[0038] Such as Figure 7 It shows that the embodiment of the present invention provides a naked-eye 3D display device 100 . See Figure 7 , the glasses-free 3D display device 100 includes a 2D display unit 110 and a liquid crystal slit grating 120 . The 2D display unit 110 includes a pixel array, such as figure 2 or image 3 As shown, each pixel in the pixel array includes a plurality of sub-pixels of different colors alternately arranged along the first direction. The liquid crystal slit grating 120 is disposed on one side of the display surface of the 2D display unit 110 and is opposite to the display surface of the 2D display unit 110 .
[0039] The 2D display unit 110 may be, for example, a liquid crystal display unit, including a backlight unit 111 and a display panel 112 . Wherein, the backlight unit 111 may be a direct type or an edge type backlight unit 111 including LED (Led Emitting Diode) or CCFL (Cold Cathode Fluorescent Lamp) and other light sources. The di...

[0058] The difference between the naked-eye 3D display device 100 provided by the second embodiment of the invention and the first embodiment of the invention lies in the structure of the electrode layer 125 disposed between the first grating substrate 122 and the second grating substrate 123 of the liquid crystal slit grating 120 . In the embodiment of the present invention, such as Figure 13 As shown, the electrode layer 125 includes a first electrode layer 1251 and a second electrode layer 1252, the first electrode layer 1251 is disposed on the opposite side of the first grating substrate 122 and the second grating substrate 123, The second electrode layer 1252 is disposed on a side of the second grating substrate 123 opposite to the first grating substrate 122 .
[0059] In this example, see Figure 13 , the first electrode layer 1251 includes a plurality of strip-shaped electrodes arranged at intervals and parallel to each other, and the second electrode layer 1252 incl...

[0069] The naked-eye 3D display device 100 provided by the third embodiment of the invention differs from the first embodiment of the invention in that the structure of the electrode layer 125 disposed between the first grating substrate 122 and the second grating substrate 123 of the liquid crystal slit grating 120 is different. In the embodiment of the present invention, such as Figure 13 As shown, the electrode layer 125 includes a first electrode layer 1251 and a second electrode layer 1252, the first electrode layer 1251 is disposed on the opposite side of the first grating substrate 122 and the second grating substrate 123, The second electrode layer 1252 is disposed on a side of the second grating substrate 123 opposite to the first grating substrate 122 .
[0070] In this example, see Figure 18 , the first electrode layer 1251 includes a plurality of parallelogram electrodes, and the second electrode layer 1252 includes a plurality of parallelogram electrodes. Two ...
