A digital X-ray detector panel and an X-ray system including the same are disclosed, which include a Gate-In-Panel (GIP) structure in which a gate driver element is embedded in the panel, reduce production costs, and are easily applied to a narrow bezel and a flexible panel. A light shielding layer including tungsten or copper having X-ray shielding characteristics is disposed in a gate driver element mounting region, minimizing X-ray damage to the gate driver element embedded in the panel. In order to prevent not only damage caused by X-rays vertically incident upon the panel, but also damage caused by X-rays incident upon the panel at an incidence angle of less than 90°, the light shielding layer extends to overlap at least a portion of the gate driver element mounting region.
