ABSTRACT:
A display device that performs display by illuminating an object having a display surface is reduced in size and improved in viewability. A panel-shaped illumination device is disposed facing a display surface of an instrument that is the illumination object. The illumination device has light-emitting regions patterned finely and facing the display surface of the instrument. A light-shielding layer is disposed on the light-emitting region of the illumination device on a side not facing the display surface of the instrument, that is, an observer-side. Illumination light emitted from the light-emitting region illuminates the display surface of the instrument uniformly and is reflected toward the observer before visually recognized through transparent region of the illumination device. At that time, direct visual recognition by the observer of the illumination light emitted from the light-emitting region is suppressed.
