Abstract

A display device includes a first substrate including a display region arranged with a plurality of pixels arranged with a light emitting element, a second substrate including a light shielding layer having an aperture part corresponding to the pixel and a color filter being arranged in at least the aperture part and including a pigment layer, a seal component including glass, the seal component bonding the first substrate and second substrate, the display region and color filter facing each other, and being arranged on the exterior side of the color filter, and an inorganic insulation layer covering at least an upper surface and end part of the color filter.

Claims (42)

1. A display device comprising:

a first substrate comprising a display region arranged with a plurality of pixels having a light emitting element;

a second substrate comprising a light shielding layer having an aperture part corresponding to the pixel and a color filter being arranged in at least the aperture part and including a pigment layer;

a seal component comprising glass, the seal component bonding the first substrate and second substrate so that the display region and color filter faces each other, and being arranged on the exterior side of the color filter; and

an inorganic insulation layer covering at least an upper surface and end part of the color filter,

wherein the inorganic insulation layer is in contact with the seal component,

the inorganic insulation layer is provided between the second substrate and the seal component,

the inorganic insulation layer has a first surface and a second surface opposite side of the first surface,

the seal component is in contact with the inorganic insulation layer at the first surface,

the second substrate is in contact with the inorganic insulation layer at the second surface, and

the seal component overlaps with the second substrate in a planar view.

2. The display device according to claim 1 , wherein the light emitting element is exposed in a space part enclosed by the first substrate, the second substrate and seal component.

3. The display device according to claim 2 , wherein a gas with a dew point of −70° C. or less is included in the space part.

4. The display device according to claim 3 , wherein the gas with an oxygen concentration of 1 ppm or less is included in the space part.

5. A display device comprising:

a first substrate comprising a display region arranged with a plurality of pixels having a light emitting element;

a second substrate facing the first substrate, the second substrate being transparent;

a light shielding layer between the first substrate and the second substrate, wherein the light shielding layer has both an aperture part and a slit, the aperture part corresponding to the pixel, and the slit being in a periphery region located in a periphery of the display region; and

a seal component comprising glass, the seal component bonding the first substrate and the second substrate so that the display region and the aperture part face each other.

6. The display device according to claim 5 , wherein the slit is continuously arranged so as to enclose the display region.

7. The display device according to claim 6 , wherein the second substrate includes a color filter having a pigment layer and arranged in at least an aperture part of the light shielding layer; and an inorganic insulation layer covering at least an upper surface and end part of the color filter.

8. The display device according to claim 7 , wherein the light emitting element is exposed in a space part enclosed by the first substrate, the second substrate and the seal component.

9. The display device according to claim 8 , wherein the seal component contacts the inorganic insulation layer.

10. The display device according to claim 8 , wherein a gas with a dew point of −70° C. or less is included in the space part.

11. The display device according to claim 10 , wherein the gas with an oxygen concentration of 1 ppm or less is included in the space part.

12. A display device comprising:

a first substrate comprising a display region arranged with a plurality of pixels having a light emitting element;

a second substrate facing the first substrate, the second substrate being transparent;

a first light shielding layer between the first substrate and the second substrate, the first light shielding layer having an aperture part corresponding to the pixel;

a second light shielding layer on an opposite side of the first light shielding layer with respect to the second substrate, the second light shielding layer being arranged in a periphery region located in a periphery of the display region; and

a seal component comprising glass, the seal component bonding the first substrate and second substrate so that the display region and color filter faces each other.

13. The display device according to claim 12 , wherein the second light shielding layer is continuously arranged so as to enclose the display region.

14. The display device according to claim 12 , further comprising:

a transparent conductive layer arranged in the display region in a surface arranged with the second light shielding layer.

15. The display device according to claim 14 , wherein the transparent conductive layer is a wiring of a touch sensor.

16. The display device according to claim 5 , wherein the slit is arranged in an area sandwiched between the light emitting element and the seal component in a planar view.

17. The display device according to claim 1 , wherein the second substrate is transparent.

18. The display device according to claim 1 , wherein

the seal component, the inorganic insulation layer and the second substrate are overlapped each other in a planar view, and

the inorganic insulation layer is provided between the seal component and the second substrate.

19. The display device according to claim 5 , wherein the second substrate does not have any hole in an area where the second substrate overlaps with the seal component in a planar view.

20. The display device according to claim 12 , wherein the second substrate does not have any hole in an area where the second substrate overlaps with the seal component in a planar view.
