Patent ID: 8319930

Claim:
A liquid-crystal display apparatus comprising: display pixels each located at an intersection of a scan line and a data line and each provided with a display-pixel switching device having a specific node connected to said data line and another node which is connected to said specific node to establish a conductive state of said display-pixel switching device when a select voltage is applied to said scan line, a display pixel electrode connected to said other node of said display-pixel switching device, and a liquid-crystal layer driven by a voltage appearing between said display pixel electrode and a common electrode; vision-angle control pixels each located at an intersection of said scan line and a vision-angle control line and each provided with a vision-angle control pixel switching device having a specific node connected to said vision-angle control line and another node which is connected to said specific node to establish a conductive state of said vision-angle control pixel switching device when a select voltage is applied to said scan line, a vision-angle control pixel electrode connected to said other node of said vision-angle control pixel switching device, and a transmittance exhibited for a vision angle to serve as a transmittance with a characteristic different from that of the transmittance of said display pixel or a reflectance exhibited for a vision angle to serve as a reflectance with a characteristic different from that of the reflectance of said display pixel; a scan-line driving circuit for sequentially selecting a scan line from a plurality of said scan lines in an order determined in advance and applying said select voltage to said selected scan line; and a vision-angle control circuit for supplying a vision-angle control signal set at a voltage corresponding to vision-angle control to said vision-angle control pixel connected to said selected scan line, to which said select voltage has been applied, through said vision-angle control line.
