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 of a transverse electric field type in which light leakage does not occur in a black state and a method of manufacturing the same.

In general, a liquid crystal display device is a thin display device that displays an image by using optical anisotropy and birefringence characteristics of a liquid crystal packed between two bonded substrates.

Hereinafter, a general configuration of the liquid crystal display device will be described with reference to the drawings.

1 is a perspective view schematically showing a configuration of a conventional liquid crystal display device.

As shown in the figure, a typical color liquid crystal display (LCD) is manufactured in a state where the color filter substrate B1 and the array substrate B2 are bonded together with the liquid crystal layer 14 interposed therebetween.

The color filter substrate B1 includes a transparent substrate 5 on which a plurality of pixel regions P are defined and color filters 8a, 8b, and 8c formed on the surface of the substrate 5, 8c and a black matrix 6 formed between the color filters 8a, 8b, 8c.

A common electrode 18 is formed on the front surface of the substrate 5 on which the color filters 8a, 8b and 8c and the black matrix 6 are formed.

The array substrate B2 includes a transparent substrate 22 on which a plurality of pixel regions P are defined and a plurality of pixel regions P formed on one side of the pixel region P and on the other side The gate electrode 30, the active layer 32, the source electrode 34, and the drain electrode 36 (not shown), which are located at intersections of the wiring 12 and the data line (not shown) And a thin film transistor T constituted by a thin film transistor T.

And a pixel electrode 17 located in the pixel region P and in contact with the drain electrode 36.

In the above-described configuration, the liquid crystal layer 14 is initially arranged by an alignment film (not shown) located between the color filter substrate B1 and the array substrate B2 and rubbed on the surface.

Although not shown, a plurality of column spacers 20 are provided between the color filter substrate B1 and the array substrate B2 to maintain a gap between the two substrates.

In the above-described configuration, when a voltage is applied between the pixel electrode 17 and the common electrode 18, an electric field is generated in the vertical direction, and the liquid crystal 14 is driven by the electric field, The image can be expressed by the light transmittance.

In this case, if the the liquid crystal layer is also twisted twisted nematic liquid crystal 90 ^o layer assumed (twisted nematic LC), a first polarizing plate 40 is arranged such that polarization axes perpendicular to each other the lower and upper part of the liquid crystal panel (LCD) And the second polarizing plate 42 are positioned.

In this case, since the liquid crystal layer 14 is formed in a state of being twisted by 90 ^o , when the voltage is not applied, the polarizing axes of the first polarizing plate 40 and the second polarizing plate 42 are aligned in a liquid crystal (not shown) It can be seen that it is in a state parallel to the optical axis of FIG.

Accordingly, in a state where no voltage is applied, light is driven in a normally white state in which light travels through the first polarizer 40, the liquid crystal layer 14, and the second polarizer 42.

On the contrary, when a high voltage is applied to the liquid crystal panel (LCD), the liquid crystal layer 14 is vertically configured and the light does not undergo a phase change. Therefore, light passing through the first polarizer 40 is directly transmitted to the liquid crystal layer 14 Accordingly, the first polarizing plate 40 and the second polarizing plate 42 whose polarizing axis is perpendicular to the first polarizing plate 40 are absorbed without passing through the second polarizing plate 42 to display a black state.

At this time, since the twisted nematic liquid crystal layer is forced to display the black state by forcibly specifying the orientation of the liquid crystal by applying a high voltage, the liquid crystal is hardly affected by the initial alignment state in displaying the black state. That is, a black color having a high color purity can be obtained.

However, since such a TN liquid crystal panel is very weak in view angle, a transverse electric field type liquid crystal display device having a structure capable of securing a wide viewing angle has been proposed.

FIG. 2 is a cross-sectional view schematically showing the configuration of a transverse electric field type liquid crystal display device, and FIG. 3 is an enlarged cross-sectional view of FIG.

