Abstract: A substrate transferring apparatus includes a first conveyer line assembly which transfers a substrate in a first direction, and includes a first base frame extending along the first direction, first and second pulleys respectively disposed at both end parts of the first base frame in the first direction, and a conveyer belt disposed on the first base frame, and driven by the first and second pulleys, and a first roller line assembly spaced apart from the first conveyer line assembly in a second direction which is substantially perpendicular to the first direction, and including a second base frame extending along the first direction, and a first roller part connected to the second base frame and including a plurality of rollers which contacts to the substrate.
