For example, source electrode 250 may include metals such as aluminum (Al), titanium (Ti), copper (Cu), chromium (Cr), molybdenum (Mo), and tungsten (W). Source electrode 250 may be insulated from gate electrode 230 through interlayer insulating layer 240. For example, source electrode 250 may include a different material than gate electrode 230. Source electrode 250 may be electrically connected to the source region of semiconductor pattern 210. For example, gate insulating layer 220 and interlayer insulating layer 240 may include source contact holes that partially expose the source region of semiconductor pattern 210. Source electrode 250 may include a portion overlapping with the source region of semiconductor pattern 210. For example, source electrode 250 may be in direct contact with the source region of semiconductor pattern 210 in the source contact hole.

It should be noted that the structure of the thin-film transistor 200 shown in the accompanying drawings of this application is for illustrative purposes only, and the embodiments of this disclosure are not limited thereto. Furthermore, the thin-film transistor 200 may have other structures besides those shown in the accompanying drawings. Figure 3 Various other structures besides the one shown.

[0044] A first buffer layer 110 may be disposed between the device substrate 100 and the driving circuit. The first buffer layer 110 can prevent contamination caused by the device substrate 100 during the process of forming the thin-film transistor 200. For example, the upper surface of the device substrate 100 facing the thin-film transistor 200 may be completely covered by the first buffer layer 110. The first buffer layer 110 may include an insulating material. For example, the first buffer layer 110 may include inorganic insulating materials such as silicon oxide (SiO) and silicon nitride (SiN). The first buffer layer 110 may have a multilayer structure.

[0045] A light-blocking pattern 115 may be disposed between the first buffer layer 110 and each thin-film transistor 200. The light-blocking pattern 115 can prevent changes in the characteristics of each thin-film transistor 200 due to external light. For example, the light-blocking pattern 115 may include portions overlapping with the semiconductor pattern 210 of each thin-film transistor 200. The light-blocking pattern 115 may include a material that blocks or absorbs light. For example, the light-blocking pattern 115 may include metals such as aluminum (Al), silver (Ag), and copper (Cu). The light-blocking pattern 115 may have a multilayer structure. For example, the light-blocking pattern 115 may have a structure in which layers made of metal are disposed between layers made of transparent metal oxides such as ITO and IZO. Therefore, in the display panel DP of the transparent touch display device according to embodiments of the present disclosure, changes in the characteristics of each thin-film transistor 200 due to external light can be effectively prevented.

[0046] The light-blocking pattern 115 may be insulated from the semiconductor pattern 210 of each thin-film transistor 200. For example, a second buffer layer 120 may be disposed between the light-blocking pattern 115 and the semiconductor pattern 210 of each thin-film transistor 200. The second buffer layer 120 may extend beyond the light-blocking pattern 115. For example, the sides of the light-blocking pattern 115 may be covered by the second buffer layer 120. The second buffer layer 120 may be in direct contact with the first buffer layer 110 on the outside of the light-blocking pattern 115. The second buffer layer 120 may include an insulating material. For example, the second buffer layer 120 may include inorganic insulating materials such as silicon oxide (SiO) and silicon nitride (SiN). The second buffer layer 120 may include the same material as the first buffer layer 110.

[0047] The lower passivation layer 130 can be disposed on the drive circuit. The lower passivation layer 130 can prevent damage to the drive circuit due to external impacts and moisture. For example, the upper surface of each thin-film transistor 200 opposite to the device substrate 100 can be covered by the lower passivation layer 130. The lower passivation layer 130 may include an insulating material. For example, the lower passivation layer 130 may include inorganic insulating materials such as silicon oxide (SiO) and silicon nitride (SiN). The lower passivation layer 130 can be a single layer with a constant thickness.

