CROSS-REFERENCE TO RELATED APPLICATION 
       [0001]    This application claims priority under 35 U.S.C. §119 to Korean Patent Application No. 2011-66462, filed on Jul. 5, 2011 in the Korean Intellectual Property Office (KIPO), the contents of which are herein incorporated by reference in their entirety. 
       BACKGROUND OF THE INVENTION 
       [0002]    1. Field of the Invention 
         [0003]    Example embodiments of the present invention relate to a display substrate and a method of repairing the display substrate. More particularly, example embodiments of the present invention relate to a display substrate having a high light transmission rate and a method of repairing the display substrate. 
         [0004]    2. Description of the Related Art 
         [0005]    Generally, a display apparatus includes a display panel, a backlight assembly, and a receiving container. The display panel includes a first display substrate and a second display substrate, and the backlight assembly includes an internal light source. The display panel transmits light provided from the light source to display an image. 
         [0006]    Recently, a transparent display apparatus displaying an image using an external light source such as natural or artificial light has been used; the transparent display apparatus may not have a backlight assembly that includes an internal light source. If a full-cover color filter entirely covering a pixel transmitting the light is used in the transparent display apparatus, the transparent display apparatus may be ineffective for transparently displaying the image. 
         [0007]    Therefore, in the display panel of the transparent display apparatus, a partial-cover color filter partially covering the pixel is used, so that the transparent display apparatus may transparently display the image in a more effective manner. 
         [0008]    Typically, the partial-cover color filter may be misaligned with respect to the pixel in a longitudinal direction of the pixel, so that a transmission rate is increased and a color reproducibility is decreased, or the transmission rate is decreased and the color reproducibility is increased. For example, when the partial-cover color filter is misaligned with respect to the pixel to increase an area covered by the partial-cover color filter, the transmission rate may be decreased and the color reproducibility may be increased. On the other hand, when the partial-cover color filter is misaligned with respect to the pixel to decrease the area covered by the partial-cover color filter, the transmission rate may be increased and the color reproducibility may be decreased. Thus, the transmission rate and the color reproducibility may be variable, unstable, and inconsistent. 
       SUMMARY OF THE INVENTION

         [0010]    Example embodiments of the present invention also provide a method of repairing the display substrate. 
         [0011]    According to an example embodiment of the present invention, a display substrate includes a first blocking pattern and a first color filter pattern.

         [0021]    In an example embodiment, the display substrate may further include a color connecting pattern. The color connecting pattern may be disposed between the first color filter pattern and a second color filter pattern adjacent to in the first color filter pattern along the first direction, the color connecting pattern connecting the first color filter pattern with the second color filter pattern and overlapping the first blocking pattern. 
         [0022]    In an example embodiment, the first and second color filter patterns and the color connecting patterns disposed between the color filter pattern may define an opening.

The color filter pattern may overlap the first and third portions of the first pixel area. The second blocking pattern may overlap the first and third portions of the second pixel area. 
         [0028]    In an example embodiment, the plurality of pixel areas may be arranged along a first direction and along a second direction crossing the first direction, and each pixel may include a first portion, a second portion, and a third portion disposed in order along the first direction. The color filter pattern may overlap the second portion of the first pixel area. The second blocking pattern may overlap the second portions of the second pixel area. 
         [0029]    In an example embodiment, the plurality of pixel areas may be arranged along a first direction and along a second direction crossing the first direction, and each pixel may include a first portion and a second portion disposed in order along the first direction. The color filter pattern may overlap one of the first portion and the second portion of the first pixel area.

         [0030]    In an example embodiment, the second blocking pattern may have a first length along the first direction, and the first length may be smaller than a length of the pixel area. The second blocking pattern may have a first width along the second direction, and the first width may be larger than or equal to width of the pixel area. 
         [0031]    According to an example embodiment of the present invention, a method of repairing a display substrate is provided. In the method, a first laser is irradiated to a color filter pattern that partially overlaps a pixel area to remove at least a portion of the color filter pattern, the pixel area being defined by a first blocking pattern on a base substrate. A second laser is irradiated to a portion of the first blocking pattern that is adjacent to the color filter pattern to form a second blocking pattern in at least a portion of the pixel area, the second blocking pattern extending from the first blocking pattern. 
         [0032]    In an example embodiment, the pixel area may include a first portion, a second portion, and a third portion in order along the first direction, the second portion being positioned between the first portion and the third portion. The first laser may be irradiated to one or more portions of the color filter pattern that correspond to the first and third portions of the pixel area. 
         [0033]    In an example embodiment, the pixel area may include a first portion, a second portion, and a third portion in order along the first direction. The first laser may be irradiated to one or more portions of the color filter pattern that correspond to the second portion of the pixel area. 
         [0034]    In an example embodiment, the pixel area may include a first portion and a second portion in order along the first direction. The first laser may be irradiated to one or more portions of the color filter pattern that correspond to one of the first portion and the second portion of the pixel area. 
         [0035]    According to an example embodiment of the present invention, a display panel includes a first display substrate and a second display substrate. The first display substrate includes a first blocking pattern defining a plurality of pixel areas on a first base substrate, the plurality of pixel areas including a first pixel area and a second pixel area disposed adjacent to each other along a first direction. The second display substrate includes a second base substrate opposite to the first display substrate, a switching element disposed on the second base substrate and corresponding to the first pixel area, and a color filter pattern disposed on the switching element and partially overlapping each of the first pixel area and the second pixel area. 
         [0036]    In an example embodiment, each pixel area of the plurality of pixel areas may include a first portion, a second portion, and a third portion in order along the first direction. The color filter pattern may overlap the third portion of the first pixel area, the first portion of the second pixel area, and a portion of the first blocking pattern that is disposed between the third portion of the first pixel area and the first portion of the second pixel area. The first direction may be a longitudinal direction of the first pixel area. 
         [0037]    In an example embodiment, the second display substrate may further include a second blocking pattern extending from the first blocking pattern and partially overlapping the first pixel area. 
         [0038]    According to an example embodiment of the present invention, a display panel includes a first display substrate and a second display substrate. The first display substrate includes a first base substrate. The second display substrate includes a second base substrate opposite to the first display substrate, a switching element disposed on the second base substrate, and a first blocking pattern disposed on the switching element and defining a plurality of pixel areas. The plurality of pixel areas may include a first pixel area and a second pixel area adjacent to each other along a first direction. The second display substrate may further include a color filter pattern disposed on the switching element and the first blocking pattern and partially overlapping each of the first pixel area and the second pixel area. 
         [0039]    In an example embodiment, the second display substrate may further include a second blocking pattern extending from the first blocking pattern and partially overlapping the second pixel area. 
         [0040]    According to the present invention, even if a set of color filter patterns is misaligned with respect to a set of pixel areas, the total area in which the set of color filter patterns overlaps the set of pixel areas may remain substantially constant and substantially consistent. Therefore, a display panel that includes the set of color filter patterns and the set of pixel areas may have improved fault tolerance against misalignment. Advantageously, a transmission rate and a color reproducibility of the display panel may remain substantially constant and/or substantially consistent. 
         [0041]    A color filter pattern entirely covers a first blocking pattern between pixel areas adjacent to each other in a longitudinal direction, so that an upper surface of the first blocking pattern may be planarized. Advantageously, the display panel may have a substantially constant liquid crystal margin over the color filter pattern on the first blocking pattern. 
         [0042]    In one or more embodiments, the color filter pattern may not cover the portion of the first blocking pattern that is disposed between pixel areas adjacent to each other along the longitudinal direction, so that the upper surface of the first blocking pattern may be planarized. Thus, the display panel may have a substantially constant liquid crystal margin over the first blocking pattern. 
         [0043]    The color filter pattern partially overlaps a pixel area. The pixel area may be partially repaired using a nearby blocking pattern.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0071]    Hereinafter, the present invention will be explained in detail with reference to the accompanying drawings. 
         [0072]      FIG. 1  is a plan view illustrating a first display substrate according to an example embodiment of the present invention.  FIG. 2  is a cross-sectional view illustrating a display panel including the first display substrate taken along a line I-I′ of  FIG. 1 . 
         [0073]    Referring to  FIG. 1  to  FIG. 2 , a display panel  1000  includes a first display substrate  100 , a second display substrate  200  facing the first display substrate  100 , and a liquid crystal layer  300  disposed between the first display substrate  100  and the second display substrate  200 . The display panel  1000  may be divided into a plurality of pixel areas PAs (including a pixel area PA 1  and a pixel area PA 2 ) and a blocking area BA defining (and positioned between) the pixel areas PAs. External light, including at least one of natural light and artificial light, may be transmitted through the pixel areas PAs of the display panel  1000 , and the external light may be blocked by the blocking area BA of the display panel  1000 . 
