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.

A planar light source device comprising:
- a planar fluorescent lamp having discharge spaces, the planar fluorescent lamp emitting light;
- and
- a luminance enhancing film attached to the planar fluorescent lamp.
A planar light source device comprising:
- a planar fluorescent lamp including a first substrate having a plate shape, a second substrate facing the first substrate, a sealing member disposed along edge portions of the first and second substrates to combine the first and second substrates, and at least one partition member interposed between the first and second substrates to form discharge spaces, the second substrate including light diffusing beads;
- and
- a luminance enhancing film attached to an outer surface of the second substrate.
A liquid crystal display (LCD) device comprising:
- a planar light source device including a planar fluorescent lamp having discharge spaces, and a luminance enhancing film attached to the planar fluorescent lamp, the planar fluorescent lamp emitting light;
- an LCD panel that displays images using the light;
