PURPOSE: A method for evaluating a substrate is provided to discriminate a texturing region from a non-texturing region by using a simple formula. CONSTITUTION: A method for evaluating a substrate includes the following steps of: forming a plurality of protrusions by texturing the top surface of the substrate (S10); photographing the textured top surface (S20); measuring the highest height and the lowest height of the protrusions (S30); calculating reference height by using the highest height, the lowest height, and a Formula 1 (S40); and discriminating a texturing region having the protrusions higher than the reference height and a non-texturing region having the protrusions lower than the reference height (S50). Formula 1 : Hr=(Hmax-Hmin)×F+Hmin.