[0048] The lower outer cover layer 140 may be disposed on the lower passivation layer 130. The lower outer cover layer 140 can eliminate thickness differences caused by the driving circuit. For example, thickness differences caused by the thin-film transistor 200 can be eliminated by the lower outer cover layer 140. The upper surface of the lower outer cover layer 140 opposite to the device substrate 100 may be a flat surface. The lower outer cover layer 140 may include an insulating material. The lower outer cover layer 140 may include the same or different material as the lower passivation layer 130. For example, the lower outer cover layer 140 may include an organic insulating material.

[0049] Pixel electrodes 310 may be disposed on the lower outer cover layer 140. Each pixel electrode 310 may be spaced apart from adjacent pixel electrodes 310. Each pixel electrode 310 may be electrically connected to a driving circuit in the driving circuitry. For example, the lower passivation layer 130 and the lower outer cover layer 140 may include electrode contact holes that partially expose the thin-film transistors 200 of each driving circuit. Each pixel electrode 310 may be electrically connected to a corresponding thin-film transistor 200 through one of the electrode contact holes. Pixel electrodes 310 may include conductive materials. Pixel electrodes 310 may include materials with high reflectivity. For example, pixel electrodes 310 may include metals such as aluminum (Al) and silver (Ag). Pixel electrodes 310 may have a multilayer structure. For example, each pixel electrode 310 may have a structure in which a reflective electrode made of metal is disposed between transparent electrodes made of transparent conductive materials such as ITO and IZO.

[0050] A dam insulating layer 160 may be disposed in the space between adjacent pixel electrodes 310. Each pixel electrode 310 may be insulated from its adjacent pixel electrode 310 by the dam insulating layer 160. For example, the dam insulating layer 160 may cover the edge of each pixel electrode 310. The dam insulating layer 160 may be disposed on the lower outer cover layer 140. The dam insulating layer 160 may extend beyond the pixel electrode 310. For example, the dam insulating layer 160 may be in direct contact with the lower outer cover layer 140 between the pixel electrodes 310. The dam insulating layer 160 may include an insulating material. For example, the dam insulating layer 160 may include an organic insulating material. The dam insulating layer 160 may include a material different from the lower outer cover layer 140.

[0051] The light-emitting layer 320 can be disposed on a portion of each pixel electrode 310 exposed by the insulating layer 160. The light-emitting layer 320 can generate light displaying a specific color. For example, a portion of each pixel electrode 310 exposed by the insulating layer 160 can be defined as a light-emitting region EA. The light-emitting layer 320 may include a light-emitting material layer (EML) comprising a light-emitting material. The light-emitting material may include organic materials, inorganic materials, or mixed materials. For example, the display panel DP of the transparent touch display device according to embodiments of the present disclosure may be an organic light-emitting display panel comprising an organic light-emitting material. Each light-emitting layer 320 may have a multilayer structure. For example, each light-emitting layer 320 may include at least one of a hole injection layer (HIL), a hole transport layer (HTL), an electron transport layer (ETL), and an electron injection layer (EIL). Therefore, in the display panel DP of the transparent touch display device according to embodiments of the present disclosure, the luminous efficiency of each light-emitting layer 320 can be increased.

[0052] The device substrate 100 may include a transmissive region TA disposed outside the light-emitting region EA defined by the insulating layer 160. External light can pass through the transmissive region TA of the device substrate 100. For example, when no image is displayed, the display panel DP of the transparent touch display device according to an embodiment of the present disclosure can be identified as transparent glass. The light-emitting region EA and the transmissive region TA may be arranged repeatedly in a first direction X. For example, in the display panel DP of the transparent touch display device according to an embodiment of the present disclosure, a pair of light-emitting regions EA and transmissive regions TA may be arranged repeatedly in the first direction X. Each transmissive region TA may have a larger size than each light-emitting region EA. For example, each transmissive region TA may extend in a second direction Y perpendicular to the first direction X. The light-emitting regions EA may be arranged side by side in the second direction Y. For example, in the display panel DP of the transparent touch display device according to an embodiment of the present disclosure, the arrangement of the light-emitting regions EA between adjacent transmissive regions TA may have a matrix shape in the first direction X and the second direction Y.

