Description

BACKGROUND Area The present disclosure relates to a display device and in particular a display device capable of displaying two different images on a display panel. Description of the related technology As technology advances in modern society, display devices are widely used to provide information to users. A display device can be found not only in an electronic board, which simply transmits visual information in a one-way manner, but also in various electronic devices that require more advanced technology to recognize user input and provide information in response to that input. Representative examples of display devices include a liquid crystal display (LCD), a field emission display (FED), an electrowetting display (EWD), and an organic light-emitting display (OLED). Among these, the organic light-emitting display (OLED) is a self-emitting type of display and, unlike the liquid crystal display (LCD), does not require a separate light source, thus enabling lightweight and thin manufacturing. Furthermore, the OLED is advantageous in terms of power consumption due to its low-voltage drive and also exhibits excellent performance in color reproduction, response time, viewing angle, and contrast ratio (CR), so it is expected to be used in various fields. Multi-view display technologies, capable of presenting different visual information to different viewers from a single screen, are increasingly in demand. However, many challenges exist, such as effectively isolating the light paths for each view without introducing significant drawbacks and complexity. For example, previous approaches often resulted in viewing zones with reduced brightness, crosstalk issues, and narrower viewing angles, and / or required complex and costly manufacturing processes. Therefore, there is a need for a display configuration that can deliver independent, high-quality images to multiple viewers while maintaining display brightness and simplifying manufacturing. OVERVIEW OF THE REVELATION One objective to be achieved by the present disclosure is to provide a display device with an improved function that makes it possible to view two different images depending on the viewing angle using a display panel. Another objective to be achieved by the present disclosure is to provide a process-optimized display device capable of forming a barrier that limits a light path without adding a separate wiring layer, thereby reducing the manufacturing energy required to form the barrier.

Various embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. Fig. 1 is an exemplary diagram of a display device according to an exemplary embodiment of the present disclosure. The display device 100 can be arranged on at least one section of a vehicle's dashboard. The vehicle's dashboard can, for example, have a configuration located in front of the vehicle's front seats, such as a driver's seat and a passenger's seat. For example, the vehicle's dashboard can be configured with an input setup for operating various functions within the vehicle, such as an air conditioning system, an audio system, and a navigation system. In one exemplary embodiment of the present disclosure, the display device 100 is arranged on the dashboard of the vehicle and can be operated as an input unit for controlling at least some of the various functions of the vehicle. The display device 100 can provide various information relating to the vehicle, for example, vehicle driving information such as speed, remaining fuel quantity, and distance traveled, and information relating to vehicle components such as tire damage or tire inflation level. However, embodiments are not limited to this, and the multi-view display device can be applied to other types of situations, particularly those involving common spaces such as work environments, gaming environments, advertisements, etc. In an exemplary embodiment of the present disclosure, the display device 100 can be arranged over the driver's seat and the front passenger seat, which are located in the front seats of the vehicle. A user of the display device 100 can include the driver of the vehicle and a passenger in the front passenger seat. Both the driver and the front passenger can use the display device 100. In an exemplary embodiment of the present disclosure, the display device 100 shown in Fig. 1 may be partially depicted. The display device 100 shown in Fig. 1 may, of various configurations contained within it, represent a display panel. In particular, for example, the display device 100 shown in Fig. 1 may represent at least a portion of an active area and a non-active area of ​​the display panel. Configurations other than the portion shown in Fig. 1 may, of the configurations of the display device 100, be mounted inside (or at least partially inside) the vehicle. Referring to Fig. 1, a driver of the vehicle and a passenger in the front passenger seat can view two different contents on a left and a right side using a display device 100. For example, using a display device 100, the driver can view content L on the left side, and the passenger in the front passenger seat can view content R on the right side, but this is not limited to this. Fig. 2 is a functional block diagram of a display device according to an exemplary embodiment of the present disclosure. The display device 100 according to an exemplary embodiment of the present disclosure can use an electroluminescent display device. The electroluminescent display device can comprise an organic light-emitting diode (OLED) display device, a quantum dot light-emitting diode (QLED) display device, or an inorganic light-emitting diode display device. Referring to Fig. 2, the display device 100 according to an exemplary embodiment of the present disclosure can comprise a display panel PN, a data control circuit DD, a gate control circuit GD and a timing control T-con. In one exemplary embodiment, the display panel PN can generate an image to be provided to a user. For example, the display panel PN can generate and display an image to be provided to the user by a plurality of pixels PX, each of which is arranged with a pixel circuit. The data control circuit DD, the gate control circuit GD, and the timing control T-con can provide signals for controlling each pixel PX via signal lines. These signal lines can, for example, include data lines DL and gate lines GL. In some situations, the display device may also include a power supply unit. In this situation, signals for controlling the pixels PX can be provided via power supply lines connecting the power supply unit and the display panel PN. Depending on an exemplary embodiment, the power supply unit can supply current to the data drive circuit DD and the gate drive circuit GD. The data drive circuit DD and the gate drive circuit GD can be controlled based on the current supplied by the power supply unit. For example, the data control circuit DD can apply a data signal to each pixel PX via the data lines DL, the gate control circuit GD can apply a gate signal to each pixel PX via the gate lines GL, and the power supply unit can supply a voltage to each pixel PX via power supply lines. The T-con timing controller can control the DD data input circuit and the GD gate input circuit. For example, the T-con timing controller can rearrange externally input digital video data according to the resolution of the PN display panel and feed it to the DD data input circuit. The DD data control circuit can convert digital video data input by the T-con timing controller into an analog data voltage based on a data control signal and supply the analog data voltage to a plurality of data lines. The gate drive circuit (GD) can generate a sampling signal and an emission signal (or an emission control signal) based on a gate control signal. The gate drive circuit (GD) can include a sampling driver and a light emission signal driver. The sampling driver can generate a sampling signal in a line-sequential manner to drive at least one sampling line connected to a respective pixel row and can supply the sampling signal to the sampling lines. The light emission signal driver can generate a light emission signal in a line-sequential manner to drive at least one light emission signal line connected to a respective pixel row and can supply the light emission signal to the light emission signal lines. In one exemplary embodiment, the gate driver circuit GD can be arranged in the display panel PN using a gate driver-in-panel (GIP) method. For example, the gate driver circuit GD can be divided into a plurality of sections and arranged on at least two side faces of the display panel PN. The PN display panel can have an active area and a non-active area. The active area can contain a plurality of pixels PX. In each pixel PX, a plurality of data lines and a plurality of gate lines can intersect, and subpixels can be arranged at each of the intersection points. Each subpixel contained in a pixel PX can emit light of a different color. For example, the pixel PX can implement blue, red, and green using three subpixels. However, the present disclosure is not limited to this, and in some situations, the