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.

    摘要： When using a flexible substrate to protect and support various components of an organic light emitting display device, among components including driving elements disposed on each of pixels of the organic light emitting display device, components where a high-level signal is applied during an emission period are grouped and are disposed on one side of the pixels. Further, components where a low-level signal is applied during the emission period are grouped and are disposed on the other side of the pixels. Accordingly, an electric field occurring due to a potential difference in the flexible substrate is minimized and shifting of a threshold voltage Vth of a thin-film transistor may be minimized. Thus, an OLED without an after-image can be provided.
