Fig. 1A is a schematic top view of a display panel according to at least one embodiment of the invention. Referring to fig. 1A, the display panel 100 includes a substrate 190 and a plurality of sub-pixels. The substrate 190 may be a transparent plate, such as a glass substrate. The sub-pixels include at least one first sub-pixel 110r and at least two second sub-pixels 120. Although FIG. 1A depicts three subpixels: one first sub-pixel 110r and two second sub-pixels 120, but in other embodiments, the display panel 100 may include more than three sub-pixels including a plurality of first sub-pixels 110 r. Therefore, the number of the first sub-pixel 110r and the second sub-pixel 120 in fig. 1A is only for illustration and is not meant to limit the invention.

The first sub-pixel 110r and the second sub-pixel 120 are disposed on the substrate 190, wherein the first sub-pixel 110r may be a red sub-pixel, and the two second sub-pixels 120 in fig. 1A may be a green sub-pixel and a blue sub-pixel, respectively, but the invention is not limited thereto. The first sub-pixel 110r includes a first pixel electrode 111, wherein the first pixel electrode 111 has two first major axis patterns H11, V11 and a plurality of first oblique patterns S11a, S11b, and the first oblique pattern S11a has a significantly different orientation from the first oblique pattern S11 b.

The first oblique patterns S11a and S11b are respectively connected to at least one of the first main shaft patterns H11 and V11. Taking fig. 1A as an example, the first diagonal patterns S11A and S11b at the edge of the first pixel electrode 111 are each connected to one of the first major axis patterns H11 or V11, and the first diagonal patterns S11A and S11b at the center of the first pixel electrode 111 are respectively connected to the first major axis patterns H11 and V11. In addition, the first pixel electrode 111 may further have a frame-shaped pattern F11 surrounding and connecting the first oblique patterns S11a, S11b and the first major axis patterns H11, V11.

The first sub-pixel 110r may further include a second pixel electrode 112, wherein the second pixel electrode 112 is separated from the first pixel electrode 111, so the second pixel electrode 112 is not directly electrically connected to the first pixel electrode 111. Similar to the structure of the first pixel electrode 111, the second pixel electrode 112 has two second major axis patterns H12 and V12, a plurality of second oblique patterns S12a and S12b, and a frame pattern F12.

The second diagonal patterns S12a and S12b are also respectively connected to at least one of the second main shaft patterns H12 and V12. For example, the second diagonal patterns S12a and S12b at the edge of the second pixel electrode 112 each connect one second major axis pattern H12 or V12, and the second diagonal patterns S12a and S12b at the center of the second pixel electrode 112 each connect second major axis patterns H12 and V12. In addition, the frame pattern F12 surrounds and connects the second diagonal patterns S12a, S12b and the second major axis patterns H12, V12.

In the present embodiment, the first main axis patterns H11, V11, the second main axis patterns H12, V12, the first oblique patterns S11a, S11b, the second oblique patterns S12a, S12b, and the frame patterns F11, F12 may be a solid conductive film layer, which may be a transparent conductive film or a metal layer, and the material of the transparent conductive film may be, for example, Indium Tin Oxide (ITO) or Indium Zinc Oxide (IZO). In addition, in other embodiments, the frame patterns F11 and F12 may be omitted, i.e., the second pixel electrode 112 and the first pixel electrode 111 may not have the frame patterns F11 and F12.

However, in other embodiments, the first main axis pattern H11, V11, the second main axis pattern H12, V12, the first diagonal patterns S11a, S11b, and the second diagonal patterns S12a, S12b may be non-solid slits. In detail, in the first pixel electrode 111, the blank region separating the first oblique patterns S11a and S11b may be a solid conductive film layer and is connected to the frame pattern F11. In the second pixel electrode 112, the empty area separating the second oblique patterns S12a and S12b may also be a solid conductive film layer and connected to the frame pattern F12. Therefore, the first major axis patterns H11, V11, the second major axis patterns H12, V12, the first oblique patterns S11a, S11b, and the second oblique patterns S12a, S12b may be non-solid slits, and are not limited to solid conductive film layers.

