[0004] As multimedia has developed, the importance of display devices has increased. Therefore, various types of display devices, such as a liquid crystal display (LCD) and an organic light emitting display (OLED), have been used.

[0005] Among these display devices, an organic light emitting display device displays images by using an organic light emitting element that generates light through recombination of electrons and holes. The organic light emitting display device has advantages in that it has a fast response speed, high brightness and a wide viewing angle, and is driven with low power consumption.

[0006] Since the performance of an organic light-emitting display device is deteriorated by the presence of external moisture or oxygen, the organic light-emitting element is generally encapsulated to protect it from the external moisture or oxygen. Recently, in order to make the organic light-emitting display device thin and / or flexible, a thin film encapsulation (TFE) composed of multiple layers including an inorganic film and multiple inorganic films or organic films has been used as a means for encapsulating the organic light-emitting element.

[0007] Recently, an organic light emitting display device has an image display function and includes a touch sensing electrode for receiving a user's touch. Therefore, through the touch sensing electrode, it is easier for a user to use the organic light emitting display device.

[0035] For the purpose of explanation, in the following description, many specific details are set forth to provide a thorough understanding of various exemplary embodiments of the present invention. As used herein, "embodiment" is a non-limiting example of a device or method using one or more inventive concepts in the inventive concepts disclosed herein. However, it is apparent that various exemplary embodiments can be practiced without these specific details or using one or more equivalent arrangements. In other examples, well-known structures and devices are shown in block diagram form to avoid making various exemplary embodiments unnecessarily ambiguous. In addition, various exemplary embodiments may be different, but need not be exclusive. For example, without departing from the inventive concept, the specific shape, configuration and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0036] Unless otherwise specified, the exemplary embodiments shown should be understood as providing exemplary features of different details of some ways in which the inventive concept can be implemented in practice. Therefore, unless otherwise specified, the features, components, modules, layers, films, panels, regions and / or aspects, etc. (hereinafter, individually or collectively referred to as elements) of various embodiments may be combined, separated, interchanged and / or rearranged in other ways without departing from the inventive concept.

[0037] The use of cross hatching and / or shading in the drawings is generally provided to make the boundaries between adjacent elements clear. Therefore, unless specified, the presence or absence of cross hatching or shading does not express or indicate any preference or requirement for a specific material, material property, size, ratio, commonality between the elements shown and / or any other characteristics, attributes, properties, etc. of the elements. In addition, in the drawings, the size and relative size of the elements may be exaggerated for the purpose of clarity and / or description. When the exemplary embodiments can be implemented differently, a specific process sequence can be performed differently from the described sequence. For example, two processes described in succession can be performed substantially simultaneously or in an order opposite to the described sequence. In addition, the same reference numerals refer to the same elements.

[0038] When an element or layer is referred to as being "on", "connected to" or "coupled to" another element or layer, it may be directly on, directly connected to or directly coupled to the other element or layer, or there may be an intervening element or layer. However, when an element or layer is referred to as being directly "on", "directly connected to" or "directly coupled to" another element or layer, there is no intervening element or layer. For this reason, the term "connection" may refer to a physical connection, electrical connection and / or fluid connection with or without an intervening element. In addition, the dr1 axis, the dr2 axis and the dr3 axis are not limited to the three axes of a rectangular coordinate system (such as the x-axis, the y-axis and the z-axis), and may be interpreted in a broader sense. For example, the dr1 axis, the dr2 axis and the dr3 axis may be perpendicular to each other, or may represent different directions that are not perpendicular to each other. For the purpose of this disclosure, "at least one of X, Y, and Z" and "at least one selected from the group consisting of X, Y, and Z" may be interpreted as only X, only Y, only Z, or any combination of two or more of X, Y, and Z, such as XYZ, XYY, YZ, and ZZ. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0039] Although the terms "first", "second", etc. may be used herein to describe various types of elements, these elements should not be limited by these terms. These terms are used to distinguish one element from another element. Therefore, without departing from the teachings of the present disclosure, the first element discussed below may be referred to as the second element.

[0040] For descriptive purposes, spatially relative terms such as "beneath," "below," "under," "lower," "above," "upper," "over," "higher," "side" (e.g., when in a "sidewall"), and the like may be used herein and thereby describe the relationship of one element to another element(s) as shown in the accompanying drawings. Spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is flipped, elements described as being "below" or "beneath" other elements or features would be oriented "above" the other elements or features. Thus, the exemplary term "below" may encompass both an orientation above and an orientation below. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or in other orientations), and therefore, the spatially relative descriptors used herein are interpreted accordingly.

[0041] The terms used herein are for the purpose of describing specific embodiments, but are not intended to be limiting. Unless the context clearly indicates otherwise, as used herein, the singular forms "a", "an" and "the" are intended to also include plural forms. In addition, when used in this specification, the terms "comprise", "comprising", "include" and / or "including" specify the existence of the features, wholes, steps, operations, elements, components and / or groups thereof described, but do not exclude the existence or addition of one or more other features, wholes, steps, operations, elements, components and / or groups thereof. It should also be noted that, as used herein, the terms "substantially", "about" and other similar terms are used as approximate terms rather than as degree terms, and therefore, are used to allow for the inherent deviations of the measured values, calculated values ​​and / or provided values ​​that will be recognized by those of ordinary skill in the art.

[0042] The exemplary embodiments are described herein with reference to cross-sectional views and / or exploded views as schematic diagrams of idealized exemplary embodiments and / or intermediate structures. Thus, variations in the shapes of the illustrations caused by, for example, manufacturing techniques and / or tolerances should be expected. Therefore, the exemplary embodiments disclosed herein should not necessarily be interpreted as being limited to the particular shapes shown of the regions, but should include shape deviations caused by, for example, manufacturing. To this end, the regions shown in the drawings may be schematic in nature, and the shapes of these regions may not reflect the actual shapes of the regions of the device, and therefore, are not necessarily intended to be limiting.

[0043] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as those commonly understood by those skilled in the art to which the present disclosure belongs. 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 should not be interpreted in an idealized or overly formal sense, unless explicitly defined as such herein.

[0044] The display device conceived according to the present invention is a device for displaying moving images or still images, or a device for displaying stereoscopic images, and can be used as a display screen for various products (such as televisions, laptops, monitors, billboards and the Internet of Things, as well as portable electronic products such as mobile communication terminals, smart phones, tablet computers, smart watches and navigation devices).

