    摘要： There has been a problem that difference in refractive index between an opposite substrate or a moisture barrier layer (passivation film) such as SiN provided thereover, and air is maintained large, and light extraction efficiency is low. Further, there has been a problem that peeling or cracking due to the moisture barrier layer is easily generated, which leads to deteriorate the reliability and lifetime of a light-emitting element. According to the present invention, a light-emitting element comprises a pixel electrode, an electroluminescent layer, a transparent electrode, a passivation film, a stress relieving layer, and a low refractive index layer, all of which are stacked sequentially. The stress relieving layer serves to prevent peeling of the passivation film. The low refractive index layer serves to reduce reflectivity of light generated in the electroluminescent layer in emitting to air. Therefore, a light-emitting element with high reliability and long lifetime and a display device using the light-emitting element can be provided.

    摘要： A novel phosphor material which can be manufactured without utilizing a fault formation process which is difficult to be controlled. The phosphor material has a eutectic structure formed of a base material that is a semiconductor formed of a Group 2 element and a Group 6 element, a semiconductor formed of a Group 3 element and a Group 5 element, or a ternary phosphor formed of an alkaline earth metal, a Group 3 element, and a Group 6 element, and a solid solution material including a transition metal. The phosphor material is suited for an EL element because of less variation of characteristic since defect formation process in which stress is applied externally to form a defect inside of a phosphor material is not needed.
