LIGHT SOURCE MODULE, AND ELECTRONIC APPARATUS PROVIDED WITH SAME

摘要

A backlight module (10A) is provided with a substrate (20), an LED (30), a light-transmissive resin sealing part (33), and a light guide plate (40). The light-transmissive resin sealing part (33) seals the LED (30) mounted on the substrate (20) and has a convex lens surface. An annular groove part (43) functioning as a light diffusion part and a first concave part (41) having a concave lens surface are disposed on the first main surface (40a) of the light guide plate (40). A second concave part (42) having a roughly conically-shaped concave surface is disposed on the second main surface (40b) of the light guide plate (40) on a section facing the first concave part (41). The light-transmissive resin sealing part (33) and the light guide plate (40) are attached to one another by means of a light-transmissive adhesion layer (35) disposed between the aforementioned convex lens surface and the aforementioned concave lens surface.
