Referring to fig. 9 to 12, the embodiment of the application further provides a 2D/3D switchable display device 100, which includes a display panel 120 and a liquid crystal lens module 110, wherein the liquid crystal lens module 110 is disposed on the light emitting side of the display panel 120, and the liquid crystal lens module 110 is the liquid crystal lens module 110 in any of the above embodiments.
The display panel 120 may be a liquid crystal display panel or an OLED (Organic Light-Emitting Diode) display panel, for example.
Referring to fig. 9 to 11, the display panel 120 may include a third liquid crystal layer 121 and a pixel electrode 122, wherein the pixel electrode 122 and the third electrode 21 in the liquid crystal lens module 110 together control the rotation of liquid crystal molecules in the third liquid crystal layer 121, that is, the third electrode 21 and the second sub-electrode 23 together control the rotation of liquid crystal molecules in the second liquid crystal layer 22 in the liquid crystal lens module 110, and the pixel electrode 122 together control the rotation of liquid crystal molecules in the third liquid crystal layer 121 in the display panel 120, so as to reduce the number of common electrodes, thereby saving the manufacturing process and reducing the manufacturing cost.
Illustratively, the material of the third liquid crystal layer 121 may be a positive liquid crystal material or a negative liquid crystal material.
Illustratively, the material of the pixel electrode 122 may be a transparent conductive metal oxide, such as ITO (indium tin oxide) or the like.
