Abstract

The surface light source (100) has a main body (200) including a first substrate (210), a second substrate (220) facing the first substrate, and a space dividing member (230). The first substrate (210) has a first fluorescent pattern (215) for converting invisible light into visible light. The first fluorescent patterns (215) are formed in parallel at first intervals (L1). The space dividing member (230) is disposed between the first and second substrates to form a discharge space (270). The width (W) of the space dividing member (230) is smaller than the first interval (L1) to emit the visible light between the space dividing member (230) and the first fluorescent pattern (215). The power supply member (300) generates the invisible light in the discharge space (270). Therefore, the surface light source (100) enhances the brightness of the visible light emitted from the subject.

Description

technical field [0001] The present invention relates to a surface light source, a method of manufacturing the surface light source, and a liquid crystal display (LCD) device having the surface light source. In particular, the present invention relates to a surface light source having enhanced luminance to improve image display quality, a method of manufacturing the surface light source, and an LCD device having the surface light source. Background technique [0002] In general, liquid crystals have electrical and optical properties. The alignment of the liquid crystal changes according to the direction of the electric field, thereby changing the transmittance index of the liquid crystal. [0003] A liquid crystal display device (LCD) displays images using electrical and optical properties of liquid crystals. LCD devices have advantages of light weight and small size compared with cathode ray tube type display devices, so that liquid crystal display devices are widely used ...
