[0048] The present invention will now be described more fully hereinafter with reference to the accompanying drawings in which various embodiments are shown. However, the present invention may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the scope of the invention to those skilled in the art.

[0049] The terms used in this article are only for the purpose of describing specific embodiments and are not intended to limit. As used in this article, "one", "the (described)" and "at least one" do not represent the limitation of quantity, and are intended to include both the singular and the plural, unless the context clearly indicates otherwise. Therefore, in the claims, the reference to "one" element is followed by the reference to "described" element and includes one element and multiple elements. For example, "one element" has the same meaning as "at least one element", unless the context clearly indicates otherwise. "At least one" should not be interpreted as limiting "one". "Or" means "and / or". As used in this article, the term "and / or" includes any and all combinations of one or more of the associated listed items. Throughout this disclosure, the expression "at least one of a, b and c" or "at least one selected from a, b and c" means only a, only b, only c, a and b both, a and c both, b and c both, a, b and c all or its variant.

[0050] While the present disclosure is capable of various modifications and alternative forms, embodiments thereof are shown by way of example in the drawings and will herein be described in detail. Figure 1 The effects and characteristics of the present disclosure and methods of achieving them will become apparent from the embodiments described in detail below. However, the present disclosure is not limited to the embodiments disclosed below and can be implemented in various forms.

[0051] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings. In the description with reference to the accompanying drawings, the same reference numerals are given to the same or substantially the same elements, and the description will not be repeated.

[0052] In the embodiments described below, when an element such as a layer, film, region, plate, or the like is referred to as being "on" another element, the reference may indicate not only that the element is "directly" "on" the other element, but also that another element is between the element and the other element. Furthermore, elements in the drawings may have exaggerated or reduced dimensions for ease of illustration and description. For example, the dimensions and thicknesses of elements in the drawings are arbitrarily indicated for ease of illustration and description, and therefore, the present disclosure is not necessarily limited to the illustrations in the drawings.

[0053] In the embodiments below, the x-axis, y-axis, and z-axis are not limited to the three axes of the rectangular coordinate system and can be interpreted in a broader sense. For example, the x-axis, y-axis, and z-axis can be perpendicular to each other, or can represent different directions that are not perpendicular to each other.

[0054] It will be understood that although the terms "first", "second", etc. may be used herein to describe various components, these components should not be limited by these terms. These components are only used to distinguish one component from another.

[0055] It will be further understood that when used herein, the terms “include” and / or “comprises” and variations thereof specify the presence of stated features, regions, integers, steps, operations, elements and / or parts, but do not preclude the presence or addition of one or more other features, regions, integers, steps, operations, elements, parts and / or groups thereof.

[0056] In the present specification, the expression "A and / or B" may mean A, B, or A and B. In addition, the expression "at least one of A and B" or "at least one selected from A and B" may indicate A, B, or A and B.

[0057] In the embodiments below, it will be understood that when a layer, region, or element is referred to as being connected to another layer, region, or element, it can be directly or indirectly connected to the other layer, region, or element. For example, it will be understood in this specification that when a layer, region, or element is referred to as being in contact with or electrically connected to another layer, region, or element, it can be directly or indirectly in contact with or electrically connected to the other layer, region, or element.

[0058] In addition, relative terms such as "lower" or "bottom" and "upper" or "top" may be used herein to describe the relationship of one element to another element as illustrated in the figures. It will be understood that relative terms are intended to cover different orientations of the device in addition to the orientation depicted in the figures. For example, if the device in one of the figures is turned over, the element described as being on the "lower" side of the other elements will then be oriented on the "upper" side of the other elements. Thus, depending on the specific orientation of the figure, the term "lower" can cover both the "lower" and "upper" orientations. Similarly, if the device in one of the figures is turned over, the element described as being "below" or "beneath" the other elements will then be oriented "above" the other elements. Thus, the term "below" or "below" can include both the above and below orientations.

[0059] As used herein, "about" or "approximately" are inclusive of the stated value and mean within an acceptable range of deviation for that particular value as determined by one of ordinary skill in the art, taking into account the measurements in question and the errors associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, "about" can mean within one or more standard deviations, or within ±30%, 20%, 10%, or 5% of the stated value.

