[0052] Hereinafter, embodiments of the present inventive concept will be described with reference to the accompanying drawings.

[0053] Figure 1 is a perspective view of an electronic device 1000 according to an embodiment of the present inventive concept.

Display area 1000A may further include curved surfaces bent from at least two sides of the flat surface. However, the shape of display area 1000A is not limited thereto. For example, display area 1000A may include only a flat surface, or may further include at least two curved surfaces, for example, four curved surfaces bent from four sides of the flat surface.

[0056] A partial area of ​​the display area 1000A may be defined as a sensing area 1000SA.

Therefore, an image can be displayed through sensing area 1000SA, and an optical signal can be provided through sensing area 1000SA.

[0057] The electronic device 1000 may include an electronic module disposed in an area overlapping with the sensing area 1000SA. The electronic module may receive an optical signal provided from the outside through the sensing area 1000SA, or may output an optical signal through the sensing area 1000SA. For example, the electronic module may be a camera module, a sensor that measures the distance between an object and a smartphone (such as a proximity sensor), a sensor that senses a body part of a user (e.g., a fingerprint, an iris, or a face), or a small light that emits light, but the embodiments of the present invention are not limited thereto.

[0058] The thickness direction of the electronic device 1000 may be a third direction DR3 that is a normal direction of the display area 1000A. The front surface (or upper surface) and the rear surface (or lower surface) of the members constituting the electronic device 1000 may be defined based on the third direction DR3.

A portion of the display device DD may be defined as a sensing area 100SA, and the sensing area 100SA may have a higher transmittance than other areas of the display area 100A. Therefore, the sensing area 100SA may provide natural light from the outside to the camera module CM. The sensing area 100SA is part of the display area 100A and, therefore, may display an image.

[0062] Pixels PX may be provided in the display area 100A. In the display area 100A, a light-emitting element is provided, and in the peripheral area 100N, no light-emitting element is provided.

[0173] The first input sensing electrode CL1 and the second input sensing electrode CL2 may each correspond to the first sensing electrodes E1-1 to E1-5 (see Figure 7 ) and the second sensing electrodes E2-1 to E2-4 (see Figure 7 The first input sensing electrode CL1 and the second input sensing electrode CL2 may each overlap the first peripheral area NPXA1 which is the non-emission area of ​​the first area A1.

[0174] The light control layer 300 may include a first cover layer OC1 and a second cover layer OC2. The first cover layer OC1 may be disposed on the second sensing insulating layer IL2 of the input sensor 200. The second cover layer OC2 may be disposed on the first cover layer OC1. The first cover layer OC1 and the second cover layer OC2 may each include an organic material. For example, at least one of the first cover layer OC1 and the second cover layer OC2 may include at least one of an acrylic resin, a methacrylic resin, a polyisoprene resin, a vinyl resin, an epoxy resin, a urethane resin, a cellulose resin, a siloxane resin, a polyimide resin, a polyamide resin, and a perylene resin.

[0175] The first light-blocking pattern BM1 (see Figure 12 ) and the second light-blocking pattern BM2 (see Figure 12 ) may not overlap with the first area A1. Accordingly, the 1-1 to 1-3 light emitting elements LD1-B, LD1-G, and LD1-R (see Figure 5A ) may not be blocked by the first and second light-blocking patterns BM1 and BM2 (see Figure 12 ) is blocked and can therefore be viewed at a wider viewing angle.

[0176] The anti-reflection layer 400 may be disposed on the light-controlling layer 300. The anti-reflection layer 400 may be bonded to the light-controlling layer 300 through an adhesive layer. The anti-reflection layer 400 may reduce reflectivity of external light.

[0177] Figure 12 According to the embodiment of the present invention, Figure 9 and Figure 10 Specifically, Figure 12 The display panel 100, the input sensor 200, the light control layer 300 and the anti-reflection layer 400 are stacked. Figure 9 and Figure 10 A cross-sectional view taken along line IV-IV'. Figure 12 The display panel 100, the input sensor 200, the light control layer 300 and the anti-reflection layer 400 shown in FIG may correspond to the reference Figure 3 The display panel 100 , the input sensor 200 , the light control layer 300 and the anti-reflection layer 400 are described.

