Document Type and Number:
Japanese Patent JP5128664
Kind Code:
B2
Abstract:
A liquid crystal display device (100) of the present invention includes: a liquid crystal panel (20) including: an active matrix substrate (21); a counter substrate (22); and a liquid crystal layer (23) provided between the active matrix substrate (21) and the counter substrate (22); and a backlight (10) illuminating the liquid crystal panel. The liquid crystal display device (100) has an area sensor function for detecting an external input position, and further includes a reflectance changing section (50) that reduces a reflectance of light from the backlight (10) in response to application of pressure on a panel surface (100a). The reflectance changing section (50) is configured so that in a state where no pressure is applied on the panel surface (100a), an air layer (50c) is formed between two elastic films (50a and 50b) whereas in a state where pressure is applied on the panel surface (100a), the two elastic films (50a and 50b) contact each other.
