Abstract

A surface light source unit, a liquid crystal display apparatus, and a method for reducing snaking and vibration of the positive column caused in the surface light source unit are provided. The surface light source unit includes at least one discharge space for emitting light, a first electrode positioned a distance apart from the center of one side of the discharge space for emitting current, and a second electrode positioned at a distance apart from the center of the other side of the discharge space for receiving the current emitted from the first electrode. The first electrode and the second electrode disposed at both sides of the discharge space arranged on the upper side of the surface light source unit are positioned at the upper side of the center of the discharge space. The first electrode and the second electrode positioned at both sides of the discharge space arranged on the lower side of the surface light source unit are positioned apart from the center of the discharge space. Therefore, snaking and the vibration of the positive column are reduced. A black portion generated in the upper and lower side of the conventional surface light source unit is also reduced.

Description

technical field [0001] The invention relates to a surface light source unit, an electrode structure and a light emitting method of a liquid crystal display device having the surface light source unit. Background technique [0002] A liquid crystal display (LCD) is a flat panel display device that displays characters, images, and animations by controlling liquid crystals corresponding to data processed by an information processing device. [0003] The LCD device requires an additional light source unit because it is an element that cannot emit light by itself, unlike a display device having a self-luminous characteristic, such as a cathode ray tube. [0004] As the light source unit, light emitting diodes emitting one-dimensional light and cold cathode fluorescent lamps (CCFLs) emitting two-dimensional light are mainly used. However, since light emitting diodes and CCFLs have poor luminance uniformity, optical members such as diffusion sheets and prism sheets are required to...
