Zusammenfassung:	There is provided a display device having a superbly low power consumption, and a driving method for the same, as well as an instrument panel and an automotive vehicle having such a display device. A display device according to the present invention includes: an illuminator; a display panel for performing displaying by using light which is emitted from the illuminator; and a control circuit for controlling the illuminator. The illuminator includes a plurality of light source blocks, at least one light source belonging to each of the plurality of light source blocks. A displaying region of the display panel has a plurality of regions each performing displaying by using light which is emitted from a respective one of the light source blocks. The control circuit detects a level of a display signal which is input to each of the plurality of regions, and is capable of controlling a luminance of the respective light source block in accordance with the detected level of the display signal.
