ABSTRACT:
A spread illuminating apparatus includes: at least one light source; a light conductive plate which has the at least one light source disposed at one end surface thereof, and which allows light emitted from the at least one light source and introduced therein to exit out therefrom through both major surfaces thereof toward first and second liquid crystal display elements disposed respectively over the both major surfaces of the light conductive plate, wherein the second liquid crystal display element has a smaller display screen size than the first liquid crystal display element; and a reflecting means which is disposed at the other major surface of the light conductive plate so as to cover at least areas not covered by the second liquid crystal display element, and which reflects light toward the first liquid crystal display element.
