Claim Text:
1. An illuminating device comprising: a plurality of light emitting elements constituting light emitting parts extending in a lengthwise direction; and a single light guide plate formed over the plurality of light emitting units having a first principal surface for emitting light originated from the light emitting elements as illuminating light and a second principal surface facing the first principal surface, the light guide plate having a plurality of light guide regions corresponding to the plurality of light emitting elements, wherein the plurality of light emitting elements are arranged to overlap with the light guide plate on a side of the second principal surface of the light guide plate in plan view, wherein the side of the second principal surface of the light guide plate is provided with wherein the first sectional surfaces and the second sectional surfaces extend in the lengthwise direction of the light emitting elements, and each light emitting part of the light emitting elements and each second sectional surface are disposed so as to overlap with each other in plan view, wherein the plurality of light emitting elements are disposed below the entire second sectional surface, wherein a plurality of first reflection layers are disposed on the second sectional surfaces and a plurality of second reflection layers are disposed under each of the plurality of light emitting units so as to overlap the light emitting elements in planar view, and wherein the first reflection layers and second reflection layers are formed opposite to each other with each of the corresponding light emitting elements being formed between a corresponding first reflection layer and second reflection layer.
