[0087] Hereinafter, specific embodiments will be described with reference to the drawings.

[0088] is a perspective view of a display device according to an embodiment.

[0089] Figure 1 is an exploded perspective view of a display device according to an embodiment. Figure 2 is a cross-sectional view showing an example of I-I' of Figure 3 showing Figure 1 of.

[0090] Referring to Figures 1 to 3 , the display device 10 according to an embodiment is a device for displaying moving images or still images. The display device 10 can be used as a display screen for various products such as portable electronic devices such as mobile phones, smart phones, tablet personal computers (PCs), smart watches, watch phones, mobile communication terminals, electronic notebooks, e-books, portable multimedia players (PMPs), navigation devices, and ultra-mobile PCs (UMPCs) and various products such as televisions, notebook computers, monitors, billboards, and Internet of Things (IoT) devices.

[0091] For example, the display device 10 according to an embodiment can be used as a displayable speaker, which has speaker holes SPH formed in the surface SF1 as shown in Figure 52 and displays an image on other surfaces. Although the speaker holes SPH are formed only in the surface SF1 in Figure 52 , the embodiments of the present disclosure are not limited thereto. The speaker holes SPH can also be formed in multiple surfaces of the display device 10. In addition, the speaker holes SPH can be formed in the entire surface SF1 of the display device 10 as shown in Figure 52 , or can be formed only in a part of the surface SF1.

[0092] As shown in Figures 1 to 3 , the display device 10 according to an embodiment can include a cover window 100, a touch sensing device 200, a touch circuit board 210, a touch driver 220, a display panel 300, a display circuit board 310, a display driver 320, a panel guiding member 500, a bottom frame 600, and a main circuit board 700.

[0093] In this specification, "above", "top", and "upper surface" refer to the direction in which the cover window 100 is disposed with respect to the display panel 300, that is, the Z-axis direction, and "below", "bottom", and "lower surface" refer to the direction in which the panel guiding member 500 is disposed with respect to the display panel 300, that is, the direction opposite to the Z-axis direction. In addition, "left", "right", "up", and "down" refer to the directions when viewing the display panel 300 in a plan view. For example, "left" refers to the direction opposite to the X-axis direction, "right" refers to the X-axis direction, "up" refers to the Y-axis direction, and "down" refers to the direction opposite to the Y-axis direction.

[0094] The display device 10 can display an image on the upper surface DPS1, the left side surface DSS1, the right side surface DSS2, the upper side surface DSS3, and the lower side surface DSS4. The left side surface DSS1 of the display device 10 can extend from the first long side DLS1 of the upper surface DPS1, the right side surface DSS2 can extend from the second long side DLS2 of the upper surface DPS1, the upper side surface DSS3 can extend from the first short side DS1 of the upper surface DPS1, and the lower side surface DSS4 can extend from the second short side DS2 of the upper surface DPS1. The first short side DS1 and the second short side DS2 can be disposed in the first direction (X-axis direction), and the first long side DLS1 and the second long side DLS2 can be disposed in the second direction (Y-axis direction) intersecting the first direction (X-axis direction).

[0095] When viewed in a plan view, the upper surface DPS1, the left side surface DSS1, the right side surface DSS2, the upper side surface DSS3, and the lower side surface DSS4 are rectangular, but embodiments of the present disclosure are not limited thereto. When viewed in a plan view, the upper surface DPS1, the left side surface DSS1, the right side surface DSS2, the upper side surface DSS3, and the lower side surface DSS4 may also be formed into other polygonal shapes or circular or elliptical shapes.

[0096] When viewed in a plan view, the first corner surface DC1 between the left side surface DSS1 and the upper side surface DSS3, the second corner surface DC2 between the left side surface DSS1 and the lower side surface DSS4, the third corner surface DC3 between the right side surface DSS2 and the upper side surface DSS3, and the fourth corner surface DC4 between the right side surface DSS2 and the lower side surface DSS4 may be rounded with a predetermined curvature or may be at a right angle. Additionally, in Figure 1 the left side surface DSS1, the right side surface DSS2, the upper side surface DSS3, and the lower side surface DSS4 bend perpendicularly from the upper surface DPS1, but embodiments of the present disclosure are not limited thereto.

[0097] The cover window 100 may be disposed on the upper surface and the side surfaces of the display panel 300 to cover the upper surface and the side surfaces of the display panel 300. Accordingly, the cover window 100 may serve to protect the upper surface and the side surfaces of the display panel 300. As Figure 3 shown in, the cover window 100 may be attached to the touch sensing device 200 by a first adhesive member 910. The first adhesive member 910 may be an optically clear adhesive film (OCA) or an optically clear resin (OCR).

[0098] The cover window 100 may be made of glass, sapphire, and / or plastic. The cover window 100 may be formed to be rigid or flexible. The cover window 100 may include a light-transmitting portion corresponding to the display area of the display panel 300 and a light-blocking portion corresponding to the non-display area of the display panel 300. The light-blocking portion may include an opaque material such as a black dye. Additionally, a pattern that may be displayed to the user when no image is being displayed may be formed on the upper surface of the light-blocking portion. For example, a company logo such as "SAMSUNG" or various characters may be formed on the upper surface of the light-blocking portion.

[0099] The touch sensing device 200 may be disposed between the cover window 100 and the display panel 300. The touch sensing device 200 may be disposed on the upper surface and the side surfaces of the display panel 300. Accordingly, a user's touch may be sensed on the upper surface DPS1, the left side surface DSS1, the right side surface DSS2, the upper side surface DSS3, and the lower side surface DSS4 of the display device 10.

[0100] The touch sensing device 200 can be attached to the lower surface of the cover window 100 by a first adhesive member 910 as shown in Figure 3 . A polarizing film for preventing a reduction in visibility caused by reflection of external light can be added between the cover window 100 and the touch sensing device 200. In this case, the touch sensing device 200 can be attached to the lower surface of the polarizing film, and the polarizing film can be attached to the lower surface of the cover window 100 by the first adhesive member 910.

[0101] The touch sensing device 200 is a device for sensing a user's touch position and can be implemented as a capacitive type such as a self-capacitance type or a mutual-capacitance type. When the touch sensing device 200 is implemented as the self-capacitance type, it may include only touch driving electrodes, but when it is implemented as the mutual-capacitance type, it may include touch driving electrodes and touch sensing electrodes. The case where the touch sensing device 200 is implemented as the mutual-capacitance type will be mainly described below.

[0102] The touch sensing device 200 can include a separate substrate and touch driving electrodes provided on the separate substrate. In this case, the touch sensing device 200 can be attached to the thin film encapsulation layer of the display panel 300 by a second adhesive member 920 as shown in Figure 3 . The second adhesive member 920 can be OCA or OCR. Alternatively, the touch sensing device 200 can be integrally formed with the display panel 300. In this case, the touch driving electrodes and touch sensing electrodes of the touch sensing device 200 can be formed on the thin film encapsulation layer of the display panel 300.

[0103] The touch circuit board 210 can be attached to one side surface of the touch sensing device 200. Specifically, one side of the touch circuit board 210 can be attached to pads provided on one side surface of the touch sensing device 200 by using an anisotropic conductive film. In addition, a touch connection portion can be provided on the other side of the touch circuit board 210 and can be connected to the touch connector of the display circuit board 310. The touch circuit board can be a flexible printed circuit board.

[0104] The touch driver 220 can transmit a touch driving signal to the touch driving electrodes of the touch sensing device 200, detect a sensing signal from the touch sensing electrodes of the touch sensing device 200, and calculate the user's touch position by analyzing the sensing signal. The touch driver 220 can be formed as an integrated circuit and mounted on the touch circuit board 210.

[0105] The display panel 300 can be disposed below the touch sensing device 200. The display panel 300 can be attached to the lower surface of the touch sensing device 200 by a second adhesive member 920 as shown in Figure 3 .

[0106] The display panel 300 may be a light-emitting display panel including light-emitting elements. For example, the display panel 300 may be an organic light-emitting display panel using an organic light-emitting diode as a light-emitting element, a micro light-emitting diode (LED) display panel using a micro LED as a light-emitting element, a quantum dot organic light-emitting display panel using a quantum dot and an organic light-emitting diode as light-emitting elements, or an inorganic light-emitting display panel using an inorganic semiconductor as a light-emitting element. The case where the display panel 300 is an organic light-emitting display panel as shown below will be mainly described. Figure 14 as shown.

[0107] The display panel 300 may include a substrate, a thin-film transistor layer disposed on the substrate, a light-emitting element layer, and a thin-film encapsulation layer.

[0108] Since the display panel 300 is implemented as flexible, the display panel 300 may be made of plastic. In this case, the substrate may include a flexible substrate and a support substrate. Since the support substrate is designed to support the flexible substrate, the support substrate may have less flexibility than the flexible substrate. Each of the flexible substrate and the support substrate may include a polymer material having flexibility.

[0109] The thin-film transistor layer is disposed on the substrate. The thin-film transistor layer may include scan lines, data lines, and thin-film transistors. Each of the thin-film transistors includes a gate electrode, a semiconductor layer, and a source electrode and a drain electrode. When the scan driver is directly formed on the substrate, the scan driver may be formed together with the thin-film transistor layer.

[0110] The light-emitting element layer is disposed on the thin-film transistor layer. The light-emitting element layer includes an anode, a light-emitting layer, a cathode, and a bank. The light-emitting layer may include an organic light-emitting layer containing an organic material. For example, the light-emitting layer may include a hole injection layer, a hole transport layer, an organic light-emitting layer, an electron transport layer, and an electron injection layer. The hole injection layer and the electron injection layer may be omitted. When a voltage is applied to the anode and the cathode, holes and electrons move to the organic light-emitting layer through the hole transport layer and the electron transport layer, respectively, and are combined together in the organic light-emitting layer to emit light. The light-emitting element layer may be a pixel array layer in which pixels are formed. Therefore, the region in which the light-emitting element layer is formed may be defined as a display region for displaying an image. The region around the display region may be defined as a non-display region.

[0111] The thin-film encapsulation layer is disposed on the light-emitting element layer. The thin-film encapsulation layer prevents oxygen or moisture from penetrating into the light-emitting element layer. The thin-film encapsulation layer may include at least one inorganic layer and at least one organic layer.

