摘要： A gas discharge light emitting panel is provided that prevents deterioration in display properties of the panel, which accompanies changes in light-emitting properties of phosphors. It includes a front panel and a rear panel that are disposed to oppose each other, with a discharge space being interposed therebetween, and a phosphor layer that is disposed above a principal surface located on the discharge space side of the rear panel and that emits light by being irradiated with ultraviolet rays generated in the discharge space. The phosphor layer contains first and second phosphors in which the changes in at least one property selected from luminance and chromaticity, which accompany driving of the panel, occur in the opposite directions to each other.
