a transmission area disposed in the second display area, the transmission area being disposed between two adjacent emission areas, of the plurality of emission areas, disposed in the second display area;
an encapsulation layer disposed on the plurality of emission areas;
an input sensing layer disposed on the encapsulation layer and including a plurality of touch electrodes; and
a reflection prevention layer disposed on the input sensing layer and including a light blocking layer and a plurality of color filters, wherein the light blocking layer includes a plurality of opening portions overlapping the plurality of emission areas, and the plurality of color filters overlap the plurality of emission areas,
wherein each of the plurality of touch electrodes includes a conductive mesh pattern including a plurality of mesh holes, and
wherein a particular emission area, of the plurality of emission areas, disposed in the second display area, the transmission area, and a light blocking area are located in a same mesh hole, of the plurality of mesh holes, in a plan view, and
wherein the particular emission area is a single emission area.

2. The display panel of claim 1 , wherein the light blocking layer overlaps the conductive mesh pattern and includes a partition portion extending between the particular emission area and the transmission area located in the same mesh hole aid corresponding to a part of the light blocking area.

3. The display panel of claim 2 , wherein the partition portion of the light blocking layer is overlapped by a color filter, of the plurality of color filters, that is disposed on the particular emission area.

4. The display panel of claim 2 , wherein each of the plurality of emission areas includes:
a light-emitting diode including a first electrode, an emission layer disposed on the first electrode, and a second electrode disposed on the emission layer; and
a bank layer covering an edge of the first electrode and including a first opening overlapping the first electrode and a second opening corresponding to the transmission area,
wherein a width of each of the plurality of emission areas is defined by the first opening of the bank layer.

5. The display panel of claim 4 , wherein the bank layer includes a light blocking material.

6. The display panel of claim 4 , wherein the light blocking layer includes an opening portion corresponding to the transmission area, and a width of the second opening of the bank layer is less than a width of the opening portion of the light blocking layer.

7. The display panel of claim 4 , wherein the light blocking layer includes an opening portion corresponding to the transmission area, and a width of the second opening of the bank layer is greater than a width of the opening portion of the light blocking layer.

8. The display panel of claim 1 , wherein a number of emission areas, of the plurality of emission areas, disposed in the first display area is the same as a number of emission areas, of the plurality of emission areas, disposed in the second display area, for a given area.

9. The display panel of claim 1 , wherein the light blocking layer includes a transmissive opening portion corresponding to the transmission area,
wherein the reflection prevention layer further includes an overcoat layer disposed on the plurality of color filters and the light blocking layer, and
wherein a portion of the overcoat layer at least partially fills the transmissive opening portion of the light blocking layer.

10. The display panel of claim 1 , wherein the plurality of emission areas includes adjacent emission areas disposed in the second display area and emitting light of different colors from each other,
wherein the plurality of color filters includes a first color filter and a second color filter respectively disposed on the adjacent emission areas, and
wherein the first color filter and the second color filter overlap each other on a portion of the light blocking layer, the portion corresponding to a space between the adjacent emission areas.

11. The display panel of claim 1 , wherein the plurality of emission areas includes adjacent emission areas disposed in the second display area and emitting light of different colors from each other,
wherein the plurality of color filters includes a first color filter and a second color filter respectively disposed on the adjacent emission areas, and
wherein the first color filter and the second color filter overlap a third color filter, of the plurality of color filters, disposed on a portion of the light blocking layer, the portion corresponding to a space between the adjacent emission areas, wherein the third color filter has a different color from the first and second color filters.

12. The display panel of claim 11 , wherein a conductive line corresponding to any one of the touch electrodes, of the plurality of touch electrodes, is disposed below the portion of the light blocking layer,
wherein, on the portion of the light blocking layer, a first overlapping area, between the first color filter and the third color filter, does not overlap the conductive line, and
wherein a second overlapping area, between the second color filter and the third color filter, does not overlap the conductive line.

13. A display apparatus, comprising:
a display panel comprising: a plurality of emission areas arranged in a first display area and a second display area, each of the plurality of emission areas being configured to emit light of a single color, the second display area at least partially surrounded by the first display area; and a transmission area disposed between two adjacent emission areas, of the plurality of emission areas, in the second display area; and
a first component disposed below the display panel and corresponding to the second display area,
