Abstract:
A liquid crystal display device includes an arrangement of pixels, wherein each of the pixels includes at least three subpixels, wherein the second subpixel is a Red subpixel, in contrast to the traditional Red-Green-Blue subpixel configuration. Further, a signal line is disposed next to each of the subpixels, but a common line is disposed next to a subpixel which is not a Red subpixel. Thus, the second subpixel, which is a Red subpixel, has on both sides thereof signal lines, but lacks a common line next thereto.

Description:
FIELD 
       [0001]    The present application relates to a liquid crystal display (LCD) device, such as for example, an in-plane switching (IPS) LCD device. 
       BACKGROUND 
       [0002]    Generally, an IPS LCD device includes two substrates sandwiching a liquid crystal layer, having an arrangement of repeating pixels. Generally, a LCD display device has a plurality of pixels arranged in a repeating grid-like arrangement, wherein each pixel is defined by a group of individually addressable elements. Each of these elements is called a subpixel. Each subpixel represents a single color region.  FIGS. 9 and 10  show a traditional IPS LCD device  100 .  FIG. 9  is a schematic sectional side view of pixels of the IPS LCD device  100 .  FIG. 10  is a schematic plan view of pixels of the IPS LCD device  100 . The IPS LCD device  100  can have some areas that are brighter than other areas, or look of nonhomogeneous shading as a whole. This property is less than optimal.

     DETAILED DESCRIPTION 
       [0029]    In  FIGS. 9 and 10 , the IPS LCD device  100  has a repeating arrangement of three subpixels, a red (R) subpixel  102 , a green (G) subpixel  104 , and a blue (B) subpixel  106 . Each of the subpixels  102 ,  104 ,  106  is identified by a color filter (e.g., R for red, G for green, and B for blue). These three subpixels  102 ,  104 ,  106  define a pixel  108 . The pixels  108  are arranged along a horizontal direction in a repeating grid-like arrangement. 
         [0030]    Each subpixel  102 ,  104 ,  106  includes a pixel electrode and a common electrode. The common electrode carries a common voltage to each of the subpixels  102 ,  104 ,  106 . The pixel electrode can be individually controlled to have a different voltage from the common electrode. The voltage difference between the pixel electrode and the common electrode creates an electric field for the respective subpixel. This electric field (a.k.a. transverse electric field) is substantially parallel to the substrate in the liquid crystal layer  110 , and thus, the electric field drives the liquid crystals in the respective subpixel to control the transmission of light through the respective subpixel in the LCD device  100 . 
         [0031]    Arranged next to and/or between each of the adjacent subpixels  102 ,  104 ,  106  are common lines  112  (e.g., copper wires for carrying the common voltage) and signal lines  114  (e.g., copper wires for generating a voltage difference between the common electrode and the pixel electrode for each of the subpixels). The common lines  112  and signal lines  114  are arranged to overlap along a plan view as shown in  FIG. 10 .  FIG. 9  shows the common lines  112  disposed closer to the liquid crystal layer  110  than the signal lines  114 . 
         [0032]    It has been found that the configuration described with respect to  FIGS. 9 and 10  can lead to nonhomogeneous shading regions in the IPS LCD device  100 . 
         [0033]    It has been discovered that light transmission  116  from the backlight can be blocked by one of the common lines  112  for some subpixels. That is, the common line  112  reflects the light  116  back (i.e., away from the liquid crystal layer, or towards the rear of the IPS LCD device  100 ). 
         [0034]    However, other light transmissions  118  from the backlight can be reflected by the common line  112  and then the light  118  can be reflected again by the respectively overlapping signal line  114 , and this can lead the light  118  to be directed towards the liquid crystal layer. Because the common line  112  and the signal line  114  are generally made of copper, when the light  118  is reflected towards the liquid crystal layer in the red subpixel  102  region the light  118  can transmit through the red filter R and leak out to the front of the IPS LCD device  100 . 
         [0035]    That is, backlight, which is generally white light, can be reflected by a wire made of copper and the reflected light is a reddish light that includes the red spectrum as the main element (e.g., wavelength). The reddish light is blocked by a non-red color filter. For example, the light  116  can be reflected by an overlapping signal line  114  and the non-red color filter (e.g., Blue (B), Green (G), Yellow (Y), etc.) can block the light  116  from being transmitted through the non-red color filter. However, the reddish light passes through the red color filter R. 
         [0036]    The alignments between the common lines  112  and the signal lines  114  differ depending on the area in a display region. The property of passing through the red color filter by the reddish light is nonhomogeneous due to unevenness of the display region caused during a manufacturing process of the display. Thus, the light blockage (e.g., light  116 ) and light leakage (e.g., light  118 ) can occur differently in regions of the IPS LCD device  100 . That is, the IPS LCD device  100  can have some areas that are brighter than other areas, or look of nonhomogeneous shading as a whole. This property is less than optimal. 