pixel PX can further include an additional subpixel for implementing a specific color, such as white. An area that implements blue in the pixel PX can be called a blue subpixel, an area that implements red can be called a red subpixel, and an area that implements green can be called a green subpixel. The inactive region can be arranged along the perimeter of the active region. Various components for driving a pixel circuit located within the pixel PX can be located in the inactive region. For example, at least a portion of the gate driver circuit GD can be located in the inactive region. The inactive region can be referred to as a boundary region. Fig. 3A is an enlarged top view of a pixel of a display device according to an exemplary embodiment of the present disclosure. Fig. 3B is an enlarged top view of a first subpixel of a display device according to an exemplary embodiment of the present disclosure. Fig. 3C is an enlarged top view of a second subpixel of a display device according to an exemplary embodiment of the present disclosure. Fig. 4 is a cross-sectional view along a line AA' of Fig. 3A. Fig. 5 is a cross-sectional view along a line BB' of Fig. 3A. Fig. 4 represents a cross-section of a plurality of first subpixels SP1 emitting the same color in a pixel PX, and Fig. 5 represents a cross-section of a plurality of second subpixels SP2 emitting the same color in a pixel PX. In Fig. 4 and Fig. 5, the subpixels are shown in the diagram.Figure 5 simplifies the explanation of a plurality of subpixels RSP, GSP and BSP, showing only the first subpixel SP1 and the second subpixel SP2 of a red subpixel RSP; however, further subpixels GSP and BSP can be set up in such a way that they have the same cross-section. First, with reference to Figures 3A to 3C, each of the plurality of pixels PX can have a plurality of subpixels RSP, GSP, and BSP representing different colors. For example, each pixel PX can have a blue subpixel BSP implementing blue, a red subpixel RSP implementing red, and a green subpixel GSP implementing green. A pixel circuit can be arranged in each of the plurality of subpixels RSP, GSP, and BSP. A pixel circuit corresponding to each of the subpixels RSP, GSP, and BSP can be arranged. The red subpixel RSP, green subpixel GSP, and blue subpixel BSP can be arranged in a triangular configuration, but embodiments are not limited to this. Each of the plurality of subpixels RSP, GSP, and BSP can have a first subpixel SP1 and a second subpixel SP2 that emit the same color. The first subpixel SP1 and the second subpixel SP2 can emit light in different directions. The first subpixel SP1 can emit light in a first direction (e.g., left), and the second subpixel SP2 can emit light in a second direction (e.g., right), opposite to the first direction (e.g., left). For example, the first subpixel SP1 can emit light in the left direction, and the second subpixel SP2 can emit light in the right direction, but this is not limited. For example, according to another embodiment, the first subpixel SP1 can emit light in an upward direction, and the second subpixel SP2 can emit light in a downward direction, and so on. Referring to Figs. 3A to 5, in each of the plurality of subpixels RSP, GSP and BSP, the first subpixel SP1 has a first region 161E in which a first transistor T1, a first light-emitting diode ED1 and a first light path changing part 161 are arranged, and the second subpixel SP2 has a second region 162E in which a second transistor T2, a second light-emitting diode ED2 and a second light path changing part 162 are arranged. In the first subpixel SP1 of each of the plurality of subpixels RSP, GSP, and BSP, a region in which the first light path modifying part 161 is located can be designated as a first region 161E. For example, the first region 161E can be a region in which light generated by the first light-emitting diode ED1 is amplified and emitted through the first light path modifying part 161. Accordingly, the size of the first region 161E can be larger than, but is not limited to, the size of the first light path modifying part 161. In the second subpixel SP2 of each of the plurality of subpixels RSP, GSP, and BSP, a region in which the second light path modifying element 162 is located can be designated as a second region 162E. For example, the second region 162E can be a region in which light generated by the second light-emitting diode ED2 is amplified and emitted through the second light path modifying element 162. Accordingly, the size of the second region 162E can be larger than the size of the second light path modifying element 162, but is not limited to this. The first region 161E and the second region 162E of each of the plurality of subpixels RSP, GSP, and BSP can have a shape corresponding to the first light path change part 161 and the second light path change part 162 located in the respective subpixels RSP, GSP, and BSP. For example, if the area shape of the first light path change part 161 and the second light path change part 162 of each of the plurality of subpixels RSP, GSP, and BSP is circular or rectangular, then the first region 161E and the second region 162E can have a circular or rectangular shape. In this context, a plurality of first subpixels SP1 and second subpixels SP2 can be arranged within each of the plurality of subpixels RSP, GSP, and BSP. For example, in the red subpixel RSP of a pixel PX, two first areas 161E and two second areas 162E can be arranged. However, the red subpixel RSP of a pixel PX can also contain only one first area 161E and one second area 162E, but this is not the limit. The first subpixel SP1 in each of the plurality of subpixels RSP, GSP, and BSP can be operated independently of the second subpixel SP2. For example, in each of the plurality of subpixels RSP, GSP, and BSP, the first light-emitting diode ED1, which is positioned in the first subpixel SP1 of the plurality of subpixels RSP, GSP, and BSP, and the second light-emitting diode ED2, which is positioned in the second subpixel SP2 of the plurality of subpixels RSP, GSP, and BSP, can be operated independently of each other. In the first subpixel SP1, a first light path modifying element 161 is arranged above the first light-emitting diode ED1 for modifying a light path of light emitted by the first light-emitting diode ED1. The first light path modifying element 161 is arranged such that it overlaps an emission region EA of the first light-emitting diode ED1. In the second subpixel SP2, a second light path modifying element 162 is arranged above the second light-emitting diode ED2 for modifying a light path of light emitted by the second light-emitting diode ED2. The second light path modifying element 162 is arranged such that it overlaps an emission region EA of the second light-emitting diode ED2. The emission region EA of the light-emitting diodes ED1 and ED2 can be a region in which light emitted by a light-emitting diode ED1 or ED2 is emitted through an opening region of a black matrix BM arranged over the light-emitting diodes ED1 and ED2, but is not limited to this. For example, the first light-path-modifying element 161 can be a first lens that modifies the path of light emitted by the first light-emitting diode ED1 to the left (e.g., first direction), and the second light-path-modifying element 162 can be a second lens that modifies the path of light emitted by the second light-emitting diode ED2 to the right (e.g., second direction). However, the present disclosure is not limited to this; any configuration can be used as long as it can modify a light path (e.g., upward, downward, or diagonal directions, etc.). The first light-path-modifying element 161 and the second light-path-modifying element 162 can be optical elements or optical lenses. Referring to Figures 3A to 5, in the first subpixel SP1 of each of the plurality of subpixels RSP, GSP, and BSP, the center of the first light path modification section 161 can be arranged at a predetermined distance in a left direction (e.g., a first direction) from the center of the first light-emitting diode ED1. In the second subpixel SP2 of each of the plurality of subpixels RSP, GSP, and BSP, the center of the second light path modification section 162 can be arranged at a predetermined distance in a right direction (e.g., a second direction) from the center of the second light-emitting diode ED2. The center of the first light path modification section 161 can be arranged at a predetermined distance in the left direction (the first direction) based on the emission region EA of the first light-emitting diode ED1.The center of the second light path modification section 162 can be positioned at a predetermined distance in the right direction (the second direction) based on the emission area EA of the second light-emitting diode ED2. For example, to direct light to a specific side, the lens in each subpixel can be intentionally offset from its light source. The lens can be shifted to the left of the light source to direct light to the left, and to the right to direct light to the right. In a pixel PX, the first light-emitting diode ED1 and the second light-emitting diode ED2 