[0053] The first buffer layer 110, the second buffer layer 120, the lower passivation layer 130, the lower outer cover layer 140, the dam insulating layer 160, and the gate insulating layer 220 and interlayer insulating layer 240 of each thin-film transistor 200 can extend onto the transmissive region TA of the device substrate 100. The light-blocking pattern 115 and the conductive layer of each driving circuit can be disposed outside the transmissive region TA. For example, the semiconductor pattern 210, gate electrode 230, source electrode 250, and drain electrode 260 of each thin-film transistor 200 can be disposed outside the transmissive region TA. Therefore, in the display panel DP of the transparent touch display device according to an embodiment of the present disclosure, degradation of transmittance due to the light-blocking pattern 115 and the driving circuit can be prevented.

[0054] The upper electrode 330 may be disposed on the insulating layer 160 and the light-emitting layer 320. The upper electrode 330 may include a conductive material. The upper electrode 330 may include a material different from that of the pixel electrode 310. The upper electrode 330 may have a higher transmittance than each pixel electrode 310. For example, the upper electrode 330 may be a transparent electrode made of a transparent conductive material such as ITO and IZO. The upper electrode 330 may include a first electrode region 330a overlapping the light-emitting region EA and a second electrode region 330b overlapping the transmissive region TA.

[0055] Each light-emitting layer 320 can generate light with a brightness corresponding to the voltage difference between the corresponding pixel electrode 310 and the corresponding first electrode region 330a of the upper electrode 330. For example, the pixel electrode 310, the light-emitting layer 320, and the first electrode region 330a of the upper electrode 330 sequentially stacked on the lower outer cover layer 140 of each light-emitting region EA can constitute a light-emitting device 300. The pixel electrode 310 and the first electrode region 330a of the upper electrode 330 disposed on each light-emitting region EA can be used as the first electrode and the second electrode of the corresponding light-emitting device 300, respectively. Each driving circuit can provide a driving current to one of the light-emitting devices 300. For example, the pixel electrode 310 of each light-emitting device 300 can be electrically connected to the drain electrode 260 of the corresponding thin-film transistor 200 through one of the electrode contact holes. The light generated from the light-emitting layer 320 of each light-emitting region EA can be emitted to the outside through the corresponding first electrode region 330a of the upper electrode 330. For example, in the display panel DP of the transparent touch display device according to an embodiment of the present disclosure, the image of the light-emitting device 300 can be implemented on the upper electrode 330.

[0056] The same voltage can be applied to the first electrode region 330a of each of the light-emitting devices 300 disposed between adjacent transmission regions TA. For example, the first electrode regions 330a of the light-emitting devices 300 disposed between adjacent transmission regions TA can be electrically connected to each other. The first electrode regions 330a of the light-emitting devices 300 disposed between adjacent transmission regions TA can include the same material. For example, each first electrode region 330a of the upper electrode 330 can extend in the first direction X and the second direction Y between the transmission regions TA. The first electrode regions 330a of the light-emitting devices 300 disposed between adjacent transmission regions TA can be in contact with each other. The light-emitting layer 320 of each light-emitting device 300 can extend along the corresponding first electrode region 330a of the light-emitting device 300. For example, the light-emitting layer 320 of the light-emitting devices 300 disposed between adjacent transmission regions TA can include the same material. The light-emitting devices 300 disposed between adjacent transmission regions TA can emit light of the same wavelength.

[0057] The second electrode region 330b of the upper electrode 330 may be spaced apart from the first electrode region 330a of the upper electrode 330.

