The second substrate 4b includes a plurality of thin film transistors (hereinafter referred to as TFTs) arranged in a matrix form. Here, the source electrode of the TFT is connected to the data line, and the gate electrode is connected to the scan line. The drain electrode of the TFT is connected to a pixel electrode made of transparent indium tin oxide (ITO) as a conductive material. Such a TFT is turned on when the scan signal is supplied to the scan line to supply the data signal supplied from the data line to the pixel electrode.

To this end, an integrated circuit 6 is inserted into one side of the second substrate 4b, and a data signal and a scan signal are supplied from the integrated circuit 6. A protective layer 8 is applied around the integrated circuit 6.

The first substrate 4a is disposed to face the second substrate 4b. The common electrode made of ITO is coated on the front surface of the first substrate 4a. A predetermined voltage is applied to the common electrode, thereby forming a predetermined electric field between the common electrode and the pixel electrode. The arrangement angle of the liquid crystal injected between the first substrate 4a and the second substrate 4b is changed by the electric field, and the light transmittance is changed according to the changed arrangement angle to display a desired image.

The light guide plate 18 supplies light supplied from the light emitting diodes 12 to the liquid crystal display panel 4. That is, the light guide plate 18 supplies the light supplied from its side to the liquid crystal display panel 4 located above it.

The reflecting plate 20 is located on the rear surface of the light guide plate 18 to re-inject light incident from the light guide plate 18 to the light guide plate 18. That is, the reflecting plate 20 improves the light efficiency by resupplying the light incident on the light guide plate 18.

The optical sheets 10 improve the luminance and the like of the light supplied from the light guide plate 18 and supply them to the liquid crystal display panel 4.

The bottom chassis 22 is made of aluminum or the like and fixed to the mold frame 16. This bottom chassis 22 provides a predetermined strength to the liquid crystal display.

Such a conventional liquid crystal display includes various configurations in the backlight assembly 50. Therefore, there is a problem in that the manufacturing cost of the liquid crystal display increases.

In addition, in assembling the backlight assembly, since the reflective plate 20, the mold frame 16 and the bottom chassis 22 are all separated, the process and assembly process is complicated and expensive, and the thickness of the backlight assembly is increased. The disadvantage is that it becomes thicker.

Accordingly, an object of the present invention is to provide a liquid crystal display device having a buffer unit in a corner area of a bottom chassis to reduce manufacturing costs, minimize thickness of the backlight assembly, and enhance buffering characteristics against external impact of the liquid crystal display device.

 Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to FIGS. 2 to 11 which can be easily implemented by those skilled in the art.

2 is a diagram illustrating a liquid crystal display according to a first embodiment of the present invention, and FIG. 3 is a combined plan view of the liquid crystal display of FIG. 2.

Referring to FIG. 2, the liquid crystal display 100 according to the first exemplary embodiment of the present invention includes a liquid crystal display panel 104, a backlight assembly 150, and a bottom chassis (or bezel) 122.

The liquid crystal display panel 104 displays a predetermined image. To this end, the liquid crystal display panel 104 includes a first substrate 104a, a second substrate 104b, and a liquid crystal (not shown) injected therebetween.

The second substrate 104b includes a plurality of TFTs arranged in a matrix form. Here, the source electrode of the TFT is connected to the data line, and the gate electrode is connected to the scan line. The drain electrode of the TFT is connected to a pixel electrode made of a transparent conductive material. Such a TFT is turned on when the scan signal is supplied to the scan line to supply the data signal supplied from the data line to the pixel electrode.

To this end, an integrated circuit 106 is inserted into one side of the second substrate 104b, and a data signal and a scan signal are supplied from the integrated circuit 106. A protective layer 108 is applied around the integrated circuit 106.

The first substrate 104a is disposed to face the second substrate 104b. The common electrode made of a transparent material is coated on the front surface of the first substrate 104a. When a predetermined voltage is applied to the common electrode, a predetermined electric field is formed between the common electrode and the pixel electrode. The arrangement angle of the liquid crystal injected between the first substrate 104a and the second substrate 104b is changed by this electric field, and the light transmittance is changed according to the changed arrangement angle to display a desired image.

The backlight assembly 150 includes light emitting diodes 112, a light emitting diode substrate 114, a light guide plate 118, and optical sheets 110.

The light emitting diodes 112 generate light having a predetermined brightness in response to a driving signal supplied from the light emitting diode substrate 114.

The LED substrate 114 supplies a driving signal to the LEDs 112 in response to a control signal supplied from the outside.

The light guide plate 118 supplies light supplied from the light emitting diodes 112 to the liquid crystal display panel 104. That is, the light guide plate 118 supplies the light supplied from its side to the liquid crystal display panel 104 positioned above it.

The optical sheets 110 improve the luminance of the light supplied from the light guide plate 118 and supply them to the liquid crystal display panel 104.

