본 발명은 액정표시장치에 관한 것으로서, 보다 상세하게는, 광원을 지지하는 광원홀더와 하부샤시의 결합구조를 개선한 액정표시장치에 관한 것이다.The present invention relates to a liquid crystal display device, and more particularly, to a liquid crystal display device in which a coupling structure between a light source holder supporting a light source and a lower chassis is improved.

액정표시장치는 액정표시패널을 포함한다. 여기서, 액정표시패널은 박막트랜지스터 기판과 컬러필터 기판을 포함하며, 박막트랜지스터 기판과 컬러필터 기판 사이에는 액정층이 개재된다. 액정표시패널은 비발광소자이기 때문에 박막트랜지스터 기판의 후면에는 빛을 공급하기 위한 백라이트 유닛이 위치한다. 일반적으로 액정표시패널과 백라이트 유닛은 하부샤시에 수용되며, 하부샤시는 액정표시패널의 전면을 커버하는 상부샤시와 결합한다.The liquid crystal display device includes a liquid crystal display panel. The liquid crystal display panel includes a thin film transistor substrate and a color filter substrate, and a liquid crystal layer is interposed between the thin film transistor substrate and the color filter substrate. Since the liquid crystal display panel is a non-light emitting device, a backlight unit for supplying light is disposed on the rear surface of the thin film transistor substrate. In general, the liquid crystal display panel and the backlight unit are accommodated in the lower chassis, and the lower chassis is combined with the upper chassis covering the entire surface of the liquid crystal display panel.

한편, 백라이트 유닛은 램프와 같은 광원을 포함한다. 이러한 광원은 광원홀더에 지지되어 하부샤시에 수용된다. 이러한 종래의 광원홀더는 하부샤시에 접촉하는 하부에 돌출부가 형성되어 있다. 그리고, 하부샤시의 판면에는 광원홀더의 돌출부에 대응하여 결합부가 개구 형성되어 있다. 광원홀더와 하부샤시의 결합방법은 광원홀더의 돌출부를 하부샤시의 결합부에 삽입한다.On the other hand, the backlight unit includes a light source such as a lamp. This light source is supported by the light source holder and received in the lower chassis. In the conventional light source holder, a protrusion is formed at the bottom contacting the lower chassis. In addition, an opening is formed in the plate surface of the lower chassis to correspond to the protrusion of the light source holder. The coupling method of the light source holder and the lower chassis inserts the protrusion of the light source holder into the coupling portion of the lower chassis.

그러나, 이러한 종래의 광원홀더와 하부샤시의 구조는 결합력을 향상시키기 위해 돌출부가 결합부의 판면보다 더 돌출 형성되어 있고, 이에 따라 광원홀더와 하부샤시의 결합시 하부샤시의 외측으로 돌출부가 돌출되는 문제점이 있다. 또한, 하부샤시의 외측으로 돌출부가 돌출되어 있으므로, 외관의 수려함을 감소시키는 문제점이 있다.However, in the structure of the conventional light source holder and the lower chassis, the protrusion is formed to protrude more than the plate surface of the coupling portion in order to improve the coupling force, and thus the protrusion is protruded out of the lower chassis when the light source holder and the lower chassis are coupled. There is this. In addition, since the protrusion is protruded to the outside of the lower chassis, there is a problem of reducing the appearance of appearance.

따라서, 본 발명의 목적은, 광원을 지지하는 광원홀더와 하부샤시의 결합구 조를 개선한 액정표시장치를 제공하는 것이다.Accordingly, an object of the present invention is to provide a liquid crystal display device having improved coupling structure between a light source holder supporting a light source and a lower chassis.

한 쌍의 상기 홀더결합부가 상기 샤시본체의 상호 대향한 양 측벽에 한 쌍의 상호 대향 배치되는 광원홀더에 대응하여 배치되어 있을 수 있다.The pair of holder coupling portions may be disposed to correspond to a pair of light source holders disposed on opposite side walls of the chassis main body.

상기 광원홀더는 상기 하부샤시의 측벽에 밀착 지지되는 것을 그 특징으로 한다.The light source holder is characterized in that it is in close contact with the side wall of the lower chassis.

상기 광원의 양단부는 상호 대향 배치된 복수의 상기 광원홀더에 각각 지지되며, 상기 광원은 냉음극형광램프 및 외부전극형램프 중 어느 하나인 것을 그 특징으로 한다.Both ends of the light source are respectively supported by a plurality of light source holders disposed opposite to each other, and the light source is one of a cold cathode fluorescent lamp and an external electrode lamp.

In addition, the lower chassis 70 accommodates the above components, and the upper chassis 80 covers the entire surface of the liquid crystal display panel 10 corresponding to the lower chassis 70.

액정표시패널(10)은 박막트랜지스터가 형성되어 있는 박막트랜지스터 기판(11)과, 박막트랜지스터 기판(11)과 대면하고 있는 컬러필터 기판(12)과, 양 기판(11,12)을 접합시키며 셀갭(Cell Gap)을 형성하는 실런트(미도시)와, 양 기판(11,12)과 실런트 사이에 개재되는 액정층(미도시)을 포함한다. 액정표시패널(10)은 액정층의 배열을 조정하여 화면을 형성하지만 비발광소자이기 때문에 일측에는 구동신호를 인가하는 구동부(20)가 마련되어 있다.The liquid crystal display panel 10 bonds the thin film transistor substrate 11 on which the thin film transistor is formed, the color filter substrate 12 facing the thin film transistor substrate 11, and the two substrates 11 and 12 to form a cell gap. And a sealant (not shown) for forming a cell gap, and a liquid crystal layer (not shown) interposed between the substrates 11 and 12 and the sealant.
