FIG. 4 is a cross-sectional view taken along the line I-I' of FIG. 2. FIG. 5 is a cross-sectional view taken along the line II-II' of FIG. 3.

[0029] Referring to FIGS. 1 to 5, a touch display device according to an embodiment of the present invention may include a device substrate (110). The device substrate (110) may include an insulating material. For example, the device substrate (110) may include glass or plastic. The device substrate (110) may include a display area (AA) and a bezel area (BZ) located outside the display area (AA). For example, the bezel area (BZ) may surround the display area (AA).

[0030] The display area (AA) of the above-described device substrate (110) can implement an image provided to a user. For example, a plurality of pixel areas (PA) may be located within the display area (AA) of the above-described device substrate (110). The pixel areas (PA) may be located side by side in a first direction and a second direction perpendicular to the first direction. Two pixel areas (PA) adjacent in the first direction may be arranged in an alternating manner. Two pixel areas (PA) adjacent in the second direction may be arranged in an alternating manner. Each pixel area (PA) may implement a color different from that of adjacent pixel areas (PA). For example, a touch display device according to an embodiment of the present invention may have a pentile structure in which a first row in which red pixel areas (R) and blue pixel areas (B) are alternately located and a second row in which green pixel areas (G) are located are repeated in an alternating manner.

[0031] In each pixel area (PA), light exhibiting a specific color may be emitted. For example, within each pixel area (PA), a pixel driving circuit and a light-emitting element (130) electrically connected to the pixel driving circuit may be located.

[0032] The pixel driving circuit may be connected to one of the gate lines (GL) that apply a gate signal and one of the data lines (DL) that apply a data signal. For example, the pixel driving circuit may generate a driving current corresponding to the data signal according to the gate signal. The driving current generated by the pixel driving circuit may be supplied to the light-emitting element (130) for one frame. For example, the pixel driving circuit may include a switching thin-film transistor (T1), a driving thin-film transistor (T2), and a storage capacitor (Cst).

[0033] The switching thin-film transistor (T1) can transmit the data signal to the driving thin-film transistor (T2) according to the gate signal. The driving thin-film transistor (T2) can generate the driving current. For example, the driving thin-film transistor (T2) may include a semiconductor pattern (121), a gate insulating film (122), a gate electrode (123), a source electrode (124), and a drain electrode (125).

[0034] The semiconductor pattern (121) may include a semiconductor material. For example, the semiconductor pattern (121) may include at least one of amorphous silicon, polycrystalline silicon, and oxide semiconductor. The semiconductor pattern (121) may include a source region, a drain region, and a channel region. The channel region may be located between the source region and the drain region. The source region and the drain region may have lower resistance than the channel region. For example, the source region and the drain region may include a conductive region of the oxide semiconductor.

[0035] The gate insulating film (122) may be located on the semiconductor pattern (121). For example, the gate insulating film (122) may overlap with the channel region of the semiconductor pattern (121). The source region and the drain region of the semiconductor pattern (121) may be located outside the gate insulating film (122). The gate insulating film (122) may include an insulating material. For example, the gate insulating film (122) may include an inorganic insulating material such as silicon oxide (SiO) and silicon nitride (SiN).

[0036] The gate electrode (123) may be located on the gate insulating film (122). For example, the gate electrode (123) may overlap with the channel region of the semiconductor pattern (121). The gate electrode (123) may be insulated from the semiconductor pattern (121) by the gate insulating film (122). For example, the side of the gate insulating film (122) may be continuous with the side of the semiconductor pattern (123). The gate electrode (123) may include a conductive material. For example, the gate electrode (123) may include a metal such as aluminum (Al), titanium (Ti), copper (Cu), molybdenum (Mo), tantalum (Ta), chromium (Cr), and tungsten (W). The channel region of the semiconductor pattern (121) may have electrical conductivity corresponding to the voltage applied to the gate electrode (123).

[0037] The source electrode (124) may include the conductive material. For example, the source electrode (124) may include a metal such as aluminum (Al), titanium (Ti), copper (Cu), molybdenum (Mo), tantalum (Ta), chromium (Cr), and tungsten (W). The source electrode (124) may be insulated from the gate electrode (123). The source electrode (124) may be located on a different layer from the gate electrode (123). For example, an interlayer insulating film (112) covering the gate electrode (123) may be located on the device substrate (110), and the source electrode (124) may be located on the interlayer insulating film (112). The interlayer insulating film (112) may include an insulating material. For example, the interlayer insulating film (112) may include an inorganic insulating material such as silicon oxide (SiO) and silicon nitride (SiN).

[0038] The source electrode (124) may be electrically connected to the source region of the semiconductor pattern (121). For example, the interlayer insulating film (112) may include a source contact hole that partially exposes the source region of the semiconductor pattern (121). The source electrode (124) may come into direct contact with the source region of the semiconductor pattern (121) through the source contact hole.

[0039] The drain electrode (125) may include a conductive material. For example, the drain electrode (125) may include a metal such as aluminum (Al), titanium (Ti), copper (Cu), molybdenum (Mo), tantalum (Ta), chromium (Cr), and tungsten (W). The drain electrode (125) may be insulated from the gate electrode (123). The drain electrode (125) may be located on a different layer from the gate electrode (123). For example, the drain electrode (125) may be located on the interlayer insulating film (112). The drain electrode (125) may be located on the same layer as the source electrode (124). The drain electrode (125) may include the same material as the source electrode (124). For example, the drain electrode (125) may be formed simultaneously with the source electrode (124).

