An organic EL display device including first electrodes and second electrodes to which a voltage is applied; conductive color changing layers capable of being electrically connected to the first electrodes; and an organic luminescent medium placed between the second electrodes and the color changing layers. When a voltage is applied between the first and second electrodes, an electric field is generated between the second electrodes and the color changing layers in contact with the first electrodes. As a result, the organic luminescent medium emits light therebetween. Because no or little light interference exists between the first and second electrodes, chromaticity does not change even if a viewing angle is changed. Because the color changing layers can be placed in contact with or very close to the organic luminescent medium, a color mixture due to changes in viewing angle hardly occurs.
