There is provided a spread illuminating apparatus to ensure excellent light conductivity. A cover is integrally provided over a transparent substrate sandwiching a fluid (cushioning material) of a gel, liquid, or gaseous substance. With this structure, dust generated in assembly process is prohibited from getting on the transparent substrate, and even when other members or an assembly machine hit and bend the cover during the assembly process, the bending is absorbed by the fluid, and a light reflection pattern formed on the transparent substrate is protected against damages, whereby excellent light conductivity can be maintained.

1. A spread illuminating apparatus, comprising:a transparent substrate made of a light-transmissible material and having a light reflection pattern having a number of ridges formed on at least one surface thereof; and a bar-like light source disposed close to an end surface of the transparent substrate, wherein a cover formed of a light-transmissible material is integrally provided over the one surface of the transparent substrate sandwiching a cushioning material comprising a light-transmissible substance in such a manner that the number of ridges are directly covered with the cushioning material, the cushioning material is of a substance with low refractive index, and the substance is gel. 2. A spread illuminating apparatus, comprising:a transparent substrate made of a light-transmissible material and having a light reflection pattern having a number of ridges formed on at least one surface thereof; and a bar-like light source disposed close to an end surface of the transparent substrate, wherein a cover formed of a light-transmissible material is integrally provided over the one surface of the transparent substrate sandwiching a cushioning material comprising a light-transmissible substance in such a manner that the number of ridges are directly covered with the cushioning material, the cushioning material is of a substance with low refractive index and the substance is liquid. 3. A spread illuminating apparatus, comprising:a transparent substrate made of a light-transmissible material and having a light reflection pattern having a number of ridges formed on at least one surface thereof; and a bar-like light source disposed close to an end surface of the transparent substrate, wherein a cover formed of a light-transmissible material is integrally provided over the one surface of the transparent substrate sandwiching a cushioning material comprising a light-transmissible substance in such a manner that the number of ridges are directly covered with the cushioning material and the cushioning material is of a gaseous substance. 4. A spread illuminating apparatus, comprising:a transparent substrate made of a light-transmissible material and having a light reflection pattern having a number of ridges formed on at least one surface thereof; and a bar-like light source disposed close to an end surface of the transparent substrate, wherein a cover formed of a light-transmissible material is integrally provided over the one surface of the transparent substrate sandwiching a cushioning material comprising a light-transmissible substance in such a manner that the number of ridges are directly covered with the cushioning material, a thin film of a substance with low refractive index is formed on the light reflection pattern of the transparent substrate, and the cushioning material is of a gel substance. 5. A spread illuminating apparatus, comprising:a transparent substrate made of a light-transmissible material and having a light reflection pattern having a number of ridges formed on at least one surface thereof; and a bar-like light source disposed close to an end surface of the transparent substrate, wherein a cover formed of a light-transmissible material is integrally provided over the one surface of the transparent substrate sandwiching a cushioning material comprising a light-transmissible substance in such a manner that the number of ridges are directly covered with the cushioning material, a thin film of a substance with low refractive index is formed on the light reflection pattern of the transparent substrate, and the cushioning material is of a liquid substance. 6. A spread illuminating apparatus, comprising:a transparent substrate made of a light-transmissible material and having a light reflection pattern having a number of ridges formed on at least one surface thereof; and a bar-like light source disposed close to an end surface of the transparent substrate, wherein a cover formed of a light-transmissible material is integrally provided over the one surface of the transparent substrate sandwiching a cushioning material comprising a light-transmissible substance in such a manner that the number of ridges are directly covered with the cushioning material, a thin film of a substance with low refractive index is formed on the light reflection pattern of the transparent substrate, and the cushioning material is of a gaseous substance. 7. A spread illuminating apparatus, comprising:a transparent substrate made of a light-transmissible material and having a light reflection pattern having a number of ridges formed on at least one surface thereof; and a bar-like light source disposed close to an end surface of the transparent substrate, wherein a cover formed of a light-transmissible material is integrally provided over the one surface of the transparent substrate sandwiching a cushioning material comprising a light-transmissible substance in such a manner that the number of ridges are directly covered with the cushioning material, and the cushioning material comprises a plurality of transparent elastic members.
