Description

Narrow bezel display device {NARROW BEZEL PANEL DISPLAY}

The present invention relates to a narrow bezel display device, and more specifically, to a narrow bezel display device that can prevent seal uncuring and light leakage in a non-display area including a driving element.

Generally, liquid crystal displays display images by adjusting the light transmittance of liquid crystals using an electric field.

These liquid crystal display devices are roughly divided into vertical electric field type and horizontal electric field type depending on the direction of the electric field driving the liquid crystal.

In a vertical electric field type liquid crystal display device, the common electrode formed on the upper substrate and the pixel electrode formed on the lower substrate are arranged to face each other, and the liquid crystal in TN (Twisted Nematic) mode is driven by the vertical electric field formed between them.

This vertical electric field type liquid crystal display device has the advantage of a large aperture ratio, but has the disadvantage of having a narrow viewing angle of about 90 degrees.

A horizontal electric field type liquid crystal display device drives the liquid crystal in an in-plane switching (IPS) mode by a horizontal electric field between a pixel electrode and a common electrode arranged in parallel on a lower substrate. This horizontal electric field type liquid crystal display device has the advantage of a wide viewing angle of about 170 degrees.

On the other hand, the horizontal electric field type liquid crystal display device has the disadvantage of having a lower aperture ratio than the vertical electric field type liquid crystal display device because an electric field is not formed on the electrode and the liquid crystal above the electrode cannot be driven.

Currently, most liquid crystal displays have a structure in which a thin film transistor substrate on which thin film transistors form a matrix array and a color filter substrate on which a color filter is formed are bonded together, and then a liquid crystal layer is interposed between them.

The pixel area formed on the thin film transistor substrate and the pixel area formed on the color filter substrate must be joined so that they completely overlap each other.

To reduce errors during this cementation and alignment process, a color filter layer is sometimes formed on the thin film transistor substrate.

FIG. 1 is a plan view showing a conventional narrow bezel display device in which a wiring unit including a driving element is disposed, and FIG. 2 is a longitudinal cross-sectional view showing a conventional narrow bezel display device.

Referring to Figures 1 and 2, a conventional narrow bezel display device has a lower substrate. The lower substrate is TFT Galss.

The lower substrate (TFT Galss) includes a non-display area (NA) and a display area (AA).

A driving layer including a ground (GND), a driving element (GIP), and a Vcom wire is stacked on the lower substrate (TFT Galss) to be included in the non-display area (NA).

A protective layer (PAC) of a set thickness is laminated on top of the driving layer.

A seal with a set height is placed on top of the protective layer (PAC).

An upper substrate (CF Glass) is disposed on the top of the seal (SEAL), and a black matrix layer (BM) is provided between the bottom of the upper substrate (CF Glass) and the top of the seal (SEAL).

Here, due to the seal (SEAL), a liquid crystal layer is provided between the protective layer (PAC) and the black matrix layer (BM).

In particular, in the above structure, the black matrix layer (BM) is provided over the entire non-display area (NA) of the upper substrate (CF Glass).

Additionally, as described above, a driving element (GIP) for driving display elements formed in the display area (DA) is disposed in the non-display area (NA) of the lower substrate (TFT Glass).

Through the above structure, when curing the seal (SEAL), external UV light irradiated through the lower substrate is blocked by the driving layer containing the driving element (GIP) and cannot be substantially transmitted to the seal (SEAL). am.

In addition, even if the upper UV light is used through the upper substrate (CF Glass), the UV light cannot be transmitted to the seal (SEAL) due to the black matrix layer (BM) provided at the bottom of the upper substrate (CF Glass).

Due to the above configuration, conventionally, there is a problem in that the seal (SEAL) is not cured because the UV light transmitted through the upper and lower substrates (CF Glass, TFT Glass) has a transmittance lower than that required for curing the seal (SEAL). .

In addition, when the seal (SEAL) is a white seal, there is a problem in that light generated in the display area (AA) leaks to the outside through the uncured white seal.

The purpose of the present invention is to provide a narrow bezel display device that can prevent seal uncuring and light leakage in a non-display area including a driving element.

According to one aspect of the present invention for achieving the above-described object, the present invention includes a lower substrate having a display area and a non-display area; a driving layer disposed on the lower panel to be located in the non-display area and having a driving element and wiring; a protective layer disposed on the driving layer and having a groove opening at the top thereof; a pigment layer provided inside the protective layer to isolate the groove and the display area from each other; a black seal member whose lower end is inserted into the groove; an upper substrate disposed on top of the black seal member; and a black column spacer provided at the bottom of the upper substrate and spaced apart from the seal member to form an opening area.

