Abstract

PURPOSE:To align light axes in a specified direction and remove luminance unevenness, by arranging a light emitting diode chip directly on a substrate and forming a condenser lens for each light emitting diode chip integrally to disposed it on the substrate. CONSTITUTION:A light emitting diode chip 17 is directly disposed on a substrate 11, condenser members 25 to which condenser lenses 26 are integrally formed are arranged on the substrates 11 via spacers 23 at intervals and opposed to each other. Therefore, the positional relation between a light emitting diode chip 17 and lens 26 and the optical axis direction of a lens 26 are uniquely defined and there is no possibility of variations in mounting. Thus, a device having each lens 26 aligned accurately in one direction can be made with high yield rate and accordingly it can be made efficiently without luminance variations.
