The active device 102 is electrically connected to the corresponding scan line 32 and the corresponding data line 34. The first electrode 104 has The plurality of first slits 106 have a first angle a1 between the extending direction of the first slit 106 and the extending direction of the scanning line 32 (ie, the second direction D2). In other words, the first electrode 104 may include a plurality of first branch electrodes 110, and the first slits 106 are disposed between the two adjacent first branch electrodes 110, that is, the first branch electrodes 110 of the first electrodes 104. Interlaced with the first slits 106. The material of the first electrode 104 may be a transparent conductive material, such as indium tin oxide, indium zinc oxide or other suitable transparent conductive materials, but not limited thereto. Optionally, the first electrode 104 of the sub-pixel SP1 of the embodiment may further have a plurality of second slits 108, and the extending direction of the first slit 106 and the extending direction of the second slit 108 extend in different directions. And the extending direction of the second slit 108 has a second angle a2 between the extending direction of the scanning line 32 (ie, the second direction D2). Similarly, the first electrode 104 may include a plurality of second branch electrodes 112, and The second slit 108 can also be disposed between the two adjacent second branch electrodes 112, but is not limited thereto. For example, the width of the first slit 106 and the second slit 108 of the first electrode 104 may range from about 3.7 micrometers to about 5.5 micrometers, but not limited thereto. In a variant implementation, the sub-pixel SP1 of the embodiment may be a multi-domain sub-pixel, that is, the first electrode 104 of the sub-pixel SP1 may have a first slit 106 and a second The slits of the slits 108 are all different in slit direction, and will not be described herein. In this embodiment, the first angle a1 is substantially equal to the second angle a2, but is not limited thereto.

In addition, the sub-pixel SP1 of the embodiment may further include a second electrode 114, wherein the first electrode 104 and the second electrode 114 are disposed on different patterned conductive electrode layers, and the first electrode 104 and the second electrode 114 are mutually connected to each other. The first electrode 104 is disposed on the second insulating layer 124. In this embodiment, the second electrode 114 is not connected. In detail, the second electrode 114 is disposed between the first insulating layer 122 and the second insulating layer 124. It is a full-surface electrode, but not limited to this. In addition, the active device 102 is electrically connected to the first electrode 104 or the second electrode 114. In this embodiment, the first electrode 104 is a pixel electrode, and is electrically connected to the data line 34 through the active device 102.

In a variant embodiment, the first electrode 104 is a common electrode, and the second electrode 114 is a pixel electrode and is electrically connected to the data line 34 through the active device 102.

In addition, it should be noted that the brightness gray level of the sub-pixel SP1 is determined by the degree of liquid crystal deflection, and the angle is controlled by adjusting the voltage difference between the first electrode 104 and the second electrode 114. In this embodiment, since the first electrode 104 has the first slit 106 and the second slit 108, the voltage of the first branch electrode 110 and the second branch electrode 112 of the first electrode 104 and the voltage of the second electrode 114 A horizontal electric field is generated on the display medium layer 40 through the first slit 106 and the second slit 108. With the normal black sub-pixel SP1, as the intensity of the horizontal electric field decreases, the area corresponding to the first slit 106 and the second slit 108 will show dark lines, so that the brightness of the sub-pixel SP1 The gray scale is reduced.