Fig. 1B is a schematic top view of the first pixel electrode in fig. 1A. Referring to fig. 1A and 1B, in the first pixel electrode 111, the first main axis patterns H11 and V11 are interleaved to form at least four first regions RU11, LU11, LD11 and RD11, wherein the first regions RU11, LU11, LD11 and RD11 are sequentially arranged from upper right, upper left, lower left and lower right in the normal direction of the substrate 190, and the first oblique patterns S11A and S11B are located in the first regions RU11, LU11, LD11 and RD 11.

In the first regions RU11, LU11, LD11 and RD11, one of the first oblique patterns S11a and S11b and one of the first main axis patterns H11 and V11 have a first included angle AH11, AH12, AV11 or AV12 therebetween. In detail, the first oblique patterns S11a may be substantially parallel to each other, and the first oblique patterns S11b may be substantially parallel to each other. A first included angle AH11 is formed between each of the first diagonal patterns S11a and the first major axis pattern H11, and a first included angle AV11 is formed between each of the first diagonal patterns S11a and the first major axis pattern V11. A first included angle AH12 is formed between each of the first diagonal patterns S11b and the first major axis pattern H11, and a first included angle AV12 is formed between each of the first diagonal patterns S11b and the first major axis pattern V11.

In the embodiment shown in fig. 1B, both the first principle axis patterns H11 and V11 are substantially perpendicular, and the dashed line in fig. 1B is equal to the bisector of the angle between the first principle axis patterns H11 and V11. Therefore, the included angles SA1 formed between the first main axis patterns H11 and V11 and the dashed lines in the figure are equal to each other, and each included angle SA1 is substantially equal to 45 degrees.

As shown in fig. 1B, the first angles AH12 and AV12 may be located together in the same first region LU11 or RD11, and the first angles AH11 and AV11 may be located together in the same first region RU11 or LD11, wherein the absolute values (i.e. the magnitudes of the angles) of the first angles AH12 and AV12 are significantly different, and the absolute values of the first angles AH11 and AV11 are significantly different.

For example, in FIG. 1B, the first angle AV12 is equal to the angle SA1 plus the angle M1, i.e., the absolute value of the first angle AV12 is about (45+ M), where M is the absolute value of the angle M1, and M is greater than or equal to-12 and less than or equal to 12. First included angle AH12 is equal to included angle SA1 minus angle M1, i.e., first included angle AH12 is approximately (45-M) in absolute value. Therefore, the absolute value of the first included angle AH12 is significantly different from the absolute value of the first included angle AV 12.

Likewise, the absolute values of the first included angles AH11 and AV11 are significantly different. First included angle AV11 is equal to included angle SA1 minus angle M1, i.e., first included angle AV11 has an absolute value of about (45-M). First included angle AH11 is equal to included angle SA1 plus angle M1, i.e., first included angle AH11 is about (45+ M) absolute. Therefore, the first included angle AH11 is also significantly different from the first included angle AV 11.

It can be seen that the absolute values of the first angles AV11 and AH12 are both about (45-m), and the absolute values of the first angles AV12 and AH11 are both about (45+ m), so the absolute values of the first angles AV11 and AH12 can be substantially equal to each other, and the absolute values of the first angles AV12 and AH11 can be substantially equal to each other.

The first included angles AV11 and AH11 exist in the same upper right first region RU11, the first included angles AV12 and AH12 exist in the same upper left first region LU11, the first included angles AV11 and AH11 exist in the same lower left first region LD11, and the first included angles AV12 and AH12 exist in the same lower right first region RD 11. That is, the absolute values of the first angles AH11 and AV11 of the upper-right first region RU11 may be substantially the same as the absolute values of the first angles AH11 and AV11 of the lower-left first region LD11, respectively, and the absolute values of the first angles AH12 and AV12 of the upper-left first region LU11 may be substantially the same as the absolute values of the first angles AH12 and AV12 of the lower-right first region RD11, respectively.