[0045] Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. In the accompanying drawings, the same or similar reference numerals are used for the same components.

[0046] Figure 1is a plan view of an organic light emitting display device according to an exemplary embodiment of the present invention. Figure 2 is a perspective view of an organic light emitting display device according to an exemplary embodiment of the present invention. Figure 3 is a schematic cross-sectional view of an organic light emitting display device according to an exemplary embodiment of the present invention.

[0047] refer to Figure 1 and Figure 2 , the organic light emitting display device 1 may have a foldable characteristic.

[0048] The organic light-emitting display device 1 may have a rectangular shape, and when the organic light-emitting display device 1 is unfolded, the length in the first direction dr1 is greater than the length in the second direction dr2. In other words, the edge of the organic light-emitting display device 1 may include a long side extending in the first direction dr1 and a short side extending in the second direction dr2. The edge of the organic light-emitting display device 1 may include a curved corner located between adjacent long sides and short sides. However, it should be understood that the inventive concept is not limited to the above directions, and the first direction dr1 and the second direction dr2 refer to opposite directions that intersect each other.

[0049] The organic light emitting display apparatus 1 may include a display area DA and a non-display area NDA.

[0050] The display area DA is defined as an area for displaying an image. The organic light emitting display device 1 may include a plurality of pixels located in the display area DA. The display area DA may be used not only as an area for displaying an image but also as an area for recognizing a user's touch input or fingerprint.

[0051] The non-display area NDA is defined as an area where no image is displayed. The non-display area NDA may be arranged outside the display area DA. The non-display area NDA may be provided to surround the display area DA. In an exemplary embodiment, the non-display area NDA may be an annular area having an outer edge and an inner edge, wherein the outer edge and the inner edge each have a rectangular shape with rounded corners, but the shape of the non-display area NDA is not limited thereto.

[0052] A speaker module, a camera module, a sensor module, etc. may be disposed in a portion of the non-display area NDA. In an exemplary embodiment, the sensor module may include at least one of a brightness sensor, a proximity sensor, an infrared sensor, and an ultrasonic sensor. The arrangement of the speaker module, the camera module, and the sensor module is not limited to the above arrangement.

[0053] The organic light-emitting display device 1 can be bent and unfolded. The organic light-emitting display device 1 may include a bending area BA and a first non-bending area NBA1 and a second non-bending area NBA2, wherein the bending area BA is bent based on a bending axis; and the first non-bending area NBA1 and the second non-bending area NBA2 are not bent on either side of the bending axis. In an exemplary embodiment, the organic light-emitting display device 1 may be folded inwardly so that the display area DA is bent inwardly. However, the inventive concept is not limited thereto. In another exemplary embodiment, the organic light-emitting display device 1 may be folded outwardly so that the display area DA is bent outwardly.

[0054] refer to Figure 3 In an exemplary embodiment, the organic light-emitting display device 1 may include a first substrate 10, a circuit layer 20 disposed on the first substrate 10, a light-emitting element layer 30 disposed on the circuit layer 20, an encapsulation layer 40 disposed on the light-emitting element layer 30, a touch layer 50 disposed on the encapsulation layer 40, an anti-reflection layer 60 disposed on the touch layer 50, and a second substrate 70 disposed on the anti-reflection layer 60. However, the inventive concept is not limited thereto. Each layer may have a single-layer or multi-layer structure, and if necessary, each layer may be provided with an additional layer or a portion thereof may be omitted. The stacked structure of the organic light-emitting display device 1 will be described in detail later.

[0055] The touch layer 50 may include a touch sensing unit 50a (see Figure 4 ). First, refer to Figure 4 The arrangement structure of components constituting the touch layer 50 is described.

[0056] Figure 4 is a plan view schematically showing a layout structure of a touch sensing unit.

[0057] refer to Figure 4 The touch sensing unit 50a includes a plurality of first sensing electrodes IE1, a plurality of second sensing electrodes IE2, a signal wiring unit, and a pad terminal unit TPA.

[0058] The organic light emitting display device 1 includes a base layer provided with a touch sensing unit 50a. For example, the base layer may correspond to the second inorganic film 453 of the encapsulation layer 450 (see Figure 6 ), but the inventive concept is not limited thereto. The display area DA and the non-display area NDA may be defined in the base layer. The bending area BA, the first non-bending area NBA1 and the second non-bending area NBA2 may also be defined in the base layer.

[0059] The signal wiring unit may include a plurality of signal wirings RX and TX. One end of each of the plurality of signal wirings RX and TXd is directly connected to the first sensing electrode IE1 or the second sensing electrode IE2, and the other ends of the plurality of signal wirings RX and TXd are directly connected to the pad terminal unit TPA to electrically connect the first sensing electrode IE1 and the second sensing electrode IE2 to the pad terminal unit TPA. The signal wiring unit may be disposed to surround the outside of the first sensing electrode IE1 and the second sensing electrode IE2. For ease of explanation, the space of the region in which the signal wiring unit is disposed is exaggerated in the drawings.

[0060] The plurality of first sensing electrodes IE1 and the plurality of second sensing electrodes IE2 may overlap with the display area DA and may not overlap with the non-display area NDA. The signal wiring unit and the pad terminal unit TPA may overlap with the non-display area NDA and may not overlap with the display area DA. In this specification, unless otherwise specified, the expression "overlap" means that two components overlap each other in the thickness direction of the organic light-emitting display device 1 (for example, perpendicular to the base substrate 101 (see Figure 6 )'s surface direction, that is, the third direction dr3) in the accompanying drawing.

[0061] The first sensing electrode IE1 and the second sensing electrode IE2 may each include a plurality of mesh patterns.

[0062] In the present exemplary embodiment, a case where the first sensing electrode IE1 is a driving electrode and the second sensing electrode IE2 is a sensing electrode will be described as an example. In another exemplary embodiment, the first sensing electrode IE1 may be a sensing electrode, and the second sensing electrode IE2 may be a driving electrode.