[0112] The display circuit board 310 may be attached to either side surface of the display panel 300. Specifically, one side of the display circuit board 310 may be attached to pads provided on either side surface of the display panel 300 by using an anisotropic conductive film. The display circuit board 310 may be bent under the display panel 300. The touch circuit board 210 may also be bent under the display panel 300. Accordingly, the touch circuit board 210 may overlap with the display circuit board 310. Accordingly, a touch connection portion provided at an end of the touch circuit board 210 may be connected to a touch connector of the display circuit board 310.

[0113] The display driver 320 outputs signals and voltages for driving the display panel 300 through the display circuit board 310. The display driver 320 may be formed as an integrated circuit and mounted on the display circuit board 310.

[0114] The panel lower member 400 may be provided under the display panel 300 as Figure 12 shown. The panel lower member 400 may be attached to the lower surface of the display panel 300 by a third adhesive member 930. The third adhesive member 930 may be an OCA, an OCR, or a pressure-sensitive adhesive (PSA).

[0115] The panel lower member 400 may include at least one of a light absorption member for absorbing light incident from the outside, a buffer member for absorbing external shocks, a heat dissipation member for effectively dissipating heat of the display panel 300, and a light-blocking layer for blocking light incident from the outside.

[0116] The light absorption member may be provided under the display panel 300. The light absorption member blocks the transmission of light to prevent components provided under the light absorption member from being viewed from above the display panel 300. The light absorption member may include a light absorption material such as a black pigment or dye.

[0117] The buffer member may be provided under the light absorption member. The buffer member absorbs external shocks to prevent the display panel 300 from being damaged. The buffer member may be composed of a single layer or multiple layers. For example, the buffer member may be made of a polymer resin such as polyurethane, polycarbonate, polypropylene, or polyethylene, or may be made of an elastic material such as a sponge formed by foaming rubber, a polyurethane-based material, or an acrylic-based material. The buffer member may be a cushion layer.

[0118] The heat dissipation member may be provided under the buffer member. The heat dissipation member may include: a first heat dissipation layer containing graphite or carbon nanotubes; and a second heat dissipation layer formed of a metal thin film (such as copper, nickel, ferrite, or silver) capable of shielding electromagnetic waves and having a high thermal conductivity.

[0119] A panel guiding member 500 for bending and fixing a side surface of the display panel 300 may be disposed below the panel lower member 400. The panel guiding member 500 may be disposed below the lower surface and the side surface of the display panel 300.

[0120] The panel guiding member 500 may be made of a rigid plastic to support the display panel 300. For example, the panel guiding member 500 may be made of a plastic such as polycarbonate. The panel guiding member 500 may be attached to the lower surface of the display panel 300 by a fourth adhesive member 940 as Figure 3 shown. The fourth adhesive member 940 may be an OCA, an OCR, or a PSA.

[0121] Since each of the cover window 100, the touch sensing device 200, the display panel 300, the panel lower member 400, and the panel guiding member 500 does not include a lower surface as Figure 3 shown, a space may be formed between the panel guiding member 500 and the bottom frame 600. The main circuit board 700 and the battery 730 may be disposed in the space between the panel guiding member 500 and the bottom frame 600.

[0122] The main circuit board 700 may be a printed circuit board or a flexible printed circuit board. The main circuit board 700 may include a main processor 710 and a camera device 720. The main processor 710 may be disposed on the lower surface of the main circuit board 700 facing the bottom frame 600. In addition, the camera device 720 may be disposed on both the upper surface and the lower surface of the main circuit board 700.

[0123] The main processor 710 may control all functions of the display device 10. For example, the main processor 710 may output image data to the display driver 320 of the display circuit board 310 so that the display panel 300 may display an image. In addition, the main processor 710 may receive touch data from the touch driver 220, determine the user's touch position, and then execute an application indicated by an icon displayed at the user's touch position. In addition, the main processor 710 may receive pressure sensing data from the touch driver 220 or the pressure sensing unit, and may execute an application indicated by an icon displayed at the user's touch position according to the pressure sensing data. In addition, the main processor 710 may be controlled to implement haptic feedback by vibrating a vibration generating device according to the pressure sensing data. The main processor 710 may be an application processor, a central processing unit, or a system-on-chip formed as an integrated circuit.

[0124] The camera device 720 processes image frames such as still images or moving images obtained by the image sensor in the camera mode, and outputs the processed image frames to the main processor 710. The battery 730 provides power required for the display device 10.

[0125] In addition, the main circuit board 700 may be further equipped with a mobile communication module that can send wireless signals to or receive wireless signals from at least one of a base station, an external terminal, and a server through a mobile communication network. According to the sending / receiving of text / multimedia messages, the wireless signals may include voice signals, video call signals, or various types of data. Additionally, a sound output device such as a speaker capable of outputting sound may be further installed on the main circuit board 700.

[0126] The bottom frame 600 may be disposed below the panel guiding member 500. The bottom frame 600 may include plastic, metal, or both plastic and metal. The bottom frame 600 may form the bottom exterior of the display device 10.

[0127] A waterproof member 610 may be disposed on the edge of the bottom frame 600. The waterproof member 610 may join the side surface of the display panel 300 to the upper surface of the bottom frame 600. Thus, according to Figure 2 and Figure 3 the embodiment shown in, the waterproof member 610 may prevent moisture or dust from penetrating between the display panel 300 and the bottom frame 600. That is, a waterproof and dustproof display device 10 may be provided.

[0128] A camera hole CMH into which the camera device 720 is inserted and protrudes outward may be formed in the bottom frame 600. The position of the camera device 720 and the position of the camera hole CMH corresponding to the camera device 720 are not limited to Figure 2 the embodiment shown in.

[0129] Figure 4 is an exploded view of a display panel according to an embodiment. Figures 5 to 17 is Figure 4 the perspective view, plan view, bottom view, front view, rear view, left side view, and right side view of the display panel of.

[0130] Referring to Figure 4 and Figures 5 to 17 , the display panel 300 according to an embodiment may include a first flat surface PS1, a first side surface SS1, a second side surface SS2, a first extended surface ES1, and a second extended surface ES2.

[0131] When viewed in a plan view, the first flat surface PS1, the first side surface SS1, the second side surface SS2, the first extension surface ES1, and the second extension surface ES2 are rectangular, but embodiments of the present disclosure are not limited thereto. When viewed in a plan view, the first flat surface PS1, the first side surface SS1, the second side surface SS2, the first extension surface ES1, and the second extension surface ES2 may also be formed into other polygonal shapes or circular or elliptical shapes.

[0132] The first flat surface PS1 may include a first side S11, a second side S12, a third side S13, and a fourth side S14. The first side S11 and the second side S12 of the first flat surface PS1 may be longer than the third side S13 and the fourth side S14 of the first flat surface PS1. The first side S11 and the second side S12 of the first flat surface PS1 may be parallel to each other, and the third side S13 and the fourth side S14 may be parallel to each other. Although the first side S11 and the second side S12 of the first flat surface PS1 have the same length in Figure 4 the first flat surface PS1, the first side S11 and the second side S12 of the first flat surface PS1 may also have different lengths. Additionally, although the third side S13 and the fourth side S14 of the first flat surface PS1 have the same length, the third side S13 and the fourth side S14 of the first flat surface PS1 may also have different lengths. As shown in Figure 5 and Figure 6 the first flat surface PS1 may be the upper surface of the display panel 300. The first flat surface PS1 may overlap with the upper surface DPS1 of the cover window 100.

[0133] The first side surface SS1 may extend from the first side S11 of the first flat surface PS1. The first side surface SS1 may be bent from the first side S11 of the first flat surface PS1 in the third direction (Z-axis direction). As shown in Figure 5 and Figure 10 the first side surface SS1 may be the left side surface of the display panel 300. The first side surface SS1 may include a first side S21, a second side S22, and a third side S23, and may share the first side S11 of the first flat surface PS1 as one side. The first side S21 and the second side S22 of the first side surface SS1 may be parallel to each other and may be shorter than the third side S23 of the first side surface SS1. Although the first side S21 and the second side S22 of the first side surface SS1 have the same length in Figure 4 the first side surface SS1, the first side S21 and the second side S22 of the first side surface SS1 may also have different lengths. The first side surface SS1 may overlap with the left side surface DSS1 of the cover window 100.

[0134] The second side surface SS2 may extend from the second edge S12 of the first flat surface PS1. The second side surface SS2 may be curved from the second edge S12 of the first flat surface PS1 in the third direction (Z-axis direction). As Figure 5 and Figure 11 shown, the second side surface SS2 may be the right side surface of the display panel 300. The second side surface SS2 may include a first edge S31, a second edge S32, and a third edge S33, and may share the second edge S12 of the first flat surface PS1 as one side with the first flat surface PS1. The first edge S31 and the second edge S32 of the second side surface SS2 may be parallel to each other and may be shorter than the third edge S33 of the second side surface SS2. Although the first edge S31 and the second edge S32 of the second side surface SS2 have the same length in Figure 4 they may also have different lengths. The second side surface SS2 may overlap with the right side surface DSS2 of the cover window 100.

[0135] The first extension surface ES1 may extend from the first edge S21 of the first side surface SS1. The first extension surface ES1 may be curved from the first edge S21 of the first side surface SS1 in the first direction (X-axis direction). As Figure 5 and Figure 8 shown, the first extension surface ES1 may be the upper side surface of the display panel 300. The first extension surface ES1 may include a first edge S41, a second edge S42, and a third edge S43, and may share the first edge S21 of the first side surface SS1 as one side with the first side surface SS1. The first edge S41 and the second edge S42 of the first extension surface ES1 may be parallel to each other and may be longer than the third edge S43 of the first extension surface ES1. The first extension surface ES1 may overlap with the upper side surface DSS3 of the cover window 100.

[0136] The second extension surface ES2 may extend from the first edge S31 of the second side surface SS2. The second extension surface ES2 may be curved from the first edge S31 of the second side surface SS2 in the first direction (X-axis direction). As Figure 5 and Figure 9 shown, the second extension surface ES2 may be the lower side surface of the display panel 300. The second extension surface ES2 may include a first edge S51, a second edge S52, and a third edge S53, and may share the first edge S21 of the second side surface SS2 as one side with the second side surface SS2. The first edge S51 and the second edge S52 of the second extension surface ES2 may be parallel to each other and may be longer than the third edge S53 of the second extension surface ES2. The second extension surface ES2 may overlap with the lower side surface DSS4 of the cover window 100.