The absolute value of the first angle (e.g. first angle AH11, AH12, AV11 or AV12) of one of the two adjacent first regions (e.g. first regions RU11, RD11, LU11 and LD11) is different from the absolute value of the first angle of the other of the two adjacent first regions. Taking fig. 1B as an example, the first region LU11 is adjacent to RU11, wherein the absolute value of the first included angle AH12 in the first region LU11 is different from the absolute value of the first included angle AH11 in the first region RU 11. Similarly, first region RU11 is adjacent to RD11, where the absolute value of first angle AV11 within first region RU11 is different from the absolute value of first angle AV12 within first region RD 11.

Next, the sum of the absolute value of the first angle (e.g. the first angle AH11, AH12, AV11 or AV12) of one of the two adjacent first regions (e.g. the first regions RU11, RD11, LU11 and LD11) and the absolute value of the first angle of the other of the two adjacent first regions is about an orthogonal angle, wherein the orthogonal angle may be between 85 and 95 degrees, preferably 90 degrees, due to the error.

Taking fig. 1B as an example, in the adjacent first areas LU11 and RU11, the absolute value of the first included angle AV12 in the first area LU11 is (45+ m), and the absolute value of the first included angle AV11 in the first area RU11 is (45-m). Therefore, the sum of the absolute values of the first included angles AV11 and AV12 can be 90 degrees, i.e., the above-mentioned orthogonal angles. Similarly, in the adjacent first regions RU11 and RD11, the absolute value of the first included angle AH11 in the first region RU11 is (45+ m), and the absolute value of the first included angle AH12 in the first region RD11 is (45-m). Therefore, the sum of the absolute values of the first included angles AH11 and AH12 can also be orthogonal angles, such as 90 degrees.

Based on the above, since the sum of absolute values of two adjacent first angles (e.g., the first angles AV11 and AV12) in two adjacent first regions (e.g., the first regions LU11 and RU11) is about an orthogonal angle (about 85 to 95 degrees, preferably 90 degrees), gray scales of the first pixel electrode 111 in the horizontal direction (substantially parallel to the extending direction of the first main axis pattern H11) and the vertical direction (substantially parallel to the extending direction of the first main axis pattern V11) are consistent without an excessive difference, and the color difference of the image at different viewing angles (e.g., the vertical and horizontal directions) is reduced.

In addition, the absolute value of the first included angle of one of the two adjacent first areas and the absolute value of the first included angle of the other of the two adjacent first areas are different by about 24 degrees. For example, since the absolute value of the first included angle AV12 in the first region LU11 is (45+ m) and the absolute value of the first included angle AV11 in the first region RU11 is (45-m) in the adjacent first regions LU11 and RU11, the difference between the first included angles AV11 and AV12 may be about 2m degrees. Since m can be equal to-12 or 12, the difference between the first angles AV11 and AV12 can be about 24 degrees (2 × 12).

In the embodiment shown in fig. 1B, the first spindle pattern H11 passes between the upper right first region RU11 and the lower right first region RD11, and between the upper left first region LU11 and the lower left first region LD 11. In other words, the first major axis pattern H11 may extend along the horizontal direction. In contrast, the first spindle pattern V11 passes between the upper right first region RU11 and the upper left first region LU11, and between the lower right first region RD11 and the lower left first region LD11, i.e., the first spindle pattern H11 may extend in the vertical direction.

It should be noted that, although the first spindle patterns H11 and V11 shown in fig. 1B extend along the horizontal direction and the vertical direction, respectively, in other embodiments, the first spindle patterns H11 and V11 may also extend along other directions and do not extend along the horizontal direction and the vertical direction, so the first spindle patterns H11 and V11 shown in fig. 1B do not limit the present invention.

Since the absolute values of the first included angles AH11, AH12, AV11 and AV12 formed by the first oblique patterns S11a and S11b and the first main axis patterns H11 and V11 are (45+ m) or (45-m), the first oblique patterns S11a and S11b do not have mirror symmetry with the first main axis pattern H11 or V11 as a symmetry axis, so as to reduce the influence of the boundary electric field of the first pixel electrode 111, thereby helping to weaken the color cast phenomenon that the display image changes colors with different viewing angles.