         [0074]    The first display substrate  100  includes a first base substrate  110 , a first blocking pattern  120 , and a color filter pattern  130 . 
         [0075]    The first blocking pattern  120  is disposed in the blocking area BA on the first base substrate  110 . Thus, the first blocking pattern  120  may define (and may be disposed between) the plurality of pixel areas PAs on the first base substrate  110 . A pixel area PA is surrounded by the blocking area BA and may have a particular shape. For example, the pixel area PA may have a quadrilateral shape having a chamfered corner. The first blocking pattern  120  may include an organic material having a black color or a gray color. 
         [0076]    As an example, the pixel area PA may have a rectangular shape in the plan view of the first display substrate  100 . The pixel area PA may have the rectangular shape extending in a first direction D 1  and extending in a second direction D 2  crossing the first direction D 1 . The second direction D 2  is substantially perpendicular to the first direction D 1 . The pixel area PA may have a first length L 1  extending in the first direction D 1  and a first width W 1  extending in the second direction D 2 . The first direction D 1  is a longitudinal direction of the pixel area PA, and the second direction D 2  is a latitudinal direction of the pixel area PA. The first length L 1  may be about three times larger than the first width W 1  or about three times the first width W 1 . The pixel areas PAs may be spaced apart from each other by the blocking area BA and may be arranged in a matrix. 
         [0077]    The first blocking pattern  120  blocks the external light transmitted through the first base substrate  110  between pixel areas PAs adjacent to each other, so that the light transmitted through the pixel areas PAs may not interfere with each other. 
         [0078]    The color filter pattern  130  may be one of a red color filter pattern R, a green color filter pattern G, and a blue color filter pattern B. The color filter pattern  130  may include an organic material having one of a red color, a green color and a blue color. The red, green and blue color filter patterns R, G and B are alternately arranged. The red color filter pattern R converts the external light into red color light, the green color filter pattern G converts the external light into green color light, and the blue color filter pattern B converts the external light into blue color light. 
         [0079]    The color filter pattern  130  has a rectangular shape in the plan view of the first display substrate  100 . The color filter pattern  130  may have the rectangular shape extending in the first direction D 1  and extending in the second direction D 2 . The color filter pattern  130  may have a second length L 2  extending in the first direction D 1  and a second width W 2  extending in the second direction D 2 . The color filter pattern  130  overlaps the pixel area PA in the first direction D 1 , so that an overlapping area between the color filter pattern  130  and the pixel area PA is defined. If the first length L 1  remains constant, as the second length L 2  increases, the color reproducibility may increase. On the other hand, as the second length L 2  decreases, the light transmission rate may increase. The second width W 2  is larger than the first width W 1 , so that the color filter pattern  130  may have at least one of a left overlay margin and a right overlay margin in the second direction D 2 . 
         [0080]      FIGS. 3A and 3B  are partial plan views illustrating the first display substrate for explaining the transmission rate and color production of a color filter pattern of  FIG. 1 . 
         [0081]    Referring to  FIG. 3A  and  FIG. 3B , a color filter pattern partially overlaps each of two pixel areas PAs adjacent to each other along the first direction D 1 . 
         [0082]    For example, the first display substrate  100  includes first and second pixel areas PA 1  and PA 2  that are arranged along the first direction D 1  and disposed adjacent to each other. The first display  100  further includes first, second and third color filter patters  131 ,  132 , and  133  that are arranged along the first direction D 1  and disposed adjacent to each other. The first pixel area PA 1  may include a first portion P 1 , a second portion P 2 , and a third portion P 3  disposed in order along the first direction D 1 . The second pixel area PA 2  may include a fourth portion P 4 , a fifth portion P 5 , and a sixth portion P 6  disposed in order along the first direction D 1 . 
         [0083]    The first color filter pattern  131  extends in the first direction D 1  and overlaps the first portion P 1  of the first pixel area PA 1 . 
         [0084]    The second color filter patter  132  is spaced apart from the first color filter pattern  131  along the first direction D 1 . The second color filter pattern  132  partially overlaps each of the first and second pixel areas PA 1  and PA 2  that are adjacent to each other. The second color filter pattern  132  extends from the third portion P 3  associated with the first pixel area PA 1  to the fourth portion P 4  associated with the second pixel area PA 2 . Thus, the second color filter patter  132  overlaps the third portion P 3  associated with the first pixel area PA 1 , the fourth portion P 4  associated with the second pixel area PA 2 , and the first blocking pattern  120  disposed between the first pixel area PA 1  and the second pixel area PA 2 . 
         [0085]    The third color filter patter  133  is spaced apart from the second color filter pattern  132 . The third color filter pattern  133  overlaps the sixth portion P 6  associated with the second pixel area PA 2 . 
         [0086]    When the first to the third color filter patterns  131 ,  132 , and  133  are formed, the first to the third color filter patterns  131 ,  132 , and  133  may be aligned or misaligned with respect to the pixel areas PA 1  and PA 2  along the first direction D 1 . According to an example embodiment, although the first to the third color filter patterns  131 ,  132 , and  133  may move in the first direction D 1  to be misaligned with respect to the first and second pixel areas PA 1  and PA 2 , the sum (or total size) of overlapping areas OAs in which the first to the third color filter patterns  131 ,  132 , and  133  overlap the first and the second pixel areas PA 1  and PA 2  may remain substantially constant and/or substantially consistent for different pixel areas. 
         [0087]    For example, when the first to the third color filter patterns  131 ,  132 , and  133  are aligned with (e.g., disposed symmetrically with respect to) the pixel areas PA 1  and PA 2  along the first direction D 1 , wherein “aligned” means that the color filter patterns are positioned with respect to the pixel areas according to a predefined configuration of the first display substrate, the first color filter pattern  131  may overlap the first pixel area PA 1  at the first portion P 1  defined by an upper side of the first pixel PA 1  and a first (imaginary) reference line RL 1  (which is aligned with a lower edge of the first color filter pattern  131 ), and the second color filter pattern  132  may overlap the first pixel area PA 1  at the third portion P 3  defined by a lower side of the first pixel PA 1  and a second (imaginary) reference line RL 2  (which is aligned with an upper edge of the second color filter pattern  132  and is spaced apart from the first reference lien RL 1  by the second portion P 2 ). Thus, the first portion P 1  and the third portion P 3  display color light as overlapping areas OAs to increase color reproducibility, and the second portion P 2  displays white light as a non-overlapping area NOA to increase the light transmission rate. Since the color filters  131  and  132  are disposed symmetrically with respect to the first pixel PA 1 , the overlapping areas OAs may have the same size. The arrangements of portions P 4 , P 5 , and P 6  are similar to the arrangements of portions P 1 , P 2 , and P 3 , respectively. 
         [0088]    On the other hand, when the first to the third color filter patterns  131 ,  132 , and  133  are misaligned with (e.g., disposed asymmetrically with respect to) the pixel areas PA 1  and PA 2  along the first direction D 1 , the first color filter pattern  131  may overlap the first pixel area PA 1  at another first portion P 1 ′ defined by at least the upper side of the first pixel PA 1  and a third (imaginary) reference line RL 3  moved from the first reference line RL 1  in the first direction D 1 , and the second color filter pattern  132  may overlap the first pixel area PA 1  by another third portion P 3 ′ defined by at least the lower side of the first pixel PA 1  and a fourth (imaginary) reference line RL 4  moved from the second reference line RL 2  in the first direction D 1 . Thus, the first portion P 1 ′ and the third portion P 3 ′ display the color light as another set of overlapping areas OA&#39;s to increase color reproducibility, and the second portion P 2 ′ displays the white light as another non-overlapping area NOA′ to increase the light transmission rate. Since the color filters  131  and  132  are disposed asymmetrically with respect to the first pixel PA 1 , the overlapping areas OA&#39;s may have different sizes. The arrangements of portions P 4 ′, P 5 ′, and P 6 ′ are similar to the arrangements of portions P 1 ′, P 2 ′, and P 3 ′, respectively. 
         [0089]    The first to the third color filter patterns  131 ,  132 , and  133  simultaneously move in the first direction D 1 , so that a total area of the overlapping areas OAs defined by the first and the second reference line RL 1  and RL 2  is substantially equal to a total area of the overlapping areas OAs&#39; defined by the third and the fourth reference lines RL 3  and RL 4 . 
