    Abstract: An electronic apparatus includes a display panel and a digitizer disposed under the display panel and provided with a plurality of holes defined therethrough to overlap the folding region. The digitizer includes a first base layer, first loop coils including first first coils and second first coils, a second base layer disposed under the first base layer, second loop coils including first second coils and second second coils, and interposed between the first base layer and the second base layer, and bridge patterns. A first first line included in one bridge pattern is connected to a corresponding first first coil, and a second first line included in the bridge pattern is connected to the second first coil which receives a signal the same as a signal of the first first coil.
