Abstract
The invention provides a portable information terminal, such as a notebook PC, including light-emitting elements entirely having longer lives (a double-sided display panel having longer lives) and allowing lower power consumption with a double-sided display panel having a first screen on one surface of a substrate in the portable information terminal, such as a notebook PC, and a second screen on the other surface of the substrate on the opposite side of the first screen. In this case, light emission intensities and aperture ratios of the first and second screens may be differentiated for different applications of the first and second screens. One of the first screen and second screen may implement multi-color display, and the other may implement monochrome display. The double-sided display panel may be used in a lid of a portable information terminal, such as a notebook PC, and a touch-panel function may be provided thereto. Thus, a portable terminal such as PC can be manipulated easily even with the lid closed. Therefore, the portable terminal can be used easily even on the move.
