Abstract: According to one embodiment, a method of driving a phased array antenna, includes applying voltages to phase control electrodes in a first period such that radio waves to be emitted from antennas are in a same phase in a first emission direction, and applying the voltages to the phase control electrodes in a second period such that the radio waves to be emitted from the antennas are held in the same phase in the first emission direction. An absolute value of the voltage applied in the second period is different from an absolute value of the voltage applied in the first period, in each of the phase control electrodes.

Abstract: There is provided a liquid crystal display device that reduces viewing angle color mixture on a high definition screen. In the liquid crystal display device, a pixel electrode is formed on a region surrounded by scanning lines and picture signal lines. The scanning line is insulated from the picture signal line by a first insulating film. An organic insulating film is formed to cover the picture signal line. The organic insulating film is not formed below the pixel electrode. A common electrode is formed to cover the organic insulating film and the first insulating film. A second insulating film is formed to cover the common electrode. The pixel electrode is formed on the second insulating film. On the organic insulating film, a metal light shielding film is formed as extending in a second direction. The metal light shielding film is in contact with the common electrode.
