Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2023-0166918, filed on November 27, 2023, which is incorporated herein by reference in its entirety as if fully set forth herein. Technical Field

[0002] The present disclosure relates to a display device capable of preventing light leakage. Background Art

[0003] Recently, with the advent of the comprehensive information age, display devices capable of visually presenting electrical information signals have rapidly developed. Accordingly, various display devices such as liquid crystal display (LCD) devices and organic light emitting display (OLED) devices have been developed and used in various fields.

[0004] Among display devices, self-emitting display devices include self-emitting devices as light-emitting devices and thus do not require a separate light source used in non-self-emitting display devices. Therefore, self-emitting display devices have the advantages of light weight and thin profile. In addition, self-emitting display devices have no viewing angle limitation due to their self-emitting characteristics.

[0005] To control the viewing angle for reasons such as privacy protection, information protection, and application to vehicle display devices, such self-emitting display devices may include lenses respectively corresponding to a plurality of light-emitting devices.

[0006] The light emitted from a light-emitting device may not only propagate to the corresponding lens but also diffuse in all directions. At this time, the light emitted from the light-emitting device and propagating to the region between the lenses is reflected by a light-shielding member such as a light-shielding pattern provided between the lenses and is re-reflected by a reflection member included in the light-emitting device. In this way, the light emitted from the light-emitting device reaches a lens that does not correspond to it, which may cause light leakage. This may also cause deterioration of the cut-off effect in a display device where the viewing angle needs to be controlled. Summary of the Invention

[0007] Accordingly, the present disclosure relates to a display device that substantially overcomes one or more problems caused by the limitations and disadvantages of the related art.

[0008] An object of the present disclosure is to provide a display device that can prevent light leakage by preventing the light emitted from a light-emitting device from being reflected by a light-shielding member provided in a non-opening region to the light-emitting device or by adjusting the angle at which the light is reflected to the light-emitting device so that the light re-reflected from the light-emitting device does not reach another lens that does not correspond to the light-emitting device.

The first light-shielding pattern may include a central portion and an edge portion provided around the central portion, and the edge portion may be inclined with respect to the central portion.

[0013] In addition, a display device includes: a plurality of light-emitting devices disposed on a substrate; a first insulating layer disposed on the plurality of light-emitting devices; a plurality of lenses disposed on the first insulating layer, the plurality of lenses being disposed to correspond to the plurality of light-emitting devices respectively; a first light-shielding pattern disposed between the substrate and the first insulating layer, the first light-shielding pattern being disposed to correspond to an area between the plurality of light-emitting devices; a second light-shielding pattern disposed on the first insulating layer, the second light-shielding pattern overlapping with the first light-shielding pattern; and a third light-shielding pattern disposed on the first insulating layer and covering the second light-shielding pattern.

[0031] The advantages, features, and implementation methods of the present disclosure will be clarified by the following embodiments described with reference to the accompanying drawings. However, the present disclosure can be implemented in different forms and should not be construed as limited to the embodiments listed herein. Instead, these embodiments are provided to make the present disclosure comprehensive and complete, and to fully convey the scope of the present disclosure to those skilled in the art. The present disclosure is only limited by the scope of the claims.

[0032] In the drawings for explaining the exemplary embodiments of the present disclosure, for example, the shown shapes, sizes, ratios, angles, and quantities are given by way of example and are thus not limited to the present disclosure. Throughout this application, the same reference numerals denote the same components. In addition, in the following description of the present disclosure, when the detailed description of the known functions and configurations incorporated herein may obscure the subject matter of the present disclosure, the detailed description will be omitted.

[0033] The terms "comprising", "including" and / or "having" used in this application do not exclude the presence or addition of other elements, unless used together with the term "only". The singular form is intended to also include the plural form, unless the context clearly indicates otherwise.

[0034] When interpreting the constituent elements, even if not explicitly described, the constituent elements are interpreted as including the error range.

[0035] When describing each embodiment, when describing the positional relationship, for example, when using descriptions such as "on", "above", "below", "adjacent to" etc. to describe the positional relationship between two parts, one or more other parts may be provided between these two parts, unless the terms "directly" or "closely" are used.

[0036] When describing each embodiment of the present disclosure, when describing the temporal relationship, for example, when using descriptions such as "after", "subsequently", "then", "before" etc. to describe the temporal relationship between two actions, these actions may not occur continuously, unless the terms "directly" or "exactly" are used.

[0037] It can be understood that although terms such as "first", "second" etc. may be used herein to describe each element, these elements should not be limited by these terms. These terms are only used to distinguish one element from another. Therefore, in this application, without exceeding the technical scope of the present disclosure, the element represented by "first" may be the same as the element represented by "second", unless there is a contrary indication.

