An in-finder display apparatus comprises: a finder optical system adapted to view an object image formed by a taking lens on a focal plane plate by means of an eyepiece lens through a penta roof prism, a display cell located on a display member disposed near an imaging plane for the object image, and an illuminating optical system for illuminating the display cell. The display cell is illuminated by the illuminating optical system so that light reflected off the display cell together with the object image is viewable via the finder optical system. The illuminating optical system comprises: a light emitting means, and a light projecting lens for converging a light beam leaving the light emitting means. The illuminating optical system is positioned such that an illuminating light beam leaving the light emitting means in the illuminating optical system enters the display cell after transmitting through the light projecting lens.
