Description

Technical Field

[0001] Aspects of embodiments of the present disclosure relate to a display device that provides visual information. Background Art

[0002] With the development of information technology, the importance of display devices, which are connecting media between users and information, has become prominent. For example, the use of display devices such as liquid crystal display (LCD) devices, organic light emitting display (OLED) devices, plasma display panel (PDP) devices, or quantum dot display devices is increasing.

[0003] Typically, display devices are manufactured to provide a wide viewing angle, but for various reasons such as privacy and information protection, it may be desirable to limit the viewing angle. For example, it may be desirable for devices such as ATMs of financial institutions, portable computers, and tablet PCs to have a viewing angle that is limited in the left-right direction or the up-down direction to protect the privacy of the user.

[0004] When the display device is applied to an automobile display device and the display device has a wide viewing angle, the image displayed on the display device may reduce the driver's attention. Further, the image displayed on the display device may be reflected from the front windshield of the automobile and may interfere with the driver's operation. Accordingly, it may be desirable to limit the viewing angle of the display device in the left-right direction or the up-down direction.

[0005] The above information disclosed in this Background section is for enhancement of understanding of the background of the present disclosure and therefore it may contain information that does not constitute prior art. Summary of the invention

[0063] Hereinafter, embodiments will be described in more detail with reference to the accompanying drawings, in which the same reference numerals always refer to the same elements. However, the present disclosure may be implemented in various different forms and should not be construed as being limited to the embodiments illustrated herein. On the contrary, these embodiments are provided as examples so that the present disclosure will be thorough and complete, and will fully convey the aspects and features of the present disclosure to those skilled in the art. Accordingly, processes, elements and techniques that are unnecessary for those of ordinary skill in the art to fully understand the aspects and features of the present disclosure may not be described. Unless otherwise stated, the same reference numerals represent the same elements throughout the drawings and written descriptions, and therefore, their redundant descriptions may not be repeated.

[0064] When a certain embodiment can be implemented differently, the specific process order may be different from the described order. For example, two processes described successively may be performed simultaneously or substantially simultaneously or in the reverse order of the described order.

[0065] In the accompanying drawings, for the sake of clarity, the relative size, thickness and ratio of elements, layers and regions may be exaggerated and / or simplified. For ease of explanation, spatial relative terms such as "below", "below", "lower", "below", "above" and "upper" can be used in this article to describe the relationship between an element or feature and another (some) element or feature as illustrated in each figure. It will be understood that, in addition to the orientation depicted in each figure, the spatial relative terms are intended to cover the different orientations of the device in use or in operation. For example, if the device in each figure is turned over, the element described as "below" or "below" or "below" of other elements or features will be oriented "above" other elements or features. Therefore, the example terms "below" and "below" can cover both the orientation above and below. The device can be oriented in other ways (for example, rotated 90 degrees or according to other orientations), and the spatial relative descriptors used in this article should be interpreted accordingly.

[0066] In the drawings, the x-axis, y-axis, and z-axis are not limited to the three axes of the rectangular coordinate system and can be interpreted in a broader sense. For example, the x-axis, y-axis, and z-axis can be perpendicular or substantially perpendicular to each other, or can represent directions that are not perpendicular to each other and are different from each other.

[0067] It will be understood that although the terms "first", "second", "third", etc. may be used herein to describe various elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms are used to distinguish one element, component, region, layer or section from another element, component, region, layer or section. Therefore, without departing from the spirit and scope of the present disclosure, the first element, component, region, layer or section described below may be referred to as a second element, component, region, layer or section.

[0068] It will be understood that when an element or layer is referred to as being "on," "connected to," or "coupled to" another element or layer, it may be directly on, directly connected to, or directly coupled to the other element or layer, or there may be one or more intervening elements or layers. Similarly, when a layer, region, or element is referred to as being "electrically connected to" another layer, region, or element, it may be directly electrically connected to the other layer, region, or element, and / or may be indirectly electrically connected to the other layer, region, or element with one or more intervening layers, regions, or elements therebetween. Additionally, it will be understood that when an element or layer is referred to as being "between" two elements or layers, it may be the only element or layer between the two elements or layers, or there may also be one or more intervening elements or layers.

[0069] The terms used in this article are for the purpose of describing a specific embodiment, and are not intended to limit the present disclosure. As used in this article, the singular form "one" is intended to also include plural forms, unless the context clearly indicates otherwise. It will be further understood that when used in this specification, the terms "include", "comprise" and "have" and their variants specify the existence of the stated features, wholes, steps, operations, elements and / or parts, but do not exclude the existence or addition of one or more other features, wholes, steps, operations, elements, parts and / or their groups. As used in this article, the term "and / or" includes any and all combinations of one or more of the associated listed items. For example, the statement "A and / or B" means A, B or A and B. When after the element list, the statement such as "at least one of ..." modifies the entire element list without modifying the single element in the list. For example, the statement "at least one of a, b and c" and "at least one of the group consisting of a, b and c" represent only a, only b, only c, a and b both, a and c both, b and c both, a, b and c all and their variants.

[0070] As used herein, the terms "substantially," "approximately," and the like are used as terms of approximation rather than as terms of degree, and are intended to take into account the inherent deviations of measurements or calculations that one of ordinary skill in the art would recognize. Further, when describing embodiments of the present disclosure, the use of "may" refers to "one or more embodiments of the present disclosure." As used herein, the terms "use," "using," and "being used" may be considered synonymous with the terms "utilize," "being utilized," and "being utilized," respectively.

[0071] Unless otherwise defined, all terms (including technical and scientific terms) used in this article have the same meaning as those commonly understood by ordinary technicians in the field to which the present disclosure belongs. It will be further understood that terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant field and / or this specification, and should not be interpreted in an idealized or overly formal sense unless explicitly defined in this article.

[0072] Figure 1 is a plan view illustrating a display device according to an embodiment of the present disclosure.

[0073] As used herein, a plane may be defined by a first direction DR1 and a second direction DR2 intersecting the first direction DR1. For example, the first direction DR1 and the second direction DR2 may be perpendicular or substantially perpendicular to each other. The first direction DR1 may refer to a left-right direction (e.g., a horizontal direction) in a plan view. In other words, one side of the first direction DR1 may refer to a left direction in a plan view, and the other side of the first direction DR1 may refer to a right direction in a plan view. The second direction DR2 may refer to an up-down direction (e.g., a vertical direction) in a plan view. In other words, one side of the second direction DR2 may refer to an upward direction in a plan view, and the other side of the second direction DR2 may refer to a downward direction in a plan view. A direction perpendicular to the plane (or in other words, a thickness direction of the display device DD1) may be a third direction DR3. In other words, the third direction DR3 may be perpendicular to or substantially perpendicular to each of the first direction DR1 and the second direction DR2. The third direction DR3 may refer to a front direction of the display device DD1.

[0074] refer to Figure 1 , the display device DD1 according to an embodiment of the present disclosure may include a substrate SUB, a group pixel GPX, a first light blocking pattern LBP1, and a second light blocking pattern LBP2.

[0075] The substrate SUB may include a display area DA and a non-display area NDA. The display area DA may be defined as an area that displays an image by generating light or by adjusting the transmittance of light provided from an external light source. A plurality of group pixels GPX may be disposed in the display area DA. The group pixels GPX may generate light according to a driving signal. The group pixels GPX may be repeatedly disposed on the substrate SUB in the display area DA along a first direction DR1 and a second direction DR2. Each of the group pixels GPX may include a first pixel (e.g., Figure 2 The first pixel PX1 and the second pixel (eg, Figure 2 The second pixel PX2). Figure 2 and Figure 3 Give a more detailed description thereof.

[0076] The non-display area NDA may be defined as an area where no image is displayed. For example, the non-display area NDA may completely surround the display area DA (e.g., around its periphery). A driving chip and a plurality of pads for providing a driving signal to the group pixel GPX may be disposed in the non-display area NDA.

[0077] In an embodiment, the display area DA may have a rectangular planar shape. For example, the length of the display area DA in the first direction DR1 (e.g., left-right direction) is greater than the length of the display area DA in the second direction DR2 (e.g., up-down direction). As another example, the length of the display area DA in the second direction DR2 (e.g., up-down direction) is greater than the length of the display area DA in the first direction DR1 (e.g., left-right direction). However, the present disclosure is not limited thereto. For example, the display area DA may have one of a square planar shape, a circular planar shape, and an elliptical planar shape.

