Abstract
A micromirror device, which makes an image display with digital image data, comprises pixel elements each of which makes pulse width modulation (PWM) for incident light depending on the deflection state of light and which are arranged in the form of a matrix. Each of the pixel elements has a mirror, at least one memory cell comprising a transistor and a capacitor, and an electrode connected to each transistor. Memory cells arranged successively in a ROW direction are connected by a ROW line. The image data is loaded at a time interval during which the voltage of the electrode can hold the deflection state of a pixel element.
