Abstract

Disclosed are a non-evaporation type getter excellent in gettering effect, capable of maintaining the inside of a gas-tight container in a display apparatus, particularly a flat panel display apparatus or the like, in a high vacuum condition, easy to mount and less liable to contaminate the inside of the gas-tight container, a display apparatus including the getter, and methods of manufacturing the same. The non-evaporation type getter (20) includes a molded body including at least one element selected from the group consisting of Ti, Zr, Al, V, and Fe as a principal constituent thereof, the molded body formed by powder injection molding. The molded body is composed of a porous body having a porosity of 10 to 30%.

Description

technical field [0001] The present invention relates to a non-evaporable getter, a display device and a manufacturing method thereof. Background technique [0002] Flat panel display devices such as field emission displays (hereinafter abbreviated as FEDs) have been proposed in recent years, in which phosphors are irradiated with electron beams emitted from electron emission sources such as field emission devices to cause fluorescence The body emits light to form an image. [0003] In the FED, a substrate provided with electron emission sources arranged in a matrix form and a substrate provided with phosphors are disposed opposite to each other with a slight gap therebetween, and the peripheries of these substrates are sealed to form an airtight container, the inside of which is A high vacuum or an ultra-high vacuum is maintained, and the phosphor is irradiated with an electron beam emitted from an electron emission source to cause the phosphor to emit light, thereby displa...
