Abstract: To solve the following problems of a light-emitting element that a large difference of refractive indices between a moisture barrier layer (a passivation film) like SiN formed at or on an opposing electrode and air remains as it used to be, and an outward light-taking-out efficiency is low; and peeling or cracking caused by stress of the moisture barrier layer is easily generated to lower the reliability and lifetime of the light-emitting element.SOLUTION: A light-emitting element according to the present invention is formed by laminating a pixel electrode, an electroluminescent layer, a transparent electrode, a passivation film, a stress relieving layer, and a low refractive-index layer. The stress relieving layer serves to prevent peeling of the passivation film. The low refractive-index layer serves to reduce reflectivity of light emitted from the electroluminescent layer when the light is incident 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.SELECTED DRAWING: Figure 1
