In a two-dimensional image detecting device, an active-matrix substrate and
an opposing substrate are bonded to each other via conductive connecting
members and space keeping members, that are disposed respectively for
pixels, such that pixel electrodes and electrical charge collecting
electrodes oppose each other. The pixel electrodes are formed on the
active-matrix substrate, and the electrical charge collecting electrodes
are formed on the opposing substrate. Further, when a resin material of
the space keeping members is soft, reinforcing members, which have
electrical insulation and are hardly deformed in a thermocompression
bonding, are dispersed into the resin material, so that the space keeping
ability is fully exhibited. According to this arrangement, it is possible
to improve the responsivity so as to respond to a moving image.
Additionally, an even space can be achieved between the substrates, and it
is possible to prevent a connecting defect and a defect caused by a leak
between the substrates.
