The present invention relates to a liquid crystal display device, and more particularly, to a liquid crystal display device having a pixel array structure for displaying a high resolution image.

In general, a liquid crystal display device injects a liquid crystal material between two substrates having an electrode generating an electric field, and applies an electric potential different from each other to form an electric field to change the arrangement of liquid crystal molecules, thereby transmitting light. It is a device that expresses the image by adjusting.

The liquid crystal display includes a pixel electrode and a plurality of pixels in which red, green, and blue color filters are formed, and each pixel is driven by a signal applied through a wiring to perform a display operation. The wiring includes a scan signal line or a gate line for transmitting a scan signal, an image signal line or a data line for transferring an image signal, and each pixel includes a thin film transistor connected to one gate line and one data line. The image signal transmitted to the pixel electrode formed at the edge is controlled.

In this case, various colors may be displayed by arranging various color filters of red (R), green (G), and blue (B) in each pixel, and as an arrangement method, a color filter of the same color may be used as a unit of pixel columns. Stripe type arranged in a row, Mosaic type arranged in sequence of color filters of red (R), green (G), and blue (B) in the column and row directions, so as to cross unit pixels in the column direction. And a delta type in which the color filters of red (R), green (G), and blue (B) are arranged in a zigzag form and arranged sequentially. In the case of the delta type, when displaying an image of three unit pixels including red (R), green (G), and blue (B) color as one dot, the screen displays a circle or a diagonal line. It has the ability to express well.

However, these conventional pixel arrays are not only inferior in resolution, but also need to drive each unit pixel by using different data driving integrated circuits, which increases the design cost.

Therefore, the technical problem of the present invention is to provide a liquid crystal display device having a pixel array structure that can be designed with a high resolution and low cost.

Another object of the present invention is to provide a liquid crystal display device having excellent visibility characteristics.

In the liquid crystal display according to an aspect of the present invention for achieving the technical problem, blue, red, green pixels are sequentially arranged in a row direction, the blue and green pixels alternately in a column direction A pixel array arranged in such a manner that the red pixels are arranged in the same manner so that the four neighboring blue and green pixels are arranged to face each other with respect to the two neighboring red pixels in two neighboring pixel rows; A gate line disposed in the horizontal direction with respect to the pixel row and transferring a scan signal or a gate signal to the pixel; Data lines arranged to insulate and intersect the gate lines in a vertical direction, and to transfer an image or data signal and to be arranged with respect to the pixel columns; Pixel electrodes formed on the pixels in row and column directions, respectively, to which the data signals are transmitted; And thin film transistors formed in the pixels in row and column directions, respectively, and including a gate electrode connected to the gate line, a source electrode connected to the data line, and a drain electrode connected to the pixel electrode. do.

Here, the two red pixels neighboring each other in the two adjacent pixel rows have different chromas. In particular, the saturation of the red pixel where the blue pixel is located on the left side and the green pixel is located on the right side is lower than that of the red pixel where the green pixel is located on the left side and the blue pixel is located on the right side.

The liquid crystal display of the present invention having such a feature may be driven by a rendering driving technique.

DETAILED DESCRIPTION Embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art may easily practice the present invention. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention.

In the drawings, the thickness of layers, films, panels, regions, etc., are exaggerated for clarity. Like parts are designated by like reference numerals throughout the specification. When a part of a layer, film, region, plate, etc. is said to be "on" another part, this includes not only the other part being "right over" but also another part in the middle. On the contrary, when a part is "just above" another part, there is no other part in the middle.

FIG. 1A illustrates a pixel array structure of a liquid crystal display device according to a first exemplary embodiment of the present invention, and FIG. 1B illustrates a driving example in rendering of a liquid crystal display device having the pixel array structure shown in FIG. 1A. In FIG. 1C, the visibility characteristics generated during the rendering driving of FIG. 1B are illustrated.

As shown in FIG. 1, in the liquid crystal display according to the first embodiment of the present invention, red, blue, and green color filter pixels ‥ R, B, G, ... are arranged in a matrix form. Formed. At this time, red, blue, and green pixels (... R, B, G, ...) are sequentially arranged in the row direction, and red, blue pixels (... R, G, ...) are alternately arranged in the column direction. The blue pixels B are arranged in the same manner, and the red and green pixels R and G are disposed to face each other in a diagonal direction with respect to the blue pixel B with respect to two adjacent rows. .

