A gas discharge display unit having a partition wall structure which is useful for forming discharge cells suitable for the color image display with high precision is provided. A plurality of cathode electrodes are formed on a front panel. A plurality of anode buses, anode electrodes, auxiliary electrodes and resistors are formed on a back plate. A layer insulating film is formed on the back plate where the anode buses, the anode electrodes and the resistors are provided except for a display electrode portion. A display electrode is formed on the upper face of the anode electrode. Then, a three-layered insulating layer having differing quantities of a resin binder is formed on the layer insulating film. Unnecessary portions are removed by a sand blasting step to form partition walls comprised of partition layers. A phosphor is applied onto the layer insulating film in a discharge cell except for the display electrode portion. The front plate is joined to the back plate with the partition walls held therebetween in such a manner that the cathode ray tube is orthogonal to the anode bus.
