Description

[0001] LIQUID CRYSTAL DISPLAY DEVICE [0002]

The present invention relates to a liquid crystal display device capable of improving image quality.

As the era of informationization becomes full-scale, the display field for visually displaying electrical information signals is rapidly developing. Accordingly, studies are being continued to develop performance such as thinning, lightening, and low power consumption for various various flat display devices.

Typical examples of such flat panel display devices include a liquid crystal display device (LCD), a plasma display panel (PDP), a field emission display (FED) An electroluminescence display device (ELD), an electro-wetting display device (EWD), and an organic light emitting display device (OLED). Such flat panel display devices commonly include flat panel display panels for realizing images. A flat panel display panel is a structure in which a pair of substrates sandwiching a unique light emitting material or a polarizing material are face-to-face bonded.

Among them, the liquid crystal display device is an apparatus for displaying an image by using the optical anisotropy and the polarization property of liquid crystal. That is, the liquid crystal display device forms an electric field for deforming the arrangement direction of the liquid crystal in each pixel region in a state in which the elongated liquid crystal molecules are oriented in a predetermined initial direction, and adjusts the light transmittance of each pixel region, Display.

Accordingly, a general liquid crystal display device includes first and second substrates which are adhered to each other, and a liquid crystal layer interposed therebetween. The liquid crystal display device further includes first and second alignment layers formed on one surface of the first and second substrates facing each other and orienting the liquid crystal layer in the initial direction.

On the other hand, when the liquid crystal display device is in an active matrix driving mode (Active Matrix Driving Mode), the thin film transistor array is formed on one of the first and second substrates disposed on the lower side in the light emitting direction. Here, the thin film transistor array defines a plurality of pixel regions corresponding to the display region and independently controls the light emission amount of each pixel region.

FIG. 1A is a view showing a part of a general liquid crystal display device, and FIG. 1B is a view showing light leakage by the alignment layer in FIG. 1A.

1A, a general liquid crystal display device 10 includes a gate line (not shown) and a data line (not shown) formed in a direction crossing each other to define a plurality of pixel regions corresponding to the display region AA The non-display area NA and the non-display area NA are formed in the non-display area NA and the display area AA, And a link formed so as to connect the pad 12 with either the gate line or the data line in the link region 13. [

At this time, since the pad area 12 is narrower than the display area AA, the link area 13 is spread from the pad area 12 to the display area AA, A spacing region 14 is formed.

A sealing layer 15 for bonding between the first and second substrates is formed in a sealing area SA surrounding the display area of the non-display area. In this case, the sealing area SA includes a link area 13, And the spacing region (14). Therefore, the thickness of the sealing layer formed at a portion overlapping the link region 13 among the sealing regions SA is greater than the thickness of the sealing layer formed at the other portion overlapping the spacing region 14, Thin. As described above, if the thickness of the sealing layer varies depending on whether or not the seal is overlapped with the link, there is a problem that the reliability of the adhesion between the first and second substrates deteriorates.

Accordingly, the general liquid crystal display further includes a dummy pattern formed in a V-shape so as to fill the gap region 14 in order to secure reliability of adhesion between the first and second substrates. At this time, the dummy pattern is added to the interval region 14 to compensate for the change in the thickness of the sealing layer by the link.

On the other hand, the alignment layer 11 is formed by forming a gate line, a data line, a pad and a link on the first substrate, and then aligning the alignment material film applied to the display area on the first substrate.

The process of orienting the alignment material film is performed using a rubbing roll 20. At this time, as the rubbing roll 20 rotates toward the display area AA via the non-display area NA, the surface of the rubbing roll 20 is repeatedly engaged with the V-shaped pattern by the link and the dummy pattern And copied, and patterned in a V-shape.

Due to this, the alignment layer 11 is formed to include the first and second alignment regions 11a and 11b which are aligned in two orientation directions symmetrical to each other.

In the boundary region between the first and second alignment regions 11a and 11b, the liquid crystals can not be arranged in an appropriate initial direction. Therefore, as shown in Fig. 1B, The image quality deteriorates.

As described above, the general liquid crystal display device includes a dummy pattern formed in a V-shape in the interval region between the link regions in order to secure reliability of adhesion between the first and second substrates. As a result, the alignment layers are aligned in two mutually symmetric alignment directions, resulting in a problem that the light leakage 16 in the form of a vertical line corresponding to the boundary region in which the alignment direction changes and the resulting image quality deteriorate.

The present invention relates to a liquid crystal display device including a dummy pattern for preventing a change in the thickness of a sealing layer according to overlapping with a link, and a method of manufacturing the same.

The liquid crystal display device according to an embodiment of the present invention includes at least one dummy pattern formed in a linear shape in a single direction in a space region between two link regions.

By such a dummy pattern, it is possible to prevent a pattern having a specific direction from repeating in the moving direction of the rubbing roll in the link region and the interval region. Therefore, even if the rubbing roll rotates through the non-display region and moves toward the display region side, the surface of the rubbing roll can be maintained in a design state having a single direction without repeated contact with a pattern having a specific direction, Can be oriented in a single direction.

As a result, it is possible to prevent the generation of light leakage in the form of a vertical line by the orientation layer oriented in mutually opposing two or more directions, and the image quality of the liquid crystal display device can be improved.