In addition, the pigment layer includes a pair of red pigment layers disposed on the driving unit so as to be located on both lower sides of the groove, and a pair of red pigment layers disposed on top of the pair of red pigment layers, corresponding to both sides of the groove. It is desirable to have a pair of blue pigment layers.

Among the pair of blue pigment layers, the width of the blue pigment layer located below the opening region is preferably larger than the width of the opening region.

The top surface of the protective layer is preferably at the same level on the non-display area side and the display area side with the groove as a boundary.

The edge of the black column spacer is preferably inclined along the side of the seal member.

The pigment layer preferably has a gradually increasing slope from the side of the groove toward the display area.

It is preferable that the groove forms a narrowing slope from the top to the bottom, and that the seal member forms a shape corresponding to the slope forming the groove.

In the present invention, when curing a seal member, seal curing can be achieved using UV light introduced through an opening area provided between the seal member and the black column spacer.

In addition, in the present invention, when the driving element is included in the non-display area, light leakage is blocked using a black seal member, and a double pigment dam is formed at the bottom of the above-mentioned opening area where the seal member is not present to additionally prevent light leakage. can be prevented effectively.

In addition, according to the present invention, the seal member is inserted into a groove provided in the protective layer, thereby limiting the spread width of the seal member, thereby preventing shape deformation of the seal member due to the external temperature environment.

First, a first embodiment of the narrow bezel display device of the present invention will be described.

Figure 3 is a plan view showing the narrow bezel display device of the present invention.

Referring to FIG. 3, the narrow bezel display device of the present invention includes a display area (AA) and a non-display area (NA).

The non-display area (NA) is located outside the display area (AA) and corresponds to the bezel area.

The width of the non-display area (NA) may be 0.9 mm. Of course, other than the above width size, it can be set to 0.9 mm or less to achieve a narrow bezel.

FIG. 4 shows a first embodiment of the narrow bezel display device of the present invention, and is a longitudinal cross-sectional view taken along line II of FIG. 3, and FIG. 5 is a longitudinal cross-sectional view showing the completed arrangement of the seal member according to the present invention.

Referring to FIG. 4, the narrow bezel display device of the present invention has a lower substrate 100 having the above-described display area AA and non-display area NA. The lower substrate 100 is TFT glass.

A driving layer 200 is disposed on the top of the lower substrate 100. The driving layer 200 is located in the non-display area (NA).

The driving layer 200 is sequentially arranged from the edge of the display area AA to the Vcom wiring 220, the driving element 210, and the ground 230, which are adjacent to each other.

A protective layer 300 having a set thickness is laminated on the driving layer 200 and the display area AA.

A groove 310 having a set depth is provided at the top of the protective layer 300. The upper part of the groove 310 opens upward.

The shape of the groove 310 is preferably made to correspond to the shape of the seal member 600, which will be described later.

And, the pigment layer 400 according to the present invention is configured to be laminated on the top of the driving layer 200 and the top of the display area AA.

The configuration of the pigment layer 400 will be described.

The pigment layer 400 is composed of a first blue pigment layer 410, a red pigment layer 420, and a second blue pigment layer 430.

The first blue pigment layer 410 is laminated on the top of the driving layer 200 while being located inside the protective layer 300 so as to be located below the groove 310.

Here, a groove in which the red pigment layer 420 is located may be formed in the first blue pigment layer 410.

Accordingly, the first blue pigment layer 410 is formed in a first area stacked on the driving element 210 and the ground 230, and on the driving element 210, the Vcom wire 220, and the display area (AA). It can be divided into a second area that is stacked.

In the second area, another first blue pigment layer 410' forming the same layer as the first blue pigment layer 410 is stacked.

The first and second regions are arranged to the left and right bordering the above-mentioned groove portion.

A red pigment layer 420 is disposed in the groove portion.

Here, the thickness of the first blue pigment layer 410 and the red pigment layer 420 may be the same.

In addition, a second blue pigment layer 430 is laminated on the top of the red pigment layer 420, and the second blue pigment layer 430 is located on the side of the groove 310 provided in the protective layer 300. do.

That is, the second blue pigment layer 430 may be disposed on the side of the groove 310 and serve as a dam to isolate the groove 310 from the display area AA.

Here, the second blue pigment layer 430 is disposed on the side of the groove 310, and may be disposed in close contact with the side wall of the groove 310, or may be disposed spaced apart to form a set interval.

