A manufacturing method of an active matrix substrate which can prevent the complexity of manufacturing processes, widens the range of material choice and allows high manufacturing yield, and a manufacturing method of a liquid crystal display using such active matrix substrate. The coolant area forms a line system with the line parts thereof, that are laterally connected thereto, and a condenser area of a cold unit, in which a coolant circulates in the line system as result of a thermosiphon effect. The entire draw jet assembly is moveable vertically for filament optimization. The housing and the nozzle cooperating to define a material feed opening such that the material feed opening intersects the gas conduit proximate the outlet end of the nozzle. The invention also relates to a bit rate adaptation model which is used for signaling between the transmitter and the receiver.
