  • Publication number: 20080246387
    Abstract: The present invention aims to form an electron emission film containing an alkali metal compound or the like without causing alkali attack on the metal wiring. An FED display device comprises: an electron source including an electron emission film 13 on the surface thereof; and metal wirings 17, 18 and the like for supplying a signal or the like to the electron source. After forming on the surface of the metal wiring 18 an corrosion resistant film 21 comprising a reactive film or adsorption film with phosphorus, an alkali metal or the like is coated onto or added into the electron emission film 13. The addition of phosphorus is made fewer than the chemical equivalent of the alkali metal salt. Such configuration can improve the electron emission efficiency of the electron source without the metal wiring being corroded by alkali metal or the like.

  • Patent number: 6882402
    Abstract: Glass substrates interposed by unhardened thermosetting sealing material is surrounded by two sheets. The space between the sheets is placed in a roughly sealed state and decompressed to produce at least a partial vacuum between the sheets. The sheets serve to press the glass substrates against the sealing material by the pressure difference relative to the atmospheric pressure. One or more heaters spaced apart from the sheets heat the glass substrates and the sealing material, setting the sealing material.

  • Patent number: 6867841
    Abstract: The invention provides a high quality liquid crystal panel with low non-uniformity by enveloping a pair of glass substrates sandwiching an uncured thermosetting seal member with heat-resistant metal sheets, bringing the insides of the sheets into a substantially hermetically closed state to decompress the space around the substrates, pressing the glass substrates and the seal member by a pressure difference from the atmospheric pressure in a predetermined space created by the enveloping sheets, heating the sheets, the glass substrates and the seal member with a heater disposed at a position remote from the sheet and curing the seal member, and maintaining the gap between the pair of glass substrates to prevent non-uniformity of the gap between the pair of glass substrates constituting the liquid crystal panel.
