Abstract
Disclosed is a circuit constitution of a display apparatus comprising a digital memory (DM) cell for each pixel. The DM cell is composed of one inverter circuit, and a DM switching circuit for controlling an electrical conduction between a pixel electrode and the DM cell is provided. During a normal displaying period, the DM cell and the pixel electrode are not electrically conducted by the DM switching circuit, and a full-color image displaying is performed by dynamic image data supplied to a signal line. During a still image displaying, the DM cell and the pixel electrode are electrically conducted by the DM switching circuit, and a multi-color image displaying is performed by still image data retained in the DM cell.
