Abstract: A thin film transistor substrate having a structure in which a thin film transistor array is formed on color filters. In the substrate, a thin film transistor is formed on the color filters. A smoothing layer compensates for step coverage between the color filters and is provided with a recess in which a gate electrode of the thin film transistor is to be formed. Accordingly, step coverage in the gate electrode is eliminated, so that it becomes possible to manufacture a large-dimension panel without a limitation to the thickness and profile of the gate electrode.