         [0090]    Referring to  FIG. 1  and  FIG. 2 , the first display substrate  100  may further include an over-coating layer  140 , a common electrode layer  150 , and a column spacer  160 . The over-coating layer  140  may be an organic layer. The column spacer  160  is disposed over the color filter pattern  130  and overlapping the first blocking pattern  120 . The color filter pattern  130  is formed to completely cover the first blocking pattern  120  between two pixel areas PAs adjacent to each other in the first direction D 1 . The color filter pattern  130  may be relatively planarized on the first blocking pattern  120 . Thus, the display panel  1000  may have a substantially constant liquid crystal margin at or near the position of the column spacer  160  over the color filter pattern  130  overlapping the first blocking pattern  120 . 
         [0091]    Alternatively or additionally, the column spacer  160  may be included in the second display substrate  200 . 
         [0092]    The second display substrate  200  includes a second base substrate  210 , a switching element  220 , a protecting layer  230 , and a pixel electrode P 3 . The switching element  220  and the pixel electrode PE are formed in the pixel area PA (e.g., PA 1  or PA 2 ). The switching element  220  includes a gate electrode, a source electrode, and a drain electrode, and the pixel electrode PE is electrically connected to the drain electrode of the switching element  220 . The protecting layer  230  may be an organic layer or an inorganic layer. 
         [0093]    According to the examples of  FIGS. 1-3B , although the first to the third color filter patterns  131 ,  132 , and  133  may be aligned or misaligned with (e.g., disposed asymmetrically with respect to) the pixel areas PA 1  and PA 2  along the first direction D 1 , the color reproducibility and the transmission rate of the display panel  1000  including the first display substrate  100  may remain substantially constant and/or substantially consistent for different pixel areas. 
         [0094]      FIG. 4  is a plan view illustrating a first display substrate according to an example embodiment of the present invention.  FIG. 5  is a cross-sectional view illustrating a display panel including the first display substrate taken along a line II-II′ of  FIG. 4 .  FIGS. 6A and 6B  are partial plan views illustrating the first display substrate to explain a transmission rate and a color production of a color filter pattern of  FIG. 4 . 
         [0095]    A first display substrate according to the present example embodiment may be substantially similar to or the same as the first display substrate according to the examples of  FIG. 1  to  FIG. 3B  except, for example, relationships between color filter patterns and pixel areas; thus the same reference numerals will be used to refer to the same or like parts as those described in the examples of  FIG. 1  to  FIG. 3B , and repetitive explanation concerning the above elements may be omitted. 
         [0096]    Referring to  FIG. 4  to  FIG. 6B , a first display substrate  400  of a display panel  2000  includes a first base substrate  110 , a first blocking pattern  120 , and a color filter pattern  410 . 
         [0097]    The color filter pattern  410  partially overlaps the pixel area PA. In particular, the color filter pattern  410  overlaps a portion of the pixel area PA without completely covering the pixel area PA. For example, the pixel area PA may be divided into a first portion P 1 , a second portion P 2  and a third portion P 3  in order. The color filter pattern  410  overlaps the second portion P 2  without overlapping the first portion P 1  or the third portion P 3 . 
         [0098]    When the color filter patterns  410  are formed, the color filter patterns  410  may be aligned or misaligned with (e.g., disposed symmetrically or asymmetrically with respect to) the pixel areas PAs. According to one or more embodiments, although the color filter pattern  410  may move with respect to the corresponding pixel area PA in the first direction D 1 , the size of an overlapping area OA (defined by upper and lower edges of the color pattern  410  and left and right sides of the pixel area PA) in which the color filter pattern  410  and the corresponding pixel area PA overlap each other may remain constant. 
         [0099]    For example, when the color filter patterns  410  is aligned with (e.g., disposed symmetrically with respect to) the pixel area PA along the first direction D 1 , the color filter pattern  410  may overlap with the pixel area PA at the second portion P 2  between a first reference line RL 1  and a second reference line RL 2 . Thus, the second portion P 2  displays color light as the overlapping area OA to increase the color reproducibility, and the first portion P 1  and the third portion P 3  display white light as two non-overlapping areas NOAs to increase the transmission rate. The overlapping area OA (or the second portion P 2 ) is defined by the upper and lower edges of the color filter pattern  410  and the left and right sides of the pixel area PA. Since the color filter  410  is disposed symmetrically with respect to the pixel PA, the two non-overlapping areas NOAs (or portions P 1  and P 3 ) may have the same size. 
         [0100]    On the other hand, when the color filter patterns  410  is misaligned with (e.g., disposed asymmetrically with respect to) the pixel area PA along the first direction D 1 , the color filter pattern  410  may overlap the pixel area PA at another second portion P 2 ′ between a third reference line RL 3  moved from the first reference line RL 1  in the first direction D 1  and a fourth reference line RL 4  moved from the second reference line RL 2  in the first direction D 1 . Thus, the second portion P 2 ′ displays the color light as the overlapping area OA′ to increase the color reproducibility, and the first portion P 1 ′ and the third potion P 3 ′ display the white light as two non-overlapping area NOA&#39;s to increase the transmission rate. The overlapping area OA′ (or the second portion P 2 ′) is defined by the upper and lower edges of the color filter pattern  410  and the left and right sides of the pixel area PA. Since the color filter  410  is disposed asymmetrically with respect to the pixel PA, the two non-overlapping areas NOA&#39;s (or portions P 1 ′ and P 3 ′) may have different sizes. As illustrated in the example of  FIG. 6B , the first portion P 1 ′ is smaller than the third portion P 3 ′. 
         [0101]    Although the color filter pattern  410  moves in the first direction D 1 , the area (or size) of the overlapping area OA according to the first and the second reference lines RL 1  and RL 2  is substantially the same as the area (or size) of the overlapping area OA′ according to the third and the fourth reference lines RL 3  and RL 4 , wherein the upper and lower edges of the color filter pattern  410  remain between the upper and lower sides of the pixel area PA 
         [0102]    As illustrated in the example of  FIG. 5 , the first display substrate  100  may further include an over-coating layer  140 , a common electrode layer  150 , and a column spacer  160 . The column spacer  160  is disposed over the first blocking pattern  120 . The color filter pattern  410  is not formed on the first blocking pattern  120 , so that the column spacer  160  may be directly formed on the first blocking pattern  120 , and so that the color filter pattern is not disposed between the column spacer  160  and the first blocking pattern  120 . Thus, the display panel  2000  may have a substantially constant liquid crystal margin at or near the column spacer  160 . 
         [0103]    According to the examples of  FIGS. 4-6B , although the color filter patterns  410  may be aligned or misaligned with (e.g., disposed asymmetrically with respect to) the pixel area PA along the first direction D 1 , the color reproducibility and the transmission rate of the display panel  2000  including the first display substrate  400  may remain substantially constant and/or substantially consistent for different pixel areas. 
         [0104]      FIG. 7  is a plan view illustrating a first display substrate according to an example embodiment of the present invention. 
         [0105]    A first display substrate according to the present example embodiment is substantially the same as the first display substrate according to the examples of  FIG. 4  to  FIG. 6B  except, for example, the shapes of the color filter patterns; thus the same reference numerals will be used to refer to the same or like parts as those described in the examples of  FIG. 4  to  FIG. 6B , and repetitive explanation concerning the above elements may be omitted. 
         [0106]    Referring to  FIG. 7 , a first display substrate  500  includes a first base substrate  110 , a first blocking pattern  120 , and a color filter pattern  510 . 
         [0107]    A pixel area PA defined by the first blocking pattern  120  may have a rectangular shape. The pixel area PA may have the rectangular shape extending in first direction D 1  and a second direction crossing the first direction D 1 . The pixel area PA may have a first length L 1  extending in the first direction D 1  and a first width W 1  extending in the second direction D 2 . The first length L 1  may be about three times the first width W 1 . The pixel areas PA may be spaced apart from each other by the blocking area BA, and arranged in a matrix shape. 
         [0108]    The color filter pattern  510  may have a stripe shape extending in the first direction D 1  and the second direction D 2 . The color filter pattern  510  may have a third length L 3  extending in the first direction D 1 . The third length L 3  is smaller than the first length L 1 . As the third length L 3  increases, the color reproducibility may increase, and as the third length L 3  decreases, the transmission rate may increase. 
         [0109]    The color filter pattern  510  partially overlaps each of the pixel areas PAs adjacent to each other along the second direction D 2 . In other words, the color filter pattern overlaps a portion of each pixel area PA of a plurality of pixel areas PAs without completely covering the pixel area PA, wherein the plurality of pixel areas PAs is disposed along the second direction D 2 . 
