Display element drive circuit and display apparatus

A display apparatus which displays image information, comprising:

• a display panel having:
• a plurality of scanning lines and a plurality of signal lines arranged to be orthogonal to each other;
• and a plurality of display pixels arranged in the vicinity of respective intersections of the respective scanning lines and signal lines,
• wherein each of the display pixels comprises a current control type display element and a display element drive circuit which controls a light emitting operation of the display element,
• a display element drive circuit comprising:
• an electric charge holding circuit which holds as a voltage component electric charges based on a gradation signal corresponding to display data;
• a write control circuit which supplies the gradation signal to the electric charge holding circuit at a timing of application of a selection signal;
• a plurality of current control type display elements;
• and
• a driving current control circuit which generates a driving current based on the voltage component held in the electric charge holding circuit and supplies the generated driving current to the display element,
• wherein at least one of the write control circuit and the driving current control circuit includes at least one field effect transistor,
• said at least one field effect transistor comprises a gate electrode, a source electrode and a drain electrode, and
• a source-side parasitic capacitance is formed between the gate electrode and the source electrode of said at least one field effect transistor and a drain-side parasitic capacitance is formed between the gate electrode and the drain electrode of said at least one field effect transistor, the source-side parasitic capacitance and the drain-side parasitic capacitance having different capacitance values.
