    摘要： The present application relates to a sheet comprising, in a single layer, a first light control part capable of providing light always totally reflected only in a specific interlayer laminate structure among sheet constructions; and a second light control part capable of providing light whose total reflection is determined according to a fingerprint pattern in contact with the surface layer of the sheet by changing a part of the light provided from the first light control part and totally reflected in the specific interlayer laminate structure at a predetermined angle and emitting it to reach the surface layer of the sheet without being totally reflected in the specific interlayer laminate structure, and a device thereof. The sheet has excellent user identification or authentication capability through a fingerprint and can be applied to a large area display device to recognize a plurality of fingerprint patterns without being influenced by each other.
