In addition, in the following description of examples or embodiments of the present disclosure, detailed descriptions of well-known functions and components incorporated herein will be omitted when it is determined that the description may make the subject matter in some embodiments of the present disclosure less clear. Terms such as "including", "having", "comprising", "consisting of", and "formed by" used herein are generally intended to allow the addition of other components unless these terms are used together with the term "only". As used herein, the singular form is intended to include the plural form unless the context clearly indicates otherwise.

[0036] Terms such as "first", "second", "A", "B", "(A)" or "(B)" may be used herein to describe elements of the present disclosure. Each of these terms is not used to define the nature, order, sequence, quantity, etc. of an element, but is only used to distinguish the corresponding element from other elements.

[0037] When it is mentioned that a first element is "connected or coupled", "contacted or overlapped", etc. with a second element, it should be understood that the first element can not only be "directly connected or coupled" or "directly contacted or overlapped" with the second element, but also a third element can be "inserted" between the first and second elements, or the first and second elements can be "connected or coupled", "contacted or overlapped" with each other through a fourth element, etc. Here, the second element can be included in at least one of the two or more elements that are "connected or coupled", "contacted or overlapped", etc. with each other.

[0038] When time relative terms such as "after", "after", "next", "before", etc. are used to describe a process or operation of an element or configuration, or a flow or step in an operation, process, or manufacturing method, unless used with the terms "directly" or "immediately", these terms can be used to describe non-continuous or non-sequential processes or operations.

[0039] Furthermore, when any dimension, relative size, etc. is mentioned, even if no relevant description is specified, it should be considered that the numerical value or corresponding information (e.g., level, range, etc.) of the element or feature includes a tolerance or error range that may be caused by various factors (e.g., process factors, internal or external influences, noise, etc.). In addition, the term "may" fully encompasses all meanings of the term "can".

[0040] Various embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0041] Figure 1A and Figure 1B 1 is a plan view of a narrow viewing angle mode and a wide viewing angle mode of a switchable privacy mode when a display device 100 (eg, a semiconductor device) to which a switchable privacy mode is applied is installed in front of a passenger seat as an example according to an embodiment of the present disclosure.

[0042] like Figure 1A and Figure 1B As shown, the display device 100 capable of switching between a wide viewing angle mode and a narrow viewing angle mode may be installed in front of a passenger seat of a car.

[0043] However, the installation position of the display device 100 is not limited to the front of the passenger seat, and the display device 100 can be set in various positions such as in front of the driver's seat, behind the passenger seat, and behind the driver's seat. The installation position of the display device 100 is not limited to the car, and the display device 100 can be applied to any location requiring privacy.

[0044] like Figure 1A As shown, during the narrow viewing angle mode, the display device 100 provides an image having a brightness of at least 1% (eg, a first brightness) to the passenger, but provides an image having a brightness of less than 1% (eg, a second brightness) to the driver.

[0045] In other words, since only the view of the passenger sitting on the passenger seat is ensured, and the view of the driver sitting on the driver seat is not ensured, the privacy of the passenger sitting only on the passenger seat can be ensured. Therefore, during the narrow viewing angle mode, the image is displayed at the first viewing angle.

[0046] like Figure 1B As shown, during the wide viewing angle mode, the display device 100 provides an image having a brightness of at least 1% (eg, a first brightness) to the passenger and the driver to provide an image that can be shared by the passenger and the driver.

[0047] In other words, in the wide viewing angle mode, not only the view of the passenger sitting on the passenger seat but also the view of the driver sitting on the driver seat can be ensured. Therefore, during the wide viewing angle mode, an image is displayed at a second viewing angle greater than the first viewing angle.

[0048] Figure 2 is an exemplary diagram of the display device 100 when the display device 100 senses a touch in a touch sensing method based on self-capacitance according to an embodiment of the present disclosure.

[0049] refer to Figure 2 In the case of a touch sensing method based on self-capacitance, each touch sensor 200 provided in the display device 100 serves as both a driving touch electrode (to which a driving signal is applied) and a sensing touch electrode (which detects a sensing signal).

[0050] In other words, a driving signal is applied to each touch sensor 200 , and a sensing signal is received by the touch sensor 200 to which the driving signal is applied.

[0051] Therefore, in the self-capacitance based touch sensing method, there is no distinction between drive electrodes and sense electrodes.

[0052] In a touch sensing method based on self-capacitance, a touch sensing circuit applies a drive signal to at least one touch sensor 200, receives a sensing signal from the touch sensor 200 to which the drive signal is applied, and detects the presence or absence of a touch and / or the touch coordinates based on the capacitance change between an indicator such as a finger or a pen and the touch sensor 200 according to the received sensing signal.

[0053] refer to Figure 2 In order to transmit a driving signal and a sensing signal, each of the plurality of touch sensors 200 may be electrically connected to the pad 500 through at least one touch line 300 .

[0054] The pad 500 to which the touch wire 300 is connected may be connected to a touch sensing circuit (not shown).

[0055] The touch sensing circuit may provide a touch driving signal to at least one of the plurality of touch sensors 200 , and may detect at least one of the presence or absence of a touch and a touched position in response to the touch driving signal.

[0056] refer to Figure 2 , a plurality of touch sensors 200 may be located on a plurality of sub-pixels on a substrate.

[0057] Figure 2 The arrangement of the plurality of sub-pixels shown in FIG. 1 is merely an example and is not necessarily limited thereto.

[0058] refer to Figure 2 Each of the plurality of touch sensors 200 may have, for example, a rhombus shape in outline. In some cases, each of the plurality of touch sensors 200 may have a rectangular shape (may include a square shape), and in addition thereto, may have various shapes.

