Abstract
In a flat type image forming apparatus formed by electron emitting devices, the invention is to provide a light emitting substrate, capable of relaxing influence of an abnormal discharge on the electron emitting devices. On a glass substrate, a resistor memberextending in X- and Y-direction, and a black memberextending in X- and Y-directions are formed. Phosphorsare positioned in apertures of the black member, and are covered by metal backsdivided in X- and Y-directions. The metal backsand the resistor memberare electrically connected through the black member, and the resistance between the metal backsis defined by the resistor memberin the Y-direction in which the adjacent metal backshave a wider gap than in the X-direction.
