Thin film transistor substrate and liquid crystal display including the same

A thin film transistor array panel includes: a substrate, a plurality of gate and data lines, a thin film transistor, a light blocking member, a color filter, and a pixel electrode. The substrate includes a display area having a plurality of pixels and a non-display area. The gate lines and data lines are formed on the substrate. The thin film transistor is connected to a respective gate line and data line of the plurality of gate and data lines. The light blocking member is formed on the non-display area, the gate line, the data line, and the thin film transistor. The color filter is formed on the light blocking member. The pixel electrode is formed on the color filter. The color filter covers the entire light blocking member of the non-display area.
