Hereinafter, a relationship between the black matrix layer  21  and the color resist layer in the electronic device of the present embodiment are described with  FIG.  4    accompanying with  FIG.  2    and  FIG.  5 A . The electronic device of the present embodiment comprises: a first substrate  1  (as shown in  FIG.  1   ); a second substrate  2  (as shown in  FIG.  1   ) opposite to the first substrate  1 ; a black matrix layer  21  disposed between the first substrate  1  and the second substrate  2  and comprising a first pixel region Rp 1  and a first shielding region Rs 1 , wherein the first pixel region Rp 1  and the first shielding region Rs 1  are disposed alternately along a first direction Y, and the first pixel region Rp 1  comprises a first sub-pixel opening  211 ; a scan line  11  disposed between the first substrate  1  and the second substrate  2 , wherein the scan line  11  extends along a second direction X, the first direction Y is different from the second direction X, and the first shielding region Rs 1  overlaps the scan line  11 ; a first pixel color resist  221  disposed corresponding to the first sub-pixel opening  211 ; and a first color resist  231  disposed in the first shielding region Rs 1 . In one embodiment, a width dx′ of the first color resist  231  at the second direction X can be greater than a width d 1  of the first pixel color resist  221  at the second direction X, wherein the width d 1  of the first pixel color resist  221  at the second direction X refers to a distance between two ends of the first pixel color resist  221  on the black matrix layer  21  in a cross section along the second direction X, and the width dx′ of the first color resist  231  at the second direction X refers to a distance between two ends of the bottom of the first color resist  231  in a cross section along the second direction X. In another embodiment, a width dx′ of the first color resist  231  at the second direction X can be greater than a width d 2  of the first sub-pixel opening  211  at the second direction X, wherein the width d 2  of the first sub-pixel opening  211  refers to a distance between two ends of the first sub-pixel opening  211  at the bottom of the first sub-pixel opening  211  in a cross section along the second direction X. In the present embodiment, a color of the first pixel color resist  221  is the same as a color of the first color resist  231 , and the first pixel color resist  221  connects to the first color resist  231 . 
     As the display device with high resolution becomes the mainstream display device in the market, the size of the first sub-pixel opening  211  is getting smaller, and the size of the first pixel color resist  221  is also getting smaller. The pigment contained in the first pixel color resist  221  may absorb light, wherein the surface layer of the first pixel color resist  221  absorb more exposure light, and the bottom layer of the first pixel color resist  221  absorb less exposure light. In this situation, the photo color resist at the bottom layer of the first pixel color resist  221  may react incompletely because the exposure energy absorbed by the bottom layer of the first pixel color resist  221  is insufficient during the photolithography process, resulting in the adhesion decreased or the undercut. Thus, the first pixel color resist  221  may be peeled off. 
     In the present embodiment, the width dx′ of the first color resist  231  at the second direction X in the first shielding region Rs 1  is designed to be greater than the width d 1  of the first pixel color resist  221  at the second direction X in the first pixel region Rp 1 , so that the area of the first color resist  231  is increased. In another embodiment, the width dx′ of the first color resist  231  at the second direction X in the first shielding region Rs 1  is designed to be greater than the width d 2  of the first sub-pixel opening  211  at the second direction X in the first pixel region Rp 1 , so that the area of the first color resist  231  is increased. Because the color of the first pixel color resist  221  is the same as the color of the first color resist  231  and the first pixel color resist  221  connects to the first color resist  231 , the first pixel color resist  221  and the first color resist  231  can be formed at the same time by a single opening of a mask. In the present embodiment, an opening area of the mask is increased as the area of the first color resist  231  increased. When a photo color resist is used to form the first color resist  231  and the first pixel color resist  221 , the total exposure energy is increased as the total light amount is increased by enlarging the opening area of the mask. Thus, the photo color resist can react completely, and the overall adhesion of the first color resist  231  and the first pixel color resist  221  can further be improved. The first color resist  231  can assist the fixing of the first pixel color resist  221  because the color of the first pixel color resist  221  is the same as the color of the first color resist  231  and the first pixel color resist  221  connects to the first color resist  231 . Meanwhile, the overall adhesion of the first color resist  231  and the first pixel color resist  221  can be improved by increasing the adhesion area of the first color resist  231 . Even though the area of the first pixel color resist  221  is small, the adhesion of the first color resist  231  with the larger area can decrease the peeling possibility of the first pixel color resist  221 . 
     In the present disclosure, the width dx′ of the first color resist  231  at the second direction X is designed to be greater than the width d 1  of the first pixel color resist  221  at the second direction X or the width d 2  of the first sub-pixel opening  211  at the second direction X to achieve the aforesaid effect. In one embodiment of the present disclosure, the width dx′ of the first color resist  231  at the second direction X is greater than or equal to 1.5 times of the width d 1  of the first pixel color resist  221  at the second direction X (dx′/d 1 ≥1.5) and less than a width of the second substrate  2 . In another embodiment, the width dx′ of the first color resist  231  at the second direction X can be greater than or equal to 1.5 times of the width d 2  of the first sub-pixel opening  211  at the second direction X (dx′/d 2 ≥1.5) and less than the width of the second substrate  2 . In the present embodiment, the width dx′ of the first color resist  231  at the second direction X is greater than or equal to 2 times of the width d 1  of the first pixel color resist  221  at the second direction X and less than the width of the second substrate  2 . In another embodiment, the width dx′ of the first color resist  231  at the second direction X is greater than or equal to 2 times of the width d 2  of the first sub-pixel opening  211  at the second direction X and less than the width of the second substrate  2 . But, the present disclosure is not limited thereto. 
     As shown in  FIG.  2    and  FIG.  4   , in the present embodiment, the first pixel region Rp 1  may further comprises a second sub-pixel opening  212 , the second pixel color resist  222  is disposed corresponding to the second sub-pixel opening  212 , a color of the second pixel color resist  222  is the same as the color of the second color resist  232 , the second pixel color resist  222  connects to the second color resist  232 , and a width dx′ of the second color resist  232  at the second direction X is greater than a width d 1  of the second pixel color resist  222  at the second direction X. In addition, the feature of the second sub-pixel opening  212  can be the same as the feature of the first sub-pixel opening  211 , i.e. a width dx′ of the second color resist  232  at the second direction X is greater than a width d 2  of the second sub-pixel opening  212  at the second direction X. The width d 2  of the second sub-pixel opening  212  is not shown in the figure, but can be referred to the width d 2  of the first sub-pixel opening  211  shown in  FIG.  5 A . In another embodiment, the width dx′ of the second color resist  232  at the second direction X can be greater than or equal to 1.5 times of the width d 2  of the second sub-pixel opening  212  at the second direction X.

