Abstract

A highly portable semiconductor device and the like providing improved browsability of display. Provided is a semiconductor device including a flexible display panel, a first housing supporting a first region of the display panel, a second housing supporting a second region of the display panel, and a flexible base material firmly attached to the first housing. The display panel can be deformed into an open position where the first and second regions are substantially on the same plane or into a folded position where the first and second regions overlap with each other. The second housing includes a groove portion where the flexible base material can partly slide. Part of the flexible base material is inserted into the groove portion in the open position. The part of the flexible base material which is inserted into the groove portion is at least partly withdrawn in a deformation into the folded position.
