Disclosed are a slit grating and a preparation method therefor, and a display device. In the slit grating, a liquid composite layer composed of a light-shading liquid (3) and a light-transmitting liquid (4) which are incompatible are used to replace a liquid crystal molecule layer, and a strip-shaped electrically controlled dielectric sublayer (2) corresponding to a pixel unit is arranged, the distribution of the light-shading liquid (3) and the light-transmitting liquid (4) is controlled by using the feature of the strip-shaped electrically controlled dielectric sublayer (2) being hydrophilic or hydrophobic to the light-shading liquid (3) through electrification. During 3D display, a slit grating is formed; and during 2D display, a region corresponding to the pixel unit of a display panel is all-transparent, so that a two-dimensional/three-dimensional switchable function can be realized. Since a polaroid structure of a liquid crystal slit grating is not needed, the utilization rate of light rays is increased. Meanwhile, the requirements on a fluid material layer and on the box thickness are also lower than those of the liquid crystal slit grating, so that the technological process is relatively simple. |
