Abstract: A display device includes a display panel including a gate line, a data line, and a pixel electrically connected to the gate line and the data line and that displays an image based on input image data, a gate driver which outputs a gate signal to the gate line, a data driver which outputs a data voltage to the data line, and a driving controller which controls the gate driver and the data driver. The pixel includes a first pixel that emits light in a first mode and does not emit light in a second mode and a second pixel that emits light in both the first mode and the second mode, where the second pixel has a narrower viewing angle than the first pixel. The gate line includes a first gate line connected only to the first pixel and a second gate line connected only to the second pixel.
