A planar illumination apparatus comprising:
- a light-guiding plate that emits light made incident from a side face;
- a plurality of light sources that are arranged on the side face side and have respective light-emitting faces that emit light to be made incident on the side face;
- a substrate having a mounting face on which the light sources are mounted, the mounting face facing a face of the light sources opposite the light-emitting faces;
- and
- wiring that is formed on a face of the substrate opposite the mounting face and are connected to the light sources, wherein
- the wiring includes wiring extending from both ends of the light sources connected in series.
A substrate comprising:
- a mounting face on which a plurality of light source rows including a plurality of light sources connected in series are mounted while being arranged in a first direction;
- wiring that is formed on a face of the substrate opposite the mounting face and includes wiring extending from both ends of the light source rows;
- and
- at least one external connecting part that connects drive circuit that lights the light sources and the light sources;
- wherein
- the at least one external connecting part is provided for each of the light source rows or every two of the light source rows adjacent in the first direction so that wiring in one light source row does not overlap in a second direction crossing the first direction with wiring in another light source row.