In addition, the second blue pigment layer 430 has a width greater than the width of the opening area (a), which will be described later, and covers the opening area correspondingly.

As shown in FIG. 5, the lower end of the seal member 600 is inserted into the groove 310 as described above.

The seal member 600 is preferably a black seal member.

The height of the seal member 600 is higher than the depth of the groove 310.

An upper substrate 800 disposed above the non-display area NA and the display area AA is disposed on the top of the seal member 600.

The upper substrate 800 is a color filter substrate.

Meanwhile, a black column spacer 700 is disposed at the bottom of the upper substrate 800.

The black column spacer 700 extends from the side of the seal member 600 to cover the top of the display area AA.

The lower end of the black column spacer 700 is spaced apart from the upper end of the protective layer 300 at a set interval.

In particular, the outer edge of the black column spacer 700 is disposed at a set distance from the seal member 600.

That is, an opening area (a) corresponding to the gap is provided between the seal member 600 and the black column spacer 700.

The width (W2) of the above-described second blue pigment layer 430 is wider than the width (W1) of the opening area (a) so as to correspond to the opening area (a) at the lower part of the opening area (a).

Here, the opening area (a) between the seal member 600 and the black column spacer 700 and the space between the black column spacer 700 and the top of the protective layer 300 are connected to each other to form a space in which liquid crystal flows ( achieves b).

Next, the operation of the first embodiment of the narrow bezel display device of the present invention described with reference to FIGS. 3 to 5 will be described.

Referring to FIG. 5, the driving element 210 according to the present invention is stacked on the lower substrate 100 in the same layer as the ground 230 and the Vcom wiring 220.

Accordingly, UV light emitted from the lower substrate 100 is not transmitted to the seal member 600 by the driving layer 200.

In this structure, an opening area (a) is provided between the seal member 600 provided at the bottom of the upper substrate 800 and the black column spacer 700.

The opening area (a) guides UV light irradiated from the top of the upper substrate 800 to flow into the liquid crystal flow space (b).

Accordingly, UV light introduced through the opening area (a) is transmitted to the side of the seal member 600.

Subsequently, since the seal member 600 exposed to the UV light can undergo a curing process, the problem of non-curing of the seal member can be solved.

At the same time, the pigment layer 400 according to the present invention is composed of a double pigment, so that the light generated in the display area (AA) penetrates the upper substrate 800 through the opening area (a) and the seal member 600. It is transmitted to the top to prevent light leakage in the non-display area (NA).

That is, the first blue pigment layer 410 according to the present invention is laminated on the driving layer 200 and the display area AA to primarily prevent light leakage.

Additionally, the second blue pigment layer 430 laminated on top of the red pigment layer 420 may be disposed on the side of the groove 310 to isolate the display area AA and the groove 310 from each other.

Accordingly, light generated in the display area AA may not be transmitted to the groove 310 by the second blue pigment layer 430.

In addition, the seal member 600 according to the present invention is itself composed of a black seal member, and can block light generated in the display area AA from being transmitted to the outside.

In conclusion, the first embodiment according to the present invention uses UV light introduced through the opening area (a) provided between the seal member 600 and the black column spacer 700 when curing the seal member 600. Thus, seal hardening can be achieved.

In addition, the red pigment layer 420 and the second blue pigment layer 430, which form a double pigment dam structure, correspond to the lower part of the opening area (a) between the seal member 600 and the black column spacer 700 and form an opening area. It is arranged to cover (a), and can block light generated in the display area (AA) from being transmitted to the opening area (a).

Accordingly, in the present invention, when the driving element 210 is included in the non-display area (NA), light leakage is blocked using the black seal member 600, and the seal member 600 is not present. By constructing a double pigment dam at the bottom of one opening area (a), additional light leakage can be effectively prevented.

In addition, the seal member 600 is configured to be inserted into the groove 310 provided in the protective layer 300, thereby limiting the spread width of the seal member 600. This also has the advantage of preventing shape deformation of the seal member 600 due to the external temperature environment.

Figure 6 is a longitudinal cross-sectional view showing another example of the second blue pigment layer according to the first embodiment of the present invention.

Referring to FIG. 6, in the pigment layer 400 according to the present invention, the second blue pigment layer 430' is disposed on the side of the groove 310 described above.

Here, the top of the second blue pigment layer 430' is configured to slope upward from the side of the groove 310 along the display area.

