PURPOSE:To improve the display quality and yield by providing a groove between a grid-shaped partition wall section made of a thick film and a peripheral edge section formed on the substrate inner face of a face discharge type gas discharge panel so that the peripheral edge section softened by the processing heat does not infiltrate into the partition wall section. CONSTITUTION:A grid-shaped partition wall section 3 made of low-melting point glass and a wide edge section 5 are formed by printing across a groove 4 on the inner face of an upper substrate 2, a phosphor is coated on the partition wall section 3, and opening sections 6 arranged in a matrix shape are provided. On the other hand, maintaining electrodes X, Y are covered with a dielectric layer 8 on a lower substrate, and a selecting electrode A insulated from the maintaining electrodes X, Y and crossing them is formed. A spacer 10 and a seal 11 keep a space introducing the discharge gas between the upper and lower substrates 1, 2. If a panel with such constitution is used, the edge section 5 does not infiltrate into the partition wall section 3 by the existence of the groove 4 in the baking process, thereby the area of the opening sections 6, i.e., the luminous area, is not reduced, and the display quality and yield are improved.
