[0046] The light-blocking pattern (115) may be insulated from the semiconductor pattern (210) of each thin-film transistor (200).

The bank insulating film (160) may include an insulating material. For example, the bank insulating film (160) may include an organic insulating material. The bank insulating film (160) may include a material different from the lower overcoat layer (140).

[0051] A light-emitting layer (320) may be located on a portion of each pixel electrode (310) exposed by the bank insulating film (160). The light-emitting layers (320) may generate light that exhibits a specific color. For example, a portion of each pixel electrode (310) exposed by the bank insulating film (160) may be defined as a light-emitting region (EA). The light-emitting layers (320) 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, the display panel (DP) of the transparent touch display device according to an embodiment of the present invention may be an organic light-emitting display panel containing an organic light-emitting material.

For example, each light-emitting layer (320) may further 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). Accordingly, the light-emitting efficiency of each light-emitting layer (320) in the display panel (DP) of the transparent touch display device according to an embodiment of the present invention may be improved.

[0052] The above-described device substrate (100) may include transparent regions (TA) located outside the light-emitting regions (EA) defined by the bank insulating film (160). External light may pass through the transparent regions (TA) of the device substrate (100). For example, the display panel (DP) of the transparent touch display device according to an embodiment of the present invention may be perceived as transparent glass when no image is displayed. The light-emitting regions (EA) and the transparent regions (TA) may be repeatedly arranged 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 invention, two light-emitting regions (EA) and transparent regions (TA) may be repeatedly arranged in the first direction (X). Each transparent region (TA) may have a larger area than a single light-emitting region (EA). For example, each transparent region (TA) may extend in a second direction (Y) perpendicular to the first direction (X). The light-emitting regions (EA) may be positioned 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 invention, the arrangement of the light-emitting regions (EA) between two adjacent transparent regions (TA) may have a matrix form in the first direction (X) and the second direction (Y).

[0053] The first buffer layer (110), the second buffer layer (120), the lower protective layer (130), the lower overcoat layer (140), the bank insulating layer (160), and the gate insulating layer (220) and the interlayer insulating layer (240) of each thin-film transistor (200) may extend over the transparent regions (TA) of the device substrate (100). The light-blocking pattern (115) and the conductive layer of each driving circuit may be located outside the transparent regions (TA). For example, the semiconductor pattern (210), the gate electrode (230), the source electrode (250), and the drain electrode (260) of each thin-film transistor (200) may be located outside the transparent regions (TA). Accordingly, in the display panel (DP) of the transparent touch display device according to an embodiment of the present invention, a decrease in transmittance caused by the light-blocking pattern (115) and the driving circuits can be prevented.

[0054] An upper electrode (330) may be positioned on the bank insulating film (160) and the light-emitting layers (320). The upper electrode (330) may include a conductive material. The upper electrode (330) may include a material different from that of the pixel electrodes (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 first electrode regions (330a) that overlap with the light-emitting regions (EA) and second electrode regions (330b) that overlap with the transmission regions (TA).

[0055] Each light-emitting layer (320) can generate light of 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), which are stacked sequentially on the lower overcoat layer (140) of each light-emitting region (EA), can constitute a light-emitting element (300). The pixel electrode (310) and the first electrode region (330a) of the upper electrode (330) located on each light-emitting region (EA) can function as the first electrode and the second electrode of the corresponding light-emitting element (300), respectively. Each light-emitting element (300) can receive a driving current from one of the driving circuits. For example, the pixel electrode (310) of each light-emitting element (300) may be electrically connected to the drain electrode (260) of the corresponding thin-film transistor (200) through one of the electrode contact holes. Light generated in the light-emitting layer (320) of each light-emitting region (EA) may 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 invention, an image by the light-emitting elements (300) may be implemented on the upper electrode (330).

[0056] The same voltage may be applied to the first electrode region (330a) of each of the light-emitting elements (300) located between adjacent transmission regions (TA). For example, the first electrode regions (330a) of the light-emitting elements (300) located between adjacent transmission regions (TA) may be electrically connected to each other. The first electrode regions (330a) of the light-emitting elements (300) located between adjacent transmission regions (TA) may contain the same material.