[0063] The drawings show that the first sensing electrode IE1 includes first to fourth driving electrodes spaced apart in the second direction dr2, and the second sensing electrode IE2 includes first to fifth sensing electrodes spaced apart in the first direction dr1. In addition, the drawings show that each of the driving electrodes includes six grid patterns arranged in the first direction dr1, and each of the sensing electrodes includes five grid patterns arranged in the second direction dr2. However, the number of the first sensing electrodes IE1 and the second sensing electrodes IE2 and the number of grid patterns included in each of the first sensing electrodes IE1 and the second sensing electrodes IE2 are not limited to the number exemplified above.

[0064] The plurality of first sensing electrodes IE1 and the plurality of second sensing electrodes IE2 may include but are not limited to silver, aluminum, copper, chromium, nickel, titanium, through which a low temperature process is possible. Even if the sensing electrodes IE1 and IE2 are formed by a continuous process, damage to the organic light emitting diode can be prevented.

[0065] Although the drawings illustrate that the pad terminal unit TPA is disposed at the lower side of the organic light-emitting display device 1 and includes a plurality of pad terminals spaced apart in the second direction dr2 , the position of the pad terminal unit TPA and the arrangement of the pad terminals are not limited.

[0066] The signal wiring unit includes a plurality of touch driving wirings TX for connecting each driving electrode and the pad terminal unit TPA and a plurality of touch sensing wirings RX for connecting each sensing electrode and the pad terminal unit TPA.

[0067] In an exemplary embodiment, each driving electrode may be connected to a plurality of touch driving wirings TX1_1 to TX4_1 and TX1_2 to TX4_2. In other words, each driving electrode may be dual-path. The touch driving wirings TX1_2 to TX4_2 connected to the upper side of each of the driving electrodes may be arranged to bypass the respective sensing electrodes IE1 and IE2 along one side.

[0068] Each of the touch sensing wirings RX1 to RX5 may be connected to one sensing electrode. In other words, each of the sensing electrodes may be single-path. The touch sensing wirings RX1 to RX5 may be disposed to bypass the corresponding sensing electrodes IE1 and IE2 along the other side edge.

[0069] The voltage level of the driving voltage signal provided to each driving electrode may be higher than the voltage level of the sensing voltage signal provided to each sensing electrode. Since a signal with a relatively high voltage level is provided to each driving electrode, the voltage level in the sensing electrode may be greatly changed for each position according to the distance from the wiring. For example, when one of the touch driving wirings TX1_1 to TX4_1 is connected to only one side end of each driving electrode, the voltage level of the grid pattern adjacent to the one side end may be greatly different from the voltage level of the grid pattern adjacent to the other side end. A plurality of touch driving wirings TX1_1 to TX4_1 and TX1_2 to TX4_2 are connected to each driving electrode, and therefore, the voltage level difference between the grid patterns set adjacent to both ends of each driving electrode can be minimized. However, the number and arrangement of the touch driving wirings TX1_1 to TX4_1 and TX1_2 to TX4_2 and the touch sensing wirings RX1 to RX5 are not limited to the number and arrangement shown in the accompanying drawings.

[0070] Next, we will refer to Figures 4 to 8 as well as Figure 3 The arrangement relationship of the touch sensing unit 50 a and each component of the organic light emitting display device 1 is described.

[0071] Figure 5 yes Figure 4 An enlarged view of a portion of FF1. Figure 6 is along Figure 5 1 is a cross-sectional view of a portion of the organic light emitting display device taken along line I1 - I1 ′. Figure 7 yes Figure 6 An enlarged view of a portion of FF3. Figure 8 yes Figure 4 An enlarged view of a portion of FF2. Fig. 9 is along Figure 8 1 is a cross-sectional view of a portion of the organic light emitting display device taken along line I2 - I2 ′.

[0072] refer to Figure 4 as well as Figure 5 , the organic light-emitting display device 1 includes light-emitting regions PXA_R, PXA_G, and PXA_B, and non-light-emitting regions surrounding the outer sides of the corresponding light-emitting regions PXA_R, PXA_G, and PXA_B and dividing the corresponding light-emitting regions PXA_R, PXA_G, and PXA_B. The light-emitting regions PXA_R, PXA_G, and PXA_B may be divided by the pixel defining layer PDL. In other words, a portion overlapping with the pixel defining layer PDL in the display area DA may be a non-light-emitting region, and a portion not overlapping with the pixel defining layer PDL may be a light-emitting region PXA_R, PXA_G, or PXA_B. In an exemplary embodiment, the non-light-emitting region may be formed in a grid shape, but its shape is not limited thereto.

[0073] The mesh pattern of each of the sensing electrodes IE1 and IE2 may define a plurality of mesh holes. The mesh holes may correspond one-to-one to the light emitting regions PXA_R, PXA_G, and PXA_B. The mesh pattern may be included in the non-light emitting region.

[0074] The light emitting regions PXA_R, PXA_G, and PXA_B may be divided into a plurality of groups according to the color of light generated in the organic light emitting diodes. Figure 5 The light emitting areas PXA_R, PXA_G, and PXA_B divided into three groups according to the color of light are shown.

[0075] The light emitting regions PXA_R, PXA_G and PXA_B may be configured according to the light emitting layer ( Figure 6312) have different areas from each other according to the color of the light emitted by the organic light emitting diode. The areas of the light emitting regions PXA_R, PXA_G, and PXA_B may be determined according to the type of the organic light emitting diode. For example, the light emitting regions PXA_R, PXA_G, and PXA_B may include a first light emitting region PXA_R, a second light emitting region PXA_G, and a third light emitting region PXA_B. The light emitting regions PXA_R, PXA_G, and PXA_B may be formed to have a larger area in the order of the second light emitting region PXA_G, the first light emitting region PXA_R, and the third light emitting region PXA_B. In the present exemplary embodiment, although the first light emitting region PXA_R is a light emitting region emitting red light, the second light emitting region PXA_G is a light emitting region emitting green light, and the third light emitting region PXA_B is a light emitting region emitting blue light, the inventive concept is not limited thereto. In another exemplary embodiment, the first light emitting region PXA_R, the second light emitting region PXA_G, and the third light emitting region PXA_B may be light emitting regions that emit cyan, magenta, and yellow light but do not emit red, green, and blue light.

[0076] The mesh holes may be divided into a plurality of groups having different areas from each other. The mesh holes may be divided into three groups according to the corresponding light emitting areas PXA_R, PXA_G, and PXA_B.