[0078] The display area DA may include a first display area DA1 , a second display area DA2 , and a third display area DA3 .

[0079] The first display area DA1 may be spaced apart from the second display area DA2 in the first direction DR1 with the third display area DA3 interposed therebetween. For example, the first display area DA1 may be adjacent to the left side of the non-display area NDA in the first direction DR1. In other words, the first display area DA1 may be located on the left side of the display area DA. The first light shielding pattern LBP1 may be disposed in the first display area DA1. The first light shielding pattern LBP1 may be repeatedly disposed along the second direction DR2. The first light shielding patterns LBP1 may be spaced apart from each other in the second direction DR2. Each of the first light shielding patterns LBP1 may extend in the first direction DR1.

[0080] The second display area DA2 may be spaced apart from the first display area DA1 in the first direction DR1 and the third display area DA3 may be interposed therebetween. For example, the second display area DA2 may be adjacent to the right side of the non-display area NDA in the first direction DR1. In other words, the second display area DA2 may be located on the right side of the display area DA. The second light shielding pattern LBP2 may be disposed in the second display area DA2. The second light shielding pattern LBP2 may be repeatedly disposed along the first direction DR1. The second light shielding patterns LBP2 may be spaced apart from each other in the first direction DR1. Each of the second light shielding patterns LBP2 may extend in the second direction DR2.

[0081] The third display area DA3 may be disposed between the first display area DA1 and the second display area DA2 in a plan view. For example, the third display area DA3 may be located at the center of the display area DA (e.g., therein or on it). In an embodiment, the first light shielding pattern LBP1 and the second light shielding pattern LBP2 may be spaced apart from the third display area DA3 in a plan view. In other words, the first light shielding pattern LBP1 and the second light shielding pattern LBP2 may not be disposed in the third display area DA3.

[0082] like Figure 1As illustrated in , the substrate SUB may include three display areas (e.g., first to third display areas DA1, DA2, and DA3). However, the present disclosure is not limited thereto. For example, the substrate SUB may include two display areas. In this case, the substrate SUB may include a first display area DA1 on which a first light shielding pattern LBP1 is disposed and a second display area DA2 on which a second light shielding pattern LBP2 is disposed. The first display area DA1 and the second display area DA2 may be adjacent to each other in the first direction DR1. As another example, the substrate SUB may include four or more display areas.

[0083] In an embodiment, each of the first light shielding pattern LBP1 and the second light shielding pattern LBP2 may include an organic material including a light shielding material having a black color. For example, the light shielding material may include a black pigment, a black dye, and / or carbon black, etc. These may be used alone or in any suitable combination with each other.

[0084] Display devices can generally be manufactured to provide a wide viewing angle, but depending on the application, it may be desirable to limit the viewing angle. For example, when the display device is applied to an automobile display device, if the display device has a wide viewing angle, the image displayed on the display device may reduce the driver's attention. In addition, the image displayed on the display device may be reflected from the front windshield of the automobile and may interfere with the driver's operation.

[0085] The display device DD1 according to an embodiment of the present disclosure may include light shielding patterns LBP1 and LBP2 that block light incident at an angle greater than a specific angle (e.g., a predetermined angle), so that the viewing angle of the display device DD1 can be adjusted. In an embodiment, the display device DD1 can be applied to a car display device. In this case, the driver's seat may be located at (e.g., in or on) the front direction (e.g., the third direction DR3) of the first display area DA1, and the passenger seat may be located at (e.g., in or on) the right direction of the first display area DA1. In addition, the passenger seat may be located at (e.g., in or on) the front direction of the second display area DA2, and the driver's seat may be located at (e.g., in or on) the left direction of the second display area DA2.

The first light emitting layer EML1 may be disposed on the first pixel electrode PE1, the third light emitting layer EML3 may be disposed on the third pixel electrode PE3, and the fourth light emitting layer EML4 may be disposed on the fourth pixel electrode PE4. The first light emitting layer EML1 may overlap with the first light emitting area EA1-PX1 of the first pixel PX1. The third light emitting layer EML3 may overlap with the third light emitting area EA3-PX1 of the first pixel PX1. The fourth light emitting layer EML4 may overlap with the first light emitting area EA1-PX2 of the second pixel PX2. For example, the third light emitting layer EML3 may include an organic material that emits blue light. Each of the first light emitting layer EML1 and the fourth light emitting layer EML4 may include an organic material that emits red light. However, the present disclosure is not limited thereto.

[0140] The common electrode CE may be disposed on the pixel defining layer PDL, the first light emitting layer EML1, the third light emitting layer EML3, and the fourth light emitting layer EML4. Accordingly, the 1st-3rd light emitting element LD1-3 including the third pixel electrode PE3, the third light emitting layer EML3, and the common electrode CE may be formed. In addition, the 2nd-1st light emitting element LD2-1 including the fourth pixel electrode PE4, the fourth light emitting layer EML4, and the common electrode CE may be formed.

[0141] The encapsulation layer TFE may be disposed on the common electrode CE, and the light control layer LCL may be disposed on the encapsulation layer TFE. The light control layer LCL may include a second light shielding pattern LBP2 and a transmissive pattern TRP. The transmissive pattern TRP may surround the second light shielding pattern LBP2 (e.g., around its periphery). Light emitted from the 1-1st light emitting element LD1-1, the 1-3rd light emitting element LD1-3, and the 2-1st light emitting element LD2-1 may pass through the transmissive pattern TRP.

[0142] The second light-shielding pattern LBP2 may be repeatedly disposed along the first direction DR1 and may be spaced apart from each other by a distance (e.g., a predetermined distance). In an embodiment, the second light-shielding pattern LBP2 may be disposed in the same layer as that of the first light-shielding pattern LBP1. In other words, the first light-shielding pattern LBP1 and the second light-shielding pattern LBP2 may include the same material as each other and may be formed by the same process as each other. By forming the first light-shielding pattern LBP1 and the second light-shielding pattern LBP2 together concurrently or substantially simultaneously through one process, the process efficiency for manufacturing the display device DD1 may be improved. For example, each of the first light-shielding pattern LBP1 and the second light-shielding pattern LBP2 may be disposed at (e.g., therein or on) the light-control layer LCL.

[0143] In an embodiment, the second height H2 of the second light shielding pattern LBP2 may be equal to or substantially equal to the first height H1 of the first light shielding pattern LBP1. The second height H2 may refer to a straight line distance from the upper surface of the encapsulation layer TFE to the upper surface of the second light shielding pattern LBP2 in the third direction DR3. For example, the second height H2 of the second light shielding pattern LBP2 may be about 40 micrometers to about 48 micrometers.

[0144] In an embodiment, each of the second light-shielding patterns LBP2 includes an organic material including a light-shielding material having a black color. Accordingly, the second light-shielding pattern LBP2 may selectively block some of the light emitted from the first pixel PX1. For example, the second light-shielding pattern LBP2 may selectively block some of the light emitted from the 1-1th light-emitting element LD1-1 and the 1-3th light-emitting element LD1-3. In other words, the second light-shielding pattern LBP2 may adjust the viewing angle of the display device DD1 by selectively absorbing some of the light emitted from the 1-1th light-emitting element LD1-1 and the 1-3th light-emitting element LD1-3. The second light-shielding pattern LBP2 may adjust the viewing angle in the first direction DR1 (e.g., the left-right direction). In more detail, the second light-shielding pattern LBP2 may adjust the viewing angle in the left direction or the right direction. Hereinafter, as a representative example, the case where the second light-shielding pattern LBP2 adjusts the viewing angle in the left direction may be described in more detail.

[0145] The second light-shielding pattern LBP2 may not block light emitted from the second pixel PX2 and traveling in the left direction. For example, the second light-shielding pattern LBP2 may not block light emitted from the 2-1st light emitting element LD2-1 and traveling in the left direction.

[0146] In an embodiment, the second light shielding pattern LBP2 may be spaced apart from the first light emitting element LD1 and the second light emitting element LD2 in a plan view. In addition, the second light shielding pattern LBP2 may overlap the pixel defining layer PDL in a plan view. For example, Figure 5 and Figure 6 As illustrated in FIG. 1 , the second light blocking pattern LBP2 may be spaced apart from the 1-1th light emitting element LD1 - 1 , the 1-3th light emitting element LD1 - 3 , and the 2-1st light emitting element LD2 - 1 in a plan view.