[0060] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those skilled in the art to which the present disclosure belongs. It will be further understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an idealized or overly formal sense unless explicitly defined as such herein.

[0061] The embodiments are described herein with reference to schematic cross-sectional illustrations of ideal embodiments. Therefore, variations in the shapes of the illustrations as a result of, for example, manufacturing techniques and / or tolerances are contemplated. Therefore, the embodiments described herein should not be interpreted as being limited to the specific shapes of the regions as illustrated herein, but rather are intended to include deviations in shapes, for example, resulting from manufacturing. For example, a region illustrated or described as flat may typically have rough and / or nonlinear features. In addition, illustrated sharp corners may be rounded. Therefore, the regions illustrated in the figures are schematic in nature, and their shapes are not intended to illustrate the precise shape of the regions and are not intended to limit the scope of the claims.

The first light shielding portion 511 can be arranged at the -x side relative to the 1-1 upper opening UOP1-1 (for example, between the 1-1 upper opening UOP1-1 and the 2-1 upper opening UOP2-1). The second light shielding portion 512 can be arranged at the +y side relative to the 1-1 upper opening UOP1-1 (for example, between the 1-1 upper opening UOP1-1 and the 2-2 upper opening UOP2-2).

The fourth light shielding portion 514 may be arranged at the -y side relative to the 1-1st upper opening UOP1-1 in substantially the same manner as the second light shielding portion 512. The fifth light shielding portion 515 may be arranged between adjacent second upper openings UOP2. In an embodiment, for example, a portion of the fifth light shielding portion 515 may be arranged between the 2-1st upper opening UOP2-1 and the 2-2nd upper opening UOP2-2.

[0126] The widths of the first to fifth light-shielding portions 511 to 515 may differ from one another.

However, the present disclosure is not limited to having Figure 5 The number and arrangement of color filters as shown in FIG. The number, shape and / or area of the color filters 520 may be variously changed.

[0129] refer to Figure 6 , the first to third sub-organic light emitting diodes OLEDs1, OLEDs2, and OLEDs3 may be arranged in the sub-display area SDA. The characteristics and operating principles of each of the first to third sub-organic light emitting diodes OLEDs1, OLEDs2, and OLEDs3 may be the same as those described above. Figure 3 The main organic light emitting diode OLEDm( Figure 3 ) have the same characteristics and operating principles.

[0130] A spacer SPC may be disposed between the first sub-organic light emitting diode OLEDs1 and the second sub-organic light emitting diode OLEDs2. The spacer SPC may be disposed between the second sub-organic light emitting diode OLEDs2 and the third sub-organic light emitting diode OLEDs3. The spacer SPC may define a region between the sub-organic light emitting diodes so that a deposition material deposited in each sub-organic light emitting diode does not overflow into an adjacent sub-organic light emitting diode during a deposition process.

[0131] The light shielding layer 510 may not be arranged in the auxiliary display area SDA. Figure 3), in the sub-display area SDA, the first to third color filters 521 to 523 may be directly disposed on the upper surface of the touch layer 400. In an embodiment, for example, the third color filter 523 may overlap with the third sub-organic light emitting diode OLEDs3 and may be disposed on the upper surface of the second touch insulating layer 440. The first color filter 521 may overlap with the first sub-organic light emitting diode OLEDs1 and may be disposed on the second touch insulating layer 440. Here, the first color filter 521 may cover a portion of an edge of the third color filter 523 and a portion of an edge of the light shielding layer 510 (e.g., a third light shielding portion 513). The second color filter 522 may overlap with the second sub-organic light emitting diode OLEDs2 and may be disposed on the second touch insulating layer 440. Here, the second color filter 522 may cover a portion of an edge of the third color filter 523 and a portion of an edge of the light shielding layer 510 (e.g., a third light shielding portion 513). In addition, each of the first color filter 521 and the second color filter 522 may be in direct contact with the upper surface of the second touch insulation layer 440 .

