Beschreibung
Zusammenfassung:	The utility model discloses an optical plate. The optical plate consists of a plurality of optical plate units which are spliced. Each optical plate unit is hexahedral. Two of four continuous lateral surfaces of each optical plate unit have a tenon structure respectively, and the other two lateral surfaces have a mortise structure respectively. The optical plate units are spliced by embedding the tenon structures into the mortise structures. The utility model also discloses a backlight source and a liquid crystal display respectively comprising the optical plate. By the optical plate, the backlight source and the liquid crystal display, the structure of a backlight source module can be simplified, and light guide plates forming the backlight source can be simply spliced.