[0147] Accordingly, compared with a case where the second light blocking pattern LBP2 overlaps the first light emitting element LD1 and the second light emitting element LD2 in a plan view, the brightness of the display device DD1 may be relatively improved.

[0148] like Figure 5 As illustrated in FIG. 1 , the second width W2 of the second light-shielding pattern LBP2 may be greater than the first width W1 of the first light-shielding pattern LBP1. Here, the second width W2 may refer to the length of the second light-shielding pattern LBP2 in the first direction DR1, and the first width W1 may refer to the length of the first light-shielding pattern LBP1 in the second direction DR2. However, the present disclosure is not limited thereto.

[0149] In an embodiment, Figure 5 As shown in FIG. 1 , the pixel defining layer PDL disposed between adjacent light emitting elements that emit light of different colors from each other may overlap with one second light shielding pattern LBP2 in a plan view. For example, the pixel defining layer PDL disposed between the 2-1st light emitting element LD2-1 and the 1-3rd light emitting element LD1-3 may overlap with one second light shielding pattern LBP2 in a plan view. However, the present disclosure is not limited thereto.

[0150] In another embodiment, if Figure 6 As illustrated in FIG, a pixel defining layer PDL disposed between adjacent light emitting elements that emit light of different colors from each other may overlap with a plurality of second light shielding patterns LBP2' in a plan view. For example, a pixel defining layer PDL disposed between the 2-1st light emitting element LD2-1 and the 1-3rd light emitting element LD1-3 may overlap with two second light shielding patterns LBP2' in a plan view. However, the present disclosure is not limited thereto. A pixel defining layer PDL disposed between adjacent light emitting elements that emit light of different colors from each other may overlap with three or more second light shielding patterns LBP2' in a plan view.

[0151] Figure 7 yes Figure 1 An enlarged floor plan of area 'C'. Figure 8 It is along Figure 7 The cross-sectional view taken along line III-III' of FIG. Figure 4 and Figure 5 Redundant description of components that are identical or substantially identical to components of the described display device DD1.

[0152] refer to Figure 7 , the display device DD1 according to an embodiment of the present disclosure may include a substrate SUB and a group pixel GPX in the third display area DA3.

[0153] The group pixels GPX may be repeatedly arranged on the substrate SUB in the third display area DA3 along the first direction DR1 and the second direction DR2. Each of the group pixels GPX may include a first pixel PX1 and a second pixel PX2. For example, the first pixel PX1 may correspond to a left pixel of the group pixel GPX, and the second pixel PX2 may correspond to a right pixel of the group pixel GPX.

[0154] The first light shielding pattern and the second light shielding pattern may be spaced apart from the third display area DA3 in a plan view. In other words, the first light shielding pattern and the second light shielding pattern may not be disposed on the substrate SUB in the third display area DA3.

[0155] refer to Figure 8 According to an embodiment of the present disclosure, the display device DD1 may include a substrate SUB, a buffer layer BUF, a first thin film transistor TR1, a third thin film transistor TR3, a fourth thin film transistor TR4, a gate insulating layer GI, an interlayer insulating layer ILD, a through hole insulating layer VIA, a 1-1th light emitting element LD1-1, a 1-3th light emitting element LD1-3, a 2-1th light emitting element LD2-1, a pixel defining layer PDL, an encapsulation layer TFE and a light control layer LCL in a third display area DA3.

[0156] The light control layer LCL may be disposed on the encapsulation layer TFE. The light control layer LCL may include (e.g., may only include) a transmissive pattern TRP in the third display area DA3. In other words, the light control layer LCL may not include a light shielding pattern in the third display area DA3. Light emitted from the 1-1th light emitting element LD1-1, the 1-3th light emitting element LD1-3, and the 2-1st light emitting element LD2-1 may pass through the transmissive pattern TRP.

[0157] Figures 9 to 11 It is along Figure 4 For example, Fig. 9 and Fig.10is a cross-sectional view illustrating a display device DD1 driven in a first mode, and Fig.11 is a cross-sectional view illustrating the display device DD1 driven in the second mode. The first mode may be defined as a mode to achieve a wide viewing angle, and the second mode may be defined as a mode to achieve a narrow viewing angle.

[0158] refer to Figure 4 and Fig. 9 In an embodiment, when the display device DD1 is driven in the first mode, in the second display area DA2, each of the first light emitting element LD1 of the first pixel PX1 and the second light emitting element LD2 of the second pixel PX2 may emit light. For example, when the display device DD1 is driven in the first mode, in the second display area DA2, each of the 1-1 light emitting element LD1-1, the 1-3 light emitting element LD1-3, and the 2-1 light emitting element LD2-1 may emit light.

[0159] For example, the second display area DA2 may be located on the right side of the display area (eg, Figure 1 When the display device DD1 is applied to an automobile display device, a passenger seat may be located in a front direction of the second display area DA2 (e.g., in or on it), and a driver's seat may be located in a left direction of the second display area DA2 (e.g., in or on it).

[0160] The first light emitting element LD1 may emit a first left light PX1-LL propagating in the left direction and a first front light PX1-LF propagating in the front direction. For example, each of the 1-1 light emitting element LD1-1 and the 1-3 light emitting element LD1-3 may emit the first left light PX1-LL and the first front light PX1-LF. The first light emitting element LD1 may further emit a first right light propagating in the right direction (for example, Fig.21 The first right light PX1-LR), but this will be described in more detail below.

[0161] Similarly, the second light emitting element LD2 may emit a second left light PX2-LL propagating in the left direction and a second front light PX2-LF propagating in the front direction. For example, the 2-1st light emitting element LD2-1 may emit a second left light PX2-LL and a second front light PX2-LF. The second light emitting element LD2 may further emit a second right light propagating in the right direction (for example, Fig.21 The second right light PX2-LR), but this will be described in more detail below.

[0162] The second light-shielding pattern LBP2 may absorb a portion of the light emitted from the first light-emitting element LD1. In more detail, the second light-shielding pattern LBP2 may absorb the first left light PX1-LL propagating in the left direction at an angle greater than the first angle AGL1. In other words, when the angle between an imaginary straight line extending perpendicular or substantially perpendicular to the first light-emitting element LD1 and the direction in which the first left light PX1-LL emitted from the first light-emitting element LD1 propagates is greater than the first angle AGL1, the first left light PX1-LL may be absorbed by the second light-shielding pattern LBP2. For example, the first angle AGL1 may be about 45 degrees.

[0163] On the other hand, the second light blocking pattern LBP2 may not absorb the second left light PX2 -LL emitted from the second light emitting element LD2 .

[0164] When the display device DD1 is driven in the first mode (e.g., wide viewing angle mode), the driver located at the left direction of the second display area DA2 (e.g., in or on it) can view the second left light PX2-LL. Accordingly, the driver can view the image displayed in the second display area DA2. In addition, the passenger located at the front direction of the second display area DA2 (e.g., in or on it) can view the first front light PX1-LF and the second front light PX2-LF. Accordingly, the passenger can view the image displayed in the second display area DA2.

[0165] refer to Figure 4 and Fig.10 In another embodiment, when the display device DD1 is driven in the first mode, in the second display area DA2, the first light emitting element LD1 of the first pixel PX1 may not emit light, and in the second display area DA2, the second light emitting element LD2 of the second pixel PX2 may emit light. For example, when the display device DD1 is driven in the first mode, in the second display area DA2, each of the 1-1th light emitting element LD1-1 and the 1-3th light emitting element LD1-3 may not emit light, and in the second display area DA2, the 2-1th light emitting element LD2-1 may emit light.

[0166] The second light emitting element LD2 may emit second left light PX2 -LL traveling in the left direction and second front light PX2 -LF traveling in the front direction.

[0167] When the display device DD1 is driven in the first mode (e.g., wide viewing angle mode), the driver located at the left direction of the second display area DA2 (e.g., in or on it) can view the second left light PX2-LL. Accordingly, the driver can view the image displayed in the second display area DA2. In addition, the passenger located at the front direction of the second display area DA2 (e.g., in or on it) can view the second front light PX2-LF. Accordingly, the passenger can view the image displayed in the second display area DA2.