In addition, the four arrangements of the first regions RU11, LU11, LD11 and RD11 shown in fig. 1B are for illustration only. In other embodiments, the first regions RU11, LU11, LD11 and RD11 may be arranged in other manners to change the arrangement of the first oblique patterns S11a and S11 b. For example, the first regions RU11, LU11, LD11 and RD11 in fig. 1B are reversed upside down. Alternatively, the first regions RU11, LU11, LD11 and RD11 are arranged in order from upper left, upper right, lower right and lower left.

Fig. 1C is a schematic top view of the second pixel electrode in fig. 1A. Referring to fig. 1A and 1C, the second pixel electrode 112 has a shape different from the first pixel electrode 111, wherein the second pixel electrode 112 has a substantially rectangular shape, a long axis thereof is substantially parallel to a vertical direction (as shown in fig. 1C), and the first pixel electrode 111 has a substantially square shape. However, the second pixel electrode 112 is similar to the first pixel electrode 111 in terms of structure. In addition, in other embodiments, the shape of the second pixel electrode 112 may also be the same as the shape of the first pixel electrode 111.

Specifically, in a single second pixel electrode 112, the second main axis patterns H12 and V12 are interleaved to form at least four second regions RU12, LU12, LD12 and RD12, and the second oblique patterns S12a and S12b are all located in the second regions RU12, LU12, LD12 and RD12 and are respectively connected to at least one of the corresponding second main axis patterns H12 and V12.

In the normal direction of the substrate 190, these second regions RU12, LU12, LD12 and RD12 are arranged in order from upper right, upper left, lower left and lower right, wherein the second main shaft pattern H12 passes between the upper right second region RU12 and the lower right second region RD12, and between the upper left second region LU12 and the lower left second region LD12, and the second main shaft pattern V12 passes between the upper right second region RU12 and the upper left second region LU12, and between the lower right second region RD12 and the lower left second region LD 12. Taking fig. 1C as an example, the second major axis pattern H12 may extend along the horizontal direction, and the second major axis pattern V12 may extend along the vertical direction.

The second diagonal patterns S12a may be substantially parallel to each other, and the second diagonal patterns S12b may also be substantially parallel to each other. A second included angle AH21 is formed between each of the second diagonal patterns S12a and the second major axis pattern H12, and a second included angle AV21 is formed between each of the second diagonal patterns S12a and the second major axis pattern V12. A second included angle AH22 is formed between each of the second diagonal patterns S12b and the second major axis pattern H12, and a second included angle AV22 is formed between each of the second diagonal patterns S12b and the second major axis pattern V12.

In the embodiment shown in fig. 1C, the second major axis patterns H12 and V12 are both substantially perpendicular, and the dashed line is equal to the bisector of the angle between the second major axis patterns H12 and V12. Therefore, the two angles SA1 formed between the second main axis patterns H12 and V12 and the dashed lines are equal to each other, and each angle SA1 is substantially equal to 45 degrees.

In fig. 1C, the second included angles AH22 and AV22 may be located together in the same second region LU12 or RD12, and the second included angles AH21 and AV21 may be located together in the same first region RU12 or LD12, wherein the absolute values of the second included angles AH22 and AV22 are significantly different, and the absolute values of the second included angles AH21 and AV22 are significantly different.

For example, in FIG. 1C, the second angle AV22 is equal to the angle SA1 minus the angle N2, i.e., the absolute value of the second angle AV22 is about (45-N), where N is the absolute value of the angle N2, and N is greater than or equal to-12 and less than or equal to 12. Second angle AH22 is equal to angle SA1 plus angle N2, i.e., second angle AH22 is about (45+ N) absolute. It can be seen that second angle AH22 is significantly different from second angle AV 22.

Likewise, the absolute values of the second included angles AH21 and AV21 are significantly different. Second angle AV21 is equal to angle SA1 plus angle N2, i.e., second angle AV21 has an absolute value of about (45+ N). Second included angle AH21 is equal to included angle SA1 minus angle N2, i.e., second included angle AH21 is approximately (45-N) in absolute value. Therefore, the second included angle AH22 is also significantly different from the second included angle AV 22. Since the absolute values of both the second angles AV22 and AH21 are about (45-n) and the absolute values of both the second angles AV21 and AH22 are about (45+ n), the absolute values of both the second angles AV21 and AH22 may be equal and the absolute values of both the second angles AV22 and AH21 may be equal.

