    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: 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, 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.
