Liquid crystal projection display device with mirror

A projection display device comprising:

• a source of light;
• a plurality of display elements receiving light from the source and capable of forming images, respectively;
• a plurality of projection lenses arranged in a row in a side by side relationship and having respective optical axes extending parallel to each other, the display elements and the projection lenses being arranged to form sets individually;
• and
• a mirror arranged between the display element and the projection lens of at least one of the sets so that the display element in said at least one set faces in a first direction and the display element in the adjacent set faces in a second direction different from the first direction;
• wherein the display element in said at least one set and the display element in the adjacent set are arranged such that a distance between the projection lenses of the adjacent sets is smaller than would otherwise be possible when a mirror is not arranged between the display element in an arrangement in which the projection lens of any adjacent sets and display elements face in the same direction.