[0038] The first horizontal axis direction, the second horizontal axis direction and the vertical axis direction should not be interpreted only as a strictly vertical geometric relationship between them, and may represent a wider directivity within the range of operation of the functions of the elements in the present disclosure.

[0039] The term "at least one" should be understood as including all possible combinations that can be proposed from one or more related items. For example, the meaning of "at least one of the first item, the second item or the third item" may be each of the first item, the second item or the third item, or all possible combinations that can be proposed from two or more of the first item, the second item and the third item.

[0040] The various features of each embodiment of the present disclosure may be partially or wholly combined and combined with each other, and various technical associations and patterns of operation are possible. These embodiments may be executed independently of each other or may be executed in association with each other.

[0041] Wherever possible, the same reference numerals will be used throughout the drawings to refer to the same or like parts. Since, for ease of description, the size of each element shown in the drawings is different from the actual size, the present disclosure is not limited to the sizes shown in the drawings.

[0042] Hereinafter, preferred examples of a display device according to an embodiment of the present disclosure will be described in detail with reference to the drawings.

[0043] Figures 1A to 1C is a plan view of the display device of the present disclosure.

[0044] Referring to Figures 1A to 1C , the display device 1000 of the present disclosure may include a plurality of unit pixels. Each of the plurality of unit pixels may include a first sub-pixel SP1, a second sub-pixel SP2, and a third sub-pixel SP3. The first sub-pixel SP1, the second sub-pixel SP2, and the third sub-pixel SP3 may be sub-pixels that emit light of different colors. For example, the first sub-pixel SP1, the second sub-pixel SP2, and the third sub-pixel SP3 may each be a sub-pixel that emits one of red light, green light, and blue light.

[0045] The first sub-pixel SP1, the second sub-pixel SP2, and the third sub-pixel SP3 may have different area ratios. The first lower electrode 171a and the second lower electrode 171b of each of the first sub-pixel SP1, the second sub-pixel SP2, and the third sub-pixel SP3, and the light emitting portion and the open area OA (OA1, OA2) of each of the first sub-pixel SP1, the second sub-pixel SP2, and the third sub-pixel SP3 may have area ratios different from those of the other sub-pixels. The area of each of the first sub-pixel SP1, the second sub-pixel SP2, and the third sub-pixel SP3 may be determined in consideration of the lifespan and luminous efficiency of the light emitting device that emits light of the corresponding color. That is, the sub-pixel that emits short-wavelength light may have a larger area than the other sub-pixels, and the sub-pixel that emits long-wavelength light may have a smaller area than the other sub-pixels. In the present disclosure, the area ratios of the sub-pixels that emit light of different colors are set to be different from each other, so that the lifespan and luminous efficiency of the light emitting devices of the respective sub-pixels become uniform. For example, as Figures 1A to 1C shown, the second sub-pixel SP2 may have a larger area than the first sub-pixel SP1 and the third sub-pixel SP3, and the third sub-pixel SP3 may have a smaller area than the first sub-pixel SP1 and the second sub-pixel SP2. However, the present disclosure is not limited thereto. The arrangement and area ratios of the first sub-pixel SP1, the second sub-pixel SP2, and the third sub-pixel SP3 may be set differently from the above.

[0046] The first sub-pixel SP1 and the second sub-pixel SP2 may be alternately arranged in the second direction D2. The third sub-pixel SP3 may be arranged adjacent to the first sub-pixel SP1 and the second sub-pixel SP2 in a first direction D1 that intersects the second direction D2. Here, the first direction D1 and the second direction D2 may be directions that are perpendicular to each other and intersect. However, the arrangement of the first sub-pixel SP1, the second sub-pixel SP2, and the third sub-pixel SP3 of the present disclosure is not limited thereto.

[0047] Referring to Figure 1B and Figure 1C , each of the first sub-pixel SP1, the second sub-pixel SP2, and the third sub-pixel SP3 may include a first lower electrode 171a and a second lower electrode 171b. The first lower electrode 171a and the second lower electrode 171b may be independently arranged from each other and independently driven by different driving circuits. The second lower electrode 171b may include a plurality of second opening regions OA2. Alternatively, the second lower electrodes may be provided as a plurality corresponding to a plurality of opening regions, respectively.

[0048] The first lower electrode 171a and the second lower electrode 171b may be formed to have different areas. In addition, the first lower electrodes 171a of the first sub-pixel SP1, the second sub-pixel SP2, and the third sub-pixel SP3 may be formed to have different area ratios. The second lower electrodes 171b of the first sub-pixel SP1, the second sub-pixel SP2, and the third sub-pixel SP3 may also be formed to have different area ratios.

