摘要： PURPOSE:To provide an inexpensive fluorescent character display device free from the occurrence of a crack on a semiconductor chip mounted on a glass substrate, or the glass substrate itself. CONSTITUTION:Regarding a fluorescent character display device having a structure where a display section and a semiconductor chip 6 for driving the display section are mounted on the same glass substrate 1 in an identical vacuum envelope, the first and second thin metal sheets 14a and 14b are laid between the chip 6 and the substrate 1. Both of the sheets 14a and 14b are formed out of a material having a thermal expansion coefficient nearly equal to the thermal expansion coefficients of the chip 6 and substrate 1. The chip 6 is bonded to the sheet 14a using an inorganic adhesive 13a, and the other sheet 14b is pasted to the sheet 14a at the opposite side of the bonded chip 6. The assembled body of the first and second thin meal sheets 14a and 14b is fastened to the upper surface of the glass substrate 1 by bonding the sheet 14b thereto using another inorganic adhesive 13b.

摘要： PROBLEM TO BE SOLVED: To provide uniform brightness when turning on, and to prevent leakage of light when turned off, even if display patterns have large areas and closed shapes. SOLUTION: In this fluorescent display tube, an insulating layer 2 is formed on an insulating substrate 1 opposite to a negative electrode, and positive electrode conducting layers 4 are formed on the insulating layer 2, then fluorescent layers 5 having shapes corresponding to display patterns are formed on the positive electrode conducting layers 4, thereafter ribs 6 made of an insulating material and higher than the fluorescent layers 5 are formed around the fluorescent layers 5, thus main grid conducting layers 7 are formed on the tops of the ribs 6. If the display patterns are closed annular shapes, ribs 6c made of the insulating material are formed inside the annular fluorescent layers 5. Inside grid conducting layers 7c are formed on the tops of the ribs 6c, then the main grid conducting layers 7 are electrically connected with the inside grid conducting layers 7c by narrow wiring conductors 7d crossing the fluorescent layers 5.

摘要： PURPOSE: To set an interval between light emission patterns small without generating light emission irregularity in a fluorescent character display tube having a grid electrode at a peak part of a rib wall surrounding a phosphor layer. CONSTITUTION: To an auxiliary grid electrode 24 provided at a peak part of an auxiliary rib wall 46 provided on the outer circumferential side of a rib wall 44, a constant voltage is applied constantly. For the auxiliary grid electrode 24 provided between adjacent grid electrodes 22, when an acceleration voltage is applied to either grid electrode 22, therefore, it acts to cancel a negative field generated by the other grid electrode 22 to which a erasing voltage is applied. It thus becomes the auxiliary grid electrode 24 which is common for the adjacent grid electrodes 22, 22, thereby the number of the auxiliary grid electrodes 24 to be provided between the grid electrodes 22, 22 can be the minimum required for cancelling the negative field generated by the grid electrodes 22 to which the deleting voltage is applied.