[0077] However, it is shown that the mesh holes correspond to the light-emitting regions PXA_R, PXA_G, and PXA_B one by one, but the inventive concept is not limited thereto. Each mesh hole may correspond to two or more light-emitting regions PXA_R, PXA_G, and PXA_B. It is shown that the areas of the light-emitting regions PXA_R, PXA_G, and PXA_B are different, but the inventive concept is not limited thereto. The sizes of the light-emitting regions PXA_R, PXA_G, and PXA_B may be equal to each other, and the sizes of the mesh holes may also be equal to each other.

[0078] The plane shape of the mesh hole is not limited and may have a polygonal shape other than a rhombus. The plane shape of the mesh hole may have a polygonal shape with rounded corners.

[0079] Since the plurality of first sensing electrodes IE1 and the plurality of second sensing electrodes IE2 have a mesh shape, the plurality of first sensing electrodes IE1 and the plurality of second sensing electrodes IE2 do not overlap with the light emitting regions PXA_R, PXA_G, and PXA_B, so that the plurality of first sensing electrodes IE1 and the plurality of second sensing electrodes IE2 may not be observed by a user of the organic light emitting display device 1. In addition, parasitic capacitance between the first sensing electrodes IE1 and the plurality of second sensing electrodes IE2 with respect to corresponding electrodes of the light emitting element layer 30 may be reduced.

[0080] In the following, reference will be made to Figure 6The stacking relationship of the organic light emitting display device 1 is described in more detail.

[0081] The base substrate 101 may be a rigid substrate or a flexible substrate. Here, when the base substrate 101 is a rigid substrate, the base substrate 101 may be a glass substrate, a quartz substrate, a glass ceramic substrate, or a crystal glass substrate. When the base substrate 101 is a flexible substrate, the base substrate 101 may be one of a plastic substrate and a thin film substrate including a polymer organic material.

[0082] The base substrate 101 may be provided with the above-mentioned display area DA and non-display area NDA.

[0083] Figure 6 The base substrate 101 shown in FIG. 1 may correspond to Figure 3 The first substrate 10 is provided.

[0084] A buffer layer 201 is disposed on the base substrate 101. The buffer layer 201 is used to smooth the surface of the base substrate 101 and prevent the penetration of moisture or external air. The buffer layer 201 may be an inorganic film. The buffer layer 201 may be a single-layer film or a multi-layer film.

[0085] A plurality of thin film transistors TR1, TR2, and TR3 are disposed on the buffer layer 201. Here, the plurality of thin film transistors TR1, TR2, and TR3 may be driving thin film transistors.

[0086] The plurality of thin film transistors TR1, TR2, and TR3 may include a first thin film transistor TR1, a second thin film transistor TR2, and a third thin film transistor TR3. At least one of the thin film transistors TR1, TR2, and TR3 may be provided for each pixel. For example, the first thin film transistor TR1 may be disposed in the first light emitting region PXA_R, the second thin film transistor TR2 may be disposed in the second light emitting region PXA_G, and the third thin film transistor TR3 may be disposed in the third light emitting region PXA_B.

[0087] The thin film transistors TR1, TR2 and TR3 may include semiconductor layers A1, A2 and A3, gate electrodes G1, G2 and G3, source electrodes S1, S2 and S3, and drain electrodes D1, D2 and D3, respectively. More specifically, each of the semiconductor layers A1, A2 and A3 is disposed on the buffer layer 201. Each of the semiconductor layers A1, A2 and A3 may include amorphous silicon, polycrystalline silicon, low temperature polycrystalline silicon and an organic semiconductor. In another exemplary embodiment, each of the semiconductor layers A1, A2 and A3 may include an oxide semiconductor.

[0105] The first pixel electrode 311, the organic light emitting layer 312 and the second pixel electrode 313 may constitute an organic light emitting diode (OLED). Figure 6 The first pixel electrode 311 to the second pixel electrode 313 shown in FIG. Figure 3 The light emitting element layer 30 is formed.

[0106] The second pixel electrode 313 may be provided with an encapsulation layer 450. The encapsulation layer 450 includes an inorganic film and an organic film. The encapsulation layer 450 may include a plurality of stacked films. As shown in the drawings, the encapsulation layer 450 may be formed of a multilayer film including a first inorganic film 451, an organic film 452, and a second inorganic film 453 stacked in sequence. Here, the first inorganic film 451 and the second inorganic film 453 may include a silicon oxide (SiO x ), silicon nitride (SiN x ) and silicon oxynitride (SiON x ), and the organic film 452 may include any one selected from the group consisting of epoxy resin, acrylate and urethane acrylate.

[0107] Figure 6 The encapsulation layer 450 shown in FIG. 4 may correspond to Figure 3 The encapsulation layer 40 is provided.

[0108] The touch sensing unit 50a may be sequentially disposed on the encapsulation layer 450. The touch sensing unit 50a may be sequentially disposed on the encapsulation layer 450 in the order of the first touch conductive layer, the touch insulating layer 511, and the second touch conductive layer. Figure 7 and Figure 8 The stacked structure of the touch sensing unit 50 a is described.

[0109] refer to Figures 3 to 5 , Figure 7 and Figure 8 The first sensing electrode IE1 and the second sensing electrode IE2 are arranged to cross each other. The first sensing electrode IE1 and the second sensing electrode IE2 may be insulated from each other at the intersection of the first sensing electrode IE1 and the second sensing electrode IE2, and the touch insulating layer 511 is located between the first sensing electrode IE1 and the second sensing electrode IE2.

[0110] The mesh pattern of any one of the first sensing electrode IE1 and the second sensing electrode IE2 may be electrically connected through the bridge wiring BE. In the drawings, the case where the mesh pattern of the first sensing electrode IE1 is physically connected and the mesh pattern of the second sensing electrode IE2 is electrically connected through the bridge wiring BE is described as an example, but the inventive concept is not limited thereto. In another exemplary embodiment, the mesh pattern of the first sensing electrode IE1 may be electrically connected through the bridge wiring BE, and the mesh pattern of the second sensing electrode IE2 may be physically connected.

[0111] The bridge wiring BE may be arranged in a region overlapping the pixel defining layer PDL.

