An electronic device is provided. The electronic device includes a display panel and a camera module arranged under the display panel. The display panel may include a first area including a first plurality of pixels having a first pixel density and overlapping the camera module, a second area including a second plurality of pixels having a second pixel density greater than the first pixel density, a first light reflection blocking layer arranged in all or at least a portion of the first area, and a plurality of transparent wiring lines arranged under first organic light-emitting diodes arranged in the first area. The first light reflection blocking layer may be arranged to overlap lower portions of the first organic light-emitting diodes arranged in the first area. The first light reflection blocking layer may be arranged between anode electrodes of the first organic light-emitting diodes and the plurality of transparent wiring lines.
