ABSTRACT:
A display device in a view finder of a camera includes an illumination light source for illuminating the display portion and an illumination light leading body. The body has a reflecting surface and two permeable surfaces having such a refracting force such that the light emitting portion of the illumination light source is almost conjugate with the position of the pupil while observing the image in the view finder. The apparatus is arranged in such a manner that the illumination light beam is incident upon the one permeable surface of the illumination light leading body and goes out at the other permeable surface so as to illuminate the display portion. Accordingly, the display portion is observed together with the image in the view finder.
