  • Electroluminescent device, method for manufacturing electroluminescent device, and electronic apparatus
    Patent number: 8059067
    Abstract: An electroluminescent device includes 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, 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. The light-emitting region and the non-light-emitting region are arranged on the substrate.

  • Light emitting apparatus, method of manufacturing light emitting apparatus, and electronic apparatus
    Patent number: 7671376
    Abstract: A light emitting apparatus includes first and second unit devices, each including a reflecting layer, a semi-transmitting semi-reflecting layer, a first light emitting layer disposed between the light reflecting layer and the semi-reflecting layer, and a resonator structure. Each resonator structure includes a light transmitting pixel electrode disposed between the corresponding light reflecting layer and semi-reflecting layer. The pixel electrode of the first unit device has more electrode layers than the pixel electrode of the second unit device.