[0137] The first extended surface ES1 is curved in a first direction (the X-axis direction) from a first edge S21 of the first side surface SS1. Thus, a first edge S41 of the first extended surface ES1 can face a third edge S13 of the first flat surface PS1, and a third edge S43 of the first extended surface ES1 can face a second edge S32 of the second side surface SS2. In this case, the length of the first edge S41 of the first extended surface ES1 and the length of the third edge S13 of the first flat surface PS1 can be substantially the same, and the length of the third edge S43 of the first extended surface ES1 and the length of the second edge S32 of the second side surface SS2 can be substantially the same. Additionally, there may be a slight gap between the first edge S41 of the first extended surface ES1 and the third edge S13 of the first flat surface PS1 and between the third edge S43 of the first extended surface ES1 and the second edge S32 of the second side surface SS2. Alternatively, the first edge S41 of the first extended surface ES1 and the third edge S13 of the first flat surface PS1 can be in contact with each other, and the third edge S43 of the first extended surface ES1 and the second edge S32 of the second side surface SS2 can be in contact with each other.

[0138] The second extended surface ES2 is curved in a first direction (the X-axis direction) from a first edge S31 of the second side surface SS2. Thus, a first edge S51 of the second extended surface ES2 can face a fourth edge S14 of the first flat surface PS1, and a third edge S53 of the second extended surface ES2 can face a second edge S22 of the first side surface SS1. In this case, the length of the first edge S51 of the second extended surface ES2 and the length of the fourth edge S14 of the first flat surface PS1 can be substantially the same, and the length of the third edge S53 of the second extended surface ES2 and the length of the second edge S22 of the first side surface SS1 can be substantially the same. Additionally, there may be a slight gap between the first edge S51 of the second extended surface ES2 and the fourth edge S14 of the first flat surface PS1 and between the third edge S53 of the second extended surface ES2 and the second edge S22 of the first side surface SS1. Alternatively, the first edge S51 of the second extended surface ES2 and the fourth edge S14 of the first flat surface PS1 can be in contact with each other, and the third edge S53 of the second extended surface ES2 and the second edge S22 of the first side surface SS1 can be in contact with each other.

[0139] The scan driver 330 may output scan signals to scan lines. The scan driver 330 may be disposed on the first flat surface PS1 and the first side surface SS1. The scan driver 330 may be disposed adjacent to the fourth side S14 of the first flat surface PS1 and the second side S22 of the first side surface SS1. The scan driver 330 may also be disposed on the second side surface SS2, in which case the scan driver 330 may be disposed adjacent to the first side S31 of the second side surface SS2.

[0140] The display circuit board 310 may be disposed on a display pad that is disposed adjacent to the first side S21 of the first side surface SS1. The display circuit board 310 may be electrically connected to data lines through the display pad. The display driver 320 of the display circuit board 310 may output data voltages to the data lines.

[0141] will be described in detail later with reference to Figures 5 to 11 the scan lines connected to the scan driver 330 and the display pads and data lines connected to the display circuit board 310.

[0142] According to Figure 4 and Figures 5 to 11 the embodiment shown in, the display panel 300 may include a first flat surface PS1, a first side surface SS1, a second side surface SS2, a first extension surface ES1, and a second extension surface ES2. Accordingly, the display panel 300 has pixels disposed not only on the first flat surface PS1 but also on the first side surface SS1, the second side surface SS2, the first extension surface ES1, and the second extension surface ES2. Accordingly, an image may be displayed on the first side surface SS1, the second side surface SS2, the first extension surface ES1, and the second extension surface ES2. That is, the display panel 300 may display an image on the upper surface and side surfaces of the display panel 300.

[0143] Figure 12 is a plan view exemplarily showing in detail Figure 4 the first flat surface, the first side surface, and the second side surface. Figure 5 is a plan view exemplarily showing in detail Figure 4 the first extension surface. Figure 14 is a plan view exemplarily showing in detail Figure 4 the second extension surface.

[0144] Refer to Figures 12 to 14, the display panel 300 may include scan lines SL, data lines DL, pixels P, display pads DP, and a scan driver 330. The scan lines SL, data lines DL, and pixels P may be disposed on a first flat surface PS1, a first side surface SS1, a second side surface SS2, a first extended surface ES1, and a second extended surface ES2 of the display panel 300. The display pads DP may be disposed on the first side surface SS1 of the display panel 300. The scan driver 330 may be disposed on the first flat surface PS1 and the first side surface SS1 of the display panel 300.

[0145] The display panel 100 may include a display area in which pixels are formed to display an image and a non-display area NDA positioned around the display area DA. The non-display area NDA may be defined as an area extending from the outside of the display area DA to the edge of the display panel 100. A black matrix may be formed in the non-display area NDA. The non-display area NDA may overlap with a light-blocking portion of the cover window 100. Accordingly, the non-display area NDA may be covered by the light-blocking portion of the cover window 100 such that the non-display area NDA is not visible from the outside.

[0146] The scan lines SL, data lines DL, and pixels P may be disposed in the display area DA, and the display pads DP and the scan driver 330 may be disposed in the non-display area NDA.

[0147] The scan lines SL may be formed to be parallel to each other in a second direction (Y-axis direction), and the data lines DL may be formed to be parallel to each other in a first direction (X-axis direction) intersecting the second direction (Y-axis direction). The scan lines SL may be connected to the scan driver 330, and the data lines DL may be connected to the display pads DP.

[0148] The pixels P may be formed in a matrix form. Each of the pixels P may be connected to at least any one of the scan lines SL and any one of the data lines DL. Each of the pixels P may include a thin film transistor including a driving transistor and at least one switching transistor, an organic light emitting diode, and a capacitor. When a scan signal is transmitted from the scan line SL, each of the pixels P may receive a data voltage of the data line DL, and as the driving transistor supplies a driving current to the organic light emitting diode according to the data voltage applied to the gate electrode, each of the pixels P may emit light.

[0149] Figure 12The pixel P shown may be a sub-pixel, and a plurality of pixels P may be defined as a pixel group capable of displaying white. For example, three adjacent pixels P in the first direction (X-axis direction) or the second direction (Y-axis direction) may be defined as a pixel group. In this case, among the three pixels P, the first pixel may display light of a first color, the second pixel may display light of a second color, and the third pixel may display light of a third color. The light of the first color may be red light, the light of the second color may be green light, and the light of the third color may be blue light. However, the embodiments of the present disclosure are not limited thereto. Alternatively, when viewed in a plan view, four adjacent rectangular pixels P may be defined as a pixel group. In this case, among the four pixels P, the first pixel may display light of a first color, the second pixel may display light of a second color, the third pixel may display light of a third color, and the fourth pixel may display light of a fourth color. The light of the first color may be red light, the light of the second color may be green light, the light of the third color may be blue light, and the light of the fourth color may be white light or green light. However, the embodiments of the present disclosure are not limited thereto.

[0150] The scan line SL may include a first scan line SL1 provided on the first flat surface PS1, a second scan line SL2 provided on the first side surface SS1 and the first extended surface ES1, and a third scan line SL3 provided on the second side surface SS2 and the second extended surface ES2. The first scan line SL1, the second scan line SL2, and the third scan line SL3 may extend in the second direction (Y-axis direction).

[0151] Each of the first scan lines SL1 may be connected to a pixel P provided on the first flat surface PS1. The scan line SL extends in the second direction (Y-axis direction), the first extended surface ES1 extends from the first side surface SS1 in the second direction (Y-axis direction), and the second extended surface ES2 extends from the second side surface SS2 in the second direction (Y-axis direction). Therefore, the second scan line SL2 may be connected to the pixel P on the first side surface SS1 and the pixel P on the first extended surface ES1. The third scan line SL3 may be connected to the pixel P on the second side surface SS2 and the pixel P on the second extended surface ES2.

[0152] The data line DL may include: a first data line DL1 provided on the first side surface SS1, the first flat surface PS1, and the second side surface SS2; a second data line DL2 provided on the first side surface SS1 and the first extended surface ES1; and a third data line DL3 provided on the first side surface SS1, the first flat surface PS1, the second side surface SS2, and the second extended surface ES2.

[0153] Each of the first data lines DL1 can extend in the first direction (X-axis direction) and can be connected to the pixels P provided on the first side surface SS1, the first flat surface PS1, and the second side surface SS2.

[0154] Each of the second data lines DL2 can be connected to the pixels P provided on the first extended surface ES1. As Figure 5 shown, each of the second data lines DL2 can extend in the second direction (Y-axis direction), bend in the first direction (X-axis direction) starting from the second direction (Y-axis direction), and then extend in the first direction (X-axis direction). In this case, the second data lines DL2 can be arranged parallel to the second scan lines SL2 on the first side surface SS1 and can intersect the second scan lines SL2 on the first extended surface ES1. Alternatively, each of the second data lines DL2 can extend in the first direction (X-axis direction), bend in the second direction (Y-axis direction) starting from the first direction (X-axis direction), and then extend in the second direction (Y-axis direction). In this case, the second data lines DL2 can be arranged parallel to the second scan lines SL2 on the first extended surface ES1.

[0155] Each of the third data lines DL3 can be connected to the pixels P provided on the second extended surface ES2. As Figure 14 shown, each of the third data lines DL3 can extend in the second direction (Y-axis direction), bend in the first direction (X-axis direction) starting from the second direction (Y-axis direction) at a position adjacent to the second side S22 of the first side surface SS1, extend in the first direction (X-axis direction), extend in the second direction (Y-axis direction) on the second side surface SS2, bend in the first direction (X-axis direction) starting from the second direction (Y-axis direction) on the second extended surface ES2, and then extend in the first direction (X-axis direction). In this case, the third data lines DL3 can intersect the second scan lines SL1 on the first flat surface PS1. Additionally, the third data lines DL3 can be arranged between the scan driver 330 and the pixels P on the first flat surface PS1, or can be arranged between the scan driver 330 and the fourth side S14 of the first flat surface PS1.

