Claim:
A spread illuminating apparatus, comprising: a point-like light source; and a light guiding plate that includes: a light incident face to which the point-like light source direct; an emission surface being adapted to exit spread illuminated light that has been emitted from the point-like source and introduced through the light incident face; and a principal surface, wherein: a pair of light-direction changing inclined surfaces are arranged at the light incident face and provided between adjacent point-like light sources, the light-direction changing inclined surfaces being configured to each have an inclination starting from the emission surface and extending all the way to the principal surface that is facing the emission surface, and to narrow as moving toward a front of the light guiding plate, the light guiding plate has an inclined portion, the thickness of which decreases from a side of the light incident face to the front, and a base for fixing a flexible printed circuit board is formed on the inclined portion integrally formed on the light guiding plate, the base being formed in a region that does not include an area in front of the point-like source.