Next, the same second region RU12 has second included angles AV21 and AH21, the same second region LU12 has second included angles AV22 and AH22, the same second region LD12 has second included angles AV21 and AH21, and the same second region RD12 has second included angles AV22 and AH22, so that absolute values of the second included angles AH21 and AV21 of the upper right second region RU12 may be substantially the same as absolute values of the second included angles AH21 and AV21 of the lower left second region LD12, and absolute values of the second included angles AH22 and AV22 of the upper left second region LU12 may be substantially the same as absolute values of the second included angles AH22 and AV22 of the lower right second region RD 12.

The absolute value of the second angle (e.g. second angle AH21, AH22, AV21 or AV22) of one of two adjacent second regions (e.g. second region RU12, RD12, or LU12 and LD12) is different from the absolute value of the second angle of the other of the two adjacent second regions.

Taking fig. 1C as an example, the second region LU12 is adjacent to RU12, wherein the absolute value (45+ n) of the second included angle AH22 in the second region LU12 is different from the absolute value (45-n) of the second included angle AH21 in the second region RU 12. Likewise, second region RU12 is adjacent to RD12, where the absolute value of second angle AV21 (45+ n) in second region RU12 is different from the absolute value of second angle AV22 (45-n) in second region RD 12.

Then, the sum of the absolute value of the second angle of one of the two adjacent second regions and the absolute value of the second angle of the other of the two adjacent second regions is about an orthogonal angle, wherein the orthogonal angle may be between 85 and 95 degrees, preferably 90 degrees, due to the error.

Taking fig. 1C as an example, in the adjacent second areas LU12 and RU12, the absolute value of the second included angle AV22 in the second area LU12 is (45-n), and the absolute value of the second included angle AV21 in the second area RU12 is (45+ n). Therefore, the sum of the absolute values of the second included angles AV21 and AV22 can be 90 degrees, i.e., the above-mentioned orthogonal angle. Similarly, in the adjacent second regions RU12 and RD12, the absolute value of the second included angle AH21 in the second region RU12 is (45-n), and the absolute value of the second included angle AH22 in the second region RD12 is (45+ n). Therefore, the sum of the absolute values of the second included angles AH21 and AH22 can also be orthogonal angles, such as 90 degrees.

Since the sum of absolute values of two adjacent second angles (e.g., the second angles AV21 and AV22) in two adjacent second regions (e.g., the second regions LU12 and RU12) is about an orthogonal angle, the gray scales of the second pixel electrode 112 in the horizontal direction and the vertical direction are substantially consistent to reduce the color shift of the displayed image, as in the first pixel electrode 111 of the previous embodiment.

In addition, the absolute value of the second included angle of one of the two adjacent second areas is about 24 degrees different from the absolute value of the second included angle of the other of the two adjacent second areas. For example, since the absolute value of the second included angle AV22 in the second region LU12 is (45-n) and the absolute value of the second included angle AV21 in the second region RU12 is (45+ n) in the adjacent second regions LU12 and RU12, the difference between the second included angles AV21 and AV22 may be about 2n degrees. Since n can be equal to-12 or 12, the difference between the second angles AV21 and AV22 can be about 24 degrees (2 × 12).

It should be noted that the four arrangements of the second regions RU12, LU12, LD12 and RD12 shown in fig. 1C are only for illustration. In other embodiments, the second regions RU12, LU12, LD12 and RD12 may be arranged in other manners to change the arrangement of the second oblique patterns S12a and S12 b. For example, the second regions RU12, LU12, LD12 and RD12 in fig. 1C are reversed upside down. Alternatively, the second regions RU12, LU12, LD12 and RD12 are arranged in order from upper left, upper right, lower right and lower left.

Referring to fig. 1A to 1C, in the first sub-pixel 110r, the first angle AV12 of the first region RD11 located at the lower right position is adjacent to the second angle AV21 of the second region RU12 located at the upper right position. When m is substantially equal to n, the absolute value of the first angle AV12 of the lower right first region RD11 is (45+ m), and the absolute value of the second angle AV21 of the upper right second region RU12 is (45+ m), so the first angles AV12 and AV21 are substantially equal to each other. In other words, the first included angle AV12 of the lower right first region RD11 is adjacent to and substantially identical to the absolute value of the second included angle AV21 of the upper right second region RU 12.

