Suppresses the occurrence of contamination due to Therefore, it is possible to prevent the contamination of the liquid crystal when the liquid crystal is injected into the inner space of the liquid crystal panel 39, thereby reducing the occurrence of radial spots in the vicinity of the injection hole 41.

또한, 제 2 홈(36)은 액정패널(39) 내부 공간으로 액정을 주입할 때 액정쟁반(31)과 액정패널(39)의 접촉면을 따라 흐르는 액정의 흐름을 차단한다. 그러므로, 액정쟁반(31)과 액정패널(39)의 접촉면을 따라 흐르는 액정은 제 2 홈(36)의 내부에 고이게 되어 액정쟁반(31)의 몸체(33)를 따라 외부로 흐르는 것이 방지된다. 따라서, 액정쟁반(31)의 몸체(33)를 따라 외부로 흐르는 액정에 의해 액정플레이트와 주입챔버의 오염을 방지할 수 있다.In addition, the second groove 36 blocks the flow of liquid crystal flowing along the contact surface between the liquid crystal tray 31 and the liquid crystal panel 39 when the liquid crystal is injected into the liquid crystal panel 39. Therefore, the liquid crystal flowing along the contact surface of the liquid crystal tray 31 and the liquid crystal panel 39 is accumulated inside the second groove 36 and prevented from flowing out along the body 33 of the liquid crystal tray 31. Therefore, it is possible to prevent contamination of the liquid crystal plate and the injection chamber by the liquid crystal flowing out along the body 33 of the liquid crystal tray 31.

상술한 바와 같이, 본 발명에 따른 액정쟁반은 제 1 홈의 양측에 평행하게 형성된 제 2 홈에 의해 액정패널과의 접촉면적이 감소되므로 충격으로 인한 오염을 억제하여 주입구 부근에 방사형 얼룩이 발생되는 것을 감소시킬 수 있으며, 또한, 액정패널과의 접촉면을 따라 액정이 흐르는 것을 방지하여 액정플레이트와 주입챔버의 오염을 방지할 수 있는 잇점이 있다.As described above, in the liquid crystal tray according to the present invention, since the contact area with the liquid crystal panel is reduced by the second grooves formed parallel to both sides of the first groove, radial staining is generated near the injection hole by suppressing contamination due to impact. In addition, there is an advantage in that the liquid crystal can be prevented from flowing along the contact surface with the liquid crystal panel to prevent contamination of the liquid crystal plate and the injection chamber.
