Patent ID: 7238966

Claim:
A light receiving or light emitting panel, comprising: a plurality of granular semiconductor elements that have a light-to-electricity transducing function or electricity-to-light transducing function; a light transmitting printed wiring sheet comprising: a first flat surface; a plurality of retaining holes disposed in a form of a matrix having a plurality of rows and a plurality of columns, and printed wiring which is formed on said first flat surface; said semiconductor elements each comprising: an element main body made of a p type or n type semiconductor, a pn junction, and a pair of electrodes that are electrically connected to respective ends of the pn junction with a center of the element main body interposed between the electrodes; and the plurality of semiconductor elements being aligned in a common conductive direction and being respectively disposed and held in said retaining holes, the pair of electrodes of each semiconductor element being connected to said printed wiring; plural semiconductor elements, of said granular semiconductor elements, in each row or column parallel to said conductive direction being connected in series via said printed wiring; and plural semiconductor elements, of said granular semiconductor elements, in each column or row perpendicular to said conductive direction being connected in parallel via said printed wiring.