[0168] refer to Figure 4 and Fig.11 , when the display device DD1 is driven in the second mode (e.g., the narrow viewing angle mode), in the second display area DA2, the first light emitting element LD1 of the first pixel PX1 may emit light, and in the second display area DA2, the second light emitting element LD2 of the second pixel PX2 may not emit light. For example, when the display device DD1 is driven in the second mode, in the second display area DA2, each of the 1-1th light emitting element LD1-1 and the 1-3th light emitting element LD1-3 may emit light, and in the second display area DA2, the 2-1th light emitting element LD2-1 may not emit light.

[0169] The first light emitting element LD1 may emit first left light PX1 -LL traveling in a left direction and first front light PX1 -LF traveling in a front direction.

[0170] The second light-shielding pattern LBP2 may absorb a portion of the light emitted from the first light-emitting element LD1. In more detail, the second light-shielding pattern LBP2 may absorb the first left light PX1-LL propagating in the left direction at an angle greater than the first angle AGL1. In other words, when the angle between an imaginary straight line extending perpendicular or substantially perpendicular to the first light-emitting element LD1 and the direction in which the first left light PX1-LL emitted from the first light-emitting element LD1 propagates is greater than the first angle AGL1, the first left light PX1-LL may be absorbed by the second light-shielding pattern LBP2. Accordingly, the second light-shielding pattern LBP2 may adjust the viewing angle in the left direction. For example, the first angle AGL1 may be approximately 45 degrees.

[0171] In other words, when the display device DD1 is driven in the second mode (e.g., narrow viewing angle mode), the driver located at the left direction of the second display area DA2 (e.g., therein or on it) cannot view the first left light PX1-LL propagating at an angle greater than the first angle AGL1. Accordingly, the driver cannot view the image displayed in the second display area DA2. As a result, the image displayed in the second display area DA2 may not reduce the driver's attention while driving. On the other hand, the passenger located at the front direction of the second display area DA2 (e.g., therein or on it) can view the first front light PX1-LF. Accordingly, the passenger can view the image displayed in the second display area DA2.

[0172] Fig.12 is a cross-sectional view of a display device according to a comparative example. Fig.13 It is along Figure 4 A cross-sectional view taken along line II-II'.

[0173] refer to Fig.12 According to the comparative example, the display device DD' may include a through hole insulating layer VIA', a pixel electrode PE', a light emitting layer EML', a pixel defining layer PDL', an encapsulation layer TFE' and a light control layer LCL'. Fig.12 , but the display device DD' may further include a common electrode disposed on the pixel defining layer PDL' and the light emitting layer EML'. The display device DD' may be the same as the above reference except that the height H' of the light shielding pattern LBP' may be different, the width W' of the light shielding pattern LBP' may be different, and the light shielding pattern LBP' overlaps with the light emitting layer EML' in a plan view. Figure 5 The display devices DD1 described are identical or substantially identical.

[0174] The light control layer LCL' may be disposed on the encapsulation layer TFE'. The light control layer LCL' may include a light shielding pattern LBP' and a transmissive pattern TRP'. The transmissive pattern TRP' may surround the light shielding pattern LBP' (eg, around its periphery). Light emitted from the light emitting layer EML' may pass through the transmissive pattern TRP'.

[0175] The light blocking patterns LBP' may be repeatedly disposed along the first direction DR1 and spaced apart from each other by a suitable distance (eg, a predetermined distance). For example, a height H' of the light blocking pattern LBP' may be about 28 micrometers to 33 micrometers.

[0176] Each of the light shielding patterns LBP' may include an organic material including a light shielding material having a black color. Accordingly, the light shielding pattern LBP' may selectively block some of the light emitted from the light emitting layer EML'. In more detail, the light shielding pattern LBP' may absorb left light propagating in the left direction at an angle greater than the comparison angle AGLC. In other words, when the angle between an imaginary straight line extending perpendicular to the light emitting layer EML' and the direction in which the left light emitted from the light emitting layer EML' propagates is greater than the comparison angle AGLC, the left light may be absorbed by the light shielding pattern LBP'. For example, the comparison angle AGLC may be approximately 45 degrees.

[0177] Some of the light blocking patterns LBP' may overlap the light emitting layer EML' in a plan view.

[0178] refer to Fig.13 The display device DD1 according to an embodiment of the present disclosure may include a through hole insulating layer VIA, a third pixel electrode PE3, a third light emitting layer EML3, a pixel defining layer PDL, an encapsulation layer TFE, and a light control layer LCL. The display device DD1 may further include a common electrode (e.g., Figure 5 common electrode CE).

[0179] The light control layer LCL may be disposed on the encapsulation layer TFE. The light control layer LCL may include a second light shielding pattern LBP2 and a transmissive pattern TRP. The transmissive pattern TRP may surround the second light shielding pattern LBP2 (e.g., around its periphery). Light emitted from the third light emitting layer EML3 may pass through the transmissive pattern TRP. The second light shielding patterns LBP2 may be repeatedly disposed along the first direction DR1 and may be spaced apart from each other by a suitable distance (e.g., a predetermined distance).

[0180] In an embodiment, the second height H2 of the second light blocking pattern LBP2 may be greater than Fig.12 The second height H2 may be about 40 micrometers to about 48 micrometers, for example.

[0181] Each of the second light-shielding patterns LBP2 may include an organic material including a light-shielding material having a black color. Accordingly, the second light-shielding pattern LBP2 may selectively block some of the light emitted from the third light-emitting layer EML3. In more detail, the second light-shielding pattern LBP2 may absorb the left light propagating in the left direction at an angle greater than the first angle AGL1. In other words, when the angle between an imaginary straight line extending perpendicular or substantially perpendicular to the third light-emitting layer EML3 and the direction in which the left light emitted from the third light-emitting layer EML3 propagates is greater than the first angle AGL1, the left light may be absorbed by the second light-shielding pattern LBP2. For example, the first angle AGL1 may be approximately 45 degrees.

[0182] The second light blocking pattern LBP2 may be spaced apart from the third light emitting layer EML3 in a plan view.

[0183] Fig.14 Graphics Fig.12 The relationship between viewing angle and brightness in a display device. Fig.15 and Fig.16 Graphics Fig.13 The relationship between viewing angle and brightness in a display device.

[0184] In the following, reference will be made to Fig.12 , Fig.13 , Fig.14 , Fig.15 and Fig.16 Some embodiments of the present disclosure are described in more detail.

[0185] The luminance according to the viewing angle was measured in the display devices of Comparative Example 1, Comparative Example 2, Example 1, Example 2, Example 3, and Example 4. The viewing angle may refer to the angle between an imaginary straight line extending perpendicularly or substantially perpendicularly to the light emitting layer (e.g., the light emitting element) and the direction in which light emitted from the light emitting layer propagates to the left.

[0186] The display devices of Examples 1 and 2 (eg, Fig.13 The display device DD1 of Example 1 includes a second light shielding pattern LBP2 spaced apart from the third light emitting layer EML3 in a plan view. The second width W2 of the second light shielding pattern LBP2 is about 17 micrometers. The in-plane separation distance DPO between the edge of the third light emitting layer EML3 and the second light shielding pattern LBP2 is about 1 micrometer. The second height H2 of the second light shielding pattern LBP2 of the display device of Example 1 is about 40 micrometers. The second height H2 of the second light shielding pattern LBP2 of the display device of Example 2 is about 44 micrometers.

[0187] The display devices of Examples 3 and 4 (eg, Fig.13 The display device DD1 of Example 3 includes a second light shielding pattern LBP2 spaced apart from the third light emitting layer EML3 in a plan view. The second width W2 of the second light shielding pattern LBP2 is about 14 micrometers. The in-plane separation distance DPO between the edge of the third light emitting layer EML3 and the second light shielding pattern LBP2 is about 4 micrometers. The second height H2 of the second light shielding pattern LBP2 of the display device of Example 3 is about 45 micrometers. The second height H2 of the second light shielding pattern LBP2 of the display device of Example 4 is about 48 micrometers.

[0188] The display devices of Comparative Examples 1 and 2 (for example, Fig.12The display device DD') includes a light shielding pattern LBP' overlapping the light emitting layer EML' in a plan view. The width W' of the light shielding pattern LBP' is about 4 micrometers. The in-plane separation distance DPO' between the edge of the light shielding pattern LBP' overlapping the light emitting layer EML' and the light emitting layer EML' is about 5.5 micrometers.

