Description

Liquid crystal display device {LIQUID CRYSTAL DISPLAY DEVICE}

The present invention relates to a liquid crystal display device, and particularly to a liquid crystal display device capable of implementing a narrow bezel.

As the information society develops, the demand for display devices for displaying images is increasing in various forms. Compared to conventional cathode ray tube displays (CRT), flat panel displays including thinner and lighter liquid crystal displays (LCDs), plasma displays (PDPs), or organic electroluminescent devices (OLEDs) are being actively researched and commercialized. . Among these, liquid crystal displays are currently widely used due to their advantages of miniaturization, weight reduction, thinness, and low-power operation.

Generally, a liquid crystal display device is composed of a TFT (Thin Film Transistor) substrate and a color filter bonded to form a liquid crystal panel, and a backlight assembly that provides light to the liquid crystal panel is installed. . In this liquid crystal display device, when a predetermined voltage is applied to the TFT formed on the TFT substrate, the arrangement of the liquid crystals enclosed in the liquid crystal panel changes, and the optical characteristics of the light passing through the polarizer and liquid crystal change, and the light passes through the color filter while changing. It is a display means that outputs colored images.

These liquid crystal displays are trending toward slimmer and lighter weight in order to secure competitiveness, and in particular, the width between the outer line of the display panel and the active display area where the screen is actually displayed (hereinafter referred to as 'bezel' in this specification) ) Development is underway to reduce the outer size of the video display device by reducing the size of the screen. When the bezel width is reduced, immersion in the screen improves and the screen appears larger.

Hereinafter, take a look with reference to Figures 1 to 3.

Generally, when a case top is applied to a liquid crystal display panel for grounding and light leakage prevention, the bezel width is implemented to be around 7.0 mm (see Figure 1), but recently, cover shield parts have been used to slim the bezel width. Alternatively, side sealing process technology is used.

When using a cover shield, there is no problem in the process because it can be applied to the liquid crystal display device using existing equipment. However, to ensure reliability, an attachment width of 1.2 mm or more is required, so the bezel width is 2.8 mm. It cannot be reduced below (see Figure 2). In addition, when using the side sealing method, it is effective in preventing ESD (Electro Static Discharge) and light leakage, but the bezel width cannot be reduced to less than 3.9 mm (see Figure 3) and the facility investment cost is high, so some models It can only be applied to , and there is a problem that the process becomes complicated due to the addition of the side sealing process.

Therefore, there is a need for a solution to implement a slim bezel width while preventing an increase in facility investment costs or process complexity.

The purpose of the present invention is to provide a liquid crystal display device designed to have a slim bezel width.

The liquid crystal display device of the present invention includes a polarizing plate including a step portion at an edge area, a liquid crystal panel including a liquid crystal layer between the first substrate and the second substrate below the polarizing plate, a backlight unit below the liquid crystal panel, and a liquid crystal panel below the backlight unit. It includes a cover shield that extends to the upper part and overlaps the step portion of the polarizer plate, and the end portion of the step portion of the polarizer plate is provided to contact the cover shield.

According to one embodiment of the present invention, a cover shield may be provided below the stepped portion of the polarizer. In this case, the stepped portion of the polarizer includes a surface treatment layer, a first protective film layer below the surface treatment layer, and a polarizer layer below the first protective film. , It may be a laminate including a second adhesive layer below the polarizer layer.

According to one embodiment of the present invention, the overlap width of the polarizer step portion and the cover shield may be 0.5 to 1.5 mm.

In addition, according to one embodiment of the present invention, the width of the bezel portion supporting the edge of the liquid crystal panel may be 0.5 mm to 1.6 mm, so the bezel width can be significantly slimmed.

Since the liquid crystal display device of the present invention is designed to have a slim bezel width, it is possible to implement a narrow bezel with a significantly reduced bezel width.

The step portion A of the polarizer 10 refers to an area where a height difference exists at one edge of the polarizer 10.

As mentioned above, in order to implement a narrow bezel in a liquid crystal display device, a cover shield was applied as a part or a side sealing method was used. However, when using a cover shield, the minimum bezel width that can be realized was about 2.8 mm, and the side sealing method was used. When used, the minimum bezel width that could be realized was around 3.9 mm, so it did not meet the needs of consumers. Additionally, in the case of the side sealing method, there has been a problem that it is uneconomical and the process becomes complicated due to increased facility investment costs.

Inspired by this, the present invention includes a step portion (A) in one edge area of the polarizer 10, and the step portion (A) of the polarizer 10 overlaps a cover shield to be described later, so that the bezel (B) width This design makes it possible to implement a narrow bezel with a significantly reduced bezel (B) width.
