<p><P>PROBLEM TO BE SOLVED: To provide the field emission type light-emitting device which can make a brightness of light-emitting face uniform. <P>SOLUTION: The light-emitting device 10 comprises the field emission type electron source 4 consisting of a cathode electrode 42 and a carbon nanotube (CNT) layer 41, an anode electrode 62, a phosphor membrane 61, a gate electrode 5, and a closed insulating substrate 2 that extends from the field emission type electron source 4 to the direction of the phosphor membrane 61. Between the gate electrode 5 and one end part of the phosphor membrane side of the insulating substrate 2, an electric field control electrode 3 is installed, and at the same level of the end part of the interior of the closed insulating substrate 2, an electrostatic charged body 7 is arranged and installed that is electrostatically charged by collision of electrons released by the field emission type electron source 4 to costitute a cell 1. Numerous cells 1 are assembled to constitute the light-emitting device 10. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