[0189] The height H' of the light shielding pattern LBP' of the display device of Comparative Example 1 is about 28 micrometers. The height H' of the light shielding pattern LBP' of the display device of Comparative Example 2 is about 33 micrometers.

[0190] like Fig.14 , Fig.15 and Fig.16 As illustrated in , based on the brightness in the front direction (e.g., the direction in which the viewing angle is approximately 0 degrees) of the display devices of Examples 1, 2, 3, and 4, the brightness in the front direction of the display devices of Comparison Examples 1 and 2 was measured to have a value of approximately 83.7%.

[0191] When the viewing angle is about 10 degrees, the brightness of the display device of Comparative Example 1 is measured to have a value of about 66.7%, and the brightness of the display device of Comparative Example 2 is measured to have a value of about 63.7%. When the viewing angle is about 10 degrees, the brightness of the display device of Example 1 is measured to have a value of about 77.5%, and the brightness of the display device of Example 2 is measured to have a value of about 76.1%. When the viewing angle is about 10 degrees, the brightness of the display device of Example 3 is measured to have a value of about 87.5%, and the brightness of the display device of Example 4 is measured to have a value of about 87.8%.

[0192] When the viewing angle is about 45 degrees, the luminance of the display devices of Comparative Example 1, Comparative Example 2, Example 1, Example 2, Example 3, and Example 4 was measured to converge to a value of about 0%.

[0193] As shown from these results, the brightness of the display device DD1 according to the embodiment of the present disclosure is relatively improved by including the second light blocking pattern LBP2 spaced apart from the third light emitting layer EML in a plan view.

[0194] In addition, the in-plane separation distance DPO in the display devices of Examples 3 and 4 may be greater than the in-plane separation distance DPO in the display devices of Examples 1 and 2. Accordingly, when the viewing angle is about 0 degrees to about 15 degrees, the brightness of the display devices of Examples 3 and 4 is relatively more improved than the brightness of the display devices of Examples 1 and 2. In order to design the in-plane separation distance DPO to be relatively large, the second height H2 of the second light shielding pattern LBP2 may be designed to be relatively large.

[0195] Fig.17 It is along Figure 2 For example, Fig.17 is a cross-sectional view illustrating absorption of light by the first light-shielding pattern LBP1.

[0196] refer to Figure 2 and Fig.17 , in the first display area DA1, the first light emitting element LD1 of the first pixel PX1 may emit light. For example, in the first display area DA1, each of the 1-1th light emitting element LD1-1 and the 1-2th light emitting element LD1-2 may emit light. In the first display area DA1, the second light emitting element LD2 of the second pixel PX2 may also emit light. Hereinafter, the first light emitting element LD1 may be described in more detail, and redundant descriptions about the second light emitting element LD2 may not be repeated.

[0197] For example, the first display area DA1 may be located in a display area (eg, Figure 1 When the display device DD1 is applied to an automobile display device, the driver's seat may be located in the front direction of the first display area DA1 (eg, in or on it).

[0198] The first light emitting element LD1 may emit a first upper light PX1-LT propagating in an upward direction, a first front light PX1-LF propagating in a front direction, and a first lower light PX1-LB propagating in a downward direction. For example, each of the 1-1th light emitting element LD1-1 and the 1-2th light emitting element LD1-2 may emit a first upper light PX1-LT, a first front light PX1-LF, and a first lower light PX1-LB.

[0199] Similarly, the second light emitting element LD2 may emit second upper light propagating in an upward direction, second front light propagating in a front direction, and second lower light propagating in a downward direction.

[0200] The first light-shielding pattern LBP1 may absorb some of the light emitted from the first light-emitting element LD1 and the second light-emitting element LD2. In more detail, the first light-shielding pattern LBP1 may absorb the first upper light PX1-LT propagating in the upward direction at an angle greater than the second angle AGL2. In other words, when the angle between an imaginary straight line extending perpendicular or substantially perpendicular to the first light-emitting element LD1 and the direction in which the first upper light PX1-LT emitted from the first light-emitting element LD1 propagates is greater than the second angle AGL2, the first upper light PX1-LT may be absorbed by the first light-shielding pattern LBP1. Accordingly, the first light-shielding pattern LBP1 may adjust the viewing angle in the upward direction. For example, the second angle AGL2 may be approximately 30 degrees.

[0201] In addition, the first light-shielding pattern LBP1 can absorb the first lower light PX1-LB propagating at an angle greater than the second angle AGL2 in the downward direction. In other words, when the angle between an imaginary straight line extending perpendicular or substantially perpendicular to the first light-emitting element LD1 and the direction in which the first lower light PX1-LB emitted from the first light-emitting element LD1 propagates is greater than the second angle AGL2, the first lower light PX1-LB can be absorbed by the first light-shielding pattern LBP1. Accordingly, the first light-shielding pattern LBP1 can adjust the viewing angle in the downward direction.

[0202] In other words, the first light shielding pattern LBP1 can adjust the viewing angle in the up-down direction. In more detail, when the display device DD1 is driven in the second mode (e.g., narrow viewing angle mode), the first light shielding pattern LBP1 can adjust the viewing angle in the up-down direction, and when the display device DD1 is driven in the first mode (e.g., wide viewing angle mode), the first light shielding pattern LBP1 can adjust the viewing angle in the up-down direction. As a result, the problem of the image displayed in the first display area DA1 being reflected on the front windshield of the car, which may interfere with the driver's operation, can be suppressed.

[0203] For example, the first pixel PX1 and the second pixel PX2 disposed in the first display area DA1 may be driven independently of the first pixel PX1 and the second pixel PX2 disposed in the second display area DA2. In other words, even if the display device DD1 is driven in the second mode (e.g., the narrow viewing angle mode), in the first display area DA1, each of the first light emitting element LD1 of the first pixel PX1 and the second light emitting element LD2 of the second pixel PX2 may emit light. However, the present disclosure is not limited thereto.

[0204] As another example, a first pixel PX1 disposed in the first display area DA1 may be driven together with a first pixel PX1 disposed in the second display area DA2, and a second pixel PX2 disposed in the first display area DA1 may be driven together with a second pixel PX2 disposed in the second display area DA2. In other words, when the display device DD1 is driven in the second mode, in the first display area DA1, the first light emitting element LD1 of the first pixel PX1 may emit light, and in the first display area DA1, the second light emitting element LD2 of the second pixel PX2 may not emit light.

[0205] Fig.18 is a plan view illustrating a display device according to another embodiment of the present disclosure. Fig.19 yes Fig.18 An enlarged floor plan of area 'D'. Fig. 20 It is along Fig.19 A cross-sectional view taken along line IV-IV'.

[0206] refer to Fig.18 and Fig.19 , a display device DD2 according to another embodiment of the present disclosure may include a substrate SUB, a group pixel GPX, a first light-shielding pattern LBP1, a second light-shielding pattern LBP2, and a third light-shielding pattern LBP3.

[0207] The display device DD2 may be similar to the above-referenced display device except that the display device DD2 may further include a third light blocking pattern LBP3 in the first display area DA1. Figures 1 to 17 The display device DD1 described above is the same or substantially the same. Figures 1 to 17 Redundant description of components that are identical or substantially identical to components of the described display device DD1.

[0208] The group pixels GPX may be repeatedly arranged on the substrate SUB in the first display area DA1 along the first direction DR1 and the second direction DR2. Each of the group pixels GPX may include a first pixel PX1 and a second pixel PX2. For example, the first pixel PX1 may correspond to a left pixel of the group pixel GPX, and the second pixel PX2 may correspond to a right pixel of the group pixel GPX.

[0209] The third light blocking patterns LBP3 may be repeatedly disposed on the substrate SUB in the first display area DA1 along the first direction DR1. The third light blocking patterns LBP3 may be spaced apart from each other in the first direction DR1 in the first display area DA1. Each of the third light blocking patterns LBP3 may extend in the second direction DR2.

[0210] In an embodiment, each of the third light-shielding patterns LBP3 may be disposed adjacent to the corresponding second pixel PX2. In more detail, some of the third light-shielding patterns LBP3 may be adjacent to the first emission area EA1-PX2 of the second pixel PX2 and the second emission area EA2-PX2 of the second pixel PX2 in the first direction DR1. In addition, other portions of the third light-shielding pattern LBP3 may be adjacent to the third emission area EA3-PX2 of the second pixel PX2 in the first direction DR1.