For example, a separation partition 175 may be disposed on the insulating layer 160 between the first electrode region 330a and the second electrode region 330b of the upper electrode 330. The separation partition 175 may include a side portion having an inverted conical shape. Therefore, in the display panel DP of the transparent touch display device according to an embodiment of the present disclosure, the first electrode region 330a and the second electrode region 330b of the upper electrode 330 may be formed simultaneously without additional patterning processes. For example, an electrode pattern 330p comprising the same material as the first electrode region 330a and the second electrode region 330b may be disposed on the upper surface of the separation partition 175 opposite to the device substrate 100. The second electrode region 330b of the upper electrode 330 may comprise the same material as the first electrode region 330a of the upper electrode.

[0064] Each second electrode region 330b of the upper electrode 330 can be electrically connected to one of the second link lines 520. Therefore, in the display panel DP of the transparent touch display device according to an embodiment of the present disclosure, the second electrode regions 330b of the upper electrode 330 can function differently from the first electrode regions 330a of the upper electrode 330. Each second link line 520 can be electrically connected to the corresponding second electrode region 330b of the upper electrode 330 through at least one of the conductive layers disposed between the first buffer layer 110 and the dam insulating layer 160.

For example, in the display panel DP of the transparent touch display device according to embodiments of the present disclosure, the touch electrode for sensing touches from users and / or tools can be formed simultaneously with the light-emitting device 300. Therefore, in the display panel DP of the transparent touch display device according to embodiments of the present disclosure, the process can be simplified, and misalignment of the light-emitting device 300 and the second electrode region 330b of the upper electrode used as a touch electrode can be prevented.

[0067] Furthermore, in the display panel DP of the transparent touch display device according to the embodiments of the present disclosure, the first electrode region 330a, which serves as the upper electrode 330 of the second electrode of each light-emitting device 300, can be disposed on the light-emitting region EA of the device substrate 100, and the second electrode region 330b, which serves as the upper electrode 330 of the touch electrode, can be disposed on the transmissive region TA of the device substrate 100.

The thickness difference caused by the light-emitting device 300 and the separation partition 175 can be eliminated by the second encapsulation layer 420. For example, the upper surface of the package element 400 opposite to the device substrate 100 can be a flat surface. The sides of each separator 175 having an inverted cone can be surrounded by the package element 400.

[0069] The black matrix 610 and color filter 620 can be disposed side-by-side on the encapsulation element 400. Each color filter 620 can overlap with one of the light-emitting regions EA. The color filter 620 on each light-emitting region EA can include a different material than the color filters on adjacent light-emitting regions EA. Therefore, in the display panel DP of the transparent touch display device according to an embodiment of the present disclosure, the light-emitting regions EA can display various colors. The black matrix 610 can be disposed side-by-side with the color filter 620 on the encapsulation element 400. The black matrix 610 can be disposed between the color filters 620. For example, the insulating layer 160 between the light-emitting devices 300 can overlap with the black matrix 610.

Therefore, in the display panel DP of the transparent touch display device according to the embodiments of the present disclosure, the reduction in transmittance caused by the black matrix 610 and the color filter 620 can be prevented.

[0070] An insulating layer 650 may be disposed on the black matrix 610 and the color filter 620.

Therefore, in the transparent touch display device according to the embodiments of the present disclosure, the process can be simplified, misalignment of the light-emitting devices 300 and touch electrodes can be prevented, and the reliability of touch sensing can be improved without degrading the image.

[0074] Furthermore, in the transparent touch display device according to the embodiments of the present disclosure, a first link 550 for applying voltage to the first electrode region 330a of each light-emitting device 300 and a second link 520 respectively connected to the second electrode region 330b can be disposed between the device substrate 100 and the lower outer cover layer 140. Therefore, in the transparent touch display device according to the embodiments of the present disclosure, the process for forming the first link 550 and the second link 520 can be simplified, and the area occupied by the first link 550 and the second link 520 can be minimized. Therefore, in the transparent touch display device according to the embodiments of the present disclosure, the dimensions of the light-emitting region EA and the transmissive region TA can be maximized.

