[0052] Exemplary embodiments of the inventive concept will be described more fully hereinafter with reference to the accompanying drawings. Throughout the drawings, like reference numerals may indicate like elements.

[0053] It will be understood that when a component such as a film, a region, a layer, or an element is referred to as being "on," "connected to," "coupled to," or "adjacent to" another component, the component may be directly on, connected to, coupled to, or adjacent to the other component, or intervening components may be present. It will also be understood that when a component is referred to as being "between" two components, the component may be the only component between the two components, or one or more intervening components may also be present. It will also be understood that when a component is referred to as "covering" another component, the component may be the only component covering the other component, or one or more intervening components may also cover the other component. Other words used to describe the relationship between elements may be interpreted in a similar manner.

[0054] It will also be understood that, unless the context clearly indicates otherwise, the description of a feature or aspect in each exemplary embodiment can be used for other similar features or aspects in other exemplary embodiments.

[0055] As used herein, unless the context clearly indicates otherwise, the singular forms "a", "an", and "the" are also intended to include the plural forms.

[0056] For ease of description, spatial relative terms such as "under", "below", "lower", "beneath", "above", "upper", etc. may be used herein to describe the relationship of one element or feature to another (additional) element or feature as shown in the figures. It will be understood that the spatial relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, an element described as "under", "below", or "beneath" another element or feature will then be oriented "above" the other element or feature. Thus, the exemplary terms "under" and "beneath" can include both an above and a below orientation.

[0057] It will be understood that the terms "first", "second", "third", etc. are used herein to distinguish one element from another, and the elements are not limited by these terms. Thus, a "first" element in an exemplary embodiment can be described as a "second" element in another exemplary embodiment.

[0058] Here, when a value is described as being approximately the same as or approximately equal to another value, it will be understood that the values are equal to each other within the measurement error, or if measurably unequal, then as would be understood by one of ordinary skill in the art, the values are close enough in value to be functionally equal to each other. It will also be understood that when two components or directions are described as extending substantially parallel to each other or substantially perpendicular to each other, the two components or directions extend precisely parallel to each other or precisely perpendicular to each other, or as would be understood by one of ordinary skill in the art, the two components or directions (e.g., within the measurement error) extend approximately parallel to each other or approximately perpendicular to each other. Other uses of the terms "substantially" and "approximately" should be interpreted in a similar manner.

[0059] Figure 1 is a perspective view of a display device according to an exemplary embodiment of the inventive concept. Figure 2 is Figure 1 a plan view of the display device of

[0060] Referring to Figure 1 andFigure 2 The display device 10 can be used in portable electronic devices such as mobile phones, smart phones, tablet personal computers (PCs), mobile communication terminals, electronic notepads, e-book readers, portable multimedia players (PMPs), navigation devices, or ultra-mobile PCs (UMPCs). The display device 10 can also be used in the display units of, for example, televisions (TVs), notebook computers, monitors, billboards, or Internet of Things (IoT) devices. The display device 10 can also be used in wearable devices such as smart watches, watch phones, display devices such as glasses, or head-mounted displays (HMDs). The display device 10 can also be used in, for example, the instrument panel of a vehicle, the center instrument panel, or the center information display (CID), the in-vehicle mirror display of a replaceable side mirror of a vehicle, or the entertainment display provided behind the front seats of a vehicle.

[0061] The first direction (or X-axis direction) can be a direction that is substantially parallel to the short side of the display device 10 in a plan view, for example, the horizontal direction of the display device 10. The second direction (or Y-axis direction) can be a direction that is substantially parallel to the long side of the display device 10 in a plan view, for example, the vertical direction of the display device 10. The third direction (or Z-axis direction) can be the thickness direction of the display device 10 that intersects the first direction and the second direction.

[0062] The display device 10 can include a display panel 300. As Figure 1 and Figure 2 shown, the display panel 300 can include a frontward portion FS, a first side portion SS1, a second side portion SS2, a third side portion SS3, a fourth side portion SS4, a first corner portion CS1 connecting the first side portion SS1 and the second side portion SS2, a second corner portion CS2 connecting the second side portion SS2 and the third side portion SS3, a third corner portion CS3 connecting the third side portion SS3 and the fourth side portion SS4, and a fourth corner portion CS4 connecting the first side portion SS1 and the fourth side portion SS4.

[0063] The display panel 300 can include a flexible substrate SUB that is bendable, foldable, or rollable (see Figure 4 ). For example, the substrate SUB can include polyethersulfone (PES), polyacrylate (PA), polyarylate (PAR), polyetherimide (PEI), polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polyphenylene sulfide (PPS), polyallylate, polyimide (PI), polycarbonate (PC), triacetyl cellulose (TAC), cellulose acetate propionate (CAP), or a combination thereof. Optionally, the substrate SUB can include a metal material. The substrate SUB can be partially flexible or completely flexible.

[0064] In a plan view, the front portion FS may have a rectangular shape having a short side extending in a first direction (or X-axis direction) and a long side extending in a second direction (or Y-axis direction). In this case, the short side of the front portion FS may be relatively shorter than the long side of the front portion FS. However, the inventive concept is not limited thereto. For example, according to an exemplary embodiment, the front portion FS may have various other shapes such as another polygonal shape, a circular shape, or an oval shape in the plan view. Figure 1 and Figure 2 It is shown that the front portion FS is flat. However, the inventive concept is not limited thereto. For example, according to an exemplary embodiment, the front portion FS may be curved.

[0065] The first side portion SS1 may extend from the first side of the front portion FS. The first side portion SS1 may be curved along a first bending line ( Figure 3 BL1) on the first side of the front portion FS and may have a first curvature. As Figure 1 and Figure 2 shown, the first side of the front portion FS may be the left side of the front portion FS.

[0066] The second side portion SS2 may extend from the second side of the front portion FS. The second side portion SS2 may be curved along a second bending line ( Figure 3 BL2) on the second side of the front portion FS and may have a second curvature. The second curvature may be different from the first curvature, but the inventive concept is not limited thereto. As Figure 1 and Figure 2 shown, the second side of the front portion FS may be the lower side of the front portion FS.

[0067] The third side portion SS3 may extend from the third side of the front portion FS. The third side portion SS3 may be curved along a third bending line ( Figure 3 BL3) on the third side of the front portion FS and may have a third curvature. The third curvature may be the same as the first curvature, but the inventive concept is not limited thereto. As Figure 1 and Figure 2 shown, the third side of the front portion FS may be the right side of the front portion FS.

[0068] The fourth side portion SS4 may extend from the fourth side of the front portion FS. The fourth side portion SS4 may be curved along a fourth bending line ( Figure 3 BL4) on the fourth side of the front portion FS and may have a fourth curvature. The fourth curvature may be the same as the second curvature, but the inventive concept is not limited thereto. As Figure 1 and Figure 2As shown, the fourth side of the front portion FS may be the upper side of the front portion FS.

[0069] The first corner portion CS1 may be disposed between the first side portion SS1 and the second side portion SS2. For example, the first corner portion CS1 may be adjacent to the lower side of the first side portion SS1 and the left side of the second side portion SS2. The first corner portion CS1 may be a bi-curved region curved with a first curvature of the first side portion SS1 and a second curvature of the second side portion SS2. Thus, by the bending forces from the first curvature of the first side portion SS1 and the second curvature of the second side portion SS2, strain may be applied to the first corner portion CS1.

[0070] The second corner portion CS2 may be disposed between the second side portion SS2 and the third side portion SS3. For example, the second corner portion CS2 may be adjacent to the right side of the second side portion SS2 and the lower side of the third side portion SS3. The second corner portion CS2 may be a bi-curved region curved with a second curvature of the second side portion SS2 and a third curvature of the third side portion SS3. Thus, by the bending forces from the second curvature of the second side portion SS2 and the third curvature of the third side portion SS3, strain may be applied to the second corner portion CS2.

[0071] The third corner portion CS3 may be disposed between the third side portion SS3 and the fourth side portion SS4. For example, the third corner portion CS3 may be adjacent to the upper side of the third side portion SS3 and the right side of the fourth side portion SS4. The third corner portion CS3 may be a bi-curved region curved with a third curvature of the third side portion SS3 and a fourth curvature of the fourth side portion SS4. Thus, by the bending forces from the third curvature of the third side portion SS3 and the fourth curvature of the fourth side portion SS4, strain may be applied to the third corner portion CS3.

[0072] The fourth corner portion CS4 may be disposed between the first side portion SS1 and the fourth side portion SS4. For example, the fourth corner portion CS4 may be adjacent to the upper side of the first side portion SS1 and the left side of the fourth side portion SS4. The fourth corner portion CS4 may be a bi-curved region curved with a first curvature of the first side portion SS1 and a fourth curvature of the fourth side portion SS4. Thus, by the bending forces from the first curvature of the first side portion SS1 and the fourth curvature of the fourth side portion SS4, strain may be applied to the fourth corner portion CS4.

[0073] Each of the first corner portion CS1, the second corner portion CS2, the third corner portion CS3, and the fourth corner portion CS4 may include a cutout portion defined by a cutout as shown in Figure 6A or may include an island portion defined by a cutout as shown in Figure 24 ​

[0074] Figure 3 is Figure 1 an exploded view of a display device.

[0075] Referring to Figure 3 , the display panel 300 may further include a bending portion BA and a pad (or referred to as "pad" or "landing pad") portion PA. For example, the display panel 300 may include a first display area DA1, a second display area DA2, and a third display area DA3, a first non-display area NDA1 and a second non-display area NDA2, a bending portion BA, and a pad portion PA.

[0076] The first display area DA1, the second display area DA2, and the third display area DA3 refer to areas that include pixels or emission regions and thus display images. The first non-display area NDA1 and the second non-display area NDA2 refer to areas that do not include pixels or emission regions and thus do not display images. Signal lines or panel-embedded driving circuits for driving the pixels or emission regions may be provided in the first non-display area NDA1 and the second non-display area NDA2. The first non-display area NDA1 and the second non-display area NDA2 may be collectively referred to as the non-display area NDA.

[0077] The first display area DA1, which is the main display area of the display panel 300, may include a frontward portion FS, a part of the first side portion SS1, a part of the second side portion SS2, a part of the third side portion SS3, and a part of the fourth side portion SS4. Here, the part of the first side portion SS1 refers to the part of the first side portion SS1 extending from the first side of the frontward portion FS, the part of the second side portion SS2 refers to the part of the second side portion SS2 extending from the second side of the frontward portion FS, the part of the third side portion SS3 refers to the part of the third side portion SS3 extending from the third side of the frontward portion FS, and the part of the fourth side portion SS4 refers to the part of the fourth side portion SS4 extending from the fourth side of the frontward portion FS. The corners of the first display area DA1 may be formed to be circular with a predetermined curvature.

[0078] The second display area DA2 may be an auxiliary display area that assists the main display area. The resolution of the second display area DA2 may be different from the resolution of the first display area DA1. For example, the resolution of the second display area DA2 may be lower than the resolution of the first display area DA1. That is, the number of second emission areas per unit area of the second display area DA2 may be smaller than the number of first emission areas per unit area of the first display area DA1. However, the inventive concept is not limited thereto. For example, according to an exemplary embodiment, the resolution of the second display area DA2 may be substantially the same as the resolution of the first display area DA1.

