    • A liquid crystal display device 1 of the invention has a liquid crystal display panel in which a liquid crystal layer 14 is provided between a TFT substrate 2 and a CF substrate 25 that has a common electrode 26, a light sensing component LS1 with a TFT photosensor that senses external light, and an illuminating means controlled according to the output of the light sensing component. The light sensing component is deployed at the periphery of the TFT substrate's display area DA and uses a thin film transistor as photosensor. A capacitor C is connected between source and drain electrodes SL, DL for such TFT photosensor. One of the capacitor's terminals is connected to a standard voltage source VS via a switch element SW, and the other to the common electrode 26. Voltage that is always lower than the voltage applied to the common electrode by an amount corresponding to a reverse bias voltage is applied to the gate electrode GL for the TFT photosensor. The capacitor's voltage a certain time after the switch element turns off is output. As a result, it will be possible to provide a liquid crystal display device in which the light sensing component incorporated in the liquid crystal display panel is not susceptible to the influence of the drive signals for the display panel, and in which the light sensing component does not induce deterioration of the liquid crystals.

    • When a wastegate valve, which opens and closes an exhaust bypass passage bypassing an exhaust turbine, is open, exhaust gases of respective cylinders bypass the exhaust turbine and pass a sensing point of an air-fuel ratio sensor downstream of the exhaust turbine. Accordingly, the exhaust gases of the respective cylinders can be avoided from being mixed by the exhaust turbine, so an influence of an inter-cylinder variation in an air-fuel ratio due to an inter-cylinder imbalance abnormality becomes apt to appear in an output waveform of the air-fuel ratio sensor. Therefore, existence or nonexistence of the inter-cylinder imbalance abnormality is determined based on the output of the air-fuel ratio sensor when the wastegate valve is open. Eventually, the existence or nonexistence of the inter-cylinder imbalance abnormality can be determined accurately, thereby improving detection accuracy of the inter-cylinder imbalance abnormality.
    • 当打开和关闭旁路排气涡轮机的排气旁通通道的废气门打开时,各个气缸的废气旁路排气涡轮并将排气涡轮下游的空燃比传感器的感测点通过。 因此,可以避免各气缸的排气被排气涡轮混合,因此,由于气缸内不平衡异常引起的气缸内的变化对空燃比的影响容易出现在输出 空燃比传感器的波形。 因此,当排气门阀打开时,基于空燃比传感器的输出来确定气缸间不平衡异常的存在或不存在。 最终,可以精确地确定气缸内不平衡异常的存在或不存在,从而提高气缸间不平衡异常的检测精度。
