The object of the invention is to provide an FSC display apparatus that can easily achieve color balance. The display apparatus (1) according to the present invention, which includes a light source (30) for emitting a plurality of colored lights in sequence and in a repetitive manner and a display section (14) for controlling transmission or reflection of the lights emitted from the light source, produces a color display by dividing each field into a plurality of subfields and by causing a designated one of the plurality of colored lights to be emitted at least during a part of a period within the plurality of subfields thereby displaying on the display section an image corresponding to the designated colored light, wherein each of the subfields includes at least a data writing period for writing display data to the display section and a light-emission period for emitting the designated colored light, and the end timing of the light-emission period can be set in a variable manner.

The present invention suppresses the generation of a leak current that accompanies the polarity inversion of the voltage waveform of the opposing electrode. The display device that performs display by sequentially scanning a plurality of scan signal lines in a single cycle period comprises: a plurality of data signal lines that intersect the scan signal lines; a pixel electrode that is connected to the data signal lines; and an opposing electrode that is disposed opposite the pixel electrode and for which the polarity of an application voltage is inverted in each of the cycle periods. The cycle period includes a scan period in which one full scan of the scan signal lines is performed and a non-scan period in which the scan signal lines are not scanned. In the non-scan period, the absolute value across the gate and drain is held at or above a predetermined value and the decrease in a voltage difference between a pixel potential and a gate OFF potential caused by the polarity inversion of the application voltage to the opposing electrode is reduced. In a non-scan period, the polarity of the voltage applied to the opposing electrode is fixed at either polarity irrespective of the polarity inversion of the voltage of the opposing electrode in each cycle period.

In a valve seat made of an iron-based, composite sintered alloy having hard particles and a solid lubricant dispersed therein to have high wear resistance and good machinability, which is usable in high-power fuel direct injection engines with improved fuel efficiency and low emission, relatively coarse solid lubricant particles in such an amount as not to drastically reduce the strength of a sintered body are dispersed to provide self-lubrication, and as fine solid lubricant particles as not hindering the bonding of matrix particles are dispersed to improve machinability.

A valve seat of an iron-based sintered alloy having high wear resistance in a wide temperature range, which can be used in direct injection engines with improved fuel efficiency, low emission and high power, is obtained by limiting the amount of a solid lubricant dispersed in the matrix of the valve seat of an iron-based sintered alloy, and dispersing at least two types of hard particles having different hardnesses in the matrix, thereby providing high strength and self-lubrication, as well as improved wear resistance under no lubrication in a wide temperature range.