[0112] The first touch conductive layer may be disposed on the second inorganic film 453 of the encapsulation layer 450. In an exemplary embodiment, a second buffer layer 501 may be disposed between the encapsulation layer 450 and the first touch conductive layer. In other words, the second buffer layer 501 may be disposed on the second inorganic film 453, and the second buffer layer 501 may be used to smooth the surface of the encapsulation layer 450 and prevent the penetration of moisture or external air. In other words, the upper surface of the second buffer layer 501 may be a flat surface. The second buffer layer 501 may be a silicon nitride (SiN x ). The second buffer layer 501 may be a single-layer film or a multi-layer film. In another exemplary embodiment, the second buffer layer 501 may be omitted, and in this case, the first touch conductive layer may be directly disposed on the second inorganic film 453 of the encapsulation layer 450.

[0113] The thickness of the second buffer layer 501 may be about to about

[0114] The first touch conductive layer may include at least one metal selected from molybdenum (Mo), aluminum (Al), platinum (Pt), palladium (Pd), silver (Ag), magnesium (Mg), gold (Au), nickel (Ni), neodymium (Nd), iridium (Ir), chromium (Cr), calcium (Ca), titanium (Ti), tantalum (Ta), tungsten (W) and copper (Cu). For example, the first touch conductive layer may have a three-layer structure of titanium (Ti) / aluminum (Al) / titanium (Ti).

[0115] The first touch conductive layer may include the bridge wiring BE and the signal wiring unit described above. In other words, the bridge wiring BE and the signal wiring unit may be provided on the same layer and may include the same material.

[0116] The touch insulating layer 511 is disposed on the first touch conductive layer. The touch insulating layer 511 may include at least one contact hole exposing a portion of the bridge wiring BE and the signal wiring unit.

[0117] In an exemplary embodiment, the touch insulating layer 511 may be disposed on the entire surface of the substrate, but the present inventive concept is not limited thereto. The touch insulating layer 511 may include an organic material or an inorganic material. In this case, examples of the inorganic material may include silicon oxide (SiO x ), silicon nitride (SiN x ), silicon oxynitride, aluminum oxide, tantalum oxide, hafnium oxide, zirconium oxide, and titanium oxide. Examples of organic materials may include imide-based polymers, general polymers such as polymethyl methacrylate (PMMA) and polystyrene (PS), polymer derivatives having a phenol group, acrylic polymers, aryl ether-based polymers, amide-based polymers, fluorine-based polymers, paraxylene-based polymers, vinyl alcohol-based polymers, and mixtures thereof. They may be used alone or in combination with each other. The touch insulating layer 511 may be a single-layer film or a multilayer film consisting of stacked films of different materials.

[0118] The thickness of the touch insulating layer 511 may be about to When the touch insulation layer 511 includes an inorganic material, the refractive index thereof may be about 1.93, and when the touch insulation layer 511 includes an organic material, the refractive index thereof may be about 1.53.

[0119] refer to Figures 4 to 9 , the touch insulating layer 511 includes a flat area FA and a lens area RA, the flat area FA has a flat upper surface at a first height H1 from a reference line, and the lens area RA has a curved upper surface at a second height H2 from the reference line, and the second height H2 is different from the first height H1. The reference line may be an imaginary line based on the flat upper surface of the buffer layer 201 or the second buffer layer 501. The first height H1 of the flat area FA may be constant for each position, and the second height H2 of the lens area RA may be changed for each position instead of being constant. The upper surface of the touch insulating layer 511 in the lens area RA may be concave or convex. In the present exemplary embodiment, the case where the upper surface of the touch insulating layer 511 is concave will be described as an example.

[0120] The flat area FA may mainly overlap the pixel defining layer PDL. Therefore, the bridge wiring BE may be disposed under the flat area FA.

[0121] The lens area RA may mainly overlap a portion of the first pixel electrode 311 exposed by the first openings L1_1, L1_2, and L1_3 of the pixel defining layer PDL. A boundary between the flat area FA and the lens area RA may be formed at a portion overlapping the pixel defining layer PDL and the first pixel electrode 311, or at a portion overlapping the first openings L1_1, L1_2, and L1_3.

[0122] In an exemplary embodiment, the width of the lens area RA may be substantially the same as the width of each of the first openings L1_1 , L1_2 , and L1_3 , but the inventive concept is not limited thereto.

[0123] The second height H2 may be smaller than the first height H1. The second height H2 may be configured to generally become lower from the boundary between the flat area FA and the lens area RA toward the inside of the lens area RA, but the inventive concept is not limited thereto. The second height H2 may be lowest at the center of the lens area RA. In another exemplary embodiment, the second height H2 may include a specific area maintaining the same thickness even if the distance from the boundary between the flat area FA and the lens area RA is different.

[0124] The second height H2 may be configured such that a change in slope may generally decrease from the boundary between the flat area FA and the lens area RA toward the inside of the lens area RA. In other words, a second-order derivative value of the second height H2 with respect to the distance from the boundary between the flat area FA and the lens area RA may be generally negative, but the inventive concept is not limited thereto. In another exemplary embodiment, in a portion of the lens area RA, a second-order derivative value of the second height H2 with respect to the distance may be 0 or positive. In this case, the shape of the lens area RA may be a trapezoidal shape in which the lower side is shorter than the upper side.

[0125] The cross section of the lens area RA may have a substantially concave lens shape. In other words, the cross section of the lens area RA may be a shape in which the thickness becomes thinner toward the center of the lens area RA. The lens area RA may function as a concave lens. When light emitted from the organic light emitting layer 312 passes through the lens area RA, the light may be relatively diffused.

[0126] Further, when a denser material is disposed on the upper layer of the lens region RA, light emitted from the organic light emitting layer 312 has a converging effect, and thus, front light efficiency can be increased. Therefore, light captured by the interface of the encapsulation layer 450 can be extracted, thereby increasing the total amount of light.

[0127] The lens area RA may have a relatively steep inclination at a boundary with the flat area FA, and may be gradually thinner toward a central portion of the lens area RA to have a relatively gentle inclination at the central portion thereof. In an exemplary embodiment, in the lens area RA, a slope of a boundary between the lens area RA and the flat area FA (a tangent value of an acute angle between a tangent line and a flat upper surface of the buffer layer 201 or the second buffer layer 501, the acute angle hereinafter referred to as a taper angle (θ)) may be tan50° to tan80°.

