A method of producing an electron-emitting device includes the steps of forming a pair of electrodes and an electrically-conductive thin film on a substrate in such a manner that the pair of electrodes are in contact with the electrically-conductive thin film and forming an electron emission region using the electrically-conductive thin film, wherein the method is characterized in that a solution containing a metal element is supplied in a droplet form onto the substrate thereby forming the electrically-conductive thin film.

A method for manufacturing electron emitting devices each having electrodes formed on a substrate and an electroconductive thin film connected between a pair of electrodes and having an electron emitting region is provided which can manufacture electron emitting devices having an excellent uniformity of electron emitting characteristics by improving the formation of liquid droplets to be dispensed to the substrate. In the manufacturing method, the substrate formed with the electrodes is subjected to a hydrophobic process using a silane coupling agent which contains two or more acetoxy groups in a molecule, and thereafter liquid droplets containing material for forming the electroconductive thin film are dispensed to the substrate. An image of excellent uniformity can be displayed by adopting electron emitting devices manufactured in the above manner to an image display apparatus.
A method and apparatus for depositing a soluble material, such as an organic polymer, onto a substrate uses an inkjet print head. The substrate is viewed from the underside by a CCD microscope during the deposition of an organic polymer droplet onto a well provided in a bank structure. As the organic polymer droplets are viewed when in wet condition they are more clearly visible and any offset or deviation detected between the deposited droplet and the well can be used to reposition a platen supporting the substrate. The substrate is viewed with light having a wavelength to which the substrate is transparent and, preferably, which does not include a wavelength component within the absorption region of the polymer.
The present invention provides a method for fabricating an envelope, which has a high freedom of process, is economical and allows an easy process management. The method aims to fabricate an envelope formed by sealing first and members, the envelope having a vacuum space therein, and basically comprises a step of baking the first and second members in vacuum in a first chamber, a carrying step of carrying the first and second members subjected to baking from the first chamber to a second chamber in an atmosphere in which an air having a predetermined dew point is maintained at a temperature exceeding such dew point, and a sealing step of sealing the first and second members in vacuum in the second chamber thereby forming the envelope. The method allows to economically provide an image display device and an image display apparatus of satisfactory display quality.
