摘要： There is provided a spread illuminating apparatus including an LED, a light guide plate and a flexible printed circuit board on which the LED is mounted, wherein the light guide plate includes: a light entrance end surface at which the light source is disposed; a light emitting portion from which light emitted from the light source and introduced into the light guide plate exits out in a spread manner; a slope portion which is disposed between the light entrance end surface and the light emitting portion and which has a thickness decreasing toward the light emitting portion; and a seat block disposed at the slope portion and configured to fixedly receive the flexible printed circuit board. In the spread illuminating apparatus, the length of the slope portion is substantially 1.78 times as large as the largest thickness of the slope portion.

摘要： A spread illuminating apparatus includes a point light source; a light guiding plate having a light incident face on which the point light source is mounted, and a light output face. The light incident face has light incident prisms diffusing light emitted from the point light source into a planar space substantially parallel with the light output face. The light incident prisms include: a first prism portion including a plurality of first prisms convex relative to the light incident face; and a second prism portion including a second prism convex relative to the light incident face, the second prism portion being placed next to the first prism portion in a longitudinal direction of the light incident face. The first prism partially overlaps another first prism adjacent thereto, and the vertex of each first prism is set higher than the vertex of the second prism relative to the light incident face.