can be arranged for each of the first light path change part 161 and the second light path change part 162 of the plurality of subpixels RSP, GSP and BSP. For example, in a pixel PX there can be a first light-emitting diode ED1, which is located in the first light path change part 161 of a red subpixel RSP, a second light-emitting diode ED2, which is located in the second light path change part 162 of the red subpixel RSP, a first light-emitting diode ED1, which is located in the first light path change part 161 of a green subpixel GSP, a second light-emitting diode ED2, which is located in the second light path change part 162 of the green subpixel GSP, a first light-emitting diode ED1, which is located in the first light path change part 161 of a blue subpixel BSP, and a second light-emitting diode ED2, which is located in the second light path change part 162 of the blue subpixel BSP. Referring to Figures 4 and 5, a light path modifying element 161 or light path modifying element 162 can be arranged above a light-emitting diode ED1 or ED2. However, as shown in Figures 3A to 5, if light path modifying elements 161 and 162 are arranged side by side in a subpixel RSP, GSP, or BSP that emits the same color and modify a light path in the same direction, the light path modifying elements 161 and 162 can be arranged above the same light-emitting diode ED1 or ED2. For example, in a subpixel RSP, GSP, or BSP that emits the same color, if a plurality of first light path modifying elements 161 are arranged side by side, the plurality of first light path modifying elements 161 can be arranged above a first light-emitting diode ED1.In a subpixel RSP, GSP or BSP that emits the same color when a plurality of second light path modifying parts 162 are arranged next to each other, the plurality of second light path modifying parts 162 may be arranged above a second light-emitting diode ED2, but are not limited to this. Referring to Fig. 4 and Fig. 5, a display device 100 according to an exemplary embodiment of the present disclosure can comprise a substrate 110, a buffer layer 111, a gate insulating layer 112, an intermediate insulating layer 113, a lower protective layer 114, a coating layer 115, a first transistor T1, a second transistor T2, a first light-emitting diode ED1, a second light-emitting diode ED2, an encapsulation element 150, a touch buffer layer 117, a bridge electrode BE, a touch intermediate insulating layer 118, a black matrix BM, a touch insulating layer 119a, a first additional insulating layer 119b1, a second additional insulating layer 119b2, a first light path modifying element 161, a second light path modifying element 162, a touch electrode TE, a first have barrier part BR1, a second barrier part BR2 and an upper protective layer 170. The substrate 110 can be arranged in such a way that it supports other components arranged on the substrate 110. The substrate 110 can be made of an insulating material. The substrate 110 can be made of a transparent material. For example, the substrate 110 can be made of glass or plastic, but is not limited to these materials. The buffer layer 111 can be positioned between the substrate 110 and a driver section of each of the subpixels RSP, GSP, and BSP. The buffer layer can suppress contamination of the substrate 110 during the driver section formation process. For example, the upper surface of the substrate 110 facing the driver section of each of the subpixels RSP, GSP, and BSP can be covered by the buffer layer 111. The driver section of each of the subpixels RSP, GSP, and BSP can be positioned on top of the buffer layer 111. The buffer layer 111 can comprise an insulating material. For example, the buffer layer 111 can comprise an inorganic insulating material, such as silicon dioxide (SiOx) and silicon nitride (SiNx). The buffer layer 111 can have a multilayer structure. For example, the buffer layer 111 can have a laminated structure consisting of a layer made of silicon nitride (SiNx) and a layer made of silicon dioxide (SiOx), but is not limited to this. The gate-insulating layer 112 can be arranged on the buffer layer 111. The gate-insulating layer 112 can extend between a semiconductor layer and a gate electrode of a transistor. For example, the gate electrodes GE1 and GE2 of the first transistor T1 and the second transistor T2 can be isolated from the semiconductor layers ACT1 and ACT2 of the first transistor T1 and the second transistor T2 by the gate-insulating layer 112. The gate-insulating layer 112 can cover the first semiconductor layer ACT1 and the second semiconductor layer ACT2 of each of the subpixels RSP, GSP, and BSP. The gate electrodes GE1 and GE2 of the first transistor T1 and the second transistor T2 can be arranged on the gate-insulating layer 112. The gate insulating layer 112 can comprise an insulating material. For example, the gate insulating layer 112 can comprise an inorganic insulating material, such as silicon dioxide (SiO₂) and silicon nitride (SiN). The gate insulating layer 112 can comprise a material with a high dielectric constant. For example, the gate insulating layer 112 can comprise a high-k material, such as hafnium oxide (HfO₂). The gate insulating layer 112 can have a multilayer structure, but is not limited to this. The intermediate insulating layer 113 can be arranged on top of the gate-insulating layer 112. The intermediate insulating layer 113 can extend between a gate electrode and a source electrode of a transistor, and between the gate electrode and a drain electrode of the transistor. For example, the source electrodes SE1 and SE2 and the drain electrodes DE1 and DE2 of the first transistor T1 and the second transistor T2, respectively, can be insulated from the gate electrodes GE1 and GE2 by the intermediate insulating layer 113. The intermediate insulating layer 113 can cover the gate electrodes GE1 and GE2 of the first transistor T1 and the second transistor T2, respectively. The source electrodes SE1 and SE2 and the drain electrodes DE1 and DE2 of each of the subpixels RSP, GSP, and BSP can be arranged on the intermediate insulating layer 113.The gate-insulating layer 112 and the intermediate insulating layer 113 can expose source regions and drain regions of each semiconductor layer ACT1 or ACT2. The intermediate insulating layer 113 can comprise an insulating material. For example, the intermediate insulating layer 113 can comprise an inorganic insulating material, such as silicon dioxide (SiO₂) and silicon nitride (SiN). The intermediate insulating layer 113 can be arranged on top of the gate insulating layer 112, but is not limited to this. The lower protective layer 114 can be arranged on the intermediate insulating layer 113. The lower protective layer 114 can suppress damage to a drive section caused by external moisture and influences. The lower protective layer 114 can extend along a surface of the first transistor T1 and the second transistor T2. The lower protective layer 114 can contact the intermediate insulating layer 113 outside the drive section located in each of the subpixels RSP, GSP, and BSP. The lower protective layer 114 may comprise an insulating material. For example, the lower protective layer 114 may comprise an inorganic insulating material, such as silicon dioxide (SiO) and silicon nitride (SiN), but is not limited to this. The coating layer 115 can be arranged on the lower protective layer 114. The coating layer 115 can remove (e.g., flatten) a step caused by the control section of each of the subpixels RSP, GSP, and BSP. For example, the top surface of the coating layer 115 facing the substrate 110 can be a flat surface. The coating layer 115 may comprise an insulating material. The coating layer 115 may comprise a material different from that of the lower protective layer 114. For example, the coating layer 115 may comprise an organic insulating material, but is not limited to this. The first transistor T1 can have a first semiconductor layer ACT1, a first gate electrode GE1, a first source electrode SE1 and a first drain electrode DE1. For example, the first semiconductor layer ACT1 can be located between the buffer layer 111 and the gate insulating layer 112, and the first gate electrode GE1 can be located between the gate insulating layer 112 and the intermediate insulating layer 113. The first source electrode SE1 and the first drain electrode DE1 can be located between the intermediate insulating layer 113 and the lower protective layer 114. The first gate electrode GE1 can overlap a channel region of the first semiconductor layer ACT1. The first source electrode SE1 can be electrically connected to a source region of the first semiconductor layer ACT1. The first drain electrode DE1 can be electrically connected to a drain region of the first semiconductor layer ACT1. The second transistor T2 can have a second semiconductor layer ACT2, a second gate electrode GE2, a second source electrode SE2 and a second drain electrode DE2. For example, the second semiconductor layer ACT2 can be located in the same layer as the first semiconductor layer ACT1, the second gate electrode GE2 can be located in the same layer