Abstract

A display device is provided including a first substrate comprising a resin material provided with a plurality region provided with a plurality of pixels including a display device, and a second substrate provided facing the first substrate and installed with the pixel region, wherein an outer periphery side surface of the first substrate having a taper shape and including a barrier layer covering an upper layer, lower layer and the outer periphery side surface of the first substrate.

First claim

What is claimed is:

1. A display device comprising:
a substrate including a resin material;
a pixel region on the substrate, the pixel region having a plurality of pixels arranged in a matrix;
an end surface region around the pixel region;
a first barrier layer covering a lower surface of the substrate; and
a second barrier layer covering an upper surface of the substrate,

wherein the end surface region has an outer periphery side surface of the substrate having a taper shape, and
the second barrier layer covers the upper surface of the substrate and the outer periphery side surface of the substrate continuously.

2. The display device according to claim 1 , wherein
the second barrier layer contacts the first barrier layer around the outer periphery side surface of the substrate.

3. The display device according to claim 1 , wherein
each of the first barrier layer and the second barrier layer includes at least one of silicon nitride, silicon oxynitride, silicon oxide and aluminum oxide.

4. The display device according to claim 1 , further comprising a passivation layer covering the pixel region, wherein
each of the plurality of pixels has an organic El layer on the second barrier layer, and
the passivation layer is on the organic EL layer.

5. The display device according to claim 4 , wherein
the passivation layer includes silicon nitride.

6. The display device according to claim 4 , further comprising a filler material covering the pixel region, wherein
the filler material contacts the passivation layer on the pixel region.

7. The display device according to claim 6 , wherein
the filler material includes a resin material.