That is, an inclined surface 431 may be provided at the top of the second blue pigment layer 430'.

Accordingly, the second blue pigment layer 430' serves as a dam to isolate the display area AA and the groove 310 from each other, and also serves to cover the opening area a.

In particular, in the former case, the top of the second blue pigment layer 430' forms an incline in which the height increases as the top of the second blue pigment layer 430' moves away from the groove 310, so that the light generated in the display area AA is transmitted through the opening area ( It is possible to block transmission to a) more efficiently.

Next, a second embodiment of the narrow bezel display device of the present invention will be described.

FIG. 7 is a longitudinal cross-sectional view showing a second embodiment of the narrow bezel display device of the present invention, and FIG. 8 is a longitudinal cross-sectional view showing the completed arrangement of the seal member according to the present invention.

Referring to FIG. 7, the narrow bezel display device of the present invention has a lower substrate having the above-described display area and non-display area. The lower substrate is TFT glass.

Hereinafter, since the configuration of the driving layer 200 according to the present invention is the same as that described in the first embodiment, it will be omitted.

The pigment layer 500 according to the second embodiment of the present invention is configured to be laminated on the top of the driving layer 200 and the top of the display area AA.

The configuration of the pigment layer 500 will be described.

The pigment layer 500 consists of a pair of red pigment layers 510 and a pair of blue pigment layers 520.

The pair of red pigment layers 510 are stacked on top of the driving layer 200 and are located on both sides of the groove.

And, in the red pigment layer 510 along the display area AA side, another blue pigment layer 510' is disposed.

The other blue pigment layer 510' is stacked along the top of the display area AA.

On top of the pair of red pigment layers 510, the pair of blue pigment layers 520 are stacked.

Here, the pair of blue pigment layers 520 are arranged to surround both sides of the groove 310.

The blue pigment layer 520 may be arranged to be in close contact with the inner walls of both sides of the groove 310, or may be arranged to be spaced apart at a set interval.

In addition, the width W2 of the blue pigment layer 520 is wider than the width W1 of the opening area a provided between the seal member 600 and the clack column spacer 700.

Accordingly, the blue pigment layer 520 covers the opening area (a) from the bottom and prevents light generated in the display area (AA) from being transmitted to the opening area (a).

In addition, the blue pigment layer 520 covers the area between the seal member 600 and the edge of the upper substrate 800 to further prevent light leakage.

As described above, the lower end of the seal member 600 is inserted into the groove 310 whose both sides are surrounded by the blue pigment layer 520. The seal member 600 is preferably a black seal member.

Here, since the red pigment layer 420 and the second blue pigment layer 430 laminated thereon are provided on one side of the groove 310, the upper surface of the protective layer 300 shows that the pigment layer 400 is not provided. The groove 310 on the outer side of the device is at a relatively high level compared to the other side, so that the pigment layer 400, which acts as a dam, can be stably supported.

Next, the operation of the second embodiment of the narrow bezel display device of the present invention described with reference to FIGS. 7 and 8 will be described.

Referring to FIG. 7, the driving element 210 according to the present invention is stacked on the lower substrate 100 in the same layer as the ground 230 and the Vcom wiring 220.

An opening area (a) is provided between the seal member 600 provided at the bottom of the upper substrate 800 and the black column spacer 700.

The opening area (a) guides UV light irradiated from the top of the upper substrate 800 to flow into the liquid crystal flow space (b). Accordingly, UV light introduced through the opening area (a) is exposed to the side of the seal member 600.

Subsequently, since the seal member 600 exposed to the UV light can undergo a curing process, the problem of non-curing of the seal member 600 can be solved.

In addition, the pigment layer 500 according to the present invention is composed of a double pigment, and the blue pigment layer 520 is configured to surround both sides of the groove 310 and covers the opening area (a). The light generated in the display area (AA) is transmitted to the upper part of the upper substrate 800 through the opening area (a) and the seal member 600, thereby preventing light leakage from occurring in the non-display area (NA). there is.

That is, the red pigment layer 510 according to the present invention and the other blue pigment layer 510' adjacent to the red pigment layer 510 are stacked on the driving layer 200 and the upper part of the display area AA. Prevents light leakage.

Additionally, the blue pigment layer 520 stacked on top of the red pigment layer 510 is arranged to surround both sides of the groove 310 to isolate the display area AA and the groove 310 from each other.

Therefore, the light generated in the display area AA may not be transmitted to the groove 310 by the blue pigment layer 520, and by covering the opening area A, the light may not pass through the opening area A. This can prevent exposure to the outside.

