   BACKGROUND OF THE INVENTION 
   (a) Field of the Invention 
   The present invention relates to a liquid crystal display having wide viewing angle, and more particularly, to a liquid crystal display having a pixel structure for reducing textures. 
   (b) Description of the Related Art 
   In general, a liquid crystal display (LCD) has an upper panel including a common electrode and a plurality of color filters, a lower panel including a plurality of thin film transistors (TFTs) and a plurality of pixel electrodes, and a liquid crystal layer having liquid crystal molecules disposed therebetween. The pixel electrodes and the common electrode are applied with electrical voltages to generate an electric field to vary the orientation of the liquid crystal molecules, thereby controlling the transmittance of light passing through the liquid crystal layer. 
   Conventional LCDs typically have a disadvantage of narrow viewing angle, i.e., view of the LCDs would be difficult at an angle larger than the viewing angle. Various techniques for widening the viewing angle have been developed. One of the techniques is to form apertures or protrusions in the pixel electrodes and the common electrode opposite the pixel electrodes, and to control the tilt directions of liquid crystal molecules by using the fringe field generated by the apertures or the protrusion, thereby providing several domains. 
   A domain preferably has the shape of a long stripe for improving the fringe field effect and the response time, and thus the planar shape of a domain has two long sides and two short sides. 
   However, this conventional LCD is disadvantageous from a first type of texture generated at the short sides of the domain, a second type of texture in the shape of kidney generated at the center of a pixel, and a third type of texture generated at the chamfered corner of the domain adjacent to a repairing connection. Thus, it is desirable to reduce generation of the textures, thereby enhancing the image quality of an LCD.

   Now, a TFT array panel for an LCD according to the first embodiment will be described with reference to  FIGS. 1A and 1D . 
   A gate wire including a gate line  20  and a gate electrode  21  for transmitting scanning signals or gate signals, and a storage electrode wire including a storage electrode line  30  and first to sixth storage electrodes  31 - 36  applied with a reference voltage such as a common voltage are formed on an insulating substrate  10 , preferably made of transparent glass. The gate line  20  extends in a transverse direction and a gate electrode  21  extends upward and downward from the gate line  20 . The storage electrode line  30  is in parallel to the gate line  20 , and the first to sixth storage electrodes  31 - 36  are branches of the storage electrode line  30 . The first storage electrode  31  having an end directly connected to the storage electrode line  30  extends in a longitudinal direction. One end of the second storage electrode  32  extending in the transverse direction is connected to substantially a midpoint of the first storage electrode  31 , while the other end of the second storage electrode  32  is connected to the third storage electrode  33  around a lower midpoint and extending in the longitudinal direction. An upper end of the third storage electrode  33  is bent in an oblique direction toward an upper right side. The fourth storage electrode  34  extends in the transverse direction, and has two ends connected to substantially a midpoint of the third storage electrode  33  and to one end of the fifth storage electrode  35 , respectively. The other end of the fifth storage electrode  35  is connected to an end of the sixth storage electrode  36 , which obliquely extends toward an upper left side. 
   The gate wire and the storage electrode wire are covered with a gate insulating film  40 . A semiconductor layer  50 , preferably made of amorphous silicon, is formed on the gate-insulating layer  40  opposite the gate electrode  21 . Ohmic contact layers  61  and  62 , preferably made of amorphous silicon heavily doped with N-type impurity such as phosphorus, are separately formed on the semiconductor layer  50 . 
   A data wire including a plurality of data lines  70  and a source electrode  71  and a drain electrode  72  for transmitting image signals or data signals and a buffer  73  are formed on the gate insulating layer  40  and the ohmic contact layers  61  and  62 . The plurality of data lines  70  extends in the longitudinal direction, and a pixel area is defined by intersections of two adjacent data lines  70  and two adjacent gate lines  20 . Under the data line  70 , the ohmic contact layer  51  and the semiconductor layer  50  also preferably extend along the data line  70 , as shown in  FIG. 1A . The source electrode  71  and the drain electrode  72  are disposed on the ohmic contact layers  61  and  62 , respectively. The source electrode  71  having a U-shape is a branch of the data line  70  and is separated from the drain electrode  72 , and a portion of the semiconductor layer  50  disposed between the source and the drain electrodes  71  and  72  is exposed. The drain electrode  72  extends in the transverse direction and is obliquely bent near the third storage electrode  33  toward a lower left direction. The buffer  73  having a rectangular shape is disposed on the gate insulating film  40  and separated from the date wire. 
