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.

Abstract: In a spread illuminating apparatus comprising a spot-like light source, and a light conductive plate, the light conductive plate is shaped into a pentagon which has two sides thereof substantially parallel to each other. The pentagon includes, as a part thereof, a triangle having its base defined by an imaginary line connecting respective straightly opposing ends of the two parallel sides, and the spot-like light source is disposed at a side of the pentagon constituting one of two hypotenuses of the triangle.

Abstract: A touch panel has a reduced whole thickness when attached to a display device, increases the accuracy of the positional information, and improves the display quality and durability inexpensively. One of a pair of resistive layers facing each other across insulating dot spacers is laid on a light-transmissible flat plate formed of a PET film rather than a glass plate, and a light conductive plate of a front light unit is integrated with an outer surface of the light-transmissible flat plate. An AR film having a transparent gel layer is disposed between the PET film and the light conductive plate. The transparent gel layer is of a gel material such as silicone rubber and is applied integrally on the AR film, which is formed such that anti-reflection treatment is applied on a surface of a base material of a FET film.
