7. The display panel of claim 6 , wherein the transparent organic or inorganic material is the same material as a layer included in the first pixel or the second pixel.
8. The display panel of claim 4 , wherein the second high-transmission portion is provided at a position corresponding to the light-transmitting area in the second area.
9. The display panel of claim 4 , wherein each of the first high-transmission portion and the second high-transmission portion has a tapered cross-section, and in a cross-sectional view, a lateral side of the first high-transmission portion is collinear with a lateral side of the second high-transmission portion.
10. The display panel of claim 4 , wherein the first high-transmission portion has a forward-tapered cross-section and the second high-transmission portion has a reverse-tapered cross-section.
11. The display panel of claim 4 , wherein the first high-transmission portion has a reverse-tapered cross-section and the second high-transmission portion has a forward-tapered cross-section.
12. The display panel of claim 1 , wherein the polarizing plate includes a first protective layer, a second protective layer, and a polarizer disposed between the first protective layer and the second protective layer, and
wherein the light-transmitting pattern is formed in the polarizer.
13. The display panel of claim 12 , wherein the light-transmitting pattern includes an opening formed in the polarizer.
14. The display panel of claim 13 , wherein the first protective layer includes a protrusion inserted into the opening.
15. The display panel of claim 12 , wherein the light-transmitting area includes a discolored area formed in the polarizer.
16. The display panel of claim 15 , wherein the discolored area is an area in which an iodine compound of the polarizer is decomposed.
17. The display panel of claim 1 , further comprising an anti-reflection layer disposed in the second area and provided to reduce diffusion or reflection of incident light.
18. The display panel of claim 17 , wherein the anti-reflection layer is located on at least one of an upper portion of an interlayer insulating layer, a lower portion of the substrate, an upper portion of the polarizing plate, and a lower portion of the polarizing plate.
19. A display device comprising a display panel:
wherein the display panel comprises:
a substrate having a first area in which first pixels are disposed and a second area in which second pixels and a light-transmitting area are disposed between the second pixels; and
a polarizing plate disposed on the substrate and including a light-transmitting pattern disposed above the light-transmitting area and having a light transmittance higher than a light transmittance of a remaining area in the polarizing plate,
wherein the substrate includes a high-transmission portion overlapped with the second area, and
wherein a light transmittance of light passing through the high-transmission portion is higher than a light transmittance of light passing through an area of lower light transmittance corresponding to the second area.
20. The display device of claim 19 , wherein the second area overlaps with a camera module, and a resolution of the second pixels disposed in the second area is lower than a resolution of the first pixels disposed in the first area.
