ク照明装置。[Scope of Claim for Utility Model Registration] A liquid crystal cell, a diffuser plate made of a translucent material disposed below the liquid crystal cell and whose lower surface is painted white, and a diffuser plate disposed below the liquid crystal cell that faces the end face of the diffuser plate. In a transmissive liquid crystal display device, a surface-mounted chip LED in which an LED chip is mounted on a substrate having a hole is used as the light source, and at least one end face of the diffuser plate is used as the light source. A boss extending substantially perpendicularly from the end surface of the diffuser plate is integrally planted near the light source mounting position,
By inserting the hole into the boss, the chip LED is positioned at a predetermined position with respect to the diffuser plate, and by caulking the boss, the chip LED is fixed to the end surface of the diffuser plate. A back lighting device for a liquid crystal display device, characterized by:
