Abstract

A top-emission type organic EL panel has a substrate carrying thin film transistors formed thereon, a plurality of organic EL devices formed on the substrate, each of the organic EL devices including a reflecting electrode, organic compound layers and a transparent electrode arranged in this order from the substrate side, a device separation layer formed in a space separating adjacently located organic EL devices, a protective layer covering the organic EL devices and the device separation layer and a light-shielding layer formed on the protective layer in a display region other than light emitting sections of the organic EL devices so as to be held in contact with the protective layer and cover at least part of lateral surfaces of the device separation layer.

Claims (8)

1. An organic EL panel comprising:

a substrate;

a plurality of organic EL devices arranged on the substrate;

a device separation layer arranged in a space separating adjacently located organic EL devices and having an inclined lateral surface;

a protective layer covering the organic EL devices and the device separation layer; and

a light-shielding layer arranged on the protective layer in a display region other than light emitting sections of the organic EL devices and covering the inclined lateral surface of the device separation layer.

2. The organic EL panel according to claim 1 , further comprising a transistor arranged on the substrate, wherein the light-shielding layer is made of an electro-conductive material and is provided to have a distance from the transistor of not less than 1 μm and not more than 7 μm.

3. The organic EL panel according to claim 1 , wherein the light-shielding layer covers a part of the transistor.
