Description of the Invention: The present invention relates to a display device, and more particularly to a liquid crystal display device formed by laminating two substrates. [Prior Art] A liquid crystal panel is formed by laminating two substrates and filling a liquid crystal material between the substrates. A pixel circuit scanning signal line 'and a data signal line' including a thin film transistor (hereinafter referred to as TFT) and a pixel electrode are formed on a substrate. A counter electrode is formed on the other substrate, and a color filter including a black matrix is not disposed. Hereinafter, the former is referred to as a TFT substrate, and the latter is referred to as a counter substrate. In a general liquid crystal panel, adjacent pixel circuits in the direction in which the data signal lines are arranged correspond to different colors and are associated with filter assemblies of different colors. Further, in order to improve color reproducibility, no black matrix is placed between adjacent filter elements. Further, in order to increase the aperture ratio, the TFT substrate and the opposite substrate are bonded so that the data signal lines and the black matrix overlap each other. In the invention of the present application, in the patent document, it is described that the width of the black matrix is set to be less than or equal to the width of the data signal line in order to prevent display unevenness due to abnormal shape or misalignment of the black matrix. Patent Document 2 describes that the width of the black matrix is set to 1 〇 μηι or more. [PRIOR ART DOCUMENT] [Patent Document 1] [Patent Document 1] JP-A-2000-298287 [Patent Document 2] International Publication No. 2/6/9/34 Booklet 159230.doc 201222086 [Summary of the Invention] [Problems to be Solved by the Invention] When the TFT substrate and the counter substrate are bonded together, a maximum number of μηη deviations are generated. When this deviation occurs, light is scattered at the end of the data signal line, and the contrast of the liquid crystal panel is lowered (refer to Fig. 8). As shown in FIG. 8, in the liquid crystal panel formed by bonding the TFT substrate 80 and the counter substrate 90, a portion of the light L scattered at the end of the data signal line 81 is blocked by the black matrix 91, and the remaining portion is not The black matrix 91 is blocked and is emitted toward the front. However, if the deviation (d) shown in Fig. 8 increases when the substrate is bonded, the amount of light emitted toward the front side increases. Therefore, the brightness in the black display is increased, and the contrast of the liquid crystal panel is lowered. Further, in the liquid crystal panel, since the position of the data signal line and the black matrix are deviated from the oblique observation, there is a case where the color is mixed between the adjacent pixels to cause a color unevenness (see Fig. 9). When the color Cb is shown in the liquid crystal panel shown in Fig. 9, τρτ of the pixel circuit corresponding to the color ca is turned off, and the TFT of the pixel circuit corresponding to the color cb is turned on. The observer who sees from the front can see the color Cb, but the observer who observes from the direction of the arrow can see that the color 〇3 is mixed with the color Ca. Thus, when viewed from the oblique direction in the liquid crystal panel, a color spot (hereinafter referred to as a squint stain) is generated, and the reproducibility of the color is lowered. / In order to solve the problem of contrast and squint color, as described in Patent Document 2, it is only necessary to enlarge the width of the black matrix. However, if the black moment width is increased, the aperture ratio is lowered, and the display image is darkened. problem. On the other hand, if the width of the black matrix or the information letter 159230.doc 201222086 is reduced to increase the aperture ratio, contrast and squint stains become a problem. Therefore, the object of the present invention is to provide a liquid crystal display device which is excellent in aperture ratio, contrast, and color reproducibility. [Means for Solving the Problems] A first aspect of the present invention is a liquid crystal display device in which two substrates are bonded together, and includes: a first substrate including a plurality of two-dimensionally arranged a pixel circuit and a plurality of data signal lines arranged in parallel with each other; and a second substrate including a plurality of filter elements corresponding to the pixel circuits and disposed adjacent to an arrangement direction of the data signal lines a black matrix between the filter modules; and the first and second substrates are bonded such that the black matrix covers the data signal line; and the width of the black matrix is 7 μm or less 'the black side of each side The width of the matrix is 1 μm or more wider than the width of the data signal line, and the sum of the width of the black matrix and the width of the data signal line is 9 μm or more. According to a second aspect of the present invention, in the first aspect of the invention, the first and second substrates are bonded such that a central axis of the black matrix overlaps with a central axis of the data signal line. [Effects of the Invention] According to the first aspect of the present