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.

An area sensor and an area-sensor-equipped display device are provided which can clearly discriminate between the presence and absence of a finger or input pen touching a panel surface. A liquid crystal display device (100) of the present invention includes: a liquid crystal panel (position detecting section) (20), provided with a plurality of light sensor elements (30) that detects the intensity of received light, which detects the position of an input through detection of an image on a panel surface (detector surface) (100a) by the light sensor elements (30); and a reflectance changing section (45), provided on that side of the liquid crystal panel (20) which faces the panel surface (100a), which effects a change in reflectance of light when pressure is applied to the panel surface (100a). The liquid crystal display device includes: an infrared light blocking filter (90) and an ultraviolet light blocking filter (40a), both provided on that side of the reflectance changing section (45) which faces the panel surface (100a), which do not transmit infrared light and ultraviolet light, respectively; and visible light blocking filters (31) provided on those respective sides of the light sensor elements (30) which face the panel surface (100a), which do not transmit visible light.

摘要:
A coordinate sensor (10) includes at least two line sensors (1) that are disposed in x-axis and y-axis directions, and right-angle prisms (2) each of which changes a light path of light that has passed through an image display region of a liquid crystal panel (20). Each of the line sensors (1) is disposed outside the image display region and has a light-receiving surface (1a) parallel to an image display surface of the liquid crystal panel (20). The right angle prisms (2) cause light which travels in the x-axis and y-axis directions and which has passed through the image display region to be guided to the light-receiving surfaces (1a) of the line sensors (1). The coordinate sensor (10) receives the light which has thus passed through the image display region of the liquid crystal panel (20) so as to detect a coordinate, on the image display region, that is indicated by an object to be detected such as a finger. Consequently, a thin coordinate sensor that enables easy alignment with no reduction in aperture ratio and no restriction on operation speed can be realized at low cost.