In addition, the pigment layer 500 according to the present invention with a double pigment dam structure forms a shape that surrounds both sides of the groove 310 into which the lower end of the seal member 600 is inserted inside the protective layer 300, thereby forming a seal. It may also serve to indirectly support the posture of the member 600.

That is, the blue pigment layer 520 is arranged to surround both sides of the groove 310 inside the protective layer 300, so that it can serve as a reinforcing material to maintain the posture of the seal member 600 itself. .

In addition, the seal member 600 according to the present invention is itself composed of a black seal member, and can block light generated in the display area AA from being transmitted to the outside.

In conclusion, the second embodiment according to the present invention uses UV light introduced through the opening area (a) provided between the seal member 600 and the black column spacer 700 when curing the seal member 600. Thus, seal hardening can be achieved.

In addition, the red pigment layer 510 and the blue pigment layer 520, which form a double pigment dam structure, are arranged to cover the lower part of the opening area (a) between the seal member 600 and the black column spacer 700, displaying Light generated in the area AA can be blocked from being transmitted to the aperture area AA.

Accordingly, in the present invention, when the driving element 210 is included in the non-display area (NA), light leakage is blocked using the black seal member 600, and the seal member 600 is not present. By configuring a double pigment dam at the bottom of one opening area (a), additional light leakage can be efficiently prevented and the posture of the seal member 600 itself can be kept constant.

Additionally, the seal member 600 in the second embodiment is configured to be inserted into the groove 310 provided in the protective layer 300, thereby limiting the spread width of the seal member 600. This also has the advantage of preventing shape deformation of the seal member due to the external temperature environment.

Additionally, the top surface of the protective layer 300 is at the same level on the non-display area (NA) side and the display area (AA) side with the groove 310 as a boundary.

In this case, in the case of the second embodiment, a pair of blue pigment layers 520 forming the same level are provided on both sides of the groove 310.

Accordingly, the upper surface of the protective layer 300 can be made to be at the same level on both sides bordering the groove 310 so that the balance of the pair of blue pigment layers 520 acting as a dam can be maintained.

Figure 9 is a longitudinal cross-sectional view showing another example of a blue pigment layer according to the second embodiment of the present invention.

Referring to FIG. 9, in the pigment layer 500 according to the present invention, the blue pigment layer 520' is disposed on the side of the groove 310 described above, and the blue pigment layer located along the display area AA side. The top of 520' includes an inclined surface 521 that slopes upward from the side of the groove 310 along the display area AA.

Accordingly, the top of the blue pigment layer 520 has an inclination in which the height increases as the distance from the groove 310 increases, thereby further preventing the light generated in the display area AA from being transmitted to the opening area a. It can be blocked efficiently.

Figure 10 is a longitudinal cross-sectional view showing another example of a seal member according to the present invention.

Referring to FIG. 10, a groove 320 having an upper portion is formed in the protective layer 300 according to the present invention.

The groove 320 may have a shape whose width gradually narrows from the top to the bottom of the protective layer 300.

That is, the inner wall of the groove 320 is inclined from the top to the bottom.

In addition, in the blue pigment layer 520 provided on both sides of the groove 320, the surface corresponding to the groove 320 has an inclined surface corresponding to the slope of the inner wall of the groove 320.

Here, the blue pigment layer 520 may be spaced apart from both sides of the groove 320 or may be arranged to be in close contact.

Additionally, the lower end of the seal member 610 according to the present invention is configured to have a width that gradually narrows downward so as to be inserted into the groove 320.

Both sides of the seal member 300 configured as above form an inclination S that spreads upward.

Additionally, the opening area (a) provided between one side of the seal member 610 and the outer edge of the black column spacer 700 is configured to expand downward due to the inclination of the seal member 610.

Accordingly, since the UV light flowing in through the opening area (a) expands from the opening area (a) and is transmitted to the seal member 610, there may be an advantage of shortening the time required for seal curing.

11 is a partial cross-sectional view showing an example of another shape of the opening area according to the present invention.

Referring to FIG. 11, the opening area (a) according to the present invention is provided between the seal member 600 and the black column spacer 700.

Here, the outer edge of the black column spacer 700 is inclined 710 from the top downward, and is inclined toward the seal member 600.

Therefore, when UV light flows in through the opening area (a), the UV light may be guided to the seal member 600 through the slope 710 provided on the outside of the black column spacer 700.

This too can have the advantage of shortening the time required for seal curing.