In the pixel array structure according to the first embodiment of the present invention, the blue pixels are shared together when displaying two dots, and the neighboring blue pixels are transmitted with a data signal by one data driving integrated circuit, and different from each other. Driven by a gate drive integrated circuit. Therefore, by using the pixel array structure, an Ultra Extended Graphics Array (UXGA) resolution can be realized using a Super Video Graphics Array (SVGA) display device. Therefore, the number of expensive data driver integrated circuits can be reduced, thereby minimizing the design cost of the display device.

On the other hand, the conventional liquid crystal display device is a device that implements the color through the additive mixing color, the pixel is composed of red, green, blue which is the primary color of the additive mixture. Each of the red, green, and blue pixels has the same horizontal and vertical lengths, and thus forms a symmetrical structure with respect to the continuous pixels.

However, in the pixel arrangement structure according to the first embodiment of the present invention, since it is asymmetrical with respect to the continuous pixels, it is uncomfortable for human eyes.

In the liquid crystal display according to the first exemplary embodiment in which two blue pixels disposed adjacent to each other in the same column and red and green pixels are disposed to face each other around the same column, in order to improve the resolution degradation due to the reduction of the data lines, As shown in FIG. 1B, the driving of the rendering is performed. In the driving of the rendering, the red and green pixels exhibit the characteristic of driving in the form of dots, while the blue pixels represent the characteristic of driving of the form of lines. As a result, the symmetry of the pixels is broken, and as a result, a luminous defect occurs in which the blue pixels appear in the form of lines.                     

Particularly, the large appearance of the linearity visual defect is caused by the pixel arrangement for rendering. Specifically, since the arrangement of pixels as shown in FIG. 1C has a high degree of cycle per degree based on a spatial frequency of a person's light and shade, the red and green colors in the form of dots When the mixed color and the mixed color of the blue line are implemented at the same time, since yellow, which is a mixed color of red and green, has a higher brightness than blue, as shown in FIG. 1C, a brighter A region and a darker B region are generated. That is, light and dark appear continuously, resulting in light and dark discontinuous bands in the displayed image. As a result, the viewing characteristics for the entire image are deteriorated.

In addition, as shown in FIG. 1A, red, green, and blue pixels are arranged in the same manner as the pixel array structure of a general liquid crystal display, but the shape of the dots formed by the red, green, and blue pixels is not square but rectangular. Structure, in which blue pixels appear long in the longitudinal direction. Therefore, in the pixel areas of a and b, the red and green pixels are symmetrical to each other and appear as mixed colors, but the blue pixels are clearly displayed in a bar shape. In other words, mixed color becomes incomplete symmetry, and the visibility characteristics are deteriorated.

Therefore, in the second embodiment of the present invention described below, the pixel arrangement is appropriately changed in order to improve the luminous characteristic degradation caused by the blue pixels in the pixel arrangement structure according to the first embodiment.

2A illustrates a pixel structure of a liquid crystal display according to a second exemplary embodiment of the present invention, and FIG. 2B illustrates a liquid crystal panel structure in which one pixel region illustrated in FIG. 2A is continuously arranged.

As shown in FIG. 2A and FIG. 2B, in the liquid crystal display according to the second exemplary embodiment of the present invention, the red pixels R are arranged in the same column with respect to two adjacent rows, and the red pixels R are arranged in the same column. ) Are arranged so that the blue and green pixels B and G face each other in the diagonal direction.

Since the pixel array structure is continuously arranged throughout the liquid crystal panel, and the blue and green pixels B and G are disposed to face in a diagonal direction with respect to the red pixel R, the red pixel R is lined. Even if it is formed in a mold, line defects are hardly recognized.

More specifically, the dot formed by the blue, red, and green pixels has a rectangular structure instead of a square shape. In this structure, the red pixels appear long in the long direction, but are arranged in the same column in two adjacent pixel rows. The blue and green pixels are symmetric with each other and appear in mixed colors. However, since the mixed color of the blue and green pixels is cyan, the contrast difference hardly appears in comparison with the color of the adjacent red pixels. That is, conventionally, since red and green pixels arranged in the same column in two adjacent pixel rows appear as yellow, which is a mixed color, the contrast between the color of the blue pixel in the form of a line and the contrast of yellow is large. As a result, the visibility of the blue pixels in the form of bars due to the contrast is poor.

However, according to the second embodiment of the present invention, as described above, since the contrast between cyan and red, which are mixed colors of adjacent blue and green pixels, is not large, the poor visibility characteristic in which the red pixels appear as bars is reduced. do.