invention, the aperture ratio can be increased by setting the width of the black matrix to 7 μη or less. The contrast can be improved by making the width of the black matrix on each side wider than the width of the data signal line by i μπι or more. The color reproducibility can be improved by setting the sum of the width of the black matrix and the width of the data signal line to 9 or higher by 159230.doc 201222086. Therefore, a liquid crystal display device excellent in aperture ratio, contrast, and color reproducibility can be provided. According to the second aspect of the present invention, even when there is a variation in the bonding of the substrates, the decrease in the aperture ratio can be minimized. [Embodiment] FIG. 1 is a block diagram showing the configuration of a liquid crystal panel according to an embodiment of the present invention. The liquid crystal panel 1 shown in Fig. 1 is formed by laminating a TFT substrate 1A and a counter substrate 20 with a liquid crystal material (not shown) interposed between the substrates. Hereinafter, m and η are integers of 2 or more, and 丨 is an integer of 1 or more and m or less, and is an integer of η or less. On the TFT substrate 1A, claw scanning signal lines G1 to Gm, n data signal lines S1 to Sn, and (mxn) pixel circuits Pij are formed. The scanning signal lines (1) to Gm are arranged in parallel with each other, and the data signal lines are arranged in parallel with each other so as to be orthogonal to the scanning signal lines G1 to Gm. The pixel circuit is called to include the TFT 11 and the pixel electrode 12, and corresponds to The intersection of the scanning signal line (1) and the data signal line sj is two-dimensionally arranged. The gate terminal, the source terminal and the 汲 terminal of the TFT u are respectively connected to the scanning signal line Gi, the data signal line and the pixel electrode 12. The scanning signal line is also referred to as a gate bus line or a gate line, and the data signal line is also referred to as a source bus line or a source line. A counter electrode (not shown) is formed on the opposite substrate 20, and A color filter is provided. Fig. 2 is a view showing a configuration of a color filter disposed on the opposite substrate 2. As shown in Fig. 2, the color filter includes a plurality of filters corresponding to the pixel circuit. The two pixel circuits Pij' arranged in the direction of the arrangement of the data signal lines sl~Sn 159230.doc 201222086 (the direction in which the scanning signal lines G1 to Gm extend in the horizontal direction) correspond to the red and green colors, respectively. And blue corresponding filter assembly 2 1r, 21g, and 21b are associated with each other. The black (four) 22 u matrix 22 is disposed between adjacent filter assemblies 21 in the direction in which the scanning signal lines G1 to Gm are arranged (the direction in which the data signal line SUn extends). The medium-longitudinal direction is between the adjacent light-emitting sheet assemblies 21 and between the adjacent light-emitting sheet assemblies 资料 in the arrangement direction of the data signal lines S1 to Sn. The liquid crystal panel 1 uses a scanning signal line driving circuit. 2. The data signal line drive circuit 3 and the counter electrode drive circuit 4 are driven. The scan signal line drive circuit 2 sequentially selects one scan signal line from the wiper 33 signal lines G1 to Gm and selects the selected scan signal. The signal line application TFT 11 is in an on-state potential: the data signal line drive circuit 3 applies a potential corresponding to the image signal line to the data signal line, and the counter electrode drive circuit 4 applies a specific potential to the counter electrode. Alternatively, a relatively high potential and a relatively low potential are alternately applied. Further, all or a part of the driving circuits may be formed on the liquid crystal panel 1. Fig. 3 is a plan view of the liquid crystal panel. In the middle, a TFT substrate 1 is described The layout of the crucible and the arrangement position of the crucible sheet assembly 21 (indicated by thick lines). In Fig. 3, in addition to the arrangement position of the filter assembly 21, there is also a black matrix 22. Below, attention is focused on the data signal. The black matrix 22 between the adjacent filter elements 21 in the alignment direction of the line § 1 to " will be described. Figure 4 is a cross-sectional view taken along line V-V' of Figure 3. In Fig. 4, a data line 13 formed on the tft earth plate 10 and a black matrix 22 provided on the opposite substrate are described. As shown in FIG. 4, the TFT substrate 1A and the opposite substrate 2 are bonded to each other. 