Please refer to the fifth to sixth figures. FIG. 5 is a schematic diagram showing the relationship between the gray scale and the brightness difference ratio when the slit width of the sub-pixel has a negative error with different first angles and second angles. FIG. 6 is a schematic diagram showing display gray scale and brightness deviation of a slit having a different first angle and a second angle with a positive error in a slit width of a sub-pixel, wherein the slit has a positive error indicating a width of the slit The error causes an increase in width, and the slit has a negative error indicating that the width of the slit is reduced in width due to an error. In the fifth to sixth figures, the line segments E0 and F0 represent the display panel corresponding to the first angle a1 and the second angle a2 being 5 degrees. The line segments E1 and F1 indicate that the first angle a1 and the second angle a2 of the embodiment are The display panel corresponding to 10 degrees, the line segments E2 and F2 represent the display panel corresponding to the first angle a1 and the second angle a2 of the embodiment, and the positive and negative error values are all exemplified by 0.2 micrometers on one side. As shown in FIG. 5, the luminance difference ratio can be defined as "the brightness of the display panel 1 having the width error of the first slit 106 and the second slit 108 and the first slit 106 in the case where the same gray scale is displayed, and The difference in the brightness of the display panel 1 in which the second slit 108 has no width error occupies the ratio of the brightness of the display panel 1 in which the first slit 106 and the second slit 108 have no width error. When the first angle a1 and the second angle a2 are 5 degrees, the display panel 1 having the width error of the first slit 106 has a significant luminance difference ratio with respect to the display panel 1 having no width error of the first slit 106. However, when the first angle a1 and the second angle a2 are 10 or 15 degrees, that is, the display panel 1 of the present embodiment, in the case where the first slit 106 has a width error, there is no comparison with the first slit 106. In the case of the width error, there is no significant difference in luminance ratio. It can be seen that the first electrode 104 of the present embodiment may cause the first slit 106 and the second slit 108 of the first electrode 104 to be reduced by 0.2 micrometer due to the uneven exposure energy or the error caused by the exposure error, but it is not Because of this error, the brightness of the display gray scale changes too much, and thus the brightness difference is reduced. In other words, the first electrode 104 does not affect the liquid crystal efficiency due to the error, thereby affecting the light transmittance. It should be noted that the liquid crystal efficiency can be defined as "the brightness of the white screen divided by the display module including the upper and lower polarizers divided by the brightness of the white screen by the display module including the upper and lower polarizers under the same backlight". In FIG. 5, regardless of the first angle a1 of the first slit 106 and the second angle a2 of the second slit 108 being 10 degrees or 15 degrees, each sub-pixel SP1 displays the same gray level, and each sub-picture The difference ratio between the brightness of the SP1 is less than about 10%. In addition, when the lower gray scale is displayed and each sub-pixel SP1 displays the same gray level, the difference ratio between the brightness of each sub-pixel SP1 is less than about 10%. Preferably, each sub-pixel SP1 displays the same gray level. When the gray scale is between 32 and 96, the difference ratio between the brightness of each sub-pixel SP1 is less than about 10%. More preferably, each sub-pixel SP1 displays the same gray level and the gray level is between 56. When the value is between 72, the difference ratio between the brightness of each sub-pixel SP1 is less than about 10%. As shown in FIG. 6, the first electrode 104 of the present embodiment may cause the first slit 106 and the second slit 108 of the first electrode 104 to increase by 0.2 micrometers due to uneven exposure energy or an error caused by exposure error. However, this error does not cause the brightness of the display gray scale to change too much, thereby reducing the brightness difference. In other words, the first electrode 104 does not affect the liquid crystal efficiency due to the error, thereby affecting the light transmittance. In FIG. 6, regardless of the first angle a1 of the first slit 106 and the second angle a2 of the second slit 108 being 10 degrees or 15 degrees, each sub-pixel SP1 displays the same gray level, and each sub-picture The difference ratio between the brightness of the SP1 is less than about 10%. In addition, when the lower gray level is displayed and the sub-pixels SP1 display the same gray level, the difference ratio between the brightness of each sub-pixel SP1 is less than about 10%. Preferably, when each sub-pixel SP1 displays the same gray level and the gray level is between 32 and 96, the difference ratio between the brightness of each sub-pixel SP1 is less than about 10%, and more preferably, each sub-pixel When the pixel SP1 displays the same gray scale and the gray scale is between 56 and 72, the difference ratio between the brightness of each sub-pixel SP1 is less than about 10%.

