PURPOSE: An image displaying apparatus is provided to suppress the discharge between the anode and any other part and to improve a reliability. CONSTITUTION: The rear plate(1005), the side wall(1006) and the face plate(1007) constitute a hermetic package for maintaining the inside of the image displaying panel in a vacuum. The rear plate(1005) is provided with a substrate(1001), and a plurality of surface conduction electron-emitting devices(1002) are formed in a matrix on the substrate(1001). On the face plate(1007) are formed a phosphor membrane(1008) and a metal-backing(1009). Moreover, spacers(1012) are formed between the rear plate(1005) and the face plate(1007) in the Y-direction at a predetermined interval. Incidentally, a detailed description will be given later to the positional relation between the structure of the principal part such as an anode(1014), a potential regulating electrode(1015) and the like and the spacers(1012).
