[0048] Such as figure 1 As shown, the nematic liquid crystal layer 4 in the first embodiment includes a plurality of columnar structures 41 connected to the polymer layer 3, and the plurality of columnar structures 41 are arranged in parallel along the length direction of the second substrate 2; An arc-shaped interface 42 is formed at the junction of the column structure 41 and the polymer layer 3 . Wherein, each column structure 41 has two parallel long sides 411 connected to the arc-shaped interface 42 ; the two long sides 411 facing each other of any two adjacent column structures 41 are parallel and contact each other.
[0049] In this embodiment, the nematic liquid crystal layer 4 includes a plurality of columnar structure 41 arranged sequentially along the length direction of the second substrate 2, each columnar structure has two long sides 411 oppositely arranged, and The arc-shaped interface 42 that the polymer layer 3 contacts, for each assembled structure, the arc-...

[0051] Such as Image 6 As shown, the second embodiment differs from the first embodiment above in that in this embodiment, a plurality of column segment structures 41 in the first embodiment above are arranged at intervals along the length direction of the second substrate 2, so that any A space 43 is formed between two adjacent column structures 41 instead of a plurality of column structures 41 being arranged successively, and the polymer layer 3 in this embodiment is provided with a plurality of extensions extending toward the second substrate 2 portion 31 , each extending portion 31 fills a space 43 .
[0052] In this embodiment, part of the polymer layer 3 is stacked above the nematic liquid crystal layer 4, and the extension part 31 is made of the same material as the part of the polymer layer 3, and is combined to form the polymer layer 3, including the extension part 31. The refractive index of each part of the whole polymer layer 3 is the same. When the polarized li...

[0058] Such as Figure 7As shown, in this embodiment, the connecting surface of the nematic liquid crystal layer 4 and the polymer layer 3 is at least partly arranged as an arc segment, that is, the connecting surface of the nematic liquid crystal layer 4 and the polymer layer 3 may include a straight segment , oblique segments, arc segments, etc., but the connecting surface is at least partly arranged as an arc segment, so that when the polarized light is vertically incident on the second substrate 2 and the nematic liquid crystal layer 4, the polarized light can still form a different shape at the arc interface 42. Equal non-zero incident angles, so that the polarized light is refracted and shifted at the arc interface 42, and enters the polymer layer 3 at an exit angle not equal to the incident angle, so that the polarized light can be converged or diverged by the optical film The adjustment is to change the exit angle of the light exiting from the light exit surface 12 of ...