[0059] Figure 2 A touch sensing method based on self capacitance is shown, but this is only an example. The touch sensing method of the display device 100 is not necessarily limited thereto. For another example, a touch sensing method based on mutual capacitance may be used.

[0060] When the touch sensing method of the display device 100 is a mutual capacitance-based touch sensing method, a plurality of connection patterns electrically connected to at least one of the plurality of touch sensors may be included.

[0061] Figure 3 is a plan view showing a sub-pixel disposed in an active area of ​​a display device according to an embodiment of the present disclosure.

[0062] refer to Figure 3 , pixels arranged in the active area A / A of the display device may include sub-pixels of different colors for color realization of an image.

[0063] The sub-pixels may include a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B.

[0064] Although each sub-pixel may also include a white sub-pixel, Figure 3 A case where the plurality of sub-pixels include a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B is shown as an example.

[0065] The plurality of sub-pixels may include sub-pixels having different areas to implement a switchable privacy mode.

[0066] For example, on a plane defined by the first direction FD and the second direction SD, a plurality of sub-pixels including a first sub-pixel and a second sub-pixel having a smaller area than the first sub-pixel may be located in the active area A / A on the substrate.

[0067] In this way, through Figure 3 By designing differently the sizes and arrangements of the sub-pixels included in the first pixel group PG1 among the sub-pixels arranged in the active area A / A of the display device, a privacy protection mode system capable of switching between a wide viewing angle mode and a narrow viewing angle mode can be implemented.

[0068] Although there is no particular limitation on the size and arrangement of sub-pixels used to implement the switchable privacy mode, Figure 3 It is shown as an example that four first sub-pixels having a wide area and 14 second sub-pixels having a narrow area are provided in the first pixel group PG1 .

[0069] Each sub-pixel may include a pixel circuit and a light emitting element.

[0070] refer to Figure 3 , the plurality of touch sensors 200 may be disposed in at least a portion of a region other than a region where the plurality of sub-pixels are disposed. That is, the touch sensor 200 does not overlap with the sub-pixels in a plan view.

[0071] Figure 3 The illustrated plurality of touch sensors 200 may operate in a self-capacitance-based touch sensing method, may operate in a mutual-capacitance-based touch sensing method, or may operate in various touch sensing methods to which the touch sensors 200 may be applied.

[0072] Figure 3 The arrangement of the plurality of touch sensors 200 shown is an example, which shows that the plurality of touch sensors 200 are arranged in at least a portion of the area other than the area where the plurality of sub-pixels are arranged, but the embodiments of the present disclosure are not necessarily limited to such an arrangement or shape. The plurality of touch sensors 200 may cover the entire area or a portion of the active area A / A, or the touch sensor 200 may not be arranged.

[0073] Depending on the arrangement of each sub-pixel, the plurality of touch sensors 200 may have a grid shape with openings.

[0074] Depending on the setting of the lens components provided on each sub-pixel, Figure 3 Each of the plurality of touch sensors 200 may have a shape with an opening, and may have a shape with at least two openings connected to each other.

[0075] In order to improve the sensing of the touch sensor, in the case of a small-sized sub-pixel, the sub-pixel may be disposed in an opening of the touch sensor, but in the case where a relatively large-sized or rectangular sub-pixel cannot be disposed in the same opening, the touch sensor may be disposed in parallel with the long side of the sub-pixel. Since a plurality of touch sensors may be formed independently of each other according to the shape and arrangement of each sub-pixel, the respective touch sensors are electrically connected using a connection pattern (not shown).

[0076] Figure 4 is a plan view showing a sub-pixel disposed in an active area of ​​a display device according to another embodiment of the present disclosure.

[0077] refer to Figure 4 ,exist Figure 4 The active area A / A may include a plurality of black matrices 220 arranged in at least a portion of a region except a region where a plurality of sub-pixels are disposed.

[0078] refer to Figure 4 , a plurality of touch sensors 210 arranged in at least a portion of an area other than an area where a plurality of sub-pixels are arranged and a plurality of black matrices 220 arranged in at least a portion of an area other than an area where a plurality of sub-pixels are arranged may be arranged, and some areas of the plurality of touch sensors 210 and the plurality of black matrices 220 may overlap with each other. That is, the touch sensors 210 and the black matrices 220 do not overlap with the sub-pixels and the lens parts LEN. The plurality of black matrices 220 may have a grid shape with openings of different sizes and shapes according to the setting of each sub-pixel of different sizes and shapes. For the case of a sub-pixel in which the touch sensor 210 is arranged in parallel with the long side of the sub-pixel, the black matrix 220 is also arranged in parallel with the long side of the sub-pixel to cover the touch sensor 210, and the short side of the sub-pixel may not be surrounded by the black matrix 220.

[0079] However, this is merely an example, and the embodiments of the present disclosure are not necessarily limited thereto. When viewed on a plane defined by the first direction FD and the second direction SD, the touch sensor 210 and the black matrix 220 may be arranged to completely overlap each other or may be arranged not to overlap each other. Therefore, various arrangements are possible.

[0080] In addition, on a plurality of sub-pixels in the active area A / A, only the black matrix 220 may be provided, only the touch sensor 210 may be provided, or neither the black matrix 220 nor the touch sensor 210 may be provided.

[0081] Figure 5 According to an embodiment Figure 3 An enlarged plan view of area PG1.

[0082] refer to Figure 5, the display device may include a plurality of recesses 400 respectively located in a plurality of sub-pixels.

