A gas discharge display panel in which the wall charge holding ability is maintained even though the manufacturing cost is relatively low, the discharge delay is controlled within a region best suitable for image display, and favorable display performance can be exhibited by lowering the discharge start voltage is provided. A PDP in which the secondary electron emission coefficient gamma is improved more than conventional, the drive margin is widened by lowering the discharge start voltage, and thus the display quality and the reliability are enhanced and a gas discharge display panel manufacturing method in which the exhaust time at a sealing exhaust step is shortened to reduce the manufacturing cost and the driver circuit cost is reduced are provided. A protective layer contains MgO as the main component, Si in a range of the added amount from 20 mass ppm to 5,000 mass ppm, and H in a range of the amount of added amount from 300 mass ppm to 10,000 mass ppm. ® KIPO & WIPO 2007
