Fractional frequency division is performed by sequentially selecting phase signals for division, where transitioning from a previous phase signal to a next phase signal for division occurs in response to not only the frequency-divided previous phase signal but also a second one of the phase signals. In each circuit of pixels constituting a pixel unit, a transistor for providing an initialization voltage is arranged so that leakage current is reduced when the transistor is turned off. An axis of the tangential drive coil is aligned parallel to a surface of the component.
