Abstract:
1. An organic EL device comprising: a substrate having an uneven surface and a front surface opposite the uneven surface; a first electrode layer formed on the front surface; an organic EL layer formed on the first electrode layer; a second electrode layer formed on the organic EL layer; a sealing member formed on the front surface of the substrate; and a sealing plate formed on the sealing member, the sealing plate being disposed over the second electrode layer and opposite from the substrate, wherein a first distribution characteristic of light emitted from the first and second electrode layers into the substrate has a first luminance in a direction of a first angle of 20 to 50 degrees measured with respect to an axis perpendicular to the substrate, the first luminance being relatively high as compared to other luminance of the light emitted into the substrate from the first and second electrode layers, and wherein a second distribution characteristic of light emitted from the first and second electrode layers into the sealing plate has a second luminance in a direction of a second angle of 20 to 50 degrees measured with respect to an axis perpendicular to the second electrode layer, the second luminance being relatively high as compared to other luminance of the light emitted into the sealing plate from the first and second electrode layers.