[0132] Some layers may be omitted in the transmission area TA. In an embodiment, for example, the buffer layer 101, the gate insulating layer 103, the interlayer insulating layer 105, the second via layer 109, the bank layer 111, the light shielding layer 510, and the color filter 520 may be omitted in the transmission area TA. In other words, the buffer layer 101, the gate insulating layer 103, the interlayer insulating layer 105, the second via layer 109, and the bank layer 111 may collectively define an opening that overlaps the transmission area TA.

[0133] The first through-hole layer 107 and the organic encapsulation layer 320 may be arranged throughout the sub-display area SDA and the transmission area TA and may have a flat upper surface. The first through-hole layer 107 may directly contact the upper surface of the substrate 100 in the transmission area TA.

[0134] Figure 7A is a plan view of a component area of a display device according to another embodiment. Figure 7B yes Figure 7A An enlarged plan view of region VIIB of the display device.

[0135] refer to Figure 7A and Figure 7BIn an embodiment, a portion of the mesh structure of the light shielding layer 510 may be omitted. In an embodiment, for example, the portion of the light shielding layer 510 disposed between the auxiliary display area SDA and the transmissive area TA may be omitted. Accordingly, a portion of the second touch electrode layer 430 and / or a portion of the dam layer 111 disposed below the light shielding layer 510 may be exposed and / or visible.

[0136] In the examples, reference Figure 7B , in the area where the light shielding layer 510 is omitted, the second touch electrode layer 430 may also be omitted and thus may not be seen. Figure 5 and Figure 7B ,according to Figure 7B In the embodiment shown in FIG, the Figure 5 1-1 upper opening UOP1-1 and the 2-1 upper opening UOP2-1 can be spatially connected to each other. Here, the second touch electrode layer 430 can be omitted where the second touch electrode layer 430 overlaps with the first light shielding portion 511 and the second light shielding portion 512. In other words, the second touch electrode layer 430 may not be arranged in the -x direction and the +y direction relative to the 1-1 upper opening UOP1-1. The embankment layer 111 can be set to overlap with the light shielding layer 510. Therefore, in such an embodiment in which a portion of the light shielding layer 510 is omitted, the second touch electrode layer 430 can also be omitted in the corresponding area, and the embankment layer 111 arranged thereunder can be seen.

[0137] Both the light shielding layer 510 and the embankment layer 111 may include a light absorbing material and, therefore, may be black and may not reflect external light. However, the second touch electrode layer 430 may include a metal and, therefore, may reflect external light. Therefore, in the case where a portion of the light shielding layer 510 is omitted, the second touch electrode layer 430 may reflect external light and may flicker in the corresponding area visible to the user. However, according to an embodiment of the present disclosure, in the case where a portion of the light shielding layer 510 is omitted, a portion of the second touch electrode layer 430 corresponding to the omitted portion of the light shielding layer 510 (or exposed by the omitted portion of the light shielding layer 510) is also omitted, so that the second touch electrode layer 430 cannot be seen and only the embankment layer 111 can be seen, and, therefore, reflection of external light may not occur in the corresponding area and the user cannot see the second touch electrode layer 430.

[0138] However, the present disclosure is not necessarily limited to a structure in which both the light shielding layer 510 and the second touch electrode layer 430 are omitted in a specific area. Figure 7B, although the second touch electrode layer 430 may be omitted, the light shielding layer 510 may not be omitted in the region between the 1-1 upper opening UOP1-1 and the 2-2 upper opening UOP2-2. Figure 7A As illustrated in FIG, although the light shielding layer 510 may be omitted, in some areas, the second touch electrode layer 430 may not be omitted and may be visible.

[0139] Figure 8 It is taken along line VIII-VIII' Figure 7B sectional view of a display device. Figure 9 It is taken along line IX-IX' Figure 7B sectional view of a display device. Figure 10 It is taken along the line X-X' Figure 7B sectional view of a display device.

[0140] According to the characteristics of the floor plan, the above reference Figure 7A and Figure 7B The second touch electrode layer 430 viewed in the +z direction is mainly described. Figure 7A and Figure 7B The described characteristics of the second touch electrode layer 430 may be equally applied to the first touch electrode layer 410 hereinafter.

