<p>PURPOSE:To enhance the sensor resolution capability by a method wherein a photodetecting element is provided on a substrate, a light-transmitting layer is formed on them, a light guidance section is provided capable of leading the light from the light-emitting section to a text reading section through the light-transmitting layer for the efficient guidance of the light from the light-emitting section to the text, and it is so arranged that the light reaching the photodetecting element will land on the text only. CONSTITUTION:A first light-screening layer 8 with a light receiving widow 2 and a light- guiding window 10 is provided on a first light-transmitting layer 4. Further, a second light- transmitting layer 3 and a second light-screening layer 9 are provided. In the second light- screening layer 9, there is a reading widow 11, which corresponds to the section to be read of a text 5. On the rear side of a glass substrate 6, there is a light-emitting layer 7 composed of an EL element or the like. In an image sensor designed as such, a photodetecting element 1 is built for example of amorphous silicon on a glass substrate 6, water glass is applied to be a light-transmitting layer 4 and then curing is accomplished. On the light-transmitting layer 4, a Cr light-screening layer 8 is deposited, and a light-receiving window 2 is provided by etching just on the photodetecting element 1. A process follows wherein glass is applied onto the light-screening layer 8 by spattering for the formation of a light-transmitting layer 3. Further, a light-screening layer 9 is formed for defining the text face.</p> |