[0079] The second display area DA2 may be disposed outside one corner of the first display area DA1. At least a part of the second display area DA2 may be disposed in at least one of the first corner portion CS1, the second corner portion CS2, the third corner portion CS3, and the fourth corner portion CS4. In addition, at least a part of the second display area DA2 may be disposed in the front portion FS. In addition, at least a part of the second display area DA2 may be disposed in at least two of the first side portion SS1, the second side portion SS2, the third side portion SS3, and the fourth side portion SS4.

[0080] For example, at least a part of the second display area DA2 outside the lower left corner of the first display area DA1 may be disposed in the front portion FS, the first corner portion CS1, the first side portion SS1, and the second side portion SS2. At least a part of the second display area DA2 outside the lower right corner of the first display area DA1 may be disposed in the front portion FS, the second corner portion CS2, the second side portion SS2, and the third side portion SS3. At least a part of the second display area DA2 outside the upper right corner of the first display area DA1 may be disposed in the front portion FS, the third corner portion CS3, the third side portion SS3, and the fourth side portion SS4. At least a part of the second display area DA2 outside the upper left corner of the first display area DA1 may be disposed in the front portion FS, the fourth corner portion CS4, the first side portion SS1, and the fourth side portion SS4.

[0081] The third display area DA3 may be an auxiliary display area that assists the main display area. The resolution of the third display area DA3 may be different from the resolution of the first display area DA1. For example, the resolution of the third display area DA3 may be lower than the resolution of the first display area DA1. That is, the number of third emission areas per unit area of the third display area DA3 may be smaller than the number of first emission areas per unit area of the first display area DA1. However, the inventive concept is not limited thereto. For example, according to an exemplary embodiment, the resolution of the third display area DA3 may be substantially the same as the resolution of the first display area DA1.

[0082] In an exemplary embodiment, the resolution of each of the first display area DA1, the second display area DA2, and the third display area DA3 is different from each other. For example, in an exemplary embodiment, the resolution of the second display area DA2 is lower than the resolution of the first display area DA1, and the resolution of the third display area DA3 is lower than the resolution of the second display area DA2.

[0083] The third display area DA3 may be disposed on the outside of the second display area DA2. Accordingly, the second display area DA2 may be disposed between the first display area DA1 and the third display area DA3. At least a part of the third display area DA3 may be disposed in at least one of the first corner portion CS1, the second corner portion CS2, the third corner portion CS3, and the fourth corner portion CS4. In addition, at least a part of the third display area DA3 may be disposed in at least two of the first side portion SS1, the second side portion SS2, the third side portion SS3, and the fourth side portion SS4.

[0084] For example, at least a part of the third display area DA3 that is outside the lower left corner of the first display area DA1 may be disposed in the first corner portion CS1, the first side portion SS1, and the second side portion SS2, at least a part of the third display area DA3 that is outside the lower right corner of the first display area DA1 may be disposed in the second corner portion CS2, the second side portion SS2, and the third side portion SS3, at least a part of the third display area DA3 that is outside the upper right corner of the first display area DA1 may be disposed in the third corner portion CS3, the third side portion SS3, and the fourth side portion SS4, and at least a part of the third display area DA3 that is outside the upper left corner of the first display area DA1 may be disposed in the fourth corner portion CS4, the first side portion SS1, and the fourth side portion SS4.

[0085] The first non-display area NDA1 may include a part of the first side portion SS1, a part of the second side portion SS2, a part of the third side portion SS3, and a part of the fourth side portion SS4. Here, the part of the first side portion SS1 refers to the left edge portion of the first side portion SS1, the part of the second side portion SS2 refers to the lower edge portion of the second side portion SS2, the part of the third side portion SS3 refers to the right edge portion of the third side portion SS3, and the part of the fourth side portion SS4 refers to the upper edge portion of the fourth side portion SS4.

[0086] The second non-display area NDA2 may be disposed outside the third display area DA3. At least a part of the second non-display area NDA2 may be disposed in at least one of the first corner portion CS1, the second corner portion CS2, the third corner portion CS3, and the fourth corner portion CS4. In addition, at least a part of the second non-display area NDA2 may be disposed in at least two of the first side portion SS1, the second side portion SS2, the third side portion SS3, and the fourth side portion SS4.

[0087] For example, at least a part of the second non-display area NDA2 outside the lower left corner of the first display area DA1 may be disposed in the first corner portion CS1, the first side portion SS1, and the second side portion SS2. At least a part of the second non-display area NDA2 outside the lower right corner of the first display area DA1 may be disposed in the second corner portion CS2, the second side portion SS2, and the third side portion SS3. At least a part of the second non-display area NDA2 outside the upper right corner of the first display area DA1 may be disposed in the third corner portion CS3, the third side portion SS3, and the fourth side portion SS4. At least a part of the second non-display area NDA2 outside the upper left corner of the first display area DA1 may be disposed in the fourth corner portion CS4, the first side portion SS1, and the fourth side portion SS4.

[0088] The bending portion BA may extend from the lower side of the second side portion SS2. The bending portion BA may be disposed between the second side portion SS2 and the pad portion PA. The length of the bending portion BA in the first direction (or X-axis direction) may be smaller than the length of the second side portion SS2 in the first direction (or X-axis direction). The bending portion BA may bend along the fifth bending line BL5 below the second side portion SS2.

[0089] The cushion part PA may extend from the lower side of the bending part BA. The length of the cushion part PA in the first direction (or the X-axis direction) may be greater than the length of the bending part BA in the first direction (or the X-axis direction). However, the inventive concept is not limited thereto. For example, according to an exemplary embodiment, the length of the cushion part PA in the first direction (or the X-axis direction) may be substantially the same as the length of the bending part BA in the first direction (or the X-axis direction). The cushion part PA may be bent along the sixth bending line BL6 below the bending part BA. The cushion part PA may be disposed on the bottom surface of the frontward part FS.

[0090] The integrated drive circuit IDC and the pad PAD may be disposed on the cushion part PA. The integrated drive circuit IDC may be formed as an integrated circuit (IC). The integrated drive circuit IDC may be attached to the cushion part PA, for example, in a chip-on-glass (COG) manner, a chip-on-plastic (COP) manner, or an ultrasonic bonding manner. Optionally, the integrated drive circuit IDC may be disposed on a circuit board disposed on the pad PAD.

[0091] The integrated drive circuit IDC may be electrically connected to the pad PAD of the cushion part PA. The integrated drive circuit IDC may receive digital video data and a timing signal via the pad PAD of the cushion part PA. The integrated drive circuit IDC may convert the digital video data into an analog data voltage and may output the analog data voltage to the data lines of the first display area DA1, the second display area DA2, and the third display area DA3.

[0092] The circuit board may be attached to the pad PAD of the cushion part PA via, for example, an anisotropic conductive film. As a result, the pad PAD of the cushion part PA may be electrically connected to the circuit board.

[0093] As Figure 3 shown, the first display area DA1, the second display area DA2, and the third display area DA3 may be disposed in the frontward part FS, the first side part SS1, the second side part SS2, the third side part SS3, the fourth side part SS4, and the first corner part CS1, the second corner part CS2, the third corner part CS3, and the fourth corner part CS4 of the display panel 300. Accordingly, an image may be displayed not only in the frontward part FS and the first side part SS1, the second side part SS2, the third side part SS3, and the fourth side part SS4 of the display panel 300, but also in the first corner part CS1, the second corner part CS2, the third corner part CS3, and the fourth corner part CS4 of the display panel 300.

[0094] Figure 4 is Figure 1 a cross-sectional view of the display device. For example, Figure 4 is a cross-sectional view taken along the Figure 2 line V-V'.

[0095] Referring to Figure 4 , the display panel 300 may include a substrate SUB, a display layer DISL, a sensor electrode layer SENL, a polarizing film PF, and / or a cover window CW.

[0096] The display layer DISL may be disposed on the substrate SUB. The display layer DISL may include a first display area DA1, a second display area DA2, and a third display area DA3, as well as a first non-display area NDA1 and a second non-display area NDA2. In the first display area DA1, the second display area DA2, and the third display area DA3 of the display layer DISL, not only emission areas but also scan lines, data lines, and power lines for driving light-emitting elements may be provided. In the first non-display area NDA1 and the second non-display area NDA2 of the display layer DISL, a scan driving circuit for outputting a scan signal to the scan lines and fan-out lines connecting the data lines and the integrated driving circuit IDC may be provided.

[0097] The display layer DISL may include a TFT layer ( Figure 8 of the TFTL) in which thin-film transistors (TFTs) are formed, a light-emitting element layer ( Figure 8 of the EML) in which light-emitting elements for emitting light are provided, and a packaging layer ( Figure 8 of the TFEL) for packaging the light-emitting element layer.

[0098] The sensor electrode layer SENL may be disposed on the display layer DISL. The sensor electrode layer SENL may include a plurality of sensor electrodes. The sensor electrode layer SENL may use the sensor electrodes to detect a touch input from a person or an object.

[0099] The polarizing film PF may be disposed on the sensor electrode layer SENL. The polarizing film PF may include a first substrate member, a linear polarizer, one or more phase retardation films (such as a quarter-wave (λ / 4) plate and / or a half-wave (λ / 2) plate), and a second substrate member. For example, the first substrate member, the linear polarizer, the λ / 4 plate, the λ / 2 plate, and the second substrate member may be sequentially stacked on the sensor electrode layer SENL.

[0100] The cover window CW may be disposed on the polarizing film PF. The cover window CW may be attached to the polarizing film PF via a transparent bonding member such as an optically clear adhesive (OCA) or an optically clear resin (OCR). The cover window CW may include an inorganic material (such as glass) or an organic material (such as plastic or polymer material).

[0101] The bending part BA can be bent along the fifth bending line BL5 to be disposed on the bottom surface of the second side part SS2. The pad part PA can be bent along the sixth bending line BL6 to be disposed on the bottom surface of the front part FS. The pad part PA can be attached to the bottom surface of the front part FS via an adhesive member ADH. The adhesive member ADH can be, for example, a pressure-sensitive adhesive (PSA).

[0102] Figure 5 is a layout diagram showing Figure 4 an exemplary sensor electrode layer of a display panel.

[0103] According to an exemplary embodiment, the sensor electrodes SE of the sensor electrode layer SENL can include two types of electrodes (e.g., driving electrodes TE and sensing electrodes RE), and can be driven in a mutual capacitance manner by applying a driving signal to the driving electrodes TE and detecting the voltage charged in the mutual capacitance of the sensing electrodes RE. However, the inventive concept is not limited thereto.

[0104] For ease of explanation, Figure 5 only the sensor electrodes (TE and RE), dummy patterns DE, sensor lines SL (TL1, TL2, and RL), and sensor pads (TP1 and TP2) are shown.

[0105] Referring to Figure 5 , the sensor electrode layer SENL includes a touch sensor area TSA in which a touch input from a user is detected and a touch peripheral area TPA disposed on the periphery of the touch sensor area TSA. The touch sensor area TSA can overlap with Figure 3 the first display area DA1, the second display area DA2, and the third display area DA3 of Figure 3 , and the touch peripheral area TPA can overlap with

[0106] the first non-display area NDA1 and the second non-display area NDA2 of

[0107] The touch sensor area TSA can include sensor electrodes SE and dummy patterns DE. The sensor electrodes SE can be electrodes for forming a mutual capacitance to detect a touch input from a user or an object.