[0141] refer to Figure 8 , the light shielding layer 510 may not be arranged in some areas (for example, the first area 1A between the transmission area TA and the sub-display area SDA on the -x side). Similarly, the second touch electrode layer 430 and the first touch electrode layer 410 may not be arranged in the first area 1A. Accordingly, the second touch insulating layer 440 and the first touch insulating layer 420 may be in direct contact with each other in the first area 1A. In an embodiment, for example, the upper surface of the first touch insulating layer 420 and the lower surface of the second touch insulating layer 440 may be in direct contact with each other. In addition, the outer coating layer 530 may be in direct contact with the second touch insulating layer 440 in the first area 1A. In an embodiment, for example, the lower surface of the outer coating layer 530 may be in direct contact with the upper surface of the second touch insulating layer 440. However, the embankment layer 111 may be arranged in the first area 1A. Therefore, as Figure 7B As shown in FIG, when the first region 1A is viewed in the +z direction, the bank layer 111 can be seen.

[0142] refer to Figure 9, the second touch electrode layer 430 and the first touch electrode layer 410 may be omitted in some areas (for example, the second area 2A between the transmission area TA and the sub-display area SDA at the +y side). However, the light shielding layer 510 may be arranged in the second area 2A. Accordingly, the lower surface of the second touch insulating layer 440 and the upper surface of the first touch insulating layer 420 may be in direct contact with each other in the second area 2A. However, in the second area 2A, the lower surface of the overcoat layer 530 and the upper surface of the second touch insulating layer 440 may be separated from each other by the light shielding layer 510. Figure 7B As shown in FIG5 , when the second region 2A is viewed in the +z direction, the light shielding layer 510 can be seen.

[0143] refer to Figure 10 , all of the light shielding layer 510, the second touch electrode layer 430, the first touch electrode layer 410 and the bank layer 111 may be arranged in the third area 3A between the transmission areas TA. Figure 7B As shown in FIG5 , when the third region 3A is viewed in the +z direction, the light shielding layer 510 can be seen.

[0144] Figure 11A is a plan view of a component area of a display device according to an embodiment. Figure 11B yes Figure 11A FIG. 1 is an enlarged plan view of a region XIB of the display device. Figure 11C yes Figure 11A An enlarged plan view of the display device region XIC.

[0145] exist Figures 11A to 11C In the embodiment shown in FIG, the light shielding layer is omitted. Figure 11A The embodiment shown in Figure 4 or Figure 7A The same as the embodiment shown in FIG5 in which the light shielding layer is omitted. Figure 11B The embodiment shown in Figure 4 The same as the embodiment shown in FIG. 1 in which the light shielding layer is omitted in region V, or Figure 7A The characteristics of the second touch electrode layer 430 described below are not necessarily limited to the second touch electrode layer 430 and may be applied to the first touch electrode layer 410 as well.

[0146] refer to Figure 11A In an embodiment, the second touch electrode layer 430 may define a first opening OP1 overlapping with the auxiliary display area SDA and a second opening OP2 overlapping with the transmission area TA. Therefore, the first opening OP1 of the second touch electrode layer 430 may overlap with the light shielding layer 510 ( Figure 4 )'s first upper opening UOP1( Figure 4) overlap. In addition, the second opening OP2 of the second touch electrode layer 430 may overlap with the light shielding layer 510 ( Figure 4 )'s second upper opening UOP2( Figure 4 Similar to the light shielding portion of the light shielding layer, the second touch electrode layer 430 may include a line at least partially surrounding the first opening OP1 and the second opening OP2.

[0147] The dam layer 111, disposed below the second touch electrode layer 430, may be provided with a transmissive opening that overlaps each transmissive area TA. The first to third sub-organic light-emitting diodes OLEDs1, OLEDs2, and OLEDs3 may be arranged in the auxiliary display area SDA. The dam layer 111 may be provided with an emission opening that defines an emission area for each of the first to third sub-organic light-emitting diodes OLEDs1 to OLEDs3. Therefore, the dam layer 111 may include openings that overlap with the first to third sub-organic light-emitting diodes OLEDs1 to OLEDs3, respectively, rather than a single opening that completely overlaps the auxiliary display area SDA. The portion of the dam layer 111 surrounding the emission opening may be a dam portion. Furthermore, the dam layer 111 may overlap the second touch electrode layer 430. For example, the dam portion of the dam layer 111 surrounding the emission opening may overlap with a line of the second touch electrode layer 430, and the width of the line of the second touch electrode layer 430 may be smaller than the width of the dam portion of the dam layer 111. Here, the entire area of the bank layer 111 may be greater than the area of the second touch electrode layer 430 . Therefore, the bank layer 111 may not be completely covered by the second touch electrode layer 430 .