The first electrode regions (330a) of the light-emitting elements (300) located between two transmission regions (TA) adjacent in the first direction (X) may be connected to each other. The light-emitting layer (320) of each light-emitting element (300) may extend along the first electrode region (330a) of the light-emitting element (300).

[0064] Each second electrode region (330b) of the upper electrode (330) may be electrically connected to one of the second link wirings (520). Accordingly, in the display panel (DP) of the transparent touch display device according to an embodiment of the present invention, the second regions (330b) of the upper electrode (330) may perform a different function from the first electrode regions (330a) of the upper electrode (330).

The black matrix (610) and the color filters (620) may be located outside the transmission regions (TA). Therefore, in the display panel (DP) of the transparent touch display device according to an embodiment of the present invention, a decrease in transmittance caused by the black matrix (610) and the color filters (620) can be prevented.

[0080] The second electrode regions (330b) may be insulated from the third link wiring (522). The third electrode regions (330c) may be insulated from the second link wiring (521). The third link wiring (522) may transmit a different signal than the second link wiring (521). For example, a touch driving signal (Tx) may be applied to the second electrode regions (330b), and a touch sensing signal (Rx) may be applied to the third electrode regions (330c). That is, in a transparent touch display device according to another embodiment of the present invention, the electrode regions (330b, 330c) of the upper electrode (330), which is located on the transparent regions (TA) and functions as a touch electrode, may be separated into a first group to which a touch driving signal (Tx) is applied and a second group to which a touch sensing signal (Rx) is applied.

Accordingly, process efficiency can be effectively improved in a transparent touch display device according to another embodiment of the present invention.

[0082] A transparent touch display device according to an embodiment of the present invention is described such that one end of each electrode region (330a, 330b) separated by a separating partition (175) is connected to the corresponding upper intermediate link (522, 552). However, in a transparent touch display device according to another embodiment of the present invention, each electrode region (330a, 330b) may be connected to the corresponding upper intermediate link (522, 552) through one of the intermediate contact holes located outside the separating partition (175). For example, as illustrated in FIG. 8 to 10, in a transparent touch display device according to another embodiment of the present invention, each first electrode region (330a) of the upper electrode (330) includes a protruding region (330ap) extending in a first direction (X), and the bank insulating film (160) may include first intermediate contact holes (161h) that overlap with the protruding region (330ap) of each first electrode region (330a). Each first intermediate contact hole (161h) may partially expose one of the first upper intermediate links (552). The protruding region (330ap) of each first electrode region (330a) may include a region that overlaps with the corresponding first upper intermediate link (552). For example, the protruding area (330ap) of each first electrode area (330a) may be connected to the corresponding first upper intermediate link (552) through one of the first intermediate contact holes (161h). Accordingly, in a transparent touch display device according to another embodiment of the present invention, the degree of freedom regarding the connection method between each first electrode area (330a) and the corresponding first link wiring (550) may be improved.

[0083] The protruding region (330ap) of each first electrode region (330a) may include a region that overlaps with one of the transparent regions of the device substrate (100). For example, the protruding region (330ap) of each first electrode region (330a) may be located between the second electrode regions (330b) located on each transparent region. Each second electrode region (330b) may include a recess region for the location of the protruding region (330ap).

[0084] The bank insulating film (160) may include second intermediate contact holes (162h) for connecting each second electrode region (330b) to one of the second upper intermediate links (522). The second intermediate contact holes (162h) may be positioned parallel to the first intermediate contact holes (161h) in the second direction (Y). Accordingly, in a transparent touch display device according to another embodiment of the present invention, the area of ​​the light-emitting regions and / or the transparent regions reduced by the first intermediate contact holes (161h) and the second intermediate contact holes (162h) may be minimized. Thus, in a transparent touch display device according to another embodiment of the present invention, the area of ​​the light-emitting regions and the transparent regions may be maximized.
