Abstract: A 3D printed display panel includes two opposing substrates and a black matrix formed on one of the substrates. The light proof areas of the black matrix include multiple first portions, multiple second portions and multiple third portions arranged to form a grid structure. The first portions and the third portions are alternately arranged in a direction of the scanning lines, the second portions and the third portions are alternately arranged in a direction of the data lines. Meshes of the grid structure are aperture zones of the black matrix. The aperture zones are in one-to-one correspondence with the pixel units. A vertical projections of the scanning lines and the data lines on the second substrate are located in the lightproof areas; where a minimum width of one first portion is X, a minimum width of one second portion is Y, and |X−Y|≤2 μm.