[0148] The lines of the second touch electrode layer 430 may at least partially surround the first opening OP1 and / or the second opening OP2. In an embodiment, for example, the lines of the second touch electrode layer 430 may not be arranged on at least the side surface of the first opening OP1. In other words, at least one of the first openings OP1 may be spatially connected to at least one second opening OP2.

[0149] In the embodiments, for example, reference Figure 11B The second touch electrode layer 430 may define a 1-1st opening OP1-1, a 2-1st opening OP2-1, and a 2-2nd opening OP2-2. The line of the second touch electrode layer 430 may partially surround the 1-1st opening OP1-1, the 2-1st opening OP2-1, and / or the 2-2nd opening OP2-2. In an embodiment, for example, the line of the second touch electrode layer 430 partially surrounding the 1-1st opening OP1-1 may have an incomplete frame shape that is open in one or more directions.

[0150] According to an embodiment, the 2-1st opening OP2-1 may be arranged in the -x direction relative to the 1-1st opening OP1-1. According to an embodiment, the 2-2nd opening OP2-2 may be arranged in the +y direction relative to the 1-1st opening OP1-1. According to an embodiment, the line of the second touch electrode layer 430 may not be arranged between the 1-1st opening OP1-1 and the 2-1st opening OP2-1, and between the 1-1st opening OP1-1 and the 2-2nd opening OP2-2. Therefore, the 1-1st opening OP1-1 and the 2-1st opening OP2-1 may be spatially connected to each other. The 1-1st opening OP1-1 and the 2-2nd opening OP2-2 may also be spatially connected to each other.

[0151] Reference together Figure 7B and Figure 11B , Figure 7B The region in which a portion of the light shielding layer 510 is omitted may be Figure 11B The area between the 1-1 opening OP1-1 and the 2-1 opening OP2-1 in the touch screen overlaps. Accordingly, even when a portion of the light shielding layer 510 is omitted, the second touch electrode layer 430 may not be seen in a plan view.

[0152] refer to Figure 11C The second touch electrode layer 430 may further include a second first opening (hereinafter, referred to as "1-2 opening") OP1-2 at the +x side relative to the 2-2 opening OP2-2 and a third second opening (hereinafter, referred to as "2-3 opening") OP2-3 at the +y side relative to the 1-2 opening OP1-2.

[0153] The line of the second touch electrode layer 430 may not be arranged between the 2-2nd opening OP2-2 and the 1-2nd opening OP1-2. Therefore, the 2-2nd opening OP2-2 and the 1-2nd opening OP1-2 may be spatially connected to each other. Figure 11A In an embodiment, all of the 2-1st opening OP2-1, the 1-1st opening OP1-1, the 2-2nd opening OP2-2, and the 1-2nd opening OP1-2 may be spatially connected to each other. However, some of the lines of the second touch electrode layer 430 may be arranged between the 2-3rd opening OP2-3 and the 1-2nd opening OP1-2. In an embodiment, for example, the 2-3rd opening OP2-3 and the 1-2nd opening OP1-2 may be spatially separated from each other by a bridge portion 430-1 of the second touch electrode layer 430, and the bridge portion 430-1 is arranged between the 2-3rd opening OP2-3 and the 1-2nd opening OP1-2. According to an embodiment, the bridge portion 430-1 of the second touch electrode layer 430 may extend in the x-direction.

