ABSTRACT:
A rear projection monitor having a housing with reduced depth is disclosed. Images produced by liquid crystal active matrices are illuminated by a light source. The images are enlarged and projected by a projection lens having a large rear focus. A mirror reflects the projected images onto a viewing screen. The mirror is positioned between 36.degree. and 45.degree. in relation to the viewing screen. The back of the housing is adjacent to and slopes at the same angle as the mirror. The depth of the projection monitor is between 33% to 41% of the diameter of the viewing screen.
