In a surface emitting device in which a light source is bonded to a light guide bar in contact with a light guide plate, the light source is bonded to the light guide bar using an adjusting member for adjusting the position of the light source. Examples of the adjusting member include a spacer disposed under the light source, a recessed portion provided in a molded case, a positioning guide made by extending a reflective panel, and another positioning guide formed integrally with the light guide bar.
