Abstract: An in-vehicle display device capable of reducing an impact applied to a vehicle body from a lateral direction is provided. The display device includes a rear bezel fixed to the vehicle body, a front bezel attached to the rear bezel, a frame including an outer edge portion attached to the front bezel, a display panel including an outer peripheral edge fixed to an inner peripheral edge of the frame, and a frame extension portion extending from the frame and disposed at least close to a side portion of the front bezel. The display panel is supported so as to be movable together with the frame with respect to the rear bezel by the frame extension portion being pressed by the side portion deformed due to an impact applied from a lateral side of the vehicle body.
