An X-ray image detector system includes: a plurality of scanning lines; a plurality of signal lines formed so as to intersect the scanning lines; and a plurality of pixel parts, each of which is formed at a corresponding one of the intersections between the scanning lines and the signal lines so as to form an array; each of said pixel parts having an X-ray-to-charge converting part for converting an incident X-ray to an electric charge, a pixel electrode for receiving the electric charge from the X-ray-to-charge converting part, and a switching element which is operated on the basis of a signal of a corresponding one of the scanning lines, one end of the switching element being connected to the pixel electrode, and the other end of the switching element being connected to a corresponding one of the signal lines, wherein the X-ray-to-charge converting part includes at least a first X-ray-to-charge converting film, and a second X-ray-to-charge converting film having a lower resistivity than that of the first X-ray-to-charge converting film. Thus, it is possible to provide an X-ray image detector system capable of detecting an image even if X-ray irradiation is weak.

An image detection device having pixel electrodes arrayed in a matrix in an image detection area on one face of an insulating film. A shield electrode is disposed in the peripheral area on the outside the detection area, and a driving circuit for driving the pixel electrodes and wires connecting the pixel electrodes are provided on the other face of the insulating film. The driving circuit may be provided in the peripheral area. The wires disposed in the peripheral area are shielded by the shield electrode to prevent electrostatic breakdown even when a large current flows through a photoelectric converting film, thereby to improve reliability by preventing dielectric breakdown and to accommodate a large dynamic range of incident light.

The image display apparatus is capable of displaying an image on a large screen in which non-display regions are completely eliminated or minimized. The image display apparatus comprises an opposite board in which common electrodes made of transparent conductive resin are respectively formed on both surfaces of a transparent substrate. A plurality of array boards in each of which semiconductor element and a signal line are formed on a transparent substrate are arranged on both surfaces of the opposite board, such that display regions of end portions of the array boards face each other a sandwich of the opposite board inserted therebetween. Frame-like sealing members made of transparent resin are respectively inserted in clearances between the opposite board and the array boards. Liquid crystal is enclosed in each of spaces surrounded by the frame-like sealing members between the opposite board and the array boards.
