Liquid crystal display, illuminant module and its manufacturing method

An illuminant module comprising:

• light emitting elements;
• a substrate on which the light emitting elements are mounted;
• a transparent encapsulating resin which encapsulates the light emitting element;
• and
• a lens material having cavities formed therein, in which the respective light emitting elements and transparent encapsulating resin are stored, wherein:
• notches are formed in a surface of the lens material on the side of the substrate,
• the notch surfaces of the notches and the surface of the substrate are bonded using a bonding material, and
• the gap between a surface of the lens material and a surface of the substrate which are opposed to each other nearly in parallel with each other is devoid of the bonding material, and the mutually opposed surfaces are not attached to each other or are bonded using an adhesive whose adhesion is weaker than the bonding material.