When the first electrode 104 of the sub-pixel SP1 of the display panel 1 of the present embodiment causes the slit of the first electrode 104 to increase or decrease due to the uneven exposure energy or the process error caused by the exposure error, the slit angle can be The adjustment reduces the influence of the crease variation caused by the error, so that the difference in luminance between the sub-pixels SP1 generated by the process error is reduced. Therefore, when the display panel 1 is applied to medical use and used to display a picture corresponding to medical information, the picture can be correctly displayed without being affected by the process error, so that the doctor can make an immediate and correct diagnosis.

The display panel of the present invention is not limited to the above embodiment. The sub-pixels of the display panel of other preferred embodiments of the present invention will be sequentially described below, and in order to facilitate the comparison of the differences of the embodiments and simplify the description, the same symbols are used to mark the same components in the following embodiments. And the description of the differences between the embodiments is mainly made, and the repeated parts are not described again.

Please refer to FIG. 7. FIG. 7 is a top view of the active array layer corresponding to a single sub-pixel according to the second embodiment of the present invention. As shown in FIG. 7, the difference between the present embodiment and the first embodiment is that the sub-pixel SP2 of the embodiment further includes a plurality of first light-shielding strips 206, wherein the first light-shielding strips 206 are respectively disposed corresponding to a first slit 106. And extending along the extending direction of the corresponding first slit 106 and overlapping with the corresponding first slit 106, and the width of each first light shielding strip 206 is smaller than the width of the corresponding first slit 106. In addition, the sub-pixel SP2 of the embodiment further includes a plurality of second light-shielding strips 208, and the first electrode 104 further has a plurality of second slits 108 and overlaps with the corresponding second slits 108, and The two slits 108 are different from the extending direction of the first slits 106. The second light-shielding strips 208 are respectively disposed corresponding to the second slits 108, and extend along the extending direction of the corresponding second slits 108. The width of the two light shielding strips 208 is smaller than the width of the corresponding second slits 108. In a variant implementation, the sub-pixel SP2 may be a multi-domain sub-pixel, that is, the first electrode 104 of the sub-pixel SP2 may have a different extending direction from the first slit 106 and the second slit 108. The slits, and the sub-pixels SP2 of the embodiment may further include a light-shielding strip which is different from the extending direction of the first light-shielding strip 206 and the second light-shielding strip 208, and details are not described herein again. In this embodiment, the first light shielding strip 206 and the second light shielding strip 208 may be formed of an opaque material. For example, the first light-shielding strip 206 and the second light-shielding strip 208 can be formed by patterning the same film layer with the scan line 32. Therefore, the first light-shielding strip 206 and the second light-shielding strip 208 are both opaque metals. In addition, in this embodiment, the first light-shielding strips 206 and the second light-shielding strips 208 are not electrically connected to other conductive structures to form a floating state, but are not limited thereto.

In this embodiment, since the first light-shielding strip 206 and the second light-shielding strip 208 are provided, the first electrode 104 of the present embodiment causes the first electrode 104 to be caused by an uneven exposure energy or an error caused by an exposure error. When the slit is enlarged or reduced, the first light-shielding strip 206 and the second light-shielding strip 208 can effectively shield the dark lines, thereby reducing the influence of the dark-segment variation caused by the error, so that in the state of error, each sub-picture The SP2 has the same dark line width under the same gray level, and reduces the brightness difference between the sub-pixels SP2 generated by the process variation under the same gray level, so the brightness of each sub-pixel SP2 is displayed under the same gray level. Close to the same. In addition, in the embodiment, in order to make the first light-shielding strip 206 and the second light-shielding strip 208 more effectively shield the dark lines, the extended length of each of the first light-shielding strips 206 and the corresponding length of the first slit 106 are substantially Similarly, the extension length of each second light-shielding strip 208 is substantially the same as the extension length of the corresponding second slit 108, but is not limited thereto. Another difference between this embodiment and the first embodiment is that the slit angle of the first electrode 104 of the embodiment can be limited by a range of about 10 degrees to about 15 degrees, that is, the first of the first electrodes 104. The angle between the first angle a1 of the slit 106 and the second angle a2 of the second slit 108 may range from about 10 degrees to about 15 degrees, for example, the angle ranges from about 5 degrees to about 15 degrees, but is not limited thereto. However, in the preferred embodiment, the first angle a1 of the first slit 106 of the first electrode 104 and the second angle a2 of the second slit 108 range between about 10 degrees and about 15 degrees. In addition, in the embodiment, the first light-shielding strip 206 and the second light-shielding strip 208 of the sub-pixel SP2 are the widths of the first slit 106 and the second slit 108 of the first electrode 104, and the first light-shielding strip 206 The width of the second light-shielding strip 208 ranges from about 2 microns to about 3 microns, and the width of the first slit 106 and the second slit 108 of the first electrode 104 ranges from about 3.7 microns to about 5.5 microns. It conforms to the design that the width of the light bar is smaller than the width of the slit, but is not limited thereto.

