Abstract
An inorganic electroluminescent device includes: patterned metal electrodes periodically disposed at pre-set intervals; and a phosphor layer positioned on the patterned metal electrodes, wherein as a first voltage and a second voltage are alternately applied to the patterned metal electrodes according to the order of their disposition, light emitted from the phosphor layer is discharged to the spaces between the patterned metal electrodes.
