Display device

A display device, comprising:

• a plurality of gate signal lines disposed in a predetermined direction on a substrate;
• a plurality of drain signal lines disposed in a direction different from the predetermined direction;
• a plurality of pixel elements which are disposed as a matrix, activated by a scanning signal fed through the gate signal line and provided with an image signal fed through the drain signal line;
• a first display circuit which has a storage capacitor element for holding an analog image signal fed through the drain signal line in response to a signal fed through the gate signal line and supplies the signal held by the storage capacitor element to a pixel electrode;
• a second display circuit which is disposed near the first display circuit, includes a retaining circuit holding a digital image signal fed through the drain signal line in response to the signal fed through the gate signal line and a signal selection circuit for selecting one of the signals fed through a first and second signal lines for supplying said one of the signals to the pixel electrode;
• and,
• a circuit selection circuit for selecting one of the first and second display circuit in response to a circuit selection signal;
• wherein one of the first and second signal lines works as a storage capacitor line for biasing an electrode of the storage capacitor element.
