Claim:
An electro-optical display device comprising: an electro-optical panel; a point light source; a light guide plate with a narrow end disposed adjacent to the point light source and a broader surface facing the electro-optical panel, the light guide plate receiving light radiated from the point light source at the narrow end and guiding the received light toward the electro-optical panel from the broader surface; a metal plate radiator having a substantial sheet shape, the metal plate radiator having a first broad surface, a second broad surface facing in the opposite direction than the first broad surface, and at least one side surface extending between the first and second broad surfaces, the first and second broad surfaces each being larger than the side surface, the second broad surface being at least partially exposed; and an adhesive layer that attaches the first broad surface of the metal plate radiator directly to the light point light source; wherein the first broad surface of the metal plate radiator is in contact with the light guide plate adjacent to the point light source.
