1. An Image display device comprising:
a display unit composed of plural pixels each having a light emitting element;
a signal line for inputting an analog display signal to the pixels; and
a light emitting drive element for driving the light emitting element based on the analog display signal inputted to the pixels through the signal line, wherein
the light emitting drive element provided for each of the pixels is a field effect transistor,
at least one of a source and a drain of the field effect transistor is connected to a switch element for defining the light-on and the light-off of the light emitting element,
the signal line is connected to the gate of the field effect transistor through one capacitance.
