Image display apparatus, disassembly processing method therefor, and component recovery method

A flat panel display disassembly processing method for a flat panel display having a structure in which a face plate and a rear plate that are mainly containing glass are airtightly joined via a frame with frit glass, comprising;

• the step of dissolving the frit glass with nitric acid, wherein
• the step of dissolving the frit glass with nitric acid comprises dipping into nitric acid only a joint portion between the rear plate and the frame to reuse the face plate equipped with the frame.

A rear plate recycling method for an image display apparatus constituted by at least a rear plate having a plurality of electron-emitting elements each formed from a pair of element electrodes and a conductive film, a face plate having an image forming member on which an image is formed by electrons emitted by the electron-emitting element, and a support frame which connects the rear plate and the face plate and maintains an internal pressure, the rear plate being recovered and reused in scraping the image display apparatus constituted by welding the face plate, the rear plate, and the support frame with frit glass, comprising:

• the step of dipping the welded portion in a nitric acid solution to dissolve the frit glass, thereby recovering the face plate;
• and
• the step of forming a conductive film on the recovered rear plate by an ink-jet method.

A scrapped flat panel display disassembly processing method for a flat panel display having a structure in which a face plate and a rear plate mainly containing glass are airtightly joined via a frame with lead-containing frit glass, comprising the steps of:

• separating and extracting a portion including the face plate and a portion including the rear plate from the flat panel display to be scrapped;
• and
• separately collecting pluralities of extracted portions including face plates and extracted portions including rear plates, separately immersing the collected portions including the face plate and the collected portions including the rear plate into baths containing processing liquid.