[0178] Figure 12 The cross-sectional view of the region of the second area A2 overlapping with the 2-1st light-emitting region PXA-B2 is exemplarily illustrated. Accordingly, the cross-sectional view to be described below can be commonly applied to the 2-2nd light-emitting region PXA-G2 and the 2-3rd light-emitting region PXA-R2 of the second area A2 (see FIG. Figure 4 ).

[0179] refer to Figure 12 The light control layer 300 may include a first cover layer OC1, a second cover layer OC2, a first light blocking pattern BM1 and a second light blocking pattern BM2. The first light blocking pattern BM1 and the second light blocking pattern BM2 may not be disposed in the first area A1 (see Figure 10 ) and may be disposed only in the second area A2. The first light-blocking pattern BM1 may be disposed on the second sensing insulating layer IL2 and covered by the first cover layer OC1. The second light-blocking pattern BM2 may be disposed on the first cover layer OC1 and covered by the second cover layer OC2.

[0180] The first and second input sensing electrodes CL1 and CL2 may each overlap the second peripheral area NPXA2 , which is a non-emission area of ​​the second area A2 .

[0181] The first light-blocking pattern BM1 may be disposed on the same layer as the second input sensing electrode CL2. The first light-blocking pattern BM1 may cover a portion of the second input sensing electrode CL2 that overlaps the second area A2. No additional covering layer may exist between the second input sensing electrode CL2 and the first light-blocking pattern BM1, and therefore, the first light-blocking pattern BM1 may be disposed adjacent to the 2-1st light-emitting element LD2-B in the second area A2. Accordingly, the first light-blocking pattern BM1 may prevent light leakage at a wide viewing angle. This will be referred to later. Figure 13 To describe.

[0182] The first light-blocking pattern BM1 may include a 1-1th light-blocking pattern BM1-1 and a 1-2th light-blocking pattern BM1-2. The 1-1th light-blocking pattern BM1-1 may overlap the first pixel defining layer PDL1. The 1-1th light-blocking pattern BM1-1 may overlap the second peripheral area NPXA2. The light-blocking area BMA may be an area corresponding to the first light-blocking pattern BM1.

[0183] The 1-2nd light-blocking pattern BM1-2 may overlap the second pixel defining layer PDL2 disposed on the first electrode AE. The 1-2nd light-blocking pattern BM1-2 may overlap the first non-emission area NCA-B. In this embodiment, the 1-1st light-blocking pattern BM1-1 and the 1-2nd light-blocking pattern BM1-2 may include the same material and have an interconnected integral pattern.

[0184] The second light-blocking pattern BM2 may include a 2-1st light-blocking pattern BM2-1 and a 2-2nd light-blocking pattern BM2-2. The second light-blocking pattern BM2 may be disposed farther from the display panel 100 than the first light-blocking pattern BM1. The 2-1st light-blocking pattern BM2-1 may overlap the 1-1st light-blocking pattern BM1-1. The 2-1st light-blocking pattern BM2-1 may overlap the second peripheral area NPXA2.

[0185] The 2-2nd light-blocking pattern BM2-2 may overlap the second pixel defining layer PDL2 disposed on the first electrode AE. The 2-2nd light-blocking pattern BM2-2 may overlap the first non-emission area NCA-B. In this embodiment, the 2-1st light-blocking pattern BM2-1 and the 2-2nd light-blocking pattern BM2-2 may include the same material and have an interconnected integral pattern.

[0186] According to the present invention, when the display device DD operates in the second operating mode, light emitted from the 2-1st light-emitting element LD2-B disposed in the second area A2 can be blocked at a predetermined angle by the first light-blocking pattern BM1 and the second light-blocking pattern BM2. In other words, as the viewing angle when viewing the display device DD from the side increases, the light-blocking area becomes larger.

[0187] Therefore, in the second operating mode, the user of the display device DD can view the display area 1000A (see Figure 1 ), but people close to the user cannot see the display area 1000A (see Figure 1 ). Accordingly, a display device DD having an improved private mode function can be provided.