[0156] The display pad DP can be arranged adjacent to the third side S23 of the first side surface SS1. The display pad DP can be connected to the data line DL, and the scan control line SCL is connected to the scan driver 330. Although in Figure 12 the scan driver 330 is connected to one scan control line SCL, the scan driver 330 can be connected to multiple scan control lines SCL.

[0157] The display pad DP can be attached to the lead terminal of the display circuit board 310 by using an anisotropic conductive film. Therefore, the display pad DP can be electrically connected to the display driver 320 of the display circuit board 310. Accordingly, the scan control signal of the display driver 320 can be supplied to the scan control line SCL through the display pad DP, and the data signal can be supplied to the data line DL through the display pad DP.

[0158] The scan driver 330 can be arranged adjacent to the fourth side S14 of the first flat surface PS1. The scan driver 330 can be connected to the scan line SL. The scan driver 330 can generate a scan signal according to the scan control signal supplied through the scan control line SCL, and can supply the scan signal to the scan line SL.

[0159] In Figure 5 and Figure 14 , for ease of description, an example is shown in which the pixels P are arranged in two rows in the second direction (Y-axis direction) on each of the first side surface SS1, the second side surface SS2, the first extension surface ES1, and the second extension surface ES2. However, embodiments of the present disclosure are not limited thereto.

[0160] According to Figures 12 to 14 the embodiment shown in, the display panel 300 has pixels disposed not only on the first flat surface PS1 but also on the first side surface SS1, the second side surface SS2, the first extension surface ES1, and the second extension surface ES2. Accordingly, an image can be displayed on the first side surface SS1, the second side surface SS2, the first extension surface ES1, and the second extension surface ES2.

[0161] Since the first extension surface ES1 extends long in the second direction (Y-axis direction), it is difficult to effectively arrange the scan line SL and the data line DL on the first extension surface ES1. Therefore, the arrangement area of the scan line SL and the data line DL located on the first extension surface ES1 with respect to the total area of the first extension surface ES1 can be larger than the arrangement area of the scan line SL and the data line DL located on the first flat surface PS1 with respect to the total area of the first flat surface PS1. Accordingly, the area of the pixel P with respect to the total area of the first extension surface ES1 can be smaller than the area of the pixel P with respect to the total area of the first flat surface PS1. Therefore, the number of pixels per inch of the first extension surface ES1 can be smaller than the number of pixels per inch of the first flat surface PS1. Therefore, the resolution of the first extension surface ES1 can be lower than the resolution of the first flat surface PS1.

[0162] Similarly, the number of pixels per inch of the second extended surface ES2 can also be less than the number of pixels per inch of the first flat surface PS1. Therefore, the resolution of the second extended surface ES2 can be lower than the resolution of the first flat surface PS1.

[0163] In contrast, although the first side surface SS1 extends longer in the second direction (Y-axis direction), the scan lines SL and data lines DL of the first side surface SS1 can be arranged similarly to the scan lines SL and data lines DL of the first flat surface PS1. Therefore, the number of pixels per inch of the first side surface SS1 can be substantially equal to the number of pixels per inch of the first flat surface PS1. Therefore, the resolution of the first side surface SS1 can be substantially the same as the resolution of the first flat surface PS1.

[0164] Similarly, the number of pixels per inch of the second side surface SS2 can also be substantially equal to the number of pixels per inch of the first flat surface PS1. Therefore, the resolution of the second side surface SS2 can be substantially the same as the resolution of the first flat surface PS1.

[0165] Figure 15 is a cross-sectional view showing Figure 12 an example of II-II'. Figure 15 shows a cross-section of the pixel P of the display panel 300.

[0166] Referring to Figure 15 , the display panel 300 may include a support substrate 301, a flexible substrate 302, a thin film transistor layer 303, a light emitting element layer 304, and a thin film encapsulation layer 305.

[0167] The flexible substrate 302 is disposed on the support substrate 301. Each of the support substrate 301 and the flexible substrate 302 may include a flexible polymer material. For example, each of the support substrate 301 and the flexible substrate 302 may be polyether sulfone (PES), polyacrylate (PA), polyarylate (PAR), polyetherimide (PEI), polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polyphenylene sulfide (PPS), polyallylate, polyimide (PI), polycarbonate (PC), cellulose triacetate (CAT), cellulose acetate propionate (CAP), or a combination thereof. The support substrate 301 may be omitted to increase the flexibility of the display panel 300.

[0168] The thin film transistor layer 303 is formed on the flexible substrate 302. The thin film transistor layer 303 includes thin film transistors 335, a gate insulating layer 336, an interlayer insulating film 337, a protective layer 338, and a planarization layer 339.

[0169] A buffer layer may be formed on the flexible substrate 302. The buffer layer may be formed on the flexible substrate 302 to protect the thin film transistors 335 and the light emitting elements from moisture introduced through the support substrate 301 and the flexible substrate 302 that are vulnerable to moisture penetration. The buffer layer may be composed of a plurality of inorganic layers stacked alternately. For example, the buffer layer may be a multi-layer in which one or more inorganic layers selected from a silicon oxide (SiO x ) layer, a silicon nitride (SiN x ) layer, and a SiON layer are stacked alternately. The buffer layer may be omitted.

[0170] The thin film transistors 335 are formed on the buffer layer. Each of the thin film transistors 335 includes an active layer 331, a gate electrode 332, a source electrode 333, and a drain electrode 334. In Figure 5 , each of the thin film transistors 335 is formed as a top-gate type in which the gate electrode 332 is positioned above the active layer 331. However, it should be noted that the embodiments of the present disclosure are not limited to this case. That is, each of the thin film transistors 335 may also be formed as a bottom-gate type in which the gate electrode 332 is positioned below the active layer 331, or a double-gate type in which the gate electrode 332 is positioned above and below the active layer 331.

[0171] The active layer 331 is formed on the buffer layer. The active layer 331 may be made of a silicon-based semiconductor material or an oxide-based semiconductor material. A light-blocking layer may be formed between the buffer layer and the active layer 331 to block external light from entering the active layer 331.

[0172] The gate insulating layer 336 may be formed on the active layer 331. The gate insulating layer 336 may be an inorganic layer, for example, a silicon oxide (SiO x ) layer, a silicon nitride (SiN x ) layer, or a multi-layer composed of these layers.

[0173] The gate electrode 332 and the gate line may be formed on the gate insulating layer 336. Each of the gate electrode 332 and the gate line may be a single layer or a multi-layer made of any one or more of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), copper (Cu), and their alloys.

[0174] The interlayer insulating film 337 may be formed on the gate electrode 332 and the gate line. The interlayer insulating film 337 may be an inorganic layer, for example, a silicon oxide (SiO x ) layer, a silicon nitride (SiN x ) layer, or a multi-layer composed of these layers.

[0175] The source electrode 333, the drain electrode 334, and the data line may be formed on the interlayer insulating film 337. Each of the source electrode 333 and the drain electrode 334 may be connected to the active layer 331 through a contact hole penetrating the gate insulating layer 336 and the interlayer insulating film 337. Each of the source electrode 333, the drain electrode 334, and the data line may be a single layer or a multilayer made of any one or more of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), copper (Cu), and their alloys.

[0176] The protective layer 338 for insulating the thin film transistor 335 may be formed on the source electrode 333, the drain electrode 334, and the data line. The protective layer 338 may be an inorganic layer, for example, a silicon oxide (SiO x ) layer, a silicon nitride (SiN x ) layer, or a multilayer composed of these layers.

[0177] The planarization layer 339 may be formed on the protective layer 338 to planarize the steps caused by the thin film transistor 335. The planarization layer 339 may be made of an organic layer such as an acrylic resin, an epoxy resin, a phenolic resin, a polyamide resin, or a polyimide resin.

[0178] The light-emitting element layer 304 is formed on the thin film transistor layer 303. The light-emitting element layer 304 includes a light-emitting element and a pixel defining layer 344.

[0179] The light-emitting element and the pixel defining layer 344 are formed on the planarization layer 339. The light-emitting element may be an organic light-emitting device. In this case, each of the light-emitting elements may include an anode 341, a light-emitting layer 342, and a cathode 343.

[0180] The anode 341 may be formed on the planarization layer 339. The anode 341 may be connected to the drain electrode 334 of the thin film transistor 335 through a contact hole penetrating the protective layer 338 and the planarization layer 339.

[0181] The pixel defining layer 344 may be formed on the planarization layer 339 to cover the edge of the anode 341 to separate the pixels. That is, the pixel defining layer 344 serves as a pixel defining layer for defining pixels. Each of the pixels is a region in which the anode 341, the light-emitting layer 342, and the cathode 343 are sequentially stacked such that holes from the anode 341 and electrons from the cathode 343 are combined in the light-emitting layer 342 to emit light.

[0182] The light-emitting layer 342 is formed on the anode 341 and the pixel defining layer 344. The light-emitting layer 342 can be an organic light-emitting layer. Each of the light-emitting layers 342 can emit one of red light, green light, and blue light. The red light can have a peak wavelength range of about 620 to 750 nm, and the green light can have a peak wavelength range of about 495 to 570 nm. Additionally, the blue light can have a peak wavelength range of about 450 to 495 nm. Alternatively, the light-emitting layer 342 can be a white light-emitting layer that emits white light. In this case, the light-emitting layer 342 can be a stack of a red light-emitting layer, a green light-emitting layer, and a blue light-emitting layer, and can be a common layer formed commonly for all pixels. In this case, the display panel 300 can further include color filters for displaying red, green, and blue.

[0183] Each of the light-emitting layers 342 can include a hole transport layer, a light-emitting layer, and an electron transport layer. Additionally, each of the light-emitting layers 342 can be formed in a tandem structure stacked in two or more layers, and in this case, a charge generation layer can be formed between the stacks.

[0184] The cathode 343 is formed on the light-emitting layer 342. The cathode 343 can be formed to cover the light-emitting layer 342. The cathode 343 can be a common layer formed commonly for all pixels.

[0185] When the light-emitting element layer 304 is formed as a top-emission type that emits light in the upward direction, the anode 341 can be made of a metal material with a high reflectivity such as a stacked structure of aluminum and titanium (Ti / Al / Ti), a stacked structure of aluminum and indium tin oxide (ITO / Al / ITO), an APC alloy, or a stacked structure of an APC alloy and indium tin oxide (ITO / APC / ITO). The APC alloy is an alloy of silver (Ag), palladium (Pd), and copper (Cu). Additionally, the cathode 263 can be made of a transparent conductive material (TCO) capable of transmitting light such as indium tin oxide (ITO) or indium zinc oxide (IZO), or can be made of a semi-transmissive conductive material such as magnesium (Mg), silver (Ag), or an alloy of magnesium and silver. When the cathode 343 is made of a semi-transmissive conductive material, the light output efficiency can be improved through a microcavity.

