An image reading apparatus for reading an image pattern of a detecting object comprises a detecting surface on which a detecting object is placed, a sensor array having a plurality of sensors arranged to read an image pattern of the detecting object placed on the detecting surface, a first detection electrode, provided on at least an upper portion of the sensor array, having the detecting surface; a second detection electrode provided to be electrically insulated and spaced from the first detection electrode; a counter electrode provided to be opposite to the first detection electrode through an interlayer insulating film; signal voltage applying circuit which applies a signal voltage having a first signal waveform that varies periodically to the counter electrode to excite a second signal waveform to the first detection electrode through the interlayer insulating film, and contact detector which determines whether the detecting object brought into contact with the detecting surface is a specific detecting object based on a third signal waveform excited to the second detection electrode according to contact of the detecting object with both the first detection electrode and the second electrode wherein a reading operation of the image pattern of the detecting object is performed based on the determination result by the contact detector.

Image reading apparatus and its driving method

In the present liquid crystal display device, a switching element, a data line connected to one end of the switching element, and an interconnecting wire insulated from the data line are formed on a substrate. The switching element, the data line, and the interconnecting wire are covered with an interlayer insulating film. An auxiliary capacitor electrode made of reflective metal and connected to the interconnecting wire is formed on the interlayer insulating film. An upper insulating film is formed on the interlayer insulating film to cover the auxiliary capacitor electrode, and a pixel electrode connected to the other end of the switching element is formed on the upper insulating film. The interconnecting wire is made of a material different from the auxiliary capacitor electrode, and the interlayer insulating film and upper insulating film have a contact hole which reaches the interconnecting wire.
