Abstract
A display device is provided with a pair of a first electrode and a second electrode, at least one electrode of the first and second electrodes being transparent or translucent and a phosphor layer provided as being sandwiched between the first electrode and the second electrode, and at least one buffer layer provided as being sandwiched between the first or second electrode and the phosphor layer, and the phosphor layer has a plurality of pixel regions that are selectively allowed to emit light in a predetermined range thereof and non-pixel regions that divide at least one portion of the pixel regions, and wherein the buffer layer is sandwiched between the first or second electrode and the phosphor layer so that the size of an electric potential barrier between the first or second electrode and the phosphor layer via the buffer layer is made smaller than the size of a Schottky barrier between the first or second electrode and the phosphor layer that are directly made contact with each other without the buffer layer therebetween.
