To provide a display device which hardly causes trouble even if an external mechanical force operate without lowering display picture quality when an external light antireflective layer for suppressing unwanted interfacial reflection is provided between a protection plate and a display panel.

The display device which has the display panel, the transparent protection plate on its front side, and a transparent layer between the display panel and protection plate is characterized in that a housing is separated and the protection plate can be slid and situated in the display device.
