a plurality of first pixels and a plurality of second pixels on the first area, each of the plurality of first pixels being configured to emit light of a first color, and each of the plurality of second pixels being configured to emit light of a second color; and
a plurality of third pixels and a plurality of fourth pixels on the second area, each of the plurality of third pixels being configured to emit light of the first color, and each of the plurality of fourth pixels being configured to emit light of the second color,
wherein a first virtual line passing through a center of an emission area of each of at least two the first pixels and a center of an emission area of each of at least two third pixels is parallel to a first direction, and
a second virtual line passing through a center of an emission area of each of at least two second pixels and a center of an emission area of each of at least two fourth pixels crosses the first direction.

2. The display device of claim 1 , further comprising a camera under the substrate in the second area.

3. The display device of claim 1 , wherein an angle between the first virtual line and the second virtual line is 45° or less.

4. The display device of claim 1 , wherein each of the plurality of first pixels and each of the plurality of third pixels are configured to emit green light.

5. The display device of claim 4 , wherein each of the plurality of second pixels and each of the plurality of fourth pixels are configured to emit red or blue light.

6. The display device of claim 1 , wherein a size of the emission area of each of the plurality of first pixels is less than a size of the emission area of each of the plurality of second pixels, and a size of the emission area of each of the plurality of third pixels is less than a size of the emission area of each of the plurality of fourth pixels.

7. The display device of claim 1 , further comprising a plurality of fifth pixels on the first area and configured to emit light of a third color, and a plurality of sixth pixels on the second area and configured to emit light of the third color.

8. The display device of claim 7 , wherein a third virtual line passing through a center of an emission area of each of at least two fifth pixels and a center of an emission area of each of at least two sixth pixels crosses the first direction.

9. The display device of claim 8 , wherein the second virtual line and the third virtual line cross each other.

10. The display device of claim 9 , wherein a fourth virtual line passing through the center of the emission area of each of at least two fourth pixels and a center of an emission area of each of at least two sixth pixels is spaced from and substantially parallel to the first virtual line, and the plurality of first pixels is not on the fourth virtual line.

11. The display device of claim 1 , wherein a size of the e mission area of each of the plurality of second pixels is greater than a size of the emission area of each of the plurality of first pixels.

12. The display device of claim 1 , wherein a light transmittance of the transmission area is between about 30% and about 90%.

a plurality of first pixels configured to emit green light and a plurality of second pixels configured to emit blue light, the plurality of first pixels and the plurality of second pixels being on the first area; and
a plurality of third pixels configured to emit green light and a plurality of fourth pixels configured to emit blue light, the plurality of third pixels and the plurality of fourth pixels being on the second area,
wherein a first virtual line passing through a portion of an emission area of each of at least two first pixels and a portion of an emission area of each of at least two third pixels is parallel to a first direction,
wherein a second virtual line passing through a portion of an emission area of each of at least two second pixels and a portion of an emission area of each of at least two fourth pixels crosses the first direction, and
wherein an angle between the first virtual line and the second virtual line is 45° or less.

14. The display device of claim 13 , further comprising a camera under the substrate in the second area.

15. The display device of claim 13 , wherein a size of the emission area each of the plurality of second pixels is greater than a size of the emission area of each of the plurality of first pixels.

16. The display device of claim 15 , wherein a size of the emission area of each of the plurality of first pixels is greater than a size of the emission area of each of the plurality of third pixels.

17. The display device of claim 13 , wherein a light transmittance of the transmission area is between about 30% and about 90%.

18. A display device comprising:
a substrate including, in a plan view, a first area and a second area adjacent to the first area, the second area including a transmission area;
a plurality of first pixels configured to emit green light, a plurality of second pixels configured to emit blue light and a plurality of fifth pixels configured to emit red light, the plurality of first pixels, the plurality of second pixels and the plurality of fifth pixels being on the first area; and