[0083] The first pixel group PG1 may include a plurality of first sub-pixels SP1 and a plurality of second sub-pixels SP2 .

[0084] Some of the sub-pixels SP1 and SP2 may emit light of different colors.

[0085] For example, the first sub-pixel SP1 may be composed of a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B, and may emit red, green, and blue light, respectively.

[0086] For example, the second sub-pixel SP2 may be composed of a red sub-pixel R, a green sub-pixel G, and a blue sub-pixel B, and may emit red, green, and blue light, respectively.

[0087] Figure 5 The arrangement of the sub-pixels SP1 and SP2 including the red sub-pixel R, the green sub-pixel G, and the blue sub-pixel B shown in the plan view of FIG. 1 is merely an example. The embodiments of the present disclosure are not necessarily limited to this arrangement, and configurations employing various combinations are conceivable.

[0088] Sub-pixels emitting light of different colors may include opening regions having different areas.

[0089] For example, the area of ​​the opening region emitting blue light may be the largest, and the area of ​​the opening region emitting red light may be the smallest.

[0090] This is because characteristics of light emitting elements included in sub-pixels emitting light of different colors may be different from each other.

[0091] However, embodiments of the present disclosure are not necessarily limited thereto, and the areas of the opening regions may be the same regardless of color.

[0092] refer to Figure 5 , the concave portion 400 disposed in the first sub-pixel SP1 may surround a portion of the opening region in the first sub-pixel SP1, and the concave portion 400 disposed in the second sub-pixel SP2 may surround the opening region in the second sub-pixel SP2.

[0093] The concave portion surrounds the second sub-pixel SP2 means that the concave portion completely surrounds the outer periphery of the opening region in the second sub-pixel SP2 when viewed on a plane defined by the first direction FD and the second direction SD.

[0094] Figure 6 According to the embodiment of the present disclosure Figure 4 An enlarged plan view of area PG2.

[0095] refer to Figure 6, the second pixel group PG2 can be regarded as also including Figure 5 The black matrix 220 in the first pixel group PG1.

[0096] exist Figure 6 In the embodiment, the plurality of sub-pixels and the concave portions respectively disposed in the plurality of sub-pixels may be aligned with the reference Figure 5 The described plurality of sub-pixels and the concave portions respectively provided in the plurality of sub-pixels are substantially the same.

[0097] Figure 7 is a plan view illustrating a display device operating method depending on a mode of a switchable privacy mode in the display device 100 according to an embodiment of the present disclosure.

[0098] Will be Figure 6 For example, the second pixel group PG2 Figure 7 The description is given and the description is used as an example to explain the switchable privacy mode. However, the description is not necessarily applicable only to the second pixel group PG2, but may be applicable to the case of the first pixel group GP1, and may also be applicable to other pixel groups.

[0099] refer to Figure 7 , the switchable privacy mode can be based on the user (e.g. Figure 1A and Figure 1B The display can be switched between a wide viewing angle mode and a narrow viewing angle mode for the convenience of passengers or drivers.

[0100] In the case of the wide viewing angle mode, in order to ensure a wide viewing angle, light may be emitted from the emission region of the first subpixel SP1 having a wider area, and light may not be emitted (OFF) from the emission region of the second subpixel SP2 having a narrower area than the first subpixel SP1.

[0101] In the case of the narrow viewing angle mode, in order to ensure a narrow viewing angle, light may not be emitted from the emission region of the first subpixel SP1 having a wider area (OFF), and light may be emitted from the emission region of the second subpixel SP2 having a narrower area than the first subpixel SP1.

[0102] When the display device 100 is installed in front of the passenger seat, in the wide viewing angle mode, not only the view of the passenger sitting in the passenger seat but also the view of the driver sitting in the driver seat can be ensured. That is, in the wide viewing angle mode, both the passenger and the driver can see the image.

[0103] In the narrow viewing angle mode, since only the view of the passenger sitting in the passenger seat is ensured, and the view of the driver sitting in the driver seat is not ensured, privacy protection can be achieved only for the passenger sitting in the passenger seat. That is, in the narrow viewing angle mode, the passenger sees the image, but the driver does not see the image.

[0104] Fig. 8A and Figure 8B are perspective views respectively illustrating a first lens component LEN1 and a second lens component LEN2 of a display device according to an embodiment of the present disclosure.

[0105] refer to Fig. 8A , the first lens part LEN1 corresponding to the first sub-pixel SP1 may have a semi-cylindrical shape having a diameter C1 in the first direction FD, a length C2 in the second direction SD, and a height C3 in the third direction TD.

[0106] In the first lens component LEN1 , a length C2 in the second direction SD may be greater than a diameter C1 in the first direction FD.

[0107] Although Fig. 8A The first lens component LEN1 has a semi-cylindrical shape, but this shape is only an example, and the embodiments of the present disclosure are not limited to this shape. Various shapes are possible depending on the shape of the opening area of ​​the first sub-pixel SP1.

[0108] For example, the height C3 in the third direction TD may be half of the diameter C1 in the first direction FD, but is not necessarily limited thereto. The height C3 in the third direction TD may be greater than or less than half of the diameter C1 in the first direction FD.

[0109] refer to Figure 8B , the second lens part LEN2 corresponding to the second sub-pixel SP2 may have a hemispherical shape having a diameter S1 in the first direction FD, a diameter S2 in the second direction SD, and a height S3 in the third direction TD.

[0110] In the second lens component LEN2, a diameter S2 in the second direction SD and a diameter S1 in the first direction FD may be the same.