The bottom chassis 122 is formed to allow the light guide plate 118, the optical sheets 110, and the light emitting diode substrate 114 to be inserted therein.

In detail, the bottom chassis 122 is formed with a side portion 124 flatly positioned on the outer surface to surround four external surfaces, and has a predetermined step in the side surface portion 124 to form a light guide plate 118 and an optical sheet. An inner portion 126 into which the field 110 is inserted and an extension portion 128 extending from the outer side of the side portion 124 are provided.

The inner portion 126 is formed with a predetermined step from the side portion 124. Accordingly, a predetermined space is formed in the inner portion 126, and the light guide plate 118, the optical sheets 110, the light emitting diode substrate 114, and the light emitting diode 112 are inserted into the space.

That is, in the present invention, the light guide plate 118 and the optical sheets 110 may be inserted into the inner portion 126 of the bottom chassis 122, thereby removing the mold frame. As such, when the mold frame is removed, the manufacturing cost can be reduced as compared with the related art. In addition, the bottom chassis 122 formed of aluminum or the like provides higher strength than the conventional mold frame. When the mold frame is removed, the liquid crystal display may be slimmer than the conventional art.

In addition, the elongation part 128 is formed for the purpose of mitigating an impact applied from the outside, and thus the liquid crystal display panel 104 may be stably protected.

In particular, the edge portion of the elongated portion 128 is characterized in that the buffer unit 140 is formed to have a predetermined elasticity, respectively.

That is, the buffer unit 140 is formed in one region of the elongated portion, that is, each corner region as shown as an example, and is formed in a shape having elasticity.

The elastic shape may be implemented in various ways, and as shown in FIG. 2, the U-shaped leaf spring has been described as an example, but this is an embodiment of the shock absorber 140 according to the present invention. ) Is not necessarily limited thereto.

The embodiment of the present invention is characterized in that the existing mold frame is removed through the structure of the bottom chassis 122 described above.

However, when the mold frame is removed in this way, the cost can be reduced, the structure can be made slim, and the weight can be realized. However, when the external impact on the liquid crystal display device occurs, the liquid crystal display panel is finely distorted due to a slight twist. Cracks due to the panel 104 in direct contact with the bottom chassis 122 is prone to occur.

Accordingly, in the embodiment of the present invention, the buffer unit 140 is formed on one side of the extension part 128 of the bottom chassis 122 to compensate for such a disadvantage, so that even when an external impact occurs, the liquid crystal display panel 104 may be directly connected to the liquid crystal display panel 104. It is characterized by being able to prevent the impact from being applied.

That is, since the buffer unit 140 is provided, the contact time is increased by the buffer unit 140 when an external shock is applied to the liquid crystal display, thereby reducing the amount of impact applied to the liquid crystal display panel.

The impact amount is represented by a value obtained by dividing the load applied by the contact time, which can be reduced as the contact time increases by the buffer part.

2 and 3, the buffer unit 140 may have a U-shaped leaf spring shape, and the size and dimensions of the buffer unit 140 may include the size of the liquid crystal display panel and the liquid crystal display. The design depends on the distance from the outside of the panel to the side in the bottom chassis.

That is, the embodiment of the present invention is formed in the structure of the shock absorbing portion 140, the one surface of the bottom chassis that is first contacted during the external impact of the liquid crystal display, the elasticity, so as to reduce the external impact It is characterized by sufficient deformation.

On the other hand, light incident from the light guide plate 118 to the inner portion 126 is reflected by the inner portion 126 and is supplied back to the light guide plate 118. That is, since the bottom chassis 122 is formed of aluminum capable of reflecting light, the reflecting plate may be removed. In addition, in the present invention, since the bottom chassis 122 provides high strength (i.e., high strength is provided by the side portions 124 located on four sides), the top chassis can be eliminated as compared with the prior art.

In practice, the reflector and top chassis in the present invention can be added or removed by the designer. For example, as illustrated in FIG. 4, a reflective plate 120 positioned between the light guide plate 118 and the bottom chassis 122 may be added, and a top chassis 102 positioned on the liquid crystal display panel 104 may be added. . The reflector 120 improves light efficiency by re-incident light supplied from the light guide plate 118 to the light guide plate 118. The top chassis 102 is fixed to the bottom chassis 122 to prevent the liquid crystal display panel 104 from flowing and provide a predetermined strength.

5 is a cross-sectional view when the liquid crystal display of FIG. 2 is coupled.

Referring to FIG. 5, the light guide plate 118 and the optical sheets 110 are inserted into the inner portion 126 of the bottom chassis 122. After the light guide plate 118 and the optical sheets 110 are inserted into the inner portion 126, the adhesive tape 130 is attached to the side portion 124. The liquid crystal display panel 104 and the bottom chassis 122 are stably fixed by mounting the liquid crystal display panel 104 on the adhesive tape 130. Here, the adhesive tape 130 may be replaced with an adhesive material (for example, a bond).

