Abstract
A display device having a memory property capable of maintaining a displayed information even in a state of being separated away from a power source as a result of decreasing the effect of external noise. The display device is detachably attached to a control unit that includes a drive circuit and a power source for driving the display device. The display device has a memory property and maintains the displayed image even in a state of being detached from the control unit. An input protection portion which is an electric load such as resistor, IC or capacitor is provided for the input portion leading to matrix electrodes from the connection terminals for electrically connecting the display device to the control unit. This prevents the infiltration of noise through the connection terminals and lowers a change in the displayed image.