[0154] The spacer SPC may be disposed between the first to third sub-organic light emitting diodes OLEDs1, OLEDs2, and OLEDs3. The first to third sub-organic light emitting diodes OLEDs1, OLEDs2, and OLEDs3 may be spaced apart from each other by the spacer SPC. However, the arrangement of the first to third sub-organic light emitting diodes OLEDs1 to OLEDs3 and the spacer SPC is not limited to Figure 11B or Figure 11C The arrangement is shown in the figure and can be variously changed.

In addition, the spatial separation structure of the 1-2 opening OP1-2 and the 2-3 opening OP2-3 may be repeated. The relationship between the 2-3 opening OP2-3 and the first opening OP1 at the +x side relative to it may be substantially the same as the relationship between the 2-1 opening OP2-1 and the 1-1 opening OP1-1. In other words, the 2-3 opening OP2-3 may be spatially connected to the first opening OP1 at the +x side relative to the first opening OP1. In addition, the bridging portion 430-1 of the second touch electrode layer 430 may be repeatedly arranged in multiple quantities, and the second touch electrode layer 430 may be integrally formed as a single, integral, indivisible part throughout the component area CA. Accordingly, even when lines of the second touch electrode layer 430 are omitted in some areas (eg, between the 1-1 opening OP1-1 and the 2-1 opening OP2-1), all lines of the second touch electrode layer 430 in the component area CA may be electrically connected due to the bridge portion 430-1.

[0163] Figure 12A is a plan view of a component area of a display device according to another embodiment. Figure 12B yes Figure 12A An enlarged plan view of a region XIIB of the display device. Figure 12C yes Figure 12A An enlarged plan view of the display device region XIIC.

[0164] Figure 13A is a plan view of a component area of a display device according to another embodiment. Figure 13B yes Figure 13A Specifically, Figure 13B Can be Figure 13A An enlarged plan view of region XIIIB.

[0165] In an embodiment, Figure 13A and Figure 12B As shown in FIG, the light shielding layer is omitted. Figure 13A The embodiment shown in Figure 12A The same as the embodiment shown in FIG5 in which the light shielding layer is omitted.

[0166] In the embodiments, as mentioned above Figure 7A 、 Figure 7B 、 Figure 11A 、 Figure 11B and Figure 11C As described above, when a portion of the light shielding layer 510 is omitted, a portion of the second touch electrode layer 430 may also be omitted to prevent the second touch electrode layer 430 from being seen.

[0167] According to another embodiment, as shown below with reference to Figure 12A 、 Figure 12B 、 Figure 12C 、 Figure 13A and Figure 13B As described above, in some areas where the light shielding layer 510 can be omitted, the second touch electrode layer 430 may not be removed, but rather the width of the second touch electrode layer 430 may be reduced or minimized. Accordingly, even when a portion of the second touch electrode layer 430 is visible due to the omission of a portion of the light shielding layer 510, the visibility can be minimized by its reduced width.

[0168] refer to Figure 12A , a portion of the light shielding layer 510 may be omitted, and a portion of the second touch electrode layer 430 disposed under the light shielding layer 510 may be exposed. As described above, the second touch electrode layer 430 may include metal, and thus, may reflect external light and may become visible to the user.

[0169] refer to Figure 12B , the lines of the second touch electrode layer 430 may have a shape of a complete frame. Therefore, when a portion of the light shielding layer 510 is omitted (for example, a portion of the light shielding layer on the -x side is omitted), some of the lines of the second touch electrode layer 430 may be visible. Here, the width of the lines may be reduced or substantially thin to reduce the visibility of the lines of the second touch electrode layer 430.

[0170] Figure 12C The diagram shows an embodiment in which a portion of the light shielding layer 510 on the -y side can be removed. The lines of the second touch electrode layer 430 in the corresponding area can also have a reduced width or a thin width to reduce visibility. In addition, some of the lines of the second touch electrode layer 430 can be covered by the color filter 520 (e.g., the second color filter 522).

[0171] In an embodiment, as described above, in the case where the widths of some of the lines of the second touch electrode layer 430 are reduced, the widths of the lines of the second touch electrode layer 430 may vary according to the positions of the lines. Figure 13A and Figure 13B Describe such features in detail.

[0172] refer to Figure 13A and Figure 13B , the width of the line of the second touch electrode layer 430 may be variously changed.