   The gate electrode  21 , the source electrode  71 , and the drain electrode  72  form three terminals of a TFT, which has the portion of the semiconductor layer  50  disposed between the source and the drain electrodes  71  and  72  as a channel layer. The TFT is connected to the gate line  20 , the data line  70 , and the pixel electrode  90 , and transmits the image signals from the data line  70  to the pixel electrode  90  in response to the scanning signals from the gate line  20 . 
   The data wire, the buffer  73 , and the exposed portion of the semiconductor layer  50  are covered with a passivation film  80  having contact holes  81  and  82 , which expose the drain electrode  72  and a portion of the buffer  73 , respectively. 
   A pixel electrode  90  located in the pixel area and having a rectangular shape, and a repairing connection  98  intersecting the gate line  20  are formed on the passivation film  80 . The pixel electrode  90  and the repairing connection  98  are made of transparent conductive material such as ITO (indium tin oxide) and IZO (indium zinc oxide), or opaque conductive material. 
   The pixel electrode  90  is connected to the drain electrode  72  through the contact hole  81  and the repairing connection  98  is connected to the buffer  73  through the contact hole  82 . The repairing connection  98  also extends in the longitudinal direction to overlap the storage electrode line  30  above the buffer  73  and the extended end of the third storage electrode  33  below the buffer  73 . 
   According to an embodiment of the present invention, the pixel electrode  90  is divided into upper, middle, and lower partitions  91 ,  92 , and  93 , which are arranged in the longitudinal direction. The upper and the middle partitions  91  and  92  are connected via first and second connecting members  94  and  95 , and the middle and the lower partitions  92  and  93  are connected via third and fourth connecting members  96  and  97 . The first and the second connecting members  94  and  95  are spaced apart from left and right ends of the fourth storage electrode  34 , respectively. The third connecting member  96  is spaced apart from a left end of the second storage electrode  32 , and the fourth connecting member  97  is located at a right corer of the pixel electrode. The pixel electrode  90  overlaps the storage electrode wire at least in part to form a storage capacitor. 
   The upper partition  91  is in the rectangular shape having four chamfered corners located in the substantially upper half portion of the pixel area, and is directly connected to the drain electrode  72  through the contact hole  81 . The middle and the lower partitions  92  and  93  are also in the rectangular shapes, each having four chamfered corners, and located in the substantially lower half portion of the pixel area. The fourth and the second storage electrodes  34  and  32  are located between the upper and the middle partitions  91  and  92  and between the middle and the lower partitions  92  and  93 , respectively. The upper partition  91  is almost surrounded by the third, the fourth, the fifth, and the sixth storage electrodes  33 ,  34 ,  35 , and  36 . It is preferable that the angles made by the chamfers and the related edges of the partitions  91 - 93  are in the range of about 120 to about 150 degrees to the long sides, and more preferably about 135 degrees. However, near the boundary between the middle and the lower partitions  92  and  93 , the angles are preferably about 135 to about 180 degrees, and more preferably about 150 to about 170 degrees. 
   The upper left corer of the upper partition  91  and the lower left corner of the lower partition  93  are more chamfered than the other corners to prevent a short-circuit between the pixel electrode  90  and the repairing connection  98 , which occupies some areas near the upper left and lower left corners in the pixel area. 
   Next a color filter array panel according to the first embodiment of the present invention will be described with reference to  FIGS. 1B and 1E . 
   A black matrix  200  preferably made of organic material is formed on a transparent insulating substrate  100 , preferably made of glass to define the pixel area. A color filter  300  is formed in the pixel area of the substrate  100 . A common electrode  400  preferably made of transparent conductor is formed on the color filter  300 , and preferably covers the entire surface of the substrate  100 . The common electrode  400  has first to third apertures  410 - 430  The first aperture  410  extending in the longitudinal direction divides the substantially upper half of the pixel area into two parts arranged in the transverse direction, and the second and the third apertures  420  and  430  extending in the transverse direction and arranged in the longitudinal direction divide the substantially lower half of the pixel area into three parts arranged in the longitudinal direction. Both ends of each aperture  410 ,  420  or  430  are gradually enlarged to form substantially isosceles triangles having two chamfered corners. The angles made by the bottom side and both lateral sides of the isosceles triangle are in the range of 30 to 60 degrees, and more preferably 45 degrees. 
