る、液晶表示装置。 A liquid crystal display panel supported almost vertically, a drive control circuit that drives the liquid crystal display panel to display a desired display, and a drive control circuit that detects when a person or object approaches an area in front of the liquid crystal display panel. Normally, the drive control circuit drives the liquid crystal display panel with a first drive voltage, but when the sensor detects the approach of a person or object, The drive control circuit drives the liquid crystal display panel with a second drive voltage based on the signal from the sensor, thereby changing the viewing angle of the liquid crystal display panel toward the front area. A liquid crystal display device.