[0188] According to this embodiment, the 1-2nd light-blocking pattern BM1-2 may have a first line width WD1. The 2-2nd light-blocking pattern BM2-2 may have a second line width WD2. The first line width WD1 may be greater than the second line width WD2. Accordingly, the 1-2nd light-blocking pattern BM1-2 adjacent to the 2-1st light-emitting element LD2-B may effectively prevent light leakage at a large viewing angle. This will be referred to later. Figure 13 To describe.

[0189] However, embodiments of the present invention are not limited to the case where the first line width WD1 of the 1-2nd light-blocking pattern BM1-2 is greater than the second line width WD2 of the 2-2nd light-blocking pattern BM2-2. For example, the first line width WD1 of the 1-2nd light-blocking pattern BM1-2 may be the same as the second line width WD2 of the 2-2nd light-blocking pattern BM2-2.

[0190] The first and second line widths WD1 and WD2 may be smaller than the width of the second pixel defining layer PDL2. Therefore, light emitted from the 2-1st light emitting element LD2-B in the 2-1st light emitting region PXA-B2 may not be blocked by the first and second light blocking patterns BM1 and BM2.

[0191] The organic encapsulating layer 142 may have a thickness D1 smaller than the thickness D2 of the first cover layer OC1. In a cross section, a height difference along the third direction DR3 between the 2-1st light emitting element LD2-B and the first light blocking pattern BM1 may be smaller than a height difference between the first light blocking pattern BM1 and the second light blocking pattern BM2.

[0192] The thickness D1 of the organic encapsulation layer 142 may be approximately 6 μm to approximately 12 μm. When the thickness D1 of the organic encapsulation layer 142 is less than approximately 6 μm, the organic encapsulation layer 142 may be too thin to protect the 2-1st light-emitting element LD2-B from external foreign matter. When the thickness D1 of the organic encapsulation layer 142 is greater than approximately 12 μm, the first light-blocking pattern BM1 may be too far away from the 2-1st light-emitting element LD2-B to prevent light leakage at a wide viewing angle.

[0193] The thickness D2 of the first cover layer OC1 may be about 10 μm to about 20 μm. When the thickness D2 of the first cover layer OC1 is less than about 10 μm, the distance between the first light-blocking pattern BM1 and the second light-blocking pattern BM2 may be too close to prevent light leakage at a wide viewing angle. When the thickness D2 of the first cover layer OC1 is greater than about 20 μm, the display device DD as an entire stacked structure may be too thick.

[0194] Figure 13 According to the embodiment of the present invention, Figure 9 and Figure 10 Specifically, Figure 13 The display panel 100, the input sensor 200, the light control layer 300 and the anti-reflection layer 400 are stacked. Figure 9 and Figure 10 A cross-sectional view taken along line IV-IV'.

[0195] refer to Figure 13 , at a viewing angle less than or equal to the first viewing angle α1°, light emitted from the 2-1st light-emitting element LD2-B may pass between the 2-1st light-blocking pattern BM2-1 and the 2-2nd light-blocking pattern BM2-2, as shown in FIG. Figure 13 ① in FIG. At this time, the light emitted from the 2-1st light-emitting element LD2-B may not be blocked by the first light-blocking pattern BM1 or the second light-blocking pattern BM2, and thus, may be viewed by the user. Here, the viewing angle may be the angle between the path of the emitted light and the third direction DR3 extending perpendicularly to the extending direction of the base substrate 110.

[0196] At the second viewing angle α2°, light emitted from the 2-1st light emitting element LD2-B may be blocked by the 1-2nd light-blocking pattern BM1-2. Figure 13As shown in ② in FIG. Here, the second viewing angle α2° is greater than the first viewing angle α1°. At a viewing angle greater than or equal to the first viewing angle α1°, light emitted from the 2-1st light-emitting element LD2-B in the second area A2 can be blocked by the first light-blocking pattern BM1 and cannot be viewed by the user. In other words, at a wide viewing angle, the first light-blocking pattern BM1 can prevent leakage of light emitted from the 2-1st light-emitting element LD2-B.

