PURPOSE: A frit sealing device using lasers is provided to improve the processing quality of frit by equalizing the energy distribution of a laser beam irradiated to the frit. CONSTITUTION: A laser head part (120) irradiates an inputted laser beam to frit. A control member (130) is arranged between the laser head part and the frit on the path of the irradiated laser beam. The control member includes a transmission part and a filter part. The transmission part faces the outside of a frit corner part and transmits all intensity of the laser beam irradiated to the frit. The filter part faces the inside of the frit corner part and transmits some of the intensity of the laser beam irradiated to the frit. |
