[0001] LIQUID CRYSTAL DISPLAY DEVICE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display device, and more particularly to a lightweight, thin and narrow bezel type liquid crystal display device.

A liquid crystal display device (LCD), which is advantageous for moving picture display and has a large contrast ratio and is actively used in TVs and monitors, exhibits optical anisotropy and polarization properties of a liquid crystal, And the like.

Such a liquid crystal display device has a liquid crystal panel in which a liquid crystal panel is interposed between two adjacent substrates through a liquid crystal layer as an essential component and changes the alignment direction of the liquid crystal molecules in an electric field in the liquid crystal panel to realize a difference in transmittance do.

In this case, since the liquid crystal panel does not have its own light emitting element, a separate light source is required to display the difference in transmittance as an image. To this end, a backlight unit having a light source is disposed on the back surface of the liquid crystal panel .

The backlight unit includes a light source and is divided into a direct type and an edge type according to the position of the light source.

A direct-type backlight unit is a method in which light emitted from a light source is directly supplied to a liquid crystal panel by disposing a light source under the liquid crystal panel. In a side-type backlight unit, a light guide plate is disposed under the liquid crystal panel, So that the light emitted from the light source is indirectly supplied to the liquid crystal panel by using refraction and reflection in the light guide plate.

FIG. 1 is a cross-sectional view of a conventional side-view type liquid crystal display device, and FIG. 2 is a perspective view partially showing a coupling structure of a plurality of optical sheets and a cover bottom.

As shown in Fig. 1, a liquid crystal display device 1 includes a liquid crystal panel 10 composed of first and second substrates 12 and 14 and a backlight unit 20 located behind the liquid crystal panel.

The liquid crystal panel 10 is a part that plays a key role in image display. The first and second substrates 12 and 14 constituting the liquid crystal panel 10 include first and second polarizers (19a, 19b), respectively.

The backlight unit 20 includes a light source disposed on one side of the cover bottom 50, a reflection plate 25 seated on the cover bottom 50, a light guide plate 23 positioned above the reflection plate 25, And a plurality of optical sheets 21 interposed on the upper side of the light guide plate 23.

2, the plurality of optical sheets 21 includes a plurality of hooks 21a protruding along a circumferential edge of the optical sheet 21 at a predetermined width c, And includes an insertion groove into which the protrusion 54a of the cover bottom 50 can be inserted so as to fix the plurality of optical sheets 21 to the cover bottom 50. [

The liquid crystal panel 10 and the backlight unit 20 are modularized through the support main body 30, the side cover 40, the cover bottom 50, and the coupling member 70.

When the backlight unit 20 including the light source, the reflection plate 25, the light guide plate 23 and the plurality of optical sheets 21 is placed on the cover bottom 50, the cover bottom 50 and the support main (30) are screwed through the first screw (s1) and fixed to each other at their sides.

The side cover 40 and the side cover 40 are engaged with each other and the side cover 40 and the support main body 30 are fixed to each other through the second screw s2, And the liquid crystal panel 10 and the backlight unit 20 are integrated and modularized. At this time, a bonding pad 80 is provided between the liquid crystal panel 10 and the backlight unit 20 to prevent light leakage.

Here, the side cover 40 is configured to frame the side surface of the backlight unit 20 instead of the top cover that edges the edge of the liquid crystal panel 10, so that the liquid crystal panel 10 can have a wider display area.

The joining member 70 is for fixing and modifying the liquid crystal panel 10 to the backlight unit 20 and is fixed to the back surface of the liquid crystal panel 10 through an adhesive material such as a UV adhesive, And is engaged with the side cover 40.

As described above, the liquid crystal panel 10 and the backlight unit 20 are modularized through the support main 30, the side cover 40, the cover bottom 50, and the coupling member 70, There is an advantage in that a wide image can be realized. On the other hand, as the modules are modularized, the width a of the bezel becomes wider and the whole thickness becomes thicker.

The total thickness of the liquid crystal display device 1 is increased and the adhesive pad 70 is provided between the liquid crystal panel 10 and the backlight unit 20 to prevent light leakage The thickness (b) of the electrode (80) is also increased.

Since the plurality of hook portions 21a of the plurality of optical sheets 21 are formed to have a constant width c for the strength because the insertion grooves are provided at the center of the inner portion, There is a problem that the length of the side surface of the support main body 30 becomes long and the structure becomes complicated. The cover bottom 50 and the support main 30 and the support main 30 and the side cover 40 are fixed to the side of the liquid crystal panel 10 and the backlight unit 20 by the first screw s1, 2 screw (s2), the width (a) of the bezel is widened.