In addition, the feature of the third sub-pixel opening  213  can be the same as the feature of the first sub-pixel opening  211 , i.e. a width dx′ of the fourth color resist  233  at the second direction X is greater than a width d 2  of the third sub-pixel opening  213  at the second direction X. The width d 2  of the third sub-pixel opening  213  is not shown in the figure, but can be referred to the width d 2  of the first sub-pixel opening  211  shown in  FIG.  5 A . In another embodiment, the width dx′ of the fourth color resist  233  at the second direction X can be greater than or equal to 1.5 times of the width d 2  of the third sub-pixel opening  213 . In the present embodiment, the relation between the second pixel color resist  222  and the second color resist  232  and/or the relation between the third pixel color resist  223  and the fourth color resist  233  can be the same as or similar to the relation between the first pixel color resist  221  and the first color resist  231 , and is not repeated again. 
     In addition, as shown in  FIG.  2    and  FIG.  4   , the disposition position of the first color resist  231 , the second color resist  232  and the fourth color resist  233  of the first shielding region Rs 1  cannot be exposed from the first sub-pixel opening  211 , the second sub-pixel opening  212  and the third sub-pixel opening  213 . In other words, a width dy′ of the first color resist  231 , the second color resist  232  and the fourth color resist  233  of the first shielding region Rs 1  at the first direction Y has to be equal to or smaller than a width D BM  of the first shielding region Rs 1  at the first direction Y (dy′≤D BM ).

The first pixel region Rp 1  of the black matrix layer  21  is disposed between the first pixel color resist  221  and the second pixel color resist  222 , between the second pixel color resist  222  and the third pixel color resist  223 , and also between the first pixel color resist  221  and the third pixel color resist  223 . In addition, the first pixel color resist  221 , the second pixel color resist  222  and the third pixel color resist  223  may cover a part of the first pixel region Rp 1 . In another embodiment of the present disclosure, the first pixel color resist  221 , the second pixel color resist  222  and the third pixel color resist  223  may not cover the first shielding region Rs 1 .

