Abstract: A substrate on which a plurality of pixel electrodes are disposed is prepared. An organic electroluminescent film 22 is formed with the inclusion of a common layer that continuously covers the plural pixel electrodes. A common electrode is formed on the organic electroluminescent film. The common layer is irradiated with an energy ray above areas between the respective adjacent pixel electrodes with the avoidance of irradiation above the plural pixel electrodes. An electric conductivity of the common layer is reduced above the areas between the respective adjacent pixel electrodes, by irradiation of the energy ray. With this configuration, a current leakage can be prevented between the adjacent pixels.
Abstract translation: 制备其上设置有多个像素电极的基板。 形成有机电致发光膜22，其包括连续地覆盖多个像素电极的公共层。 在有机电致发光膜上形成公共电极。 在各个相邻的像素电极之间的区域上方的能量射线照射公共层，避免了在多个像素电极之上的照射。 通过能量射线的照射，共同层的电导率降低到各个相邻像素电极之间的面积之上。 利用这种配置，可以防止相邻像素之间的电流泄漏。
