Abstract:
1. An X-ray detector, comprising: a substrate; an oxide semiconductor transistor on the substrate, the oxide semiconductor transistor including a source electrode, a gate electrode, a drain electrode, and a channel of an oxide semiconductor material; a signal storage capacitor on the substrate, the signal storage capacitor including an upper electrode and a lower electrode; a pixel electrode on the upper electrode and connected to the upper electrode; a first diffusion-prevention layer on the pixel electrode; a photoconductor on the first diffusion-prevention layer; a common electrode on the photoconductor; and a signal processor connected to the drain electrode; wherein the oxide semiconductor transistor and the signal storage capacitor are parallel to each other on the substrate, wherein the first diffusion-prevention layer is of a conductive polymer or a conductive oxide semiconductor, and wherein the first diffusion-prevention layer prevents diffusion of constituents of the photoconductor into the pixel electrode.