         [0037]      FIG. 1  is a schematic sectional side view of pixels of a LCD device  200  according to an embodiment. An embodiment of the LCD device  200  is an IPS LCD device. The LCD device  200  includes a first substrate  202  on a display surface side  204 , a second substrate  206  on a rear surface side  208 , and a liquid crystal layer  210  interposed between the first substrate  202  and the second substrate  206 . 
         [0038]    The first substrate  202  is a substrate assembly including a black matrix BM, a color filter CF, an overcoat layer OC and a second alignment layer AL 2  stacked on a second glass substrate GS 2 . 
         [0039]    The LCD device  200  includes at least two adjacent common lines  212 ,  214  arranged along a first direction on the second substrate  206 . That is, the second substrate  206  is a substrate assembly including a gate line (not shown), a gate insulator film GAL, a thin film transistor (TFT) including a semiconductor layer, a drain electrode and a source electrode, a first passivation film PAS 1 , an organic passivation layer OPAS, a common electrode CIT, common lines  212 ,  214 , a second passivation film PAS 2 , a pixel electrode PIT, an upper passive layer UPAS, and a first alignment layer AL 1  being stacked on a first glass substrate GS 1 . 
         [0040]    The LCD device  200  includes a repeating arrangement of pixels  216 . Each of the pixels  216  includes at least three subpixels, a first subpixel  218 , a second subpixel  220 , and a third subpixel  222 . Each of the subpixels  218 ,  220 ,  222  can be identified a respective color filter. For example, the first subpixel  218  can be either blue or green. The second subpixel  220  is red. For example, the third subpixel  222  can be either blue or green. The three subpixels  218 ,  220 ,  222  are arranged along a direction that is different from the direction the common lines  212 ,  214  are extended length-wise. 
         [0041]    The signal lines  224 ,  226 ,  228 ,  230  are arranged next to and/or between the subpixels  218 ,  220 ,  222 . The signal line  224  is vertically in line with the common line  212 , whereas the signal line  230  is vertically in line with the common line  214 . That is, the signal line  224  overlaps with the common line  212  when viewed from the display surface side  204  to the rear surface side  208 . Further, the signal line  230  overlaps with the common line  214  when viewed from the display surface side  204  to the rear surface side  208 . However, there are no common lines that overlap with the signal lines  226 ,  228  next to the second subpixel  220  when viewed from the display surface side  204  to the rear surface side  208 . Accordingly, light from the backlight (from the rear surface side  208 ) cannot be reflected back towards the signal lines  226 ,  228 . This may reduce the possibility of light being reflected towards the display surface side  204  by the signal lines  226 ,  228 . That is, the LCD device  200  can have homogeneous shading as a whole. 
         [0042]    A common voltage can still be provided to the second subpixel  220  from one of the common lines  212 ,  214 , so that an electric field can still be generated in the liquid crystal layer  210  of the second subpixel  220 . This electric field is substantially parallel to the substrate in the liquid crystal layer  210 , and thus, the electric field drives the liquid crystals in the subpixel  220  to control the transmission of light through the subpixel  220 . 
         [0043]    The gate line is formed of, for example, a metallic material such as aluminum (Al) and/or copper (Cu). The thickness of the gate line is, for example, 100 to 300 nm. On the upper portion of the gate line, the gate insulator film GAL is formed. As the gate insulting film GAL, for example, a silicon nitride SiN formed with a plasma chemical vapor deposition method (CVD) can be used. The gate insulator film GAL may also be formed of silicon dioxide SiO 2  or alumina Al 2 O 3 . 
         [0044]    The semiconductor layer is processed into, for example, the shape of an island and is arranged above the gate line. As the semiconductor layer material of the semiconductor layer, for example, a combination of a silicon nitride SiN and amorphous silicon a-Si, a combination of silicon dioxide SiO 2  and an oxide semiconductor or a low-temperature poly-silicon LTPS can be used. For example, as the oxide semiconductor, an oxide of indium-gallium-zinc or the like can be used. 
         [0045]    At the end portions of the semiconductor layer, the signal lines  224 ,  226 ,  228 ,  230  and the source electrode are formed. As the signal lines  224 ,  226 ,  228 ,  230  and the source electrode, for example, as described later, a low-resistant metallic material can be used, such as for example, aluminum Al or copper Cu. On the signal lines  224 ,  226 ,  228 ,  230  and the source electrode, the first passivation film PAS 1  is formed. As the first passivation film PAS 1 , for example, a silicon nitride SiN or silicon dioxide SiO 2  can be used. The first passivation film PAS 1  has a thickness of, for example, 200 to 400 nm. 