         [0110]    For example, the pixel area PA may be divided into a first portion P 1 , a second portion P 2  and a third portion P 3  disposed in order in the first direction D 1 . The color filter pattern  510  overlaps the second portion P 2  of each of the plurality of the pixel areas PAs indisposed along the second direction D 2 . The second portions P 2   s  are defined by the upper and lower edges of the color filter pattern  510  and the left and right sides of the pixel areas PAs. 
         [0111]    When the color filter patterns  510  are formed, the color filter patterns  510  may be aligned or misaligned with (e.g., disposed symmetrically or asymmetrically with respect to) the pixel areas PAs. According to the example embodiment of  FIG. 7 , although the color filter pattern  510  may be misaligned (or disposed asymmetrically) with respect to the corresponding pixel areas PAs along the first direction D 1 , the total size of overlapping areas OAs in which the color filter pattern  510  and the corresponding pixel areas PAs overlap may remain substantially constant and/or substantially consistent for different pixel areas, wherein the upper and lower edges of the color filter pattern  510  remain between the upper and lower sides of the pixel areas PAs. 
         [0112]    The overlapping areas OA according to the present example embodiment are substantially the same as those according to the example embodiment of  FIG. 4 , so that any repetitive explanation concerning the above elements will be omitted. 
         [0113]    According to the present example embodiment of  FIG. 7 , although the color filter patterns  510  may be misaligned with (e.g., disposed symmetrically or asymmetrically with respect to) the pixel areas PAs along the first direction D 1 , the color reproducibility and the transmission rate of the first display substrate  500  may remain substantially constant and/or substantially consistent for different pixel areas. 
         [0114]      FIG. 8  is a plan view illustrating a first display substrate according to an example embodiment of the present invention.  FIG. 9  is a cross-sectional view illustrating a display panel including the first display substrate taken along a line III-III′ of  FIG. 8 . 
         [0115]    A first display substrate according to the present example embodiment is substantially the same as the first display substrate according to the examples of  FIG. 1  to  FIG. 6B  except, for example, a color pattern including a color filter pattern; thus the same reference numerals will be used to refer to the same or like parts as those described in the examples of  FIG. 1  to  FIG. 6B , and repetitive explanation concerning the above elements may be omitted. 
         [0116]    Referring to  FIG. 8  and  FIG. 9 , a first display substrate  600  of a display panel  3000  includes a first base substrate  110 , a first blocking pattern  120 , and a color pattern  610 . 
         [0117]    The color pattern  610  extends in the first direction D 1 . The color pattern  610  may have a second width W 2  extending in the second direction D 2 . The second width W 2  is larger than the first width W 1  associated with the pixel area PA, so that the color pattern  610  may have a left overlay margin and a right overlay margin disposed along the second direction D 2 . The color pattern  610  includes a color filter pattern  611  and a color connecting pattern  612 . 
         [0118]    The color filter pattern  611  may have a rectangular shape. The color filter pattern  611  may have the rectangular shape extending in the first direction D 1  and the second direction D 2 . Analogous to the color filter pattern  410  illustrated in the example of  FIG. 4 , the color filter pattern  611  also may have a second length L 2  extending in the first direction D 1  and the second width W 2 . 
         [0119]    The color connecting pattern  612  is disposed between color filter patterns  611  adjacent to each other along the first direction D 1 , and connects the color filter patterns  611  adjacent to each other. The color connecting pattern  612  extends in the first direction D 1 , and corresponds to a boundary between the blocking area BA of the first blocking pattern  120  and the pixel area PA. 
         [0120]    The color filter patterns  611  adjacent to each other and the color connecting patterns  612  disposed between the color filter patterns  611  adjacent to each other may define an opening  613 . The opening  613  may have a third width W 3  smaller than the first width W 1 . Thus, the opening  613  may be disposed between the overlay margins of the color pattern  610  overlapping the pixel area PA and disposed along the second direction D 2 . Alternatively, the opening  613  may have a fourth width larger than the first width W 1 . 
         [0121]    The color pattern  610  partially overlaps each of the pixel areas PAs adjacent to each other along the first direction D 1  without overlapping the pixel areas PAs at the openings  613 . 
         [0122]    For example, the pixel area PA may be divided into a first portion P 1 , a second portion P 2 , and a third portion P 3  disposed in order along the first direction D 1 . The color filter pattern  611  overlaps with the second portion P 2  defined by the upper and lower edges of the color filter pattern  611  and the left and right sides of the pixel area PA. The color connecting pattern  612  partially overlaps each of the third portion P 3  of the pixel area PA (defined by the lower edge of a color filter pattern  611  and the lower, left, and right sides of the pixel area PA) and the first portion P 1  of a second pixel area PA (defined by the upper edge of another color filter pattern  611  and the upper, left, and right sides of the second pixel area PA) adjacent to the pixel area PA along the first direction D 1 . The opening  613  overlaps the third portion P 3  of the pixel area PA and the first portion P 1  of the second pixel area PA adjacent to the pixel area PA along the first direction D 1 . 
         [0123]    When the color pattern  610  is formed, the color pattern  610  may be aligned or misaligned with (e.g., disposed symmetrically or asymmetrically with respect to) the pixel areas PAs along the first direction D 1 . According to the example embodiment of  FIG. 8 , although the color pattern  610  may be misaligned (or disposed asymmetrically) with respect to the pixel areas PAs along the first direction D 1 , the size of an overlapping area OA in which the color pattern  610  and one pixel area PA overlap each other may remain constant. 
         [0124]    The overlapping areas OAs according to the present example embodiment are substantially the same as those according to the previous example embodiment of  FIG. 4 , so that repetitive explanation concerning the above elements may be omitted. 
         [0125]    According to the present example embodiment of  FIG. 8 , although the color filter patterns  611  may be misaligned (or disposed asymmetrically) with respect to the pixel areas PAs along the first direction D 1 , the color reproducibility and the transmission rate of the display panel of the first display substrate  600  may remain substantially constant and/or substantially consistent for different pixel areas. 
         [0126]      FIG. 10  is a plan view illustrating a first display substrate according to an example embodiment of the present invention. 
         [0127]    A first display substrate according to the present example embodiment is substantially the same as the first display substrate according to the examples of  FIG. 1  to  FIG. 3B  except, for example, a shape of a color filter pattern; thus the same reference numerals will be used to refer to the same or like parts as those described in the examples of  FIG. 1  to  FIG. 3B , and repetitive explanation concerning the above elements may be omitted. 
         [0128]    Referring to  FIG. 10 , a first display substrate  700  includes a first base substrate  110 , a first blocking pattern  120  and a color pattern  710 . 
         [0129]    The color pattern  710  extends in a first direction D 1 . The color pattern  710  may have a second width W 2  extending in a second direction D 2  crossing the first direction D 1 . The second width W 2  is larger than a first width W 1  of a pixel area PA. Thus, the color pattern  710  may have a left overlay margin and a right overlay margin overlapping the pixel area PA and disposed along the second direction D 2 . The color pattern  710  includes a color filter pattern  711  and a color connecting pattern  712 . 
         [0130]    The color filter pattern  711  has a rectangular shape. The color filter pattern  711  may have the rectangular shape extending in the first direction D 1  and extending in the second direction D 2 . The color filter pattern  711  may have a second length L 2  extending in the first direction D 1  and the second width W 2 . 
         [0131]    The color connecting pattern  712  is disposed between the color filter patterns  711  adjacent to each other along the first direction D 1 , and connects the color filter patterns  711  adjacent to each other. The color connecting pattern  712  extends in the first direction D 1 , and corresponds to a boundary between a blocking area BA of the first blocking pattern  120  and the pixel area PA. 
         [0132]    The color filter patterns  711  adjacent to each other and the color connecting patterns  712  disposed between the color filter patterns  711  adjacent to each other may define an opening  713 . The opening  713  may have a third width W 3  smaller than the first width W 1 . Thus, the opening  713  may be disposed between the left and right overlay margins of the color pattern  710  overlapping the pixel area PA and disposed along the second direction D 2 . Alternatively, the opening  713  may have a fourth width larger than the first width W 1 . 
         [0133]    The color pattern  710  partially overlaps with each pixel area PA of the pixel areas PAs adjacent to each other along the first direction D 1  without completely covering the pixel area PA. One color filter pattern  711  partially overlaps with each of two pixel areas PA adjacent to each other along the first direction D 1 . 
