Abstract
The purpose of the present invention is providing a light emitting module capable of emitting illumination light having a nearly uniform color tone as a whole. The invention also provides a surface light source having such light emitting modules, and a liquid crystal display and an illuminating device having such a surface light source. In a light emitting module (), adjacent dot light sources () satisfy the relationships ΔX+ΔX=ΔX×2 and ΔY+ΔY=ΔY×2, so that the resultant mixed color can fall within a target chromaticity rank area (M), and the center (gc) of a first chromaticity rank area g and the center (Ec) of a second chromaticity rank area (E) are axisymmetric with respect to virtual straight lines (gE, gE) that pass through the center (Mc) of the target chromaticity rank area (M) and parallel to one side or another side of the target chromaticity rank area (M).