[0128] The cone angle (θ) can be adjusted to increase light efficiency. As the cone angle (θ) decreases, the front light efficiency can increase.

[0129] The lens area RA may be formed to have a circular pattern on a plane, but the inventive concept is not limited thereto. When the lens area RA is formed to have a circular pattern on a plane, a light converging effect may be enhanced regardless of the direction of light emitted from the organic light emitting layer 312 .

[0130] The second touch conductive layer is disposed on the touch insulating layer 511. In an exemplary embodiment, the second touch conductive layer may be disposed on the flat area FA of the touch insulating layer 511. The second touch conductive layer may include second openings L2_1, L2_2, and L2_3 for exposing a portion of the touch insulating layer 511. The second openings L2_1, L2_2, and L2_3 may include the entire lens area RA of the touch insulating layer 511 and a portion of the flat area FA adjacent to the lens area RA.

[0131] The second openings L2_1, L2_2, and L2_3 may include portions overlapping the first openings L1_1, L1_2, and L1_3. In an exemplary embodiment, the widths of the second openings L2_1, L2_2, and L2_3 may be greater than the widths of the first openings L1_1, L1_2, and L1_3. Therefore, an ideal viewing angle and brightness ratio of the organic light emitting display device 1 may be ensured.

[0132] The second touch conductive layer may include at least one metal selected from molybdenum (Mo), aluminum (Al), platinum (Pt), palladium (Pd), silver (Ag), magnesium (Mg), gold (Au), nickel (Ni), neodymium (Nd), iridium (Ir), chromium (Cr), calcium (Ca), titanium (Ti), tantalum (Ta), tungsten (W), and copper (Cu). The second touch conductive layer may be made of the same material as the first touch conductive layer, and for example, the second touch conductive layer may have a three-layer structure of titanium (Ti) / aluminum (Al) / titanium (Ti).

[0133] The second touch conductive layer may include the plurality of first sensing electrodes IE1 and the plurality of second sensing electrodes IE2 that have been described above. In other words, the mesh patterns of the sensing electrodes IE1 and IE2 may all be disposed on the same layer and may include the same material.

[0134] Some of the components of the second touch conductive layer may directly contact the first touch conductive layer through the contact holes of the touch insulating layer 511. For example, the mesh pattern of the second sensing electrodes IE2 may be connected to the bridge wiring BE, and the first sensing electrodes IE1 and the second sensing electrodes IE2 may be connected to corresponding signal wirings RX and TX.

[0135] The first sensing electrode IE1 and the second sensing electrode IE2 may be disposed to overlap with the pixel defining layer PDL. In an exemplary embodiment, the mesh patterns of the sensing electrodes IE1 and IE2 may be arranged to overlap with each other in a region where the pixel defining layer PDL is disposed. In other words, the width of the mesh pattern of each of the sensing electrodes IE1 and IE2 may be smaller than the width of the pixel defining layer PDL.

[0136] The black matrix BM and the liquid-repellent material layer LR may be sequentially stacked on the second touch conductive layer to overlap the second touch conductive layer.

[0137] The black matrix BM may be directly disposed on the grid pattern of each of the sensing electrodes IE1 and IE2. The black matrix BM includes a material capable of blocking light. For example, the black matrix BM may include an organic material having a high light absorbance. The black matrix BM may include a black pigment or a black dye. The black matrix BM includes a photosensitive organic material and may include, for example, a colorant such as a pigment or a dye. The black matrix BM may have a single-layer structure or a multi-layer structure.

[0138] In an exemplary embodiment, the thickness of the black matrix BM may be about 2 μm to about 4 μm, but is not limited thereto.

[0139] The liquid repellent material layer LR may be directly disposed on the black matrix BM. The liquid repellent material layer LR may include an oriented material having liquid repellency relative to the color filters CF_R, CF_G, and CF_B solutions to be described later. The oriented material may be an organic polymer material. For example, the organic polymer material may include at least one of a fluorinated acrylic monomer, a fluorinated alkyl organic material, and a hydrophobic fluorinated silane accelerator.

[0140] In an exemplary embodiment, the thickness of the liquid-repellent material layer LR may be thinner than the thickness of the black matrix BM, but the present invention is not limited thereto.

[0141] The grid pattern, the black matrix BM, and the liquid repellent material layer LR stacked in sequence may form a dam. The dam may form a plurality of second openings L2_1, L2_2, and L2_3 exposing the touch insulating layer 511. The grid pattern, the black matrix BM, and the liquid repellent material layer LR of each of the sensing electrodes IE1 and IE2 are stacked in sequence, thereby reducing the number of masks when manufacturing the organic light-emitting display device 1.

[0142] Color filters CF_R, CF_G, and CF_B may be disposed on the touch insulation layer 511. The color filters CF_R, CF_G, and CF_B may be disposed in the second openings L2_1, L2_2, and L2_3 formed by the dam.

[0143] The color filters CF_R, CF_G, and CF_B may include a first color filter CF_R, a second color filter CF_G, and a third color filter CF_B. The first color filter CF_R may be disposed in the first light emitting region PXA_R, the second color filter CF_G may be disposed in the second light emitting region PXA_G, and the third color filter CF_B may be disposed in the third light emitting region PXA_B. In an exemplary embodiment, the first color filter CF_R may be a red color filter, the second color filter CF_G may be a green color filter, and the third color filter CF_B may be a blue color filter. In other words, the first light emitting region PXA_R of red color may include an organic light emitting layer 312 of red color and a first color filter CF_R of red color, the second light emitting region PXA_G of green color may include an organic light emitting layer 312 of green color and a second color filter CF_G of green color, and the third light emitting region PXA_B of blue color may include an organic light emitting layer 312 of blue color and a third color filter CF_B of blue color. In another exemplary embodiment, the first, second, and third emission regions PXA_R, PXA_G, and PXA_B may include a white organic light emitting layer and color filters CF_R, CF_G, and CF_B of corresponding colors, respectively. The white organic light emitting layer may be formed by stacking two or more organic light emitting layers.

[0144] The first color filter CF_R selectively transmits red light. Here, the wavelength of the red light may be about 620nm to about 750nm. The second color filter CF_G selectively transmits green light. Here, the wavelength of the green light may be about 495nm to about 570nm. The third color filter CF_B selectively transmits blue light. Here, the wavelength of the blue light may be about 450nm to about 495nm.

