Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a liquid crystal display device which facilitates mounting of a long light source arranged along one side of a liquid crystal display panel.

[0002]

[Prior art]

 One type of conventional liquid crystal display device is a liquid crystal display device having a liquid crystal display panel and an elongated light source arranged along one side of the liquid crystal display panel. Although the display surface of the panel is illuminated, the fixing means for the elongated light source has the structure shown in FIG.

A long light source 1 shown in FIG. 1 is, for example, what is called a CFL tube (cold cathode tube), 2 is a cylindrical light emitting tube, and both ends thereof are rubber bodies 3 each having a rectangular parallelepiped shape. Has been inserted and fixed. As shown in FIG. 6, this rubber body 3 has different sides x, y, and z (for example, x> y> z), and one end of the cylindrical body 2 is for inserting the end portion of the cylindrical arc tube 2. 2 and a hole 6 into which a lead wire 5 for applying electric power to the cylindrical arc tube 2 is inserted.

A concrete connection structure between the rubber body 3 and the cylindrical arc tube 2 is as shown in FIGS. 7 is a plan view, FIG. 8 is a bottom view, FIG. 9 is a side view, and FIG. 10 is a sectional view taken along the section line XX shown in FIG. According to these drawings, the rubber body 3 is composed of a resin portion 3a and a rubber portion 3b, and such a combined structure has a cylindrical shape in which the lead wire 5 is first connected to the hole 4 of the rubber portion 3b. By inserting the arc tube 2 and then injecting a resin to solidify the resin, the lead wire 5 is fixed inside the resin portion 3a, and the resin portion 3a is also fixed to the rubber portion 3b.

Further, the cylindrical arc tube 2 having the rubber body 3 inserted at both ends is attached to a liquid crystal display panel fixing casing (not shown) of a predetermined shape, and the hole 6 of the rubber body 3 is further attached. The lead wire 5 extending from the hole 6 is connected to an inverter outside the liquid crystal display device in a fixed direction.

[0006]

[Problems to be solved by the device]

 However, according to the liquid crystal display device having the above-described configuration, since the sides x, y, z of the rubber body 3 are different, the arrangement direction of the rubber body 3 is determined, and moreover, the rubber body 3 is arranged. The surface on which the hole 6 is formed is also determined in relation to the direction in which the holes 3 are arranged, so that when the cylindrical arc tube 2 with the rubber bodies 3 inserted at both ends is attached to the liquid crystal display panel fixing casing. However, the degree of freedom in mounting the cylindrical arc tube 2 is remarkably reduced, and as a result, there is a problem in that the mounting workability is reduced.

[0007]

[Means for solving problems]

 The liquid crystal display device of the present invention includes a liquid crystal display panel, an elongated light source arranged along one side of the liquid crystal display panel, and a cubic rubber body for fixing both ends of the elongated light source. A housing for accommodating at least the elongated light source and a rubber body, and forming a hole for inserting an end portion of the elongated light source on at least two surfaces of the rubber body, and the two surfaces A hole for inserting a lead wire for applying power to the elongated light source is formed on the other surface.

【Example】

 An embodiment of the present invention will be described with reference to FIGS.

FIG. 1 is a plan view of a liquid crystal display device 7 of this embodiment. 8 is a liquid crystal display panel, 9 is a CFL tube, 10 is a rubber body for fixing the end portion of the CFL tube 9, and 11 is a rubber body 10. It is the lead wire that came out. FIG. 2 is a plan view of the CFL tube 9 having rubber bodies 10 attached to both ends, and FIG. 3 is a side view thereof. 4 is a cross-sectional view taken along the section line Y-Y in FIG.

As shown in these figures, the rubber body 10 has a rectangular parallelepiped shape in which the dimensions of each side are the same, and the ends of the CFL tube 9 are inserted into the two surfaces of this rubber body 10. Holes 12 and 13 are formed, and a hole 14 for taking out the lead wire 11 is formed on the other surface.

In the case of the rubber body 10 having the above-described configuration, the space area inside the housing of the liquid crystal display device 7 which is adapted to the rubber body 10 is already determined, but since it has a rectangular parallelepiped shape, the end portion of the CFL tube 9 is formed. Whichever of the holes 12 and 13 is inserted, it fits into the space area in the housing. Moreover, even if the end of the CFL tube 9 is inserted into either of the holes 12 and 13, it can be rotated by the central axis of the CFL tube 9, so the direction of the hole 14 for taking out the lead wire 11 is appropriately set. be able to.

In the liquid crystal display device 7 using the rubber body 10 having the above-described configuration, the rubber body 10 is inserted into both ends of the CFL tube 9 and the liquid crystal display panel is placed in the housing of the liquid crystal display device 7. 8 when the rubber body 10 is mounted on the liquid crystal display device 7 by inserting a rubber body 10 held by a worker involved in it into both ends of the CFL tube 9. In the process of mounting in the housing, the degree of freedom is increased and workability is further improved.

According to the above-mentioned embodiment, the rubber body 10 is formed with the holes 12 and 13 into which the ends of the CFL tube 9 are inserted, on two sides. Even if such a hole is formed, the same effect as the present invention can be obtained.

[0014]

[Effect of device]

 As described above, in the liquid crystal display device of the present invention, at least two surfaces of the rectangular parallelepiped rubber body for fixing both ends of the elongated light source are formed with holes for inserting the ends of the elongated light source, and at least By forming a hole for inserting a lead wire for applying power to the elongated light source on one surface, rubber bodies are inserted at both ends of the elongated light source and mounted in the housing of the liquid crystal display device. In doing so, the process of inserting the rubber body held by the worker involved in it into both ends of the elongated light source, and further installing the elongated light source with the rubber bodies inserted into both ends into the housing of the liquid crystal display device. In each process, the degree of freedom was increased, the workability was further improved, and as a result, the manufacturing efficiency was increased and the manufacturing cost was reduced.