[0040] The drain electrode (125) may be electrically connected to the drain region of the semiconductor pattern (121). For example, the interlayer insulating film (112) may include a drain contact hole that partially exposes the drain region of the semiconductor pattern (121). The drain electrode (125) may come into direct contact with the drain region of the semiconductor pattern (121) through the drain contact hole.

[0041] The switching thin-film transistor (T1) may have the same structure as the driving thin-film transistor (T2). For example, the switching thin-film transistor (T1) may include a gate electrode electrically connected to the corresponding gate line (GL), a source electrode electrically connected to the corresponding data line (DL), and a drain electrode electrically connected to the gate electrode (123) of the driving thin-film transistor (T2). The source electrode (124) of the driving thin-film transistor (T2) may be connected to a first power supply voltage supply line (VDD) that supplies a positive power supply voltage. The storage capacitor (Cst) may maintain the voltage applied to the gate electrode (123) of the driving thin-film transistor (T2) for one frame. For example, the storage capacitor (Cst) may be connected between the gate electrode (123) and the drain electrode (125) of the driving thin-film transistor (T2).

[0042] The light-emitting element (130) can emit light using the driving current supplied from the pixel driving circuit. For example, the light-emitting element (130) may include a first light-emitting electrode (131), a light-emitting stack (132), and a second light-emitting electrode (133) stacked in order on the element substrate (110).

[0043] The first light-emitting electrode (131) may be electrically connected to the drain electrode (125) of the driving thin-film transistor (T2). For example, the driving current generated by the pixel driving circuit may be supplied to the first light-emitting electrode (131) of the light-emitting element (130). The first light-emitting electrode (131) may include a conductive material. The first light-emitting electrode (131) may include a material having high reflectivity. For example, the first light-emitting electrode (131) may include metals such as aluminum (Al), titanium (Ti), copper (Cu), molybdenum (Mo), tantalum (Ta), chromium (Cr), and tungsten (W). The first light-emitting electrode (131) may have a multilayer structure. For example, the first light-emitting electrode (131) may have a structure in which a reflective electrode made of metal is positioned between transparent conductive layers made of transparent conductive materials such as ITO and IZO.

[0044] The light-emitting stack (132) can generate light of brightness corresponding to the voltage difference between the first light-emitting electrode (131) and the second light-emitting electrode (133). For example, the light-emitting stack (132) may include an emission material layer (EML) containing a light-emitting material. The light-emitting material may include an organic material, an inorganic material, or a hybrid material. For example, a touch display device according to an embodiment of the present invention may be an organic light-emitting display device containing an organic light-emitting material.

[0045] The light-emitting stack (132) may have a multilayer structure. For example, the light-emitting stack (132) may further include at least one of a hole injection layer (HIL), a hole transport layer (HTL), an electron transport layer (HTL), and an electron injection layer (HIL). The light-emitting stack (132) may include a plurality of light-emitting material layers. For example, the light-emitting stack (132) may include a charge generation layer (CGL) located between a first light-emitting material layer and a second light-emitting material layer. The second light-emitting material layer may include a material different from the first light-emitting material layer.

[0046] The second light-emitting electrode (133) may include a conductive material. The second light-emitting electrode (133) may have a higher transmittance than the first light-emitting electrode (131). For example, the second light-emitting electrode (133) may be a transparent electrode made of a transparent conductive material. The second light-emitting electrode (133) may include a transparent conductive oxide such as ITO, IZO, and AZO. Accordingly, in a touch display device according to an embodiment of the present invention, light generated by the light-emitting stack (132) of each pixel area (PA) may be emitted to the outside through the second light-emitting electrode (133) of the corresponding pixel area (PA).

[0047] A device buffer film (111) may be positioned between the device substrate (110) and the pixel driving circuit of each pixel area (PA). The device buffer film (111) can prevent contamination by the device substrate (110) during the formation process of the pixel driving circuits. The device buffer film (111) may extend onto the non-display area (NA) of the device substrate (110). For example, the upper surface of the device substrate (110) facing the pixel driving circuit of each pixel area (PA) may be completely covered by the device buffer film (111). The device buffer film (111) may include an insulating material. For example, the device buffer film (111) may include an inorganic insulating material such as silicon oxide (SiO) and silicon nitride (SiN). The device buffer film (111) may have a multilayer structure. For example, the above-mentioned device buffer film (111) may have a stacked structure of an inorganic insulating film made of silicon oxide (SiO) and an inorganic insulating film made of silicon nitride (SiN).

[0048] A planarization film (113) may be positioned between the pixel driving circuit of each pixel area (PA) and the light-emitting element (130). The planarization film (113) may eliminate the step difference caused by the pixel driving circuit of each pixel area (PA). For example, the upper surface of the planarization film (113) facing the element substrate (110) may be a flat plane. The switching thin-film transistor (T1), the driving thin-film transistor (T2), and the storage capacitor (Cst) located within each pixel area (PA) may be covered by the planarization film (113). The planarization film (113) may include an insulating material. The planarization film (113) may include a material different from the interlayer insulating film (112). For example, the planarization film (113) may include an organic insulating material.