[0108] The driving electrodes TE can be arranged substantially parallel to each other in a first direction (or the X-axis direction) and in a second direction (or the Y-axis direction). Each pair of adjacent driving electrodes TE in the first direction (or the X-axis direction) can be electrically isolated. Each pair of adjacent driving electrodes TE in the second direction (or the Y-axis direction) can be electrically connected. For example, as Figure 7 shown, the paired adjacent driving electrodes TE in the second direction (or the Y-axis direction) can be connected via a first connection portion BE1.

[0109] The dummy pattern DE can be surrounded by the driving electrodes TE or the sensing electrodes RE. The dummy pattern DE can be electrically isolated from the driving electrodes TE or the sensing electrodes RE. The dummy pattern DE can be spaced apart from the driving electrodes TE or the sensing electrodes RE. The dummy pattern DE can be electrically floating.

[0110] Figure 5 It is shown that the driving electrodes TE, the sensing electrodes RE, and the dummy pattern DE have a rhombus shape in a plan view. However, the inventive concept is not limited thereto. For example, according to an exemplary embodiment, the driving electrodes TE, the sensing electrodes RE, and the dummy pattern DE can have various other shapes such as a rectangular shape, a non-quadrilateral polygon shape, a circular shape, or an elliptical shape in a plan view other than the rhombus shape.

[0111] The sensor lines SL (TL1, TL2, and RL) can be provided in the touch peripheral area TPA. The sensor lines SL (TL1, TL2, and RL) can include a sensing line RL connected to the sensing electrode RE and a first driving line TL1 and a second driving line TL2 connected to the driving electrode TE.

[0112] The sensing electrodes RE provided on one side of the touch sensor area TSA can be connected to the sensing lines RL in a one-to-one correspondence. For example, referring to Figure 5 , the sensing electrodes RE electrically connected in the first direction (or the X-axis direction) at the right end of the touch sensor area TSA can be connected to the sensing line RL. The sensing lines RL can be connected to the second sensor pads TP2 in a one-to-one correspondence. Thus, the touch driving circuit can electrically connect the sensing electrodes RE.

[0113] The driving electrodes TE provided on one side of the touch sensor area TSA can be connected to the first driving line TL1 in a one-to-one correspondence, and the driving electrodes TE provided on the other side of the touch sensor area TSA can be connected to the second driving line TL2 in a one-to-one correspondence. For example, referring to Figure 5, a driving electrode TE provided at a lower end of the touch sensor area TSA may be connected to a first driving line TL1, and a driving electrode TE provided at an upper end of the touch sensor area TSA may be connected to a second driving line TL2. The second driving line TL2 may be connected to the driving electrode TE on the upper side of the touch sensor area TSA via the left outer side of the touch sensor area TSA.

[0114] The first driving line TL1 and the second driving line TL2 may be connected to the first sensor pad TP1 in a one-to-one correspondence. Accordingly, the touch driving circuit may be electrically connected to the driving electrode TE. Since the driving electrode TE is connected to the driving lines (TL1 and TL2) on either side of the touch sensor area TSA and thus receives a touch driving signal, it is possible to prevent a difference that may occur due to an RC delay in the touch driving signal between the touch driving signal applied to the driving electrode TE provided in the lower part of the touch sensor area TSA and the touch driving signal applied to the driving electrode TE provided in the upper part of the touch sensor area TSA.

[0115] A first sensor pad area TPA1 in which the first sensor pad TP1 is provided may be provided on one side of a display pad area DPA in which a display pad DP is provided. A second sensor pad area TPA2 in which the second sensor pad TP2 is provided may be provided on the other side of the display pad area DPA. The display pad DP may be connected to a data line of the display panel 300.

[0116] The display pad area DPA, the first sensor pad area TPA1, and the second sensor pad area TPA2 may correspond to Figure 3 the pads PAD of the display panel 300. A circuit board may be provided on the display pad DP, the first sensor pad TP1, and the second sensor pad TP2. The display pad DP, the first sensor pad TP1, and the second sensor pad DP2 may be electrically connected to the circuit board via a low-resistance, high-reliability material (such as ACF or SAP for example). Accordingly, the display pad area DPA, the first sensor pad area TPA1, and the second sensor pad area TPA2 may be electrically connected to the touch driving circuit provided on the circuit board.

[0117] Figure 6A is a layout diagram showing a first display area, a second display area, a third display area, and a second non-display area of a display panel according to an exemplary embodiment of the inventive concept. For example, Figure 6A is a diagram showing Figure 3 an enlarged layout example of area A, and shows Figure 3 a part of the first display area DA1, a part of the second display area DA2, a part of the third display area DA3, and a part of the second non-display area NDA2 near a first corner part CS1.

[0118] Referring to Figure 6A , the intersection point CRP between the first curved line BL1 and the second curved line BL2 can be set in the first display area DA1. In this case, the first display area DA1 can be set in the front portion FS, the first side portion SS1, the second side portion SS2, and the first corner portion CS1, the second display area DA2 can be set in the first side portion SS1, the second side portion SS2, and the first corner portion CS1, the third display area DA3 can be set in the first side portion SS1, the second side portion SS2, and the first corner portion CS1, and the second non-display area NDA2 can be set in the first side portion SS1, the second side portion SS2, and the first corner portion CS1. The first corner portion CS1 can correspond to the lower left quadrant defined by the intersection of the first curved line BL1 and the second curved line BL2. For example, in an exemplary embodiment, the first corner portion CS1 can refer to the portion of the display panel 300 that is set in the lower left quadrant defined by the intersection of the first curved line BL1 and the second curved line BL2.

[0119] The first display area DA1 can include a first emission area. In addition, since the first display area DA1 is superimposed on the touch sensor area TSA, the first display area DA1 can include sensor electrodes SE. As Figure 5 shown, the sensor electrodes SE can include driving electrodes TE and sensing electrodes RE. The first emission area, the driving electrodes TE, and the sensing electrodes RE of the first display area DA1 will be described in further detail below with reference to Figure 7 and Figure 8 .

[0120] The second display area DA2 can be set on the outside of the first display area DA1. The second display area DA2 can include a second emission area and a first sensor line SL1. The first sensor line SL1 can be defined as a sensor line that is set in the second display area DA2 and connected to at least some of the sensor electrodes SE of the first display area DA1. For example, the first sensor line SL1 can include a first driving line TL1 and a second driving line TL2. The first driving line TL1 is connected to the driving electrode TE in the portion of the first display area DA1 adjacent to the second display area DA2, and the second driving line TL2 is connected to the driving electrode TE in the upper portion of the first display area DA1. The first sensor line SL1 can be set not only in the second display area DA2 but also in the first non-display area NDA1 and / or the second non-display area NDA2 that are set adjacent to the first display area DA1 and the second display area DA2.

[0121] The third display area DA3 may be disposed outside the second display area DA2. The third display area DA3 may include a cutout portion CP isolated from each other and a third emission area disposed in the cutout portion CP.

[0122] A first end of the cutout portion CP may be connected to the second display area DA2, and a second end of the cutout portion CP may be connected to the second non-display area NDA2. In an exemplary embodiment, the cutout portion CP may have a substantially trapezoidal shape in a plan view. The width of the cutout portion CP may gradually increase or decrease from the second display area DA2 to the second non-display area NDA2. Alternatively, in an exemplary embodiment, the cutout portion CP may have a rectangular shape in a plan view.

[0123] The width of the middle portion of the third display area DA3 may be larger than the widths of both ends of the third display area DA3. For example, the third display area DA3 may be formed in a crescent shape in a plan view. Accordingly, each pair of adjacent cutout portions CP in the third display area DA3 may have different sizes. For example, the size of the cutout portion CP may gradually decrease from the center of the third display area DA3 to either end of the third display area DA3.

[0124] The cutout portion CP may be formed by cutting the display panel 300 with light emitted by a laser. Accordingly, a first cut gap CG1 may be formed between the cutout portions CP. Since the third emission area is disposed in the cutout portion CP, the maximum width of the cutout portion CP may be larger than the maximum width of the first cut gap CG1.

[0125] The following will refer to Figure 15 and Figure 16 to describe the cutout portion CP and the third emission area of the third display area DA3 in further detail.

[0126] In a case where a non-display area in which an image is not displayed is disposed between the first display area DA1 and the third display area DA3, when images are displayed in the first display area DA1 and the third display area DA3, a user may recognize the existence of the non-display area between the first display area DA1 and the third display area DA3. That is, the user may recognize parts of the images displayed in the first display area DA1 and the third display area DA3 as being separated from each other. However, according to an exemplary embodiment, since the second display area DA2 including the second emission area as shown in Figure 6A is disposed between the first display area DA1 and the third display area DA3, it is possible to prevent the non-display area between the first display area DA1 and the third display area DA3 from being visible to the user. The following will refer to Figures 9 to 14 to describe the second emission area of the second display area DA2 in further detail.

[0127] The second non-display area NDA2 may be disposed outside the third display area DA3. The second non-display area NDA2 may include an incision connection part CBP connected to the incision part CP and an incision common pattern CCP commonly connected to the incision connection part CBP. A first end of the incision connection part CBP may be connected to the incision part CP, and a second end of the incision connection part CBP may be connected to the incision common pattern CCP. The incision common pattern CCP may be disposed on the outermost side of the second non-display area NDA2.

[0128] The incision connection part CBP may be formed by cutting the display panel 300 through light emitted by a laser. A second incision gap CG2 may be formed between the incision connection parts CBP.

[0129] The maximum width of the incision connection part CBP may be greater than or less than the maximum width of the second incision gap CG2. The incision connection part CBP may be formed in a zigzag shape including a plurality of bending parts. Accordingly, the incision connection part CBP may be designed to be suitable for stretching or contracting.

[0130] Since the incision part CP disposed in the third display area DA3 and the incision connection part CBP disposed in the second non-display area NDA2 as shown in Figure 6A are designed to be suitable for stretching or contracting, strain and stress applied to the emission area of the third display area DA3 due to the double curvature can be reduced.

[0131] The portions of the first display area DA1, the second display area DA2, and the third display area DA3 each disposed in Figure 3 the second corner part CS2 to the fourth corner part CS4 and the portions of the second non-display area NDA2 each disposed in Figure 3 the second corner part CS2 to the fourth corner part CS4 may be similar to Figure 6AThose shown in [reference]. However, the portion of the second display area DA2 disposed in the second corner portion CS2 may be different from the portion of the second display area DA2 disposed in the first corner portion CS1 in that: the first sensor line SL1 includes a sensing line RL connected to a sensing electrode RE in the first display area DA1 instead of the second driving line TL2. In addition, the portion of the second display area DA2 disposed in the third corner portion CS3 may be different from the portion of the second display area DA2 disposed in the first corner portion CS1 in that: the first sensor line SL1 includes the sensing line RL, and the first sensor line SL1 does not include the first driving line TL1. In addition, the portion of the second display area DA2 disposed in the fourth corner portion CS4 may be different from the portion of the second display area DA2 disposed in the first corner portion CS1 in that: the first sensor line SL1 includes the second driving line TL2 and does not include the first driving line TL1.

