Patent ID: 7220997

Claim:
A light receiving or light emitting device comprising: a plurality of particulate semiconductor elements disposed in at least one column; each semiconductor element of said plurality of elements having a light-to-electricity transducing function or an electricity-to-light transducing function; each semiconductor element in said at least one column including opposing end parts and a pair of opposing electrodes disposed on said opposing end parts; said pair of opposing electrodes interposing a center of each semiconductor between said pair of opposing electrodes; an axis between each pair of opposing electrodes being perpendicular to a longitudinal axis of said at least one column; said at least one column including flexible wires connecting in parallel each semiconductor element disposed in said at least one column; a space provided between adjacent semiconductor elements in said at least one column so that said at least one column is capable of being flexed; and a flexible covering material covering and embedding each semiconductor element and each wire in said at least one column.
