Embodiment Construction

[0031] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0032] figure 1 is a partially cut perspective view showing a surface light source device according to an exemplary embodiment of the present invention. figure 2 is along figure 1 A cross-sectional view taken on the line A-A', image 3 is a magnified view showing figure 1 Part 'B' of .

[0033] see Figures 1 to 3 , the surface light source device 100 includes a lamp body 200 , a space dividing wall 300 , a discharge gas supply member 400 , and a voltage application member 500 .

[0034] The lamp body 200 includes a flat-shaped space and a fluorescent layer 260 .

[0035] Discharge gas is contained in the flat plate-shaped space. When a voltage is applied to the discharge gas, invisible light is generated. Thus, the phosphor layer 260 converts invisible light into visible light. The invisible light may be ultraviolet light.

[0036] The lamp body 200 ...

Abstract

A surface light source device includes a lamp body, a space dividing member, a discharge gas supplying member and a voltage applying part. The lamp body includes a flat shaped space and a fluorescent layer disposed in the flat shaped space to convert an invisible light into a visible light. The space dividing member divides the flat shaped space into a plurality of discharge spaces. The discharge gas supplying member is disposed to pass through the space dividing member and is fixed to the space dividing member, and supplies the discharge spaces with a discharge gas that generates the invisible light. The voltage applying part applies a discharge voltage to the discharge gas. Therefore, the lifetime of the surface light source device generating a planar light is increased, and the luminance of the light becomes uniform so that the display quality of an image is improved.

Description

technical field [0001] The present invention relates to a surface light source device, a method of manufacturing the surface light source device, and a liquid crystal display (LCD) device having the surface light source device. More particularly, the present invention relates to a surface light source device capable of improving lifespan and optical characteristics, a method of manufacturing the surface light source device, and an LCD device having the surface light source device. Background technique [0002] Generally, in a liquid crystal display (hereinafter referred to as LCD) device, the alignment of liquid crystal molecules changes in response to an electric field applied thereto, and thus their light transmittance changes. [0003] Conventional LCD devices display information including images by utilizing the liquid crystals. The LCD device has various advantages such as high luminance, high efficiency, uniform luminance, long life, thin thickness, light weight, and ...
