1. A display panel comprising a plurality of pixel groups disposed in a display area of a substrate,
wherein each of the plurality of pixel groups is arranged in a 2×2-matrix and includes a first unit pixel disposed in a first quadrant of the matrix, a second unit pixel disposed in a second quadrant of the matrix, a third unit pixel disposed in a third quadrant of the matrix, and a fourth unit pixel disposed in a fourth quadrant of the matrix,
wherein the first unit pixel includes a first red pixel electrode for emitting red light, a first blue pixel electrode for emitting blue light, and a first green pixel electrode for emitting green light, the second unit pixel includes a second red pixel electrode for emitting red light, a second blue pixel electrode for emitting blue light, and a second green pixel electrode for emitting green light, the third unit pixel includes a third red pixel electrode for emitting red light, a third blue pixel electrode for emitting blue light, and a third green pixel electrode for emitting green light, and the fourth unit pixel includes a fourth red pixel electrode for emitting red light, a fourth blue pixel electrode for emitting blue light, and a fourth green pixel electrode for emitting green light,
wherein a distance between the first red pixel electrode and the second red pixel electrode, in a row direction, is the same as a distance between the third red pixel electrode and the fourth red pixel electrode,
wherein a distance between the first blue pixel electrode and the second blue pixel electrode, in the row direction, is less than a distance between the third blue pixel electrode and the fourth blue pixel electrode,
wherein the first unit pixel and the second unit pixel each further include: a first blue emission layer disposed over both the first blue pixel electrode and the second blue pixel electrode,
wherein a first portion of the first blue emission layer corresponds to the first blue pixel electrode, and a second portion of the first blue emission layer corresponds to the second blue pixel electrode,
wherein the display panel further comprises a pixel-defining layer including a first opening and a second opening, the first opening defining an emission area of the first blue pixel electrode, and the second opening defining an emission area of the second blue pixel electrode, and
wherein at least a portion of the first blue emission layer is disposed on a portion of the pixel-defining layer that is between the first blue pixel electrode and the second blue pixel electrode.