     FIG. 1F  shows a modified example of the color filter array panel shown in  FIG. 1E , where the aperture  410  shown in  FIG. 1E  is replaced with a protrusion  412 . That is, a common electrode  400  has no aperture, and the protrusion  412  is formed on the common electrode  400 . The protrusion  412  is preferably made of organic material. 
   According to an embodiment of the present invention, the black matrix can be made of a double-layered structure of Cr/CrO 2 , and the color filter can be formed in the TFT array panel instead. 
   Then, an LCD according to the first embodiment of the present invention will be described with reference to  FIG. 1C . 
   After the TFT array panel of the  FIG. 1A  and the color filter array panel of  FIG. 1B  are assembled, liquid crystal material is injected into the gap between the two panels and vertically aligned, and two polarizers (not shown) are attached to the outer surfaces of the panels so that their polarizing axes are perpendicular to each other, thereby preparing the LCD according to the first embodiment. The angles made by the polarizing axes and the extending direction of the gate line  20  or the data line  30  are about 45 degrees. 
   When the two panels are aligned, the common electrode  400  of the color filter array panel is opposite the pixel electrode  90  of the TFT array panel and generates an electric field along with the pixel electrode  90 . The upper, middle, and lower partitions  91 ,  92 , and  93  of the pixel electrode  90  and the first, second, and third apertures  410 ,  420 , and  430  of the common electrode  400  overlap each other, thereby dividing a pixel region into a number of domains. The pixel region is defined as a portion of the liquid crystal layer between the corresponding pixel areas of both panels. The first aperture  410  extending in the longitudinal direction divides the upper partitions  91  of the pixel electrode  90  into two, left and right domains, and the second and third apertures  420  and  430  extending in the transverse direction divide the middle and the lower partitions  92  and  93  into two, upper and lower domains, respectively. The planar shape of each domain has a long stripe having two long sides, at most two short sides perpendicular to the long sides, and four lateral sides oblique to the long sides. These shapes of the domains are resulted from the chamfers of the upper, middle, and lower partitions  91 ,  92 , and  93  and the triangular ends of the first, second, and third apertures  410 ,  420 , and  430 . The long sides of the domains are parallel to the data lines or the gate lines, and make at an angle of about 45 degrees with the polarizing axes of the polarizers. 
   According to an embodiment of the present invention, the short sides of the domain are not completely removed and the lengths of the oblique sides are determined preferably by considering the misalignment margin and the lengths of the short sides. Because the short sides are shorter than the oblique sides, the force causing the liquid crystal molecules to tilt in the direction parallel to the long sides is less than the force causing the liquid crystal molecules to tilt in the polarizing directions. Complete removal of the short sides of the domain makes the oblique sides longer, thereby reducing the size of the domains, and decreasing aperture ratio and transmittance. 
   Further, texture in the domain formed over the upper partition  91  is also reduced, because the drain electrode  72  extends between the third storage electrode  33  and the pixel electrode  90 , thereby preventing interference by the end of the third storage electrode  33 . Furthermore, texture near the oblique sides of the domains is also reduced by covering the connections of the two storage electrodes  33  and  34  or  34  and  35  with the pixel electrode  90 . 
   An LCD according to another embodiment of the present invention will be described. 
     FIGS. 2A ,  2 B, and  2 C are layout views of a TFT array panel, a color filter array panels and an LCD manufactured by assembling the panels according to the second embodiment of the present invention, respectively. 
   Referring to  FIG. 2A , except for a chamfer shape of the lower left corner in a pixel electrode  90  of a TFT array panels an LCD according to the second embodiment has substantially the same structure as that according to the first embodiment. The second embodiment is different from the first embodiment in that a lower left corner of a lower partition  93  is chamfered in stepwise manner. According to an embodiment of the present invention, the corner includes a first oblique portion  93   a  extending in an oblique direction, a transverse portion  93   b  which is connected to the first oblique portion  93   a  and extends in the transverse direction, and a second oblique portion  93   c  which is connected to the transverse portion  93   b  and extends in the oblique direction. 
