Display device, cabin system and vehicle

The utility model provides a display device which can be applied to a cabin system and a vehicle. According to the display device provided by the invention, electrostatic isolation between the metal shell and the PCB of the display device can be realized, so that electrostatic protection on the PCB is achieved. The display device comprises a window unit, a first metal shell, an isolation component, a first module and a printed circuit board (PCB). The first metal shell is fixedly connected with the outer surface of the window unit, and the PCB is fixedly connected with the second surface of the isolation component. Wherein an open hole is formed in the outer surface of the first metal shell, an isolation component is arranged in the open hole, the first surface of the isolation component is fixedly connected with the inner surface of the first metal shell, and the first module is arranged on the first surface of the isolation component at the open hole. The isolation component is used for performing electrostatic protection on the PCB, the first module and the PCB realize one or more functions of the display device, and the window unit is used for watching images generated by the display device through the outer surface of the window unit by human eyes.
