Abstract
A mark substrate includes a base substrate, a light-blocking layer disposed on the base substrate, where an opening or a groove is defined in the light-blocking layer, and an infrared-transmitting member. At least a portion of the infrared-transmitting member is disposed in the opening or the groove of the light-blocking layer to define a mark having a two-dimensional shape and optically distinguished from an adjacent area.
