Abstract: A planar illumination device according to an embodiment includes a light source, a circuit board and a pair of routing portions. The light source has a light emitting surface that emits light. The light source is mounted on the circuit board. A pair of land portions is provided on the circuit board, serves as a region where solder for electrically connecting respectively a pair of electrodes of the light source thereto is applied, is formed of an electrically conductive material, and corresponds to the electrodes. The pair of routing portions extends from each of the pair of land portions to at least a cover lay that protects a wiring on the circuit board and is formed of an electrically conductive material integrated with the land portions. First missing portions, being a region where the electrically conductive material is missing, are provided in each of the pair of routing portions.
