STRUCTURE AND FABRICATION METHOD OF DEVICE, SUCH AS LIGHT-EMITTING DEVICE OR ELECTRON-EMITTING DEVICE, HAVING GETTERING REGION

摘要

PROBLEM TO BE SOLVED: To provide a large getter region without causing marked increase in the overall side surface area of a structure, in a display device. SOLUTION: A light-emitting device is arranged by being provided with getter material 58 that can be readily distributed in a relatively uniform manner across the device's active light-emitting portion. The electron-emitting device is arranged similarly, by being provided with getter materials 112, 110/112, 128, 132 and 142 that can readily be distributed relatively uniformly across the active electron-emitting portion of the device. Techniques such as thermal spraying, angle-forming physical deposition, and maskless electrophoretic/dielectrophoretic deposition can be utilized for depositing the gettering material.
