Description

[0001] The present invention relates to a liquid crystal display device,

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

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.

However, 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 having a light source is disposed on the back surface of the liquid crystal panel.

A typical backlight unit is divided into an edge type and a direct type according to the arrangement structure of the lamp. The edge type has a structure in which one or a pair of lamps are disposed on one side of the light guide plate, Two pairs of lamps are disposed on both side portions of the light guide plate, and the direct type lamp has a structure in which several lamps are disposed under the optical sheet.

Here, the edge type is easier to manufacture than the direct type, and is advantageous in that it is thin, light in weight, and low in power consumption as compared with the direct type.

1 is a sectional view of a liquid crystal display device including an edge type backlight unit.

A typical edge type liquid crystal display device includes a liquid crystal panel 10, a backlight unit 20, a support main 30, a cover bottom 50, and a top cover 40.

The liquid crystal panel 10 is constituted by first and second substrates 12 and 14 which are in contact with each other with a liquid crystal layer interposed therebetween, which plays a key role in image display.

A backlight unit 20 is provided behind the liquid crystal panel 10.

The backlight unit 20 includes an LED assembly 29 arranged along the longitudinal direction of at least one side edge of the support main body 30, a white or silver reflective plate 25 seated on the cover bottom 50, 25, and a plurality of optical sheets 21 interposed therebetween.

The LED assembly 29 is formed on one side of the light guide plate 23. The LED assembly 29 includes a plurality of LEDs 29a and an LED PCB 29b on which a plurality of LEDs 29a are mounted. .

And reference numerals 19a and 19b denote polarizing plates attached to the front and back surfaces of the liquid crystal panel 10 to control the polarization direction of light, respectively.

On the other hand, in recent years, such a liquid crystal display device is required for a narrow bezel in which a display area is wide and a bezel area which is a non-display area other than the display area is formed as small as possible.

However, since there are too many components for modulating the liquid crystal panel 10 and the backlight unit 20, there is a limitation in reducing the width of the bezel of the liquid crystal display device.

When the thickness of the support main body 30 is reduced in order to reduce the width of the bezel of the liquid crystal display device, light leakage occurs as shown in FIGS. 2A and 2B due to light transmitted through the support main body 30.

In other words, since the support main 30 is made of a synthetic resin mold material through which a certain amount of light is transmitted, when the thickness of the support main 30 is reduced, some light passes through the support main 30, .

Such light leakage can be visually confirmed, which causes a problem that the quality of a liquid crystal display device such as brightness and image quality deteriorates.
