Information processing apparatus including a main body and a lid body

An information processing apparatus having a main body and a lid body is configured so that the lid body can be switched between a closed state, a stacked state, a double screen state and an inverted state. Each of the main body and the lid body has a display section for displaying information and an input section composed of a transparent tablet and provided on the display section. As a sensor or the like detects the lid body in one of the four states, a control section of the information processing apparatus controls the display section so that a screen on the display section is appropriate to the detected state of the lid body. The control section also controls the lighting section for lighting the display section appropriately to the detected state of the lid body. This realizes appropriate display in accordance with usages of the information processing apparatus and offers an easy-to-operate and easy-to-use information processing apparatus. Besides, the lighting section is turned on/off according to needs, and therefore it is possible to prevent heat generation and to restrain power consumption.
