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: 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.

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 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.
