Image display apparatus

Abstract

An image display apparatus includes a plurality of pixels. Each of the pixels includes a light emitting element, a first thin film transistor, and a capacitor. The light emitting element has a light emitting region. The first thin film transistor is arranged outside the light emitting region in plan view. The capacitor is arranged inside the light emitting region in plan view.
