Abstract
A planar light source device includes a planar fluorescent lamp and a luminance enhancing film. The planar fluorescent lamp includes first and second substrates, a sealing member and at least one partition member. The first substrate has a plate shape. The second substrate faces the first substrate. The second substrate includes light diffusing beads. The sealing member is disposed along edge portions of the first and second substrates to combine the first and second substrates. The at least one partition member is interposed between the first and second substrate to define discharge spaces. The luminance enhancing film is attached on an outer surface of the second substrate.
