This study analysis of environmental and economic value through Life Cycle Assessment(LCA) on recycling technologies for flat panel display devices. Environmental impacts were assessed for the five categories of impacts: global warming, resource depletion, acidification, eutrophication, and photochemical oxide production. When recycling 1kg of waste glass, global warming impact was 1.93E-02 kg CO₂-eq., resource depletion impact was 1.26E-04 kg Sb-eq., acidification impact was 3.29E-05 kg SO₂-eq., eutrophication impact was 6.13E-06 kg PO₄^3--eq., and the photochemical oxide production impact was 1.64E-05 kg C₂H₄-eq. When 1kg of recycled glass is produced, the result of analysis of environmental and economic value can be taken as 72 won. When producing 3,800 kg of recycled glass, it is possible to obtain 275,076 won of gain and 3,471,750 won in annual amount of waste glass.