[0186] When the light-emitting element layer 304 is formed as a bottom-emission type that emits light in the downward direction, the anode 341 can be made of a transparent conductive material (TCO) such as indium tin oxide (ITO) or indium zinc oxide (IZO), or can be made of a semi-transmissive conductive material such as magnesium (Mg), silver (Ag), or an alloy of Mg and Ag. The cathode 343 can be made of a metal material with a high reflectivity, such as a stacked structure of aluminum and titanium (Ti / Al / Ti), a stacked structure of aluminum and indium tin oxide (ITO / Al / ITO), an APC alloy, or a stacked structure of an APC alloy and indium tin oxide (ITO / APC / ITO). When the anode 341 is made of a semi-transmissive conductive material, the light output efficiency can be improved through a microcavity.

[0187] The thin-film encapsulation layer 305 is formed on the light-emitting element layer 304. The thin-film encapsulation layer 305 is used to prevent oxygen or moisture from penetrating into the light-emitting layer 342 and the cathode 343. For this purpose, the thin-film encapsulation layer 305 can include at least one inorganic layer. The inorganic layer can be made of silicon nitride, aluminum nitride, zirconium nitride, titanium nitride, hafnium nitride, tantalum nitride, silicon oxide, aluminum oxide, or titanium oxide. Additionally, the thin-film encapsulation layer 305 can further include at least one organic layer. The organic layer can be formed to a sufficient thickness so as to prevent particles from penetrating the thin-film encapsulation layer 305 and entering the light-emitting layer 342 and the cathode 343. The organic layer can include any one of epoxy resin, acrylate, and polyurethane acrylate.

[0188] Figure 16 is an exploded view of a display panel according to another embodiment. Figure 17 is shown in detail Figure 16 a plan view of an example of the second extended surface of

[0189] Figure 16 and Figure 17 The embodiment shown in Figures 12 to 15 differs from the embodiment shown in Figure 16 and Figure 17 in that at least one hole H1 and H2 are formed in the second extended surface ES2. Therefore, in Figures 12 to 15 and

[0190] the description provided in the embodiment shown in Figure 16 and Figure 17 will not be repeated. Referring to Figure 16 and Figure 17 at least one hole H1 and H2 penetrating the display panel 300 can be formed in the second extended surface ES2. Although in

[0191] When viewed in a plan view, the first hole H1 may be rectangular, and when viewed in a plan view, the second hole H2 may be circular. However, embodiments of the present disclosure are not limited thereto. Each of the first hole H1 and the second hole H2 may also have a polygonal shape including a rectangle, a circular shape, or an oval shape.

[0192] The pixel P does not overlap with the first hole H1 and the second hole H2 located in the second extended surface ES2. As Figure 17 shown, the pixel P may be omitted from the region in which the first hole H1 and the second hole H2 are formed.

[0193] In addition, the third scan line SL3 and the third data line DL3 do not overlap with the first hole H1 and the second hole H2 located in the second extended surface ES2. As Figure 17 shown, the third scan line SL3 may travel near one side of each of the first hole H1 and the second hole H2 to be adjacent to the first side S51 of the second extended surface ES2. In this case, the third data line DL3 may be arranged to be adjacent to the second side S52 of the second extended surface ES2.

[0194] Although in Figure 16 and Figure 17 at least one of the holes H1 and H2 is only formed in the second extended surface ES2, embodiments of the present disclosure are not limited thereto. At least one of the holes H1 and H2 may also be only formed in the first extended surface ES1 or formed in both the first extended surface ES1 and the second extended surface ES2. That is, at least one of the holes H1 and H2 may be formed in any one or more of the first flat surface PS1, the first side surface SS1, the second side surface SS2, the first extended surface ES1, and the second extended surface ES2.

[0195] According to the embodiments shown in 16 and Figure 17 at least one of the holes H1 and H2 may be formed in any one or more of the first flat surface PS1, the first side surface SS1, the second side surface SS2, the first extended surface ES1, and the second extended surface ES2 of the display panel 300, and the charging terminal or the headphone terminal of the display device 10 may be exposed through at least one of the holes H1 and H2, or the speaker hole of the display device 10 may be used as at least one of the holes H1 and H2.

[0196] Figure 18 is an exploded view of a display panel according to another embodiment. Figures 19 to 25 is Figure 18 a perspective view, a plan view, a bottom view, a front view, a rear view, a left side view, and a right side view of the display panel.

[0197] Figure 18 and Figures 19 to 25The embodiments shown in Figure 4 and Figures 5 to 11 are different from the embodiments shown therein in that: the length L2 of the third side S43 of the first extended surface ES1 is less than the length L1 of each of the first side S21 and the second side S22 of the first side surface SS1, and the length L4 of the third side S53 of the second extended surface ES2 is less than the length L3 of each of the first side S31 and the second side S32 of the second side surface SS2. Additionally, Figure 18 and Figures 19 to 25 the embodiments shown in Figure 4 and Figures 5 to 11 are different from the embodiments shown therein in that: the corners C11 to C14 of the first flat surface PS1 are rounded with a predetermined curvature. Thus, in Figure 18 and Figures 19 to 25 , the descriptions already provided in the embodiments shown in Figure 4 and Figures 5 to 11 will not be repeated.

[0198] Referring to Figure 18 and Figures 19 to 25 , the first flat surface PS1 may include a first corner C11 between the first side S11 and the third side S13 of the first flat surface PS1, a second corner C12 between the second side S12 and the fourth side S14 of the first flat surface PS1, a third corner C13 between the first side S11 and the fourth side S14 of the first flat surface PS1, and a fourth corner C14 between the second side S12 and the third side S13 of the first flat surface PS1. The first corner C11, the second corner C12, the third corner C13, and the fourth corner C14 may be rounded with a predetermined curvature.

[0199] When the first flat surface PS1 includes the corners C11 to C14, the length of the first flat surface PS1 in the second direction (Y-axis direction) may be greater than the length of the first side surface SS1 in the second direction (Y-axis direction) and the length of the second side surface SS2 in the second direction (Y-axis direction). In this case, as shown in Figure 18 and Figure 24 , in the left side view of the display panel 300, the second side S22 of the first side surface SS1 may face the third side S53 of the second extended surface ES2. In Figure 24In [description], there is a gap between the second side S22 of the first side surface SS1 and the third side S53 of the second extended surface ES2. However, the second side S22 of the first side surface SS1 may also contact the third side S53 of the second extended surface ES2. The region where the second side S22 of the first side surface SS1 and the third side S53 of the second extended surface ES2 face each other may overlap with the light-blocking portion LS of the cover window 100. Therefore, the region where the second side S22 of the first side surface SS1 and the third side S53 of the second extended surface ES2 face each other may be covered by the light-blocking portion LS of the cover window 100, so that this region is not visible from the outside.

[0200] As Figure 18 and Figure 25 shown in [reference], in the right-side view of the display panel 300, the second side S32 of the second side surface SS2 may face the third side S43 of the first extended surface ES1. In Figure 25 [description], there is a gap between the second side S32 of the second side surface SS2 and the third side S43 of the first extended surface ES1. However, the second side S32 of the second side surface SS2 may also contact the third side S43 of the first extended surface ES1. The region where the second side S32 of the second side surface SS2 and the third side S43 of the first extended surface ES1 face each other may overlap with the light-blocking portion LS of the cover window 100. Therefore, the region where the second side S32 of the second side surface SS2 and the third side S43 of the first extended surface ES1 face each other may be covered by the light-blocking portion LS of the cover window 100, such that this region is not visible from the outside.

[0201] As Figure 18 shown in [reference], the scan driver 330 may be formed along the second side S22 of the first side surface SS1 and the third corner C13 and the fourth side S14 of the first flat surface PS1. Although in Figure 18 [reference], the scan driver 330 is curved with a curvature corresponding to the third corner C13 of the first flat surface PS1, the embodiments of the present disclosure are not limited thereto. The scan driver 330 may also be formed in a straight line in a region corresponding to the third corner C13 of the first flat surface PS1.

[0202] Since the first extended surface ES1 is curved from the first side S21 of the first side surface SS1 in the first direction (X-axis direction), a large stress is applied to the first side S21 of the first side surface SS1 due to the bending force of the first extended surface ES1. To reduce the stress applied to the first side S21 of the first side surface SS1 due to the bending force of the first extended surface ES1, the length L2 of the third side S43 of the first extended surface ES1 may be less than the length L1 of each of the first side S21 and the second side S22 of the first side surface SS1. In this case, as Figure 18 andFigure 22 As shown in the front view of the display panel 300, a first gap G1 may be formed between a first side S41 of the first extended surface ES1 and a third side S13 of the first flat surface PS1. The first gap G1 may overlap with the light-blocking portion LS of the cover window 100. Accordingly, the first gap G1 may be covered by the light-blocking portion LS of the cover window 100 such that the first gap G1 is not visible from the outside.

[0203] Since the second extended surface ES2 is bent in the first direction (X-axis direction) from a first side S31 of the second side surface SS2, a large stress is applied to the first side S31 of the second side surface SS2 due to the bending force of the second extended surface ES2. In order to reduce the stress applied to the first side S31 of the second side surface SS2 due to the bending force of the second extended surface ES2, the length L4 of a third side S53 of the second extended surface ES2 may be less than the length L3 of each of the first side S31 and a second side S32 of the second side surface SS2. In this case, as Figure 18 and Figure 23 shown in the rear view of the display panel 300, a second gap G2 may be formed between a first side S51 of the second extended surface ES2 and a fourth side S14 of the first flat surface PS1. The second gap G2 may overlap with the light-blocking portion LS of the cover window 100. Accordingly, the second gap G2 may be covered by the light-blocking portion LS of the cover window 100 such that the second gap G2 is not visible from the outside. The length of the first gap G1 and the length of the second gap G2 may be substantially the same.