         [0046]    The organic passivation layer OPAS is formed of, for example, a photosensitive resist material such as acrylic. Its thickness is, for example, 3 micro meters, and it is formed to be thicker than the other inorganic insulating layers. 
         [0047]    There are overlaps of electrode portions on the opposed faces of the common electrode CIT and the pixel electrode PIT sandwiching the second passivation film PAS 2  therebetween, and openings (slits) are formed in the pixel electrode PIT. The first alignment layer AL 1  for aligning liquid crystal molecules of the liquid crystal layer  210  is formed between the liquid crystal layer  210  and the electrode layer of the common electrode CIT and the pixel electrode PIT. 
         [0048]    The pixel electrode PIT and the common electrode CIT constitute an electrode portion for forming the fringe electric field in the liquid crystal layer  210 . 
         [0049]    The transparent pixel electrode PIT is connected to the source electrode vie a through-hole (not shown) formed in the first passivation film PAS 1 , the organic passivation layer OPAS and the second passivation film PAS 2 . With respect to the supply of the data voltage to the transparent pixel electrode PIT, when the on-voltage is applied to the gate line, the resistance of the semiconductor layer is lowered, and the data voltage is transmitted from one or more of the signal lines  224 ,  226 ,  228 ,  230  through the source electrode to the transparent pixel electrode PIT. By applying a voltage to the pixel electrode PIT, a predetermined potential difference corresponding to the modulation of transmittance of the liquid crystal of a pixel is imparted between the pixel electrode PIT and the common electrode CIT. The fringe electric field is generated in the vicinity of the openings in the pixel electrode PIT in the liquid crystal layer  210  by the potential difference, so that an alignment state of the liquid crystal molecules in the liquid crystal layer  210  is controlled so as to rotate the liquid crystal molecules in the substrate in-plane direction. 
         [0050]    The LCD device  200  has common lines  212 ,  214  positioned closer to the liquid crystal layer  210  than the signal lines  224 ,  226 ,  228 ,  230 . Alternatively, the LCD device  300  shown in  FIG. 2  has the signal lines  224 ,  226 ,  228 ,  230  positioned closer to the liquid crystal layer  210  than the common lines  212 ,  214 . Otherwise, the elements of the LCD device  300  shown in  FIG. 2  are same or similar to those of the LCD device  200  shown in  FIG. 1 . The LCD device  300  prevents the light from the backlight (from the rear surface side  208 ) from being reflected towards the display surface side  204  even when the light is reflected by the signal lines  226 ,  228 , because there are no common lines that are vertically beneath the signal lines  226 ,  228  to reflect the reflected light form the signal lines  226 ,  228 . This may reduce the possibility of light being reflected towards the display surface side  204  even when the light is reflected by the signal lines  226 ,  228 . That is, the LCD device  200  can have homogeneous shading as a whole. 
         [0051]    In comparison with  FIG. 1 , the relationship in position of the signal lines  224 ,  226 ,  228 ,  230  and the common lines  212 ,  214  is opposite. The signal lines  224 ,  226 ,  228 ,  230  are provided closer to the liquid crystal layer  210  than the common lines  212 ,  214 . A third passivation layer PAS 3  is formed between the common electrode CIT and the organic passivation layer OPAS. The third passivation layer PAS 3  covers the signal lines  224 ,  226 ,  228 ,  230  formed on the organic passivation layer OPAS. 
         [0052]      FIG. 3  is a schematic plan view of pixels of a LCD device  400  (similar to  200  in  FIG. 1 or 300  in  FIG. 2 ). The signal lines  224 ,  226 ,  228 ,  230  are arranged next to and/or between the subpixels  218 ,  220 ,  222 . The signal line  224  overlaps with the common line  212 . Further, the signal line  230  overlaps with the common line  214 . However, there are no common lines that overlap with the signal lines  226 ,  228  next to the second subpixel  220 . In this embodiment, the second subpixel  220  is a red subpixel. 
         [0053]      FIG. 4  is a schematic plan view of pixels of a LCD device  500  according to another embodiment. Like the LCD device  400  shown in  FIG. 3 , the signal lines  224 ,  226 ,  228 ,  230  are arranged next to and/or between the subpixels  218 ,  220 ,  222 . The signal line  224  overlaps with the common line  212 . Further, the signal line  230  overlaps with the common line  214 . Further, there are no common lines that overlap with the signal lines  226 ,  228  next to the second subpixel  220 . The second subpixel  220  is a red subpixel. Further, the LCD device  500  includes another common line  502  which connects the two adjacent common lines  212 ,  214 . This arrangement allows for improved delivery of common voltage common electrodes formed in to the second subpixel  220 . For example, the another common line  502  can run along a direction that is substantially the same as the direction of arrangement of the three subpixels  218 ,  220 ,  222 . 
