It should be noted that in the following description, only the parts necessary for understanding the operation according to the present disclosure are described, and descriptions of other parts are omitted to avoid obscuring the subject matter of the present disclosure. In addition, the present disclosure may be embodied in other forms and is not limited to the embodiments described herein. However, the embodiments described herein are intended to be described in sufficient detail so that those skilled in the art of the present disclosure can easily realize the technical spirit of the present disclosure.
[0040] Throughout the specification, when a part is "connected" to another part, the situation not only includes the situation that the part is "directly connected" to the other part, but also includes the situation that the part is "indirectly connected" to the other part and another element is inserted between the part and the other part. The terms used in this article are used to describe specific embodiments and are not intended to limit the present disclosure. Throughout the specification, when a certain part "includes...", unless otherwise stated, the situation means that the part can also include another component, without excluding another component. "At least any one of X, Y and Z" and "at least any one of the group consisting of X, Y and Z" can be interpreted as any combination of two or more of X, Y and Z (such as XYZ, XY, YZ and XZ). In this article, "and / or" includes all combinations of one or more in the corresponding configuration.
[0041] In this document, terms such as first and second may be used to describe various components, but the components are not limited to these terms. These terms are used to distinguish one component from another. Therefore, a first component can refer to a second component within a scope without departing from the scope disclosed herein.
[0042] For descriptive purposes, spatially relative terms such as "under," "over," and the like may be used herein to describe the relationship between one element or feature and another element(s) or feature(s) as shown in the accompanying drawings. In addition to the directions depicted in the accompanying drawings, spatially relative terms are intended to include other directions in use, operation, and / or manufacture. For example, when the device shown in the figures is inverted, elements described as being "under" other elements or features are positioned in a direction "over" the other elements or features. Thus, in an embodiment, the term "under" may include both directions, over and under. Additionally, the device may be facing other directions (e.g., rotated 90 degrees or in other directions), and therefore, the spatially relative terms used herein are interpreted accordingly.
[0043] Various embodiments are described with reference to the accompanying drawings, which schematically illustrate idealized embodiments. Therefore, it is expected that shapes may vary depending on, for example, tolerances and / or manufacturing techniques. Therefore, the embodiments disclosed herein should not be construed as limited to the specific shapes shown and should be construed to include variations in shape that may occur, for example, due to manufacturing.

[0096] However, the embodiments of the present disclosure are not limited thereto. The first to eighteenth sub-pad groups PAD1 to PAD18 may be arranged in the same manner as Figure 4 and Figure 5 The forms shown are arranged differently in the individual rows and columns.
[0097] Figure 6 It shows that according to the embodiment Figure 1 Figure 1. Output pad unit TOP.
[0098] refer to Figure 6 The output pad unit TOP may include a plurality of sub-pad groups and dummy pads. For example, the output pad unit TOP may include the first to thirteenth sub-pad groups PAD1 to PAD13 and the first to fifteenth dummy pads DP1 to DP15. Figure 4The descriptions of the first to thirteenth sub-pad groups PAD1 to PAD13 overlap.
[0099] The pads included in the first to thirteenth sub-pad groups PAD1 to PAD13 may be pads that receive gate driver control signals from the timing controller TC. On the other hand, the dummy pads DP1 to DP15 may be pads that do not receive any signals from the timing controller TC. As used herein, the term "dummy" refers to pads that have the same or similar structure and shape as the pads of each of the first to thirteenth sub-pad groups PAD1 to PAD13 but do not have a substantial function and exist only as a pattern in the output pad unit TOP.
[0100] exist Figure 6 In the embodiment, the first to eighteenth sub-pad groups PAD1 to PAD18 (reference Figure 4 ) in the fourteenth to eighteenth sub-pad groups PAD14 to PAD18 are used as dummy pads, but the present disclosure is not necessarily limited thereto. The number and placement positions of the dummy pads may vary depending on the product.
[0101] Figure 7 yes Figure 6 Magnified view of section X.
[0102] Reference Figure 6 and Figure 7 Each of the pads PAD1a to PAD13c may have a width equal to the first length L1 in the first direction DR1. Furthermore, each of the pads PAD1a to PAD13c may have a width equal to the second length L2 in the second direction DR2. For example, the 10a-th pad PAD10a may have a width equal to the first length L1 in the first direction DR1 and a width equal to the second length L2 in the second direction DR2.
