Document Type and Number:
WIPO Patent Application WO2005040897
Kind Code:
A3
Abstract:
A surface light source apparatus (100) includes a main body (105) having a space, and a plurality of space division members (130) being disposed in the space so that the space division members (130) are extended in a first direction and arranged in a second direction spaced apart from one another to divide the space into a plurality of light emitting spaces (112). The space division members (130) include a plurality of connecting holes (132). At least two of the connecting holes (132) have different heights from one another with respect to a bottom surface of the main body (105) to have the light emitting spaces connected to one another through the connecting holes (132). The surface light source apparatus also includes a visible light emitting unit to generate a visible light in the light emitting spaces. Therefore, the brightness-uniformity of the surface light source apparatus and an image display quality of a display device are improved.
