In addition, in the liquid crystal display module, light sheets for vertically raising light traveling from the backlight unit toward the liquid crystal panel are arranged. The liquid crystal panel, the backlight unit and the light sheet should be fastened in an integrated form to prevent light loss and should be protected from damage by external impact. To this end, a case for a liquid crystal display device formed to surround the backlight unit and the light sheets including the edge of the liquid crystal panel is provided.

Referring to FIG. 1, a conventional liquid crystal display module includes a support main 14, a backlight unit and a liquid crystal panel 6 stacked inside the support main 14, and an edge of the liquid crystal panel 6. It is provided with a case top (Case Top) (2) surrounding the support main 14 as well as wrapping.

The liquid crystal panel 6 includes a spacer (not shown) for injecting liquid crystal between the upper substrate 3 and the lower substrate 5 and for maintaining a constant gap between the upper substrate 3 and the lower substrate 5. . In the upper substrate 3 of the liquid crystal panel 6, a color filter, a common electrode, a black matrix, and the like, which are not shown, are formed. In addition, signal lines such as data lines and gate lines (not shown) are formed on the lower substrate 5 of the liquid crystal panel 6, and thin film transistors (“TFT”) are formed at the intersections of the data lines and the gate lines. Is formed. The TFT switches the data signal to be transmitted from the data line toward the liquid crystal cell in response to the scan signal (gate pulse) from the gate line. The pixel electrode is formed in the pixel region between the data line and the gate line. In addition, one side of the lower substrate 5 is formed with a pad region for connecting data lines and gate lines, respectively, and a tape carrier (not shown) in which a driver integrated circuit for applying a driving signal to a TFT is mounted on the pad region. The package (Tape Carrier Package) is attached. The tape carrier package supplies data signals and scan signals to the data lines and the gate lines from the driver integrated circuit, respectively.

The upper polarizing sheet 4a is attached to the upper substrate 3 of the liquid crystal panel 6, and the lower polarizing sheet 4b is attached to the rear surface of the lower substrate 5. At this time, the upper and lower polarizing sheets 4a and 4b are responsible for extending the viewing angle of the image displayed by the liquid crystal cell matrix.

The support main 14 is a mold, and the side wall surface thereof is formed into a stepped stepped surface. The innermost layer of the support main 14 is equipped with a backlight unit comprising a reflective sheet 12, a light guide plate 10 and a plurality of optical sheets 8 and a lamp housing not shown.

The case top 2 is manufactured in the form of a square strip having a flat portion and a side portion bent at a right angle. The case top 2 surrounds the edge of the liquid crystal panel 6 and the support main 14.

Light generated by the lamp is incident on the light guide plate 10 through an incident surface existing on the side of the light guide plate 10. The lamp housing reflects light from the lamp toward the incident surface of the light guide plate 10.

The reflective sheet 12 serves to reduce light loss by rereflecting light incident to itself through the rear surface of the light guide plate 10 toward the light guide plate 10. That is, when light from the lamp is incident on the light guide plate 10, the light propagated toward the lower surface and the side surface of the light guide plate 10 is reflected by the reflective sheet 12 and travels toward the front surface.

The plurality of optical sheets 8 generates light emitted from the light guide plate 10 vertically to improve light efficiency. To this end, diffusion sheets for diffusing the light emitted from the light guide plate 10 to the entire region and two prism sheets for raising the propagation angle of the light diffused by the diffusion sheets perpendicular to the liquid crystal panel 6 are provided. do. Accordingly, the light emitted from the light guide plate 10 is incident on the liquid crystal panel 6 via the plurality of optical sheets 8 via the diffusion sheet.

The light guide plate 10 is manufactured by injection molding by a mold, and a plurality of scattering patterns 13 are formed on the back surface. The plurality of scattering patterns 13 scatter light traveling to the rear surface of the light guide plate 10. The scattered light is reflected toward the liquid crystal panel 6 by the reflective sheet 12. Accordingly, the light guide plate 10 converts the light incident from the lamp through the incident surface into a planar light source and emits the light toward the liquid crystal panel 6.

In addition, the lower mold apparatus 32 is formed with a light guide plate resin material supply pipe 60 for supplying the light guide plate resin material supplied from the outside to the injection molding portion 46.

In the light guide plate manufacturing apparatus, in order to perform injection molding on the light guide plate, first, the upper mold apparatus 30 is transferred downward to be in contact with the lower mold apparatus 32. For this reason, the injection molding part 46 of the lower mold apparatus 32 has the shape of the light guide plate 10 by the side molding plate 44, the lower molding plate 42, and the upper molding plate 40.

The light guide plate 10 is finally completed by forming the scattering patterns 13 on the light guide plate 10 as shown in FIG. 3B using the screen silk printing method.

The light guide plate 10 on which the scattering patterns 13 are formed is stacked upside down on the reflective sheet 12 stacked on the support main 14 as shown in FIG. 1.

In the conventional liquid crystal display module, defects such as foreign matter inflow or scratches occur between the light guide plate 10 and the reflective sheet 12 due to assembly on the support main 14 on which the reflective sheet 12 is stacked. . In addition, in the conventional liquid crystal display module, optical losses 20a and 20b are generated due to the air layer between the light guide plate 10 and the reflective sheet 12. Furthermore, since the conventional liquid crystal display module has a structure in which the reflective sheet 12 is laminated on the support main 14 and then the light guide plate 10 is laminated, the number of manufacturing processes increases.