[0145] Color filters CF_R, CF_G, and CF_B of the same color are disposed on the corresponding organic light emitting layer 312 to prevent color mixing in the corresponding light emitting regions PXA_R, PXA_G, and PXA_B and to increase color reproducibility. In addition, since the color filters CF_R, CF_G, and CF_B absorb external light at a considerable level, external light reflection can be reduced even without additionally providing a polarizing plate or the like.

[0146] The color filters CF_R, CF_G, and CF_B not only transmit the light generated from the organic light emitting diode, but also reduce the reflection of the light incident from the outside. When the external light passes through the color filters CF_R, CF_G, and CF_B, the amount of light is reduced to about 1 / 3. The light that has passed through the color filters CF_R, CF_G, and CF_B is partially eliminated and partially reflected from the components (e.g., the light emitting element layer 30 and the encapsulation layer 40) arranged below the color filters CF_R, CF_G, and CF_B. The reflected light is incident on the color filters CF_R, CF_G, and CF_B again. When the reflected light passes through the color filters CF_R, CF_G, and CF_B, the brightness of the reflected light is reduced. Therefore, only a portion of the external light is reflected from the organic light emitting display device 1. In other words, the external light reflection is reduced.

[0147] Each of the color filters CF_R, CF_G, and CF_B may include an organic material. In an exemplary embodiment, the refractive index of each of the color filters CF_R, CF_G, and CF_B may be higher than the refractive index of the touch insulating layer 511. In other words, each of the color filters CF_R, CF_G, and CF_B may include a relatively dense material, and the touch insulating layer 511 may include a relatively sparse material. For example, when the touch insulating layer 511 has a refractive index of about 1.53, each of the color filters CF_R, CF_G, and CF_B may have a refractive index of about 1.65. When the refractive index of each of the color filters CF_R, CF_G, and CF_B is higher than the refractive index of the touch insulating layer 511, the light converging effect of the lateral light may be enhanced, and the light captured by the interface of the encapsulation layer 450 may be extracted, thereby increasing the total amount of light.

[0148] The second buffer layer 501, the first touch conductive layer and the second touch conductive layer, and the touch insulating layer 511 may correspond to Figure 3 In addition, the black matrix BM, the liquid repellent material layer LR, and the color filters CF_R, CF_G, and CF_B may correspond to Figure 3 An anti-reflection layer 60 is provided.

[0149] A window substrate 701 may be disposed on the liquid-repellent material layer LR and the color filters CF_R, CF_G, and CF_B. The window substrate 701 may be a transparent substrate such as a glass substrate or a plastic substrate.

[0150] The window substrate 701 may correspond to Figure 3The window substrate 701 may be attached to the liquid repellent material layer LR and the color filters CF_R, CF_G, and CF_B by an adhesive member 710, wherein the adhesive member 710 is interposed between the window substrate 701 and the liquid repellent material layer LR and the color filters CF_R, CF_G, and CF_B. The adhesive member 710 may include an adhesive film, such as an optically clear adhesive (OCA) film. As another example, the adhesive member 710 may include an optically clear resin (OCR) film.

[0151] In the following, reference will be made to Figures 10 to 12 Describes the brightness ratio of the lens area with respect to the width and the cone angle (θ) according to the colors of the light emitting areas PXA_R, PXA_G, and PXA_B.

[0152] Fig.10 is a graph of the brightness ratio of the lens area relative to the width for red light at multiple cone angles. Fig.11 It is a graph of the brightness ratio of the lens area relative to the width for green light at multiple cone angles. Fig.12 is a graph of the brightness ratio of the lens area relative to the width for blue light at multiple cone angles.

[0153] refer to Figures 10 to 12 In the case of red light, regardless of the cone angle, when the width of the lens area RA is about 20 μm to about 26 μm, the lens area RA has a large brightness ratio. As the cone angle (θ) decreases, the maximum value of the brightness ratio increases.

[0154] In the case of green light, when the width of the lens area RA is about 12 μm to about 21 μm, the lens area RA has a large brightness ratio. As the cone angle (θ) decreases, the maximum value of the brightness ratio increases.

[0155] In the case of blue light, when the width of the lens area RA is about 21 μm to about 26 μm, the lens area RA has a large brightness ratio. As the cone angle (θ) decreases, the maximum value of the brightness ratio increases.

[0156] To this end, the area of ​​the lens area RA may increase in the order of the green light emitting area, the red light emitting area, and the blue light emitting area. Similarly, the width of the lens area RA may increase in the order of the green light emitting area, the red light emitting area, and the blue light emitting area.

[0157] Hereinafter, a process of laminating the touch layer 50 and the anti-reflection layer 60 will be described.

[0158] Fig.13 and Fig.14 is a cross-sectional view illustrating a process of manufacturing a touch layer and an anti-reflection layer of an organic light emitting display device according to an embodiment.

[0159] refer to Fig.13 , an insulating material layer 511a is formed on the second buffer layer 501. The insulating material layer 511a may include the materials listed in the description of the touch insulating layer 511. The insulating material layer 511a may be applied by slit coating, spin coating, gravure printing, etc. For example, in an exemplary embodiment, the insulating material layer 511a may be stacked by using chemical vapor deposition (CVD) using a chemical reaction.

[0160] The insulating material layer 511a may include a photosensitive material. The photosensitive material may be a positive photosensitive material or a negative photosensitive material. In the present exemplary embodiment, the case where the insulating material layer 511a includes a negative photosensitive material is exemplified.

[0161] Subsequently, a photoresist layer (not shown) is formed on the insulating material layer 511a. The photoresist layer may include a fluorinated acrylic monomer, a fluorinated alkyl monomer material, or a hydrophobic fluorinated silane accelerator. The photoresist layer may be a negative photoresist layer or a positive photoresist layer.

[0162] Subsequently, a mask 800 is disposed on the photoresist layer, and the photoresist layer is irradiated with light through the mask 800. The mask 800 may be, for example, a multi-tone mask 800. The multi-tone mask 800 includes a light-transmitting portion 801 that transmits most of the applied light and a multi-light-transmitting portion 802 that transmits a portion of the applied light and blocks a portion of the applied light. In the multi-light-transmitting portion 802, the amount of transmitted light may decrease toward the inside of the multi-light-transmitting portion 802.

