Patent ID: 7798654

Claim:
An image display apparatus comprising: a light source; a condensing mirror which condenses light emitted from the light source and makes 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 light reflected off the first mirror is incident, wherein each micromirror is turned to an ON state or an OFF state by individually changing the slope of the micromirrors and thus angles of reflection; and a projection lens which enlarges and projects light reflected from the micromirrors in the ON state, wherein the relay lens and the first mirror are disposed opposite to each other with respect to an optical axis of the projection lens interposed therebetween, and wherein the light tunnel has an exit end tilted at an angle relative to a line perpendicular to its central axis.
