    摘要: In a small display system in which the area of each of a display device and a driving device is approximately reduced to the area of an image display part, the display device having the image display part and the driving device having a driving IC for driving the display device can be attached to or detached from each other. Display device-side electrode terminals connected to lines for driving individual display pixels of the display device are provided on the reverse surface of the display device opposite to the image display part. Driving device-side electrode terminals corresponding to the respective display device-side electrode terminals are provided on the display device connecting part of the driving device. When the display device is attached to the driving device, both the driving device-side electrode terminals and the display device-side electrode terminals are electrically connected so that an image can be displayed on the display device by the driving device.