[0075] The transparent touch display device according to an embodiment of the present disclosure is described as having each of the first electrode region 330a and the second electrode region 330b in single-point contact with corresponding upper intermediate links 522 and 552. However, in another embodiment of the transparent touch display device according to the present disclosure, the first upper contact hole and the second upper contact hole may extend along the separation partition 175. For example, in another embodiment of the transparent touch display device according to the present disclosure, each first upper contact hole may extend along the separation partition 175 in a second direction between the light-emitting region EA and the transmissive region TA, and each second upper contact hole may surround the corresponding second electrode region 330b along the separation partition 175.

[0076] The transparent touch display device according to an embodiment of the present disclosure is described as having the first link 550 and the second link 520 formed simultaneously with the light-blocking pattern 115. However, in another embodiment of the transparent touch display device according to the present disclosure, the first link 550 and the second link 520 may be formed simultaneously with one of the conductive layers disposed between the first buffer layer 110 and the dam insulating layer 160. Furthermore, the transparent touch display device according to another embodiment of the present disclosure may include additional conductive layers for the first link 550 and the second link 520.

Each connecting electrode 510 may penetrate the lower outer cover layer 140 to connect to the drain electrode 260 of one of the thin-film transistors 200. For example, the pixel electrode 310 of each light-emitting device 300 may be connected to the corresponding thin-film transistor 200 via one of the connecting electrodes 510. Each connecting electrode 510 may include a portion overlapping with the drain electrode 260 of one of the thin-film transistors 200 and a portion overlapping with the pixel electrode 310 of one of the light-emitting devices 300. For example, the pixel electrode 310 of each light-emitting device 300 may be connected to the corresponding connecting electrode 510 via penetrating the upper outer cover layer 150.

[0078] The first link 550 and the second link 520 may be spaced apart from the connecting electrode 510. The first link 550 and the second link 520 may comprise the same material as the connecting electrode 510. Therefore, in a transparent touch display device according to another embodiment of the present disclosure, the resistance between the first link 550 and the second link 520 can be minimized. Therefore, in a transparent touch display device according to another embodiment of the present disclosure, the reliability of touch sensing can be improved.

[0079] The transparent touch display device according to an embodiment of the present disclosure is described as sensing the touch of a user and / or tool using a self-capacitance method by using a second electrode region 330b having a block shape on each transmissive region TA. However, the transparent touch display device according to another embodiment of the present disclosure can sense the touch of a user and / or tool using a mutual capacitance method. For example, in the transparent touch display device according to another embodiment of the present disclosure, the upper electrode 330 may include a first electrode region 330a connected to a first link line 550, a second electrode region 330b connected to a second link line 520, and a third electrode region 330c connected to a third link line 522, wherein the first electrode region 330a, the second electrode region 330b, and the third electrode region 330c, which are spaced apart from each other in a first direction X, may extend parallel to each other in a second direction Y perpendicular to the first direction X, such as... Figure 5 As shown. Each first electrode region 330a may overlap with the light-emitting region of the device substrate. The second electrode region 330b and the third electrode region 330c may be disposed on the transmissive region of the device substrate. For example, each first electrode region 330a may be disposed between one of the second electrode regions 330b and one of the third electrode regions 330c.

The third link line 522 may include the same material as the light-blocking pattern. The third link line 522 may extend in the second direction Y. For example, the third link line 522 may be spaced apart from the first link line 550, the second link line 521, and the light-blocking pattern 115.

[0080] The second electrode region 330b may be insulated from the third link line 522. The third electrode region 330c may be insulated from the second link line 521. The signal applied to the third link line 522 may be different from the signal applied to the second link line 521. For example, a touch driving signal Tx may be applied to the second electrode region 330b, and a touch sensing signal Rx may be applied to the third electrode region 330c. For example, in a transparent touch display device according to another embodiment of the present disclosure, the electrode regions 330b and 330c of the upper electrode 330, which serve as touch electrodes on the transmission region TA, may be divided into a first group for applying the touch driving signal Tx and a second group for applying the touch sensing signal Rx. Therefore, in a transparent touch display device according to another embodiment of the present disclosure, the touch of a user and / or tool may be sensed by the second electrode region 330b connected to the second link line 521 and the third electrode region 330c connected to the third link line 522. Therefore, in a transparent touch display device according to an embodiment of the present disclosure, the degree of freedom of the touch sensing method may be increased.