as the first gate electrode GE1, and the second source electrode SE2 and the second drain electrode DE2 can be located in the same layer as the first source electrode SE1 and the first drain electrode DE1. The first transistor T1 can be formed simultaneously with the second transistor T2. However, the first transistor T1 and the second transistor T2 can be controlled individually by different signals. The first light-emitting diode ED1 and the second light-emitting diode ED2 of each of the subpixels RSP, GSP, and BSP can be arranged on the coating layer 115 of the respective subpixels RSP, GSP, and BSP. For example, the first light-emitting diode ED1 can be arranged on the coating layer 115 of the first subpixel SP1, and the second light-emitting diode ED2 can be arranged on the coating layer 115 of the second subpixel SP2. The first light-emitting diode ED1 and the second light-emitting diode ED2 can emit light representing a specific color. For example, the first light-emitting diode ED1 can have a first lower electrode 131, a first emission layer 132, and a first upper electrode 133, which are layered sequentially onto the substrate 110. For example, the first lower electrode 131 of the first light-emitting diode ED1 can be electrically connected to the first drain electrode DE1 (or the first source electrode SE1) of the first transistor T1 through a contact hole penetrating the lower protective layer 114 and the coating layer 115, and the second lower electrode 141 of the second light-emitting diode ED2 can be electrically connected to the second drain electrode DE2 (or the second source electrode SE2) of the second transistor T2 through a contact hole penetrating the lower protective layer 114 and the coating layer 115. The first lower electrode 131 can be an anode electrode of the first light-emitting diode ED1, and the first upper electrode 133 can be a cathode electrode of the first light-emitting diode ED1. For example, the first lower electrode 131 can have a multilayer structure comprising a reflective layer and a transparent conductive layer, and can have a structure in which the reflective layer is arranged between a plurality of transparent conductive layers. For example, the first lower electrode 131 can comprise a metal, such as aluminum (Al) and silver (Ag), and can be formed from a transparent conductive material, such as indium tin oxide (ITO) or indium zinc oxide (IZO), but is not limited to these. The first emission layer 132 can generate light with a luminance corresponding to a voltage difference between the first lower electrode 131 and the first upper electrode 133. For example, the first emission layer 132 can have an emission material layer (EML) comprising an emission material. The emission material can be an organic material, an inorganic material, or a hybrid material. The first emission layer 132 can have a multilayer structure. For example, the first emission layer 132 can further comprise at least one hole injection layer (HIL), one hole transport layer (HTL), one electron transport layer (ETL), and one electron injection layer (EIL). The first upper electrode 133 can be made of a conductive material. The first upper electrode 133 can be made of a material different from that of the first lower electrode 131. The transmittance of the first upper electrode 133 can be higher than that of the first lower electrode 131. For example, the first upper electrode 133 can be a transparent electrode made of a transparent conductive material, such as ITO and IZO. Alternatively, the first upper electrode 133 can be a transparent electrode made of a very thin metal material. Accordingly, in the display device 100 according to an exemplary embodiment of the present disclosure, light generated by the first emission layer 132 can be emitted through the first upper electrode 133. The second light-emitting diode ED2 can implement the same color as the first light-emitting diode ED1, which is located in the same subpixel RSP, GSP, or BSP. The second light-emitting diode ED2 can have a second lower electrode 141, a second emission layer 142, and a second upper electrode 143, which are sequentially layered onto the substrate 110. In this configuration, the second lower electrode 141 can be the anode electrode of the second light-emitting diode ED2, and the second upper electrode 143 can be the cathode electrode of the second light-emitting diode ED2. For example, the second lower electrode 141 can have a multilayer structure comprising a reflective layer and a transparent conductive layer, and can have a structure in which the reflective layer is arranged between a plurality of transparent conductive layers. For example, the second lower electrode 141 can comprise a metal, such as aluminum (Al) and silver (Ag), and can be formed from a transparent conductive material, such as indium tin oxide (ITO) and indium zinc oxide (IZO), but is not limited to these. The second emission layer 142 can generate light with a luminance corresponding to a voltage difference between the second lower electrode 141 and the second upper electrode 143. For example, the second emission layer 142 can have an emission material layer (EML) comprising an emission material. The emission material can be an organic material, an inorganic material, or a hybrid material. The second emission layer 142 can have a multilayer structure. For example, the second emission layer 142 can further comprise at least one hole injection layer (HIL), one hole transport layer (HTL), one electron transport layer (ETL), and one electron injection layer (EIL). The second upper electrode 143 can be made of a conductive material. The second upper electrode 143 can be made of a material different from that of the second lower electrode 141. The transmittance of the second upper electrode 143 can be higher than that of the second lower electrode 141. For example, the second upper electrode 143 can be a transparent electrode made of a transparent conductive material, such as ITO and IZO. Alternatively, the second upper electrode 143 can be a transparent electrode made of a very thin metal material. Accordingly, in the display device 100 according to an exemplary embodiment of the present disclosure, light generated by the second emission layer 142 can be emitted through the second upper electrode 143. The second lower electrode 141 of each of the subpixels RSP, GSP, and BSP can be positioned at a distance from the first lower electrode 131 of the corresponding subpixel RSP, GSP, or BSP. For example, an insulating dam layer 116 can be positioned between the first lower electrode 131 and the second lower electrode 141 of each of the subpixels RSP, GSP, and BSP. The insulating dam layer 116 can comprise an insulating material. For example, the dam insulating layer 116 can comprise an organic insulating material. The dam insulating layer 116 can comprise a material different from, but is not limited to, the coating layer 115. The second lower electrode 141 of each of the subpixels RSP, GSP, and BSP can be insulated from the first lower electrode 131 of the corresponding subpixel RSP, GSP, or BSP by the dam-insulating layer 116. For example, the insulating dam layer 116 can cover a margin of the first lower electrode 131 and a margin of the second lower electrode 141 located in each of the subpixels RSP, GSP, and BSP. The insulating dam 116 can separate an emission region of the first light-emitting diode ED1 and an emission region of the second light-emitting diode ED2. For example, the emission region of the first light-emitting diode ED1 can be defined by a boundary region of the first lower electrode 131 covered by the insulating dam 116. The emission region of the second light-emitting diode ED2 can be defined by a boundary region of the second lower electrode 141 covered by the insulating dam 116. The first emission layer 132 and the first upper electrode 133 of the first light-emitting diode ED1, which is arranged in each of the subpixels RSP, GSP, and BSP, can be arranged on the first lower electrode 131 and the insulating dam layer 116. In particular, the first emission layer 132 and the first upper electrode 133 can be layered on a section of the first lower electrode 131 exposed by the insulating dam layer 116 and on the insulating dam layer 116. The second emission layer 142 and the second upper electrode 143 of the second light-emitting diode ED2, which is arranged in each of the subpixels RSP, GSP, and BSP, can be arranged on the second lower electrode 141 and the insulating dam layer 116.In particular, the second emission layer 142 and the second upper electrode 143 can be layered on a section of the second lower electrode 141 that is exposed through the insulating dam layer 116, and on the insulating dam layer 116. The second upper electrode 143 of each of the subpixels RSP, GSP, and BSP can be electrically connected to the first upper electrode 133 of the corresponding subpixel RSP, GSP, or BSP. For example, a voltage applied to the second upper electrode 143 of the second light-emitting diode ED2, located in each of the subpixels RSP, GSP, and BSP, can be the same as a voltage