Abstract: Disclosed is a method of determining an X-ray image for a liquid crystal X-ray detector. The method includes a first step of measuring a reference transmittance of a pixel while varying a bias voltage in a state in which an X-ray sensing liquid crystal panel is not irradiated with an X-ray, a second step of separating electrons and holes in the X-ray sensing liquid crystal panel by applying a separation voltage and irradiating the X-ray sensing liquid crystal panel with an X-ray, a third step of measuring a detection transmittance of a pixel by applying a measurement voltage to the X-ray sensing liquid crystal panel, a fourth step of deriving a bias voltage of a reference transmittance of the pixel corresponding to the detection transmittance, and a fifth step of determining an X-ray image of the pixel by subtracting the measurement voltage from the bias voltage derived in the fourth step.

Abstract: Disclosed is a liquid crystal X-ray detector capable of obtaining a complete X-ray image of a subject without having to combine smaller partial X-ray images while using an imaging lens much smaller than a liquid crystal layer. The liquid crystal X-ray detector includes a photoconductor unit including a photoconductive layer, a liquid crystal unit provided on the photoconductor unit and including a liquid crystal layer, a read beam output unit outputting a read beam toward the liquid crystal layer, and an imaging lens disposed on a light path in front of the liquid crystal layer. The read beam output unit emits scattered or plane light. The imaging lens has a long axis length that is equal to or smaller than one half of the long axis length of the liquid crystal layer.

Abstract: Disclosed is a liquid crystal X-ray detector in which only one substrate is used to make a liquid crystal unit by forming one of two alignment films for holding a liquid crystal layer therebetween on a selenium layer. Further disclosed is a method of manufacturing the same. The liquid crystal X-ray detector includes a photoconductor unit and a liquid crystal unit provided on the photoconductor unit. The photoconductor unit includes a first substrate, a selenium layer formed on the first substrate, and a first alignment film formed on the selenium layer. The first alignment film is formed of parylene deposited at a temperature lower than 45° C. in a vacuum atmosphere. The liquid crystal unit includes a second substrate, a second alignment film formed on the second substrate and opposed to the first alignment film, and a liquid crystal layer provided between the first alignment film and the second alignment film.