Similarly, when m is substantially equal to n, the absolute value of the first angle AV11 of the lower left first region LD11 is (45-m), and the absolute value of the second angle AV22 of the upper left second region LU12 is (45-m), so the first angles AV11 and AV22 are substantially equal to each other. In other words, the first angle AV11 of the first lower-left region LD11 is adjacent to and substantially the same as the absolute value of the second angle AV22 of the second upper-left region LU 12.

In the embodiment shown in fig. 1A, the first sub-pixel 110r includes a first pixel electrode 111 and a second pixel electrode 112, wherein the first pixel electrode 111 and the second pixel electrode 112 can respectively generate four fields (4domains), so the first sub-pixel 110r can have eight fields. However, in other embodiments, the first sub-pixel 110r may have only four fields, and one of the first pixel electrode 111 and the second pixel electrode 112 in the first sub-pixel 110r may be omitted, that is, the first sub-pixel 110r includes the first pixel electrode 111 or the second pixel electrode 112.

Under the condition that the first sub-pixel 110r has only four fields, the first sub-pixel 110r includes only one first pixel electrode 111 or one second pixel electrode 112. When the first subpixel 110r includes only one first pixel electrode 111, m of the absolute values (45 ± m) of the above-described first included angles cannot be equal to zero. When the first subpixel 110r includes only one first pixel electrode 111, m of the absolute values (45 ± m) of the above-described first included angles cannot be equal to zero. Similarly, when the first sub-pixel 110r includes only one second pixel electrode 112, n of the absolute values (45 ± n) of the first included angle may not be equal to zero.

Fig. 1D is a schematic top view of the second sub-pixel in fig. 1A. Referring to fig. 1A and fig. 1D, the second sub-pixels 120 include at least two third pixel electrodes 123 and at least two fourth pixel electrodes 124. Taking fig. 1A as an example, each of the second sub-pixels 120 includes a third pixel electrode 123 and a fourth pixel electrode 124. The third pixel electrodes 123 respectively have two third major axis patterns H3 and V3, wherein the third major axis patterns H3 and V3 alternately form at least four third regions R3. For example, in FIG. 1D, the third major axis patterns H3 and V3 may be substantially perpendicular to each other, wherein the third major axis pattern H3 may extend along the horizontal direction and the third major axis pattern V3 may extend along the vertical direction.

Similar to the first pixel electrode 111, each of the third pixel electrodes 123 further has a plurality of third oblique patterns S3a and S3b, wherein the third oblique patterns S3a and S3b are located in the third regions R3 and are respectively connected to at least one of the third main axis patterns H3 and V3, wherein the third oblique patterns S3a may be substantially parallel to each other, and the third oblique patterns S3b may be substantially parallel to each other. In addition, the third pixel electrode 123 may further have a frame-shaped pattern F3 surrounding and connecting the third oblique patterns S3a, S3b and the third major axis patterns H3, V3. However, the third pixel electrode 123 of other embodiments may not have the frame pattern F3, so the frame pattern F3 may be omitted.

In the embodiment shown in FIG. 1D, the third primary axis pattern H3 and V3 form an orthogonal angle therebetween. Unlike the first sub-pixel 110r, the third diagonal patterns S3a and S3b may extend along the bisector of the orthogonal angle. As seen in fig. 1A, the extending direction of the third diagonal pattern S3a is different from the extending direction of the first diagonal pattern S11A or the second diagonal pattern S12a, and the extending direction of the third diagonal pattern S3b is different from the extending direction of the first diagonal pattern S11b or the second diagonal pattern S12 b. Therefore, the arrangement of the liquid crystal molecules on the third pixel electrode 123 is obviously different from the arrangement of the liquid crystal molecules on the first pixel electrode 111 or the second pixel electrode 112, and the color shift phenomenon of the displayed image is effectively reduced or eliminated.

