Abstract
An electron emission display includes: an electron emission substrate having at least one electron emission device formed thereon, an image forming substrate, and at least two spacers for supporting the electron emission substrate and the image forming substrate to be spaced apart from each other. Areas of the spacers per unit area are increased in at least one direction from a central region to a periphery region. The areas can be increased by, for example, increasing a cross-sectional area of each spacer or increasing the number of spacers. In another embodiment, heights of the spacers are decreased in at least one direction from the center region to the periphery region.
Claims19
An electron emission display comprising:
- an electron emission substrate including at least one electron emission device formed thereon;
- an image forming substrate;
- and
- at least two spacers for separating the electron emission substrate from the image forming substrate,
- wherein areas of the spacers per unit area are increased in at least a first direction from a central region to a periphery region of the electron emission display.
An electron emission display comprising:
- an electron emission substrate having at least one electron emission device formed thereon;
- an image forming substrate for forming an image based on collisions of electrons emitted from the electron emission device;
- and
- at least two spacers for separating the electron emission substrate from the image forming substrate,
- wherein cross-sectional areas of the spacers are increased in at least a first direction from a central region to a periphery region.
