Abstract
A liquid crystal display device () of the present invention includes: a liquid crystal panel () including: an active matrix substrate (); a counter substrate (); and a liquid crystal layer () provided between the active matrix substrate () and the counter substrate (); and a backlight () illuminating the liquid crystal panel. The liquid crystal display device () has an area sensor function for detecting an external input position, and further includes a reflectance changing section () that reduces a reflectance of light from the backlight () in response to application of pressure on a panel surface (). The reflectance changing section () is configured so that in a state where no pressure is applied on the panel surface (), an air layer () is formed between two elastic films (and) whereas in a state where pressure is applied on the panel surface (), the two elastic films (and) contact each other.