[0103] The pads adjacent to each other in the first direction DR1 may be spaced apart by a third length L3. For example, the 10ath pad PAD10a and the 13ath pad PAD13a may be spaced apart by a third length L3. For example, the 13ath pad PAD13a and the 13bth pad PAD13b may be spaced apart by a third length L3.
[0104] The pads adjacent to each other in the second direction DR2 may be spaced apart by a fourth length L4. For example, the 11c-th pad PAD11c and the 12c-th pad PAD12c may be spaced apart by a fourth length L4. The fourth dummy pad DP4 and the 13a-th pad PAD13a may be spaced apart by a fourth length L4.
[0105] The distance between adjacent pads in the second direction DR2 can be formed to be wider than the distance between adjacent pads in the first direction DR1. In other words, the fourth length L4 can be larger than the third length L3. Therefore, the influence of the electric field caused by the voltage difference between adjacent pads in the second direction DR2 can be smaller than the influence of the electric field caused by the voltage difference between adjacent pads in the first direction DR1.
[0106] The width of each pad in the first direction DR1 can be smaller than the width of each pad in the second direction DR2. In other words, the first length L1 can be smaller than the second length L2. The area facing each other between adjacent pads in the second direction DR2 can be smaller than the area facing each other between adjacent pads in the first direction DR1. Therefore, the influence of the electric field caused by the voltage difference between adjacent pads in the second direction DR2 can be smaller than the influence of the electric field caused by the voltage difference between adjacent pads in the first direction DR1.
[0107] The transmission line TL may include a first portion, a second portion, and a third portion. The first portion of the transmission line TL may be connected to a control signal generator CSG (reference Figure 2 ) and one of the pads included in the sub-pad group. The second portion of the transmission line TL can connect the pads included in the sub-pad group. The third portion of the transmission line TL can be connected between one of the pads included in the sub-pad group and one of the gate pads GPAD_G. For example, the first portion TL13a of the thirteenth transmission line TL13 can connect the control signal generator CSG to the 13a-th pad PAD13a. The second portions TL13b and TL13c of the thirteenth transmission line TL13 can connect the 13a-th pad PAD13a to the 13c-th pad PAD13c. For example, the second portion TL13b can connect the 13a-th pad PAD13a to the 13b-th pad PAD13b, and the second portion TL13c can connect the 13b-th pad PAD13b to the 13c-th pad PAD13c. The third portion TL13d of the thirteenth transmission line TL13 may connect the 13d-th pad PAD13d to one of the gate pads GPAD_G.
[0108] Each sub-pad group can be connected to the gate pad GPAD_G through a different transmission line TL. Figure 7, the tenth sub-pad group PAD10 including the 10c-th pad PAD10c can be connected to the gate pad GPAD_G through the tenth transmission line TL10. The eleventh sub-pad group PAD11 including the 11c-th pad PAD11c can be connected to the gate pad GPAD_G through the eleventh transmission line TL11. The twelfth sub-pad group PAD12 including the 12c-th pad PAD12c can be connected to the gate pad GPAD_G through the twelfth transmission line TL12. The thirteenth sub-pad group PAD13 can be connected to the gate pad GPAD_G through the thirteenth transmission line TL13.
[0109] In addition, each control signal (e.g., gate driver control signal) can be transmitted to the gate pad GPAD_G through a pad included in one of the pad groups. For example, the tenth gate signal can be transmitted to the gate pad GPAD_G through the 10a-th pads PAD10a to PAD10c included in the tenth sub-pad group PAD10. The eleventh gate signal can be transmitted to the gate pad GPAD_G through the 11a-th pads PAD11a to PAD11c included in the eleventh sub-pad group PAD11. The twelfth gate signal can be transmitted to the gate pad GPAD_G through the 12a-th pads PAD12a to PAD12c included in the twelfth sub-pad group PAD12. The thirteenth gate signal can be transmitted to the gate pad GPAD_G through the 13a-th pads PAD13a to PAD13c included in the thirteenth sub-pad group PAD13.