[0081] The transparent touch display device according to an embodiment of the present disclosure is described as having each of the link lines 520 and 550 connected to corresponding electrode regions 330a and 330b via intermediate links 521, 522, 551, and 552. However, in another embodiment of the transparent touch display device according to the present disclosure, each of the electrode regions 330a and 330b may be in direct contact with the corresponding link lines 520 and 550 below the separation partition 175, such as... Figure 6 and Figure 7 As shown. Therefore, in a transparent touch display device according to another embodiment of the present disclosure, process efficiency can be effectively improved. It should be noted that, although Figures 3 to 7 It has been shown that the first link 550 and the second link 520 are disposed between the first buffer layer 110 and the second buffer layer 120, or between the lower outer cover layer 140 and the upper outer cover layer 150. However, embodiments of this disclosure are not limited thereto, and the first link 550 and the second link 520 may be disposed at any other location between the device substrate 100 and the upper outer cover layer 150, for example, between the interlayer insulating layer 240 and the lower passivation layer 130. For another example, the first link 550 and the second link 520 may be disposed at different layers between the device substrate 100 and the upper outer cover layer 150.

[0082] A transparent touch display device according to an embodiment of the present disclosure is described in which the ends of each electrode region 330a and 330b separated by the separating partition 175 can be connected to corresponding upper intermediate links 522 and 552. However, in a transparent touch display device according to another embodiment of the present disclosure, each of the electrode regions 330a and 330b can be connected to the corresponding upper intermediate links 522 and 552 through one of the intermediate contact holes disposed outside the separating partition 175. For example, in a transparent touch display device according to another embodiment of the present disclosure, each first electrode region 330a of the upper electrode 330 may include a protruding region 330ap extending in the first direction X, and the insulating layer 160 may include a first intermediate contact hole 161h overlapping the protruding region 330ap of each first electrode region 330a, such as...

The protruding region 330ap of each first electrode region 330a may include a portion overlapping with the corresponding first upper intermediate link 552. For example, the protruding region 330ap of each first electrode region 330a can be connected to the first upper intermediate link 552 through one of the first intermediate contact holes 161h. Therefore, in a transparent touch display device according to another embodiment of the present disclosure, the degree of freedom in the connection method between each first electrode region 330a and the corresponding first link line 550 can be increased.

[0083] The protruding region 330ap of each first electrode region 330a may include a portion overlapping with one of the transmission regions of the device substrate 100. For example, the protruding region 330ap of each first electrode region 330a may be disposed between the second electrode regions 330b disposed on each transmission region. Each second electrode region 330b may include a recessed region for the location of the protruding region 330ap.

[0084] The insulating layer 160 may include a second intermediate contact hole 162h for connecting each second electrode region 330b to one of the second upper intermediate links 522. The second intermediate contact hole 162h may be arranged side by side with the first intermediate contact hole 161h in the second direction Y. Therefore, in a transparent touch display device according to another embodiment of the present disclosure, the size of the light-emitting area and / or the transmissive area reduced by the first intermediate contact hole 161h and the second intermediate contact hole 162h can be minimized. Therefore, in a transparent touch display device according to another embodiment of the present disclosure, the size of the light-emitting area and the light-emitting area can be maximized.

[0085] As a result, the transparent touch display device according to the embodiments of the present disclosure may include a light-emitting device on a light-emitting area of ​​a device substrate and a touch electrode on a transparent / transmissive area of ​​the device substrate.
