LIGHT SOURCE UNIT, LIGHTING DEVICE, AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide light source units capable of easily coupling each other by the arbitrary number and capable of reducing a risk of a damage at coupling parts.SOLUTION: A light source unit 20 includes a light source part 25a, a light source substrate 21, an electrode terminal part 27b protruded from the light source substrate 21, and an electrode terminal part 27a to be coupled with the electrode terminal part 27b as the latter is inserted on an inner side of the light source substrate.
