Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a planar light source device capable of mitigating luminance irregularity due to presence of a barrier rib; and a liquid crystal display device assembly. SOLUTION: This liquid crystal display device assembly is provided with: a transmission type liquid crystal display device 10 having a display region composed of pixels arranged in a two-dimensional matrix-like form; and this planar light source device 40 illuminating the liquid crystal display device 10 from the back. The planar light source device 40 comprises P×Q planar light source units 41 corresponding to P×Q display region units 12 when it is assumed the display region of the liquid crystal display device 10 is divided into the P×Q virtual display region units 12, and is characterized in that each planar light source unit 41 is isolated from another planar light source unit 41 by a plate-like barrier rib 43; and, when it is assumed that the height direction of the barrier rib 43 is a Z-direction, the cross section of the barrier rib is an undulating line shape when the liquid crystal display device 10 side of the barrier rib 43 is cut by a plane orthogonal to the Z-direction.