[0049] The first light-emitting electrode (131) of each pixel region (PA) can penetrate the planarization film (113) and be electrically connected to the pixel driving circuit of the corresponding pixel region (PA). For example, the planarization film (113) may include pixel contact holes that partially expose the drain electrode (125) of the driving thin-film transistor (T2) located within each pixel region (PA). The first light-emitting electrode (131) of each pixel region (PA) can come into direct contact with the drain electrode (125) of the driving thin-film transistor (T2) located within the corresponding pixel region (PA) through one of the pixel contact holes.

[0050] The first light-emitting electrode (131) of each pixel area (PA) may be insulated from the first light-emitting electrode (131) of an adjacent pixel area (PA). The first light-emitting electrode (131) of each pixel area (PA) may be spaced apart from the first light-emitting electrode (131) of an adjacent pixel area (PA). For example, a bank insulating film (114) may be located between the first light-emitting electrodes (131) of adjacent pixel areas (PA). The bank insulating film (114) may include an insulating material. For example, the bank insulating film (114) may include an organic insulating material. The bank insulating film (114) may cover the edges of the first light-emitting electrode (131) located within each pixel area (PA). The light-emitting stack (132) and the second light-emitting electrode (133) of each pixel area (PA) may be laminated on a portion of the corresponding first light-emitting electrode (131) exposed by the bank insulating film (114). For example, the bank insulating film (114) may define light-emitting regions (BEA, GEA, REA) within each pixel area (PA).

[0051] The light-emitting element (130) of each pixel area (PA) may have the same structure as the light-emitting element (130) of an adjacent pixel area (PA). For example, the light-emitting stack (132) of each pixel area (PA) may be connected to the light-emitting stack (132) of an adjacent pixel area (PA) by extending along the surface of the bank insulating film (114). The light emitted from the light-emitting element (130) of each pixel area (PA) may exhibit the same color as the light emitted from the light-emitting element (130) of an adjacent pixel area (PA). For example, the light-emitting stack (132) of each pixel area (PA) may emit white light. The light-emitting stack (132) of each pixel area (PA) may be formed simultaneously with the light-emitting stack (132) of an adjacent pixel area (PA). Accordingly, in a touch display device according to an embodiment of the present invention, the process of forming the light-emitting stack (132) on each pixel area (PA) may be simplified.

[0052] The voltage applied to the second light-emitting electrode (133) of each pixel area (PA) may be the same as the voltage applied to the second light-emitting electrode (133) of an adjacent pixel area (PA). For example, the second light-emitting electrode (133) of each pixel area (PA) may be electrically connected to a second power supply voltage supply line (VSS) that supplies a negative power supply voltage. Accordingly, in a touch display device according to an embodiment of the present invention, the brightness of light emitted from the light-emitting element (130) of the corresponding pixel area (PA) can be controlled through the data signal applied to each pixel area (PA). The second light-emitting electrode (133) of each pixel area (PA) may be electrically connected to the second light-emitting electrode (133) of an adjacent pixel area (PA). For example, the second light-emitting electrode (133) of each pixel area (PA) may be in direct contact with the second light-emitting electrode (133) of an adjacent pixel area (PA). The second light-emitting electrode (133) of each pixel area (PA) can be formed simultaneously with the second light-emitting electrode (133) of an adjacent pixel area (PA). Accordingly, in a touch display device according to an embodiment of the present invention, the process of forming the second light-emitting electrode (133) on each pixel area (PA) can be simplified.

[0053] An encapsulation unit (140) may be positioned on the light-emitting element (130) of each pixel area (PA). The encapsulation unit (140) may prevent damage to the light-emitting elements (130) by external moisture and / or oxygen. The light-emitting element (130) of each pixel area (PA) may be completely covered by the encapsulation unit (140). For example, the encapsulation unit (140) may extend onto the bezel area (BZ) of the element substrate (110).

[0054] The above-described sealing unit (140) may include at least one inorganic sealing layer (141, 143) and at least one organic sealing layer (142). For example, the sealing unit (140) may have a structure in which at least one organic sealing layer (142) is located between the inorganic sealing layers (141, 143). The top layer of the sealing unit (140) may be the inorganic sealing layer (141, 143). For example, the top surface and side surface of the organic sealing layer (142) may be covered by the inorganic sealing layer (141, 143). Accordingly, in a touch display device according to an embodiment of the present invention, the penetration of external moisture and oxygen can be effectively blocked.

[0055] The inorganic encapsulation layer (141, 143) may include an inorganic insulating material. For example, the inorganic encapsulation layer (141, 143) may include an inorganic insulating material capable of low-temperature deposition, such as silicon nitride (SiN), silicon oxide (SiO), silicon oxynitride (SiON), and aluminum oxide (Al2O3). Accordingly, in a touch display device according to an embodiment of the present invention, damage to the light-emitting stacks (132) caused by the formation process of the inorganic encapsulation layer (141, 143) can be prevented.

[0056] The organic encapsulation layer (142) can relieve stress caused by the inorganic encapsulation layer (141, 143). For example, the organic encapsulation layer (142) may include organic insulating materials such as acrylic resin, epoxy resin, polyimide, polyethylene, and silicon oxycarbon (SiOC). Steps caused by the light-emitting elements (130) can be eliminated by the organic encapsulation layer (142). For example, the upper surface of the organic encapsulation layer (142) facing the element substrate (110) may be a flat plane.

