Abstract
Provided is a digitizer function-equipped liquid crystal display device capable of preventing the wire shadows of a loop antenna from being projected on a liquid crystal panel and capable of being applied to a large size liquid crystal panel. It is also possible to provide an information processing electronic device and a game device provided with the digitizer function-equipped liquid crystal display device. Here, the digitizer function-equipped liquid crystal display device includes: a liquid crystal panel 1; a light diffusion member 2 which is disposed between the liquid crystal panel 1 and a backlight 5 irradiating the liquid crystal panel 1 with light; an electromagnetic induction type loop antenna which is disposed at a portion apart from the light diffusion member 2 in the direction toward the backlight 5 by a predetermined spacing so as to detect a position on the plane of the liquid crystal panel 1 in one coordinate axis direction and another coordinate axis direction that intersects the one coordinate axis direction; and a spacing retaining means for retaining the spacing between the light diffusion member 2 and loop antenna at a predetermined spacing value. As the spacing retaining means, a first light transmitting member 3 formed of a plate material having a light transmitting property is used.