[0197] The organic encapsulation layer 142 may have a thickness D1 that is smaller than the thickness D2 of the first cover layer OC1. Therefore, the first light-blocking pattern BM1 can be positioned close to the 2-1st light-emitting element LD2-B without significantly changing the thickness of the entire display device DD. When the first light-blocking pattern BM1 is positioned close to the 2-1st light-emitting element LD2-B, light leakage at a wide viewing angle can be effectively prevented.

[0198] The first line width WD1 can be greater than the second line width WD2. Accordingly, at a viewing angle less than or equal to a predetermined viewing angle, light emitted from the 2-1st light-emitting element LD2-B can be unblocked by the first light-blocking pattern BM1 or the second light-blocking pattern BM2. However, at viewing angles exceeding the predetermined viewing angle, the light can be blocked by the first light-blocking pattern BM1. As previously described, since the 1-2nd light-blocking pattern BM1-2 has a large first line width WD1 and the first light-blocking pattern BM1 is positioned close to the 2-1st light-emitting element LD2-B, light leakage at a wider viewing angle can be effectively prevented.

[0199] Figure 14 According to the embodiment of the present invention, Figure 9 and Figure 10 A cross-sectional view taken along line IV-IV'.

[0200] refer to Figure 14 , the display device DD according to this embodiment may further include a protection layer CLA overlapping the second input sensing electrode CL2. Figure 12 The configuration of the display device DD described is the same, so the same reference numerals or symbols are used for the same components, and the description of the same components will be omitted.

[0201] A protective layer CLA may be disposed on the second sensing insulating layer IL2. A portion of the protective layer CLA overlapping the second peripheral area NPXA2 may be disposed between the second input sensing electrode CL2 and the 1-1th light-blocking pattern BM1-1 to cover the second input sensing electrode CL2. Accordingly, the protective layer CLA may cover the second input sensing electrode CL2, thereby protecting the second input sensing electrode CL2 from moisture and oxygen.

[0202] The protective layer CLA may include an inorganic material. For example, the protective layer CLA may include a silicon nitride layer, a silicon oxynitride layer, a silicon oxide layer, a titanium oxide layer, or an aluminum oxide layer. However, this is an example, and the material of the protective layer CLA is not limited thereto, and the protective layer CLA may include various materials.

[0204] refer to Figure 15 In each of the 1-1st light-emitting areas PXA-B1, the 1-2nd light-emitting areas PXA-G1, and the 1-3 light-emitting areas PXA-R1 provided in the first area A1, the light-emitting areas providing light of the same color may be grouped and surrounded by one grid opening MS-OP1. That is, one grid opening MS-OP1 may surround the four 1-1st light-emitting areas PXA-B1, another grid opening MS-OP1 may surround the two 1-2nd light-emitting areas PXA-G1 of the first group, yet another grid opening MS-OP1 may surround the two 1-2nd light-emitting areas PXA-G1 of the second group, and the remaining one grid opening MS-OP1 may surround the four 1-3 light-emitting areas PXA-R1.

[0205] The 1-1st light-emitting region PXA-B1 disposed in the first area A1 may have the same arrangement as the 2-1st light-emitting region PXA-B2 disposed in the second area A2. The 1-2nd light-emitting region PXA-G1 disposed in the first area A1 may have the same arrangement as the 2-2nd light-emitting region PXA-G2 disposed in the second area A2. The 1-3rd light-emitting region PXA-R1 disposed in the first area A1 may have the same arrangement as the 2-3rd light-emitting region PXA-R2 disposed in the second area A2.

[0206] However, the arrangement of each of the 1-1 to 1-3 light emitting areas PXA-B1, PXA-G1, and PXA-R1 provided in the first area A1 is merely an example, and the number and arrangement of each of the 1-1 to 1-3 light emitting areas PXA-B1, PXA-G1, and PXA-R1 may be changed as needed.

[0207] According to the present invention, by reducing the thickness of the encapsulation layer to be smaller than that of the cover layer and placing the first light-blocking pattern close to the light-emitting element, a display device capable of preventing light leakage at a wide viewing angle can be provided.