[0057] The organic encapsulation layer (142) may be formed using an ink-jet method. For example, at least one dam (106) may be located on the bezel area (NA) of the device substrate (110). The dam (106) may block the flow of the organic encapsulation layer (142). The dam (106) may extend along the edge of the display area (AA). For example, in a touch display device according to an embodiment of the present invention, the organic encapsulation layer (142) may be formed within an area defined by the dam (106). The dam (106) may be formed using a formation process of at least one of the insulating films located between the device substrate (110) and the encapsulation unit (140). For example, the dam (106) may be formed simultaneously with the planarization layer (113). The dam (106) may include the same material as the flattening layer (113). For example, the dam (106) may include an organic insulating material. The interlayer insulating film (112) may extend onto the bezel region (BZ) of the device substrate (110). For example, the dam (106) may be located on the interlayer insulating film (112). The thickness of the dam (106) may be the same as the thickness of the flattening layer (112).

[0058] A touch sensor (Cm) may be positioned on the above-mentioned bag unit (140). The touch sensor (Cm) may detect a touch by a user and / or a tool. For example, the touch sensor (Cm) may detect the presence or absence of a touch and the location of the touch through a change in mutual capacitance. The touch sensor (Cm) may include a first touch line (310) and a second touch line (320).

[0059] A touch driving signal may be applied to the first touch line (310). For example, the first touch line (310) may function as a touch driving line. The first touch line (310) may include first touch electrodes (311) and first bridge electrodes (312). The first touch electrodes (311) may be positioned side by side on the encapsulation unit (140). The first bridge electrodes (312) may electrically connect the first touch electrodes (311). Each first bridge electrode (312) may extend in a first direction. For example, each first touch electrode (311) may be connected to a first touch electrode (311) adjacent in the first direction by one of the first bridge electrodes (312).

[0060] The first touch electrodes (311) may include a conductive material. The first touch electrodes (311) may include a material having relatively low resistance. For example, the first touch electrodes (311) may include metals such as titanium (Ti), copper (Cu), molybdenum (Mo), and tantalum (Ta). Each first touch electrode (311) may have a multilayer structure. For example, the first touch electrodes (311) may have a triple layer structure such as Ti / Al / Ti, MoTi / Cu / MoTi, and Ti / Al / Mo.

[0061] The first bridge electrodes (312) may include a conductive material. The first bridge electrodes (312) may include a material having relatively low resistance. For example, the first bridge electrodes (312) may include metals such as titanium (Ti), copper (Cu), molybdenum (Mo), and tantalum (Ta). The first bridge electrodes (312) may include the same material as the first touch electrodes (311). Each first bridge electrode (312) may have a multilayer structure. For example, the first bridge electrodes (312) may have a triple layer structure such as Ti / Al / Ti, MoTi / Cu / MoTi, and Ti / Al / Mo. The first bridge electrodes (312) may have the same structure as the first touch electrodes (311). The first bridge electrodes (312) may be located on the same layer as the first touch electrodes (31). For example, each first bridge electrode (312) may be in direct contact with the corresponding first touch electrodes (311).

[0062] The second touch line (320) may include second touch electrodes (321) and second bridge electrodes (322). The second touch electrodes (321) may be positioned side by side on the encapsulation unit (140). The second touch electrodes (321) may be positioned on the same layer as the first touch electrodes (311). The second touch electrodes (321) may be insulated from the first touch electrodes (311). For example, the second touch electrodes (321) may be positioned between the first touch electrodes (311). The second touch electrodes (321) may have the same shape as the first touch electrodes (311). For example, the first touch electrodes (311) and the second touch electrodes (312) may be arranged alternately on the encapsulation unit (140). Accordingly, in a touch display device according to an embodiment of the present invention, the charge charged by the touch driving signal may be discharged through the second touch line (320). For example, the second touch line (320) may function as a touch sensing line. Thus, a touch display device according to an embodiment of the present invention can detect whether a user and / or tool has touched and the location of the touch using the touch sensor (Cm).

[0063] The second touch electrodes (321) may include a conductive material. The second touch electrodes (321) may include a material having relatively low resistance. For example, the second touch electrodes (321) may include metals such as titanium (Ti), copper (Cu), molybdenum (Mo), and tantalum (Ta). The second touch electrodes (321) may include the same material as the first touch electrodes (311). Each second touch electrode (321) may have a multilayer structure. For example, the second touch electrodes (321) may have a triple layer structure such as Ti / Al / Ti, MoTi / Cu / MoTi, and Ti / Al / Mo. The second touch electrodes (321) may have the same structure as the first touch electrodes (311).

[0064] The second touch electrodes (321) may be located on the same layer as the first touch electrodes (311) and the first bridge electrodes (312). The second touch electrodes (321) may be insulated from the first bridge electrodes (312). The second touch electrodes (321) may be spaced apart from the first bridge electrodes (312). For example, the first bridge electrodes (312) may cross between the second touch electrodes (321).

[0065] The second bridge electrodes (322) can electrically connect the second touch electrodes (321). Each second bridge electrode (322) can extend in a second direction. For example, each second touch electrode (321) can be connected to an adjacent second touch electrode (321) in the second direction by one of the second bridge electrodes (322). The second direction may be different from the first direction. For example, the second direction may be perpendicular to the first direction. The second bridge electrodes (322) can cross between the first touch electrodes (311). For example, each second bridge electrode (322) may cross one of the first bridge electrodes (312). The second bridge electrodes (322) may be insulated from the first bridge electrodes (312). The second bridge electrodes (321) may be located on a different layer from the first bridge electrodes (312). For example, the touch sensor (Cm) includes a touch insulating film (350) located on the second bridge electrodes (322), and the first touch electrodes (311), the first bridge electrodes (312), and the second touch electrodes (321) may be located on the touch insulating film (350).

