The present disclosure relates to a lens grate having a first substrate and a second substrate opposite to the first substrate, a first electrode layer on the first substrate, a resin layer on the first electrode layer, a second electrode layer on the second substrate, and a liquid crystal layer between the resin layer and the second electrode layer. One side of the resin layer facing toward the liquid crystal layer is configured with a plurality of concave spherical surfaces. By configuring the concave spherical surfaces, the thickness of the liquid crystal layer is gradually decreased along the direction from the center area to the rim area from regardless of the viewing directions, i.e., top-down, left-right, or slant, and thus the viewing angle is wide. With such design, the viewing angle of the 3D effect may be enlarged so as to enhance the 3D display performance.
