PROBLEM TO BE SOLVED: To provide an inexpensive surface treated steel sheet for liquid crystal front frame having excellent mechanical properties and also to provide a liquid crystal front frame using it. SOLUTION: The surface treated steel sheet for liquid crystal front frame is constituted in such a way that a surface treated layer is formed on the surface of a steel sheet having a composition consisting of, by weight, 0.03 to 0.20% C,≤0.5% Si, 0.5 to 3.0% Mn,≤0.1% P,≤0.06% S,≤0.1% Al, 0.0010 to 0.0160% N and the balance Fe with inevitable impurities.
