Abstract: A substrate for a display apparatus includes a substrate, and a capacitor on a first surface of the substrate. The capacitor includes a first electrode, a second electrode facing the first electrode, and a dielectric layer between the first electrode and the second electrode. Here, the substrate has a first hole penetrating through the substrate in an area corresponding to a part of the first electrode of the capacitor, and a first conductive material is in the first hole.
