FORMING METHOD OF NON-EVAPORATION TYPE GETTER, IMAGE FORMING DEVICE USING SAME NON-EVAPORATION TYPE GETTER, AND ITS MANUFACTURE

摘要

PROBLEM TO BE SOLVED: To provide an image forming device undergoing less change in brightness with lapse of time (less deterioration in brightness with lapse of time) and provide an image forming device undergoing less variation in brightness in an image forming region with lapse of time, by disposing a getter film of large capacity and of a large surface area in a display region of the image forming device by employing a structure suitable for mass production and a method of low-cost manufacturing. SOLUTION: As a mask 5 for thermal spraying used to screen parts other than a formed part of a getter 11 formed by a thermal spraying method from a thermal spraying source, a mask 5 provided with a separation film 7 is used to facilitate the recycling of the mask 5 by removing a getter material 10 deposited on the mask 5. This method has a process for forming the getter 11 by using the mask 5 and a process for collecting the getter material 10 deposited on a surface of the mask 5.
