ABSTRACT:
A plurality of LEDs are arrayed in a single row between the opposing end faces of a pair of first and second light guide plates that are disposed so that the end faces thereof face each other. A reflective sheet is disposed on the lower surfaces of the pair of first and second light guide plates, and a separation plate is disposed so as to cover the upper surfaces of the first and second light guide plates and the gap therebetween. A reflecting body for guiding light emitted upward from the LEDs to the first and second light guide plates is disposed in the area immediately above the LEDs on the lower surface of the separation plate. A diffusion plate is disposed with a fixed gap above the separation plate, and a hollow area is formed between the diffusion plate and the separation plate.