         [0134]    For example, the pixel area PA may be divided into a first portion P 1  (defined by the lower edge of a first color filter pattern  711  and the upper, left, and right sides of the pixel area PA), a second portion P 2  (defined by the lower edge of the first color filter pattern  711 , the upper edge of a second color filter pattern  711 , and the left and right sides of the pixel area PA), and a third portion P 3  (defined by the upper edge of the second color filter pattern  711  and the lower, left, and right sides of the pixel area PA) disposed in order along the first direction D 1 . The color filter pattern  711  overlaps the third portion P 3  of one pixel area PA and the first portion P 1  of another pixel area PA adjacent to the pixel area PA along the first direction D 1 . The color connecting pattern  712  partially overlaps each of the second portion P 2  of the pixel area PA and the second portion P 2  of another pixel area PA adjacent to the pixel area PA along the first direction D 1 . The opening  713  overlaps with each of the second portion P 2  of the pixel area PA and the second portion P 2  of another pixel area PA adjacent to the pixel area PA along the first direction D 1 . The color pattern  710  overlaps the pixel areas PAs at overlapping areas where the color filter patterns  711  and the color connecting patterns  712  overlap the pixel areas. Each of the overlapping areas surrounds a non-overlapping area that corresponds to an opening  713  of the color pattern  710 . 
         [0135]    When the color pattern  710  is formed, the color pattern  710  may be aligned or misaligned with (e.g., disposed symmetrically or asymmetrically with respect to) the pixel areas PAs along the first direction D 1 . According to the t example embodiment of  FIG. 10 , although the color pattern  710  may be misaligned (or disposed asymmetrically) with respect to the pixel areas PA along the first direction D 1 , the size of an overlapping area OA in which the color pattern  710  and one pixel area PA overlap each other may remain substantially constant and/or substantially consistent for different pixel areas, wherein the upper and lower edges of the opening  713  remain between the upper and lower sides of the pixel area PA. 
         [0136]    The overlapping areas OA according to the present example embodiment are substantially the same as those according to the example embodiment of  FIG. 1  except, for example, the additional overlapping areas contributed by the color connecting pattern  712 ; repetitive explanation concerning the above elements may be omitted. 
         [0137]    According to the example embodiment of  FIG. 10 , although the color filter patterns  710  may be misaligned (or disposed asymmetrically) with respect to the pixel areas PA along the first direction D 1 , the color reproducibility and the transmission rate of the display panel of the first display substrate  700  may remain substantially constant and/or substantially consistent for different pixel areas. 
         [0138]      FIG. 11  is a cross-sectional view illustrating a second display substrate according to an example embodiment of the present invention. 
         [0139]    A second display substrate according to the present example embodiment is substantially the same as the second display substrate according to the example embodiment of  FIG. 2  except, for example, color filter patterns and a protecting layer; thus the same reference numerals will be used to refer to the same or like parts as those described in the example embodiment of  FIG. 2 , and repetitive explanation concerning the above elements may be omitted. 
         [0140]    Referring to  FIG. 11 , a display panel  5000  includes a first display substrate  910 , a second display substrate  920  facing the first substrate  910 , and a liquid crystal layer  300  disposed between the first display substrate  910  and the second display substrate  920 . 
         [0141]    The first display substrate  910  includes a first base substrate  110  and a first blocking pattern  120 . The first display substrate  910  may further include an over-coating layer  140 , a common electrode layer  150 , and a column spacer  150 . 
         [0142]    The second display substrate  920  includes a second base substrate  210 , a switching element  220 , a color filter pattern  921 , and a pixel electrode PE. The switching element  220  and the pixel electrode PE are formed in the pixel area PA. The switching element  220  includes a gate electrode, a source electrode and a drain electrode. 
         [0143]    A color filter pattern  921  according to the present example embodiment is substantially the same as the color filter pattern according to the example embodiment of  FIG. 2  excepting that the color filter pattern  921  is not formed on the first display substrate  910 , but formed on the second display substrate  920  and contacting the second base substrate  210 ; repetitive explanation concerning the above elements may be omitted. 
         [0144]    A color filter pattern  921  partially overlaps the pixel areas PA 1  and PA 2  disposed adjacent to each other, and is disposed on the switching element  220  to contact and cover the switching element  220 . For example, one color filter pattern  921  overlaps with an area adjacent to a first end of the pixel area PA 1 , and another color filter pattern  921  spaced apart from the color filter pattern  921  overlaps an area adjacent to a second end of the pixel area PA 1 . The color filter pattern  921  is not disposed in an area between the first end and the second end of the pixel area PA 1 , so that the second display substrate  920  may have a stepped portion. The color filter pattern  921  may include a contact hole partially exposing the switching element  220 . 
         [0145]    Alternatively, the color filter pattern  921  may have a shape of one of the color filter patterns and a corresponding relation of the color filter pattern and the pixel area according to the examples of  FIGS. 4 ,  7 ,  8  and  10 . 
         [0146]    The pixel electrode PE is disposed in the pixel area (e.g., pixel area PA 1 ) and extends from one color filter pattern  921  to another color filter pattern  921  spaced apart from the color filter pattern  921 ; the pixel electrode contacts two adjacent color filter patterns  921 . The pixel electrode PE is electrically connected to the switching element  220  via the contact hole. 
         [0147]    According to the present example embodiment of  FIG. 11 , although the color filter patterns  921  may be misaligned (or disposed asymmetrically) with respect to a pixel area along the first direction D 1 , the color reproducibility and the transmission rate of the display panel including the second display substrate  920  may remain substantially constant and/or substantially consistent for different pixel areas. 
         [0148]      FIG. 12  is a cross-sectional view illustrating a second display substrate according to an example embodiment of the present invention. 
         [0149]    A second display substrate according to the present example embodiment is substantially the same as the second display substrate according to the example embodiment of  FIG. 11  except, for example, a protecting layer; thus the same reference numerals will be used to refer to the same or like parts as those described in the example embodiment of  FIG. 11 , and repetitive explanation concerning the above elements may be omitted. 
         [0150]    Referring to  FIG. 12 , a display panel  6000  includes a first display substrate  910 , a second display substrate  930  facing the first display substrate  910 , and a liquid crystal layer  300  disposed between the first display substrate  910  and the second display substrate  930 . 
         [0151]    The first display substrate  910  includes a first base substrate  110  and a first blocking pattern  120 . The first display substrate  910  may further include an over-coating layer  140 , a common electrode layer  150 , and a column spacer  160 . 
         [0152]    The second display substrate  930  includes a second base substrate  210 , a switching element  220 , a color filter pattern  921 , a protecting layer  230 , and a pixel electrode PE. 
         [0153]    The color filter pattern  921  partially overlaps the pixel areas PA 1  and PA 2  disposed adjacent to each other, and is disposed on the switching element  220  to cover the switching element  220 . The color filter pattern  921  may include a contact hole partially exposing the switching element  220 . 
         [0154]    The protecting layer  230  is formed on the second base substrate  210 , covers the color filter pattern  921 , and planarizes the second display substrate  930 . The protecting layer  230  may include a contact hole partially exposing the switching element  220 . 
         [0155]    The pixel electrode PE is disposed in a pixel area (e.g., PA 1 ) and is disposed on the protecting layer  230 ; the pixel electrode PE extends from one color filter pattern  921  to another color filter pattern  921  spaced apart from the color filter pattern  921 . The pixel electrode PE is electrically connected to the switching element  220  via the contact holes. 
         [0156]    According to the present example embodiment of  FIG. 12 , although the color filter pattern  921  may be misaligned (or disposed asymmetrically) with respect to a pixel area along the first direction D 1 , the color reproducibility and the transmission rate of the display panel may remain substantially constant and/or substantially consistent for different pixel areas. 
         [0157]      FIG. 13  is a cross-sectional view illustrating a second display substrate according to an example embodiment of the present invention. 
         [0158]    A second display substrate according to the present example embodiment is substantially the same as the second display substrate according to the previous example embodiment of  FIG. 11  except, for example, a blocking pattern and a color filter pattern, thus the same reference numerals will be used to refer to the same or like parts as those described in the previous example embodiment of  FIG. 11 , and repetitive explanation concerning the above elements may be omitted. 
         [0159]    Referring to  FIG. 13 , a display panel  7000  includes a first display substrate  940 , a second display substrate  950  facing the first display substrate  940 , and a liquid crystal layer  300  disposed between the first display substrate  940  and the second display substrate  950 . 
         [0160]    The first display substrate  940  may include a first base substrate  110 , a common electrode layer  150 , and a column spacer  160 . 
         [0161]    The second display substrate  950  includes a second base substrate  210 , a switching element  220 , a first blocking pattern  922 , a color filter pattern  921 , and a pixel electrode PE. The first blocking pattern  922  may be formed on the switching element  220  to partially overlap with the switching element  220 . Alternatively, the first blocking pattern  922  may be formed under the switching element  220  to partially overlap with the switching element  220 . 
         [0162]    The color filter pattern  921  is formed on the second base substrate  210  including the first blocking pattern  922  to cover the switching element  220  and the first blocking pattern  922 . 
