    摘要: A surface emitting laser includes a lower multilayer mirror, an active layer, and an upper multilayer mirror stacked onto a substrate. A first current confinement layer having a first electrically conductive region and a first insulating region is formed above or below the active layer using a first trench structure. A second current confinement layer having a second electrically conductive region and a second insulating region is formed above or below the first current confinement layer using a second trench structure. The first and second trench structures extend from a top surface of the upper multilayer mirror towards the substrate such that the second trench structure surrounds the first trench structure. When the surface emitting laser is viewed in an in-plane direction of the substrate, a boundary between the first electrically conductive region and the first insulating region is disposed inside the second electrically conductive region.

    摘要: To prevent a point defect and a line defect in forming a light-emitting device, thereby improving the yield. A light-emitting element and a driver circuit of the light-emitting element, which are provided over different substrates, are electrically connected. That is, a light-emitting element and a driver circuit of the light-emitting element are formed over different substrates first, and then electrically connected. By providing a light-emitting element and a driver circuit of the light-emitting element over different substrates, the step of forming the light-emitting element and the step of forming the driver circuit of the light-emitting element can be performed separately. Therefore, degrees of freedom of each step can be increased, and the process can be flexibly changed. Further, steps (irregularities) on the surface for forming the light-emitting element can be reduced than in the conventional technique.

    摘要: The present invention provides a light-emitting element having less increase in driving voltage with the accumulation of light-emission time, and provides a light-emitting element having less increase in resistance value with the increase in film thickness. A light-emitting element includes a first layer, a second layer and a third layer between a first electrode and a second electrode. The first layer is provided to be closer to the first electrode than the second layer, and the third layer is provided to be closer to the second electrode than the second layer. The first layer is a layer including an aromatic amine compound and a substance showing an electron accepting property to the aromatic amine compound. The second layer includes a substance of which an electron transporting property is stronger than a hole transporting property, and a substance showing an electron donating property to the aforementioned substance.
