METAL INCLUDED SOLUTION FOR ELECTRON EMITTING UNIT, FORMING MANUFACTURE OF ELECTRON EMITTING ELEMENT USING THIS SOLUTION, ELECTRON SOURCE, DISPLAY PANEL AND IMAGE FORMING DEVICE

Japanese Patent JP3227090

B2

PROBLEM TO BE SOLVED: To simplify the conductive thin film forming process, to homogenize electron emitting element, and to reduce the unevenness of luminance of a device by using the liquid including the organic metal complex, which includes amino alcohol in a molecule.
SOLUTION: Isopropyl alcohol is added to paradium acetate, and agitated, and while amino-methyl-propanediol is added, and they are agitated, and after a reaction is generated, this reaction mixture liquid is filtered, and the pressure of the filtered liquid is reduced for distillation. Acetone is added to the residue, and crystallized for filtering, and acetone is added to this crystal, and agitated, and filtered again. This operation is repeated, and after washing the crystal with acetone, the crystal is dried in vacuum so as to obtain paradium acetate. As a result, in a process for manufacturing electron emitting element, deposition of crystal of the metal compound is eliminated, and homogenized element can be manufactured.

JP3332576	PROBLEM TO BE SOLVED: To provide a multi-cold cathode electron source, its driving method, and an image display device.
JPH0821315	INDUSTRIAL APPLICABILITY: A discharge display tube and a composition for forming a cathode thereof.
JPH09230819	IMAGE FORMING DEVICE, METHOD AND CIRCUIT FOR DRIVING IT