As shown in the figure, a conventional transverse electric field type liquid crystal panel B has a color filter substrate B1 and an array substrate B2 opposed to each other, and a liquid crystal layer B is formed between the color filter substrate and the array substrates B1 and B2. (LC) is interposed.

The array substrate B2 includes a thin film transistor T, a common electrode 70, and a pixel electrode 82 for each of a plurality of pixels P defined in a transparent insulating substrate 50.

The thin film transistor T includes a gate electrode 54, a semiconductor layer 58 formed above the gate electrode 54 with an insulating film 56 interposed therebetween, And drain electrodes 60 and 62.

In the above-described configuration, the common electrode 70 and the pixel electrode 82 are formed on the same substrate 50 in parallel to each other.

Although not shown, a gate wiring (not shown) extending along one side of the pixel P and a data wiring (not shown) extending in a direction perpendicular thereto are formed, and a voltage is applied to the common electrode 70 (Not shown) is formed.

The color filter substrate B1 has a black matrix 92 formed on a transparent insulating substrate 90 at a portion corresponding to the gate wiring (not shown), the data wiring (not shown) and the thin film transistor T, Color filters 94a and 94b are configured to correspond to the pixels P. [

The liquid crystal layer LC is operated by the horizontal electric field 78 between the common electrode 70 and the pixel electrode 82.

The liquid crystal layer LC has a long axis aligned horizontally with the common electrode 70 and the pixel electrode 82 and a liquid crystal layer LC having a polarization axis parallel to the optical axis of the liquid crystal LC 1 polarizing plate 76 and a second polarizing plate 78 having a polarization axis perpendicular to the first polarizing plate 76 are formed on the liquid crystal panel B.

In the transverse electric field system liquid crystal panel having the above-described configuration, when the initial voltage is not applied, the light passing through the first polarizer 76 passes through the liquid crystal layer LC and undergoes a phase of? / 2, And is perpendicular to the transmission axis of the polarizing plate 78.

Therefore, in the transverse electric field type liquid crystal display device, light having passed through the liquid crystal layer LC is absorbed without passing through the second polarizing plate 78, and is driven in a normally white mode indicating a black state .

As described above, the transverse electric field type liquid crystal display device is very sensitive to the confusion of the initial alignment state of the liquid crystal because it exhibits a black state when no voltage is applied.

This will be described below with reference to Equation 1 showing transmittance (T).

The transmittance (T) of light transmitted through the liquid crystal panel (B) can be expressed by the following Equation (1).

------(1)

------(One)

Here, T _o is a coefficient and is a value mainly determined by the transmittance of the polarizers 76 and 78 used in the liquid crystal panel B, and θ (E) is an angle formed by the alignment direction of the liquid crystal (effective optical axis of the liquid crystal layer) , E is the applied electric field intensity, d _eff is the effective thickness of the liquid crystal layer, Δn is the refractive index anisotropy of the liquid crystal, and λ is the wavelength of light.

As described above, the transverse electric field type liquid crystal display is driven in a normally black mode. In this case, the polarizer is selected so that the voltage becomes θ = 0 ^o when no voltage is applied.

The polarization axis of the polarizing plate 76 and the optical axis of the liquid crystal LC should be configured parallel to each other.

Accordingly, it is sensitive to the disturbance applied to the liquid crystal panel of the initial liquid crystal alignment, because the alignment direction of the initial liquid crystal may be disturbed when the θ = 0 ^o.

That is, as shown in Fig. 3, the liquid crystal LC in the vicinity of the color filter substrate B1 and the upper and lower alignment films 74a and 74b formed in the array substrate B2 is changed in the direction of alignment However, since the liquid crystal molecules themselves oscillate, the alignment direction of the liquid crystals located at the center D of the liquid crystal panel is slightly changed.

Therefore, in this case transverse jeongyehyeong liquid crystal display device because it is not the above-described θ = 0 ^o, the transmittance value is (0) can not become the black color purity not higher This causes a problem that the contrast ratio (contrast ratio) decreased .
