Abstract

A display device includes a substrate having a hole, a plurality of pixels provided to the substrate, and a plurality of light emitting elements provided to the respective pixels. the light emitting elements include a first light emitting element having a predetermined chip size, and a second light emitting element having a chip size smaller than the chip size of the first light emitting element, the first light emitting element and the second light emitting element emit light in a common color, and the light emitting elements disposed around the hole include at least one second light emitting element.

Claims (52)

1 . A display device comprising:

a substrate having a hole;

a plurality of pixels provided to the substrate; and

a plurality of light emitting elements provided to the respective pixels, wherein

the light emitting elements include:

a first light emitting element having a predetermined chip size; and

a second light emitting element having a chip size smaller than the chip size of the first light emitting element,

the first light emitting element and the second light emitting element emit light in a common color, and

the light emitting elements disposed around the hole include at least one second light emitting element.

2 . The display device according to the claim 1 , wherein

the substrate includes:

a display region provided with the pixels; and

a peripheral region surrounding the display region,

a boundary line between the display region and the peripheral region has a recessed line recessed toward the display region,

the display region includes a first region and a second region sandwiching the recessed line, and

the first region and the second region are provided with the second light emitting element.

3 . A display device comprising:

a substrate having a hole;

a plurality of pixels provided to the substrate;

a plurality of light emitting elements provided to the respective pixels; and

a cathode electrode covering the light emitting elements, wherein

the light emitting elements disposed around the hole include at least one third light emitting element,

the third light emitting element comprises a p-type cladding layer, an active layer, an n-type cladding layer, and a high-resistance layer stacked in order on the substrate,

sheet resistance of the high-resistance layer is higher than sheet resistance of the n-type cladding layer,

the high-resistance layer has an opening at a center, and

the cathode electrode covers the high-resistance layer and is directly coupled to a center part of the n-type cladding layer through the opening of the high-resistance layer.

4 . The display device according to the claim 3 , wherein

the substrate includes:

a display region provided with the pixels; and

a peripheral region surrounding the display region,

a boundary line between the display region and the peripheral region has a recessed line recessed toward the display region,

the display region includes a first region and a second region sandwiching the recessed line, and

the first region and the second region are provided with the third light emitting element.

5 . A display device comprising:

a substrate including a display region provided with a plurality of pixels;

a first light emitting element coupled to a first gate line in the display region; and

a second light emitting element coupled to a second gate line in the display region, wherein

a wiring length of the second gate line in the display region is shorter than a wiring length of the first gate line in the display region,

the first light emitting element and the second light emitting element emit light in a common color, and

a chip size of the second light emitting element is smaller than a chip size of the first light emitting element.

6 . The display device according to claim 5 , wherein

the substrate has a hole, and the hole is a notch formed in a recessed shape along a side surface of the substrate,

the second light emitting element is disposed near the notch, and

the first light emitting element is disposed farther away from the notch than the second light emitting element.

7 . The display device according to claim 5 , wherein

the substrate has a hole, and the hole is a through hole passing through the substrate and formed in the display region,

the second light emitting element is disposed near the through hole, and

the first light emitting element is disposed farther away from the through hole than the second light emitting element.

8 . The display device according to claim 5 , wherein

the substrate has a hole, and the hole is a transparent region not provided with the pixels in the display region,

the second light emitting element is disposed near the transparent region, and

the first light emitting element is disposed farther away from the transparent region than the second light emitting element.