[0111] Although Figure 8B The second lens component LEN2 has a hemispherical shape, but this shape is only an example, and the embodiments of the present disclosure are not necessarily limited to this shape. Various shapes are possible depending on the shape of the opening area of ​​the second sub-pixel SP2.

[0112] For example, the height S3 in the third direction TD may be half of the diameter S1 in the first direction FD, but is not necessarily limited thereto. The height C3 in the third direction TD may be greater than or less than half of the diameter S1 in the first direction FD.

[0113] Fig. 9A and Fig. 9B According to an embodiment Figure 5An enlarged plan view of an example of sub-pixels SP1 and SP2 in FIG.

[0114] In the description Fig. 9A and Fig. 9B When the first sub-pixel SP1 and the second sub-pixel SP2 are configured, the touch sensor is omitted.

[0115] refer to Fig. 9A , the first subpixel SP1 may include a first opening region OPN1 in the first subpixel SP1 and a first concave portion 410 surrounding the first opening region OPN1. The first concave portion 410 may be formed along a short side (e.g., a first side) of the first opening region OPN1 but not along a long side (e.g., a second side) of the first opening region OPN1.

[0116] However, the embodiments of the present disclosure are not necessarily limited thereto. The first recess 410 may be formed along the long sides of the first open region OPN1, may be formed to surround both the short sides and the long sides, and may be formed in various shapes. Fig. 9A It is shown as an example that the first recess 410 is formed along the short side of the first opening region OPN1 .

[0117] The first recessed portion 410 may be composed of a flat portion and an inclined portion surrounding the flat portion.

[0118] The first open region OPN1 may be surrounded by the inclined portion of the first concave portion 410 .

[0119] The light emitting region of the first subpixel SP1 may be defined by the first opening region OPN1.

[0120] That is, the light emitting region of the first subpixel SP1 may be substantially the same as the first opening region OPN1.

[0121] Substantially the same in the present disclosure may mean the same degree achieved by taking into account a slight difference due to a process error.

[0122] The first sub-pixel SP1 may include a first lens part LEN1 corresponding to the first opening area OPN1. That is, the first lens part LEN1 overlaps the first opening area OPN1.

[0123] Fig. 9A The first lens component LEN1 can be compared with the reference Fig. 8A The described first lens components LEN1 are substantially identical.

[0124] The first lens part LEN1 may cover the first open area OPN1 in the first sub-pixel SP1 and the concave portion 410 provided in the first sub-pixel SP1.

[0125] The fact that the first lens component LEN1 covers the recessed portion 410 provided in the first sub-pixel SP1 is a concept including both the case of covering the entire recessed portion 410 and the case of covering a part of the recessed portion 410 .

[0126] The first lens component LEN1 is used to improve light efficiency by changing the optical path of light emitted from the first opening area OPN1. The first lens component LEN1 may be located at a position corresponding to the first opening area OPN1, and the shape of the first lens component LEN1 may also correspond to the shape of the first opening area OPN1. That is, the shape of the first lens component LEN1 has the same shape as the first opening area OPN1. However, the shape of the first lens component LEN1 is not necessarily limited to the shape of the first opening area OPN1, and various shapes are possible.

[0127] refer to Fig. 9A , the concave portion 410 provided in the first sub-pixel SP1 may surround a portion of the first opening region OPN1 in the first sub-pixel SP1.

[0128] exist Fig. 9A In an embodiment, when viewed on a plane defined by a first direction FD and a second direction SD perpendicular to the first direction FD, a distance (e.g., a first distance) between two points (e.g., a first pair of points) at which an imaginary straight line (e.g., a first imaginary straight line) L1 passing through a center point of the first opening area OPN1 in the first subpixel SP1 and parallel to the second direction SD intersects with a boundary of the first opening area OPN1 in the first subpixel SP1 may be greater than a distance (e.g., a second distance) between two points (e.g., a second pair of points) at which an imaginary straight line (e.g., a second imaginary straight line) L2 passing through a center point of the first opening area OPN1 in the first subpixel SP1 and parallel to the first direction FD intersects with the boundary of the first opening area OPN1 in the first subpixel SP1, and a first recess 410 disposed in the first subpixel SP1 may surround two points at which an imaginary straight line passing through a center point of the first opening area OPN1 in the first subpixel SP1 and parallel to the second direction SD intersects with the boundary of the first opening area OPN1 in the first subpixel SP1.

[0129] In this specification, the center point may refer to a geometric center of a region having a random area when viewed on a plane defined by a first direction FD and a second direction SD perpendicular to the first direction FD.

[0130] For example, Fig. 9A The central point of the first opening area OPN1 in φ may represent an intersection point of two diagonal lines connecting opposite vertices of the first opening area OPN1.

[0131] The center point of the first opening region OPN1 is located inside the first opening region OPN1.

[0132] When in the above Fig. 9A When the first recess 410 is set in the embodiment, the first recess 410 widely extracts light in the second direction SD, and at the same time, the viewing angle in the first direction FD is reduced by the first lens component LEN1, while the brightness viewing angle in the second direction SD is improved, thereby realizing the wide viewing angle mode expected by the user.

[0133] refer to Fig. 9B , the second sub-pixel SP2 may include a second opening area OPN2 in the second sub-pixel SP2 and a second concave portion 420 surrounding the second opening area OPN2.

[0134] The second recessed portion 420 may be composed of a flat portion and an inclined portion surrounding the flat portion.

[0135] The second open region OPN2 may be surrounded by the inclined portion of the second concave portion 420 .

[0136] The light emitting region of the second sub-pixel SP2 may be defined by the second opening region OPN2.

[0137] That is, the light emitting area of ​​the second subpixel SP2 may be substantially the same as the second opening area OPN2.