Please refer to FIG. 8. FIG. 8 is a schematic diagram showing the gray scale and luminance deviation of the slit of the sub-pixel of the display panel according to the first embodiment and the second embodiment of the present invention, wherein the error indicates a positive error or a negative error. When the slit has a positive error, it means that the width of the slit is increased due to the error, and when the slit has a negative error, it means that the width of the slit is reduced due to the error. In Fig. 8, the line segment G1 indicates that the slit of the sub-pixel of the display panel of the first embodiment has a negative error (like E1 of Fig. 5), and the line segment G2 indicates the slit of the sub-pixel of the display panel of the second embodiment. With a negative error, the line segment H1 indicates that the slit of the sub-pixel of the display panel of the first embodiment has a positive error (like F1 of FIG. 6), and the line segment H2 indicates that the slit of the sub-pixel of the display panel of the second embodiment has a positive The error is 10 degrees with the angle of the slit, and the positive and negative error values are all exemplified by 0.2 micron on one side. As shown in FIG. 8, the first electrode 104 of the present embodiment may cause the first slit 106 and the second slit 108 of the first electrode 104 to increase or decrease due to uneven exposure energy or an error caused by exposure error. 0.2 micron, but because the first light-shielding strip 206 and the second light-shielding strip 208 effectively shield the dark light of the corresponding first slit 106 and the second slit 108, the influence of the dark-segment variation caused by the error is reduced. Therefore, it is not caused by the error that the brightness of the display gray scale is excessively changed, thereby causing the brightness difference to be reduced. In other words, in the case of a process error, the sub-pixels SP2 have similar dark lines under the same gray level. The width and brightness make the sub-pixels SP2 display the same brightness under the same gray level. In FIG. 8, when each sub-pixel SP2 displays the same gray level, the difference ratio between the brightness of each sub-pixel SP2 is less than about 10%, and further, since the second embodiment is further included than the first embodiment The first light-shielding strip 206 and the second light-shielding strip 208, therefore, the difference ratio between the sub-pixels SP2 brightness of each of the second embodiments is substantially smaller than the sub-pixels in the respective first embodiments with the same error The difference ratio between SP1 brightness, and when the low gray level is displayed, this brightness difference is more obvious than the improvement effect. In addition, when the lower gray scale is displayed and the sub-pixel SP2 displays the same gray scale, the difference ratio between the brightness of each sub-pixel SP2 is less than about 10%. Preferably, each sub-pixel SP2 displays the same gray level and When the gray scale is between 32 and 96, the difference ratio between the brightness of each sub-pixel SP2 is less than about 10%. More preferably, each sub-pixel SP2 displays the same gray level and when the gray level is between 56 When the value is between 72, the difference ratio between the brightness of each sub-pixel SP2 is less than about 10%.

The first electrode 104 of the sub-pixel SP2 of the display panel 1 of the present embodiment may increase or decrease the slit of the first electrode 104 due to uneven exposure energy or a process error caused by an exposure error. The shading strip is arranged in the slit to reduce the influence of the dark line variation caused by the error, so that the difference in brightness between the sub-pixels SP2 generated by the process error is reduced. Therefore, when the display panel 1 is applied to medical use and used to display a picture corresponding to medical information, the picture can be correctly displayed without being affected by the process error, so that the doctor can make an immediate and correct diagnosis.