[0173] In an embodiment, for example, Figure 13BAs shown in FIG, the second touch electrode layer 430 may include a first portion 431, a second portion 432, a third portion 433, and a fourth portion 434 surrounding the first opening OP1. The second touch electrode layer 430 may include a fifth portion 435 disposed between adjacent second openings OP2. In some embodiments, the width w1 of the first portion 431, the width w2 of the second portion 432, and the width w4 of the fourth portion 434 may be smaller than the width w3 of the third portion 433. In some embodiments, the width w5 of the fifth portion 435 may be smaller than the width w3 of the third portion 433.

[0174] Return Reference Figure 5 Each light-shielding portion of the light-shielding layer 510 disposed on the second touch electrode layer 430 may have a different width. In embodiments, for example, as described above, the width W1 of the first light-shielding portion 511, the width W2 of the second light-shielding portion 512, the width W3 of the third light-shielding portion 513, the width W4 of the fourth light-shielding portion 514, and / or the width W5 of the fifth light-shielding portion 515 may differ from one another. Therefore, the probability of each light-shielding portion being lost during the display device manufacturing process may also differ from one another. In embodiments, for example, the probability of a light-shielding portion being lost during the display device manufacturing process may be increased by reducing the width of the light-shielding portion. Therefore, in the region overlapping with the light-shielding portion of the light-shielding layer 510 with the highest probability of being lost during the display device manufacturing process, it may be desirable to have a structure in which some of the lines of the second touch electrode layer 430 are omitted, or a structure in which the width of some of the lines of the second touch electrode layer 430 is smaller than the width of other lines of the second touch electrode layer 430. In an embodiment, for example, when the width W1 of the first light-shielding portion 511 is smaller than the width W3 of the third light-shielding portion 513, during the manufacturing process of the display device, the probability of loss of the first light-shielding portion 511 may be higher than the probability of loss of the third light-shielding portion 513. Therefore, in the area overlapping with the first light-shielding portion 511, it is desirable to remove one or more of the lines of the second touch electrode layer 430 or reduce their width.

[0175] For example, according to the embodiment, referring to Figure 5 、 Figure 7B and Figure 11B , Figure 5 The width W1 of the first light shielding portion 511 may be smaller than the width W3 of the third light shielding portion 513. Figure 7B An embodiment is illustrated in which the probability of loss of the first light shielding portion 511 may be higher than the probability of loss of the third light shielding portion 513 during the manufacturing process of the display device and the first light shielding portion 511 is lost. Here, Figure 11BThe diagram illustrates an embodiment in which some of the lines of the second touch electrode layer 430 overlapping with the first light shielding portion 511 can be removed so that the lines of the second touch electrode layer 430 disposed under the first light shielding portion 511 can be effectively prevented from becoming visible due to the loss of the first light shielding portion 511.

[0176] According to the embodiment, refer to Figure 5 、 Figure 12B and Figure 13B , Figure 5 The width W1 of the first light shielding portion 511 may be smaller than the width W3 of the third light shielding portion 513. Figure 12B The diagram illustrates an embodiment in which the probability of loss of the first light-shielding portion 511 is higher than the probability of loss of the third light-shielding portion 513 during the manufacturing process of the display device, and the first light-shielding portion 511 is lost. To reduce the visibility of the lines of the second touch electrode layer 430 beneath the first light-shielding portion 511 due to the loss of the first light-shielding portion 511, the width w1 of the first portion 431 of the second touch electrode layer 430 can be formed to be smaller than the width w3 of the third portion 433. The increase in resistance of the lines of the second touch electrode layer 430 that may occur when the width w1 of the first portion 431 is reduced can be mitigated or compensated by increasing the width w3 of the third portion 433. In such an embodiment, it is desirable that the width w3 of the third portion 433 of the second touch electrode layer 430 be smaller than the width W3 of the third light-shielding portion 513 so that the third portion 433 can be covered by the light-shielding layer 510.

[0177] Embodiments may have a structure in which some of the lines of the second touch electrode layer 430 are omitted, a structure in which the widths of the lines of the second touch electrode layer 430 may be different from each other, or a combination thereof.