   In this embodiment, the transverse portion  93   b  of the lower partition  93  causes the liquid crystal molecules near the corner to be tilted in the main tilt direction, in which the liquid crystal molecules near the long sides tilt. Therefore, texture near the corner is reduced. 
   An LCD according to the third embodiment of the present invention will be described. 
     FIGS. 3A ,  3 B, and  3 C are layout views of a TFT array panel, a color filter array panel, and an LCD manufactured by assembling the panels according to the third embodiment of the present invention, respectively. 
   Referring to  FIG. 3A , except for the position and the shape of two connecting members  96  and  97  connecting middle and lower partitions  92  and  93  of a pixel electrode  90  of the TFT array panel, an LCD according to the third embodiment has substantially the same structure as that according to the second embodiment. The third embodiment is distinguished from the second embodiment in that the connecting member  96  is located at the left edge of the pixel electrode  90  and covers a connection between storage electrodes  32  and  33 . 
   As a modified example of the third embodiment, corners of the middle and the lower partitions  92  and  93  of the pixel electrode  90  adjacent to the connecting member  96  are chamfered.

   The pixel electrode  90  is connected to the drain electrode  72  through the contact hole  81  and the repairing connection  98  is connected to the buffer  73  through the contact hole  82 . The repairing connection  98  also extends in the longitudinal direction to overlap the storage electrode line  30  above the buffer  73  and the extended end of the first storage electrode  31  below the buffer  73 . 
   The pixel electrode  90  includes first to fourth partitions  91 - 94 , which are arranged in the longitudinal direction, divided by three openings  95 - 97  extending toward the left side from the right side. The partitions  91 - 94  are connected to each other near their left edges since the openings  95 - 97  do not completely pass through the pixel electrode  90 . Two openings  95  and  96  extend along the second and the third storage electrodes  32  and  33 , respectively, and the opening  97  extends in the transverse direction toward the left from around the midpoint of the right edge of the pixel electrode  90 . An entrance of the opening  97  is in the shape of a funnel, which becomes widened as approaching to the right edge of the pixel electrode  90 , and a left end of the opening  97  is located near the center of the pixel electrode  90 , which is different from the other openings  95  and  96 . 
   The pixel electrode  90  has upper left, lower left and lower right corners, which are chamfered, and covers substantially all the first and the fourth storage electrodes  31  and  34  extending in the longitudinal direction. That is, both ends of the first storage electrode  31  and portions of the fourth storage electrode  34  near the entrances of the openings  95 - 97  are not covered with the pixel electrode  90 . The first partition  91 , the lowest one among the four partitions  91 - 94 , is directly connected to the drain electrode  72  through the contact hole  81 . It is preferable that oblique edges of the pixel electrode  90  curve at an angle of about 120 to about 150 degrees (or about 30 to about 60 degrees) with the other edges, and more preferably about 135 degrees (or about 45 degrees). 
   Next, a color filter array panel according to the fourth embodiment of the present invention will be described with reference to  FIGS. 4B and 4E . 
   A black matrix  200  preferably made of organic material is formed on a transparent insulating substrate  100  preferably made of glass to define the pixel area. A color filter  300  is formed in the pixel area of the substrate  100 . A common electrode  400  preferably made of transparent conducting material is formed on the color filter  300 , and preferably covers the entire surface of the substrate  100 . The common electrode  400  has lower, middle, and upper apertures  410 ,  420 , and  430 , and most of the lower, middle, and upper apertures  410 ,  420 , and  430  obliquely pass through the pixel area. The lower aperture  410  has a transverse portion  411 , an oblique portion  412 , and a longitudinal portion  413 . The transverse portion  411  extends along the lower edge of the pixel area from the lower right corner of the pixel area. The oblique portion  412  is connected to the transverse portion  411 , obliquely extends toward an upper left side, and reaches the left edge of the pixel area. The longitudinal portion  413  is connected to the oblique portion  412  and extends in the longitudinal direction along the left edge of the pixel area. The middle aperture  420  has a transverse portion  421 , first and second oblique portions  422  and  423 , and first and second longitudinal portions  424  and  425 . The transverse portion  421  extends in the transverse direction parallel to the gate line  20  from substantially a midpoint of the left edge of the pixel area. The first and the second oblique portions  422  and  423  are commonly connected to the transverse portion  421 , obliquely extending toward lower right and upper right directions, respectively, and reach the right edge of the pixel area. The first and the second longitudinal portions  424  and  425  are connected to the first and the second oblique portions, respectively and extend in the lower and upper directions along the right edge of the pixel area, respectively. The upper aperture  430  is substantially symmetrical to the lower aperture  410  with respect to the middle aperture  420 , and has a transverse portion  431 , an oblique portion  432  and a longitudinal portion  433 . The transverse portion  431  extends along the upper edge of the pixel area from the upper right corner of the pixel area. The oblique portion  432  is connected to the transverse portion  431  and obliquely extending toward a lower left direction, and reaches the left edge of the pixel area. The longitudinal portion  433  is connected to the oblique portion  432  and extends in the longitudinal direction along the left edge of the pixel area. 