In addition, an extension part 128 extending from an outer side of the side part 124 of the bottom chassis 122 is formed, and a buffer part (not shown) formed to have a predetermined elasticity in each corner area of the extension part 128. Characterized in that it is provided.

Here, as described above, the buffer part is formed in one region, that is, in each corner region as shown as an example, and is formed in a shape having elasticity.

In this way, by forming the buffer part on one side of the extension part 128, it is possible to prevent a direct shock from being applied to the liquid crystal display panel 104 even when an external impact occurs. That is, since the buffer unit is provided, the contact time is increased by the buffer unit during external impact applied to the liquid crystal display, thereby reducing the amount of impact applied to the liquid crystal display panel.

FIG. 6 is a diagram illustrating the light guide plate illustrated in FIG. 2.

Referring to FIG. 6, the light guide plate 118 of the present invention is formed with a stepped portion 119 having a step shape. The stepped part 119 is configured of at least one step lowered in a step shape from the outside of the light guide plate 118 to the inside. The stepped portion 119 prevents the flow of the optical sheets 110 positioned on the light guide plate 118. In other words, when the optical sheets 110 are seated on the stepped portion 119, the flow may be prevented by the stepped portion 119, thereby preventing deterioration of characteristics due to the flow of the optical sheets 110. .

To this end, the stepped portions 119 are formed to face each other at both sides of the light guide plate 118. When the stepped portion 119 is formed to face each other at both sides of the outer region of the light guide plate 118, it is possible to stably prevent the flow of the optical sheets 110. In addition, the stepped portion 119 may be formed on all sides of the light guide plate 118 formed in a quadrangular shape to prevent the flow of the optical sheets 110.

Here, the source electrode of the TFT is connected to the data line, and the gate electrode is connected to the scan line. The drain electrode of the TFT is connected to a pixel electrode made of a transparent conductive material. Such a TFT is turned on when the scan signal is supplied to the scan line to supply the data signal supplied from the data line to the pixel electrode.

To this end, an integrated circuit 206 is inserted into one side of the second substrate 204b, and a data signal and a scan signal are supplied from the integrated circuit 206. A protective layer 208 is applied around the integrated circuit 206.

The first substrate 204a is disposed to face the second substrate 204b. A common electrode made of a transparent material is coated on the entire surface of the first substrate 204a. When a predetermined voltage is applied to the common electrode, a predetermined electric field is formed between the common electrode and the pixel electrode. Such an electric field changes the arrangement angle of the liquid crystal injected between the first substrate 204a and the second substrate 204b, and the light transmittance is changed according to the changed arrangement angle to display a desired image.

The backlight assembly 250 includes a light guide plate 218 and optical sheets 210.

The light guide plate 218 supplies light supplied from the light emitting diodes to the liquid crystal display panel 204. Here, the light guide plate 218 includes first holes 251 and second holes 260 formed on the outer side of one side. The light emitting diode is inserted into the first holes 251. The light emitting diodes inserted into the first holes 251 supply predetermined light to the light guide plate 218. To this end, a flexible printed circuit (FPC) (not shown) is connected to the light emitting diodes to supply driving signals to the light emitting diodes. In this case, the fusible printed circuit FPC is connected to the light emitting diode via the second holes 260. Accordingly, components of the fusible printed circuit FPC are inserted into the second holes 260.

The optical sheets 210 improve the luminance of the light supplied from the light guide plate 218 and supply them to the liquid crystal display panel 204.

The bottom chassis 222 is formed so that the light guide plate 218 and the optical sheets 210 can be inserted. In detail, the bottom chassis 222 may include a side portion 224 that is positioned on the outer side of the side, an inner side 226 positioned with a predetermined step inside the side portion 224, and an outer side of the side portion 224.

In addition, since the bottom chassis 222 is formed of aluminum or the like, it may provide a higher strength than the conventional mold frame.

In addition, since the bottom chassis 222 is formed of aluminum, the reflective plate may be removed between the light guide plate 218 and the inner portion 226. In other words, since the light supplied from the light guide plate 218 is reflected at the inner portion 226, the reflective plate can be further removed. In addition, in the second embodiment of the present invention, the top chassis may be omitted because the bottom chassis 222 provides high strength.

In fact, in the second embodiment of the present invention the reflector and top chassis can be added or removed by the designer. For example, as illustrated in FIG. 8, a reflective plate 220 positioned between the light guide plate 218 and the bottom chassis 222 may be added, and a top chassis 202 may be added on the liquid crystal display panel 204. The reflective plate 220 improves the light efficiency by re-incident the light supplied from the light guide plate 218 to the light guide plate 218.
