Organic EL display device

摘要

An organic EL display device includes a first substrate, a plurality of organic EL devices arranged on the first substrate, a second substrate arranged above the first substrate, and a filling layer arranged between the first substrate and the second substrate, and displays an image on the second-substrate side. The organic EL display device is characterized in that: the organic EL devices each have a light-emission layer, a reflection electrode formed below the light-emission layer and reflecting light from the light-emission layer upwards, and an upper electrode formed above the light-emission layer and having a light transmission property and reflectivity; a structure for resonating the light emitted by the light-emission layer is formed between the reflection electrode and the upper electrode; and the filling layer includes fine particles for diffusing light exiting from the upper electrode added therein.

1. An organic EL display device comprising:
a first substrate; a plurality of organic EL devices on the first substrate; a second substrate facing the first substrate; and a filling layer between the first substrate and the second substrate,wherein
an image is displayed on a second substrate side, each of the plurality of organic EL devices includes:
a light-emission layer;a reflection electrode below the light-emission layer to reflect light from the light-emission layer upwards;a bank configured to cover an edge of the reflection electrode; andan upper electrode above the light-emission layer and having a light transmission property and reflectivity, a structure which resonates the light emitted from the light-emission layer is formed between the reflection electrode and the upper electrode, the filling layer includes fine particles dispersed therein configured to uniformly diffuse the light in a visible wavelength region resonated by the structure and exiting from the upper electrode, the second substrate has a black matrix, the filling layer spreads under the black matrix and over the plurality of the organic EL devices, continuously, and the fine particles are dispersed in the filling layer both above the reflection electrode and between the black matrix and the bank.
