PROBLEM TO BE SOLVED: To provide a liquid drop discharging method for a liquid drop discharging device improved in the uniformity of the volume of a liquid discharged to respective discharge areas by compensating the temperature variation generated by heat radiation caused by discharge of the liquid, and to provide a liquid drop discharging device. SOLUTION: A substrate heater H is installed which heats up a mother counter board 15 facing to the respective discharge areas S of the mother counter board 15. The substrate heater H is provided with an X-axis heater HX facing the discharge area S of each line and a Y-axis heater HY facing the discharge area S of each row. The Y-axis heater is set up at such a temperature as to compensate the temperature drop of a discharge head 31 due to the discharge of liquid crystal. The X-axis heater XH is set up at a higher control temperature in the vicinity of the outer peripheral edge than in the vicinity of a center position so as to compensate the heat variation of the discharge head 31 due to heat exchange with the mother counter board 15.
