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; a light diffusion memberwhich is disposed between the liquid crystal paneland a backlightirradiating the liquid crystal panelwith light; an electromagnetic induction type loop antenna which is disposed at a portion apart from the light diffusion memberin the direction toward the backlightby a predetermined spacing so as to detect a position on the plane of the liquid crystal panelin 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 memberand loop antenna at a predetermined spacing value. As the spacing retaining means, a first light transmitting memberformed of a plate material having a light transmitting property is used.
