A transmission device for thin and brittleness substrate is disclosed, which comprises: a plurality of transportation rollers and a plurality of pinch rollers. Each transportation roller further comprises: a rigid spindle; and a plurality of elastic supporting wheels, mounted on the spindle. Each pinch roller comprises: a sleeve; a spindle, ensheathed in the sleeve; and a plurality of pressing wheels, mounted on the sleeve at positions corresponding to the supporting wheels. When the transportation rollers are driven to rotate, a substrate sandwiched between the supporting wheels and the pressing wheels will be push to move while subjecting to a friction originated from a sufficient holding force by the supporting wheels and the pressing wheels, and consequently, providing an improved buffering capability for deformation absorption that enables the transmission device to guide the thin substrate to move smoothly without causing buckling or scratching to the thin substrate.
