There is provided a spread illuminating apparatus including a light guide plate, and an LED structure which is disposed at a side surface of the light guide plate, includes: a substrate having electrode patterns formed thereon; an LED chip disposed on the electrode patterns; and a light-transmittable resin adapted to seal up the LED chip and exposed due to a lamp house not provided therearound, and which has a longitudinal dimension substantially equal to the longitudinal dimension of the side surface of the light guide plate. The electrode patterns are formed so as to cover substantially the entire area of a surface of the substrate. Accordingly, heat generated by the LED chip can be efficiently transmitted and released outside, and also light introduced in the light guide plate is suppressed from leaking out from the side surface of the light guide plate.
