An uneven pattern detector has a structure wherein (a) detecting elements, each being provided with a TFT which is a switching element and a detecting electrode, are arranged in a matrix manner, and (b) a CSA connected to each data line detects charged or discharged electric charges at the respective detecting elements on respective rows sequentially selected by a gate line, whereby a capacitance (a coupled capacitance of Cf and Cx) reflecting fingerprint unevenness on a finger as a detection object can be detected. In the uneven pattern detector, each of the detecting elements is provided with an auxiliary capacitor electrode located so as to face the detecting electrode. This forms an auxiliary capacitor Cs between the auxiliary capacitor electrode and the detecting electrode. Further, a positive-phase input terminal of an operational amplifier of the CSA is connected with the auxiliary capacitor electrode so as to hold the positive-phase input terminal of the operational amplifier of the CSA and the auxiliary capacitor electrode at an identical potential. As a result, the electric charges can be detected by the CSA without being affected by the auxiliary capacitor Cs.

Uneven pattern detector and uneven pattern detecting method

A detector panel having a bias application electrode and a converter layer formed on a supporting substrate, and a readout panel (active matrix panel), are bonded to each other directly through a single layer of electroconductive resin. That is, a pattern of photosensitive resin is formed before-hand on reading electrodes of the readout panel, and this readout panel and the converter layer are bonded together directly. Since the converter layer has no pixel electrodes formed thereon, the converter layer need not be smoothed, and the two panels need not be positionally adjusted to each other with high precision.

On the interlayer insulating film, an upper layer insulating film is formed so as to cover the sense electrode. A surface of the interlayer insulating film in which surface the sense electrode is formed is flat. On this account, it is possible to provide an uneven pattern sensing device capable of smoothing out a surface thereof without any increase of the manufacturing process and limitation of a choice of materials for a protective film.

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.
