Odorous pollutants emitted from the manufacturing process of TFT-LCD were investigated to prepare the odor control plan. Odor measurements in the workplace of clean room were also carried out. The odorous pollutants detected in the organic and acid gas emission duct were acetone, acetic acid, IPA, nbutylacetate, PGMEA, cyclohexane, which were chemicals used for LCD manufacturing. Especially, acetic acid was turned out to one of the major odor substances in the acid gas emission duct because of its low odor threshold value. No odorous pollutants were detected in the toxic gas emission duct. Some organic gases detected in the clean room were due to the leakage from chemical containers or LCD devices.
