Abstract: A display device including a pixel circuit, an insulation layer covering the pixel circuit, an etching prevention layer disposed on the insulation layer, a first guide layer, a second guide layer, a first electrode, a second electrode, and a light emitting element. The first guide layer and the second guide layer may be disposed on the etching prevention layer and spaced apart from each other. The first electrode may be disposed on the first guide layer and electrically connected to the pixel circuit. The second electrode may be disposed on the first guide layer and insulated from the first electrode. The light emitting element may be in contact with the top surface of the etching prevention layer, disposed between the first guide layer and the second guide layer on a plane, and electrically connected to the first electrode and the second electrode.

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.
