Claim:
1. A 3D display device, comprising: a display panel, having a plurality of pixel units in a matrix form defined by gate lines and data lines crossed each other; and a photorefractive crystal member, arranged at a light exiting surface side of the display panel and comprising an electrode structure and a plurality of photorefractive crystals arranged in a row direction of the plurality of the pixel units, the electrode structure generating a plurality of electric field regions corresponding to the plurality of photorefractive crystals in a one-to-one correspondence relationship, each of the photorefractive crystals corresponding to one of the electric field region and being located within a corresponding electrical field region; adjacent columns of photorefractive crystals emitting light for a left eye image/light for a right eye image and the light for the right eye image/the light for the left eye image; wherein the electrode structure comprises a plurality of strip electrodes arranged in the row direction of the pixel units, each strip electrode extends along a column direction of the pixel units, and one of the electric field regions is formed between every two adjacent strip electrodes to allow an electrical field generated by the every two adjacent strip electrodes in operation to be parallel to a light existing surface of the display panel, the photorefractive crystals and the strip electrodes are alternately arranged, and each of the strip electrodes in the electrode structure is attached to row direction sides of the adjacent photorefractive crystal.
