Abstract: PURPOSE: An active matrix display device is provided to achieve the high-density integration of a pixel element by integrally using a high voltage power line with a signal selection line and excluding an additional signal line. CONSTITUTION: Two display circuits corresponding to the analog display mode and the digital display mode are disposed within one pixel element(200), while the two display circuits are adjacent to each other. One of two display circuits is selected through circuit selection circuits(40,43). Since a high voltage power line(150) of a retaining circuit(110) used under the digital display mode also performs as a signal selection line(88), the high-density integration of the pixel element is obtained. Further, the bias voltage(Vsc) supplied through a selection storage capacitor line is same as a signal(A). Therefore, the storage capacitor line is connected to the drain of a TFT(Thin Film Transistor)(122) of a signal selection unit(120), and a signal line for supplying the signal is omitted. Thus, the high-density integration of the pixel element is achieved.