applied to the first upper electrode 133 of the first light-emitting diode ED1, located in the corresponding subpixel RSP, GSP, or BSP. The second upper electrode 143 of each of the subpixels RSP, GSP, and BSP can be made of the same material as the first upper electrode 133 of the corresponding subpixel RSP, GSP, or BSP. For example, the second upper electrode 143 of each of the subpixels RSP, GSP and BSP can be formed simultaneously with the first upper electrode 133 of the corresponding subpixel RSP, GSP or BSP.The second upper electrode 143 of each of the subpixels RSP, GSP and BSP can extend to an upper surface of the insulating dam layer 116 in such a way that it directly contacts the first upper electrode 133 of the corresponding subpixel RSP, GSP or BSP. An encapsulation element 150 can be arranged over the first light-emitting diode ED1 and the second light-emitting diode ED2 of each of the subpixels RSP, GSP, and BSP. The encapsulation element 150 can suppress damage to the light-emitting diodes ED1 and ED2 caused by external moisture and other influences. The encapsulation element 150 can have a multilayer structure. For example, the encapsulation element 150 can have a first encapsulation layer 151, a second encapsulation layer 152, and a third encapsulation layer 153, which are stacked successively; however, the exemplary embodiments of the present disclosure are not limited to these. The first encapsulation layer 151, the second encapsulation layer 152, and the third encapsulation layer 153 can comprise an insulating material. The second encapsulation layer 152 can comprise a material different from that of the first encapsulation layer 151 and the third encapsulation layer 153. For example, the first encapsulation layer 151 and the third encapsulation layer 153 can be inorganic encapsulation layers comprising an inorganic insulating material, and the second encapsulation layer 152 can be an organic encapsulation layer comprising an organic insulating material. Accordingly, the light-emitting diodes ED1 and ED2 of the display device 100 can be more effectively protected from damage caused by external moisture and other influences. A contact buffer layer 117 can be arranged on the encapsulation element 150. The contact buffer layer 117 can be formed from an inorganic insulating material, such as silicon nitride (SiNx) or silicon oxide (SiOx). The contact buffer layer 117 can be formed by layers of a plurality of insulating layers, but is not limited to this. A plurality of bridge electrodes BE can be arranged on the contact buffer layer 117. The plurality of bridge electrodes BE can be arranged in a layer that is different from a plurality of contact electrodes TE and can be configured to be connected between the plurality of contact electrodes TE. A contact insulation layer 118 can be arranged on the majority of bridge electrodes BE. The contact insulation layer 118 can, for example, be made of an inorganic insulating material or an organic insulating material. Accordingly, the contact insulation layer 118 can electrically insulate the majority of contact electrodes TE and the majority of bridge electrodes BE. A black matrix BM can be arranged on the contact insulation layer 118. The black matrix BM can be arranged such that it suppresses color mixing between the majority of subpixels RSP, GSP, and BSP. Accordingly, the black matrix BM can be arranged such that it overlaps the insulating barrier layer 116. An opening region can be arranged in the black matrix BM such that light generated by the first light-emitting diode ED1 and the second light-emitting diode ED2 is emitted upwards through the black matrix BM. The opening region of the black matrix BM can be arranged such that it corresponds to the emission regions of the first light-emitting diode ED1 and the second light-emitting diode ED2.For example, the opening region of the black matrix BM can overlap, at least partially, with the emission regions of the first light-emitting diode ED1 and the second light-emitting diode ED2. A center point of the opening region of the black matrix BM, corresponding to the first light-emitting diode ED1, can be located at a predetermined distance from or offset relative to the center point of the first light-emitting diode ED1 in a first direction (the left direction). Furthermore, a center point of the opening region of the black matrix BM, corresponding to the second light-emitting diode ED2, can be located at a predetermined distance from or offset relative to the center point of the second light-emitting diode ED2 in a second direction (the right direction).Likewise, in accordance with one embodiment, the black matrix BM can be arranged between two adjacent lenses, and a section of the black matrix BM can overlap one of the two adjacent lenses while not overlapping the other lens of the two adjacent lenses; however, embodiments are not limited to this. A contact insulation layer 119a can be arranged on the black matrix BM. The contact insulation layer 119a can be arranged between the black matrix BM and the plurality of contact electrodes TE and can be configured to insulate the plurality of contact electrodes TE. The contact insulation layer 119a may comprise an insulating material. For example, the contact insulation layer 119a may comprise an organic insulating material or an inorganic insulating material, but is not limited to this. A first additional insulating layer 119b1 and a second additional insulating layer 119b2 can be arranged on the contact insulation layer 119a. The first additional insulating layer 119b1 can be located in the first subpixel SP1 on the contact insulation layer 119a, and the second additional insulating layer 119b2 can be located in the second subpixel SP2 on the contact insulation layer 119a. The first additional insulating layer 119b1 and the second additional insulating layer 119b2 can be spaced apart from each other. The first additional insulating layer 119b1 can have a first inclined surface overlapping the first light-emitting diode ED1 on the contact insulation layer 119a, and the second additional insulating layer 119b2 can have a second inclined surface overlapping the second light-emitting diode ED2 on the contact insulation layer 119a. For example, a cross-section of each of the first additional insulating layer 119b1 and the second additional insulating layer 119b2 can have a triangular shape, but embodiments are not limited thereto. The first inclined surface and the second inclined surface can be inclined in different directions. For example, as shown in Fig. 4, the first additional insulating layer 119b1 can have the first inclined surface, which decreases in height from the center of the first light-emitting diode ED1 in a first direction (e.g., the left direction). As shown in Fig. 5, the second additional insulating layer 119b2 can have the second inclined surface, which decreases in height from the center of the second light-emitting diode ED2 in a second direction (e.g., the right direction). The first additional insulating layer 119b1 and the second additional insulating layer 119b2 can comprise an insulating material. For example, the first additional insulating layer 119b1 and the second additional insulating layer 119b2 can comprise an organic insulating material or an inorganic insulating material, but are not limited to this. The first additional insulating layer 119b1 and the second additional insulating layer 119b2 can be formed by a process separate from the contact insulation layer 119a, however, the first additional insulating layer 119b1 and the second additional insulating layer 119b2 can also be formed integrally with the contact insulation layer 119a, and the present disclosure is not limited to this. A first light path modifying element 161 and a second light path modifying element 162 can be arranged on the first additional insulating layer 119b1 and the second additional insulating layer 119b2, respectively. The first light path modifying element 161 can be arranged on the first inclined surface of the first additional insulating layer 119b1, and the second light path modifying element 162 can be arranged on the second inclined surface of the second additional insulating layer 119b2. This means that the first light path modifying element 161 and the second light path modifying element 162 can be arranged on inclined surfaces, each inclined in different directions. The first light path modifying element 161 can be arranged to correspond to the first light-emitting diode ED1. For example, light generated by the first light-emitting diode ED1 of a subpixel RSP, GSP, or BSP can be emitted in the first direction (e.g., the left direction) by the first light path modifying element 161 of the corresponding subpixel RSP, GSP, or BSP. For example, an optical axis of light generated by the first light-emitting diode ED1 of the subpixel RSP, GSP, or BSP can be tilted by the first light path modifying element 161 from a vertical axis at the center of the first light-emitting diode ED1 at a predetermined angle in the direction of the first direction (e.g., the left