An array substrate for a digital X-ray detector, and an X-ray detector including the same are disclosed, which reduce or minimize a contact resistance between a bias electrode and a PIN diode, and also improve a fill factor of the PIN diode. In the array substrate, a dual bias electrode in which a second bias electrode formed of a transparent conductive material is connected to a first bias electrode that is additionally connected to an upper electrode of the PIN diode, such that total resistance of the bias electrodes is reduced and a line width of the first bias electrode formed of a non-transparent material is reduced, resulting in an increased fill factor of the PIN diode.

An array substrate for a digital X-ray detector can include a base substrate; a thin film transistor disposed on the base substrate; a PIN diode including a lower electrode electrically connected to the thin film transistor, a first PIN layer disposed on the lower electrode, and an upper electrode disposed on the first PIN layer; a second PIN layer spaced apart from the PIN diode, the second PIN layer being disposed on the thin film transistor; and a bias electrode electrically connected to the upper electrode.

Array substrate for digital x-ray detector, digital x-ray detector including the same, and method for manufacturing the same

An array substrate for a digital X-ray detector and the digital X-ray detector including the same are disclosed. The array substrate effectively protects a PIN diode from external moisture or water, maximizes a light transmission region of a PIN diode, and reduces resistance by maximizing the region of a bias wiring. To this end, a closed-loop bias electrode formed to cover a circumferential surface of a PIN diode is used. In detail, the bias electrode includes a closed loop portion and a contact extension portion. The contact extension portion extends from one end of the closed loop portion so as to directly contact an upper electrode, and includes a hollow part therein.