[0066] The touch insulating film (350) may include an insulating material. For example, the touch insulating film (350) may include an inorganic insulating material such as silicon oxide (SiO) and silicon nitride (SiN). The touch insulating film (350) may include touch contact holes that partially expose each second bridge electrode (322). Each second touch electrode (321) may be connected to the corresponding second bridge electrode (322) through one of the touch contact holes.

[0067] The second bridge electrodes (322) may include a conductive material. The second bridge electrodes (322) may include a material having relatively low resistance. For example, the second bridge electrodes (322) may include metals such as titanium (Ti), copper (Cu), molybdenum (Mo), and tantalum (Ta). Each second bridge electrode (322) may have a multilayer structure. For example, the second bridge electrodes (322) may have a triple layer structure such as Ti / Al / Ti, MoTi / Cu / MoTi, and Ti / Al / Mo.

[0068] The first touch electrodes (311), the first bridge electrodes (312), the second touch electrodes (321), and the second bridge electrodes (322) of the touch sensor (Cm) may be located within the display area (AA) of the device substrate (110). The light-emitting area (BEA, GEA, REA) of each pixel area (PA) may be located between the first touch electrodes (311), the first bridge electrodes (312), the second touch electrodes (321), and the second bridge electrodes (322b). The first touch line (310) and the second touch line (320) may be located outside the light-emitting elements (130). For example, the first touch electrodes (311), the first bridge electrodes (312), the second touch electrodes (321), and the second bridge electrodes (322) may overlap with the bank insulating film (114). The plane of each first touch electrode (311) and the plane of each second touch electrode (321) may have a mesh shape including openings that overlap with the light-emitting regions (BEA, GEA, REA) of each pixel region (PA). Accordingly, in a touch display device according to an embodiment of the present invention, the accuracy of touch detection using the touch sensor (Cm) is improved, and the reduction in light extraction efficiency by the first touch electrodes (311), the first bridge electrodes (312), the second touch electrodes (321), and the second bridge electrodes (322) of the touch sensor (Cm) can be minimized.

[0069] A touch buffer film (200) may be positioned between the above-mentioned encapsulation unit (140) and the above-mentioned touch sensor (Cm). For example, the above-mentioned second bridge electrodes (322) may be positioned between the above-mentioned touch buffer film (200) and the above-mentioned touch insulating film (350). The above-mentioned touch buffer film (200) may reduce parasitic capacitance occurring between the above-mentioned second light-emitting electrode (133) of each light-emitting element (130) and the above-mentioned touch sensor (Cm). For example, the distance between the above-mentioned first touch line (310) of the above-mentioned touch sensor (Cm) and the above-mentioned second light-emitting electrode (133) of each light-emitting element (130), and the distance between the above-mentioned second touch line (320) of the above-mentioned touch sensor (Cm) and the above-mentioned second light-emitting electrode (133) of each light-emitting element (130) may be increased by the above-mentioned touch buffer film (200). Accordingly, in a touch display device according to an embodiment of the present invention, the accuracy of touch detection by the touch sensor (Cm) can be improved. The touch buffer film (200) may include an insulating material. For example, the touch buffer film (200) may include an inorganic insulating material such as silicon oxide (SiO) and silicon nitride (SiN).

[0070] A touch protective film (370) may be positioned on the touch sensor (Cm). The touch protective film (370) may prevent damage to the touch sensor (Cm) caused by external impact and / or moisture. For example, the first touch electrodes (311), the first bridge electrodes (312), and the second touch electrodes (321) may be covered by the touch protective film (370). The touch protective film (370) may be in direct contact with the touch insulating film (350) on the outside of the first touch line (310) and the second touch line (320). The touch protective film (370) may include an insulating material. For example, the touch protective film (370) may include an inorganic insulating material such as silicon oxide (SiO) and silicon nitride (SiN).

[0071] A light-blocking pattern (410) may be positioned on the touch protective film (370). The light-blocking pattern (410) may have a lower reflectance than the first touch electrodes (311), the first bridge electrodes (312), and the second touch electrodes (321). Accordingly, in a touch display device according to an embodiment of the present invention, external light reflection by the first touch electrodes (311), the first bridge electrodes (312), and the second touch electrodes (321) can be reduced by the light-blocking pattern (410). Therefore, in a touch display device according to an embodiment of the present invention, image degradation due to external light reflection can be minimized.

[0072] The light-blocking pattern (410) may include a conductive material. The light-blocking pattern (410) may include a metal such as molybdenum (Mo), titanium (Ti), tungsten (W), and copper (Cu) which has a relatively low reflectivity. For example, the light-blocking pattern (410) may be formed from one of MoTi, MoO, Ti, TiO, CuSi, and MoW. The light-blocking pattern (410) may be electrically connected to the first touch electrodes (311) and the second touch electrodes (321). For example, the light-blocking pattern (410) may include a first light-blocking pattern (411) electrically connected to the first touch electrodes (311) and the first bridge electrodes (312), and a second light-blocking pattern (412) electrically connected to the second touch electrodes (321). The second light-blocking pattern (412) may include the same material as the first light-blocking pattern (411). The second light-blocking pattern (412) may be located on the same layer as the first light-blocking pattern (411). For example, the second light-blocking pattern (412) may be formed simultaneously with the first light-blocking pattern (411). Accordingly, in a touch display device according to an embodiment of the present invention, the resistance of the first touch line (310) and the second touch line (320) may be reduced. Therefore, in a touch display device according to an embodiment of the present invention, the reliability of touch detection may be improved.