159230.doc 201222086=ΓΓ22 covers the data signal line. At this time, it is preferable to make the central axis of the black matrix 22 and the data signal line. ~ Axis coincides. Thereby, even if a deviation occurs in the bonding of the substrate, the decrease in the elbow opening ratio is limited to the minimum limit. The following is a description of the width of the black matrix 22, which is Χ, and the data signal line 13 is The width is expressed as Υ, and the sum of the two widths (χ+γ) is expressed as eight. Further, (X - Υ) / 2 is referred to as a one-side protrusion amount, and the liquid crystal panel of the present invention is not Bβ. The following three conditions are satisfied: (1) The width of the black matrix is 7 or less. (2) The black matrix on each side is flat. See the width of the poor line. The width of the line is 1 μηι or more. (3) The sum of the width of the black matrix and the width of the data signal line is above the claw. When the central axis of the black matrix 22 coincides with the central axis of the data signal line 13, 'when the range of the above three conditions is satisfied in the XY plane, the inside of the triangular PQR shown in FIG. 5 (the towel, The coordinates of the vertices including the triangles on the boundary line are P(5.5, 3.5), Q(7, 2), R(7, 5). As an example of satisfying the above three conditions (χ, Y), (5 5 μιη, 3 The case of 5 pm) is referred to as Example i. The case of (6 μηι ' 3 μπι) is referred to as the embodiment. The case of (7 μηι ' 4 μηι) is referred to as Embodiment 3. In FIG. 5, Example 1 is 3 corresponds to point ρ, point s, and point τ, respectively. Fig. 6 is a view showing two widths and performances of the liquid crystal panel of the prior art and the present invention. Fig. 6 shows that black matrix is measured or evaluated for seven kinds of liquid crystal panels. Width X, data signal line width γ, width sum Α, one-sided protrusion amount • 59230.doc 201222086 B, aperture ratio, contrast and squint stain results. Furthermore, the aperture ratio depends on the structure of the base, so In order to compare the aperture ratio, it is necessary to make the pixel pitch uniform. The aperture ratio and implementation described in Figure ό The pixel pitch of 2 (the pixel pitch of the arrangement direction of the data line is 2 5.5 μηι, and the pixel pitch of the scanning signal line is 76.5 μιη) is calculated. In the previous example 1, the width of the black matrix is 8 μηι. In the previous example 2, the width of the data signal line is 7.2 μm. Thus, in the previous examples 1, 2, the width of the black matrix and the width of the data signal line are wider, and thus the aperture ratio is lowered. Further, in the previous example 2, The width of the data signal line (7 2 μΓη) is wider than the width of the black matrix (5·3 μιη). Therefore, in the previous example 2, part of the light scattered at the data signal line end is not blocked by the black matrix. The front side is emitted, so the brightness is increased and the contrast is lowered in the black display. In the previous example 3, the aperture ratio becomes the highest and no squint stain is generated. However, in the previous example 3, as will be described later (refer to FIG. 7) In the example 4, the aperture ratio is the highest, and the contrast ratio is higher than that of the previous example 3, but the squint stain is generated. Thus, in the previous examples 1 to 4, the aperture cannot be made. The aperture ratio, the contrast ratio, and the color reproducibility are all improved at the same time. In the embodiment 1, the width of the black matrix is 5.5 μm, and the width of the data signal line is 3.5 μm » in the embodiment 1 'to satisfy the above three conditions ( Among the X ' Υ), the opening ratio becomes the highest. In the first embodiment, the contrast is high (refer to the description of Fig. 7), and no squint stain is generated. Therefore, according to the example 1, the one can be fully raised. The aperture ratio is improved, and the contrast and color reproducibility are improved. 159230.doc 201222086 In the second embodiment, the width of the black matrix is 6 μm, and the width of the data signal line is 3 μm. In Example 2, the one-sided protrusion amount is large to 1.5 μm. Therefore, light that scatters at the end of the data signal line even if the substrate is misaligned is easily blocked by the black matrix. Therefore, according to the second embodiment, the aperture ratio is lowered as compared with the first embodiment, but the contrast can be improved as compared with the first embodiment. In Example 3, the width of the black matrix is 7 μΓη, and the width of the data signal line is 4 μπι. In the third embodiment, the 'unilateral protrusion amount τ is the same as that of the second embodiment'. The width of the line 5 is wider than that of the embodiment 2. Therefore, according to the embodiment 3', the contrast of the same degree as that of the embodiment 2 can be improved. The width of the data signal line is enlarged as compared with the second embodiment. In the high-definition liquid crystal panel A, since the charging time of the data signal line is short, it is necessary to enlarge the width of the data signal line to reduce the load of the data signal line. Embodiment 3 is suitable, for example, in such a case. Further, in the third embodiment, when the width of the data signal line is expanded from 3 μm to 4 μm in preference to the contrast, the width of the black matrix is expanded from 6 μm to 7 μm. Alternatively, even if the aperture ratio is prioritized and the width of the data k-line is increased from 3 μm to 4 μm, the width of the black matrix can be maintained at 6 μηι 〇 or less. The reason for determining the above three conditions will be explained. First, the first condition will be described. In the current color filter, if the width of the black matrix is less than 5 μm, the variation in line width becomes large and the characteristics become unstable.