[0211] The third light blocking pattern LBP3 may adjust the viewing angle in the first direction DR1 (eg, the left-right direction). In more detail, the third light blocking pattern LBP3 may adjust the viewing angle in the left direction or the right direction.

[0212] Further references Fig. 20According to another embodiment of the present disclosure, a display device DD2 may include a substrate SUB, a buffer layer BUF, a first thin film transistor TR1, a third thin film transistor TR3, a fourth thin film transistor TR4, a gate insulating layer GI, an interlayer insulating layer ILD, a through-hole insulating layer VIA, a 1-1th light emitting element LD1-1, a 1-3th light emitting element LD1-3, a 2-1th light emitting element LD2-1, a pixel defining layer PDL, an encapsulation layer TFE, and a light control layer LCL in a first display area DA1.

[0213] The light control layer LCL may be disposed on the encapsulation layer TFE. The light control layer LCL may include a third light shielding pattern LBP3 and a transmissive pattern TRP. The transmissive pattern TRP may surround the third light shielding pattern LBP3 (e.g., around its periphery). Light emitted from the 1-1th light emitting element LD1-1, the 1-3th light emitting element LD1-3, and the 2-1st light emitting element LD2-1 may pass through the transmissive pattern TRP. The third light shielding patterns LBP3 may be repeatedly disposed along the first direction DR1 and may be spaced apart from each other by a suitable distance (e.g., a predetermined distance).

[0214] In an embodiment, the third light shielding pattern LBP3 may be disposed in the same layer as the first light shielding pattern LBP1 and the second light shielding pattern LBP2. In other words, the first light shielding pattern LBP1, the second light shielding pattern LBP2, and the third light shielding pattern LBP3 may include the same material as each other and may be formed by the same process. Accordingly, the process efficiency for manufacturing the display device DD2 may be improved.

[0215] In an embodiment, the third height H3 of the third light-shielding pattern LBP3 may be equal to or substantially equal to the first height (eg, Figure 3 The first height H1 of the second light shielding pattern LBP2 and the second height H2 of the second light shielding pattern LBP2 (eg, Figure 5 The third height H3 may refer to a straight line distance from the upper surface of the encapsulation layer TFE to the upper surface of the third light shielding pattern LBP3 in the third direction DR3. For example, the third height H3 of the third light shielding pattern LBP3 may be about 40 micrometers to about 48 micrometers.

[0216] In an embodiment, each of the third light-shielding patterns LBP3 includes an organic material including a light-shielding material having a black color. Accordingly, the third light-shielding pattern LBP3 may selectively block some of the light emitted from the second pixel PX2. For example, the third light-shielding pattern LBP3 may selectively block some of the light emitted from the 2-1st light-emitting element LD2-1. In other words, the third light-shielding pattern LBP3 may adjust the viewing angle of the display device DD2 by selectively absorbing some of the light emitted from the 2-1st light-emitting element LD2-1. The third light-shielding pattern LBP3 may adjust the viewing angle in a first direction DR1 (e.g., a left-right direction). In more detail, the third light-shielding pattern LBP3 may adjust the viewing angle in a left direction or a right direction. Hereinafter, as a representative example, the case where the third light-shielding pattern LBP3 adjusts the viewing angle in the right direction may be described in more detail.

[0217] The third light blocking pattern LBP3 may not block light emitted from the first pixel PX1 and traveling in the right direction. For example, the third light blocking pattern LBP3 may not block light emitted from the 1-1th light emitting element LD1-1 and the 1-3th light emitting element LD1-3 and traveling in the right direction.

[0218] In an embodiment, the third light-shielding pattern LBP3 may be spaced apart from the first light-emitting element LD1 and the second light-emitting element LD2 in a plan view. In addition, the third light-shielding pattern LBP3 may overlap with the pixel defining layer PDL in a plan view. For example, the third light-shielding pattern LBP3 may be spaced apart from the 1-1 light-emitting element LD1-1, the 1-3 light-emitting element LD1-3, and the 2-1 light-emitting element LD2-1 in a plan view. Accordingly, when compared with a case where the third light-shielding pattern LBP3 overlaps with the first light-emitting element LD1 and the second light-emitting element LD2 in a plan view, the brightness of the display device DD2 may be relatively improved.

[0219] For example, the third width W3 of the third light-shielding pattern LBP3 may be greater than the first width (eg, Figure 3 The third width W3 may refer to a length of the third light shielding pattern LBP3 in the first direction DR1, and the first width may refer to a length of the first light shielding pattern LBP1 in the second direction DR2. However, the present disclosure is not limited thereto.

[0220] The third width W3 of the third light-shielding pattern LBP3 may be equal to or substantially equal to the second width (eg, Figure 5 The second width W2 may refer to a length of the second light blocking pattern LBP2 in the first direction DR1. However, the present disclosure is not limited thereto.

[0221] Figure 21 to Figure 23It is along Fig.19 For example, Fig.21 and Fig. 22 is a cross-sectional view illustrating a display device DD2 driven in a first mode, and Fig.23 2 is a cross-sectional view illustrating the display device DD2 driven in the second mode. The first mode may be defined as a mode for achieving a wide viewing angle, and the second mode may be defined as a mode for achieving a narrow viewing angle.

[0222] refer to Fig.19 and Fig.21 In the embodiment, when the display device DD2 is driven in the first mode, in the first display area DA1, each of the first light emitting element LD1 of the first pixel PX1 and the second light emitting element LD2 of the second pixel PX2 may emit light. For example, when the display device DD2 is driven in the first mode, in the first display area DA1, each of the 1-1 light emitting element LD1-1, the 1-3 light emitting element LD1-3, and the 2-1 light emitting element LD2-1 may emit light.

[0223] For example, the first display area DA1 may be located in a display area (eg, Fig.18 When the display device DD2 is applied to an automobile display device, the driver's seat may be located in the front direction of the first display area DA1 (e.g., in or on it), and the passenger seat may be located in the right direction of the first display area DA1 (e.g., in or on it).

[0224] The first light emitting element LD1 may emit a first right light PX1-LR propagating in the right direction and a first front light PX1-LF propagating in the front direction. For example, each of the 1-1 light emitting element LD1-1 and the 1-3 light emitting element LD1-3 may emit the first right light PX1-LR and the first front light PX1-LF. The first light emitting element LD1 may further emit a first left light propagating in the left direction (for example, Fig. 9 The first left light PX1-LL), but its redundant description may not be repeated.

[0225] Similarly, the second light emitting element LD2 may emit a second right light PX2-LR propagating in the right direction and a second front light PX2-LF propagating in the front direction. For example, the 2-1st light emitting element LD2-1 may emit a second right light PX2-LR and a second front light PX2-LF. The second light emitting element LD2 may further emit a second left light propagating in the left direction (for example, Fig. 9 The second left light PX2-LL), but its redundant description may not be repeated.

[0226] The third light-shielding pattern LBP3 may absorb a portion of the light emitted from the second light-emitting element LD2. In more detail, the third light-shielding pattern LBP3 may absorb the second right light PX2-LR propagating in the right direction at an angle greater than the third angle AGL3. In other words, when the angle between an imaginary straight line extending perpendicular or substantially perpendicular to the second light-emitting element LD2 and the direction in which the second right light PX2-LR emitted from the second light-emitting element LD2 propagates is greater than the third angle AGL3, the second right light PX2-LR may be absorbed by the third light-shielding pattern LBP3. In an embodiment, the third angle AGL3 may be equal to or substantially equal to the first angle (e.g., Fig. 9 The first angle AGL1 of the embodiment of the present invention may be approximately 45 degrees. However, the present disclosure is not limited thereto. For example, the third angle AGL3 may be approximately 45 degrees.

[0227] On the other hand, the third light blocking pattern LBP3 may not absorb the first right light PX1 -LR emitted from the first light emitting element LD1 .

[0228] When the display device DD2 is driven in the first mode (e.g., wide viewing angle mode), a passenger located in the right direction of the first display area DA1 (e.g., in or on it) can view the first right light PX1-LR. Accordingly, the passenger can view the image displayed in the first display area DA1. In addition, a driver located in the front direction of the first display area DA1 (e.g., in or on it) can view the first front light PX1-LF and the second front light PX2-LF. Accordingly, the driver can view the image displayed in the first display area DA1.

