Abstract
An exemplary method for making a light blocking plate includes the steps of providing a flat plate-like light pervious member; forming a plurality of spaced ceramic power layers on the light pervious member; forming a light blocking layer over the light pervious member and side faces of the ceramic power layers; forming an electromagnetic shielding layer over the light blocking layer; removing top portions of the ceramic power layers with remaining portions of the ceramic power layers thus exposed; and removing the remaining portions of the ceramic power layers.