         [0054]      FIG. 5  is a schematic sectional side view of pixels of a LCD device  600  according to another embodiment. The LCD device  600  can also be an IPS LCD device. The LCD device  600  includes a first substrate  602  on a display surface side  604 , a second substrate  606  on a rear surface side  608 , and a liquid crystal layer  610  interposed between the first substrate  602  and the second substrate  606 . The LCD device  600  also includes at least three sequentially arranged common lines  612 ,  614 ,  616  along a first direction on the second substrate  606 . The LCD device  600  includes a repeating arrangement of pixels  618 . Each of the pixels  618  includes at least four subpixels, a first subpixel  620 , a second subpixel  622 , a third subpixel  624 , and a fourth subpixel  626 . At least three of the four subpixels  620 ,  622 ,  624  can be identified a respective color filter. For example, the first subpixel  620  can be either blue or green. The second subpixel  622  is red. For example, the third subpixel  624  can be either blue or green. The fourth subpixel  626  can be identified by a yellow color filter (thus being a yellow subpixel). The four subpixels  620 ,  622 ,  624 ,  626  are arranged along a direction that is different from the direction the common lines  612 ,  614 ,  616  are extended length-wise. 
         [0055]    The signal lines  628 ,  630 ,  632 ,  634 ,  636  are arranged next to and/or between the subpixels  620 ,  622 ,  624 ,  626 . The signal line  628  is vertically in line with the common line  612 . The signal line  634  is vertically in line with the common line  614 . The signal line  636  is vertically in line with the common line  616 . 
         [0056]    That is, the signal line  628  overlaps with the common line  612  when viewed from the display surface side  604  to the rear surface side  608 . Further, the signal line  634  overlaps with the common line  614  when viewed from the display surface side  604  to the rear surface side  608 . Furthermore, the signal line  636  overlaps with the common line  616  when viewed from the display surface side  604  to the rear surface side  608 . 
         [0057]    However, there are no common lines that overlap with the signal lines  630 ,  632  next to the second subpixel  622 . Accordingly, light from the backlight (from the rear surface side  608 ) cannot be reflected back towards the signal lines  630 ,  632 . This may reduce the possibility of light being reflected towards the display surface side  604  by the signal lines  630 ,  632 . That is, the LCD device  600  can have homogeneous shading as a whole. 
         [0058]    The LCD device  600  has common lines  612 ,  614 ,  616  positioned closer to the liquid crystal layer  610  than the signal lines  628 ,  630 ,  632 ,  634 ,  636 . Alternatively, the LCD device  700  shown in  FIG. 6  has the signal lines  628 ,  630 ,  632 ,  634 ,  636  positioned closer to the liquid crystal layer  610  than the common lines  612 ,  614 ,  616 . Otherwise, the elements of the LCD device  700  shown in  FIG. 6  are same or similar to those of the LCD device  600  shown in  FIG. 5 . The LCD device  700  prevents the light from the backlight (from the rear surface side  208 ) from being reflected towards the display surface side  604  even when the light is reflected by the signal lines  630 ,  632 , because there are no common lines that are vertically beneath the signal lines  630 ,  632  to reflect the reflected light form the signal lines  630 ,  632 . This may reduce the possibility of light being reflected towards the display surface side  604  even when the light is reflected by the signal lines  630 ,  632 . That is, the LCD device  700  can have homogeneous shading as a whole. 
         [0059]      FIG. 7  is a schematic plan view of pixels of a LCD device  800  (similar to  600  in  FIG. 5 or 700  in  FIG. 6 ). The signal lines  628 ,  630 ,  632 ,  634 ,  636  are arranged next to and/or between the subpixels  620 ,  622 ,  624 ,  626 . In plan view, the signal line  628  overlaps with the common line  612 , the signal line  634  overlaps with the common line  614 , and the signal line  636  overlaps with the common line  616 . 
         [0060]    However, there are no common lines that overlap with the signal lines  630 ,  632  next to the second subpixel  622 . In this embodiment, the second subpixel  622  is a red subpixel. 
         [0061]      FIG. 8  is a schematic plan view of pixels of a LCD device  900  according to another embodiment. Like the LCD device  800  shown in  FIG. 7 , the signal lines  628 ,  630 ,  632 ,  634 ,  636  are arranged next to and/or between the subpixels  620 ,  622 ,  624 ,  626 . In plan view, the signal line  628  overlaps with the common line  612 , the signal line  634  overlaps with the common line  614 , and the signal line  636  overlaps with the common line  616 . Further, the LCD device  900  includes another common line  902  which connects the adjacent common lines  612 ,  614 . The common line  902  can also connect to the common line  616 . This arrangement allows for improved delivery of common voltage to a common electrode formed in the second subpixel  622 . For example, the another common line  902  can run along a direction that is substantially the same as the direction of arrangement of the four subpixels  620 ,  622 ,  624 ,  626 .