         [0163]    The color filter pattern  921  partially overlaps the pixel areas PA 1  and PA 2  disposed adjacent to each other, and is disposed on and contacts the switching element  220  and the first blocking pattern  922  to cover the switching element  220  and the first blocking pattern  922 . For example, one color filter pattern  921  overlaps with an area adjacent to a first end of the pixel area PA 1 , and another color filter pattern  921  overlaps with an area adjacent to a second end of the pixel area PA 1 . The color filter  921  is not disposed between the first end and the second end of the pixel area PA, and thus the second display substrate  950  may have a stepped portion. 
         [0164]    According to the present example embodiment of  FIG. 13 , although the color filter pattern  921  may be misaligned (or disposed asymmetrically) with respect to a pixel area along the first direction D 1 , the color reproducibility and the transmission rate of the display panel including the second display substrate  950  may remain substantially constant and/or substantially consistent for different pixel areas. 
         [0165]      FIG. 14  is a cross-sectional view illustrating a second display substrate according to an example embodiment of the present invention. 
         [0166]    A second display substrate according to the present example embodiment is substantially the same as the second display substrate according to the previous example embodiment of  FIG. 13  except, for example, a protecting layer; thus the same reference numerals will be used to refer to the same or like parts as those described in the previous example embodiment of  FIG. 13 , and repetitive explanation concerning the above elements may be omitted. 
         [0167]    Referring to  FIG. 14 , a display panel  8000  includes a first display substrate  940 , a second display substrate  960  facing the first display substrate  940 , and a liquid crystal layer  300  disposed between the first display substrate  940  and the second display substrate  960 . 
         [0168]    The first display substrate  940  may includes a first base substrate  110 , a common electrode layer  150 , and a column spacer  160 . 
         [0169]    The second display substrate  960  includes a second base substrate  210 , a switching element  220 , a first blocking pattern  922 , a color filter pattern  921 , a protecting layer  230 , and a pixel electrode PE. The first blocking pattern  922  is formed on the second base substrate  210  and partially overlaps with the switching element  220 . 
         [0170]    The color filter pattern  921  is formed on the second base substrate  210  and covers the switching element  220  and the first blocking pattern  922 . The color filter pattern  921  may include a contact hole partially exposing the switching element  220 . 
         [0171]    The protecting layer  230  is formed on the second base substrate, covers the color filter pattern  921 , and planarizes the second display substrate  960 . A portion of the protecting layer  230  is disposed between adjacent color filter patterns  921 . The protecting layer  230  may include a contact hole partially exposing the switching element  220 . 
         [0172]    The pixel electrode PE is disposed in a pixel area (e.g., PA 1 ) and is disposed on the protecting layer  230 ; the pixel electrode PE extends from one color filter pattern  921  to another color filter pattern  921  spaced apart from the color filter pattern  921 . The pixel electrode PE is electrically connected to the switching element  220  via the contact holes. 
         [0173]    According to the example embodiment of  FIG. 14 , although the color filter pattern  921  may be misaligned (or disposed asymmetrically) with respect a pixel area along the first direction D 1 , the color reproducibility and the transmission rate of the display panel including a second display substrate  960  may remain substantially constant and/or substantially consistent for different pixel areas. 
         [0174]      FIG. 15  is a plan view illustrating a first display substrate according to an example embodiment of the present invention.  FIG. 16  is a cross-sectional view illustrating a display panel including the first display substrate taken along a line IV-IV′ of  FIG. 15 . 
         [0175]    A first display substrate according to the present example embodiment is substantially the same as the first display substrate including the first display substrate according to the examples of  FIGS. 1-2  except, for example, a second blocking pattern; thus the same reference numerals will be used to refer to the same or like parts as those described in the previous example embodiment of  FIG. 1 , and repetitive explanation concerning the above elements may be omitted. 
         [0176]    Referring to  FIG. 15  and  FIG. 16 , a first display substrate  100 A of a display panel  4000  includes a first base substrate  110 , a first blocking pattern  120 , a second blocking pattern  170 , and a color filter pattern  130 . 
         [0177]    The first blocking pattern  120  defines a plurality of pixel areas PA on the first base substrate  110 . The pixel area PA may have a rectangular shape. The pixel area PA may have the rectangular shape extending in a first direction D 1  and extending a second direction D 2  crossing the first direction D 1 . The pixel areas PA may be spaced apart from each other by the blocking area BA, and arranged in a matrix. 
         [0178]    The second blocking pattern  170  is disposed in a first pixel area PA 1  that has a defect. For example, when at least one of a first color filter pattern  131  and a second color filter pattern  132  partially overlapping the first pixel area PA 1  is partially lost/damaged or an impurity flows in at least one of the first and second color filter patterns  131  and  132 , portions of the reduced first and second color filter patterns  131 ′ and  132 ′ overlapping the first pixel area PA 1  is replaced by the second blocking pattern  170 , in order to improve visibility, so that the first pixel area PA 1  may be repaired. If a pixel area PA is fully repaired, because there is no backlight assembly, the repaired pixel area (or a defect) is more visible. According to the present example embodiment, a pixel area PA is partially repaired, although there is no backlight assembly, the repaired pixel area is less visible. Thus, the visibility may be improved. 
         [0179]    The first and second color filter patterns  131  and  132  are adjacent to each other in the first direction D 1 . 
         [0180]      FIGS. 17A and 17B  are cross-sectional views illustrating a method of repairing a first pixel area of the first display substrate of  FIG. 15 . 
         [0181]    Referring to  FIG. 17A  and  FIG. 17B , a first laser LS 1  is irradiated to the first and second color filter patterns  131  and  132  overlapping with the first pixel area PA 1  having the defect, so that the first and second color filter patterns  131  and  132  overlapping with the first pixel area PA 1  is burned off. Thus, a gap G is formed between the first base substrate  110  and remaining first and second filter patterns  131 ′ and  132 ′. Then, a second laser LS 2  is irradiated to the first blocking pattern  120  adjacent to the remaining first and second filter patterns  131 ′ and  132 ′, so that the first blocking pattern  120  flows in the gap G. Thus, the second blocking pattern  170  connected to the first blocking pattern  120  is formed between the first base substrate  110  and the remaining first and second filter patterns  131 ′ and  132 ′ at overlapping areas corresponding to portions P 1  and P 3 . The thickness of the first blocking pattern  120  may be reduced, while the area blocked by the first blocking pattern  120  may remain substantially unchanged. 
         [0182]    In one or more embodiments, all of the portions of the first and second color filter patterns  131  and  132  overlapping with the first pixel area PA 1  (corresponding to portions P 1  and P 3 ) may be totally burned off. 
         [0183]    When the first pixel area PA 1  is divided into a first portion P 1 , a second portion P 2 , and a third portion P 3  in order along the first direction D 1 , the second blocking pattern  170  is disposed in the first and third portions P 1  and P 3  overlapping the remaining first and second color filter patterns  131 ′ and  132 ′. 
         [0184]    The second blocking pattern  170  has a length smaller than that of the first pixel area PA 1  and a width larger than that of the first pixel area PA 1 . 
         [0185]    A second pixel area PA 2  substantially having no defect is substantially the same as the pixel area according to the example of  FIG. 1 , and thus repetitive explanation concerning the second pixel area PA 2  will be omitted. 
         [0186]    According to the present example embodiment of  FIG. 15 , the color filter patterns  131  and  132  do not correspond to the whole of the first pixel area PA 1 , but correspond to the first and third portions P 1  and P 3  of the first pixel area PA 1 . Thus, the portion P 2  of the first pixel area PA 1  is not repaired, but the first and third portions P 1  and P 3  of the first pixel area PA 1  may be repaired. 
         [0187]      FIG. 18  is a plan view illustrating a first display substrate according to an example embodiment of the present invention.  FIG. 19  is a cross-sectional view illustrating a display panel including the first display substrate taken along a line V-V′ of  FIG. 18 . 
         [0188]    A first display substrate according to the present example embodiment is substantially the same as the first display substrate including the first display substrate according to the previous example embodiment of  FIG. 4  except, for example, a second blocking pattern; thus the same reference numerals will be used to refer to the same or like parts as those described in the previous example embodiment of  FIG. 4 , and repetitive explanation concerning the above elements may be omitted. 
         [0189]    Referring to  FIG. 4 ,  FIG. 18 , and  FIG. 19 , a first display substrate  400 A of a display panel  5000  includes a first base substrate  110 , a first blocking pattern  120 , a second blocking pattern  180 , and a color filter pattern  410 ′. 
