Abstract
A memory card having a liquid crystal display device is reduced in thickness. To this end, the back side of a liquid crystal display panel is provided with a white diffusing plate and the memory card is not provided with a light source for backlighting. A digital electronic still camera, into which the memory card is removably inserted, is provided with a light source for backlighting. When the memory card has been inserted into the digital camera, the transmission-type liquid crystal panel is illuminated using the light source of the camera. Thus an image displayed on the liquid crystal display device of the memory card can be viewed even though the memory card does not have a light source for backlighting.
