Title:
IMAGE FORMATION DEVICE AND ITS MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2005332698
Kind Code:
A
Abstract:
To provide a long-life image formation device hardly generating discharge during operation and capable of preventing generated ions from easily damaging a cold-cathode electron emission element, in an image formation device using the cold-cathode electron emission element.
This image formation device is composed by forming an evacuation space by sealing, through a joint material, a display panel 132 having a phosphor screen, and a back panel 131 having a cold-cathode electron emission element array facing to the display panel 132 for emitting an electron beam. In the evacuation space, a gas comprising at least one kind of He, Ne and Ar, or the gas and either Kr gas or Xe gas are/is introduced.
