Abstract:
    A liquid discharge device has a tank for containing liquid crystals, a substrate stage on which a mother substrate is placed, and a discharge head placed so as to face the substrate stage. The discharge head and the substrate stage are movable relative to each other. The discharge head has a nozzle plate where a nozzle is formed. The discharge head pressurizes the liquid crystal fed from the tank and discharges it toward the mother substrate. A heater for the discharge head is provided around the discharge head, and the heater controls the temperature of liquid crystals. The heater for the discharge head has an extended section extending more to the substrate stage side than the nozzle plate, and the extended section surrounds the nozzle plate. Therefore, the viscosity of liquid crystals can be maintained sufficiently low near the nozzle.