[0138] The second sub-pixel SP2 may include a second lens part LEN2 corresponding to the second opening area OPN2. That is, the second lens part LEN2 overlaps the second opening area OPN2.

[0139] Fig. 9B The second lens component LEN2 can be compared with the reference Figure 8B The described second lens component LEN2 is substantially the same.

[0140] The second lens component LEN2 is used to improve light efficiency by changing the optical path of light emitted from the second opening area OPN2. The second lens component LEN2 can be located at a position corresponding to the second opening area OPN2, and the shape of the second lens component LEN2 can also correspond to the shape of the second opening area OPN2. That is, the shape of the second lens component LEN2 has the same shape as the second opening area OPN2. However, the shape of the second lens component LEN2 is not necessarily limited to the shape of the second opening area OPN2, and various shapes are possible.

[0141] refer to Fig. 9B , the second recess 420 disposed in the second sub-pixel SP2 may surround the second opening region OPN2 in the second sub-pixel SP2.

[0142] exist Fig. 9B In an embodiment, when viewed on a plane defined by a first direction FD and a second direction SD perpendicular to the first direction FD, a distance between two points where an imaginary straight line L3 passing through a center point of the second opening area OPN2 in the second subpixel SP2 and parallel to the first direction FD intersects with a boundary of the second opening area OPN2 in the second subpixel SP2 may be the same as a distance between two points where an imaginary straight line L4 passing through a center point of the second opening area OPN2 in the second subpixel SP2 and parallel to the second direction SD intersects with the boundary of the second opening area OPN2 in the second subpixel SP2.

[0143] When in the above Fig. 9B When the second recess 420 is set in the embodiment, since the second opening area OPN2 is surrounded by the inclined portion of the second recess 420, light extraction can be maximized, the viewing angle in the first direction FD can be reduced, and the light can be gathered to the front through the second lens component LEN2, thereby achieving the narrow viewing angle mode expected by the user.

[0144] Fig. 9C According to an embodiment Figure 5 FIG. 1 is an enlarged plan view of another example of a sub-pixel SP1.

[0145] Fig. 9C The opening region OPN1 and the first concave portion 410 in the first sub-pixel SP1 are aligned with the reference Fig. 9A The opening region OPN1 and the first concave portion 410 in the first sub-pixel SP1 are substantially the same.

[0146] refer to Fig. 9C The first lens part LEN1 may cover the opening area OPN1 in the first sub-pixel SP1 and may cover a portion of the first recess 410 provided in the first sub-pixel SP1 without covering the entire first recess 410. Therefore, a portion of the first recess 410 does not overlap with the first lens part LEN1.

[0147] When the first lens component LEN1 is designed as described above Fig. 9C In the form shown in , the first lens component LEN1 extracts light emitted through the opening area OPN1 in the first sub-pixel SP1, and light emitted from the first concave portion 410 is not extracted by the first lens component LEN1.

[0148] Therefore, since the light emitted from the first concave portion 410 is not extracted by the first lens part LEN1, the luminance efficiency is reduced, but the viewing angle in the second direction SD is increased, so that an enhanced wide viewing angle mode can be implemented.

[0149] Fig.10 According to one embodiment, Figure 6A cross-sectional view taken along line AA'.

[0150] Fig.10 It may be a view showing a plurality of sub-pixel regions in the display device according to an embodiment of the present disclosure, and may be a view showing a portion of an inactive region.

[0152] In the active region, the display device may include a first transistor on the substrate 1100 and an organic light emitting element electrically connected to the first transistor.

[0153] The first transistor may include a first active layer 1121 , a first gate electrode layer 1122 , a first source electrode layer 1123 , and a first drain electrode layer 1124 .

[0154] The organic light emitting element includes a first electrode layer 1310 , a light emitting layer 1320 , and a second electrode layer 1340 .

[0155] The first electrode layer 1310 may be an anode electrode layer, and the second electrode layer 1340 may be a cathode electrode layer, but the embodiments of the present disclosure are not limited thereto.

[0156] Specifically, the first metal pattern 1127 may be disposed on the substrate 1100 .

[0157] The first buffer layer 1110 may be disposed on the substrate 1100 and the first metal pattern 1127 , and the second buffer layer 1111 may be disposed on the first buffer layer 1110 .

[0158] The first active layer 1121 of the first transistor may be disposed on the second buffer layer 1111 .

[0159] The first gate insulating layer 1112 may be disposed on the first active layer 1121 , and the first gate electrode layer 1122 may be disposed on the first gate insulating layer 1112 .

[0160] The first interlayer insulating layer 1113 may be disposed on the first gate electrode layer 1122 , the third buffer layer 1114 may be disposed on the first interlayer insulating layer 1113 , the second gate insulating layer 1115 may be disposed on the third buffer layer 1114 , and the second interlayer insulating layer 1116 may be disposed on the second gate insulating layer 1115 .

[0161] The second metal pattern 1128 , the first source electrode layer 1123 , and the first drain electrode layer 1124 may be disposed on the second interlayer insulating layer 1116 .

[0162] The first source electrode layer 1123 and the first drain electrode layer 1124 may be disposed to be spaced apart from each other on the second interlayer insulating layer 1116 .

[0163] Each of the first source electrode layer 1123 and the first drain electrode layer 1124 may contact the first active layer 1121 through a hole formed in the first gate insulating layer 1112 , the first interlayer insulating layer 1113 , the third buffer layer 1114 , the second gate insulating layer 1115 , and the second interlayer insulating layer 1116 .

