Abstract
Disclosed is a liquid crystal display device that has a function of detecting the position where light emitted from an input pointer 50 has been inputted to an image display surface 10a of an display panel and that switches the display direction (vertical direction) of a display image on the display panel on the basis of the radiation direction of the light emitted from the input pointer 50. Thus, a display device having a position detection function that enables the display direction of a display image to be switched using a simple structure can be provided.
