    Abstract: A display panel and a method for fabricating the same are discussed. The display panel can include a first area in which pixels are disposed, and a second area in which pixels having lower pixels per inch (PPI) than the first area are disposed and a plurality of light-transmitting portions are disposed. The light-transmitting portions include circular or elliptical light-transmitting portions arranged in a zigzag pattern along a second direction crossing a first direction in the second area. Each of the pixel groups in the second area includes a second electrode, and the second electrode is removed from the light-transmitting area to expose light-transmitting portions.
