A female terminal includes a tubular portion which has a square tubular shape and receives a male terminal therein and a resilient member which is provided in the tubular portion so as to urge the male terminal toward an inner surface of the tubular portion. The resilient member includes a curved portion formed by a strip-like electrically-conductive metal sheet and a pair of mounting portions integrally formed respectively at widthwise-opposite side edges of the curved portion and extending away from each other. The tubular portion has a pair of side walls opposed to each other and has a pair of through windows provided on the side walls respectively, the pair of mounting portions being inserted in the pair of through windows respectively. At least part of each of the mounting portions located respectively in the through windows is greater in thickness than the other portion of each of the mounting portions.

It is the primary object of the present invention to provide a simple and accurate testing circuit and a testing method while occupying as small space as possible in an image display device. The testing circuit including a NAND circuit connected in series is mounted on the image display device. A broken wiring on a data signal line and a defect in a data latch circuit can be detected by observing an output waveform from the testing circuit. Accordingly, a broken wiring or the like on the data signal line and a scanning line and a defect in the latch circuit can be tested simply and accurately without an expensive testing apparatus and a great deal of time while occupying as small space as possible.

It is the object of the present invention to provide a simple and accurate testing circuit and a testing method while occupying as small space as possible in an image display device. By partly changing dummy pixels arranged in the periphery of a display region into a testing circuit, tests for detecting broken wires in data signal lines and scanning lines and whether pixels are controlled adequately can be conducted easily and accurately, occupying as small space as possible without a need of an additional complicated circuit. Accordingly, a display panel can be produced at a low cost.

It is an object of the present invention to solve a problem that malfunction of communication is generated by varying a frequency of a clock due to noise from outside in a case where there is no supplied signal in a circuit which performs negative feedback control so that the supplied signal and the feedback signal can maintain a fixed phase relationship between the signals. The present invention provides a configuration including a PLL circuit and an oscillator circuit, where a switch for switching an output between a signal from the PLL circuit and a signal from the oscillator circuit to the signal output portion is provided to switch from a connection to the PLL circuit to a connection to the oscillator circuit in a case where there is no received signal.

A PLL circuit includes a phase detector, a loop filter (LF), a voltage-controlled oscillator (VCO), and a frequency divider. The phase detector compares a phase of a signal Fs which is input from outside with a phase of a signal Fo/N which is input from the frequency divider. The loop filter generates a signal Vin by removing alternating current components from a signal input from the phase detector. The voltage-controlled oscillator outputs a signal Fo based on the signal Vin input from the loop filter. The frequency divider converts the signal Fo output from the voltage-controlled oscillator into Fo/N (frequency division by N), and outputs it to the phase detector.
