1. A solid-state image device, comprising: an image region which has a plurality of optical-electrical conversion portions two-dimensionally arranged and a plurality of vertical CCD registers which are placed adjacent to said optical-electrical conversion portions arranged in line in a vertical direction, said vertical CCD register transferring electrical charge signals converted by said optical-electrical conversion portions toward the vertical direction; a horizontal CCD register which is coupled to said vertical CCD registers at one end and which transfers the electrical charge signals toward a horizontal direction; a first light shielding film which covers said image region except for said optical-electrical conversion portions and which is formed by a first material; and a second light shielding film which covers said horizontal CCD register and which is formed by a second material; the first material being different from the second material. 2. A device as claimed in claim 1, wherein: said horizontal CCD register includes a plurality of charge transfer electrodes for transferring the electrical charge signals under said second light shielding film, and said second light shielding film is arranged so as to reduce parasitic capacitance with respect to said charge transfer electrode. 3. A device as claimed in claim 1, wherein: the first material comprises metal or metal silicide while the second material comprises resin. 4. A device as claimed in claim 1, wherein: said second light shielding film partially is overlapped with said first light shielding film. 5. A device as claimed in claim 4, wherein: said vertical CCD register comprises a final charge transfer electrode, and said second light shielding film is overlapped with said first light shielding film over said final charge transfer electrode. 6. A device claimed in claim 3, wherein: said horizontal CCD register has a flattening film over said charge transfer electrode, and said second light shielding film is formed between said flattening film and said charge transfer electrode. 7. A device claimed in claim 3, wherein: said horizontal CCD register has a flattening film over said charge transfer electrode, and said second light shielding film is formed on said flattening film. 8. A device claimed in claim 7, wherein: said first light shielding film has first light shielding performance while said second light shielding film has second light shielding performance, and the second light shielding performance is substantially equal to the first light shielding performance by adjusting a thickness of said second light shielding film. 9. A device as claimed in claim 1, wherein: said second light shielding film is formed by laminating a plurality of color filters. 10. A device as claimed in claim 9, wherein: said color filters are overlapped to each other at both ends. 11. A device as claimed in claim 9, wherein: said color filters are displaced from to each other at one end.