Please refer to FIG. 9. FIG. 9 is a top view of an active array layer corresponding to a single sub-pixel according to a third embodiment of the present invention. As shown in FIG. 9, the difference between this embodiment and the second embodiment is that the first light-shielding strip 206, the second light-shielding strip 208 and the data line 34 of the sub-pixel SP3 of the embodiment are formed by patterning the same film layer. Therefore, the first light shielding strip 206 and the second light shielding strip 208 are both opaque metals. In this embodiment, since the first light-shielding strip 206 and the second light-shielding strip 208 are provided, the first electrode 104 of the embodiment may cause the first electrode 104 due to uneven exposure energy or an error caused by exposure error. The slit is enlarged or reduced, but the first light-shielding strip 206 and the second light-shielding strip 208 can effectively shield the dark lines, thereby reducing the influence of the dark-streak variation caused by the error, so that each sub-picture generated by the process error The difference in brightness between the prime SP3 is reduced.

In FIG. 10, the black matrix layer 50 is further illustrated. As shown in FIG. 10, the difference between this embodiment and the second embodiment is that the first light-shielding strip 206, the second light-shielding strip 208, and the black matrix layer 50 of the sub-pixel SP4 of the present embodiment are formed by patterning the same film layer. Therefore, the first light shielding strip 206 and the second light shielding strip 208 are all black shading strips. It should be noted that, since the first light-shielding strip 206 and the second light-shielding strip 208 and the black matrix layer 50 are formed by patterning the same film layer, in the embodiment, the black matrix layer 50 is disposed on the first substrate 10. The black matrix layer 50 may also be selectively disposed on the second substrate 20, that is, the display dielectric layer 40 is located between the black matrix layer 50 and the active array layer 30. In this embodiment, since the first light-shielding strip 206 and the second light-shielding strip 208 are provided, the first electrode 104 of the embodiment may cause the first electrode 104 due to uneven exposure energy or an error caused by exposure error. The slit is enlarged or reduced, but the first light-shielding strip 206 and the second light-shielding strip 208 can effectively shield the dark lines, thereby reducing the influence of the dark-streak variation caused by the error, so that each sub-picture generated by the process error The difference in brightness between the SP4 is reduced.

Please refer to FIG. 11. FIG. 11 is a top view of the active array layer corresponding to a single sub-pixel according to the fifth embodiment of the present invention. As shown in FIG. 11 , the display panel 1 of the present embodiment further includes a spacer 510, and the difference between the embodiment and the second embodiment lies in the first light-shielding strip 206 and the second light-shielding strip of the sub-pixel SP5 of the embodiment. 208 and the spacer 510 are formed by patterning the same film layer, and the spacer 510 is located between the first substrate 10 and the second substrate 20. The first light-shielding strip 206 and the second light-shielding strip 208 are both opaque materials. In this embodiment, since the first light-shielding strip 206 and the second light-shielding strip 208 are provided, the first electrode 104 of the embodiment may cause the first electrode 104 due to uneven exposure energy or an error caused by exposure error. The slit is enlarged or reduced, but the first light-shielding strip 206 and the second light-shielding strip 208 can effectively shield the dark lines, thereby reducing the influence of the dark-streak variation caused by the error, so that each sub-picture generated by the process error The difference in brightness between the SP5 is reduced.

In summary, when the electrode of the sub-pixel of the display panel of the present invention is caused by the unevenness of the exposure energy or the process error caused by the exposure error, the slit of the electrode is increased or reduced, and the slit angle can be adjusted or blocked. The setting of the strip is to reduce the influence of the dark-streak variation caused by the error, so that the difference in brightness between the sub-pixels generated by the process error is reduced, thereby correctly displaying the image information, and avoiding the doctor in medical treatment.