[0164] Although the first transistor may be disposed on the substrate 1100 as described above, the structure of the first transistor according to an embodiment of the present disclosure is not limited thereto.

[0165] For another example, the first gate electrode layer 1122 may be disposed on the substrate 1100, the first active layer 1121 may be disposed on the first gate electrode layer 1122, and on the first active layer 1121, the first source electrode layer 1123 may be disposed to overlap with one end of the first active layer 1121, and the first drain electrode layer 1124 may be disposed to overlap with the other end of the first active layer 1121.

[0166] An insulating layer 1210 may be provided to cover the first transistor.

[0167] The insulating layer 1210 may be made of an organic material, but the embodiments of the present disclosure are not limited thereto.

[0168] The insulating layer 1210 may include a first insulating layer 1211 , a second insulating layer 1212 , and a third insulating layer 1213 .

[0169] Specifically, a first insulating layer 1211 covering the first transistor may be provided, a second insulating layer 1212 may be provided on the first insulating layer 1211 , and a third insulating layer 1213 may be provided on the second insulating layer 1212 .

[0170] However, the insulating layer 1210 is not necessarily limited thereto. The insulating layer 1210 may be an insulating layer formed as a single layer, and thus is not limited to a multi-layer.

[0171] The insulating layer 1210 may be provided for a plurality of sub-pixels, and may include a plurality of recesses 400 respectively located in the plurality of sub-pixels.

[0172] Fig.10 An example of a case where the insulating layer 1210 is provided in the red sub-pixel R and the green sub-pixel G and includes the second concave portion 420 and the first concave portion 410 located in the red sub-pixel R and the green sub-pixel G, respectively, is shown.

[0173] The insulating layer 1210 may include a peripheral portion surrounding the recess 400 and located around the recess 400 .

[0174] The recessed portion 400 may be composed of a flat portion FLT and an inclined portion SLO surrounding the flat portion FLT and extending from the flat portion FLT.

[0175] Specifically, the second insulating layer 1212 may include a flat portion FLT, and the third insulating layer 1213 may include an inclined portion SLO. Therefore, an opening is formed through the entire thickness of the third insulating layer 1213 on the second insulating layer 1212, thereby exposing a portion of the upper surface of the second insulating layer 1212 corresponding to the flat portion FLT, and exposing a portion of the side surface of the third insulating layer 1213 corresponding to the inclined portion SLO.

[0176] However, the embodiments of the present disclosure are not necessarily limited thereto, and one insulating layer 1210 may include both the flat portion FLT and the inclined portion SLO of the recess 400 .

[0177] The flat portion FLT of the recess 400 may be a portion whose surface is parallel to the surface of the substrate 1100 , and the inclined portion SLO may be a portion surrounding the flat portion FLT and whose surface has a predetermined angle with the surface of the substrate 1100 .

[0178] That is, the surface of the inclined portion SLO may not be parallel to the surface of the substrate 1100 .

[0179] The first concave portion 410 may be composed of a first flat portion FLT1 and a first inclined portion SLO1 surrounding the first flat portion FLT1 .

[0180] The second concave portion 420 may be composed of a second flat portion FLT2 and a second inclined portion SLO2 surrounding the second flat portion FLT2 .

[0181] The insulating layer 1210 may have a contact hole spaced apart from the recess 400 .

[0182] In at least one sub-pixel region, the first electrode layer 1310 is disposed on the outer peripheral portion of the insulating layer 1210 and the concave portion 400 .

[0183] In addition, as described above, in at least one sub-pixel region, the insulating layer 1210 may include at least one contact hole spaced apart from the recess 400 , and the first transistor and the first electrode layer 1310 of the organic light emitting element may be electrically connected through the contact hole of the insulating layer 1210 .

[0184] A bank layer 1330 located on the insulating layer 1210 and including an opening region OPN in at least one sub-pixel may be provided. The bank layer 1330 is located on the third insulating layer 1213. Therefore, the bank layer 1330 includes a plurality of opening regions OPN (eg, openings) overlapping the concave portions of the second insulating layer 1213. Fig.10 As shown, each open region OPN extends into a corresponding recess of the second insulating layer 1213 .

[0185] The bank layer 1330 has an opening region OPN which exposes a portion of the upper surface of the first electrode layer 1310 in a region overlapping the recess 400 .

[0186] The opening region OPN may correspond to a portion of the flat portion FLT.

[0187] The fact that the opening area OPN corresponds to a portion of the flat portion FLT may mean that the opening area OPN overlaps a portion of the flat portion FLT in the sub-pixel.

[0188] Therefore, at least one sub-pixel may have a region where the first electrode layer 1310 does not overlap with the bank layer 1330 .

[0189] The opening region OPN may include a first opening region OPN1 and a second opening region OPN2 .

[0190] A first opening area OPN1 in a first sub-pixel among the plurality of sub-pixels may be wider than a second opening area OPN2 in a second sub-pixel among the plurality of sub-pixels.

[0191] The light emitting layer 1320 of the organic light emitting element may be disposed on the first electrode layer 1310 not overlapping the bank layer 1330 .

[0192] The light emitting layer 1320 may be disposed on a portion of the bank layer 1330 and the first electrode layer 1310 .

[0193] The second electrode layer 1340 of the organic light emitting element may be disposed on the light emitting layer 1320 .

[0194] The light emitting layer 1320 of the organic light emitting element may be formed by a deposition or coating method having flatness.

[0195] For example, the light emitting layer 1320 may be formed by a physical vapor deposition (PVD) method.

[0196] The thickness of the light emitting layer 1320 formed by this method may be thinner in a region having a predetermined angle with respect to the substrate 1100 than in a region parallel to the substrate 1100 .

