The invention mitigates a drop of a protective layer and reduces disconnection of an electrode. A shading layer, a partition layer to partition a color filter layer, formed on the shading layer, and a protective layer to seal the shading layer, the partition layer and the color filter layer, are arranged on a substrate. At least a part of the partition layer covers the shading layer and separates the protective layer from the shading layer under a non-contact state.

a functional layer formed between said partition layer and disposed below the protective layer;

the end portion of the partition layer covering said shading layer and separating said protective layer from said shading layer under a non-contact state.

2. The device as defined in claim 1 , said functional layer being an organic EL light emitting layer.
