[0047] Such as Figure 4 As shown, the first embodiment of the present invention provides a liquid crystal lens array 30. The liquid crystal lens array 30 includes a first substrate 31, a second substrate 33 opposite to the first substrate 31, and a substrate interposed between the first substrate and the second substrate. The liquid crystal layer 32 between the two substrates.
[0048] A plurality of first electrodes 310 arranged in an array are disposed on the surface of the first substrate 31 close to the liquid crystal layer 32 . A second electrode 330 is disposed on the surface of the second substrate 33 close to the liquid crystal layer 32 , and the second electrode 330 is a common electrode, that is, a reference electrode. For example, when the first electrode 310 is connected to the positive pole of the driving power, the second electrode 330 is connected to the negative pole of the driving voltage, and when the first electrode 310 is connected to the negative pole of...
