도 4a 내지 도 4d에 도시한 바와 같이, 본 발명에서는 액정표시패널을 고정하기 위한 패널가이드를 적어도 2개 이상 분할된 구조로 분리 형성하였다.As shown in FIGS. 4A to 4D, the panel guides for fixing the liquid crystal display panel are separately formed in at least two divided structures.

도 4a 및 도 4c와 같이, 상측부 제 1 패널가이드와 하측부 제 2 패널가이드로 분리하거나, 도 4b 및 도 4d에 도시한 바와 같이, 3개 또는 4개의 분할 구조로 패널가이드를 분할 형성하였다.As shown in FIGS. 4A and 4C, the panel guide is divided into upper and lower panel guides and lower panel guides, or divided into three or four divided structures as shown in FIGS. 4B and 4D. .

따라서, 본 발명에서는 액정표시패널이 종래 기술에서와 같이 패널가이드의 상측에서 놓이는 체결 방식이 아니라, 분할된 패널가이드의 내측을 따라 형성된 집게 형태("ㄷ")의 지지부와 고정부에 슬라이드 방식으로 삽입된 후 체결된다.Therefore, in the present invention, the liquid crystal display panel is not a fastening method which is placed on the upper side of the panel guide as in the prior art, but a sliding method on the support part and the fixing part of the tongs ("ㄷ") formed along the inside of the divided panel guide. It is fastened after being inserted.

즉, 분할된 패널가이드들의 고정부와 지지부 사이에 액정표시패널의 가장자리 영역이 삽입되어 조립된다.In other words, an edge region of the liquid crystal display panel is inserted between the fixing part and the supporting part of the divided panel guides.

도 5는 본 발명의 실시예에 따른 패널가이드와 액정표시패널이 체결된 모습을 도시한 평면도이고, 도 6은 본 발명의 다른 실시예에 따른 패널가이드와 액정표시패널이 체결된 모습을 도시한 평면도이다.5 is a plan view showing a panel guide and a liquid crystal display panel fastened according to an embodiment of the present invention, Figure 6 is a panel guide and a liquid crystal display panel fastened according to another embodiment of the present invention Top view.

도 5에 도시된 바와 같이, 본 발명은, 분할 구조를 갖는 패널가이드(100)의 내측 둘레를 따라 소정의 간격으로 고정부(101)들이 다수개 형성되어 있다. 또한, 도면에는 도시되지 않았지만, 고정부(101)와 대향하는 하측에는 고정부와 쌍을 이루도록 지지부가 형성되어 있다. 따라서, 액정표시패널(120)은 고정부(101)와 지지부 사이에 슬라이드 방식으로 삽입되어 고정된다.(구체적인 도면은 도 7을 참조한다)As shown in FIG. 5, in the present invention, a plurality of fixing parts 101 are formed at predetermined intervals along an inner circumference of the panel guide 100 having a split structure. In addition, although not shown in the figure, a support portion is formed on the lower side facing the fixing portion 101 so as to be paired with the fixing portion. Accordingly, the liquid crystal display panel 120 is inserted and fixed in a sliding manner between the fixing portion 101 and the supporting portion. (Refer to FIG. 7 for details.)

따라서, 본 발명의 고정부(101)와 지지부는 집게 형태로 형성되기 때문에 상기 고정부(101)는 액정표시패널(120)이 패널가이드(100) 상측 방향으로 분리되지 않도록 고정하는 역할을 한다. 즉, 본 발명의 패널가이드(100)에 형성된 고정부(101)와 지지부는 액정표시패널(120)을 백라이트 유닛 상부에 위치시키면서, 상측 방향으로 분리되는 것을 방지한다.Therefore, since the fixing part 101 and the supporting part of the present invention are formed in the shape of tongs, the fixing part 101 serves to fix the liquid crystal display panel 120 such that the liquid crystal display panel 120 is not separated in the upper direction of the panel guide 100. That is, the fixing part 101 and the support part formed in the panel guide 100 of the present invention prevent the separation of the liquid crystal display panel 120 in the upward direction while placing the liquid crystal display panel 120 on the upper part of the backlight unit.

따라서, 상기 패널가이드(100)에 형성된 지지부(도 7 참조)는 종래 패널가이드의 안착부 역할을 하고, 고정부(101)는 종래 상부커버 기능을 담당한다.Therefore, the support portion (see FIG. 7) formed in the panel guide 100 serves as a seating portion of the conventional panel guide, and the fixing portion 101 serves as a conventional upper cover function.

그러므로 본 발명의 분할 구조형 패널가이드(100)를 사용하면, 별도의 상부커버가 불필요하다.Therefore, when using the divided structural panel guide 100 of the present invention, a separate top cover is unnecessary.

도 6을 참조하면, 본 발명의 다른 실시예로써, 패널가이드(300)의 내측 둘레를 따라 연속하여 고정부(301)가 형성되어 있고, 상기 고정부(301)와 대응되는 하측에는 지지부(미도시)가 형성되어 있다. 상기 지지부도 고정부(301)와 동일하게 연속하여 패널가이드(300)의 내측 둘레에 형성된다.Referring to FIG. 6, according to another embodiment of the present invention, a fixing part 301 is formed continuously along the inner circumference of the panel guide 300, and a support part (not shown) is provided below the fixing part 301. O) is formed. The support part is also formed in the inner circumference of the panel guide 300 continuously in the same manner as the fixing part 301.

즉, 도 5의 패널가이드와 달리, 고정부(301)와 지지부(미도시)가 "ㄷ" 형태로 패널가이드 내측 둘레를 따라 연속적으로 형성되고, 상기 고정부(301)와 지지부 사이에 액정표시패널(120)의 가장자리 영역이 삽입된다. 점선으로 도시된 부분이 액정표시패널(120)의 가장자리 영역을 나타낸 것이다.That is, unlike the panel guide of FIG. 5, the fixing part 301 and the supporting part (not shown) are continuously formed along the inner circumference of the panel guide in the form of "c", and the liquid crystal display is provided between the fixing part 301 and the supporting part. The edge region of the panel 120 is inserted. The part shown by the dotted line shows the edge area of the liquid crystal display panel 120.

이와 같이, 본 발명은 액정표시패널(120)을 고정하기 위한 패널가이드를 다수개로 분할하여, 액정표시패널(120)의 조립성을 개선하였다. As described above, the present invention improves the assemblability of the liquid crystal display panel 120 by dividing the panel guide for fixing the liquid crystal display panel 120 into a plurality.

또한, 분할된 패널가이드의 내측을 따라 고정부와 지지부가 서로 쌍을 이루어 액정표시패널(120)을 상하측에서 고정하기 때문에 상부커버 없이도 액정표시패널(120)을 견고하게 고정할 수 있다.In addition, since the fixing part and the support part are paired with each other along the inner side of the divided panel guide to fix the liquid crystal display panel 120 from above and below, the liquid crystal display panel 120 can be firmly fixed without the upper cover.

따라서, 본 발명에서는 상부 커버 없이 패널가이드와 하부커버의 조립만으로 액정표시장치의 조립 공정을 완료할 수 있다.
Therefore, in the present invention, the assembly process of the liquid crystal display device can be completed only by assembling the panel guide and the lower cover without the upper cover.