[0204] In Figure 18 and Figures 19 to 25 the first side surface SS1 protrudes further in the second direction (Y-axis direction) than a first contact point CP11 between a first corner C11 and a first side S11 of the first flat surface PS1, and a first side S21 of the first side surface SS1 is formed side by side with a third side S13 of the first flat surface PS1 in the first direction (X-axis direction). However, embodiments of the present disclosure are not limited thereto. The first side S21 of the first side surface SS1 may also be disposed between the first contact point CP11 and the third side S13 of the first flat surface PS1.

[0205] It should be noted that, for ease of description, the light-blocking portion LS of the cover window 100 is only shown in Figures 22 to 25 and is not shown in Figure 18 and Figure 19 .

[0206] According to Figure 18 and Figures 19 to 25In the embodiment shown in , the length L2 of the third side S43 of the first extension surface ES1 can be smaller than the length L1 of each of the first side S21 and the second side S22 of the first side surface SS1, and the length L4 of the third side S53 of the second extension surface ES2 can be smaller than the length L3 of each of the first side S31 and the second side S32 of the second side surface SS2. Therefore, the stress applied to the first side S21 of the first side surface SS1 due to the bending force of the first extension surface ES1 and the stress applied to the first side S31 of the second side surface SS2 due to the bending force of the second extension surface ES2 can be reduced. In addition, the first extension surface ES1 and the second extension surface ES2 can be more easily bent in the first direction (X-axis direction).

[0207] Figure 26 is an expanded view of a display panel according to another embodiment. Figures 27 to 33 yes Figure 26 The display panel includes perspective view, plan view, bottom view, front view, rear view, left view and right view.

[0208] Figure 26 and Figures 27 to 33 The embodiments shown in Figure 18 and Figures 19 to 25 The difference of the embodiment shown in is that the area between the first side S11 and the third side S13 of the first flat surface PS1 and the area between the first side S11 of the first flat surface PS1 and the first side S21 of the first side surface SS1 are formed to have a compound curvature, and the area between the second side S12 and the fourth side S14 of the first flat surface PS1 and the area between the second side S12 of the first flat surface PS1 and the first side S31 of the second side surface SS2 are formed to have a compound curvature. Figure 26 and Figures 27 to 33 will not repeat the Figure 18 and Figures 19 to 25 The description is provided in the embodiments shown in FIG.

[0209] Reference Figure 26 and Figures 27 to 33 Since the first extension surface ES1 is bent in the first direction (X-axis direction) from the first side S21 of the first side surface SS1, the first contact point CP11 disposed between the first side S11 and the third side S13 of the first flat surface PS1 may receive the greatest stress due to the bending force of the first extension surface ES1. In order to reduce the stress applied to the first contact point CP11, the area between the third side S13 of the first flat surface PS1 and the first contact point CP11 and the area between the first side S21 of the first side surface SS1 and the first contact point CP11 may be rounded.

[0210] Specifically, a first curvature portion CV1 curved with a first curvature from a third side S13 of the first flat surface PS1 and a second curvature portion CV2 curved with a second curvature between the first curvature portion CV1 and the first contact point CP11 can be formed between the third side S13 of the first flat surface PS1 and the first contact point CP11. Herein, the tangent line of the first curvature portion CV1 can have a greater positive slope from the third side S13 of the first flat surface PS1 toward the second curvature portion CV2. The tangent line of the second curvature portion CV2 can have a smaller positive slope from the first curvature portion CV1 toward the first contact point CP11.

[0211] A third curvature portion CV3 curved with a third curvature and a fourth curvature portion CV4 curved with a fourth curvature between the third curvature portion CV3 and a first side S21 of the first side surface SS1 can be included between the first contact point CP11 and the first side S21 of the first side surface SS1. Herein, the tangent line of the third curvature portion CV3 can have a greater negative slope from the first contact point CP11 toward the fourth curvature portion CV4. The tangent line of the fourth curvature portion CV4 can have a smaller negative slope from the third curvature portion CV3 toward the first side S21 of the first side surface SS1.

[0212] In addition, since the second extension surface ES2 is curved in the first direction (X-axis direction) from a first side S31 of the second side surface SS2, a second contact point CP12 provided between a second side S12 and a fourth side S14 of the first flat surface PS1 can bear the maximum stress due to the bending force of the second extension surface ES2. To reduce the stress applied to the second contact point CP12, the regions between the fourth side S14 of the first flat surface PS1 and the second contact point CP12 and between the first side S31 of the second side surface SS2 and the second contact point CP12 can be rounded. For example, a complex curvature portion having a complex curvature can be formed between the fourth side S14 of the first flat surface PS1 and the second contact point CP12 and between the first side S31 of the second side surface SS2 and the second contact point CP12.

[0213] Specifically, a fifth curvature portion CV5 that is curved with a fifth curvature from a fourth side S14 of the first flat surface PS1 and a sixth curvature portion CV6 that is curved with a sixth curvature between the fifth curvature portion CV5 and the second contact point CP12 can be included between the fourth side S14 of the first flat surface PS1 and the second contact point CP12. The fifth curvature can be substantially the same as the first curvature, and the sixth curvature can be substantially the same as the second curvature, but embodiments of the present disclosure are not limited thereto. Here, a tangent to the fifth curvature portion CV5 can have a greater positive slope from the fourth side S14 of the first flat surface PS1 toward the sixth curvature portion CV6. A tangent to the sixth curvature portion CV6 can have a smaller positive slope from the fifth curvature portion CV5 toward the second contact point CP12.

[0214] A seventh curvature portion CV7 that is curved with a seventh curvature between the second contact point CP12 and a first side S31 of the second side surface SS2 and an eighth curvature portion CV8 that is curved with an eighth curvature between the seventh curvature portion CV7 and the first side S31 of the second side surface SS2 can be included between the second contact point CP12 and the first side S31 of the second side surface SS2. Here, a tangent to the seventh curvature portion CV7 can have a greater negative slope from the second contact point C12 toward the eighth curvature portion CV8. A tangent to the eighth curvature portion CV8 can have a smaller negative slope from the seventh curvature portion CV7 toward the first side S31 of the second side surface SS2.

[0215] According to Figure 26 and Figures 27 to 33 In the embodiment shown in, complex curvature portions can be formed between the third side S13 of the first flat surface PS1 and the first contact point CP11 and between the first side S21 of the first side surface SS1 and the first contact point CP11, and complex curvature portions can be formed between the fourth side S14 of the first flat surface PS1 and the second contact point CP12 and between the first side S31 of the second side surface SS2 and the second contact point CP12. The stress applied to the first contact point CP11 due to the bending force of the first extended surface ES1 and the stress applied to the second contact point CP12 due to the bending force of the second extended surface ES2 can be reduced. Additionally, the first extended surface ES1 and the second extended surface ES2 can be more easily bent in the first direction (X-axis direction).

[0216] Figure 34 is an exploded view of a display panel according to another embodiment. Figures 35 to 41 is Figure 34 a perspective view, a plan view, a bottom view, a front view, a rear view, a left side view, and a right side view of the display panel of

[0217] Figure 34 and Figures 35 to 41The embodiment shown in Figure 4 and Figures 5 to 11 differs from the embodiment shown in that the display panel 300 further includes a first edge surface EE1 provided between the first flat surface PS1 and the first side surface SS1 and a second edge surface EE2 provided between the first flat surface PS1 and the second side surface SS2, and the corners C11 to C14 of the first flat surface PS1 are rounded with a predetermined curvature. Therefore, in Figure 34 and Figures 35 to 41 , the descriptions provided in the embodiments already shown in Figure 4 and Figures 5 to 11 will not be repeated.

[0218] Referring to Figure 34 and Figures 35 to 41 , the first edge surface EE1 can be provided between the first flat surface PS1 and the first side surface SS1. The first edge surface EE1 can be curved from the first side S11 of the first flat surface PS1. In this case, the angle formed by the first edge surface EE1 and the first flat surface PS1 can be 90 degrees or less. The first side surface SS1 can be curved from the first side S61 of the first edge surface EE1 in the third direction (Z-axis direction). In this case, the angle formed by the first edge surface EE1 and the first side surface SS1 can be 90 degrees or less.

[0219] The first edge surface EE1 can include a first side S61, a first corner C11, and a third corner C13, and can share the first side S11 of the first flat surface PS1 as one side with the first flat surface PS1. The first side S61 of the first edge surface EE1 and the first side S11 of the first flat surface PS1 can be parallel to each other. The first corner C11 can be provided between the third side S13 of the first flat surface PS1 and the first side S61 of the first edge surface EE1, and can be rounded with a predetermined curvature. The third corner C13 can be provided between the fourth side S14 of the first flat surface PS1 and the first side S61 of the first edge surface EE1, and can be rounded with a predetermined curvature. In this case, the length of the first side S11 of the first flat surface PS1 can be greater than the length of the first side S61 of the first edge surface EE1.

[0220] When the first edge surface EE1 exists between the first flat surface PS1 and the first side surface SS1, the angle at which the first extension surface ES1 is curved from the first side S21 of the first side surface SS1 can be reduced. Therefore, the stress applied to the first side S21 of the first side surface SS1 due to the bending force of the first extension surface ES1 can be reduced. Therefore, even if it is not the same as Figure 18In the embodiment shown in [reference], the length L2 of the third side S43 of the first extension surface ES1 is made smaller than the length L1 of each of the first side S21 and the second side S22 of the first side surface SS1 to reduce the stress applied to the first side S21 of the first side surface SS1. The first extension surface ES1 can also be easily bent in the first direction (X-axis direction).

[0221] The second edge surface EE2 can be provided between the first flat surface PS1 and the second side surface SS2. The second edge surface EE2 can be bent from the second side S12 of the first flat surface PS1. In this case, the angle formed by the second edge surface EE2 and the first flat surface PS1 can be 90 degrees or less. The second side surface SS2 can be bent from the first side S71 of the second edge surface EE2 in the third direction (Z-axis direction). In this case, the angle formed by the second edge surface EE2 and the second side surface SS2 can be 90 degrees or less.