In each third region R3, an absolute value of a third included angle A3 is formed between one of the third oblique patterns S3a and S3b and one of the third main axis patterns H3 and V3, and an absolute value of a third included angle A3 in one of the two adjacent third regions R3 is the same as an absolute value of a third included angle A3 in the other one of the two adjacent third regions R3.

In detail, unlike the first sub-pixel 110R, the third angles A3 in the third pixel electrode 123 may be substantially equal to each other, and an absolute value of each of the third angles A3, for example, an absolute value of one of the third angles A3 in two adjacent third regions R3, may be about (45 ± p) degrees, where p may be an error and may be about 0-5. Since the third angles a3 can be substantially equal to each other, the third diagonal patterns S3a and S3b can be substantially mirror-symmetrical with the third main axis pattern H3 or V3 as a symmetry axis, as shown in fig. 1D.

The fourth pixel electrode 124 is different from the third pixel electrode 123 only in shape, but the fourth pixel electrode 124 is similar to the third pixel electrode 123 in structure. Specifically, the fourth pixel electrodes 124 respectively have two fourth main axis patterns H4 and V4, wherein the fourth main axis patterns H4 and V4 are staggered to form at least four fourth regions R4. The fourth spindle patterns H4 and V4 may be substantially perpendicular to each other, wherein the fourth spindle pattern H4 may extend along the horizontal direction, and the fourth spindle pattern V4 may extend along the vertical direction, as shown in fig. 1D. In addition, in other embodiments, the shape of the fourth pixel electrode 124 may also be the same as the shape of the third pixel electrode 123, such as a square.

The fourth pixel electrodes 124 also have a plurality of fourth oblique patterns S4a and S4b, respectively, wherein the fourth oblique patterns S4a and S4b are located in the fourth regions R4 and are respectively connected to at least one of the corresponding fourth main axis patterns H4 and V4, wherein the fourth oblique patterns S4a may be substantially parallel to each other, and the fourth oblique patterns S4b may be substantially parallel to each other. In addition, the fourth pixel electrode 124 may further have a frame-shaped pattern F4 surrounding and connecting the fourth diagonal patterns S4a, S4b and the fourth major axis patterns H4, V4. However, the fourth pixel electrode 124 of other embodiments may not have the frame pattern F4, so the frame pattern F4 may be omitted.

The fourth major axis patterns H4 and V4 form an orthogonal angle therebetween, and the fourth diagonal patterns S4a and S4b may extend along the bisector of the orthogonal angle. Therefore, one of the fourth diagonal patterns S4a and S4b and one of the fourth major axis patterns H4 and V4 in each fourth region R4 have an absolute value of a fourth included angle a4 therebetween, and the fourth included angles a4 in the fourth pixel electrode 124 may be substantially equal to each other, wherein the absolute value of each fourth included angle a4 may be about (45 ± p) degrees, and p may be an error. Therefore, the fourth diagonal patterns S4a and S4b may also be mirror images of the fourth main axis pattern H4 or V4 as a symmetry axis.

In addition, the third main axis patterns H3, V3, the fourth main axis patterns H4, V4, the third oblique patterns S3a, S3b, the fourth oblique patterns S4a, S4b, and the frame-shaped patterns F3, F4 may be solid conductive film layers. Alternatively, the third main axis patterns H3, V3, the fourth main axis patterns H4, V4, the third diagonal patterns S3a, S3b, and the fourth diagonal patterns S4a, S4b may be non-solid slits. Therefore, the third main axis patterns H3, V3, the fourth main axis patterns H4, V4, the third oblique patterns S3a, S3b, and the fourth oblique patterns S4a, S4b are not limited to be only solid conductive film layers.

It should be noted that, when the first sub-pixel 110r has eight fields, the first sub-pixel 110r includes the first pixel electrode 111 and the second pixel electrode 112, and one of m and n may be equal to zero, but m and n cannot be zero at the same time. That is, when m is zero, n must not be zero. Conversely, when n is zero, m must not be zero. For example, under the condition that the first sub-pixel 110r has eight fields, the structure of the first pixel electrode 111 may be replaced with the same or similar structure as the third pixel electrode 123, but the second pixel electrode 112 remains unchanged. Alternatively, the second pixel electrode 112 structure may be replaced with the same or similar to the fourth pixel electrode 124 structure, but the first pixel electrode 111 remains unchanged.