   According to an embodiment of the present invention, the black matrix can have a double-layered structure of Cr/CrO 2 , and the color filter can be formed in the TFT array panel instead. 
   Then, an LCD according to the fourth embodiment of the present invention will be described with reference to  FIG. 4C . 
   After the TFT array panel of the  FIG. 4A  and the color filter array panel of  FIG. 4B  are assembled, liquid crystal material is injected into the gap between the two panels and vertically aligned, and two polarizers (not shown) are attached to the outer surfaces of the panels so that their polarizing axes are perpendicular to each other, thereby preparing the LCD according to the fourth embodiment. The polarizing axes are parallel to the gate line  20  or the data line  70 . 
   When the two panels are aligned, the common electrode  400  of the color filter array panel is opposite the pixel electrode  90  of the TFT array panel and generates an electric field along with the pixel electrode  90 . The partitions  91 - 94  of the pixel electrode  90  and the apertures  410 ,  420 , and  430  of the common electrode  400  overlap each other, thereby dividing a pixel region into a number of domains. The pixel region is defined as a portion of the liquid crystal layer between the corresponding pixel areas of both panels. The lower and the upper apertures  410  and  430  divide each of the first and the fourth partitions  91  and  94  of the pixel electrode  90  into two obliquely arranged domains. The middle aperture  420  divides each of the second and the third partitions  92  and  93  into two obliquely arranged domains extending, and the opening  97  of the pixel electrode  90  overlaps the middle aperture  420  of the common electrode  400 . The planar shape of each domain has a long stripe having two oblique long sides parallel to each other, and the long sides of each domain curve at an angle of approximately 45 degrees with the polarizing axes of the polarizer. In addition, the long sides are two types, extending toward the upper right direction and the lower right direction. The two types of the tong sides curve at an angle of about 85 to about 95 degrees with each other. These are made by the shapes of the partitions  91 - 94  and the apertures  410 ,  420 , and  430 . 
   According to an embodiment of the present invention, texture is easily removed by modifying the shape of the apertures. In addition, the texture generated at the oblique sides parallel or perpendicular to the polarizing axes is weaker than one generated in a T-shaped pattern since the storage electrodes are covered with the pixel electrode or the apertures. 
   An LCD according to the fifth embodiment of the present invention will be described. 
     FIGS. 5A ,  5 B, and  5 C are layout views of a TFT array panel, a color filter array panel, and an LCD manufactured by assembling the panels according to the fifth embodiment of the present invention, respectively. 
   Referring to  FIG. 5A , except for positions where the partitions  91  and  92  are connected and the partitions  93  and  94  are connected, an LCD according to the fifth embodiment has substantially the same structure as that according to the fourth embodiment. The fifth embodiment is different from the fourth embodiment in that a connecting member  910  connecting the partitions  91  and  92  and a connecting member  920  connecting the partitions  93  and  94  are located at substantially a midpoint of the openings  95  and  96  of the pixel electrode  90 , respectively, and the partitions  91 - 94  are not connected to each other at the left edge of the pixel electrode  90 . 
   In this embodiment, the oblique sides bent in the longitudinal direction at the long sides in the domains adjacent to the connecting members  910  and  920  are shortened thereby reducing texture generated at the oblique sides by the storage electrode wire. 
   The present invention has domains having oblique sides shorter than the short sides to obtain sufficient aperture ratio and prevent textures. In addition, the extended drain electrode covering oblique sides elongated by the repairing connection.