[0229] refer to Fig.19 and Fig. 22 In another embodiment, when the display device DD2 is driven in the first mode, in the first display area DA1, the first light emitting element LD1 of the first pixel PX1 may emit light, and in the first display area DA1, the second light emitting element LD2 of the second pixel PX2 may not emit light. For example, when the display device DD2 is driven in the first mode, in the first display area DA1, each of the 1-1th light emitting element LD1-1 and the 1-3th light emitting element LD1-3 may emit light, and in the first display area DA1, the 2-1th light emitting element LD2-1 may not emit light.

[0230] The first light emitting element LD1 may emit first right light PX1 -LR traveling in the right direction and first front light PX1 -LF traveling in the front direction.

[0231] When the display device DD2 is driven in the first mode (e.g., wide viewing angle mode), a passenger located in the right direction of the first display area DA1 (e.g., in or on it) can view the first right light PX1-LR. Accordingly, the passenger can view the image displayed in the first display area DA1. In addition, a driver located in the front direction of the first display area DA1 (e.g., in or on it) can view the first front light PX1-LF. Accordingly, the driver can view the image displayed in the first display area DA1.

[0232] refer to Fig.19 and Fig.23 , when the display device DD2 is driven in the second mode (e.g., the narrow viewing angle mode), in the first display area DA1, the first light emitting element LD1 of the first pixel PX1 may not emit light, and in the first display area DA1, the second light emitting element LD2 of the second pixel PX2 may emit light. For example, when the display device DD2 is driven in the second mode, in the first display area DA1, each of the 1-1th light emitting element LD1-1 and the 1-3th light emitting element LD1-3 may not emit light, and in the first display area DA1, the 2-1th light emitting element LD2-1 may emit light.

[0233] The second light emitting element LD2 may emit second right light PX2 -LR traveling in the right direction and second front light PX2 -LF traveling in the front direction.

[0234] The third light-shielding pattern LBP3 may absorb a portion of the light emitted from the second light-emitting element LD2. In more detail, the third light-shielding pattern LBP3 may absorb the second right light PX2-LR propagating in the right direction at an angle greater than the third angle AGL3. In other words, when the angle between an imaginary straight line extending perpendicular or substantially perpendicular to the second light-emitting element LD2 and the direction in which the second right light PX2-LR emitted from the second light-emitting element LD2 propagates is greater than the third angle AGL3, the second right light PX2-LR may be absorbed by the third light-shielding pattern LBP3. Accordingly, the third light-shielding pattern LBP3 may adjust the viewing angle in the right direction. For example, the third angle AGL3 may be approximately 45 degrees.

[0235] When the display device DD2 is driven in the second mode (e.g., narrow viewing angle mode), a passenger located in the right direction of the first display area DA1 (e.g., in or on it) cannot view the second right light PX2-LR propagating at an angle greater than the third angle AGL3. Accordingly, the passenger cannot view the image displayed in the first display area DA1. On the other hand, a driver located in the front direction of the first display area DA1 (e.g., in or on it) can view the second front light PX2-LF. Accordingly, the driver can view the image displayed in the first display area DA1.

[0236] Fig.24 is a plan view illustrating a display device according to another embodiment of the present disclosure. Fig.25 yes Fig.24 An enlarged plan view of area 'E'. Fig.26 It is along Fig.25 A cross-sectional view taken along line V-V'.

[0237] refer to Fig.24 and Fig.25 , a display device DD3 according to another embodiment of the present disclosure may include a substrate SUB, a group pixel GPX, a first light-shielding pattern LBP1, a second light-shielding pattern LBP2, a third light-shielding pattern LBP3, and a fourth light-shielding pattern LBP4.

[0238] The display device DD3 may be similar to the above reference numerals except that the display device DD3 may further include a fourth light blocking pattern LBP4 in the second display area DA2. Figures 18 to 23 The display device DD2 described above is the same or substantially the same. Figures 18 to 23 Redundant description of components that are identical or substantially identical to components of the described display device DD2.

[0239] The group pixels GPX may be repeatedly arranged on the substrate SUB in the second display area DA2 along the first direction DR1 and the second direction DR2. Each of the group pixels GPX may include a first pixel PX1 and a second pixel PX2. For example, the first pixel PX1 may correspond to a left pixel of the group pixel GPX, and the second pixel PX2 may correspond to a right pixel of the group pixel GPX.

[0240] The fourth light blocking patterns LBP4 may be repeatedly disposed on the substrate SUB in the second display area DA2 along the second direction DR2. The fourth light blocking patterns LBP4 may be spaced apart from each other in the second direction DR2 in the second display area DA2. Each of the fourth light blocking patterns LBP4 may extend in the first direction DR1.

[0241] Further references Fig.26 According to another embodiment of the present disclosure, a display device DD3 may include a substrate SUB, a buffer layer BUF, a first thin film transistor TR1, a second thin film transistor TR2, a gate insulating layer GI, an interlayer insulating layer ILD, a through-hole insulating layer VIA, a 1-1th light emitting element LD1-1, a 1-2th light emitting element LD1-2, a pixel defining layer PDL, an encapsulation layer TFE and a light control layer LCL in a second display area DA2.

[0242] The light control layer LCL may be disposed on the encapsulation layer TFE. The light control layer LCL may include a fourth light shielding pattern LBP4 and a transmissive pattern TRP. The transmissive pattern TRP may surround the fourth light shielding pattern LBP4 (e.g., around its periphery). Light emitted from the 1-1st light emitting element LD1-1 and the 1-2nd light emitting element LD1-2 may pass through the transmissive pattern TRP. The fourth light shielding patterns LBP4 may be repeatedly disposed along the second direction DR2 and may be spaced apart from each other by a suitable distance (e.g., a predetermined distance).

[0243] In an embodiment, the fourth light shielding pattern LBP4 may be disposed in the same layer as the first light shielding pattern LBP1, the second light shielding pattern LBP2, and the third light shielding pattern LBP3. In other words, the first light shielding pattern LBP1, the second light shielding pattern LBP2, the third light shielding pattern LBP3, and the fourth light shielding pattern LBP4 may include the same material as each other and may be formed by the same process. Accordingly, the process efficiency for manufacturing the display device DD3 may be improved.

[0244] In an embodiment, the fourth height H4 of the fourth light-shielding pattern LBP4 may be equal to or substantially equal to the first height (eg, Figure 3 ), a first height H1 of the second light shielding pattern LBP2 (eg, Figure 5 The second height H2 of the third light shielding pattern LBP3 and the third height H3 of the third light shielding pattern LBP3 (eg, Fig. 20 For example, the fourth height H4 of the fourth light blocking pattern LBP4 may be about 40 micrometers to about 48 micrometers.

[0245] In an embodiment, Fig.25 As shown in FIG. 1 , some of the fourth light shielding pattern LBP4 may partially overlap with the first light emitting element LD1 and the second light emitting element LD2 in a plan view. In other words, some of the fourth light shielding pattern LBP4 may partially overlap with the first light emitting element LD1 and the second light emitting element LD2 in a plan view, and other portions of the fourth light shielding pattern LBP4 may not overlap with the first light emitting element LD1 and the second light emitting element LD2 in a plan view. For example, Fig.26 As illustrated in FIG. 1 , some of the fourth light-shielding patterns LBP4 may partially overlap the 1-1th light-emitting element LD1-1 and the 1-2th light-emitting element LD1-2 in a plan view. However, the present disclosure is not limited thereto, and all of the fourth light-shielding patterns LBP4 may partially overlap the first light-emitting element LD1 and the second light-emitting element LD2 in a plan view.

[0246] In an embodiment, each of the fourth light shielding patterns LBP4 may include an organic material including a light shielding material having a black color. Accordingly, the fourth light shielding pattern LBP4 may selectively block some of the light emitted from the first pixel PX1 and the second pixel PX2. For example, the fourth light shielding pattern LBP4 may selectively block some of the light emitted from the 1-1th light emitting element LD1-1 and the 1-2th light emitting element LD1-2. In other words, the fourth light shielding pattern LBP4 may adjust the viewing angle of the display device DD3 by selectively absorbing some of the light emitted from the 1-1th light emitting element LD1-1 and the 1-2th light emitting element LD1-2. In more detail, the fourth light shielding pattern LBP4 may adjust the viewing angle in the second direction DR2 (e.g., the up and down direction).

