METHOD OF FABRICATING BOTTOM CHASSIS, BOTTOM CHASSIS FABRICATED BY THE METHOD OF FABRICATING THE SAME, METHOD OF FABRICATING LIQUID CRYSTAL DISPLAY, AND LIQUID CRYSTAL DISPLAY FABRICATED BY THE METHOD OF FABRICATING THE SAME

摘要

A method of fabricating a bottom chassis is provided. The method of fabricating the bottom chassis includes, for example, forming a bottom chassis using a steel plate having a thickness in the range of 0.5 mm to 0.9 mm, the steel plate having a stack structure including an inner layer containing 0.001 to 0.1 weight percent (wt. %) carbon (C), 0.002 to 0.05 wt. % silicon (Si), 0.28 to 2.0 wt. % manganese (Mn), balance iron (Fe), and other impurities, an electro-galvanized layer formed on the inner layer, and a polymer chromium (Cr)-free contamination resistant layer formed on the electro-galvanized layer, and performing a burring process and a tapping process on the bottom chassis to form a burring part to receive a bolt for an engagement.
