<P>PROBLEM TO BE SOLVED: To provide a compact in-finder display apparatus that is used in a single-lens reflex camera including a penta roof prism or the like to produce superimposed displays, and prevents the camera from growing bulky. Ž<P>SOLUTION: The in-finder display apparatus includes: a finder optical system adapted to view an object image formed by a taking lens on a focal plane plate 31 by means of an eyepiece lens through a penta roof prism 37; a display part 32b located on a display member 32 disposed near an imaging plane for the object image; and an illuminating optical system 33 for illuminating the display part 32b. The display part 32b is illuminated by the illuminating optical system 33 so that light reflected off the display part 32b together with the object image is viewable via the finder optical system. The illuminating optical system 33 includes: a light emitting means 34, and a light projecting lens 35 for converging a light beam leaving the light emitting means 34. The illuminating optical system is positioned such that an illuminating light beam leaving the light emitting means 34 in the illuminating optical system 33 enters the display part 32b after transmitting through the light projecting lens 35.
