The invention provides a flat-plate X ray detector, which comprises a substrate, a photoelectric converting component, a control component and a detecting component, wherein the upper surface of the substrate comprises at least one detecting pixel; the detecting pixel comprises the photoelectric converting component, the control component and a light-transmission component-free area; the lower surface of the substrate comprises the detecting component; and a coverage area of the detecting component comprises the lower surface of a substrate in the component-free area in the detecting pixel on the upper surface. Correspondingly, the invention further provides a preparation method of the flat-pate X ray detector. The detecting components of the flat-plate X ray detector provided by the invention are prepared on the lower surface of the substrate; the pixel area of the detector is not increased; and therefore, the pixel aperture opening ratio cannot be decreased. Data transmission lines of the detecting components and a data transmission line of the flat-plate X ray detector are not on the same surface of the substrate, cannot generate cross talk to the data transmission line of the detector, and have no influence on the image quality obtained by the flat-plate X ray detector.
