For liquid crystal lens unit L1, occlusion part 806 is arranged at the side 8011 of first substrate 801 away from the first electrode 803, with the first electrode 8032 shared just to setting, and consistent with the size shape of the first electrode 8032 shared.Under 3D state, do not power up to liquid crystal slit grating, its liquid crystal molecule does not twist, light cannot pass through liquid crystal slit grating, liquid crystal lens unit L1 edge dull thread passes through, for eliminating the crosstalk caused when this part light shows bore hole 3D, reducing liquid crystal lens unit L1 edge due to the violent impact on display effect of light path fluctuation, improving image quality.
Voltage is applied when not giving the first electrode 803 and the second electrode 804, liquid crystal layer 805 does not form liquid crystal lens unit, now the duty of liquid crystal lens is 2D state, now, power up to liquid crystal slit grating, its liquid crystal molecule twists, and light passes through liquid crystal slit grating, do not affect 2D and show state, avoid the restraining mass striped when 2D shows.
Understandable, insulation transparent material 808 can also be set between adjacent occlusion part 806, while not affecting light transmition, play the effect supporting occlusion part 806.
Although the embodiment disclosed by the utility model is as above, the embodiment that described content just adopts for the ease of understanding the utility model, and be not used to limit the utility model.Technician in any the utility model art; under the prerequisite not departing from the spirit and scope disclosed by the present invention; any amendment and change can be done what implement in form and in details; but scope of patent protection of the present utility model, the scope that still must define with appending claims is as the criterion.
