Surface light source device and liquid crystal display apparatus having the same

A surface light source device, comprising:

• a light source body having an internal space;
• a partition wall in the internal space to divide the internal space into a plurality of discharge spaces, the partition wall having end portions that make contact with inner surface of the light source body and a throughhole, through which the discharge spaces are connected to each other, the throughhole being disposed at a lower portion of the partition wall.

A liquid crystal display apparatus comprising:

• a surface light source device including a light source body that has an internal space, a partition wall disposed in the internal space to divide the internal space into a plurality of discharge spaces, the partition wall having end portions that make contact with inner surface of the light source body and a throughhole, through which the discharge spaces are connected to each other, the throughhole being disposed at a lower portion of the partition wall;
• and
• a liquid crystal display panel including liquid crystal to convert a light generated from the surface light source device into an image light.