         [0190]    The second blocking pattern  180  is disposed in a first pixel area PA 1  that has a defect. For example, when the color filter pattern  410  overlapping with the first pixel area PA 1  is partially lost/damaged or an impurity flows in the color filter pattern  410 , a portion of the reduced color filter pattern  410 ′ overlapping with the first pixel area PA 1  is replaced by the second blocking pattern  180  to order to improve visibility, so that the first pixel area PA 1  may be repaired. If a pixel area PA is fully repaired, because there is no backlight assembly, the repaired pixel area (or a defect) is more visible. According to the present example embodiment, a pixel area PA is partially repaired, although there is no backlight assembly, the repaired pixel area is less visible. Thus, the visibility may be improved. 
         [0191]    Hereinafter, a method of repairing the first pixel area PA 1  having the defect will be explained. 
         [0192]    A first laser LS 1  is irradiated to the color filter pattern  410  overlapping with the first pixel area PA 1 , so that the color filter pattern  410  overlapping with the first pixel area PA 1  is burned off. Thus, a gap is formed between the first base substrate  110  and remaining color filter pattern  410 ′. Then, a second laser LS 2  is irradiated to the first blocking pattern  120  adjacent to the remaining color filter pattern  410 ′, so that the first blocking pattern  120  flows in the gap. Thus, the second blocking pattern  170  connected to the first blocking pattern  120  is formed between the first base substrate  110  and the remaining color filter pattern  410 ′. 
         [0193]    In one or more embodiments, all of the portion of the color filter pattern  410  overlapping with the first pixel area PA 1  (and corresponding to the portion P 2 ) may be totally burned off. 
         [0194]    When the first pixel area PA 1  is divided into a first portion P 1 , a second portion P 2  and a third portion P 3  in order along the first direction D 1 , the second blocking pattern  420  is disposed in the second portion P 2  overlapping the remaining color filter pattern  410 ′. 
         [0195]    The second blocking pattern  420  has a length smaller than that of the first pixel area PA 1  and a width larger than that of the first pixel area PA 1 . 
         [0196]    A second pixel area PA 2  substantially having no defect is substantially the same as the pixel area according to the example of  FIG. 4 , and thus repetitive explanation concerning the second pixel area PA 2  will be omitted. 
         [0197]    According to the present example embodiment of  FIG. 18 , the color filter pattern  410  does not correspond to the whole of the first pixel area PA 1 , but corresponds to the second portion P 2  of the first pixel area PA 1 . Thus, the portions P 1  and P 3  of the first pixel area PA 1  is not repaired, but the second portion P 2  of the first pixel area PA 1  may be repaired. 
         [0198]      FIG. 20  is a plan view illustrating a first display substrate according to an example embodiment of the present invention.  FIG. 21  is a cross-sectional view illustrating a display panel including the first display substrate taken along a line VI-VI′ of  FIG. 20 . 
         [0199]    A first display substrate according to the present example embodiment is substantially the same as the first display substrate including the first display substrate according to the previous example embodiment of  FIG. 8  except, for example, a second blocking pattern; thus the same reference numerals will be used to refer to the same or like parts as those described in the previous example embodiment of  FIG. 8 , and repetitive explanation concerning the above elements may be omitted. 
         [0200]    Referring to  FIG. 20  and  FIG. 21 , a first display substrate  600 A of a display panel  6000  includes a first base substrate  110 , a first blocking pattern  120 , a second blocking pattern  620 , and a color pattern  610 . 
         [0201]    The second blocking pattern  620  is disposed in a first pixel area PA 1  that has a defect. For example, when the color filter pattern  610  overlapping the first pixel area PA 1  is partially lost/damaged or an impurity flows in the color filter pattern  610 , a portion of the color filter pattern  610  overlapping the first pixel area PA 1  is replaced by the second blocking pattern  620  to order to improve visibility, so that the first pixel area PA 1  may be repaired. If a pixel area PA is fully repaired, because there is no backlight assembly, the repaired pixel area (or a defect) is more visible. According to the present example embodiment, a pixel area PA is partially repaired, although there is no backlight assembly, the repaired pixel area is less visible. Thus, the visibility may be improved. 
         [0202]    Hereinafter, a method of repairing the first pixel area PA 1  having the defect will be explained. 
         [0203]    A first laser LS 1  is irradiated to portions of the color filter pattern  611  and the color connecting pattern  612  of the color pattern  610  overlapping the first pixel area PA 1 , so that the portions of the color filter pattern  611  and the color connecting pattern  612  overlapping with the first pixel area PA 1  are burned off. Thus, gaps are formed between the first base substrate  110  and a remaining color filter pattern  611 ′ and between the first base substrate  110  and a remaining color connecting pattern  612 ′. Then, a second laser LS 2  is irradiated to the first blocking pattern  120  adjacent to the remaining color filter pattern  611 ′ and the remaining color connecting patter  612 ′, so that the first blocking pattern  120  flows in the gaps. Thus, the second blocking pattern  620  connected to the first blocking pattern  120  is formed between the first base substrate  110  and each of the remaining color filter pattern  611 ′ and the remaining color connecting pattern  612 ′. 
         [0204]    When the first pixel area PA 1  is divided into a first portion P 1 , a second portion P 2 , and a third portion P 3  in order along the first direction D 1 , the second blocking pattern  620  is disposed in the second portion P 2  overlapping the remaining color filter pattern  611 ′ and is disposed in portions of the first and third portions P 1  and P 3  overlapping the remaining color connecting pattern  612 ′. The second blocking pattern  620  may have an ‘H’-shape. In one or more embodiments, all of the color filter pattern  611  and the color connecting pattern  612  overlapping with the first pixel area PA 1  may be totally burned off. 
         [0205]    A second pixel area PA 2  substantially having no defect is substantially the same as the pixel area according to the example of  FIG. 8 , and thus repetitive explanation will be omitted. 
         [0206]    According to the example of  FIG. 20 , the color pattern  610  does not correspond to the whole of the first pixel area PA 1 , but correspond to a portion of the first pixel area PA 1 . Thus, the first pixel area PA 1  is not repaired as a whole, but the first pixel area PA 1  may be partially repaired. 
         [0207]      FIG. 22  is a plan view illustrating a first display substrate according to an example embodiment of the present invention. 
         [0208]    A first display substrate according to the present example embodiment is substantially the same as the first display substrate according to the previous example embodiment of  FIG. 10  except, for example, a second blocking pattern; thus the same reference numerals will be used to refer to the same or like parts as those described in the previous example embodiment of  FIG. 10 , and repetitive explanation concerning the above elements may be omitted. 
         [0209]    Referring to  FIG. 22 , a first display substrate  700 A includes a first base substrate  110 , a first blocking pattern  120 , a second blocking pattern  720 , and a color pattern  710 . 
         [0210]    The second blocking pattern  720  is disposed in a first pixel area PA 1  having a defect. For example, when the color filter pattern  710  overlapping the first pixel area PA 1  is partially lost/damaged or an impurity flows in the color filter pattern  710 , a portion of the color filter pattern  710  overlapping the first pixel area PA 1  is replaced by the second blocking pattern  720  to order to improve visibility, so that the first pixel area PA 1  may be repaired. 
         [0211]    Hereinafter, a method of repairing the first pixel area PA 1  having the defect will be explained. 
         [0212]    A first laser LS 1  is irradiated to portions of a first color filter pattern  711  and a first color connecting pattern  712  of the color pattern  710  overlapping the first pixel area PA 1 , so that the portions of the first color filter pattern  711  and the first color connecting pattern  712  of the color pattern  710  overlapping with the first pixel area PA 1  are burned off. Thus, gaps is formed between the first base substrate  110  and a remaining first color filter pattern  711 ′ and between the first base substrate  110  and a remaining first color connecting pattern  712 ′. Then, a second laser LS 2  is irradiated to the first blocking pattern  120  adjacent to the remaining first color filter pattern  711 ′ and the remaining first color connecting pattern  712 ′, so that the first blocking pattern  120  flows into the gaps. Thus, the second blocking pattern  720  is formed between the first base substrate and each of the remaining first color filter pattern  711 ′ and the remaining first color connecting pattern  712 ′. In one or more embodiments, all of the first color filter pattern  711  and the first color connecting pattern  712  overlapping with the first pixel area PA 1  may be totally burned off. 
         [0213]    When the first pixel area PA 1  is divided into a first portion P 1 , a second portion P 2  and a third portion P 3  in order in the first direction D 1 , the second blocking pattern  720  is in the second portion P 2  of the first pixel area PA 1  and portions of the first and third portions P 1  and P 3 . The second blocking pattern  720  may have a hollowed rectangular shape when viewed in a plane. 
