Abstract: A display panel includes a first unit pixel including a first pixel electrode for emitting red light, a first pixel electrode for emitting blue light, and a first pixel electrode for emitting green light. A second unit pixel neighbors the first unit pixel and includes a second pixel electrode for emitting red light, a second pixel electrode for emitting blue light, and a second pixel electrode for emitting green light. The first unit pixel further includes a first red emission layer disposed on the first pixel electrode for emitting red light.