It is.

The data line is also connected to the drain electrode 175. In addition, a contact hole 187 of the passivation layer 180 (see FIGS. 3 and 4) for connecting the pixel electrode 190 and the data line is formed on the conductive pattern 177 for the storage capacitor. At the ends of the data line 171, data pads 179 for receiving an image signal from the outside and transmitting the image signal to the data line 171 are connected. In this structure, each pixel column receives an image signal through a data pad connected to the data line 171.

In more detail, the gate wiring is formed on the insulating substrate 100.

And a gate electrode 123 of the thin film transistor connected to the 125 and the gate line 121. Here, the gate wiring has a taper angle, for example, the taper angle may be 30 ° to 90 °.

On the substrate 100, a gate insulating layer 140 made of silicon nitride (SiN _x ) covers the gate wiring.

A semiconductor layer 150 made of a semiconductor such as amorphous silicon is formed in an island shape on the gate insulating layer 140 of the gate electrode 123, and silicide or n-type impurities are doped at a high concentration on the semiconductor layer 150. Resistive contact layers 160 made of a material such as n + hydrogenated amorphous silicon are formed, respectively. Alternatively, the semiconductor layer 150 may be formed along the shape of the data line 171.

In the liquid crystal display according to the second exemplary embodiment of the present invention having the first structure, four blue and green pixels are formed adjacent to both sides of two red pixels R positioned in the same column of adjacent pixel rows. One pixel area, or dot (

Is indicated by). In addition, the liquid crystal display according to the second exemplary embodiment of the present invention may be driven to render in the form as shown in FIG. 1B.

Meanwhile, the thin film transistor substrate of the liquid crystal display according to the second exemplary embodiment of the present invention may have a structure different from that shown in FIGS. 3 and 4.

Sectional drawing of the Ⅶ-Ⅶ 'line.

As shown in FIG. 5, the thin film transistor substrate of the second structure of the liquid crystal display according to the second exemplary embodiment of the present invention is different from the first structure in that the semiconductor layer constituting the thin film transistor substrate is separated from the data line. Made of the same pattern.

Specifically, the gate wiring including the gate line 121, the gate pad 125, and the gate electrode 123 is formed similarly to the first structure on the insulating substrate 100. However, unlike the first structure, the storage electrode line 131 is formed on the substrate 100 in parallel with the gate line 121. The storage electrode line 131 overlaps the conductive capacitor conductor 177 connected to the pixel electrode 190, which will be described later, to form a storage capacitor, which improves the charge retention capability of the pixel. The pixel electrode 190 and the gate line, which will be described later, If the holding capacity generated by the overlap of 121 is sufficient, it may not be formed. The same voltage as that of the common electrode of the upper substrate is usually applied to the storage electrode line 131.

The gate insulating layer 140 is formed on the gate lines 121, 125, and 123 and the storage electrode line 131. Semiconductor patterns 152 and 157 formed of a semiconductor such as hydrogenated amorphous silicon are formed on the gate insulating layer 140, and ohmic contact layer patterns are formed on the semiconductor patterns 152 and 157. Here, the gate wiring has a taper angle, for example, the taper angle may be 30 ° to 90 °.                     

Data wirings are formed on the ohmic contact layer patterns 163, 165, and 167. The data line is a thin film transistor which is a branch of the data line 171 formed in the vertical direction, the data pad 179 connected to one end of the data line 171 to receive an image signal from the outside, and the data line 171.

The passivation layer 180 is formed on the data line. Therefore, even a thin thickness does not cause a parasitic capacity problem. The passivation layer 180 has contact holes 181, 189, and 187 exposing the drain electrode 175, the data pad 177, and the conductive pattern 177 for the storage capacitor, and the gate together with the gate insulating layer 140.

As a result, red pixels with low saturation and high brightness are disposed adjacent to the dark blue pixels, and red pixels with high saturation and low brightness are disposed adjacent to the light green pixels and between the upper and lower pixels in two adjacent pixel rows. By minimizing the brightness change and the brightness change between the left and right pixels, the visual defects in which the dark areas appear as bands due to the contrast of the bright and dark areas are reduced.

Meanwhile, in order to configure red pixels having different saturation, in the photoresist process of the liquid crystal display manufacturing process, red pixels having different saturation may be implemented by adjusting the amount of color material added when the red pixel pattern is formed. In addition, other methods may be used to form red pixels having different saturation.