[0073] The first light-blocking pattern (411) may be located only on the first touch electrodes (311) and the first bridge electrodes (312). For example, the planar shape of the first light-blocking pattern (411) may be identical to the planar shape formed by the first touch electrodes (311) and the first bridge electrodes (312). The plane of the first light-blocking pattern (410) may have a mesh shape. The second light-blocking pattern (412) may be located only on the second touch electrodes (321). For example, the planar shape of the second light-blocking pattern (412) may be identical to the planar shape of the second touch electrodes (321). The plane of the second light-blocking pattern (412) may have a mesh shape. The second light-blocking pattern (412) may be spaced apart from the first light-blocking pattern (411). For example, the light-blocking pattern (410) may include a gap (410g) that overlaps with the spaced-out area between the first touch electrodes (311) and the second touch electrodes (321).

[0074] The first light-blocking pattern (411) and the second light-blocking pattern (412) may be located outside the light-emitting elements (130). For example, the first light-blocking pattern (411) and the second light-blocking pattern (412) may extend between the light-emitting regions (BEA, GEA, REA). Accordingly, in a touch display device according to an embodiment of the present invention, the area of ​​the light-emitting regions (BEA, GEA, REA) may not be affected by the light-blocking pattern (410). Therefore, in a touch display device according to an embodiment of the present invention, the resistance of the first touch line (310) and the second touch line (320) may be lowered without reducing the area of ​​the light-emitting regions (BEA, GEA, REA).

[0075] An upper protective film (390) may be positioned on the light-blocking pattern (410). The upper protective film (390) can prevent damage to the light-blocking pattern (410) caused by external impact and moisture. The upper protective film (390) may include an insulating material. For example, the upper protective film (390) may include an inorganic insulating material such as silicon oxide (SiO) and silicon nitride (SiN). The upper protective film (390) may extend outward from the light-blocking pattern (410). For example, the upper protective film (390) may come into direct contact with the touch protective film (370) on the outside of the light-blocking pattern (410).

[0076] Color filters (420b, 420g, 420r) may be positioned on the upper protective film (390). The color filters (420b, 420g, 420r) may overlap with the light-emitting regions (BEA, GEA, REA). Each light-emitting element (130) may overlap with one of the color filters (420b, 420g, 420r). For example, light generated by each light-emitting element (130) may be emitted to the outside through one of the color filters (420b, 420g, 420r). Each color filter (420b, 420g, 420r) may contain a different material from the adjacent color filter (420b, 420g, 420r). For example, blue color filters (420b) may be located on the blue light-emitting regions (BEA) of the blue pixel regions (B), green color filters (420g) may be located on the green light-emitting regions (GEA) of the green pixel regions (G), and red color filters (420r) may be located on the red light-emitting regions (REA) of the red pixel regions (R). Accordingly, a touch display device according to an embodiment of the present invention can provide an image composed of various colors to a user by using white light emitted from the light-emitting element (130) of each pixel region (PA) and the color filters (420b, 420g, 420r).

[0077] The color filters (420b, 420g, 420r) may be located within the openings of the first touch lines (311) and the second touch lines (321) having a mesh shape. For example, the light-blocking pattern (410) may surround the color filters (420b, 420g, 420r). Accordingly, in a touch display device according to an embodiment of the present invention, external light not blocked by the light-blocking pattern (410) may pass through one of the color filters (420b, 420g, 420r) and be irradiated onto the light-emitting elements (130). In addition, in a touch display device according to an embodiment of the present invention, external light reflected by the first electrode (131) of each light-emitting element (130) can pass through the color filter (420b, 420g, 420r) that overlaps with the light-emitting element (130) and be emitted to the outside. That is, in a touch display device according to an embodiment of the present invention, external light reflected by the first electrode (131) of each light-emitting element (130) can display the same color as the light emitted from the light-emitting element (130). Therefore, in a touch display device according to an embodiment of the present invention, image degradation due to external light reflection can be prevented without the use of a polarizer.

[0078] A device protective film (500) may be positioned on the color filters (420b, 420g, 420r). The device protective film (500) can prevent damage to the color filters (420b, 420g, 420r) caused by external impact and / or moisture. The device protective film (500) may extend outward from the display area (AA). For example, the color filters (420b, 420g, 420r) may be completely covered by the device protective film (500). The device protective film (500) may include an insulating material. The device protective film (500) may include a material different from the upper insulating film (390). For example, the device protective film (500) may include an organic insulating material. The step difference caused by the first touch line (310), the second touch line (320), the light-blocking pattern (410), and the color filters (420b, 420g, 420r) can be removed by the element protective film (500).

[0079] A cover member (600) may be positioned on the above-mentioned element protective film (500). The cover member (600) may prevent damage caused by external impact. The cover member (600) may come into direct contact with the element protective film (500). For example, the cover member (600) may include a cover adhesive layer (610) and a cover window (620).

[0080] The cover adhesive layer (610) may include an adhesive material. The cover adhesive layer (610) may include a transparent material. For example, the cover adhesive layer (610) may include an Optical Clear Adhesive (OCA). The cover adhesive layer (610) may mitigate external light reflection. For example, the cover adhesive layer (610) may include a dye.

