Abstract

A display device is provided including a display region arranged with a plurality of the pixels in a matrix, the plurality of pixels including a light emitting region, a first light shielding layer, and a second light shielding layer, wherein the first light shielding layer includes a plurality of first apertures opening the light emitting region, and a plurality of second apertures opening a non-light emitting region between the plurality of the pixels, and the second light shielding layer is arranged below the first light shielding layer and includes a plurality of third apertures opening the light emitting region, the second light shielding layer being arranged with a light shielding region below the second apertures.

Claims (57)

1. A display device, comprising:

a display region arranged with a plurality of pixels in a matrix, the plurality of the pixels including a light emitting region;

a first light shielding layer; and

a second light shielding layer;

wherein

the first light shielding layer includes a plurality of first apertures opening the light emitting region, and a plurality of second apertures opening a non-light emitting region between the plurality of the pixels; and

the second light shielding layer is arranged below the first light shielding layer and includes a plurality of third apertures opening the light emitting region, the second light shielding layer being arranged with a light shielding region below the second apertures.

2. The display device according to claim 1 , wherein the light emitting region includes a color filter, the first light shielding layer is arranged above the color filter and the second light shielding layer is arranged below the color filter.

3. The display device according to claim 2 , wherein the color filter includes a plurality of color filters, and

the plurality of the color filters are separated below the second apertures.

4. The display device according to claim 1 , wherein the plurality of the pixels include a first pixel and a second pixel adjacent to the first pixel, and at least two of the second apertures are arranged between the first pixel and the second pixel.

5. The display device according to claim 1 , wherein the plurality of the

pixels include a first pixel, a second pixel adjacent to the first pixel, and a third pixel adjacent to the first pixel on a different side to the second pixel;

the plurality of the second apertures include a 1-2 intermediary aperture located between the first pixel and the second pixel, and a 1-3 intermediary aperture located between the first pixel and the third pixel;

the 1-2 intermediary aperture includes a first length direction; and

the 1-3 intermediary aperture includes a second length direction different to the first length direction.

6. A display device, comprising:

a display region arranged with a plurality of pixels in a matrix, the plurality of the pixels including a light emitting region; and

a first light shielding layer;

wherein

the first light shielding layer includes a plurality of first apertures opening the light emitting region, and a plurality of second apertures opening a non-light emitting region between the plurality of the pixels;

each of the first apertures forms each of L character shapes;

the plurality of the first apertures include four of the first apertures consisting of four of the L character shapes;

the four of the first apertures are arranged in two adjacent rows and columns;

the four of the L character shapes include a first pair of the L character shapes and a second pair of the L character shapes;

the first pair of the L character shapes are arranged point symmetrically; and

the second pair of the L character shapes are arranged point symmetrically.

7. The display device according to claim 6 , further comprising a second light shielding layer,

wherein the second light shielding layer includes a plurality of third apertures opening the light emitting region and has a light shielding region below the plurality of the second apertures.

8. A display device, comprising:

a first substrate;

a display region arranged above the first substrate including a plurality of pixels arranged in a matrix, the plurality of the pixels including a light emitting region;

a first light shielding layer; and

a third light shielding layer;

wherein

the first light shielding layer includes a plurality of first apertures opening the light emitting region;

at least one part of the third light shielding layer is arranged on an opposite side of the light shielding layer from the first substrate; and

the third light shielding layer includes a plurality of fourth apertures which are larger in number than the plurality of the first apertures.

9. The display device according to claim 8 , wherein a sheet with translucency is arranged on an opposite side of the first light shielding layer from the first substrate, and the third light shielding layer is formed in the sheet.

10. The display device according to claim 9 , wherein the sheet is arranged in contact with the first light shielding layer.

11. The display device according to claim 9 , further comprising a second substrate facing the first substrate,

wherein the first light shielding layer is located between the first substrate and the second substrate, and

the sheet is located on an opposite side of the second substrate from the first substrate.

12. The display device according to claim 8 , wherein the plurality of the fourth apertures include an aperture located between the plurality of the pixels.

13. The display device according to claim 8 , wherein the plurality of the fourth apertures includes a plurality of apertures overlapping one light emitting region.

14. The display device according to claim 8 , wherein a light emitting layer, a pixel electrode and a common electrode are arranged in the first substrate,