direction).Accordingly, the left-hand content L, provided by the first light path change part 161 of a pixel PX, can be provided to, for example, a driver of the vehicle, but is not limited to this. The second light path modifying element 162 can be arranged to correspond to the second light-emitting diode ED2. For example, light generated by the second light-emitting diode ED2 of a subpixel RSP, GSP, or BSP can be emitted in the second direction (e.g., the right direction) by the second light path modifying element 162 of the corresponding subpixel RSP, GSP, or BSP. For example, an optical axis of light generated by the second light-emitting diode ED2 of the subpixel RSP, GSP, or BSP can be tilted by the second light path modifying element 162 from a vertical axis in the center of the second light-emitting diode ED2 at a predetermined angle in the direction of the second direction (e.g., the right direction).Accordingly, the right-hand content R, provided by the second light path modification part 162 of a pixel PX, can be provided, for example, to a passenger sitting in the passenger seat of the vehicle, but is not limited to this. The inclination angle of the first inclined surface and the second inclined surface, on which the first light path modifying element 161 and the second light path modifying element 162 are arranged in an associated manner, can be 20° to 30° (e.g., 25°). This means that the first light path modifying element 161 and the second light path modifying element 162 can be arranged on inclined surfaces with an inclination angle of 20° to 30° (e.g., 25°). For example, the first light path modifying element 161 and the second light path modifying element 162 can be lenses formed by a thermal melting process.In this situation, if the inclination angle of the first inclined surface and the second inclined surface on which the first light path modifying element 161 and the second light path modifying element 162 are arranged is excessively high, the first light path modifying element 161 and the second light path modifying element 162, for example, cannot maintain a hemispherical shape and cannot function as light path modifying elements. Accordingly, by forming the inclination angle of the first inclined surface and the second inclined surface as 20° to 30° (e.g., 25°), the first light path modifying element 161 and the second light path modifying element 162 can be formed stably. For example, the lenses can be placed on surfaces inclined at an angle of 20° to 30° (e.g., 25°).This specific area can be optimal because if the angle is too steep, the lenses may not form a suitable shape during manufacturing and could be shifted to one side; conversely, if the angle is not steep enough, the two separate views cannot be reliably provided, and distortions may occur. This specific area ensures that the lenses can be formed stably and function correctly. Multiple touch electrodes TE can be arranged on the touch insulation layer 119a. Multiple touch electrodes TE can be arranged in the active area above the first light-emitting diode ED1 and the second light-emitting diode ED2. Multiple touch electrodes TE can be spaced apart on the touch insulation layer 119a. Multiple touch electrodes TE can be configured to detect external touch input using a user's finger or a stylus. Referring to Fig. 4 and Fig. 5, the majority of contact electrodes TE can be arranged such that they overlap the insulating dam layer 116 and the black matrix BM. Accordingly, the majority of contact electrodes TE can be configured to minimize the restriction of the light path of light generated by the first light-emitting diode ED1 and the second light-emitting diode ED2. For example, the majority of contact electrodes (TE) may be made of a metallic material, such as titanium (Ti), aluminum (Al), silver (Ag), copper (Cu) or a magnesium-silver alloy (Mg:Ag), but are not limited to this. In the plurality of contact electrodes TE, an opening region between the plurality of contact electrodes TE can be arranged such that light emitted by the first light-emitting diode ED1 and the second light-emitting diode ED2 is emitted upwards between the plurality of contact electrodes TE. The opening region between the plurality of contact electrodes TE can be arranged such that it corresponds to the emission regions of the first light-emitting diode ED1 and the second light-emitting diode ED2. For example, the opening region between the plurality of contact electrodes TE can overlap at least partially with the emission regions of the first light-emitting diode ED1 and the second light-emitting diode ED2.A center of the opening region between the plurality of contact electrodes TE, corresponding to the first light-emitting diode ED1, can be positioned in a first direction (the left direction) at a predetermined distance from the center of the first light-emitting diode ED1. Furthermore, a center of the opening region between the plurality of contact electrodes TE, corresponding to the second light-emitting diode ED2, can be positioned in a second direction (the right direction) at a predetermined distance from the center of the second light-emitting diode ED2. For example, there are openings between the contact electrodes to allow light to pass through the contact detection layer.These openings can be aligned with the light-emitting subpixels below them and can also be intentionally shifted to the left for left-facing light and to the right for right-facing light. Referring to Fig. 3B, Fig. 3C, Fig. 4 and Fig. 5, a first barrier part BR1 can be arranged on the first light path modifying part 161, and a second barrier part BR2 can be arranged on the second light path modifying part 162. The first barrier part BR1 and the second barrier part BR2 can be arranged at a distance from each other. The first barrier part BR1 and the second barrier part BR2 cover a section of the upper surface of the first light path modifying part 161 and the second light path modifying part 162. The first barrier part BR1 covers a section of the upper surface of the first light path modifying part 161. The second barrier part BR2 covers a section of the upper surface of the second light path modifying part 162. The first barrier part BR1 covers a section of the upper surface of the first light path modifying part 161 that is located on a side which has a higher height on both sides of the first inclined surface of the first additional insulating layer 119b1. The second barrier part BR2 covers a section of the upper surface of the second light path modifying part 162 that is located on a side which has a higher height on both sides of the second inclined surface of the second additional insulating layer 119b2. Referring to Fig. 3B and Fig. 4, the first barrier part BR1 is configured to expose a section of the upper surface of the first light path modifying part 161 in the first direction (the left direction) and to cover a section of the upper surface of the first light path modifying part 161 in the second direction (the right direction). Accordingly, the first barrier part BR1 can be configured to not restrict light emitted by the first light path modifying part 161 in the first direction (the left direction) and to block light emitted by the first light path modifying part 161 in the second direction (the right direction). In this situation, referring to Fig. 3B, the surface shape of the first barrier part BR1, which overlaps the first light path-changing part 161, can be arranged such that a side surface oriented in the first direction (the left direction) has an inwardly concave shape. For example, the surface shape of the first barrier part BR1, which overlaps the first light path-changing part 161, can be a crescent shape in which the thickness in the horizontal direction is greater than the thickness in the vertical direction. This means that a surface shape of the first light path-changing part 161, which is exposed by the first light path-changing part 161, can be an elliptical shape, but is not limited to this. If the surface shape of the first barrier element BR1, which overlaps the first light-path-modifying element 161, is, for example, a crescent shape in which a side surface oriented in the first direction (the left direction) has an inward concave shape, the first barrier element BR1 can be configured to further expose the first light-path-modifying element 161 by a size corresponding to the concave shape in the planar surface. Accordingly, the first barrier element BR1 can maximize the exposed size of the first light-path-modifying element 161, thereby minimizing the size of the first barrier element BR1 that blocks light emitted by the first light-path-modifying element 161. Therefore, the light emission efficiency of light emitted by the first light-path-modifying element 161 can be improved. Similarly, the surface shape of the first barrier part BR1, which overlaps the first light path change part 161, can be arranged such that a side surface oriented in the first direction (the left direction) has a linear shape. For example, the surface shape of the first barrier part BR1, which overlaps the first