED device comprising a transparent cathode metal, and the transparent cathode metal disposed on a portion of the OLED device facing away from the first glass substrate;
• the liquid crystal lens comprises:
• a first thin film package layer covering a surface of the transparent cathode metal;
• a first transparent electrode disposed on a surface of the first thin film package layer;
• a second glass substrate disposed opposite to the first glass substrate;
• a second transparent electrode disposed on a side of the second glass substrate facing the first glass substrate, and coupled to the first transparent electrode;
• and
• a liquid crystal layer disposed between the second transparent electrode and the first transparent electrode;
• multiple metal via holes are defined in the first thin film package layer;
• and
• the first transparent electrode is electrically connected to the transparent cathode metal through the metal via holes.