[0197] Therefore, when driving the organic light emitting element, the current density can be highest in the area where the thickness of the light emitting layer 1320 is formed to be relatively thin, that is, the area corresponding to the inclined portion SLO of the recess 400, and a strong electric field can be applied in the area corresponding to the inclined portion SLO of the recess 400.

[0198] Therefore, light emission characteristics of the organic light emitting element in a region corresponding to the inclined portion SLO of the recess 400 and light emission characteristics of the organic light emitting element in a region corresponding to the flat portion FLT of the recess 400 may be different from each other, and degradation of the element may occur.

[0199] The light emitting layer 1320 may include a red organic light emitting layer 1320R disposed in the red sub-pixel R, a green organic light emitting layer 1320G disposed in the green sub-pixel G, and a blue organic light emitting layer 1320B disposed in the blue sub-pixel B.

[0200] Fig.10 A case where the red organic light emitting layer 1320R is disposed in the second sub-pixel and the green organic light emitting layer 1320G is disposed in the first sub-pixel is illustrated, but embodiments of the present disclosure are not necessarily limited to this configuration.

[0201] In the embodiment of the present disclosure, since the bank layer 1330 is provided to cover the inclined portion SLO of the recess 400 , it is possible to prevent element degradation from occurring in the region corresponding to the inclined portion SLO of the recess 400 and prevent the phenomenon that light emission characteristics differ in different regions.

[0202] However, the thickness condition of the light emitting layer 1320 in the embodiment of the present disclosure is not limited thereto, and the light emitting layer 1320 may have a corresponding thickness at each position.

[0203] The first electrode layer 1310 may include a reflective metal.

[0204] Fig.10 A configuration in which the first electrode layer 1310 is a single layer is shown. However, the embodiments of the present disclosure are not limited thereto, and the first electrode layer 1310 may be composed of a plurality of layers.

[0205] For example, when the first electrode layer 1310 is composed of a plurality of layers, at least one layer may include a reflective metal.

[0206] For example, the first electrode layer 1310 may include at least one of aluminum, neodymium, nickel, titanium, tantalum, copper, silver, and an aluminum alloy, but the embodiments of the present disclosure are not limited thereto.

[0207] The second electrode layer 1340 may include a conductive material that transmits or semi-transmits light.

[0208] For example, the second electrode layer 1340 may include at least one type of transparent conductive oxide such as indium tin oxide (ITO), indium zinc oxide (IZO), indium tin zinc oxide (ITZO), zinc oxide, and tin oxide, or may include a translucent metal such as magnesium, silver, and an alloy of magnesium and silver.

[0209] When the second electrode layer 1340 includes a semi-transparent metal, the thickness of the second electrode layer 1340 may be thinner than the thickness of the first electrode layer 1310 .

[0210] On the substrate 1100 , a first metal pattern 1127 , a second metal pattern 1128 electrically connected to the first metal pattern 1127 , and a third metal pattern 1129 on the first insulating layer 1211 may be disposed.

[0211] The first metal pattern 1127 may perform a function of a capacitor or perform a function of blocking light from the rear surface.

[0212] The second metal pattern 1128 may contact the first metal pattern 1127 through holes formed in the first buffer layer 1110 , the second buffer layer 1111 , the first gate insulating layer 1112 , the first interlayer insulating layer 1113 , the third buffer layer 1114 , the second gate insulating layer 1115 , and the second interlayer insulating layer 1116 .

[0213] The third metal pattern 1129 may contact the first source electrode layer 1123 through a hole formed in the first insulating layer 1211 , and may contact the first electrode layer 1310 through holes formed in the second insulating layer 1212 and the third insulating layer 1213 .

[0214] In other words, the third metal pattern 1129 may be used to electrically connect the first source electrode layer 1123 and the first electrode layer 1310 .

[0215] like Fig.10 As shown, the storage capacitor Cst may be disposed in the active area A / A.

[0216] The storage capacitor Cst may include a first storage capacitor electrode layer 1125 disposed at the same layer as the first gate electrode layer 1122 and a second storage capacitor electrode layer 1126 disposed on the first interlayer insulating layer 1113 , but the structure of the storage capacitor Cst according to an embodiment of the present disclosure is not limited thereto.

[0217] like Fig.10 As shown, the second storage capacitor electrode layer 1126 may form a capacitor with a second gate electrode layer 1131 of a second transistor different from the first transistor.

[0218] The second active layer 1130 of the second transistor may be disposed on the third buffer layer 1114 .

[0219] The second gate insulating layer 1115 may be disposed on the second active layer 1130 , and the second gate electrode layer 1131 may be disposed on the second gate insulating layer 1115 .

[0220] The second interlayer insulating layer 1116 may be disposed on the second gate electrode layer 1131 , and the insulating layer 1210 may be disposed on the second interlayer insulating layer 1116 .

[0221] The second source electrode layer 1132 and the second drain electrode layer 1133 may be disposed on the second interlayer insulating layer 1116 .

[0222] The second source electrode layer 1132 and the second drain electrode layer 1133 may be disposed to be spaced apart from each other on the second interlayer insulating layer 1116 .

[0223] Each of the second source electrode layer 1132 and the second drain electrode layer 1133 may contact the second active layer 1130 through a hole formed in the second interlayer insulating layer 1116 .

[0224] The encapsulation layer 1350 may be disposed as at least one layer on the second electrode layer 1340 of the organic light emitting element. Fig.10 As shown, the encapsulation layer 1350 is located between the bank layer 1330 and the lens feature LEN.