light path change part 161, can be a semicircular shape with a straight side surface in the first direction (the left direction). This means that the surface shape of the first light path change part 161, which is exposed by the first light path change part 161, can be a semicircular shape, but is not limited to this. If the surface shape of the first barrier part BR1, which overlaps the first light path modifying part 161, is, for example, a semicircular shape with a straight side surface oriented in the first direction (the left direction), the first barrier part BR1 can be configured to further shield the first light path modifying part 161 by an area corresponding to the semicircular shape of the surface. Accordingly, the first barrier part BR1 can be configured to more reliably shield light emitted by the first light path modifying part 161 in a direction other than the first direction (the left direction). Therefore, the dual display of the display device 100 can be implemented more reliably. For example, a light-blocking barrier (e.g.,The first barrier portion (BR1) is applied to a section of each lens such that it prevents light from propagating in the wrong direction. For a lens that directs light to the left, the barrier can be applied over the right side of the lens, leaving the left side exposed. Similarly, according to embodiments, the first barrier portion (BR1) can have a crescent shape in a top view such that the exposed area of ​​the lens is maximized, which can improve overall brightness and efficiency. According to another embodiment, the first barrier portion (BR1) can have a semicircular shape in a top view such that it better blocks stray light and reliably separates the two images. Referring to Fig. 3C and Fig. 5, the second barrier part BR2 is configured to expose a section of the upper surface of the second light path modifying part 162 in the second direction (the right direction) and to cover a section of the upper surface of the second light path modifying part 162 in the first direction (the left direction). Accordingly, the second barrier part BR2 can be configured to not restrict light emitted by the second light path modifying part 162 in the second direction (the right direction) and to block light emitted by the second light path modifying part 162 in the first direction (the left direction). In this situation, referring to Fig. 3C, a surface shape of the second barrier part BR2, which overlaps the second light path modifying part 162, can be arranged such that a side surface oriented in the second direction (the right direction) has an inwardly concave shape. For example, the surface shape of the second barrier part BR2, which overlaps the second light path modifying part 162, can be a crescent shape in which a thickness in the horizontal direction is greater than a thickness in the vertical direction. This means that a surface shape of the second light path modifying part 162, which is exposed by the second light path modifying part 162, can be an elliptical shape, but is not limited to this. If the surface shape of the second barrier part BR2, which overlaps the second light path modifying part 162, is, for example, a crescent shape in which a side surface oriented in the second direction (the right direction) has an inward concave shape, the second barrier part BR2 can be configured to further expose the second light path modifying part 162 by an amount corresponding to the concave shape in the surface. Accordingly, the second barrier part BR2 can maximize the exposed size of the second light path modifying part 162, thereby minimizing the size of the second barrier part BR2 that blocks light emitted by the second light path modifying part 162. Therefore, the light emission efficiency of light emitted by the second light path modifying part 162 can be improved. Similarly, the surface shape of the second barrier part BR2, which overlaps the second light path change part 162, can be arranged such that a side surface oriented in the second direction (the right direction) has a linear shape. For example, the surface shape of the second barrier part BR2, which overlaps the second light path change part 162, can be a semicircular shape with a straight side surface in the second direction (the right direction). This means that the surface shape of the second light path change part 162, which is exposed by the second light path change part 162, can be a semicircular shape, but is not limited to this. If the surface shape of the second barrier part BR2, which overlaps the second light path modifying part 162, is, for example, a semicircular shape with a straight side surface oriented in the second direction (the right direction), the second barrier part BR2 can be configured to further shield the second light path modifying part 162 by an area corresponding to the semicircular shape of the surface. Accordingly, the second barrier part BR2 can be configured to more reliably shield light emitted by the second light path modifying part 162 from light emitted in a direction other than the second direction (the right direction). Therefore, the dual display of the display device 100 can be implemented more reliably. For example, a light-blocking barrier (e.g.,The second barrier portion (BR2) is applied to a section of each lens such that it prevents light from propagating in the wrong direction. For a lens that directs light to the right, the barrier can be applied over the left side of the lens, leaving the right side exposed. Similarly, according to embodiments, the second barrier portion (BR2) can have a crescent shape in a top view such that the exposed area of ​​the lens is maximized, which can improve overall brightness and efficiency. According to another embodiment, the second barrier portion (BR2) can have a semicircular shape in a top view such that it better blocks stray light and reliably separates the two images. The first barrier part BR1 and the second barrier part BR2 can be made of a material that, for example, has the property of shielding light. The first barrier part BR1 and the second barrier part BR2 can be made of the same material as the majority of the contact electrodes TE, but are not limited to this. For example, if the first barrier part BR1 and the second barrier part BR2 are formed from the same material as the plurality of touch electrodes TE, the first barrier part BR1 and the second barrier part BR2 can be arranged without providing space for adding separate wiring leads. Similarly, if the first barrier part BR1 and the second barrier part BR2 are formed from the same material as the plurality of touch electrodes TE, an advantageous effect may be to provide space for a wiring design. According to one embodiment, the first barrier part BR1 and the second barrier part BR2 can be part of a corresponding touch electrode, but embodiments are not limited to this.For example, according to one embodiment, the first barrier part BR1 and the second barrier part BR2 can be separated from the contact electrodes, although they can all be made of the same material, and the first barrier part BR1 and the second barrier part BR2 can be electrically potential-free. By arranging a plurality of subpixels in a pixel such that light is emitted in different directions, a dual display technology can be applied to the display device, such that two different contents, for example, contents for a driver of a vehicle and a passenger in a passenger seat, can be viewed using one display panel. However, if the dual display is not stably implemented due to a deterioration in the functionality of multiple lenses that alter light paths in different directions, content may even be visible in a direction opposite to that intended by the lenses. In this situation, a serious safety problem can arise if the person who should not be sharing the content is the driver of the vehicle. In the display device 100 according to an exemplary embodiment of the present disclosure, the first light path modifying part 161 and the second light path modifying part 162 are arranged on a first inclined surface and a second inclined surface, respectively, which are inclined in different directions, and the first barrier part BR1 and the second barrier part BR2, which cover a section of the upper surfaces of the first light path modifying part 161 and the second light path modifying part 162, are arranged. Accordingly, the dual display of the display device 100 can be stably implemented. In particular, in the display device 100 according to an exemplary embodiment of the present disclosure, the first light path modifying element 161 is arranged such that it corresponds to the first light-emitting diode ED1, and the second light path modifying element 162 is arranged such that it corresponds to the second light-emitting diode ED2. The first light path modifying element 161 is arranged on the first inclined surface of the first additional insulating layer 119b1, and the second light path modifying element 162 is arranged on the second inclined surface of the second additional insulating layer 119b2, which is inclined in a direction different from