Abstract:
An organic EL display is constituted by providing a stress-relieving layer made of a material having a higher elastisity and a lower refractive index than an adhesive layer at edges of color-converting filters that are constituted from color filter layers alone, or color filter layers and color-converting layers, and are formed on a transparent supporting substrate. As a result, stress arising when bonding the color-converting filters and the organic light-emitting device together, or when there are changes in the environment in which the display is placed is absorbed by the stress-relieving layer, and hence the light-emitting device is not damaged, and moreover reflection at walls of the stress-relieving layer is promoted, and hence there is a reduction in the component of the light emitted by the light-emitting device that escapes sideways. An organic EL display having high reliability and high efficiency is thus provided.
