PURPOSE: A sealing method of a field emission device is provided to reduce the damage of a device formed on a panel by performing a sealing process in a low temperature. CONSTITUTION: A frit glass(620) is applied to an upper substrate(600) by using a laser. The frit glass(620) is dried. A lower substrate(700) and the upper substrate(600) provided with the frit glass(620) are cemented and aligned. The frit glass(620) supporting the upper substrate(600) and the lower substrate(700) is sealed. A tube is provided on the upper substrate(600). The frit glass(620) is applied around the tube. A height of the frit glass(620) is higher or lower than that of a spacer with ±20-50 micro-meter.
