Abstract:
1. An image display device comprising: a display unit composed of plural pixels each having a light emitting means; a signal line for inputting an analog display signal to the pixels; and a light emitting drive means for driving the light emitting means based on the analog display signal inputted to the pixels through the signal line, wherein the light emitting drive means provided for each of the pixels is a field effect transistor, the signal line is connected to a gate of the field effect transistor through at least one capacitance means, one of a source or a drain of the field effect transistor is connected to a power supply means, the other of the source and the drain is connected to the light emitting means, and at least one of the source and the drain is connected via a first switch to the power supply means or the light emitting means, and the field effect transistor is constructed to apply one of the analog display signal and a virtually triangular pulse signal to the gate thereof through the capacitance means.