[0110] According to an embodiment, some of the transmission lines TL connected to the adjacent sub-pad groups in the second direction DR2 may be formed in different layers and may overlap with each other in the third direction DR3. For example, the eleventh transmission line TL11 and the twelfth transmission line TL12 may be formed in different layers and may overlap with each other in the third direction DR3.
[0111] Figure 8 It shows Figure 7 FIG. 1 is a diagram of an embodiment of the present invention.
[0112] refer to Figure 7 and Figure 8, voltage differences can be formed between different pads. For example, a first voltage difference V1 can be formed between the 13a-th pad PAD13a and the 10c-th pad PAD10c, which are adjacent to each other in the first direction DR1. A second voltage difference V2 can be formed between the 13a-th pad PAD13a and the 13b-th pad PAD13b, which are adjacent to each other in the first direction DR1. A second voltage difference V2 can be formed between the 13c-th pad PAD13c and the 13b-th pad PAD13b, which are adjacent to each other in the first direction DR1. A third voltage difference V3 can be formed between the first dummy pad DP1 and the 13c-th pad PAD13c, which are adjacent to each other in the first direction DR1. A fourth voltage difference V4 can be formed between the 13a-th pad PAD13a and the fourth dummy pad DP4, which are adjacent to each other in the second direction DR2. A fourth voltage difference V4 can be formed between the 13b-th pad PAD13b and the fifth dummy pad DP5, which are adjacent to each other in the second direction DR2. A fourth voltage difference V4 may be formed between the 13c-th pad PAD13c and the sixth dummy pad DP6 that are adjacent to each other in the second direction DR2.
[0113] Among the first to fourth voltage differences V1 to V4 , the second voltage difference V2 may be smallest in magnitude.
[0114] When the voltage difference between adjacent pads is large, a strong electric field may be generated between them, and thus charge may migrate. Therefore, corrosion of the pads may occur due to the charge transfer. Since corrosion occurring in the pads may cause increased resistance, disconnection, short circuits, joint defects, etc., corrosion may be a cause of reduced reliability of display devices (DD).
[0115] According to an embodiment of the present disclosure, the distance between the pads adjacent in the second direction DR2 can be formed to be wider than the distance between the pads adjacent in the first direction DR1. Therefore, the influence of the electric field caused by the voltage difference between the pads adjacent in the second direction DR2 can be smaller than the influence of the electric field caused by the voltage difference between the pads adjacent in the first direction DR1. For example, the fourth length L4 (refer to the fourth dummy pad DP4) between the 13a pad PAD13a and the fourth dummy pad DP4 is Figure 6 ) may be larger than the third length L3 (reference length L2) between the 13a-th pad PAD13a and the 10c-th pad PAD10c. Figure 6 Therefore, the influence of the electric field between the 13a-th pad PAD13a and the fourth dummy pad DP4 may be smaller than the influence of the electric field between the 13a-th pad PAD13a and the 10c-th pad PAD10c.
[0116] Furthermore, according to an embodiment of the present disclosure, a pad located at the center of the pads included in a sub-pad group may not be affected by an electric field generated by pads adjacent to the pads in the first direction DR1. For example, among the pads included in the thirteenth sub-pad group PAD13, an electric field due to the second voltage difference V2 may occur between the 13b-th pad PAD13b and the 13a-th pad PAD13a. Furthermore, an electric field due to the second voltage difference V2 may occur between the 13b-th pad PAD13b and the 13c-th pad PAD13c. The magnitudes of the electric fields generated between the 13b-th pad PAD13b and each of the pads PAD13a and PAD13c, which are adjacent to each other in the first direction DR1, may be substantially the same, and the directions of the electric fields generated between the 13b-th pad PAD13b and each of the pads PAD13a and PAD13c, which are adjacent to each other in the first direction DR1, may be opposite to each other. Therefore, when the magnitudes and directions of the formed electric fields are considered and summed, the electric field applied to the 13b-th pad PAD13b may be canceled out, thereby being substantially unaffected by the electric field from the pad adjacent in the first direction DR1.
[0117] According to the embodiments of the present disclosure, since the influence of the electric field on the pad is substantially minimized, corrosion occurring in the pad can be reduced. In addition, as the corrosion occurring in the pad is reduced, an increase in resistance in the pad, disconnection, short circuit, bonding defects, etc. can be substantially prevented, and the reliability of the display device can be improved.
