Claim:
1. A parallax barrier, comprising: a first substrate; a second substrate, cell-assembled with the first substrate; a peripheral cavity wall, disposed on a periphery of the first substrate and the second substrate to form a closed cavity; a hydrophilic fluid and a hydrophobic fluid, filled in the closed cavity, wherein the hydrophilic fluid is a transparent material and the hydrophobic fluid is an opaque material; a first electrode, disposed at a side of the first substrate facing the second substrate; a second electrode, disposed at a side of the second substrate facing the first substrate; a hydrophobic-hydrophilic switching layer, disposed at a side of the second electrode facing the first substrate; and a plurality of barrier walls, disposed at a side of the hydrophobic-hydrophilic switching layer facing the first substrate parallel to each other and spaced apart from each other along a direction parallel to a plane in which the second substrate is located, wherein at least a part of each of the plurality of barrier walls is transparent, and when not being powered on, a thickness of the hydrophobic fluid is not larger than a height of each of the barrier walls, and when being powered on, a highest place of each of accumulation regions of the hydrophobic fluid is not higher than a highest place of the corresponding barrier wall, wherein each of the plurality of barrier walls comprises a transparent barrier strip, and widths of transparent barrier strips become narrower in a direction from a middle position of the second substrate to any edge thereof.
