    • An active matrix display apparatus includes a transistor, a storage capacitor, and a light-emitting element formed on a substrate. The transistor includes a source electrode, a drain electrode, and a gate electrode. The storage capacitor has a multilayered structure of a first electrode, a dielectric layer, and a second electrode stacked in this order on the substrate, and the light-emitting element has a multilayered structure of a third electrode, a light-emitting layer, and a fourth electrode stacked in this order on the substrate. The first electrode is electrically connected to the gate electrode of the transistor, and at least a part of the storage capacitor is disposed between the substrate and the light-emitting element. All of the substrate, the first electrode, the second electrode, and the third electrode are formed from a material transmitting a visible light emitted by the light-emitting element. Viewing from a top of the substrate, a region for storing charges in the storage capacitor includes or is equal to a light-emitting region of the light-emitting element.
