LIGHT EMITTING DEVICE WITH GETTER REGION OR STRUCTURAL BODY OF DEVICE LIKE ELECTRON DISCHARGING DEVICE, AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a display device in which a large getter region is obtained without increasing remarkably a total lateral area of a structural body. SOLUTION: The light emitting device is provided accompanying a getter substance (58) which is distributed easily by a relatively uniform method while crossing an active light emitting portion of the device. The electron discharging device is similarly provided accompanying a getter substance (112, 110/112, 128, 132, 142) which is distributed easily while crossing an active electron discharging portion of the device. Such technologies as thermal spray, angled physical deposition, maskless electrophoresis deposition/dielectric electrophoresis deposition are used for depositing the getter substance.