[0081] The cover window (620) may be attached to the device protective film (500) by the cover adhesive layer (610). The cover window (620) may include a transparent material. The cover window (620) may have a hardness greater than a certain amount. For example, the cover window (620) may include glass or plastic.

[0082] Various signals for implementing an image can be applied to each pixel area (PA) through the bezel area (BZ) of the device substrate (110). For example, the bezel area (BZ) of the device substrate (110) may include a pad area (PD) where display pads (104) and touch pads (304) are located. The dam (106) may be located between the display area (AA) and the pad area (PD). For example, the display pads (104) and the touch pads (304) may be spaced apart from the encapsulation unit (140). Accordingly, in a touch display device according to an embodiment of the present invention, it is prevented that some of the display pads (104) and the touch pads (304) are unintentionally obscured by the organic encapsulation layer (142). Accordingly, in a touch display device according to an embodiment of the present invention, distortion of the signal transmitted through the display pads (104) and the touch pads (304) can be prevented.

[0083] The gate lines (GL) and / or the data lines (DL) may be electrically connected to the display pads (104). For example, the data signal applied to each pixel area (PA) may be transmitted through one of the display pads (104) and one of the data lines (DL). The touch pads (304) may be located side-by-side with the display pads (104). For example, the pad area (PD) may be located on one side of the display area (AA).

[0084] Each touch pad (304) may include a lower pad electrode (304a) and an upper pad electrode (304b) located on the lower pad electrode (304a). The touch pads (304) may be formed using the forming process of the pixel driving circuits, the light-emitting elements (130), and the touch sensor (Cm). For example, the lower pad electrode (304a) may include the same material as the source electrode (124) and the drain electrode (125) of each pixel driving circuit, and the upper pad electrode (304b) may include the same material as the first touch electrodes (311), the first bridge electrodes (312), and the second touch electrodes (322). The display pads (104) may have the same structure as the touch pads (304). For example, each display pad (104) may include a lower pad electrode and an upper pad electrode located on the lower pad electrode. The lower pad electrode of each display pad (104) may contain the same material as the lower pad electrode (304a) of each touch pad (304), and the upper pad electrode of each display pad (104) may contain the same material as the upper pad electrode (304b) of each touch pad (304). For example, the display pads (104) may be formed simultaneously with the touch pads (304).

[0085] The touch pads (304) may be electrically connected to the first touch line (310) and the second touch line (320) through touch routing lines (330). For example, the touch driving signal may be applied to the first touch line (310) through one of the touch pads (304) and one of the touch routing lines (330), and the charge charged by the touch driving signal may be discharged through the second touch line (320), one of the touch routing lines (330), and one of the touch pads (304).

[0086] The touch routing lines (330) may be formed using the forming process of the touch sensor (Cm). For example, each touch routing line (330) may have a stacked structure of a lower routing line (331) containing the same material as the second bridge electrodes (322) and an upper routing line (332) containing the same material as the first bridge electrodes (312). The upper routing line (332) of each touch routing line (330) may be electrically connected to the lower routing line (331) of the corresponding touch routing line (330). For example, the touch insulating film (350) may include routing contact holes that partially expose the lower routing line (331) of each touch routing line (330). The upper routing line (332) of each touch routing line (330) may come into direct contact with the lower routing line (331) of the corresponding touch routing line (330) through the routing contact holes. Accordingly, in a touch display device according to an embodiment of the present invention, the first touch line (310) and the second touch line (320) can be stably connected to the corresponding touch pad (304) by the touch routing lines (330). In addition, in a touch display device according to an embodiment of the present invention, the resistance of each touch routing line (330) can be reduced. Therefore, in a touch display device according to an embodiment of the present invention, signal delay caused by the touch routing lines (330) can be minimized.

[0087] The light-blocking pattern (410) may extend along the touch routing lines (330). For example, the first light-blocking pattern (411) may extend along the touch routing line (330) which is electrically connected to the first touch line (310), and the second light-blocking pattern (412) may extend along the touch routing line (330) which is electrically connected to the second touch line (320). The light-blocking pattern (410) may be located only on the touch routing lines (330). For example, the planar shape of the light-blocking pattern (410) between the display area (AA) and the pad area (PD) may be identical to the planar shape formed by the touch routing lines (330). Accordingly, in a touch display device according to an embodiment of the present invention, external light reflection between the display area (AA) and the pad area (PD) can be prevented by the light-blocking pattern (410).

[0088] The touch protective film (370) may cover the touch routing lines (330). The light-blocking pattern (410) may be electrically connected to the touch routing lines (330). For example, the first light-blocking pattern (411) and the second light-blocking pattern (412) may each penetrate a portion of the touch protective film (370) and be electrically connected to the corresponding touch routing line (330). Accordingly, in a touch display device according to an embodiment of the present invention, the resistance of each touch routing line (330) may be significantly reduced. Therefore, in a touch display device according to an embodiment of the present invention, signal delay caused by the touch routing lines (330) may be prevented.

[0089] The above device buffer film (111), the interlayer insulating film (112), the touch buffer film (200), the touch insulating film (350), the touch protective film (370), the upper protective film (390), and the device protective film (500) may extend onto the pad region (PD) of the device substrate (110). For example, the lower pad electrode (304a) of each touch pad (304) may be located on the interlayer insulating film (112), and the upper pad electrode (304b) of each touch pad (304) may pass through the touch buffer film (200) and the touch insulating film (350) to be electrically connected to the lower pad electrode (304a) of the corresponding touch pad (304). The touch protective film (370), the upper protective film (390), and the element protective film (500) can partially expose the upper pad electrode (304b) of each touch pad (304).