[0247] For example, the fourth width W4 of the fourth light-shielding pattern LBP4 may be smaller than the second width (eg, Figure 5 The second width W2 of the third light shielding pattern LBP3 and the third width W3 of the third light shielding pattern LBP3 (for example, Fig. 20 Here, the fourth width W4 may refer to the length of the fourth light shielding pattern LBP4 in the second direction DR2. The second width may refer to the length of the second light shielding pattern LBP2 in the first direction DR1. The third width may refer to the length of the third light shielding pattern LBP3 in the first direction DR1. However, the present disclosure is not limited thereto.

[0248] In addition, the fourth width W4 of the fourth light-shielding pattern LBP4 may be equal to or substantially equal to the first width (eg, Figure 3 Here, the first width may refer to a length of the first light blocking pattern LBP1 in the second direction DR2. However, the present disclosure is not limited thereto.

[0249] Fig. 27 It is along Fig.25 For example, Fig. 27 is a cross-sectional view illustrating absorption of light by the fourth light blocking pattern LBP4.

[0250] refer to Fig.25 and Fig. 27 , in the second display area DA2, the first light emitting element LD1 of the first pixel PX1 may emit light. For example, in the second display area DA2, each of the 1-1th light emitting element LD1-1 and the 1-2th light emitting element LD1-2 may emit light. In the second display area DA2, the second light emitting element LD2 of the second pixel PX2 may also emit light. Hereinafter, the first light emitting element LD1 may be described in more detail, and redundant descriptions about the second light emitting element LD2 may not be repeated.

[0251] For example, the second display area DA2 may be located in the display area (eg, Fig.24 When the display device DD3 is applied to a car display device, the passenger seat may be located in the front direction of the second display area DA2 (eg, in or on it).

[0252] The first light emitting element LD1 may emit a first upper light PX1-LT propagating in an upward direction, a first front light PX1-LF propagating in a front direction, and a first lower light PX1-LB propagating in a downward direction. For example, each of the 1-1th light emitting element LD1-1 and the 1-2th light emitting element LD1-2 may emit a first upper light PX1-LT, a first front light PX1-LF, and a first lower light PX1-LB.

[0253] Similarly, the second light emitting element LD2 may emit second upper light propagating in an upward direction, second front light propagating in a front direction, and second lower light propagating in a downward direction.

[0254] The fourth light shading pattern LBP4 can absorb some of the light emitted from the first light emitting element LD1 and the second light emitting element LD2. In more detail, the fourth light shading pattern LBP4 can absorb the first upper light PX1-LT propagating in the upward direction at an angle greater than the fourth angle AGL4. In other words, when the angle between an imaginary straight line extending perpendicular or substantially perpendicular to the first light emitting element LD1 and the direction in which the first upper light PX1-LT emitted from the first light emitting element LD1 propagates is greater than the fourth angle AGL4, the first upper light PX1-LT can be absorbed by the fourth light shading pattern LBP4. Accordingly, the fourth light shading pattern LBP4 can adjust the viewing angle in the upward direction. In an embodiment, the fourth angle AGL4 may be equal to or substantially equal to the second angle (for example, Fig.17 The fourth angle AGL4 may be about 30 degrees.

[0255] In addition, the fourth light-shielding pattern LBP4 can absorb the first lower light PX1-LB propagating in the downward direction at an angle greater than the fourth angle AGL4. In other words, when the angle between the imaginary straight line extending perpendicularly or substantially perpendicularly to the first light-emitting element LD1 and the direction in which the first lower light PX1-LB emitted from the first light-emitting element LD1 propagates is greater than the fourth angle AGL4, the first lower light PX1-LB can be absorbed by the fourth light-shielding pattern LBP4. Accordingly, the fourth light-shielding pattern LBP4 can adjust the viewing angle in the downward direction.

[0256] In other words, the fourth light shielding pattern LBP4 can adjust the viewing angle in the up-down direction. In more detail, when the display device DD3 is driven in the second mode (e.g., narrow viewing angle mode), the fourth light shielding pattern LBP4 can adjust the viewing angle in the up-down direction, and when the display device DD3 is driven in the first mode (e.g., wide viewing angle mode), the fourth light shielding pattern LBP4 can adjust the viewing angle in the up-down direction. As a result, the problem of the image displayed in the second display area DA2 being reflected on the front windshield of the car, which may interfere with the driver's operation, can be suppressed.

[0257] Fig.28 is a plan view illustrating a display device according to another embodiment of the present disclosure.

[0258] refer to Fig.28 A display device DD4 according to another embodiment of the present disclosure may include a substrate SUB, a group pixel GPX, a first light shielding pattern LBP1, a second light shielding pattern LBP2, a third light shielding pattern LBP3, a fourth light shielding pattern LBP4, a fifth light shielding pattern LBP5, and a sixth light shielding pattern LBP6.

[0259] The display device DD4 may be similar to the above-referenced display device except that the display device DD4 may further include a fifth light shielding pattern LBP5 and a sixth light shielding pattern LBP6 in the third display area DA3. Figure 22 to Figure 25 The display device DD3 described above is the same or substantially the same. Figure 22 to Figure 25 Redundant description of components that are identical or substantially identical to components of the described display device DD3.

[0260] The group pixels GPX may be repeatedly arranged on the substrate SUB in the third display area DA3 along the first direction DR1 and the second direction DR2. Each of the group pixels GPX may include a first pixel PX1 and a second pixel PX2. For example, the first pixel PX1 may correspond to a left pixel of the group pixel GPX, and the second pixel PX2 may correspond to a right pixel of the group pixel GPX.

[0261] The fifth light-shielding pattern LBP5 may be repeatedly disposed on the substrate SUB in the third display area DA3 along the second direction DR2. The fifth light-shielding patterns LBP5 may be spaced apart from each other in the second direction DR2 in the third display area DA3. Each of the fifth light-shielding patterns LBP5 may extend in the first direction DR1. In an embodiment, the fifth light-shielding pattern LBP5 may be connected to the first light-shielding pattern LBP1 and the fourth light-shielding pattern LBP4. In other words, the first light-shielding pattern LBP1, the fourth light-shielding pattern LBP4, and the fifth light-shielding pattern LBP5 may be connected to each other and extend continuously.

[0262] In an embodiment, each of the fifth light shielding patterns LBP5 may include an organic material including a light shielding material having a black color. The fifth light shielding pattern LBP5 may adjust a viewing angle in the second direction DR2 (eg, an up-and-down direction). For example, the fifth light shielding pattern LBP5 may be similar to Fig.17 The first light shielding pattern LBP1 and Fig. 27 As a result, it is possible to suppress the problem that the image displayed in the third display area DA3 is reflected on the front windshield of the car, which may interfere with the driver's operation.

[0263] The sixth light blocking patterns LBP6 may be repeatedly disposed on the substrate SUB in the third display area DA3 along the first direction DR1. The sixth light blocking patterns LBP6 may be spaced apart from each other in the first direction DR1 in the third display area DA3. Each of the sixth light blocking patterns LBP6 may extend in the second direction DR2.

[0264] In an embodiment, each of the sixth light shielding patterns LBP6 includes an organic material including a light shielding material having a black color. The sixth light shielding pattern LBP6 may adjust a viewing angle in a first direction DR1 (eg, a left-right direction). For example, the sixth light shielding pattern LBP6 may be similar to Fig.11 The viewing angle is adjusted in the left direction as shown in the second light shielding pattern LBP2 shown in FIG. In this case, the driver cannot view the image displayed in the third display area DA3. On the other hand, the passenger can view the image displayed in the third display area DA3.

[0265] As another example, the sixth light blocking pattern LBP6 may be similar to Fig.23 The viewing angle is adjusted in the right direction as in the third light shielding pattern LBP3 shown in FIG. In this case, the driver can view the image displayed in the third display area DA3. On the other hand, the passenger cannot view the image displayed in the third display area DA3.

[0266] In an embodiment, the first light shielding pattern LBP1, the second light shielding pattern LBP2, the third light shielding pattern LBP3, the fourth light shielding pattern LBP4, the fifth light shielding pattern LBP5 and the sixth light shielding pattern LBP6 may be arranged in the same layer as each other.