More specifically, the width w is greater than or equal to 0% of the width d 1  and less than 50% of the width d 1  (0%≤(w/d 1 )×100%&lt;50%), the width w is greater than or equal to 0% of the width d 1  and less than 40% of the width d 1  (0%≤(w/d 1 )×100%&lt;40%), the width w is greater than or equal to 0% of the width d 1  and less than 30% of the width d 1  (0%≤(w/d 1 )×100%&lt;30%), the width w is greater than or equal to 0% of the width d 1  and less than 20% of the width d 1  (0%≤(w/d 1 )×100%&lt;20%), or the width w is greater than or equal to 0% of the width d 1  and less than 10% of the width d 1  (0%≤(w/d 1 )×100%&lt;10%). In another embodiment, the width w of the overlapping region R at the second direction X can be greater than or equal to 0 and less than 50% of the width d 2  (as shown in  FIG.  5 A ) of the first sub-pixel opening  211  at the second direction X. More specifically, the width w is greater than or equal to 0% of the width d 2  and less than 50% of the width d 2  (0%≤(w/d 2 )×100%&lt;50%), the width w is greater than or equal to 0% of the width d 2  and less than 40% of the width d 2  (0%≤(w/d 2 )×100%&lt;40%), the width w is greater than or equal to 0% of the width d 2  and less than 30% of the width d 2  (0%≤(w/d 2 )×100%&lt;30%), the width w is greater than or equal to 0% of the width d 2  and less than 20% of the width d 2  (0%≤(w/d 2 )×100%&lt;20%), or the width w is greater than or equal to 0% of the width d 2  and less than 10% of the width d 2  (0%≤(w/d 2 )×100%&lt;10%). Even not shown in the figure, two adjacent first color resist  231  and second color resist  232  or two adjacent second color resist  232  and fourth color resist  233  can be overlapped in the first shielding region Rs 1  to form another overlapping region. The relation between the width w of this overlapping region and the width d 1  or between the width w of this overlapping region and the width d 2  are similar to that described above, and is not repeated again. 
     In the present embodiment, because the first color resist  231 , the second color resist  232  and the fourth color resist  233  are disposed in the first shielding region Rs 1 , the color mixing problem is not occurred even though the first color resist  231 , the second color resist  232  and the fourth color resist  233  are overlapped. When two adjacent first color resist  231  and second color resist  232  are overlapped, two adjacent second color resist  232  and fourth color resist  233  are overlapped or two adjacent first color resist  231  and fourth color resist  233  are overlapped, the adhesion between the color resists can be improved by the partial overlapping of two adjacent color resists. Thus, the peeling problem of the color resists can be prevented. 
     As shown in  FIG.  5 C , the first pixel color resist  221  and the first color resist  231  are adjacent and have the same color, so the first color resist  231  can assist the fixing of the first pixel color resist  221  to reduce the peeling probability of the first pixel color resist  221 . Similarly, even not shown in the figure, in other cross section of the present embodiment, the second pixel color resist  222  and the second color resist  232  are adjacent and have the same color and the third pixel color resist  223  and the fourth color resist  233  are adjacent and have the same color, so the peeling probability of the second pixel color resist  222  and the third pixel color resist  223  can also be reduced. 
       FIG.  6    is a schematic view showing a color resist layer in an electronic device according to another embodiment of the present disclosure. The electronic device of the present embodiment is similar to that shown in  FIG.  3   , except for the pattern of the color resist layer. 
     In the present embodiment, the color resists of the first shielding region Rs 1  only comprise the first color resist  231  and the second color resist  232 . The first color resist  231  and the first pixel color resist  221  have the same color and connect to each other. The width dx′ of the first color resist  231  at the second direction X is 4 times of the width d 1  of the first pixel color resist  221  at the second direction X. The second color resist  232  and the second pixel color resist  222  have the same color and connect to each other. The width dx′ of the second color resist  232  at the second direction X is 2 times of the width d 1  of the second pixel color resist  222  at the second direction X.

