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. The second unit pixel further includes a second red emission layer disposed on the second pixel electrode for emitting red light. The first red emission layer is spaced apart from the second red emission layer in the first direction.
