ABSTRACT:
An object of the invention is to provide a display device that allows its useful life to be prolonged without letting the user of the device conscious of changes in the display state of the display device, and the power consumption to be prevented from increasing, and the usable time without charging to be prevented from being shortened even when a light emitting display device is used. The display device is driven by a power source chargeable by connection with an external power source and includes a display portion (4), a display control portion (31) that switches between an inverted display state and a non-inverted display state of said display portion (4), and a power source detection portion (5) that detects a connection with said external power source. The display control portion switches between the inverted display state and non-inverted display state of said display portion (4) when said power source detection portion (5) detects a connection with said external power source.
