Abstract
A surface light source device of a backlight unit for a liquid crystal display is provided. The surface light source device includes: a main body having a first panel, and a second panel between which an inner space is formed; and at least one partition wall for partitioning the inner space into a plurality of discharge spaces. The second panel includes a plurality of convex parts formed at the discharge spaces to be outwardly convex, and outermost convex parts have a larger outer curvature radius than other convex parts between the outermost convex parts.
Claims10
A surface light source device comprising:
- a main body having a first panel, and a second panel between which an inner space is formed;
- and
- at least one partition wall for partitioning the inner space into a plurality of discharge spaces,
- wherein the second panel includes a plurality of convex parts formed at the discharge spaces to be outwardly convex, and outermost convex parts have a larger outer curvature radius than other convex parts between the outermost convex parts.
A backlight unit comprising:
- a surface light source device including a main body having a first panel, and a second panel between which an inner space is formed, at least one partition wall for partitioning the inner space into a plurality of discharge spaces, and electrodes for applying a discharge voltage to the discharge spaces, wherein the second panel includes a plurality of convex parts formed at the discharge spaces to be outwardly convex, and outermost convex parts have a larger outer curvature radius than other convex parts between the outermost convex parts;
- a top case and a bottom case for housing the surface light source device;
- an optical sheet provided between the surface light source device and the top case;
- and
- an inverter for driving the surface light source device by supplying a discharge voltage to the electrodes.
