Abstract

A display device includes a circuit substrate that is formed of a plurality of layers stacked on each other and including a self-luminous element layer that emits light of controlled luminance from each of a plurality of unit pixels and a counter substrate that includes a light shielding layer that shields the light from the self-luminous element layer and so provided as to face the circuit substrate, and the light shielding layer has an opening so formed in an area shifted from an area facing the self-luminous element layer toward an edge of the counter substrate and along the edge of the counter substrate.

First claim

What is claimed is:

1. A display device comprising:
a circuit substrate that is formed of a plurality of layers stacked on each other and including a self-luminous element layer that emits light of controlled luminance from each of a plurality of unit pixels; and
a counter substrate that includes a light shielding layer that shields the light from the self-luminous element layer and so provided as to face the circuit substrate,
wherein the light shielding layer has an opening so formed in an area shifted from an area facing the self-luminous element layer toward an edge of the counter substrate and along the edge of the counter substrate,
wherein at least one of the plurality of layers includes a groove formed along an edge of the circuit substrate,
the opening is provided in a position shifted from an inner surface that is one of inner surfaces of the groove and is closer to the self-luminous element layer toward the edge of the counter substrate, and
wherein the plurality of layers are configured that a layer provided on an upper side is made of a material having an optical refractive index smaller than an optical refractive index of a material of which a layer provided in a lower side is made.

2. The display device according to claim 1 ,
wherein at least one of the plurality of layers has a cut section cut along an edge of the circuit substrate, and
the opening is provided in a position shifted from a cut surface that is one of cut surfaces of the cut section and is closer to the self-luminous element layer toward the edge of the counter substrate.

3. The display device according to claim 2 , wherein the cut surface closer to the self-luminous element layer is an inclining surface.

4. The display device according to claim 2 ,
wherein a bank layer that separates the plurality of unit pixels from one another is disposed in the circuit substrate, and
the at least one layer includes the bank layer.

5. The display device according to claim 4 ,
wherein an organic layer is disposed on a side opposite the self-luminous element layer with respect to the bank layer, and
the at least one layer includes the organic layer.

6. The display device according to claim 1 , wherein the inner surface closer to the self-luminous element layer is an inclining surface.

7. The display device according to claim 1 ,
wherein a sealing film that covers the self-luminous element layer is disposed on a side that is one of two sides of the self-luminous element layer and faces the counter substrate, and
the at least one layer includes the sealing film.

8. The display device according to claim 1 , further comprising a seal member provided along the opening and between the circuit substrate and the counter substrate.

9. The display device according to claim 1 ,
further comprising a seal member provided along the opening and between the circuit substrate and the counter substrate,
wherein the seal member is made of a material having an optical refractive index smaller than an optical refractive index of a material of an uppermost layer of the plurality of layers.

10. The display device according to claim 1 , wherein the counter substrate includes a color filter layer.
