Patent ID: 7479932

Claim:
A display device, comprising: a first display section which includes a plurality of gate signal lines; a plurality of source signal lines; first switching sections, each of which is disposed near each of crossings of the gate signal lines and the source signal lines with a control terminal for switching operation connected to the gate signal line; pixel electrodes, each of which is connected to the source signal line through the first switching section, the first display section further including a source-signal-line drive circuit for supplying a display data signal to each of the plurality of source signal lines; a second switching section; and a second display section which includes the plurality of gate signal lines; the plurality of source signal lines; the first switching sections; and the pixel electrodes, each of the source signal lines of the second display section being connected to a corresponding one of the source signal lines of the first display section through the second switching section, the second display section sharing the source-signal-line drive circuit with the first display section, the second switching section connects the corresponding source signal lines of the first display section to the source signal lines of the second display section and disconnects the corresponding source signal lines of the first display section from the source signal lines of the second display section based a switching control signal, the second display section being used for display less frequently than the first display section.