         [0214]    A second pixel area PA 2  having no defect is substantially the same as the pixel area according to the previous example embodiment of  FIG. 10 , and thus any repetitive explanation will be omitted. 
         [0215]    According to the example of  FIG. 22 , the color pattern  710  does not correspond to the whole of the first pixel area PA 1 , but correspond to a portion of the first pixel area PA 1 . Thus, the first pixel area PA 1  is not repaired as a whole, but the first pixel area PA 1  may be partially repaired. 
         [0216]      FIG. 23  is a plan view illustrating a first display substrate according to an example embodiment of the present invention.  FIG. 24  is a cross-sectional view illustrating a display panel including the first display substrate taken along a line VII-VII′ of  FIG. 23 . 
         [0217]    A first display substrate according to the present example embodiment is substantially the same as the first display substrate according to the examples of  FIGS. 17A-17B  except, for example, a relation of a second blocking pattern and a color filter pattern and a pixel area; thus the same reference numerals will be used to refer to the same or like parts as those described in the examples of  FIGS. 17A-17B , and repetitive explanation concerning the above elements may be omitted. 
         [0218]    Referring to  FIG. 23  and  FIG. 24 , a first display substrate  800  of a display panel  7000  includes a first base substrate  110 , a first blocking pattern  120 , a second blocking pattern  820 , and a color filter pattern  810 . 
         [0219]    The second blocking pattern  820  is disposed in a first pixel area PA 1  having a defect. For example, when the color filter pattern  810  overlapping the first pixel area PA 1  is partially lost/damaged or an impurity flows in the color filter pattern  810 , a portion of the color filter pattern  810  overlapping the first pixel area PA 1  is replaced by the second blocking pattern  820  to order to improve visibility, so that the first pixel area PA 1  may be repaired. 
         [0220]    Hereinafter, a method of repairing the first pixel area PA 1  having the defect will be explained. 
         [0221]    A first laser LS 1  is irradiated to a portion of the first color filter pattern  810  overlapping the first pixel area PA 1 , so that the portion of the first color filter pattern  810  overlapping with the first pixel area PA 1  is burned off. Thus, a gap is formed between the first base substrate  110  and a remaining first color filter pattern  810 ′. Then, a second laser LS 2  is irradiated to the first blocking pattern  120  adjacent to the remaining first color filter pattern  810 ′. Thus, the second blocking pattern  820  connected to the first blocking pattern  120  is formed between the first base substrate  110  and a remaining first color filter pattern  810 ′. In one or more embodiments, all of the first color filter pattern  810  overlapping with the first pixel area PA 1  may be totally burned off. 
         [0222]    When the first pixel area PA 1  is divided into a first portion P 1  and a second portion P 2  in order along the first direction D 1 , the second blocking pattern  820  is disposed in the first portion P 1  of the first pixel area PA 1 . Alternatively or additionally, the second blocking pattern  820  may be disposed in the second portion P 2  of the first pixel area PA 1 . The second blocking pattern  820  may be disposed in at least one of the first and second portions P 1  and P 2 . 
         [0223]    A second pixel area PA 2  having no defect is substantially the same as the pixel area according to the previous example embodiment of  FIG. 18 , and thus any repetitive explanation will be omitted. 
         [0224]    According to the present example embodiment of  FIG. 23 , the color pattern  810  does not correspond to the whole of the first pixel area PA 1 , but correspond to a portion of the first pixel area PA 1 . Thus, the first pixel area PA 1  is not repaired as a whole, but the first pixel area PA 1  may be partially repaired. 
         [0225]      FIG. 25  is a cross-sectional view illustrating a second display substrate according to an example embodiment of the present invention. 
         [0226]    A second display substrate according to the present example embodiment is substantially the same as the second display substrate according to the previous example embodiment of  FIG. 13  except, for example, a second blocking pattern; thus the same reference numerals will be used to refer to the same or like parts as those described in the previous example embodiment of  FIG. 13 , and repetitive explanation concerning the above elements may be omitted. 
         [0227]    Referring to  FIG. 25 , a display panel  7000 A includes a first display substrate  940 , a second display substrate  950 A facing the first display substrate  940  and a liquid crystal layer  300  disposed between the first display substrate  940  and the second display substrate  950 A. 
         [0228]    The second display substrate  950 A includes a second base substrate  210 , a switching element  220 , a first blocking pattern  922 , a second blocking pattern  923 , a color filter pattern  921 , and a pixel electrode PE. 
         [0229]    The first blocking pattern  922  defines a plurality of pixel areas PA on the second base substrate  210 . The pixel area PA may have a rectangular shape. The pixel area PA may have the rectangular shape extending in a first direction D 1  and a second direction D 2  crossing the first direction D 1 . The pixel areas PA may be spaced apart from each other by the blocking area BA in which the first blocking pattern  922  is formed, and arranged in a matrix. 
         [0230]    The first blocking pattern  922  may be formed on the switching element  220  to partially overlap the switching element  220 . 
         [0231]    The second blocking pattern  923  is disposed in a first pixel area PA 1  having a defect. For example, when a portion of the color filter pattern  921  overlapping with the first pixel area PA 1  is partially lost/damaged or an impurity flows in the color filter pattern  921 , the portion of the color filter pattern  921  overlapping with the first pixel area PA 1  is replaced by the second blocking pattern  923  to order to improve visibility, so that the first pixel area PA 1  may be repaired. 
         [0232]    A method of repairing the first pixel area PA 1  is substantially the same as the method according to the examples of  FIG. 17A  and  FIG. 17B , and thus any repetitive explanation will be omitted. 
         [0233]    The color filter pattern  921  may be substantially the same as the color filter pattern according to the previous example embodiment of the  FIGS. 4 ,  7 ,  8  and  10 , so that the second blocking pattern  923  may be substantially the same as the second blocking pattern according to the previous example embodiments of  FIG. 18  to  FIG. 24 . 
         [0234]    According to the present example embodiment of  FIG. 25 , the color filter pattern  921  does not correspond to the whole of the first pixel area PA 1 , but correspond to a portion of the first pixel area PA 1 . Thus, the first pixel area PA 1  is not repaired as a whole, but the first pixel area PA 1  may be partially repaired. 
         [0235]      FIG. 26  is a cross-sectional view illustrating a second display substrate according to still another example embodiment of the present invention. 
         [0236]    A second display substrate according to the present example embodiment is substantially the same as the second display substrate according to the previous example embodiment of  FIG. 25  except, for example, a second blocking pattern; thus the same reference numerals will be used to refer to the same or like parts as those described in the example embodiment of  FIG. 25 , and repetitive explanation concerning the above elements may be omitted. 
         [0237]    Referring to  FIG. 26 , a display panel  8000 A includes a first display substrate  940 , a second display substrate  960 A facing the first display substrate  940  and a liquid crystal layer  300  disposed between the first display substrate  940  and the second display substrate  960 A. 
         [0238]    The second display substrate  960 A includes a second base substrate  210 , a switching element  220 , a first blocking pattern  922 , a second blocking pattern  923 , a color filter pattern  921 , a protecting layer  230 , and a pixel electrode PE. 
         [0239]    The protecting layer  230  is formed on the second display substrate  960 A including the switching element  220 , a first blocking pattern  922 , a second blocking pattern  923  and a color filter pattern  921 , so that the second display substrate  960 A may be planarized. 
         [0240]    According to the present example embodiment of  FIG. 26 , the color filter pattern  921  does not correspond to the whole of the first pixel area PA 1 , but correspond to a portion of the first pixel area PA 1 . Thus, the first pixel area PA 1  is not repaired as a whole, but the first pixel area PA 1  may be partially repaired. 
         [0241]    According to the present invention, although a color filter pattern is misaligned with respect to a pixel area, an area in which the color filter pattern overlaps with the pixel area may remain substantially constant and/or substantially consistent for different pixel areas, so that a transmission rate and a color reproducibility of a display panel may remain substantially constant and/or substantially consistent for different pixel areas. 
         [0242]    A color filter pattern entirely covers a first blocking pattern between pixel areas adjacent to each other in a longitudinal direction, so that an upper surface of the first blocking pattern may be planarized. Thus, a column spacer may have a constant liquid crystal margin at any positions over the color filter pattern on the first blocking pattern. 
         [0243]    Alternatively, the color filter pattern does not cover anything of the first blocking pattern between the pixel areas adjacent to each other in the longitudinal direction, so that an upper surface of the first blocking pattern may be planarized. Thus, the column spacer may have a constant liquid crystal margin at any positions over the first blocking pattern. 
         [0244]    The color filter pattern partially overlaps with the pixel area, so that the pixel area may be partially repaired.
