PURPOSE:To easily detect size difference between upper and lower barrier ribs in a bilayer structure barrier rib and improve manufacturing efficiency of gas discharging display panels. CONSTITUTION:Cathodes 3 are formed in parallel like stripes on the upper face of a back side substrate 2 made of an insulator and rows of white color first barrier ribs which are sandwitched between neighboring cathodes 3, are formed. Bluish violet color emitter layers 5 of mainly lanthanum hexaboride (LaB6) are formed between neighboring first barrier ribs 4 while coating the surface of the cathodes 3. Then, black color second barrier ribs 6 are formed and stuck to the upper faces of the first barrier ribs. The cathodes 3 formed on the back side substrate 2 and anodes 8 formed on a front substrate 7 made of a insulating material are arranged to face 8 and cross each other while keeping discharge spaces among them. |