Fig. 2 is a schematic top view of a first sub-pixel in another embodiment of the invention. Referring to fig. 2, the first sub-pixel 210r may include a first pixel electrode 111 and a second pixel electrode 212, wherein the second pixel electrode 212 has two second major axis patterns H12, V12 and a plurality of second oblique patterns S21, S22, wherein the second major axis patterns H12 and the second major axis patterns V12 are interlaced to form at least four second regions RU2, LU2, LD2 and RD2, and the direction of the second oblique pattern S21 is different from the direction of the second oblique pattern S22. In addition, the second diagonal patterns S21 and S22 are located in the second regions RU2, LU2, LD2 and RD 2.

The second oblique patterns S21 and S22 form second angles AH31 and AH32 with the second main axis pattern H12, respectively, and each of the second oblique patterns S21 and S22 forms second angles AV31 and AV32 with the second main axis pattern V12, respectively, wherein the absolute values of the second angles AV31 and AH32 are about (45-n), respectively, and the absolute values of the second angles AV32 and AH31 are about (45+ n), respectively.

Under the condition that m is equal to n, the sum of the absolute value (45-m) of the first included angle AH12 of the lower right first region RD11 and the absolute value (45+ n) of the second included angle AH31 of the upper right second region RU2 is about an orthogonal angle, and the sum of the absolute value (45+ m) of the first included angle AH11 of the lower left first region LD11 and the absolute value (45-n) of the second included angle AH32 of the upper left second region LU2 is about an orthogonal angle.

In addition, under the condition that m is equal to n, the sum of the absolute value (45-m) of the first included angle AV11 of the upper-right first region RU11 and the absolute value (45+ n) of the second included angle AV32 of the lower-right second region RD2 is about an orthogonal angle, and the sum of the absolute value (45-m) of the first included angle AH12 of the upper-left first region LU11 and the absolute value of the second included angle AH31(45+ n) of the lower-left second region LD2 is about an orthogonal angle.

Based on the above, when m is equal to n, the absolute value (45-m) of the first included angle AH12 located in the lower right first region RD11 is different from the absolute value (45+ n) of the second included angle AH31 located in the upper right second region RU2 by about 24 degrees. Similarly, the difference between the absolute value (45+ m) of the first included angle AH11 located in the lower left first region LD11 and the absolute value (45-n) of the second included angle AH32 located in the upper left second region LU2 is about 24 degrees.

Furthermore, the absolute value (45+ m) of the first included angle AH11 located in the upper right first region RU11 is about 24 degrees different from the absolute value (45-n) of the second included angle AH32 located in the lower right second region RD2, and the absolute value (45+ m) of the first included angle AV12 located in the upper left first region LU11 is about 24 degrees different from the absolute value of the second included angle AV31 located in the lower left second region LD 2.

In addition, the first angle AV11 of the first region LD11 located at the lower left position is adjacent to and different from the absolute value of the second angle AV32 of the second region LU2 located at the upper left position. The first angle AH11 of the upper right first region RU11 is adjacent to and different from the absolute value of the second angle AH32 of the lower right second region RD2, and the first angle AH12 of the upper left first region LU11 is different from the absolute value of the second angle AH31 of the lower left second region LD 2.

In summary, since the absolute value of the first included angle formed by the first oblique pattern and the first major axis pattern is (45 ± m), where-12 ≦ m ≦ 12, the color shift phenomenon that the display image changes color with different viewing angles is reduced. In addition, since the extending direction of the oblique pattern (such as the first or second oblique pattern) in the first sub-pixel is different from the extending direction of the oblique pattern (such as the third or fourth oblique pattern) in the second sub-pixel, the arrangement mode of the liquid crystal molecules in the first sub-pixel is obviously different from that in the second sub-pixel, thereby effectively weakening or eliminating the color cast phenomenon of the displayed image.

Although the present invention has been described with reference to particular embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