[0132] In an exemplary embodiment, the display device 10 may include a display panel 300, and the display panel 300 may include a first display area DA1, a second display area DA2, and a third display area DA3. The first display area DA1 may include a plurality of first emission areas (see, for example, Figure 7 EA1 in [reference]) and a plurality of sensor electrodes SE, the second display area DA2 may include a plurality of second emission areas (see, for example, Figures 9 to 14 EA2 in [reference]) and a plurality of first sensor lines SL1 electrically connected to at least some of the sensor electrodes SE, and the third display area DA3 may include a plurality of third emission areas (see, for example, Figure 15 EA3 in [reference]) and a plurality of third sensor lines (see, for example, Figure 22 SL3 in [reference]) connected to at least some of the sensor electrodes SE. The second display area DA2 may be disposed in a corner portion (e.g., CS1) of the display device 10 between the first display area DA1 and the third display area DA3.

[0133] Figure 6B is a layout diagram showing the first display area, the second display area, the third display area, and the second non-display area of a display panel according to an exemplary embodiment of the inventive concept. Figure 6C is a layout diagram showing the first display area, the second display area, the third display area, and the second non-display area of a display panel according to an exemplary embodiment of the inventive concept. Figure 6B and Figure 6C are enlarged layout diagrams showing other examples of region A of Figure 3 . For ease of explanation, the differences compared to Figure 6A will be mainly described hereinafter Figure 6B and Figure 6C, and further descriptions of the previously described elements and technical aspects can be omitted.

[0134] Referring to Figure 6B , the intersection point CRP between the first bending curve BL1 and the second bending curve BL2 can be set at the boundary between the first display area DA1 and the second display area DA2. Optionally, referring to Figure 6C , the intersection point CRP between the first bending curve BL1 and the second bending curve BL2 can be set at the boundary between the second display area DA2 and the third display area DA3. Optionally, in an exemplary embodiment, the intersection point CRP between the first bending curve BL1 and the second bending curve BL2 can be set in the second display area DA2 or the third display area DA3.

[0135] Figure 7 is a layout diagram showing Figure 6A the sensor electrodes and the first emission area in the first display area.

[0136] Referring to Figure 7 , the driving electrode TE, the sensing electrode RE, and the dummy pattern DE can be disposed in the same layer and spaced apart from each other. That is, a gap can be formed between the driving electrode TE and the sensing electrode RE.

[0137] The dummy pattern DE can also be disposed in the same layer as the driving electrode TE and the sensing electrode RE. That is, gaps can be formed between the driving electrode TE and the dummy pattern DE and between the sensing electrode RE and the dummy pattern DE.

[0138] The first connection portion BE1 can be disposed in a different layer from the driving electrode TE and the sensing electrode RE. The first connection portion BE1 can be bent at least once. Figure 7 Shows that each of the first connection portions BE1 is formed in the shape of an angle bracket (e.g., "<" or ">"), but the planar shape of the first connection portion BE1 is not particularly limited. Since the paired adjacent driving electrodes TE in the second direction (or Y-axis direction) are connected by a plurality of first connection portions BE1, even if one of the first connection portions BE1 is disconnected, the driving electrodes TE can be stably connected in the second direction (or Y-axis direction). Figure 7 Shows that two adjacent driving electrodes TE are connected by one first connection portion BE1, but the number of the first connection portions BE1 is not particularly limited.

[0139] The first connection part BE1 can be disposed in a different layer from the driving electrode TE and the sensing electrode RE. The first connection part BE1 can be stacked with their respective driving electrodes TE that are adjacent in pairs in the second direction (or Y-axis direction) in the third direction (or Z-axis direction). The first connection part BE1 can be stacked with the sensing electrode RE in the third direction (or Z-axis direction). One side of each of the first connection parts BE1 can be connected to one of a pair of adjacent driving electrodes TE in the second direction (or Y-axis direction) via a first touch contact hole TCNT1, and the other side of each of the first connection parts BE1 can be connected to the other driving electrode TE via another first touch contact hole TCNT1.

[0140] Due to the presence of the first connection part BE1, the driving electrode TE and the sensing electrode RE can be electrically isolated at their intersection points. As a result, a mutual capacitance can be formed between the driving electrode TE and the sensing electrode RE.

[0141] The driving electrode TE, the sensing electrode RE, and the first connection part BE1 can be formed in a grid structure or a fishnet structure in a plan view. In addition, the dummy pattern DE can be formed in a grid structure or a fishnet structure in a plan view. Therefore, in an exemplary embodiment, the driving electrode TE, the sensing electrode RE, the first connection part BE1, and the dummy pattern DE do not overlap with the first emission region EA1. Therefore, it is possible to prevent the brightness of the light emitted from the first emission region EA1 from being reduced due to being blocked by the driving electrode TE, the sensing electrode RE, the first connection part BE1, and the dummy pattern DE.

[0142] Each of the first emission regions EA1 can include a first sub-emission region SEA1, a second sub-emission region SEA2, a third sub-emission region SEA3, and a fourth sub-emission region SEA4 that respectively emit light of a first color, a second color, a third color, and a fourth color. For example, the first color can be red, the second color and the fourth color can be green, and the third color can be blue.

[0143] The first sub-emission region SEA1, the second sub-emission region SEA2, the third sub-emission region SEA3, and the fourth sub-emission region SEA4 can have a rhombus shape or a rectangular shape in a plan view. However, the inventive concept is not limited thereto. For example, according to an exemplary embodiment, the first sub-emission region SEA1, the second sub-emission region SEA2, the third sub-emission region SEA3, and the fourth sub-emission region SEA4 can have various other shapes such as a non-quadrilateral polygon shape, a circular shape, or an elliptical shape in a plan view. Figure 7It is shown that among the first sub-emission area SEA1, the second sub-emission area SEA2, the third sub-emission area SEA3, and the fourth sub-emission area SEA4, the size of the third sub-emission area SEA3 is the largest, and the sizes of the second sub-emission area SEA2 and the fourth sub-emission area SEA4 are the smallest. However, the inventive concept is not limited thereto.

[0144] The second sub-emission area SEA2 and the fourth sub-emission area SEA4 may be arranged in odd rows. The second sub-emission area SEA2 and the fourth sub-emission area SEA4 may be arranged to be adjacent to each other in the first direction (or X-axis direction) in each odd row. The second sub-emission area SEA2 and the fourth sub-emission area SEA4 may be alternately arranged in each odd row. Each of the second sub-emission areas SEA2 may have a short side extending in the fifth direction DR5 and a long side in the fourth direction DR4 (e.g., a long side relatively longer than the short side). Each of the fourth sub-emission areas SEA4 may have a long side extending in the fifth direction DR5 and a short side extending in the fourth direction DR4 (e.g., a short side relatively shorter than the long side). The fifth direction DR5 may be a direction inclined at an angle of approximately 45° between the first direction (or X-axis direction) and the second direction (or Y-axis direction). The fourth direction DR4 may be a direction orthogonal to the fifth direction DR5.

[0145] The first sub-emission area SEA1 and the third sub-emission area SEA3 may be arranged in even rows. The first sub-emission area SEA1 and the third sub-emission area SEA3 may be arranged to be adjacent to each other in the first direction (or X-axis direction) in each even row. The first sub-emission area SEA1 and the third sub-emission area SEA3 may be alternately arranged in each even row.

[0146] The second sub-emission area SEA2 and the fourth sub-emission area SEA4 may be arranged in odd columns. The second sub-emission area SEA2 and the fourth sub-emission area SEA4 may be arranged to be adjacent to each other in the second direction (or Y-axis direction) in each odd column.

[0147] The first sub-emission area SEA1 and the third sub-emission area SEA3 may be arranged in even columns. The first sub-emission area SEA1 and the third sub-emission area SEA3 may be arranged to be adjacent to each other in each even column. The first sub-emission area SEA1 and the third sub-emission area SEA3 may be alternately arranged in each even column.

[0148] Figure 8 is a cross-sectional view taken along Figure 7 the line I-I'.

[0149] Referring to Figure 8, a display layer DISL including a TFT layer TFTL, a light-emitting element layer EML, and a thin film encapsulation layer TFEL may be disposed on a substrate SUB, and a sensor electrode layer SENL including a sensor electrode SE may be disposed on the display layer DISL.

[0150] A first buffer film BF1 may be disposed on a first surface of the substrate SUB, and a second buffer film BF2 may be disposed on the first buffer film BF1. The first buffer film BF1 and the second buffer film BF2 may protect a TFT ST of the TFT layer TFTL and a light-emitting layer 172 of the light-emitting element layer EML from moisture that may penetrate the substrate SUB, which may be vulnerable to moisture. For example, each of the first buffer film BF1 and the second buffer film BF2 may be formed as a multilayer film in which one or more inorganic films selected from, for example, a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, and an aluminum oxide layer are alternately stacked. In an exemplary embodiment, one of the first buffer film BF1 and the second buffer film BF2 may be omitted.

[0151] A first light-blocking layer BML may be disposed on the first buffer film BF1. The first light-blocking layer BML may be formed as a single film or a multilayer film including, for example, molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), copper (Cu), or an alloy thereof. Alternatively, the first light-blocking layer BML may be an organic film containing a black pigment.

[0152] An active layer ACT of the TFT ST may be disposed on the second buffer film BF2. The active layer ACT may include, for example, polysilicon, single-crystalline silicon, low-temperature polysilicon (LTPS), amorphous silicon, or an oxide semiconductor material. In a case where the active layer ACT includes polysilicon or an oxide semiconductor material, an ion-doped region of the active layer ACT may be a conductive region having conductivity.

[0153] The active layer ACT may be stacked with the first light-blocking layer BML in a third direction (or Z-axis direction). Since light incident through the substrate SUB may be blocked by the first light-blocking layer BML, leakage current flowing into the active layer ACT due to the incident light may be prevented.

[0154] A gate insulating film 130 may be formed on the active layer ACT. The gate insulating film 130 may be formed as an inorganic film, such as, for example, a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, or an aluminum oxide layer.

[0155] The gate electrode G of the TFT ST can be disposed on the gate insulating film 130. The gate electrode G of the TFT ST can be stacked with the active layer ACT in the third direction (or Z-axis direction). The portion of the active layer ACT stacked with the gate electrode G in the third direction (or Z-axis direction) can be the channel region CHA. The gate electrode G can be formed as a single film or a multi-layer film including, for example, Mo, Al, Cr, Au, Ti, Ni, Nd, Cu, or an alloy thereof.

[0156] The first interlayer insulating film 141 can be disposed on the gate electrode G. The first interlayer insulating film 141 can be formed as an inorganic film, such as a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, or an aluminum oxide layer as an example. The first interlayer insulating film 141 can include a plurality of inorganic films.

[0157] The capacitor electrode CAE can be disposed on the first interlayer insulating film 141. The capacitor electrode CAE can be stacked with the gate electrode G in the third direction (or Z-axis direction). The capacitor electrode CAE can be formed as a single film or a multi-layer film including, for example, Mo, Al, Cr, Au, Ti, Ni, Nd, Cu, or an alloy thereof.

[0158] The second interlayer insulating film 142 can be disposed on the capacitor electrode CAE. The second interlayer insulating film 142 can be formed as an inorganic film, such as a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, or an aluminum oxide layer as an example. The second interlayer insulating film 142 can include a plurality of inorganic films.

