Abstract: PURPOSE: A welding mask using polymer dispersed liquid crystal is provided to drastically enhance work efficiency and to distribute at low cost. CONSTITUTION: A welding mask using polymer dispersed liquid crystal comprises a mask(100) protecting facial area in the welding, a supporter(300) in which a user can wear mask, safety glasses(200) confirming the welding state by being installed at the upper end of the mask, and a power supply unit which applies voltage to a polymers distribution type liquid crystalline film. The safety glasses comprise transparent sight glasses, and a polymer distribution type liquid crystalline film adhered to the transparent sight glasses.