However, in such a liquid crystal panel, contrast or color reproducibility causes problems. Further, even if the width of the black matrix is wider than 7 μm, the contrast does not increase correspondingly, but the aperture ratio is lowered, so that the overall performance is lowered. Therefore, in the liquid crystal panel of the present invention, a margin of 2 μm is added to a minimum value of 5 μm, and a width of the black matrix is set to be less than 7 μηι. Next, the second condition will be described. Fig. 7 is a graph showing the relationship between the amount of protrusion on one side and the degree of contrast. Fig. 7 shows the results of contrast when the width of the solid black matrix is measured for five liquid crystal panels and the width of the data signal line is changed. The horizontal axis represents the amount of one-sided protrusion Β ’ vertical axis represents contrast. The contrast is the value obtained by dividing the brightness measured on the front side in the white display by the brightness measured on the front side in black. Further, in Fig. 6 and Fig. 7, the configuration of the liquid crystal panel for measuring the object is different. As shown in Fig. 7, there is a significant difference in the contrast ratio when the amount of protrusion on one side is 〇5 μm and the contrast ratio when the amount of one-side protrusion is 1 。. On the other hand, there is no significant difference between the contrast when the one-side protrusion amount is 1 (four) and the contrast ratio when the one-side protrusion amount is 5 (four). Therefore, in order to realize a high contrast liquid crystal panel, it is preferable to set the one-side protrusion amount to be! (4) Above. Therefore, in the liquid crystal panel of the present invention, the width of the black matrix of the disk ".1" Ψ ^ Pc ^ . is larger than the width of the data signal line by more than 1 μm. Next, the third condition will be described. In a typical LCD panel, the deviation of the substrate is about 3 μηη. The distance between the black matrix and the data U line (distance from the direction perpendicular to the panel surface) is approximately $μιη 'the insulating layer between the black matrix and the data signal line and the liquid crystal. 159230.doc •11· 201222086 Refractive index In the liquid crystal panel of 1.5 β for 8 μιη, if the substrate is bonded, the black matrix and the data signal line are observed from the front.

Therefore, if the sum of the widths is a deviation of 8 μm 3 μη, if there is a gap of 1 μπ or more, the observer will tilt 33 from the front in the liquid crystal panel. When viewed in the above direction, excellent spots can be identified. In a liquid crystal panel having a width Α of 9 μm, if a deviation of 3 μm is generated when the substrate is bonded, the overlap between the black matrix and the data signal line when viewed from the front is 1.5 μm. If you are inclined 26 from the front. When the liquid crystal panel is viewed in the above direction, a gap can be seen between the black matrix and the data signal line. Moreover, it is inclined 42 from the front. When the liquid crystal panel is viewed in the direction, the size of the gap is 1 μm. Therefore, in the liquid crystal panel, the tilt 40 is from the front. When viewed in the above direction, excellent spots are recognized. Generally, the tongue 'in the liquid crystal display device' will be about 3 inches from the front. The range within the range is set as the standard observation direction. In a liquid crystal panel having a width Α of 9 μm, it is only limited to recognize excellent spots when the standard viewing direction is greatly exceeded, so that color reproducibility is better. Therefore, in the liquid crystal panel of the present invention, the sum of the width of the black matrix and the width of the data signal line is set to 9 μm or more. In the liquid crystal panel of the present invention, the aperture ratio can be increased by making the width of the black matrix 7 μm or less. Further, by making the width of the black matrix on each side wider than the width of the data signal line by 1 μπι or more, the contrast can be improved. 159230.doc 201222086 Further, by making the sum of the width of the black matrix and the width of the data signal line 9 μηι or more, the color reproducibility can be improved. As described above, the liquid crystal panel 1 (liquid crystal display device) of the present invention is formed by bonding two substrates, and includes a TFT substrate 1 (first substrate) including a plurality of pixels arranged in a two-dimensional manner. a circuit pij and a plurality of data signal lines S1 to Sn arranged in parallel with each other; and a counter substrate 2 (second substrate) including a plurality of filter elements 21 corresponding to the pixel circuit Pij and a data signal disposed at The black matrix 22 between the adjacent filter assemblies 21 in the direction in which the lines S1 to Sn are arranged. The TFT substrate 1A and the opposite substrate 20 are bonded such that the black matrix 22 covers the data signal line 13. The width of the black matrix 22 is 7 μm or less, and the width of the black matrix 22 on each side is larger than the data signal line 1. The width of 3 is wider than 1 μηι, and the sum of the width of the black matrix 22 and the width of the data signal line U is 9 μηι or more. By thus determining the width of the black matrix and the width of the data signal line, it is possible to provide a liquid crystal display device excellent in aperture ratio, contrast, and color reproducibility. [Industrial Applicability] The liquid crystal display device of the present invention is excellent in aperture ratio, contrast, and color reproducibility, and thus can be used in various electronic device display devices and the like.
