1. A display panel, comprising:
first, second and third scan lines;
a first light emitting pixel which is electrically connected to the first scan line and arranged in a first row;
a second light emitting pixel arranged in a second row;
a third light emitting pixel which is electrically connected to the third scan line and arranged in a third row; and
a light sensing pixel arranged in the second row,
wherein the second light emitting pixel and the light sensing pixel are commonly electrically connected to the second scan line,
wherein the light sensing pixel comprises:
a photo sensor including a first electrode and a second electrode; and
a first sensing transistor including a first electrode, a second electrode connected to the first electrode of the photo sensor and a gate electrode,
wherein the second light emitting pixel and the gate electrode of the first sensing transistor are commonly electrically connected to the second scan line.
