摘要： PROBLEM TO BE SOLVED: To provide a cold cathode material which causes a high-efficient/ long-life cold cathode fluorescent tube that functions as a cold cathode using a low voltage in the ranges of currents and current densities where this has not been achieved with W, Ni material or stoichiometry conductive oxide material, with this characteristics long endured. SOLUTION: The cold cathode material a conductive oxide material containing more than one element out of lanthanoide, alkali-earth element, yttrium, and more than one element out of transit metal element. This percentage of composition contains the oxygen deficiency conductive oxide material which is deflected toward a deoxidized direction from stoichiometly due to the deficiency of oxygen mainly. The cold cathode fluorescent tube uses such a cold cathode material for a cold cathode 3.

摘要： PURPOSE:To allow the drive at a low voltage and improve the quality of display by mixing, to an element represented by a specified chemical formula, a material having a high resistivity of a chemical formula similar to that in a determined quantity. CONSTITUTION:A perovskite conductive oxide represented by a chemical formula (A11-x, A2yBO3) is used as a bed electrode 2Ag, and a material having a chemical formula of a composite similar to that and a resistivity higher than that is mixed in 5-50% by mole ratio to form a cathode 3. In the formula, A1 and A2 each represent any one of elements La, Ca, Sr, and Ba, and B represents any one of elements Cr, Mn, Fe, Co, and Ni. X and Y are actual numbers of 0-1. The oxide conductor paste is screen-printed, dried in the atmosphere, and further baked in the atmosphere. A discharge space formed by laminating a back glass 1 having the cathode 3 formed thereon and a front glass 6 having an anode 4 and a bulkhead 5 is highly vacuumed. Then, discharge is uniformed and the drive at a low voltage can be performed, and a satisfactory display product can be provided.

摘要： PROBLEM TO BE SOLVED: To provide an internal electrode structure which prevents flickering of dielectric barrier discharge of a type that a main discharge is generated between an internal electrode and an external electrode.
SOLUTION: A light source device has a first electrode located at the end inside a hermetic vessel and a second electrode located outside the hermetic vessel to excite the hermetic vessel in which a discharge medium is sealed. A condition that a tip shape of the first electrode is a curved surface can control discharge motion on the first electrode, and prevents flickering.
