Abstract: A liquid crystal lens, a fabrication method thereof and a display device are provided, the liquid crystal lens comprises: a first substrate (1); a second substrate (2), opposed to the first substrate (1); a liquid crystal layer (3), interposed between the first substrate (1) and the second substrate (2); a first transparent electrode layer (5), located on a side of the first substrate (1) close to the liquid crystal layer (3); a planarization layer (6), located on a side of the first transparent electrode layer (5) close to the liquid crystal layer (3); a first alignment layer (4), located on a side of the planarization layer (6) close to the liquid crystal layer (3); a second transparent electrode layer (7), disposed on a side of the second substrate (2) close to the liquid crystal layer; a second alignment layer (8), disposed on a side of the second transparent electrode layer (7) close to the liquid crystal layer (3). The first alignment layer (4) is moved to a position where an lateral electric field is weaker, by forming the planarization layer (6) between the first transparent electrode layer (5) and the first alignment layer (4), which thus reduces a liquid crystal phase deviation and improves a refractive effect of the liquid crystal lens.

Abstract: The present disclosure provides a three-dimensional display device in which a pixel structure includes a plurality of sub-pixels arranged in rows and columns. In each column of sub-pixels, the sub-pixels are aligned. In each row of sub-pixels, each of the sub-pixels is staggered by half a sub-pixel with respect to an adjacent sub-pixel, and is different in color from the adjacent sub-pixel. The corresponding three-dimensional grating includes a plurality of strip-like grating structures periodically arranged in a horizontal direction, wherein the strip-like grating structures extend in the same direction that has a preset inclination angle with respect to the horizontal direction. Each strip-like grating structure corresponds to at least two sub-pixels in respective rows of sub-pixels which display different viewpoint images.
