<p>Provided is an image display apparatus with a slim design and improved illumination efficiency and which is able to suppress degradation of contrast thereby eliminating ghost. The image display apparatus includes: a light source; a condensing mirror condensing light emitted from the light source and making a virtual secondary light source; a light tunnel on which light passing through a color filter is incident; a relay lens system through which light exiting the light tunnel passes; a first mirror on which the light passing through the relay lens is directly or indirectly incident; a reflective display including a plurality of micromirrors arranged on a substrate in a matrix, on which the light reflected off the mirror is incident, wherein each micromirror is turned on or off by individually changing the slope of the micromirrors thus angles of reflection; and a projection lens enlarging and projecting light reflected from micromirrors in the on state, wherein the relay lens system and the mirror are disposed opposite to each other with an optical axis of the projection lens interposed therebetween.</p> |
