More Information
Summary:An electron emission element (1) includes an electrode substrate (2) and a thin film electrode (3), and emits electrons from the thin film electrode (3) by voltage application across the electrode substrate (2) and the thin film electrode (3). An electron accelerating layer (4) containing at least insulating fine particles (5) is provided between the electrode substrate (2) and the thin film electrode (3). The electrode substrate (2) has a convexoconcave surface. The thin film electrode (3) has openings (6) above convex parts of the electrode substrate (2).