[0159] The first electrode S and the second electrode D of the TFT ST can be disposed on the second interlayer insulating film 142. The first electrode S and the second electrode D can be formed as a single film or a multi-layer film including, for example, Mo, Al, Cr, Au, Ti, Ni, Nd, Cu, or an alloy thereof. The first electrode S and the second electrode D of the TFT ST can correspond to the source electrode and the drain electrode of the TFT ST.

[0160] The first electrode S of the TFT ST can be connected to the first conductive region COA1 through a contact hole penetrating the gate insulating film 130, the first interlayer insulating film 141, and the second interlayer insulating film 142. The first conductive region COA1 is disposed on the first side of the channel region CHA of the active layer ACT. The second electrode D of the TFT ST can be connected to the second conductive region COA2 through a contact hole penetrating the gate insulating film 130, the first interlayer insulating film 141, and the second interlayer insulating film 142. The second conductive region COA2 is disposed on the second side of the channel region CHA of the active layer ACT.

[0161] The first organic film 150 for flattening the height difference formed by the TFT ST may be disposed on the first electrode S and the second electrode D. The first organic film 150 may be formed as an organic film including, for example, an acrylic resin, an epoxy resin, a phenolic resin, a polyamide resin, or a polyimide resin.

[0162] The first connection electrode ANDE1 may be disposed on the first organic film 150. The first connection electrode ANDE1 may be connected to the second electrode D of the TFT ST through a contact hole penetrating the first organic film 150. The first connection electrode ANDE1 may be formed as a single-layer film or a multi-layer film including, for example, Mo, Al, Cr, Au, Ti, Ni, Nd, Cu, or an alloy thereof.

[0163] The second organic film 160 may be disposed on the first connection electrode ANDE1. The second organic film 160 may be formed as an organic film including, for example, an acrylic resin, an epoxy resin, a phenolic resin, a polyamide resin, or a polyimide resin.

[0164] Figure 8 It is shown that the TFT ST is formed as a top-gate TFT in which the gate electrode G is disposed above the active layer ACT. However, the inventive concept is not limited thereto. For example, according to an exemplary embodiment, the TFT ST may be formed as a bottom-gate TFT in which the gate electrode G is disposed below the active layer ACT, or as a double-gate TFT in which the gate electrode G is disposed above and below the active layer ACT.

[0165] The light-emitting element layer EML is disposed on the TFT layer TFTL. The light-emitting element layer EML may include a light-emitting element 170 and a bank 180.

[0166] Each of the light-emitting elements 170 may include a first light-emitting electrode 171, a light-emitting layer 172, and a second light-emitting electrode 173. Each of the first emission regions EA1 may be a region in which the first light-emitting electrode 171, the light-emitting layer 172, and the second light-emitting electrode 173 are sequentially stacked such that holes from the first light-emitting electrode 171 and electrons from the second light-emitting electrode 173 may be combined in the light-emitting layer 172 to emit light. In this case, the first light-emitting electrode 171 may be an anode electrode, and the second light-emitting electrode 173 may be a cathode electrode.

[0167] The first light-emitting electrode 171 may be formed on the second organic film 160. The first light-emitting electrode 171 may be connected to the first connection electrode ANDE1 through a contact hole penetrating the second organic film 160.

[0168] In a top emission structure in which the light emitting element 170 emits light in a direction from the light emitting layer 172 of the light emitting element 170 to the second light emitting electrode 173 of the light emitting element 170, the first light emitting electrode 171 may be formed as a single layer of, for example, Mo, Ti, Cu, or Al, or may be formed as a stack of, for example, Al and Ti (e.g., Ti / Al / Ti), a stack of Al and ITO (e.g., ITO / Al / ITO), a layer of a silver (Ag)-palladium (Pd)-copper (Cu) (APC) alloy, or a stack of the APC alloy and ITO (e.g., ITO / APC / ITO).

[0169] The bank 180 defines a first emission region EA1. To this end, the bank 180 may be formed on the second organic film 160 to expose a part of the first light emitting electrode 171 of the light emitting element 170. The bank 180 may cover the edges of each of the first light emitting electrodes 171. The bank 180 may be disposed in a contact hole penetrating the second organic film 160. As a result, the contact hole of the second organic film 160 may be filled with the bank 180. The bank 180 may be formed as an organic film including, for example, an acrylic resin, an epoxy resin, a phenolic resin, a polyamide resin, or a polyimide resin.

[0170] The light emitting layer 172 is formed on the first light emitting electrode 171. The light emitting layer 172 may include an organic material that emits light of a predetermined color. For example, the light emitting layer 172 may include a hole transport layer, an organic material layer, and an electron transport layer. In this example, the organic material layer may include a host and a dopant. The organic material layer may include a material capable of emitting light of a predetermined color and may be formed of a phosphorescent material or a fluorescent material.

[0171] For example, the organic material layer of the light emitting layer 172 that emits light of a first color formed in the first sub-emission region SEA1 may be formed of a phosphorescent material including a host material including, for example, 4,4'-bis(N-carbazolyl)-1,1'-biphenyl (CBP) or 1,3-bis(carbazol-9-yl)benzene (mCP) and at least one dopant material selected from, for example, bis(1-phenylisoquinoline)iridium(III) acetylacetonate (PIQIr(acac)), bis(1-phenylquinoline)iridium(III) acetylacetonate (PQIr(acac)), tris(1-phenylquinoline)iridium(III) (PQIr), and platinum octaethylporphyrin (PtOEP). In an exemplary embodiment, the organic material layer of the light emitting layer 172 formed in the first sub-emission region SEA1 may be formed of a fluorescent material including, for example, PBD:Eu(DBM)3(Phen) or perylene. However, the inventive concept is not limited to these examples.

[0172] The organic material layer that emits light of a second color in the second sub-emission region SEA2 may be formed of, for example, a phosphorescent material, which includes a host material and a dopant material. The host material includes, for example, CBP or mCP, and the dopant material includes, for example, fac-tris(2-phenylpyridine) iridium (Ir(ppy)3). In an exemplary embodiment, the organic material layer of the light-emitting layer 172 formed in the second sub-emission region SEA2 may be formed of a fluorescent material including, for example, tris(8-hydroxyquinoline) aluminum (Alq3). However, the inventive concept is not limited to these examples.

[0173] The organic material layer that emits light of a third color in the third sub-emission region SEA3 may be formed of a phosphorescent material, which includes a host material and a dopant material. The host material includes, for example, CBP or mCP, and the dopant material includes, for example, (4,6-F2ppy)2Irpic or L2BD111. However, the inventive concept is not limited to this example.

[0174] The second light-emitting electrode 173 may be formed on the light-emitting layer 172. The second light-emitting electrode 173 may cover the light-emitting layer 172. The second light-emitting electrode 173 may be a common layer formed for all display pixels. A cover layer may be formed on the second light-emitting electrode 173.

[0175] In a top-emission structure, the second light-emitting electrode 173 may be formed of a transparent conductive oxide (TCO) material (such as ITO or IZO as an example) or a semi-transparent metal material (such as magnesium (Mg), Ag, or an alloy thereof as an example). In the case where the second light-emitting electrode 173 is formed of a semi-transparent metal material, the light-emitting efficiency of the light-emitting element 170 may be improved due to a microcavity.

[0176] The light-emitting layer 172 may be disposed on the top surface of the first light-emitting electrode 171 and the inclined surface of the bank 180. The second light-emitting electrode 173 may be disposed on the top surface of the light-emitting layer 172 and the inclined surface of the bank 180.

[0177] The encapsulation layer TFEL may be formed on the light-emitting element layer EML. The encapsulation layer TFEL may include at least one inorganic film, and the at least one inorganic film may prevent oxygen or moisture from penetrating into the light-emitting element layer EML. The encapsulation layer TFEL may further include at least one organic film, and the at least one organic film may protect the light-emitting element layer EML from foreign substances such as dust. The inorganic film may be formed as a multilayer film in which one or more inorganic films selected from, for example, a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, and an aluminum oxide layer are alternately stacked. The organic film may be formed of, for example, an acrylic resin, an epoxy resin, a phenolic resin, a polyamide resin, or a polyimide resin.

[0178] In a case where a second substrate is disposed on the light-emitting element layer EML instead of the encapsulation layer TFEL, the space between the light-emitting element layer EML and the second substrate may be empty under vacuum or may have a filling film disposed therein. The filling film may be, for example, an epoxy resin filling film or a silicone resin filling film.

[0179] The sensor electrode layer SENL is disposed on the encapsulation layer TFEL. The sensor electrode layer SENL may include a light-blocking film and a sensor electrode SE. As described above, the sensor electrode SE may include a driving electrode TE and a sensing electrode RE.

[0180] A third buffer film BF3 may be disposed on the encapsulation layer TFEL. The third buffer film BF3 may be a layer having an insulating function and an optical function. The third buffer film BF3 may include at least one inorganic film. For example, the third buffer film BF3 may be formed as a multilayer film in which one or more inorganic films selected from, for example, a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, and an aluminum oxide layer are alternately stacked.

[0181] A first connection portion BE1 may be disposed on the third buffer film BF3. The first connection portion BE1 may be formed as a single layer of, for example, Mo, Ti, Cu, or Al, or may be formed as a stack of, for example, Al and Ti (e.g., Ti / Al / Ti), a stack of Al and ITO (e.g., ITO / Al / ITO), a layer of an APC alloy, or a stack of an APC alloy and ITO (e.g., ITO / APC / ITO).

[0182] A first sensor insulating film TINS1 may be disposed on the first connection portion BE1. The first sensor insulating film TINS1 may be a layer having an insulating function and an optical function. The first sensor insulating film TINS1 may be formed as an inorganic film, such as, for example, a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, or an aluminum oxide layer.

[0183] The driving electrode TE and the sensing electrode RE may be disposed on the first sensor insulating film TINS1. In an exemplary embodiment, the driving electrode TE and the sensing electrode RE do not overlap with the first emission region EA1. The driving electrode TE and the sensing electrode RE may be formed as a single layer of, for example, Mo, Ti, Cu, or Al, or may be formed as a stack of, for example, Al and Ti (e.g., Ti / Al / Ti), a stack of Al and ITO (e.g., ITO / Al / ITO), a layer of an APC alloy, or a stack of an APC alloy and ITO (e.g., ITO / APC / ITO).

[0184] The second sensor insulating film TINS2 may be disposed on the driving electrode TE and the sensing electrode RE. The second sensor insulating film TINS2 may be a layer having an insulating function and an optical function. The second sensor insulating film TINS2 may include at least one of an inorganic film and an organic film. The inorganic film may be, for example, a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, or an aluminum oxide layer. The organic film may be formed of, for example, an acrylic resin, an epoxy resin, a phenolic resin, a polyamide resin, or a polyimide resin.

[0185] Figure 9 is a layout diagram showing Figure 6A the exemplary first sensor lines and the exemplary second emission regions of the second display region. Figure 9 is a layout diagram showing Figure 6A the enlarged layout of region B.

