摘要：PROBLEM TO BE SOLVED: To provide a display device that reduces consumption of DC current in a level conversion circuit and can achieve low power consumption as the whole device, and to provide a portable terminal device using the display device as an output display unit. SOLUTION: The display device is equipped with: a pixel unit 11 comprising pixel circuits including liquid crystal cells arrayed in a matrix; a vertical driving circuit 12 that selects and drives the pixel circuits of the pixel unit 11 by a row unit; a selector circuit 14 that selectively supplies image signals under drive control by a selector driving system to the pixels of a row selected and driven by the vertical driving circuit 12; and a level conversion circuit 15 that performs level conversion (level shift) of selector pulses for selecting and driving the selector circuit 14. The display device has a driving circuit-integrated configuration in which the vertical driving circuit 12, the selector circuit 14 and the level conversion circuit 15 are fabricated as integrated on a liquid crystal display panel 16.
