Abstract
A transparent plate includes: a grating structure layer, including a first surface and a second surface opposite to each other, where a grating structure is disposed on the first surface; and a micro-texture layer, disposed on the second surface, where a surface of the micro-texture layer away from the second surface includes a plurality of micro-texture stripes, and light interferes between the grating structure and the micro-texture layer and forms moire stripes.