[0186] Referring to Figure 9 , the first sensor line SL1 may extend in the sixth direction DR6. The sixth direction DR6 may be a direction inclined at an angle of about 135° with respect to the first direction (or the X-axis direction), but the inventive concept is not limited thereto. The first sensor line SL1 may be arranged in the first direction (or the X-axis direction). The distance in the first direction (or the X-axis direction) between the first sensor lines SL1 or the distance in the first direction (or the X-axis direction) between the second emission regions EA2 may be about several micrometers (μm).

[0187] The second emission region EA2 may be disposed between the first sensor lines SL1. The second emission region EA2 may be arranged in the sixth direction DR6 between the first sensor lines SL1. One sensor line SL1 may be disposed between each pair of adjacent second emission regions EA2 in the first direction (or the X-axis direction). In an exemplary embodiment, as shown in Figure 9 , the first sensor line SL1 does not overlap with the second emission region EA2. In an exemplary embodiment, the second emission region EA2 may be disposed between at least one of the first sensor lines SL1 and the third emission region provided in the third display region DA3 (see, for example, Figure 9 and Figure 6A ).

[0188] Each of the second emission regions EA2 may include a first sub-emission region SEA1', a second sub-emission region SEA2', and a third sub-emission region SEA3' that respectively emit light of a first color, a second color, and a third color. For example, the first color may be red, the second color may be green, and the third color may be blue.

[0189] The first sub-emission area SEA1', the second sub-emission area SEA2', and the third sub-emission area SEA3' may be arranged in a first direction (or X-axis direction). The first sub-emission area SEA1', the second sub-emission area SEA2', and the third sub-emission area SEA3' may have a rectangular shape in a plan view, but the inventive concept is not limited thereto. For example, the first sub-emission area SEA1', the second sub-emission area SEA2', and the third sub-emission area SEA3' may have a rectangular shape in a plan view, the rectangular shape having a short side extending in the first direction (or X-axis direction) and a long side extending in a second direction (or Y-axis direction) (e.g., a long side relatively longer than the short side), but the inventive concept is not limited thereto. Optionally, the first sub-emission area SEA1', the second sub-emission area SEA2', and the third sub-emission area SEA3' may have various other shapes in a plan view (such as, for example, a non-quadrilateral polygon shape, a circular shape, or an elliptical shape). Figure 9 It is shown that the first sub-emission area SEA1', the second sub-emission area SEA2', and the third sub-emission area SEA3' have substantially the same size, but the inventive concept is not limited thereto. For example, according to an exemplary embodiment, the first sub-emission area SEA1', the second sub-emission area SEA2', and the third sub-emission area SEA3' may have different sizes.

[0190] The first dam DAM1 may be provided on the left edge of the second display area DA2. The first dam DAM1 may be provided between at least one of the first sensor lines SL1 and a cutout portion CP in which the third emission area is provided. As Figure 17 shown, the first dam DAM1 may be a structure for preventing an organic film from overflowing from the encapsulation layer TFEL. The first dam DAM1 may extend in a sixth direction DR6.

[0191] The cutout portion CP of the third display area DA3 may be provided outside the second display area DA2.

[0192] Among the first sensor line SL1 and the second emission area EA2, if only the first sensor line SL1 is provided in the second display area DA2 and the second emission area EA2 is not provided in the second display area DA2, then the second display area DA2 may be a non-display area that does not display an image.

[0193] As Figure 9As shown, a second display area DA2 including a second emission area EA2 is disposed between a part of a first display area DA1 in a forward part FS and a part of a third display area DA3 in a first corner part CS1. Accordingly, a non-display area between a part of the first display area DA1 in the forward part FS and a part of the third display area DA3 in the first corner part CS1 can be prevented from being visible to a user.

[0194] Figure 10 is a layout diagram showing Figure 6A an exemplary first sensor line and an exemplary second emission area of a second display area.

[0195] Figure 10 An exemplary embodiment of Figure 9 differs from an exemplary embodiment of Figure 7 in that each of the second emission areas EA2 includes a first sub-emission area SEA1', a second sub-emission area SEA2', a third sub-emission area SEA3', and a fourth sub-emission area SEA4' as shown in

[0196] instead of a first sub-emission area SEA1', a second sub-emission area SEA2', and a third sub-emission area SEA3'. For ease of explanation, further description of previously described elements and technical aspects may be omitted.

[0196] Referring to Figure 10 , each of the second emission areas EA2 may include a first sub-emission area SEA1', a second sub-emission area SEA2', a third sub-emission area SEA3', and a fourth sub-emission area SEA4' that respectively emit light of a first color, a second color, a third color, and a fourth color. For example, the first color may be red, the second color and the fourth color may be green, and the third color may be blue.

[0197] The first sub-emission area SEA1' and the third sub-emission area SEA3' may be arranged in a first direction (or X-axis direction). The second sub-emission area SEA2' and the fourth sub-emission area SEA4' may also be arranged in the first direction (or X-axis direction). The first sub-emission area SEA1' and the second sub-emission area SEA2' may be alternately arranged in a sixth direction DR6. The third sub-emission area SEA3' and the fourth sub-emission area SEA4' may be alternately arranged in the sixth direction DR6.

[0198] Figure 11 is a layout diagram showing Figure 6A an exemplary first sensor line and an exemplary second emission area of a second display area.

[0199] Figure 11 An exemplary embodiment of Figure 10The exemplary embodiment of is different in that: The first sensor line SL1 is formed in a grid pattern between the first sub-emission region SEA1', the second sub-emission region SEA2', the third sub-emission region SEA3', and the fourth sub-emission region SEA4'. For ease of explanation, further description of the previously described elements and technical aspects may be omitted.

[0200] Referring to Figure 11 , the first sensor line SL1 may be disposed between the second sub-emission region SEA2' and the third sub-emission region SEA3', between the first sub-emission region SEA1' and the fourth sub-emission region SEA4', and between the first sub-emission region SEA1' and the second sub-emission region SEA2', thereby forming a grid structure.

[0201] Figure 12 is a layout diagram showing Figure 6A the exemplary first sensor line and the exemplary second emission region of the second display region of .

[0202] Figure 12 The exemplary embodiment of is different from Figure 9 the exemplary embodiment of in that: A plurality of first sensor lines SL1 are disposed between each pair of adjacent second emission regions EA2 in a first direction (or X-axis direction). For ease of explanation, further description of the previously described elements and technical aspects may be omitted.

[0203] Figure 12 shows that four first sensor lines SL1 are disposed between each pair of adjacent second emission regions EA2 in a first direction (or X-axis direction). However, the inventive concept is not limited thereto. For example, according to an exemplary embodiment, the number of first sensor lines SL1 disposed between each pair of adjacent second emission regions EA2 in a first direction (or X-axis direction) may be determined based on whether the first sensor lines SL1 are visible to a user due to the number and density of the second emission regions EA2 in the second display region DA2. The maximum distance in the first direction (or X-axis direction) between the first sensor lines SL1 may be about several tens of micrometers (μm).

[0204] Figure 13 is a layout diagram showing Figure 6A the exemplary first sensor line and the exemplary second emission region of the second display region of .

[0205] Figure 13 The exemplary embodiment of is different from Figure 12 the exemplary embodiment of only in that: Each of the second emission regions EA2 includes as Figure 7a first sub-emission area SEA1', a second sub-emission area SEA2', a third sub-emission area SEA3', and a fourth sub-emission area SEA4' as shown, rather than the first sub-emission area SEA1', the second sub-emission area SEA2', and the third sub-emission area SEA3'. Therefore, for ease of explanation, the detailed description of Figure 13 exemplary embodiments will be omitted.

[0206] Figure 14 is a layout diagram showing an exemplary first sensor line and an exemplary second emission area of a second display area of Figure 6A .

[0207] Figure 14 The exemplary embodiments of Figure 13 differ from the exemplary embodiments of Figure 14 only in that: the first sensor line SL1 is formed in a grid pattern between the first sub-emission area SEA1', the second sub-emission area SEA2', the third sub-emission area SEA3', and the fourth sub-emission area SEA4'. Therefore, for ease of explanation, the detailed description of Figure 14 exemplary embodiments will be omitted.

[0208] Figure 15 is a layout diagram showing an exemplary cut portion and an exemplary third emission area of a third display area of Figure 6A .

[0209] Referring to Figure 15 , a first end of the cut portion CP may be connected to the second display area DA2, and a second end of the cut portion CP may be connected to the second non-display area NDA2. The cut portion CP may be formed in a substantially trapezoidal shape in a plan view. The width of the cut portion CP may gradually increase or decrease from the second display area DA2 to the second non-display area NDA2. Optionally, the cut portion CP may be formed in various other shapes, such as a rectangular shape, a rhombus shape, or a non-quadrilateral polygon shape as examples.

[0210] The cut portion CP may be formed by cutting the display panel 300 with light emitted by a laser. As a result, a first cut gap CG1 may be formed between the cut portions CP. For example, the first cut gap CG1 among the plurality of first cut gaps CG1 may be formed between adjacent cut portions CP among the plurality of cut portions CP. Therefore, the cut portions CP may be spaced apart from each other and the first cut gap CG1 is provided therebetween. The maximum width of the cut portion CP may be larger than the maximum width of the first cut gap CG1. In the exemplary embodiment, the first sensor line SL1 is not provided in the cut portion CP.

[0211] The third emission area EA3 and the second dam DAM2 may be disposed in the cutout portion CP. Each of the third emission areas EA3 may include a first sub-emission area SEA1″, a second sub-emission area SEA2″, and a third sub-emission area SEA3″ that respectively emit light of a first color, a second color, and a third color. For example, the first color may be red, the second color may be green, and the third color may be blue.

[0212] The first sub-emission area SEA1″, the second sub-emission area SEA2″, and the third sub-emission area SEA3″ may be arranged in a first direction (or the X-axis direction). The first sub-emission area SEA1″, the second sub-emission area SEA2″, and the third sub-emission area SEA3″ may have a rectangular shape in a plan view. For example, in the plan view, the first sub-emission area SEA1″, the second sub-emission area SEA2″, and the third sub-emission area SEA3″ may have a rectangular shape having a short side extending in the first direction (or the X-axis direction) and a long side extending in a second direction (or the Y-axis direction) (e.g., a long side that is relatively longer than the short side). However, the inventive concept is not limited thereto. For example, according to an exemplary embodiment, the first sub-emission area SEA1″, the second sub-emission area SEA2″, and the third sub-emission area SEA3″ may be formed in various other shapes (such as, for example, a non-quadrilateral polygon shape, a circular shape, or an elliptical shape) in the plan view. Although Figure 15 it is shown that the first sub-emission area SEA1″, the second sub-emission area SEA2″, and the third sub-emission area SEA3″ have substantially the same area, the inventive concept is not limited thereto. For example, according to an exemplary embodiment, the first sub-emission area SEA1″, the second sub-emission area SEA2″, and the third sub-emission area SEA3″ may have different areas.

[0213] The second dam DAM2 may be disposed along the edge of the third display area DA3. As Figure 18 shown, the second dam DAM2 may be a structure for preventing the organic film from overflowing from the encapsulation layer TFEL. The second dam DAM2 may be provided to surround the third emission area EA3. For example, according to an exemplary embodiment, the second dam DAM2 may completely surround the third emission area EA3.

