Abstract:
1. An electroluminescent device comprising: a substrate; a light-emitting region including a plurality of sub-pixels including switching elements, portions of an organic planarization layer for covering irregularities caused by the switching elements, reflective layers arranged on the organic planarization layer, protective layers extending over the respective reflective layers, the protective layers having insulative properties, light-transmissive first electrode layers which lie on the respective protective layers and which are electrically connected to the switching elements, portions of an organic light-emitting layer lying over the first electrode layers, and portions of a second electrode layer lying on the organic light-emitting layer; and a non-light-emitting region located outside the light-emitting region, wherein the light-emitting region and the non-light-emitting region are arranged on the substrate and the organic planarization layer extends from the light-emitting region to the non-light-emitting region and has an upper portion which is located in the non-light-emitting region and which is exposed from the protective layers.
