The color liquid crystal type electronic instrument panel is of the type that a plurality of plural-primary-color stripe filters are disposed on each segment of a display element in the longitudinal direction of the segment; a voltage is applied to electrodes corresponding to the stripe filters having a color selected based on the contents to be displayed, and the background light source is positioned at the back of the display element to enable color-displaying. A device for detecting the brightness of outdoor light is further provided in the liquid crystal display type electronic instrument panel, wherein the quantity of light to be radiated from the background light source is changed in accordance with a detected signal by the detecting device.