the first inclined surface. The first barrier element BR1 and the second barrier element BR2, which have a light-shielding property, are arranged on the first light path modifying element 161 and the second light path modifying element 162.The first barrier section BR1 and the second barrier section BR2 are arranged such that they cover a portion of the upper surfaces of the first light path modifying section 161 and the second light path modifying section 162. This means that the first barrier section BR1 can be configured to not restrict light emitted by the first light path modifying section 161 in the first direction (e.g., the left direction) and to block light emitted by the first light path modifying section 161 in the second direction (e.g., the right direction). Furthermore, the second barrier section BR2 can be configured to not restrict light emitted by the second light path modifying section 162 in the second direction (e.g., the right direction) and to block light emitted by the second light path modifying section 162 in the first direction (e.g., the left direction).Accordingly, the first barrier part BR1 and the second barrier part BR2 can be configured to block light emitted by the first light path modifying part 161 and the second light path modifying part 162 in directions other than those intended. Therefore, in the display device 100 according to an exemplary embodiment of the present disclosure, by arranging the first light path modifying part 161 and the second light path modifying part 162 on the first inclined surface and the second inclined surface, which are inclined in different directions, and by arranging the first barrier part BR1 and the second barrier part BR2 to cover a section of the upper surfaces of the first light path modifying part 161 and the second light path modifying part 162, the dual display of the display device 100 can be stably implemented and the reliability of the dual display function can be improved.Accordingly, serious safety problems caused by sharing content that should not be shared with the driver of the vehicle can be minimized. Fig. 6 is an enlarged top view of a pixel of a display device according to a further exemplary embodiment of the present disclosure. Fig. 7 is a cross-sectional view along a line CC' of Fig. 6. The display device 600 of Fig. 6 and Fig. 7 differs from the display device 100 of Fig. 1, Fig. 2, Fig. 3, Fig. 4 to Fig. 5 only in the shapes of the first additional insulating layer 619b1 and the second additional insulating layer 619b2, and the other configurations are the same, so that a redundant description is omitted. Referring to Fig. 6, in a pixel PX, the first light path change parts 661 and the second light path change parts 662 of a plurality of subpixels RSP, GSP, and BSP can be arranged side by side in a left and a right direction. For example, the first light path change part 661 of the first subpixel SP1 and the second light path change part 662 of the second subpixel SP2, which emit the same color, can be arranged in the same row. This means that the first region 661E of the first subpixel SP1 and the second region 662E of the second subpixel SP2, which emit the same color, can be arranged in the same row. Referring to Fig. 7, the first additional insulating layer 619b1 and the second additional insulating layer 619b2 can be formed in one piece. In the one-piece formed first additional insulating layer 619b1 and the second additional insulating layer 619b2, a first inclined surface of the first additional insulating layer 619b1 can be arranged in a first direction (e.g., the left direction), and a second inclined surface of the second additional insulating layer 619b2 can be arranged in a second direction (e.g., the right direction). For example, a single one-piece insulating layer part can be formed with two surfaces inclined in opposite directions, in which one surface is inclined to the left and the other surface is inclined to the right.Likewise, a cross-section of the one-piece formed first additional insulating layer 619b1 and the second additional insulating layer 619b2 can have a trapezoidal shape. Referring to Fig. 7, the first light path modifying element 661 and the second light path modifying element 662 are arranged in an associated manner on the integrally formed first additional insulating layer 619b1 and second additional insulating layer 619b2. Within the integrally formed first additional insulating layer 619b1 and second additional insulating layer 619b2, the first light path modifying element 661 is arranged on the first inclined surface of the first additional insulating layer 619b1, and the second light path modifying element 662 is arranged on the second inclined surface of the second additional insulating layer 619b2. Accordingly, the first light path modifying element 661 and the second light path modifying element 662, which are arranged on the inclined surfaces in different directions, can be configured to modify light paths in different directions. Referring to Fig. 7, the first barrier part BR1 is arranged on the first light path changer 661, and the second barrier part BR2 is arranged on the second light path changer 662. The first barrier part BR1 and the second barrier part BR2 can be formed in one piece. In this situation, the one-piece formed first barrier part BR1 and second barrier part BR2 can be electrically potential-free. In the display device 600 according to a further exemplary embodiment of the present disclosure, the dual display of the display device 600 can be stably implemented by arranging the first light path modification part 661 and the second light path modification part 662 in an associated manner on the in-piece formed first additional insulating layer 619b1 and second additional insulating layer 619b2. In particular, in the display device 600 according to a further exemplary embodiment of the present disclosure, the first light path modifying element 661 and the second light path modifying element 662 are arranged in an associated manner on the integrally formed first additional insulating layer 619b1 and second additional insulating layer 619b2. The first light path modifying element 661 is arranged on the first inclined surface of the first additional insulating layer 619b1, and the second light path modifying element 662 is arranged on the second inclined surface of the second additional insulating layer 619b2, which is inclined in a direction different from the first inclined surface. In this configuration, a first barrier element BR1 and a second barrier element BR2, which have light-shielding properties, are arranged on the first light path modifying element 661 and the second light path modifying element 662.The first barrier section BR1 and the second barrier section BR2 are arranged such that they cover a portion of the upper surfaces of the first light path modifying section 661 and the second light path modifying section 662. This means that the first barrier section BR1 can be configured to not restrict light emitted by the first light path modifying section 661 in the first direction (e.g., the left direction) and to block light emitted by the first light path modifying section 661 in the second direction (e.g., the right direction). Furthermore, the second barrier section BR2 can be configured to not restrict light emitted by the second light path modifying section 662 in the second direction (e.g., the right direction) and to block light emitted by the second light path modifying section 662 in the first direction (e.g., the left direction).Accordingly, the first barrier part BR1 and the second barrier part BR2 can be configured to block light emitted by the first light path modifying part 661 and the second light path modifying part 662 in a direction other than the intended directions. Therefore, in the display device 600 according to a further exemplary embodiment of the present disclosure, the dual display of the display device 600 can be stably implemented and the reliability of the dual display function can be improved by arranging the first light path modifying part 661 and the second light path modifying part 662 in an associated manner on the integrally formed first additional insulating layer 619b1 and second additional insulating layer 619b2.For example, this configuration can create a reliable dual display by placing lenses on an inclined insulating layer and then adding a light-blocking barrier to each lens. Likewise, each barrier can be positioned to shield the lens and block any light propagating in the wrong direction. Furthermore, the first barrier component, BR1, and the second barrier component, BR2, can be formed as a single piece or as an identical layer and positioned on and between adjacent lenses, which can improve adhesion and prevent detachment. This structure can improve the reliability of the dual display, which is a safety feature to prevent a driver from being distracted by content on the passenger side of a vehicle.Accordingly, serious safety problems caused by sharing content that should not be shared with the driver of the vehicle can be further minimized.