     Furthermore, in the present embodiment, the black matrix layer (not shown in the figure) further comprise a second shielding region Rs 2 , and the first shielding region Rs 1 , the first pixel region Rp 1  and the second shielding region Rs 2  are disposed alternately along the first direction Y, and the first pixel region Rp 1  is disposed between the first shielding region Rs 1  and the second shielding region Rs 2 . The electronic device of the present embodiment further comprises a third color resist  234  disposed in the second shielding region Rs, a color of the third color resist  234  is the same as the color of the first pixel color resist  221 , the third color resist  234  connects to the first pixel color resist  221 , and a width dx′ of the third color resist  234  at the second direction X is greater than the width d 1  of the first pixel color resist  221  at the second direction X. For example, the width dx′ of the third color resist  234  at the second direction X is greater than or equal to 1.5 times of the width d 1  of the first pixel color resist  221  at the second direction X. In the present embodiment, the width dx′ of the third color resist  234  at the second direction X is 2 times of the width d 1  of the first pixel color resist  221  at the second direction X. In another embodiment, the width dx′ of the third color resist  234  at the second direction X can be greater than the width d 2  of the first sub-pixel opening  211  at the second direction X. For example, the width dx′ of the third color resist  234  at the second direction X is greater than or equal to 1.5 times of the width d 2  of the first sub-pixel opening  211  at the second direction X. In the present embodiment, the width dx′ of the third color resist  234  at the second direction X is 2 times of the width d 2  of the first sub-pixel opening  211  at the second direction X. 
     In the present embodiment, for the first pixel color resist  221 , the first shielding region Rs 1  and the second shielding region Rs 2  at two sides of the first pixel color resist  221  are respectively disposed with the first color resist  231  and the third color resist  234 , which have the same color as the first pixel color resist  221  and connects to the first pixel color resist  221 . Hence, the first color resist  231  and the third color resist  234  disposed at two sides of the first pixel color resist  221  can assist the fixing of the first pixel color resist  221  to reduce the peeling probability of the first pixel color resist  221 . Similarly, the design of the second pixel color resist  222  is the same as that of the first pixel color resist  221 , and is not repeated again. In the present embodiment, the first pixel color resist  221 , the first color resist  231  and the third color resist  234  are red color resists, the second pixel color resist  222  and the second color resist  232  are green color resists, and the third pixel color resist  223  is a blue color resist. But, the present disclosure is not limited thereto.

In the present embodiment, the overall adhesion of the first pixel color resist  221  can be improved by the first color resist  231 , and the overall adhesion of the second pixel color resist  222  can be improved by the second color resist  232 . Thus, the peeling probability of the first pixel color resist  221  and the second pixel color resist  222  can be reduced. Even though the area of the first pixel color resist  221  is small, the adhesion of the first pixel color resist  221  can be increased by increasing the color resist area with the first color resist  231  having larger adhesion area, so that the peeling probability of the first pixel color resist  221  can be reduced. Similarly, even though the area of the second pixel color resist  222  is small, the adhesion of the second pixel color resist  222  can be increased by increasing the color resist area with the second color resist  232  having larger adhesion area, so that the peeling probability of the second pixel color resist  222  can be reduced. 
     In the present embodiment, the widths dx′ of the first color resist  231  and the third color resist  234  at the second direction X are 1.5 times of the width d 1  of the first pixel color resist  221  at the second direction X, and the width dx′ of the second color resist  232  at the second direction X is 1.5 times of the width d 1  of the second pixel color resist  222  at the second direction X.

Thus, the peeling probability of the first pixel color resist  221  and the second pixel color resist  223  can be reduced. Even though the area of the first pixel color resist  221  is small, the adhesion of the first pixel color resist  221  can be improved by increasing the color resist area with the first color resist  231  having larger adhesion area, so that the peeling probability of the first pixel color resist  221  can be reduced. Similarly, even though the area of the second pixel color resist  222  is small, the adhesion of the second pixel color resist  222  can be improved by increasing the color resist area with the second color resist  232  having larger adhesion area, so that the peeling probability of the second pixel color resist  222  can be reduced.

When the first pixel color resist  221  has to have larger adhesion than the third pixel color resist  223  due to the material property of the first pixel color resist  221 , even though the area of the first pixel color resist  221  is small, the adhesion of the first pixel color resist  221  can be improved by increasing the color resist area with the first color resist  231  having larger adhesion area, so that the peeling probability of the first pixel color resist  221  can be reduced. Similarly, when the second pixel color resist  222  has to have larger adhesion than the third pixel color resist  223  due to the material property of the second pixel color resist  222 , even though the area of the second pixel color resist  222  is small, the adhesion of the second pixel color resist  222  can be improved by increasing the color resist area with the second color resist  232  having larger adhesion area, so that the peeling probability of the second pixel color resist  222  can be reduced. 
     In the present embodiment, the width dx′ of the first color resist  231  at the second direction X is 2 times of the width d 1  of the first pixel color resist  221  at the second direction X, but the width dx′ of the second color resist  232  at the second direction X is the same as the width d 1  of the second pixel color resist  222  at the second direction X.