[0163] The light-transmitting portion 801 corresponds to the area where the flat area FA is to be formed, and the multi-light-transmitting portion 802 corresponds to the area where the lens area RA is to be formed. Figure 6 ) can be completed by an exposure process and a development process.

[0164] refer to Fig.14 , a dam portion and color filters CF_R, CF_G, and CF_B may be sequentially formed on the touch insulating layer 511 .

[0165] The dam may be formed by sequentially stacking a second touch conductive layer, a black matrix BM, and a liquid repellent material layer LR.

[0172] In addition, the plane shape of the lens area RA_2 may be an irregular shape.

[0175] The touch insulating layer 511_1 of the organic light-emitting display device 2 according to another exemplary embodiment may include a flat area FA and a lens area RA. In the lens area RA, the second height H2 of the touch insulating layer 511_1 may decrease from a boundary between the flat area FA and the lens area RA toward the inside of the lens area RA. The second height H2 of the touch insulating layer 511_1 may be zero at the center of the lens area RA.

[0176] Fig.18 is a cross-sectional view of a portion of an organic light emitting display device according to another exemplary embodiment. Fig.18 yes Figure 6 's modified example.

[0177] refer to Fig.18 According to another exemplary embodiment, an organic light emitting display device 3 and Figure 6 The organic light emitting display device 1 is different in that the touch insulation layer 511_2 is composed of a plurality of insulation patterns spaced apart from each other.

[0178] The touch insulation layer 511_2 of the organic light emitting display device 3 according to this exemplary embodiment may include a plurality of insulation patterns, each of the plurality of insulation patterns may include a flat area FA, and a lens area RA may be formed between adjacent insulation patterns.

[0179] Adjacent insulating patterns may be spaced apart from each other with respect to the lens area RA. The lens area RA may expose a portion of an upper surface of the second buffer layer 501. The second buffer layer 501 and the color filters CF_R, CF_G, and CF_B may include portions directly contacting each other.

[0180] Fig.19 is a cross-sectional view of a portion of an organic light emitting display device according to another exemplary embodiment. Fig.19 yes Figure 6 's modified example.

[0181] refer to Fig.19 According to another exemplary embodiment, an organic light emitting display device 4 and Figure 6 The organic light emitting display device 1 is different in that the touch insulation layer 511_3 has a substantially flat surface at the center of the lens area RA.

[0182] The inclination of the touch insulation layer 511_3 of the organic light emitting display device 4 according to this exemplary embodiment may become gentler toward the center of the lens area RA. An upper surface of the touch insulation layer 511_3 may be substantially flat in a portion of the lens area RA including the center thereof.

[0183] Fig. 20 is a cross-sectional view of a portion of an organic light emitting display device according to another exemplary embodiment. Fig. 20 yes Figure 6 's modified example.

[0184] refer to Fig. 20 According to another exemplary embodiment, an organic light emitting display device 5 and Figure 6 The organic light emitting display device 1 is different in that the lens area RA of the touch insulation layer 511_4 has a convex lens shape.

[0185] The touch insulation layer 511_4 of the organic light-emitting display device 5 according to this embodiment has an upper surface with varying heights, and includes a flat area FA having a first height H1 and a lens area RA having a second height H2 greater than the first height H1.

[0186] In the lens area RA, the cross section of the touch insulation layer 511_4 may have a convex lens shape. The cross section of the lens area RA may have a shape in which the thickness becomes thicker toward the center of the lens area RA. The lens area RA may basically function as a convex lens.

[0187] The height of the upper surface of the touch insulation layer 511_4 may gradually increase from the boundary between the flat area FA and the lens area RA toward the inside of the lens area RA. The height of the upper surface of the touch insulation layer 511_4 may be highest at the center of the lens area RA.

[0188] A second-order derivative value of the height of the upper surface of the touch insulation layer 511_4 with respect to the distance from the boundary between the flat area FA and the lens area RA may be generally negative.

[0189] A dam may be provided on the flat area FA of the touch insulating layer 511_4. The dam may have a structure in which the second touch conductive layer, the black matrix BM, and the liquid repellent material layer LR are stacked in sequence. The dam may include a plurality of second openings L2_1, L2_2, and L2_3 exposing a portion of the touch insulating layer 511_4. In an embodiment, the widths of the second openings L2_1, L2_2, and L2_3 may be narrower than the widths of the first openings L1_1, L1_2, and L1_3, but the present invention is not limited thereto.

[0190] The width of the black matrix BM may be greater than the width of the pixel defining layer PDL. In other words, the pixel defining layer PDL may be overlapped in the black matrix BM. The width of the black matrix BM may be formed to be wider than the width of the pixel defining layer PDL to reduce reflection of external light.

[0191] A cross-section of the lens area RA may be formed to have a convex lens shape to increase a converging effect of light emitted from the organic light emitting diode.

[0192] Light emitted from the organic light emitting layer 312 may be converged by the cross-sectional shape of the lens area RA. The color filters CF_R, CF_G, and CF_B may be formed of a material that is less dense than that of the organic light emitting layer 312 so that light converged by refraction may be diverged again.

[0193] Therefore, the reflection, viewing angle, and brightness ratio of light emitted from the organic light emitting diode may be increased.

[0194] The dam portion may be formed so that the black matrix BM covers the mesh pattern of each of the sensing electrodes IE1 and IE2. In a plan view, the black matrix BM may occupy a relatively large area compared to the area of ​​the mesh pattern of each of the sensing electrodes IE1 and IE2. Therefore, as the area of ​​the black matrix BM increases, external light reflection of the organic light emitting display device 5 may be reduced.

[0195] As described above, according to the exemplary embodiments of the present invention, the organic light emitting display device can ensure a large viewing angle and a large brightness ratio.

[0196] In addition, the organic light emitting display device can reduce external light reflection caused by the touch electrode.

[0197] Furthermore, in manufacturing an organic light emitting display device, the number of masks can be reduced.

[0198] Although certain exemplary embodiments and implementations have been described herein, other embodiments and modifications will be apparent from this description. Therefore, the inventive concept is not limited to such embodiments, but rather to the broader scope of the appended claims and to various obvious modifications and equivalent arrangements that will be apparent to those of ordinary skill in the art.
