LIGHT SOURCE MODULE AND ELECTRONIC APPARATUS PROVIDED WITH SAME

摘要

In order to suppress the spreading of light in the perpendicular direction (lateral direction) to the linear advancing direction of light (longitudinal direction), a light source module is provided with: a light-guiding plate (20); LEDs (12) that cause light to enter at least one of the longitudinal-direction end surfaces of the light-guiding plate (20); and a group of microlenses (20b) for extracting the light guided through the interior of the light-guiding plate (20), said group of microlenses being arranged on the bottom surface (20c) that is opposite the light-emitting face (20d) of the light-guiding plate (20). The light source module also comprises a plurality of curved-surface structures (20a), which consist of curved-surfaces having ridges (20e) in the longitudinal direction thereof, on the light-emitting face (20d) of the light-guiding plate (20).