[0214] Since the third emission area EA3 is disposed in the cutout portion CP as Figure 15 shown, the third display area DA3 may display an image. That is, an image may be displayed even in the first corner portion CS1 to which double curvature strain is applied. Similarly, according to an exemplary embodiment, an image may be displayed even in the second corner portion CS2, the third corner portion CS3, and / or the fourth corner portion CS4.

[0215] Figure 16 is an exemplary layout diagram of a cutout portion of a third display area and an exemplary third emission area showing Figure 6A .

[0216] Figure 16 The exemplary embodiment of Figure 15 differs from the exemplary embodiment of Figure 15 in that each of the third emission areas EA3 includes a first sub - emission area SEA1”, a second sub - emission area SEA2”, a third sub - emission area SEA3” and a fourth sub - emission area SEA4”, instead of a first sub - emission area SEA1”, a second sub - emission area SEA2” and a third sub - emission area SEA3”. The first sub - emission area SEA1”, the second sub - emission area SEA2”, the third sub - emission area SEA3” and the fourth sub - emission area SEA4” are substantially the same as the first sub - emission area SEA1, the second sub - emission area SEA2, the third sub - emission area SEA3 and the fourth sub - emission area SEA4 described in Figure 7 . Thus, for the sake of convenience in explanation, the detailed description of the exemplary embodiment of Figure 16 will be omitted.

[0217] Figure 17 is a cross - sectional view taken along line II - II' of an exemplary embodiment according to the inventive concept of Figure 9 .

[0218] Referring to Figure 17 , the TFT ST' of the TFT layer TFTL and the first sub - emission area SEA1', the second sub - emission area SEA2' and the third sub - emission area SEA3' of the light - emitting element layer EML can be substantially the same as their respective counterparts in Figure 8 . Thus, for the sake of convenience in explanation, their detailed description will be omitted. The TFT ST' can include an active layer ACT', a gate electrode G', a drain electrode D' and a source electrode S', which are substantially the same as their respective counterparts in Figure 8 .

[0219] The first sensor line SL1 can be arranged not to overlap with the first sub - emission area SEA1', the second sub - emission area SEA2' and the third sub - emission area SEA3'. The first sensor line SL1 can be disposed on the third buffer film BF3. The first sensor line SL1 can be formed on the same layer as the first connection portion BE1 of Figure 8 and is formed of the same material as the first connection portion BE1 of Figure 8 .

[0220] The scan driving transistor SDT of the scan driving circuit may include a scan active layer SACT, a scan gate electrode SG, a scan source electrode SS, and a scan drain electrode SD. The scan active layer SACT, the scan gate electrode SG, the scan source electrode SS, and the scan drain electrode SD may be substantially the same as the active layer ACT, the gate electrode G, the source electrode S, and the drain electrode D of the TFT layer TFTL of Figure 8 respectively. Therefore, for ease of explanation, their detailed descriptions will be omitted.

[0221] The scan driving transistor SDT is disposed in the TFT layer TFTL together with the TFT ST' that drives the first sub-emission region SEA1', the second sub-emission region SEA2', and the third sub-emission region SEA3' of the second emission region EA2. Therefore, the scan driving transistor SDT may be disposed in a region where the TFT ST' is not provided to avoid the TFT ST'. In this case, since the first sensor line SL1 is arranged not to overlap with the first sub-emission region SEA1', the second sub-emission region SEA2', and the third sub-emission region SEA3', the scan driving transistor SDT may overlap with the first sensor line SL1 in the third direction (or Z-axis direction).

[0222] The first power supply connection line VSEL may be disposed on the second interlayer insulating film 142. The first power supply connection line VSEL may be formed of the same material as the source electrode S' and the drain electrode D' of the TFT ST' and the source electrode SS and the drain electrode SD of the scan driving transistor SDT.

[0223] The first power supply line VSSL may be disposed on the first organic film 150. The first power supply line VSSL may be formed of the same material as the first connection electrode ANDE1. The first power supply line VSSL may be connected to the first power supply connection line VSEL via a contact hole penetrating the first organic film 150. A first power supply voltage may be applied to the first power supply line VSSL.

[0224] The second light-emitting electrode 173 may be connected to the first power supply line VSSL via a contact hole penetrating the second organic film 160. The first power supply voltage from the first power supply line VSSL may be applied to the second light-emitting electrode 173.

[0225] The encapsulation layer TFEL may include at least one inorganic film that prevents oxygen or moisture from penetrating into the light-emitting element layer EML. In addition, the encapsulation layer TFEL may include at least one organic film that protects the light-emitting element layer EML from foreign substances such as dust. For example, the encapsulation layer TFEL may include a first inorganic film 191 disposed on the second light-emitting electrode 173, an organic film 192 disposed on the first inorganic film 191, and a second inorganic film 193 disposed on the organic film 192.

[0226] The first dam DAM1 can be disposed in the second display area DA2 to prevent the overflow of the organic film 192 of the encapsulation layer TFEL. The first dam DAM1 can include a first sub-dam SDAM1 formed of the same material as the material of the first organic film 150, a second sub-dam SDAM2 formed of the same material as the material of the second organic film 160, and a third sub-dam SDAM3 formed of the same material as the material of the dike 180. Due to the presence of the first dam DAM1, the end of the organic film 192 can be disposed between the first sub-emission area SEA1' and the first dam DAM1, and the first sub-emission area SEA1' is the outermost sub-emission area. The first inorganic film 191 and the second inorganic film 193 can be disposed on the first dam DAM1. The first inorganic film 191 and the second inorganic film 193 can be in contact with each other above the first dam DAM1.

[0227] An additional dam can be further disposed on the outer side of the first dam DAM1 to accommodate the organic film 192 that may have overflowed from the first dam DAM1. In this case, the additional dam can have a structure substantially the same as the structure of the first dam DAM1.

[0228] The first power supply connection line VSEL can be connected to the first power supply outer line VSOL, and the first power supply outer line VSOL can extend to the edge of the second display area DA2. An anti-crack hole CH that penetrates the first power supply outer line VSOL, the first interlayer insulating film 141, the second interlayer insulating film 142, and the gate insulating film 130 can be formed on the edge of the second display area DA2 to prevent the spread of cracks. The first organic film 150 can be formed to cover the anti-crack hole CH. In an exemplary embodiment, the anti-crack hole CH can be omitted.

[0229] As Figure 17 shown, the scan driving transistor SDT of the scan driving circuit can be disposed in an area where the TFT ST' for driving the first sub-emission area SEA1', the second sub-emission area SEA2', and the third sub-emission area SEA3' of the second emission area EA2 is not disposed, so as to avoid the TFT ST'. In this case, since the first sensor line SL1 is disposed so as not to overlap with the first sub-emission area SEA1', the second sub-emission area SEA2', and the third sub-emission area SEA3', the scan driving transistor SDT can overlap with the first sensor line SL1 in the third direction (or Z-axis direction).

[0230] Figure 18 is a cross-sectional view taken along Figure 15 the line III-III'.

[0231] Referring to Figure 18, the TFT "ST" of the TFT layer TFTL and the first sub-emission region SEA1", second sub-emission region SEA2", and third sub-emission region SEA3" of the light-emitting element layer EML can be substantially the same as their respective counterparts in Figure 8 . Thus, for ease of explanation, their detailed descriptions will be omitted. The TFT "ST" can include an active layer ACT", a gate electrode G", a drain electrode D", and a source electrode S", which are substantially the same as their respective counterparts in Figure 8 .

[0232] The first power connection line VSEL, the first power supply line VSSL, the first power supply outer line VSOL, and the crack prevention hole CH' are substantially the same as their respective counterparts in Figure 17 . Thus, for ease of explanation, their detailed descriptions will be omitted.

[0233] In the third display region DA3, the second dam DAM2 can be provided to prevent the overflow of the organic film 192 of the encapsulation layer TFEL. The second dam DAM2 can include a first sub-dam SDAM1' formed of the same material as the material of the first organic film 150, a second sub-dam SDAM2' formed of the same material as the material of the second organic film 160, and a third sub-dam SDAM3' formed of the same material as the material of the bank 180. Due to the presence of the second dam DAM2, the end of the organic film 192 can be disposed between the first sub-emission region SEA1" and the second dam DAM2, and the first sub-emission region SEA1" is the outermost sub-emission region. The first inorganic film 191 and the second inorganic film 193 can be disposed on the second dam DAM2. The first inorganic film 191 and the second inorganic film 193 can be in contact with each other above the second dam DAM2.

[0234] An additional dam can be further provided on the outside of the second dam DAM2 to accommodate the organic film 192 that may have overflowed from the second dam DAM2. In this case, the additional dam can have a structure substantially the same as the structure of the second dam DAM2.

[0235] As shown in Figure 18 , the first sub-emission region SEA1", second sub-emission region SEA2", and third sub-emission region SEA3" of the third emission region EA3 are surrounded by the second dam DAM2. Thus, the first inorganic film 191, the organic film 192, and the second inorganic film 193 of the encapsulation layer TFEL can stably seal the third emission region EA3.

[0236] Figure 19 is a layout diagram showing the first display region, second display region, and third display region, and the second non-display region of a display panel according to an exemplary embodiment of the inventive concept.

[0237] Figure 19 The exemplary embodiment of Figure 6A differs from the exemplary embodiment of

[0238] in that: the second sensor line SL2 is disposed in the cut common pattern CCP' of the substrate SUB. For ease of explanation, further description of the previously described elements and technical aspects may be omitted. Figure 19 Referring to Figure 6A the length of the cut connection portion CBP' connected to the cut portion CP can be smaller than that of Figure 19 the cut connection portion CBP of Figure 6A As a result,

[0239] the width of the cut common pattern CCP' of

[0240] the second sensor line SL2 can be disposed in the cut common pattern CCP' of the second non-display area NDA2 and can be defined as a sensor line connected to some sensor electrodes SE in the first display area DA1. For example, the second sensor line SL2 can include a second driving line TL2 connected to a driving electrode TE disposed in the upper portion of the first display area DA1. Figure 20 and Figure 21 The second sensor line SL2 can be formed in a zigzag shape as shown in Figure 20 and Figure 21 to reduce the strain applied by the double curvature of the first corner portion CS1. Figure 19 and Figure 20 are enlarged layout diagrams of region C of Figure 21 That is,

[0241] and Figure 20 show enlarged views of the second sensor line SL2.

[0242] In an exemplary embodiment, as shown in Figure 21As shown, the second sensor line SL2 can be formed in a meandering shape. In this example, each of the second sensor lines SL2 can include a first bent portion BP1' having a fifth curvature and a second bent portion BP2' having a sixth curvature. In each of the second sensor lines SL2, a group of the first bent portion BP1' and the second bent portion BP2' can be repeatedly arranged. The fifth curvature of the first bent portion BP1' and the sixth curvature of the second bent portion BP2' can be substantially the same or can be different.

[0243] In an exemplary embodiment, the second non-display area NDA2 does not include a cut connection portion CBP', a second cut gap CG2, and a cut common pattern CCP'. In this case, the second sensor line SL2 can be disposed anywhere in the second non-display area NDA2.

[0244] As Figure 19 shown, as the width of the cut common pattern CCP' increases, the second sensor lines SL2 corresponding to some of the first sensor lines SL1 in the second display area DA2 can be disposed in the second non-display area NDA2. That is, some of the first sensor lines SL1 in the second display area DA2 can move to the second non-display area NDA2. Therefore, since the number of the first sensor lines SL1 in the second display area DA2 can be reduced, sufficient space for arranging the second emission area EA2 can be ensured in the second display area DA2, and the resolution of the second display area DA2 can be improved.