[0222] The second edge surface EE2 can include a first side S71, a second corner C12, and a fourth corner C14, and can share the second side S12 of the first flat surface PS1 as one side with the first flat surface PS1. The first side S71 of the second edge surface EE2 and the second side S12 of the first flat surface PS1 can be parallel to each other. The second corner C12 can be provided between the third side S13 of the first flat surface PS1 and the first side S71 of the second edge surface EE2, and can be rounded with a predetermined curvature. The fourth corner C14 can be provided between the fourth side S14 of the first flat surface PS1 and the first side S71 of the second edge surface EE2, and can be rounded with a predetermined curvature. In this case, the length of the second side S12 of the first flat surface PS1 can be greater than the length of the first side S71 of the second edge surface EE2.

[0223] When the second edge surface EE2 exists between the first flat surface PS1 and the second side surface SS2, the angle at which the second extension surface ES2 is bent from the first side S31 of the second side surface SS2 can be reduced. Therefore, the stress applied to the first side S31 of the second side surface SS2 due to the bending force of the second extension surface ES2 can be reduced. Thus, even if the length L4 of the third side S53 of the second extension surface ES2 is not made smaller than the length L3 of each of the first side S31 and the second side S32 of the second side surface SS2 as in the embodiment shown in [reference] to reduce the stress applied to the first side S31 of the second side surface SS2, the second extension surface ES2 can also be easily bent in the first direction (X-axis direction). Figure 18 In the embodiment shown in [reference], the length L2 of the third side S43 of the first extension surface ES1 is made smaller than the length L1 of each of the first side S21 and the second side S22 of the first side surface SS1 to reduce the stress applied to the first side S21 of the first side surface SS1. The first extension surface ES1 can also be easily bent in the first direction (X-axis direction).

[0224] When the first flat surface PS1 includes the corners C11 to C14, the length of the first flat surface PS1 in the second direction (Y-axis direction) can be greater than the length of the first side surface SS1 in the second direction (Y-axis direction) and the length of the second side surface SS2 in the second direction (Y-axis direction). In this case, as Figure 34 and Figure 40 shown in, in the left side view of the display panel 300, the second side S22 of the first side surface SS1 can face the third side S53 of the second extended surface ES2. In Figure 40 , there is a gap between the second side S22 of the first side surface SS1 and the third side S53 of the second extended surface ES2. However, the second side S22 of the first side surface SS1 can also contact the third side S53 of the second extended surface ES2. The area where the second side S22 of the first side surface SS1 and the third side S53 of the second extended surface ES2 face each other can overlap with the light-blocking portion LS of the cover window 100. Therefore, the area where the second side S22 of the first side surface SS1 and the third side S53 of the second extended surface ES2 face each other can be covered by the light-blocking portion LS of the cover window 100, so that this area is not visible from the outside.

[0225] As Figure 34 and Figure 41 shown in, in the right side view of the display panel 300, the second side S32 of the second side surface SS2 can face the third side S43 of the first extended surface ES1. In Figure 41 , there is a gap between the second side S32 of the second side surface SS2 and the third side S43 of the first extended surface ES1. However, the second side S32 of the second side surface SS2 can also contact the third side S43 of the first extended surface ES1. The area where the second side S32 of the second side surface SS2 and the third side S43 of the first extended surface ES1 face each other can overlap with the light-blocking portion LS of the cover window 100. Therefore, the area where the second side S32 of the second side surface SS2 and the third side S43 of the first extended surface ES1 face each other can be covered by the light-blocking portion LS of the cover window 100, so that this area is not visible from the outside.

[0226] As Figure 34 shown in, the scan driver 330 can be formed along the second side S22 of the first side surface SS1, the third corner C13 of the first edge surface EE1, and the fourth side S14 of the first flat surface PS1. Although the scan driver 330 bends with a curvature corresponding to the third corner C13 of the first flat surface PS1 in Figure 34 , the embodiments of the present disclosure are not limited thereto. The scan driver 330 can also be formed in a straight line in the area corresponding to the third corner C13 of the first flat surface PS1.

[0227] It should be noted that, for ease of description, the light-blocking portion LS covering the window 100 is only shown in Figure 40 and Figure 41 and is not shown in Figure 34 and Figure 35 .

[0228] According to Figure 34 and Figures 35 to 41 in the embodiment shown, the angle formed by the bending of the first extended surface ES1 from the first edge S21 of the first side surface SS1 can be reduced by the first edge surface EE1 between the first flat surface PS1 and the first side surface SS1. Additionally, the angle formed by the bending of the second extended surface ES2 from the first edge S31 of the second side surface SS2 can be reduced by the second edge surface EE2 between the first flat surface PS1 and the second side surface SS2. Therefore, the stress applied to the first edge S21 of the first side surface SS1 due to the bending force of the first extended surface ES1 and the stress applied to the first edge S31 of the second side surface SS2 due to the bending force of the second extended surface ES2 can be reduced.

[0229] Figure 42 is an exploded view of a display panel according to another embodiment. Figures 43 to 49 is Figure 42 the perspective view, plan view, bottom view, front view, rear view, left side view, and right side view of the display panel of

[0230] Figure 42 and Figures 43 to 49 The embodiment shown in Figure 4 and Figures 5 to 11 differs from the embodiment shown in Figure 42 and Figures 43 to 49 in that: the display panel 300 further includes a third extended surface ES3 extending from the second edge S22 of the first side surface SS1 and a fourth extended surface ES4 extending from the second edge S32 of the second side surface SS2. Therefore, in Figure 4 and Figures 5 to 11 the description provided in the embodiment already shown in

[0231] Referring to Figure 42 and Figures 43 to 49 , the third extended surface ES3 can extend from the second edge S22 of the first side surface SS1. The third extended surface ES3 can include a first edge S91, a second edge S92, and a third edge S93, and can share the second edge S22 of the first side surface SS1 as one of its sides. The first edge S91 and the second edge S92 of the third extended surface ES3 can be parallel to each other and can be longer than the third edge S93 of the third extended surface ES3.

[0232] The third extended surface ES3 can be bent in a first direction (X-axis direction) from the second side S22 of the first side surface SS1. As Figure 43 and Figure 46 shown, the third extended surface ES3 can form the lower side surface of the display panel 300 together with the second extended surface ES2. In this case, the second extended surface ES2 and the third extended surface ES3 can overlap with the lower side surface DSS4 of the cover window 100.

[0233] The first side S91 of the third extended surface ES3 can face the fourth side S14 of the first flat surface PS1, and the third side S93 of the third extended surface ES3 can face the third side S53 of the second extended surface ES2. There may be a slight gap between the first side S91 of the third extended surface ES3 and the fourth side S14 of the first flat surface PS1 and between the third side S93 of the third extended surface ES3 and the third side S53 of the second extended surface ES2. Alternatively, the first side S91 of the third extended surface ES3 and the fourth side S14 of the first flat surface PS1 can be in contact with each other, and the third side S93 of the third extended surface ES3 and the third side S53 of the second extended surface ES2 can be in contact with each other. As Figure 47 shown, the region where the third side S93 of the third extended surface ES3 and the third side S53 of the second extended surface ES2 face each other can overlap with the light-blocking portion LS of the cover window 100. Therefore, the gap between the third side S93 of the third extended surface ES3 and the third side S53 of the second extended surface ES2 can be covered by the light-blocking portion LS of the cover window 100, making the gap invisible from the outside.

[0234] The length of the third side S93 of the third extended surface ES3 can be substantially the same as the length of the third side S53 of the second extended surface ES2. Additionally, the sum of the length of the first side S91 of the third extended surface ES3 and the length of the first side S51 of the second extended surface ES2 can be substantially the same as the length of the fourth side S14 of the first flat surface PS1. When the sum of the length of the first side S91 of the third extended surface ES3 and the length of the first side S51 of the second extended surface ES2 is less than the length of the fourth side S14 of the first flat surface PS1, there can be a gap between the third side S93 of the third extended surface ES3 and the third side S53 of the second extended surface ES2.

[0235] In Figure 43 and Figure 46 shown, the length of the first side S91 of the third extended surface ES3 is substantially the same as the length of the first side S51 of the second extended surface ES2. However, the embodiments of the present disclosure are not limited thereto. The length of the first side S91 of the third extended surface ES3 can also be different from the length of the first side S51 of the second extended surface ES2.

[0236] The fourth extended surface ES4 can extend from the second edge S32 of the second side surface SS2. The fourth extended surface ES4 can include a first edge S101, a second edge S102, and a third edge S103, and can share the second edge S32 of the second side surface SS2 as one of its sides. The first edge S101 and the second edge S102 of the fourth extended surface ES4 can be parallel to each other and can be longer than the third edge S103 of the fourth extended surface ES4.

[0237] The fourth extended surface ES4 can be curved from the second edge S32 of the second side surface SS2 in the first direction (X-axis direction). As Figure 43 and Figure 45 shown, the fourth extended surface ES4 can form the upper side surface of the display panel 300 together with the first extended surface ES1. In this case, the first extended surface ES1 and the fourth extended surface ES4 can overlap with the upper side surface DSS3 of the cover window 100.

[0238] The first edge S101 of the fourth extended surface ES4 can face the third edge S13 of the first flat surface PS1, and the third edge S103 of the fourth extended surface ES4 can face the third edge S43 of the first extended surface ES1. There can be a slight gap between the first edge S101 of the fourth extended surface ES4 and the third edge S13 of the first flat surface PS1 and between the third edge S103 of the fourth extended surface ES4 and the third edge S43 of the first extended surface ES1. Alternatively, the first edge S101 of the fourth extended surface ES4 and the third edge S13 of the first flat surface PS1 can be in contact with each other, and the third edge S103 of the fourth extended surface ES4 and the third edge S43 of the first extended surface ES1 can be in contact with each other. As Figure 46 shown, the region where the third edge S103 of the fourth extended surface ES4 and the third edge S43 of the first extended surface ES1 face each other can overlap with the light-blocking portion LS of the cover window 100. Therefore, the gap between the third edge S103 of the fourth extended surface ES4 and the third edge S43 of the first extended surface ES1 can be covered by the light-blocking portion LS of the cover window 100, making the gap invisible from the outside.

[0239] The length of the third side S103 of the fourth extended surface ES4 can be substantially the same as the length of the third side S43 of the first extended surface ES1. Additionally, the sum of the length of the first side S101 of the fourth extended surface ES4 and the length of the first side S41 of the first extended surface ES1 can be substantially the same as the length of the third side S13 of the first flat surface PS1. When the sum of the length of the first side S101 of the fourth extended surface ES4 and the length of the first side S41 of the first extended surface ES1 is less than the length of the third side S13 of the first flat surface PS1, a gap can exist between the third side S103 of the fourth extended surface ES4 and the third side S43 of the first extended surface ES1.

