Display device and vehicle display device

Abstract

A display device is disclosed, comprising a panel module and a circuit board. The panel module includes a display surface defining a first region and a second region. The first region and the second region are adjacent along a fold line, and the second region is bent by the fold line such that the plane containing the first region and the plane containing the second region form an inclined angle. An image displayed in the first region and an image displayed in the second region are respectively projected onto separate first projection regions and second projection regions. The circuit board is electrically connected to the panel module and is disposed on the opposite side of the panel module relative to the display surface.