[0225] The encapsulation layer 1350 may include a first encapsulation layer 1351 disposed on the second electrode layer 1340 , a second encapsulation layer 1352 disposed on the first encapsulation layer 1351 , and a third encapsulation layer 1353 disposed on the second encapsulation layer 1352 .

[0226] As such, when the encapsulation layer 1350 is made of multiple layers, at least one layer may include an inorganic insulating material, and at least another layer may include an organic insulating material.

[0227] In an embodiment of the present disclosure, the first encapsulation layer 1351 and the third encapsulation layer 1353 may include an inorganic insulating material, and the second encapsulation layer 1352 may include an organic insulating material. However, the embodiment of the present disclosure is not limited thereto.

[0228] The encapsulation layer 1350 may be disposed on the organic light emitting element to prevent moisture or foreign matter from penetrating into the organic light emitting element.

[0229] A plurality of black matrices 220 may be disposed on the third encapsulation layer 1353 .

[0230] The black matrix 220 may be formed of a material having low reflectivity.

[0231] For example, the black matrix 220 may include carbon black, dye, or resin.

[0232] The touch interlayer insulating layer 1370 may be disposed on the third encapsulation layer 1353 and the black matrix 220 .

[0233] A plurality of touch sensors 210 may be disposed on the touch interlayer insulating layer 1370 .

[0234] Touch sensor 210 may be transparent or opaque.

[0235] The planarization layer 1380 may be disposed on the plurality of touch sensors 210 .

[0236] In the display device according to the embodiment of the present disclosure, since the planarization layer 1380 includes the lens part LEN, light captured in the substrate 1100 by total reflection or the like may be extracted, and thus a display device having excellent brightness may be provided.

[0237] The refractive index of the planarization layer 1380 may be lower than the refractive index of the lens part LEN.

[0238] As such, since the refractive index of the planarization layer 1380 is smaller than that of the lens part LEN, the moving path of the light may be adjusted to a desired direction.

[0239] The lens part LEN may include a first lens part LEN1 corresponding to the first concave portion 410 disposed in the first sub-pixel, and a second lens part LEN2 corresponding to the second concave portion 420 disposed in the second sub-pixel.

[0240] The fact that the lens part LEN corresponds to the recess 400 may mean, for example, that the lens part LEN is located at a position overlapping with the entire or partial area of ​​the recess 400 in one sub-pixel.

[0241] Since the lens parts LEN are located in the region corresponding to the concave portion 400, for example, light emitted from the light emitting layer 1320 to be released outside the display device and light emitted from the light emitting layer 1320 to be released outside the display device by being reflected by the reflective metal included in the first electrode layer 1310 located on the inclined portion SLO of the concave portion 400 can be effectively dispersed. That is, each lens part LEN overlaps the corresponding concave portion 400.

[0242] Since light scattered by the lens part LEN can be extracted to the outside of the display device without being completely reflected at an interface between the display device and external air, the brightness of the display device can be improved by the lens part LEN.

[0243] The display device may include a color filter CF between the touch buffer layer 1360 and the layer where the plurality of touch sensors 210 are provided. Fig.10 As shown, the touch sensor 210 is located on the same layer as the lens part LEN, and the color filter CF is located on the same layer as the black matrix 220. Therefore, the touch sensor 210 and the lens part LEN are located on different layers from the color filter CF and the black matrix 220.

[0244] exist Fig.10 In the embodiment of the present invention, the green color filter CF1 and the red color filter CF2 are disposed between the touch buffer layer 1360 and the layer where the plurality of touch sensors 210 are disposed.

[0245] By including the color filter CF between the touch buffer layer 1360 and the layer where the plurality of touch sensors 210 are provided, a display device having high luminance efficiency can be provided.

[0246] The display device may include a plurality of connection patterns 1400 located at a layer where the color filter CF and the black matrix 220 are disposed.

[0247] exist Fig.10 , it is described as an example that one connection pattern 1400 among the plurality of connection patterns 1400 is disposed between the green color filter CF1 and the red color filter CF2.

[0248] The connection pattern 1400 may include a first connection pattern 1410 on the touch buffer layer 1360 and a second connection pattern 1420 electrically connected to at least one of the plurality of touch sensors 210 .

[0249] The first connection pattern 1410 and the second connection pattern 1420 may contact each other through a hole formed in the touch interlayer insulating layer 1370. Fig.10 As shown, the first connection pattern 1410 is located on the same layer as the color filter CF and the black matrix 220 .

[0250] The display device may include at least one dam 1500 located outside the planarization layer 1380 .

[0251] Specifically, the display device according to the embodiment of the present disclosure may include a first dam portion 1510 located outside the encapsulation layer 1350 and a second dam portion 1520 located outside the planarization layer 1380. Fig.10 As shown, the end of the planarization layer 1380 contacts the second dam 1520. In addition, in the cross-sectional view of the display device, the first dam 1510 is closer to the substrate 1100 than the second dam 1520 and is located between the second dam 1520 and the bank layer 1330.

[0252] In this specification, the first dam portion 1510 and the second dam portion 1520 represent a lower dam portion and an upper dam portion, respectively.

[0253] Fig.10 A configuration is shown in which the dam 1500 includes a first dam 1510 and a second dam 1520. However, the embodiments of the present disclosure are not limited thereto, and the number of the dam 1500 may be appropriately changed according to the size of the display device.

[0254] also, Fig.10 A configuration is shown in which the first dam 1510 has two partition walls and the second dam 1520 has one partition wall. However, the embodiments of the present disclosure are not limited thereto, and the dam may have various numbers of partition walls.
