Display device

A display device comprising:

• a substrate including a first display area and a second display area including a transmission area;
• first pixels in the first display area;
• and
• second pixels in the second display area,
• wherein a distance between a first sub-pixel from among the first pixels, the first sub-pixel being adjacent to the boundary area between the first display area and the second display area and emitting light of a first color, and a second sub-pixel from among the second pixels, the second sub-pixel being adjacent to the boundary area, emitting light of a color different from the first color, and through which a virtual line passing through a center of the first sub-pixel passes, is greater than or equal to a minimum value among gap values of a pixel-defining layer between the first pixels and gap values of a pixel-defining layer between the second pixels.

• wherein a center distance between a first sub-pixel from among the first pixels, the first sub-pixel being adjacent to a boundary area between the first display area and the second display area and emitting light of a first color, and a second sub-pixel from among the second pixels, the second sub-pixel being adjacent to the boundary area, emitting light of the first color, and through which a virtual line passing through a center of the first sub-pixel passes, is within a certain range of twice a pixel pitch.
