摘要： Each light guide (21) has a fixed part (21b), formed at at least one side edge of a cross-section of the light guide (21) orthogonal to the length of the light guide (21), with which the light guide (21) is fixed to a chassis. The fixed part (21b) is thinner than the other side edge of the cross-section of the light guide (21) orthogonal to the length of the light guide (21) or a thick-walled part (21c) that is a central part of the cross-section of the light guide (21) orthogonal to the length of the light guide (21). Light scatterers (23) vary in density of arrangement between (i) a region where the light guide (21) varies in thickness between the thick-walled part (21c) and the fixed part (21b) and (ii) other regions along a direction orthogonal to the length of the light guide (21). Thus, the light guide (21) can be fixed via the fixed part (21b), and the influence on the optical characteristic by the provision of the thin-walled fixed part (21b) can be compensated for by providing the light scatterers (23) whose density of arrangement along the lateral direction has been adjusted.

摘要： According to a light source module of the present invention, a plurality of light guides (21) constituting a light guide plate are provided so as to extend, parallel with one another, in a long-side direction of the plurality of light guides (21) and so as to be separated from one another by gaps. Concavities and convexes are formed in an emission surface of each of the plurality of light guides (21) along the long-side direction of the plurality of light guides (21). Respective ridge lines of the convexes out of the concavities and convexes are substantially parallel with the long-side direction. With the arrangement, it is possible to provide (i) a light source module in which the rate of occurrence of luminance unevenness can be reduced and (ii) an electronic device including the light source module.
