Document Type and Number:
Japanese Patent JP3747154
Kind Code:
B2
Abstract:
An image forming apparatus comprises a first substrate (1), a second substrate (11), a support frame (4) arranged between the first (1) and second (11) substrates, and surrounding a space between the first (1) and second (11) substrates, a plurality of electron emitting devices arranged on the first substrate (1) facing the space, and an image forming member (12) arranged on the second substrate (1). A spacer (101) is disposed in the space between the first (1) and second (11) substrates, and a conductive film (5) is arranged on the second substrate (11) to surround the image forming member (12). The conductive film (5) is supplied with a potential lower than that applied to the image forming member (12), and the spacer (101) has a length greater than that of the image forming member (12). Each longitudinal end of the spacer (101) is arranged between the inner periphery of the support frame (4) and a respective plane through which a corresponding end of the conductive film (5) extends perpendicularly to a principal surface of the second substrate (11).
