Abstract: A tray for transferring a panel is disclosed. The tray includes a tray mold frame including acrylonitrile-butadiene-styrene (“ABS”) resin, a receiving member, a supporting member and a slot member. The tray mold frame includes four extrusion bars and four molding members. The molding members combine with the extrusion bars. Each of the molding members include a first protruding part on a side surface. The receiving member is disposed inside of the tray mold frame. The supporting member is disposed on a lower surface of the receiving member. The supporting member combines with the extrusion bars configured to support the receiving member. The slot member includes a first groove combining with the first protruding part. The slot member is disposed on the receiving member. Thus, when the panel is transferred by the tray, a fault of the panel during transferring may decrease.
