A thin film transistor type liquid crystal display element capable of being reduced in weight and slim is provided. A panel unit includes a liquid crystal filled between a thin film transistor substrate and a color filter substrate, a light source, and an optical plate, and includes a backlight unit that irradiates light to the panel unit. The bottom chassis 130 that houses the light unit is carbon (C): 0.001 to 0.1 wt%, silicon (Si): 0.002 to 0.05 wt%, manganese (Mn): 0.28 to 2 An inner layer containing 0.0 wt% and the balance iron, an electrogalvanized layer formed on the outer surface, and a polymer chromium-free antifouling layer formed on the surface of the electrogalvanized layer, It has a thickness of ˜0.9 mm, and is fixed to the front surface of the backlight unit with the top chassis 140 in a form surrounding the front edge and side surface of the panel unit.