[0240] In Figure 43 and Figure 45 , the length of the first side S101 of the fourth extended surface ES4 is substantially the same as the length of the first side S41 of the first extended surface ES1. However, embodiments of the present disclosure are not limited thereto. The length of the first side S101 of the fourth extended surface ES4 can also be different from the length of the first side S41 of the first extended surface ES1.

[0241] Additionally, the area where the scan lines SL and data lines DL are arranged on each of the third extended surface ES3 and the fourth extended surface ES4 relative to the total area of the third extended surface ES3 or the fourth extended surface ES4 can be greater than the area where the scan lines SL and data lines DL are arranged on the first flat surface PS1 relative to the total area of the first flat surface PS1. Therefore, the number of pixels per inch for each of the third extended surface ES3 and the fourth extended surface ES4 can also be less than the number of pixels per inch of the first flat surface PS1. Accordingly, the resolution of each of the third extended surface ES3 and the fourth extended surface ES4 can be lower than the resolution of the first flat surface PS1.

[0242] In Figure 42 and Figures 43 to 49 In the embodiments shown in Figure 18 and Figures 19 to 25 In the embodiments shown in

[0243] It should be noted that, for ease of description, the light-blocking portion LS of the cover window 100 is only shown in Figure 46 and Figure 47 and inFigure 42 and Figure 43 is not shown.

[0244] In addition, in the embodiments shown in Figure 42 and Figures 43 to 49 as in the embodiments shown in Figure 26 and Figures 27 to 33 the region between the first side S11 and the third side S13 of the first flat surface PS1 and the region between the first side S11 of the first flat surface PS1 and the first side S21 of the first side surface SS1 may be formed to have a complex curvature, and the region between the second side S12 and the fourth side S14 of the first flat surface PS1 and the region between the second side S12 of the first flat surface PS1 and the first side S31 of the second side surface SS2 may be formed to have a complex curvature. Additionally, as in the embodiments shown in Figure 26 and Figures 27 to 33 the region between the first side S11 and the fourth side S14 of the first flat surface PS1 and the region between the first side S11 of the first flat surface PS1 and the second side S22 of the first side surface SS1 may be formed to have a complex curvature, and the region between the second side S12 and the third side S13 of the first flat surface PS1 and the region between the second side S12 of the first flat surface PS1 and the second side S32 of the second side surface SS2 may be formed to have a complex curvature.

[0245] In addition, in the embodiments shown in Figure 42 and Figures 43 to 49 as in the embodiments shown in Figure 34 and Figures 35 to 41 the display panel 300 may further include a first edge surface EE1 provided between the first flat surface PS1 and the first side surface SS1 and a second edge surface EE2 provided between the first flat surface PS1 and the second side surface SS2, and the corners C11 to C14 of the first flat surface PS1 may be rounded with a predetermined curvature.

[0246] As described above, according to the embodiments shown in Figure 42 and Figures 43 to 49 the display panel 300 has pixels provided not only on the first flat surface PS1 but also on the first side surface SS1, the second side surface SS2, the first extension surface ES1, the second extension surface ES2, the third extension surface ES3, and the fourth extension surface ES4. Therefore, images can be displayed on the first side surface SS1, the second side surface SS2, the first extension surface ES1, the second extension surface ES2, the third extension surface ES3, and the fourth extension surface ES4.

[0247] Figure 50It is an exploded view of a display panel according to another embodiment. Figure 51 is Figure 50 a rear view of the display panel of.

[0248] Figure 50 and Figure 51 The embodiments shown in Figure 4 and Figures 5 to 11 differ from the embodiments shown in Figure 50 and Figure 51 in that: The display panel 300 includes a second flat surface PS2. Thus, in Figure 4 and Figures 5 to 11 the descriptions provided in the embodiments shown in

[0249] will not be repeated. Figure 50 and Figure 51 Referring to Figure 50 and Figure 50 and Figure 51 the second flat surface PS2 may include a first side S81, a second side S82, and a third side S83, and may share the third side S33 of the second side surface SS2 as one side. The first side S81 of the second flat surface PS2 may be longer than the second side S82 and the third side S83 of the second flat surface PS2. The first side S81 of the second flat surface PS2 and the third side S33 of the second side surface SS2 may be parallel to each other, and the second side S82 and the third side S83 of the second flat surface PS2 may be parallel to each other. Although the first side S81 of the second flat surface PS2 and the third side S33 of the second side surface SS2 have the same length in

[0250] the first side S81 of the second flat surface PS2 and the third side S33 of the second side surface SS2 may also have different lengths. Additionally, although the second side S82 and the third side S83 of the second flat surface PS2 have the same length, the second side S82 and the third side S83 of the second flat surface PS2 may also have different lengths. As shown in

[0251] The second extended surface ES2 bends in the first direction (X-axis direction) from the first side S31 of the second side surface SS2. Thus, the second side S52 of the second extended surface ES2 can face the third side S83 of the second flat surface PS2. In this case, there may be a small gap between the second side S52 of the second extended surface ES2 and the third side S83 of the second flat surface PS2, or the second side S52 of the second extended surface ES2 and the third side S83 of the second flat surface PS2 may be in contact with each other.

[0252] The scan driver 330 can output scan signals to the scan lines. The scan driver 330 can be disposed on the first flat surface PS1, the second flat surface PS2, the first side surface SS1, and the second side surface SS2. The scan driver 330 can be disposed adjacent to the fourth side S14 of the first flat surface PS1, the third side S83 of the second flat surface PS2, the second side S22 of the first side surface SS1, and the first side S31 of the second side surface SS2.

[0256] Referring to Figure 53 and Figures 54 to 60 , the third side surface SS3 may extend from the third side S13 of the first flat surface PS1.

The third side surface SS3 may overlap with the upper side surface DSS3 of the cover window 100.

[0257] The fourth side surface SS4 may extend from the fourth side S14 of the first flat surface PS1. As shown in Figure 54 and Figure 60 , the fourth side surface SS4 may be the lower side surface of the display panel 300. The fourth side surface SS4 may include a first side S121, a second side S122, and a third side S123, and may share the fourth side S14 of the first flat surface PS1 as one side with the first flat surface PS1.

Although in Figure 53 , the first side S121 and the second side S122 of the fourth side surface SS4 have the same length, the first side S121 and the second side S122 of the fourth side surface SS4 may also have different lengths. The fourth side surface SS4 may overlap with the lower side surface DSS4 of the cover window 100.

[0258] The first flat surface PS1 may further include a first corner C11, a second corner C12, a third corner C13, and a fourth corner C14.

Alternatively, at least two of the first corner C11, the second corner C12, the third corner C13, and the fourth corner C14 may have different curvatures.

[0259] The first side S21 of the first side surface SS1 and the first side S111 of the third side surface SS3 may not contact each other, and a gap may exist between the first side S21 of the first side surface SS1 and the first side S111 of the third side surface SS3. The second side S22 of the first side surface SS1 and the second side S122 of the fourth side surface SS4 may not contact each other, and a gap may exist between the second side S22 of the first side surface SS1 and the second side S122 of the fourth side surface SS4.

[0261] The light blocking portion LS of the cover window 100 may overlap the scan driver 330 so that the scan driver 330 is not visible from the outside. In addition, the light blocking portion LS of the cover window 100 may overlap the wiring provided in the non-display area of ​​the display panel 300 so that the wiring is not visible from the outside. For this purpose, Figure 55 , Figure 57 , Figure 58 , Figure 59 and Figure 60As shown, the light-blocking portion LS of the cover window 100 can be arranged to be adjacent to the second side S22 of the first side surface SS1, the third corner C13 of the first flat surface PS1, the second sides S122, S123, and the first side S121 of the fourth side surface SS4, the second corner C12 of the first flat surface PS1, and the first side S31 of the second side surface SS2.

In this case, the light-blocking portion LS of the cover window 100 can have a maximum width of 3 mm.

[0262] Alternatively, the scan driver 330 can be arranged to be adjacent to the third side S123 of the fourth side surface SS4.

In this case, the light-blocking portion LS of the cover window 100 can have a maximum width of 1 mm.

[0263] It should be noted that for ease of description, the light-blocking portion LS of the cover window 100 is only shown in Figure 55 and Figures 57 to 60 and is not shown in Figure 53 and Figure 54

[0264] According to Figure 53 and Figures 54 to 60 the embodiments shown, the display panel 300 can include a first flat surface PS1, a first side surface SS1, a second side surface SS2, a third side surface SS3, and a fourth side surface SS4. Accordingly, the display panel 300 has pixels disposed not only on the first flat surface PS1 but also on the first side surface SS1, the second side surface SS2, the third side surface SS3, and the fourth side surface SS4. Thus, an image can be displayed on the first side surface SS1, the second side surface SS2, the third side surface SS3, and the fourth side surface SS4. That is, the display panel 300 can display an image on all surfaces except the side surfaces at the first corner C11, the second corner C12, the third corner C13, and the fourth corner C14.

[0265] Figure 61 is an exploded view of a display panel according to another embodiment. Figures 62 to 68 is Figure 61 a perspective view, a plan view, a bottom view, a front view, a rear view, a left side view, and a right side view of the display panel.​

[0266] In Figure 61 and Figures 62 to 68 The embodiments shown in are different from the embodiments shown in Figure 53 and Figures 54 to 60 in that: The display panel 300 includes a first corner surface CS1 and a fourth corner surface CS4 protruding from the third side surface SS3, and includes a second corner surface CS2 and a third corner surface CS3 protruding from the fourth side surface SS4. Therefore, in Figure 61 and Figures 62 to 68 the descriptions provided in the embodiments already shown in Figure 53 and Figures 54 to 60 will not be repeated.

[0267] Referring to Figure 61 and Figures 62 to 68 the first corner surface CS1 can extend from the first edge S111 of the third side surface SS3. The first corner surface CS1 can be the first corner side surface of the display panel 300 corresponding to the first corner C11. The first corner surface CS1 can include a first edge S131, a second edge S132, and a third edge S133, and can share the first edge S111 of the third side surface SS3 as one side.