[0090] In the pad area (PD), first power pads (704) electrically connected to a first power voltage supply line (VSS) that supplies a negative power voltage to each pixel area (PA), and second power pads (804) connected to a first power voltage supply line (VDD) that supplies a positive power voltage to each pixel area (PA) may be located. The first power voltage supply line (VSS) may extend along the edge of the display area (AA). For example, the first power voltage supply line (VSS) may be located outside the touch routing lines (330). Accordingly, in a touch display device according to an embodiment of the present invention, noise caused by an external signal may be blocked by the first power voltage supply line (VSS). The second power voltage supply line (VDD) may extend parallel to the signal wiring electrically connected to the display pads (104).

[0091] Consequently, a touch display device according to an embodiment of the present invention includes a light-blocking pattern (410) located on a touch protective film (370) covering a touch sensor (Cm), wherein the light-blocking pattern (410) comprising a low-reflection metal may include a first light-blocking pattern (411) electrically connected to the first touch electrodes (311) and the first bridge electrodes (312) of the touch sensor (Cm), and a second light-blocking pattern (412) electrically connected to the second touch electrodes (321) of the touch sensor (Cm). Accordingly, in a touch display device according to an embodiment of the present invention, the resistance of the first touch line (310) and the second touch line (320) may be reduced by the light-blocking pattern (410). Accordingly, in a touch display device according to an embodiment of the present invention, external light reflection is reduced without reducing the area of ​​the light-emitting regions (BEA, GEA, REA), and the reliability of touch detection and the quality of the implemented image can be improved.

[0092] A touch display device according to an embodiment of the present invention is described as having the space between the first light-blocking pattern (411) and the second light-blocking pattern (412) filled by the upper protective film (390). However, as illustrated in FIGS. 6 and 7, a touch display device in another embodiment of the present invention may include a dummy pattern (410p) located between the first light-blocking pattern (411) and the second light-blocking pattern (412). The dummy pattern (410p) may include a material having a relatively low reflectivity. The dummy pattern (410p) may be formed using the formation process of the light-blocking pattern (410). For example, the dummy pattern (410p) may include the same material as the first light-blocking pattern (411) and the second light-blocking pattern (412). The dummy pattern (410p) may be formed simultaneously with the first light-blocking pattern (411) and the second light-blocking pattern (412). For example, the dummy pattern (410p) may be located on the same layer as the first light-blocking pattern (411) and the second light-blocking pattern (412). Accordingly, in a touch display device according to another embodiment of the present invention, light leakage caused by the gap (410p) between the first light-blocking pattern (411) and the second light-blocking pattern (412) can be prevented.

[0093] In a touch display device according to another embodiment of the present invention, the first power supply voltage line (VSS) may have a multilayer structure. For example, as shown in FIGS. 8 and 9, in a touch display device according to another embodiment of the present invention, the first power supply voltage line (VSS) may include a first lower supply line (431) and a first upper supply line (432). The first upper supply line (432) may be located on the first lower supply line (431). The first lower supply line (431) may be formed using the pixel driving circuit of each pixel area (PA) and the formation process of the light-emitting element (130). For example, the first lower supply line (431) may be formed simultaneously with the source electrode (124) and the drain electrode (125). The first lower supply line (431) may be located on the same layer as the source electrode (124) and the drain electrode (125). For example, the first lower supply line (431) may be located between the interlayer insulating film (112) and the touch buffer film (200). The first lower supply line (431) may contain the same material as the source electrode (124) and the drain electrode (125). The first upper supply line (432) may be formed simultaneously with the light-blocking pattern (410). For example, the first upper supply line (432) may contain the same material as the first light-blocking pattern (411) and the second light-blocking pattern (412). The first upper supply line (432) may be located on the same layer as the first light-blocking pattern (411) and the second light-blocking pattern (412). For example, the first upper supply line (432) may be located between the touch protective film (370) and the upper protective film (390).

[0094] The first upper supply line (432) may be electrically connected to the first lower supply line (431). For example, the first upper supply line (432) may extend parallel to the first lower supply line (431). Accordingly, in a touch display device according to another embodiment of the present invention, the touch sensor (Cm) may not be affected by external signals due to the first upper supply line (432). Therefore, in a touch display device according to another embodiment of the present invention, the reliability of touch detection by the touch sensor (Cm) may be improved. In addition, in a touch display device according to another embodiment of the present invention, the resistance of the first power supply voltage supply line (VSS) may be reduced. That is, in a touch display device according to another embodiment of the present invention, the first power supply voltage may be uniformly supplied to each pixel area (PA).

[0095] In a touch display device according to another embodiment of the present invention, a shorting bar (440) may be positioned between the touch routing lines (330) to electrically connect the second power supply voltage lines (VDD). For example, the shorting bar (440) may be formed simultaneously with the light-blocking pattern (410). The shorting bar (440) may include the same material as the first light-blocking pattern (411) and the second light-blocking pattern (412). The shorting bar (440) may be positioned on the same layer as the first light-blocking pattern (411) and the second light-blocking pattern (412). For example, the shorting bar (440) may be positioned between the touch protective film (370) and the upper protective film (390). Accordingly, in a touch display device according to another embodiment of the present invention, the second power supply voltage may be uniformly supplied to each pixel area (PA).
