Abstract
A dielectric part 4 comprising a nitride layer 7 and an oxide layer 8, laid one upon the other, is formed on a data-recording layer 3. A light-transmitting layer 5 is boned with adhesive to the dielectric part 4. Since the dielectric part 4 is interposed between the data-recording layer 3 and the light-transmitting layer 5, the organic material of the data-recording layer 3 does not diffuse into the adhesive that bonds the light-emitting layer to the dielectric layer 4. Additionally, the data-recording layer 3 is not deteriorated due to the oxygen plasma generated during the process of forming the oxide layer 8, because the oxide layer 8 is provided on the nitride layer. Since the nitride layer 7 has a thickness of 10 nm or less, it does not influence optical enhancement effect.