[0245] Portions of the second display area DA2 in the second corner portion CS2 to the fourth corner portion CS4, portions of the third display area DA3 in the second corner portion CS2 to the fourth corner portion CS4, and portions of the second non-display area NDA2 in the second corner portion CS2 to the fourth corner portion CS4 can be similar to Figure 19 their respective counterparts. However, the portion of the second non-display area NDA2 in the second corner portion CS2 is different from its Figure 19 counterpart in that the second sensor line SL2 includes a sensing line RL connected to a sensing electrode RE in the first display area DA1 instead of a second driving line TL2. In addition, the portion of the second non-display area NDA2 in the third corner portion CS3 is different from its Figure 19 counterpart in that it does not include the second sensor line SL2. The portion of the second non-display area NDA2 in the fourth corner portion CS4 can be substantially the same as its Figure 19 counterpart.

[0246] Figure 22It is a layout diagram showing the first display area, the second display area, the third display area, and the second non-display area of a display panel according to an exemplary embodiment of the inventive concept.

[0247] Figure 22 The exemplary embodiment of Figure 19 differs from the exemplary embodiment of

[0248] in that: The third sensor line SL3 is disposed in the third display area DA3. For ease of explanation, further description of previously described elements and technical aspects may be omitted. Figure 22 Referring to Figure 23 and Figure 24 the ISP1, ISP2, ISP3, and ISP4 of

[0249] The third display area DA3 may include a third emission area EA3 and a third sensor line SL3, and the third emission area EA3 and the third sensor line SL3 are disposed in the island portion ( Figure 23 and Figure 24 the CNP1, CNP2, CNP3, and CNP4 of Figure 23 and Figure 24 ). The island portion (ISP1, ISP2, ISP3, and ISP4) will be described in further detail below with reference to

[0250] Since the island portion (ISP1, ISP2, ISP3, and ISP4) is formed by laser cutting, the island portion (ISP1, ISP2, ISP3, and ISP4) may be spaced apart from each other. The island portion (ISP1, ISP2, ISP3, and ISP4) may be connected via a connection portion (

[0251] such as Figure 22 The third sensor line SL3 may be disposed in the third display area DA3 and may be defined as a sensor line connected to some sensor electrodes SE in the first display area DA1. For example, the third sensor line SL3 may include a second driving line TL2 connected to a driving electrode TE disposed in the upper portion of the first display area DA1.

[0252] As Figure 22As shown, island portions (ISP1, ISP2, ISP3, and ISP4) can be formed in the third display region DA3 and can be connected via connection portions (CNP1, CNP2, CNP3, and CNP4), thereby arranging third sensor lines SL3 corresponding to some of the first sensor lines SL1 in the second display region DA2. That is, some of the first sensor lines SL1 in the second display region DA2 can be moved to the third display region DA3. Therefore, since the number of the first sensor lines SL1 in the second display region DA2 can be reduced, sufficient space for arranging the second emission region EA2 can be ensured in the second display region DA2, and the resolution of the second display region DA2 can be improved.

[0253] Figure 23 and Figure 24 is a layout diagram showing Figure 22 the exemplary island portions, exemplary connection portions, exemplary third sensor lines, and exemplary third emission region of the third display region.

[0254] Referring to Figure 23 and Figure 24 , the third display region DA3 may further include a first island portion ISP1, a second island portion ISP2, a third island portion ISP3, and a fourth island portion ISP4, as well as a first connection portion CNP1, a second connection portion CNP2, a third connection portion CNP3, and a fourth connection portion CNP4.

[0255] The first island portion ISP1, the second island portion ISP2, the third island portion ISP3, and the fourth island portion ISP4 may be spaced apart from each other. For example, a first cutout portion CUP1 may be provided between the first island portion ISP1 and the second island portion ISP2, and as a result, the first island portion ISP1 may be spaced apart from the second island portion ISP2 in the seventh direction DR7. For example, a second cutout portion CUP2 may be provided between the first island portion ISP1 and the third island portion ISP3, and as a result, the first island portion ISP1 may be spaced apart from the third island portion ISP3 in the eighth direction DR8. For example, the second cutout portion CUP2 may be provided between the second island portion ISP2 and the fourth island portion ISP4, and as a result, the fourth island portion ISP4 may be spaced apart from the second island portion ISP2 in the eighth direction DR8. For example, a third cutout portion CUP3 may be provided between the third island portion ISP3 and the fourth island portion ISP4, and as a result, the fourth island portion ISP4 may be spaced apart from the third island portion ISP3 in the seventh direction DR7.

[0256] The first connection part CNP1, the second connection part CNP2, the third connection part CNP3, and the fourth connection part CNP4 can extend from the first island part ISP1, the second island part ISP2, the third island part ISP3, and the fourth island part ISP4, respectively.

[0257] The first connection part CNP1 can extend from the first island part ISP1 along the seventh direction DR7. The first connection part CNP1 can connect the first island part ISP1 and the second island part ISP2.

[0258] The second connection part CNP2 can extend from the first island part ISP1 along the eighth direction DR8. The second connection part CNP2 can be connected to the island part provided on the upper side of the first island part ISP1.

[0259] The third connection part CNP3 can extend from the first island part ISP1 along the seventh direction DR7. The third connection part CNP3 can be connected to the island part provided on the left side of the first island part ISP1.

[0260] The fourth connection part CNP4 can extend from the first island part ISP1 along the eighth direction DR8. The fourth connection part CNP4 can be connected to the third island part ISP3.

[0261] The third emission region EA3 can be provided in the first island part ISP1, the second island part ISP2, the third island part ISP3, and the fourth island part ISP4. Each of the third emission regions EA3 can include a first sub-emission region SEA1”, a second sub-emission region SEA2”, and a third sub-emission region SEA3” that emit light of a first color, a second color, and a third color, respectively. For example, the first color can be red, the second color can be green, and the third color can be blue.

[0262] The first sub-emission area SEA1", the second sub-emission area SEA2", and the third sub-emission area SEA3" may be arranged in the seventh direction DR7. The third sub-emission area SEA3" may be disposed between the first sub-emission area SEA1" and the second sub-emission area SEA2" in the seventh direction DR7. The first sub-emission area SEA1", the second sub-emission area SEA2", and the third sub-emission area SEA3" may have a rectangular shape in a plan view. For example, in the plan view, the first sub-emission area SEA1", the second sub-emission area SEA2", and the third sub-emission area SEA3" may have a rectangular shape having a short side in the seventh direction DR7 and a long side in the eighth direction DR8 (e.g., a long side relatively longer than the short side). However, the inventive concept is not limited thereto. For example, according to an exemplary embodiment, the first sub-emission area SEA1", the second sub-emission area SEA2", and the third sub-emission area SEA3" may be formed in various other shapes (such as, for example, a non-quadrilateral polygon shape, a circular shape, or an elliptical shape) in the plan view. Although Figure 23 and Figure 24 it is shown that the third sub-emission area SEA3" is larger in size than the first sub-emission area SEA1" and the second sub-emission area SEA2", the inventive concept is not limited thereto.

[0263] The third sensor line SL3 may be disposed in the first island portion ISP1, the second island portion ISP2, the third island portion ISP3, the fourth island portion ISP4, and the first connection portion CNP1, the second connection portion CNP2, the third connection portion CNP3, and the fourth connection portion CNP4. In an exemplary embodiment, the third sensor line SL3 does not overlap with the first sub-emission area SEA1", the second sub-emission area SEA2", and the third sub-emission area SEA3". That is, in an exemplary embodiment, the third sensor line SL3 does not overlap with the third emission area EA3. The third sensor line SL3 may be disposed between the first sub-emission area SEA1" and the third sub-emission area SEA3" and between the second sub-emission area SEA2" and the third sub-emission area SEA3". The third sensor line SL3 may be formed in an amorphous grid form.

[0264] Since the third display area DA3 is disposed in the first corner portion CS1, the first island portion ISP1, the second island portion ISP2, the third island portion ISP3, and the fourth island portion ISP4 as shown in Figure 24 may be spaced apart from each other due to strain caused by double curvature.

[0265] Since as shown in Figure 23 and Figure 24The third emission area EA3 shown in the figure is provided in the first island part ISP1, the second island part ISP2, the third island part ISP3, and the fourth island part ISP4, so that the third display area DA3 can display an image. That is, an image can be displayed even in the first corner part CS1 to which biaxial curvature strain is applied.

[0266] In addition, since the island parts (ISP1, ISP2, ISP3, and ISP4) are connected to each other via the connection parts (CNP1, CNP2, CNP3, and CNP4) and the third sensor line SL3 is provided in the connection parts (CNP1, CNP2, CNP3, and CNP4), some of the first sensor lines SL1 in the second display area DA2 can move to the third display area DA3. Therefore, since the number of the first sensor lines SL1 in the second display area DA2 can be reduced, sufficient space for arranging the second emission area EA2 can be ensured in the second display area DA2, and the resolution of the second display area DA2 can be improved.

[0267] Figure 25 is a cross-sectional view taken along the line IV-IV' of an exemplary embodiment according to the inventive concept. Figure 23 of the display device.

[0268] Referring to Figure 25 , the TFT ST” of the TFT layer TFTL and the first sub-emission area SEA1”, the second sub-emission area SEA2”, and the third sub-emission area SEA3” of the light-emitting element layer EML can be substantially the same as their respective counterparts in Figure 18 . Therefore, for ease of explanation, their detailed descriptions will be omitted.

[0269] The third sensor line SL3 can be arranged not to overlap with the first sub-emission area SEA1”, the second sub-emission area SEA2”, and the third sub-emission area SEA3”. The third sensor line SL3 can be provided on the third buffer film BF3. The third sensor line SL3 can be formed on the same layer as the first connection part BE1 in Figure 8 and be formed of the same material as the material of the first connection part BE1 in Figure 8 .

[0270] In the display device according to the exemplary embodiment of the inventive concept, the third display area capable of displaying an image is provided in the corner part of the display device, and the second display area including the emission area is additionally provided between the first display area and the third display area in the forward part of the display device. Therefore, when images are displayed in the first display area and the third display area, it is possible to prevent the non-display area between the first display area and the third display area from being visible to the user.

[0271] In a display device according to an exemplary embodiment of the inventive concept, since sensor lines are disposed in a non-display area outside a third display area, the number of sensor lines disposed in a second display area located between a first display area and the third display area may be reduced. As a result, sufficient space for arranging a second emission area may be ensured in the second display area, and the resolution of the second display area may be improved.

[0272] In a display device according to an exemplary embodiment of the inventive concept, since sensor lines are disposed in the third display area, the number of sensor lines disposed in a second display area located between a first display area and the third display area may be reduced. As a result, sufficient space for arranging a second emission area may be ensured in the second display area, and the resolution of the second display area may be improved.

[0273] Although the inventive concept has been specifically shown and described with reference to exemplary embodiments of the inventive concept, those of ordinary skill in the art will understand that various changes in form and detail may be made thereto without departing from the spirit and scope of the inventive concept as set forth in the claims.
