Abstract: Disclosed are a thin-film transistor array substrate for a high-resolution digital X-ray detector and a high-resolution digital X-ray detector including the same, in which a photo-sensitivity is improved by increasing a fill factor, a stability of the PIN diode is improved, and generation of parasitic capacitance is reduced or minimized. In one embodiment, the PIN diode maximally extends so that electrodes and contact holes of the thin-film transistor is disposed inside the PIN diode. A planarization layer of organic material is present between the electrodes or wirings. Further, a light receiving region of the PIN diode is increased or maximized by positioning the bias line to overlap the data line or the gate line so as not to overlap with the PIN diode.

Abstract: The present disclosure relates to a digital X-ray detector, which includes a base substrate; a metal layer disposed on a bottom face of the base substrate; an elements-array disposed on a top face of the base substrate; a ground electrode disposed on a top face of the base substrate and electrically connected to the elements-array; a scintillator layer disposed on the elements-array; and a reflective plate disposed on the scintillator layer. Thus, a static-electricity discharge path along which static-electricity from the reflective plate moves through the ground electrode to the metal layer may be secured. This may increase or maximize an effective ground region, such that the static-electricity generated from the top and bottom of the digital X-ray detector can be more efficiently discharged out.

Abstract: 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.

Abstract: An array substrate for a digital X-ray detector, a digital X-ray detector including the same, and a method for manufacturing the same are disclosed. The array substrate reduces a step difference of a PIN diode, removes a bent part from a lower part to reduce characteristic deterioration of the PIN diode, and increases the size of a formation region of the PIN diode to increase a fill factor. To this end, the array substrate allows a source region of an active layer included in a thin film transistor to be in surface contact with a lower electrode of the PIN diode, and disposes the lower electrode over a planarized source region or a base substrate, such that a step difference of the PIN diode is reduced and fill factor is improved.

Abstract: Provided is a method of manufacturing new liquid crystal display device according to an embodiment of the present invention. Firstly, an alignment film is formed on a substrate. The alignment film is divided into a first alignment film formed using, as a precursor, liquid-state polyimide that contains a photodecomposition substance and a second alignment film formed using, as a precursor, a polyamic acid that does not contain a photodecomposition substance. UV light is irradiated to the alignment film, and decomposed substances formed by irradiation of the UV light is removed by an at least two-step removing process. By the method of manufacturing a liquid crystal display device according to the exemplary embodiment of the present disclosure, bright spots are minimized in pixels and a brightness of black is lowered, so that a liquid crystal display device with a high contrast ratio can be realized.

Abstract: An alignment film for liquid crystal display device includes a first portion positioned towards to the liquid crystal layer and a second portion positioned away from the liquid crystal layer. The first portion provides improved anchoring force while the second portion exhibits a lower volume resistance than the first portion. Thus, AC image sticking and DC image sticking can be minimized at the same time.
