    Abstract: A display device includes first and second unit pixels adjacent to each other in a first direction. Each of the first and second unit pixels includes a first group disposed in a first row and a second group disposed in a second row spaced apart from the first row. The first group includes a first light emitting area emitting a first light, and a second light emitting area emitting a second light. The second group includes a light receiving area and third and fourth light emitting areas spaced apart from each other with the light receiving area interposed therebetween and emitting the third light. The fourth light emitting area of the first unit pixel and the third light emitting area of the second unit pixel are spaced apart from each other by a distance from about 25 micrometers to about 100 micrometers in the first direction.
