Abstract: Switching TFTs are controlled to a conducting state and a switching TFT to a non-conducting state, to provide a potential according to a threshold voltage to a gate terminal of a driving TFT. Then, in at least one embodiment, with the TFT maintaining the conducting state, a potential of a data line Sj is changed from a reference potential Vpc to a data potential Vdata to place the TFT in a conducting state. At this time, a current Ia flows and thus the gate terminal potential of the TFT rises. The higher the mobility of the TFT, the larger the amount of change in gate terminal potential and the smaller the current flowing through an organic EL element upon light emission. By this, a current that is not affected by variations in the threshold voltage of the TFT nor by variations in the mobility of the TFT flows through the organic EL element. Thus, in a current-driven type display device, variations in both the threshold voltage and mobility of a drive element are compensated for.

Abstract: Providing an end mill for reducing the use of the cutting fluid to prevent the environmental pollution. Because the end mill 1 includes the openings 5a which open along spiral grooves 4, and the openings 5a communicate with the aperture on the rear end surface of the shank 2 via the intake path 5, the chips generated in the cutting are aspirated forcibly from the openings 5a when air intake is performed via the intake path 5, and the aspirated chips can be discharged from the aperture on the rear end surface of the shank 2. As a result, because the use of cutting fluid for discharging the chips can be reduced (or unnecessary) in comparison with conventional products, environmental pollution can be prevented.

Moreover, as the chips are forcibly aspirated from the opening and discharged through the intake hole, the chips are not scattered around a workpiece under the cutting process and cleaning the chips can become simple and easy.
