Problems solved by technology
[0005] However, the surface light source has a problem in that the luminance uniformity of the light near the end of each discharge space is significantly reduced compared to the central part of each discharge space.
A study of this problem reveals that current leakage between the surface light source and the metal-containing container leads to a reduction in brightness uniformity
This current leakage reduces the brightness uniformity of light in the LCD device, thereby deteriorating the display quality of the LCD device

Abstract
The present invention discloses a backlight assembly providing improved brightness uniformity and an LCD device having the same. The backlight assembly includes a flat fluorescent lamp and a receiving container. The receiving container has a bottom plate and side walls to accommodate the surface light source. The bottom plate includes an opening overlapping the outermost discharge space positioned along an edge of the flat fluorescent lamp. The opening is formed at a corner portion of the bottom plate and extends parallel to the discharge space of the lamp. The backlight assembly also includes a buffer member interposed between the flat fluorescent lamp and the receiving container to support the flat fluorescent lamp. The cushioning member includes a protruding portion capable of being coupled to the hole of the receiving container, so that the cushioning member is firmly fixed to the receiving container. The device reduces the current leakage of the surface light source, thereby improving brightness uniformity.
Description
technical field [0001] The present invention generally relates to a backlight assembly and a liquid crystal display (LCD) device having the same. More particularly, the present invention relates to a backlight assembly capable of improving brightness uniformity of light and a liquid crystal display device having the same. Background technique [0002] In general, LCD devices display images by using liquid crystal molecules. An LCD device is a type of flat panel display device that is becoming more and more popular. One of the reasons why LCD devices are becoming more and more popular is that LCD devices have various excellent characteristics such as thin thickness, light weight, low driving voltage requirement, low power consumption, and the like. Today, LCD devices are widely used in various industrial fields. [0003] An LCD device is a non-emissive display device, and thus it often uses a light source such as a backlight assembly. Hollow cylin...
