An exemplary method for making a plurality of light blocking plates is provided. Firstly, a photoresist layer is formed on a substrate. Secondly, the photoresist layer is exposed using a gray scale photomask. Thirdly, the photoresist layer is developed to form a plurality of conical frustums on the substrate, and each of the conical frustums tapers in a direction away from the substrate. Fourthly, an opaque to-be-solidified film is formed on the substrate, and each of the conical frustums extends through the to-be-solidified film. Fifthly, the to-be-solidified film is solidified. Sixthly, the solidified film is separated from the substrate and the conical frustums, thus obtaining a light blocking plate module including a plurality of light blocking plates. Lastly, the light blocking plate module is cut into a plurality of individual light blocking plates.