[0049] Compared with the second direction D2, the first lower electrode 171a may be longer in the first direction D1. The first lower electrode 171a may include a first opening region OA1. Compared with the second direction D2, the second lower electrode 171b may also be longer in the first direction D1. In addition, the second lower electrode 171b may include a plurality of second opening regions OA2. The regions other than the first opening region OA1 and the second opening region OA2 may be defined as non-open areas.

[0050] The opening regions OA1, OA2 may be regions that emit light. For example, each of the opening regions OA1, OA2 may be a region exposed from the bank ( Figure 3 in 115). The bank may be provided in the light-emitting device ( Figure 3Between 170a). For example, each light-emitting device 170a in which an intermediate layer 173 is provided between the first lower electrode 171a and the upper electrode 175 may emit light in one of the opening regions OA. The opening region OA may include a first opening region OA1 corresponding to the first lower electrode 171a and a second opening region OA2 corresponding to the second lower electrode 171b. The second opening region OA2 may have an area different from that of the first opening region OA1.

[0051] The first opening region OA1 corresponding to the first lower electrode 171a may be provided in the first direction D1 of the first lower electrode 171a. The first opening region OA1 may be longer in the first direction D1 than in the second direction D2.

[0052] A plurality of second opening regions OA2 corresponding to the second lower electrode 171b may be arranged in a row at intervals from each other in the first direction D1 within the second lower electrode 171b. Each of the plurality of second opening regions OA2 may be formed such that its length in the first direction D1 is similar to its length in the second direction D2.

[0053] A first lens L1 corresponding to the first opening region OA1 of the first lower electrode 171a and a plurality of second lenses L2 corresponding to the plurality of second opening regions OA2 of the second lower electrode 171b may be provided. The first lens L1 and the plurality of second lenses L2 may have different shapes. The first lens L1 and each second lens L2 may have different area ratios when viewed in a plan view.

[0054] Consistent with the shape of the first opening region OA1 of the first lower electrode 171a, the first lens L1 may be longer in the first direction D1 than in the second direction D2. The size of the first lens L1 may be formed to cover at least the entire first opening region OA1 of the first lower electrode 171a. In addition, the first lens L1 may be provided above the first lower electrode 171a while having an area larger than that of the first opening region OA1 and at least extending beyond the length of the first lower electrode 171a in the first direction D1. The first lens L1 may be implemented as a semi-cylindrical lens having a length in the first direction D1. For example, the first lens L1 may be implemented as a hemi-ellipsoidal lens cut along its length direction.

[0055] The semi-cylindrical first lens L1 may have a rectangular cross-section when viewed in a plan view and may have a semi-circular cross-section when cut along a cutting line extending in the second direction D2. In addition, the hemi-ellipsoidal first lens L1 may have an elliptical cross-section when viewed in a plan view. Therefore, the first lens L1 may limit the viewing angle in the second direction D2 without limiting the viewing angle in the first direction D1.

[0056] The size of each second lens L2 may be formed to completely cover a corresponding one of the plurality of second opening regions OA2 of the second lower electrode 171b. In addition, the length of each second lens L2 in the first direction D1 may be less than the length of the first lens L1 in the first direction D1. Each of the plurality of second lenses L2 may be implemented as a hemispherical lens.

[0057] The hemispherical second lens L2 may have a circular cross-section when viewed in a plan view, and may have a semi-circular cross-section when cut along a cutting line extending in the first direction D1 and when cut along a cutting line extending in the second direction D2. Such a hemispherical second lens L2 may limit the viewing angle in the first direction D1 and the second direction D2.

[0058] As described above, the display device of the present disclosure may be a viewing angle control display device capable of limiting the viewing angle using the semi-ellipsoidal first lens L1 corresponding to the first lower electrode 171a and the plurality of hemispherical second lenses L2 corresponding to the second lower electrodes 171b. Since the directions in which the first lens L1 limits the viewing angle and the second lens L2 limits the viewing angle are different from each other, the display device of the present disclosure may selectively achieve a wide viewing angle and a narrow viewing angle.

[0059] Figure 2 is a plan view of a display device according to the first and second embodiments of the present disclosure. In Figure 2 Since the plan view of the first embodiment and the plan view of the second embodiment are the same as each other, the reference numerals of the first embodiment are representatively used. Figure 3 is Figure 2 a cross-sectional view of a light-emitting array taken along line I-I' in Figure 4A and Figure 4B is Figure 2 a cross-sectional view of the first embodiment taken along line II-II' in Figure 4B shows Figure 4A the path of light emitted from one light-emitting device in the display device of the present disclosure shown in

[0060] Referring to Figure 2 , the display device according to the first embodiment of the present disclosure may include a first light-shielding pattern 210 and a second light-shielding pattern 230 provided in a non-opening region. The first light-shielding pattern 210 and the second light-shielding pattern 230 may have different widths. In the first embodiment, the second width ( Figure 4A W2 in Figure 4A ) of the second light-shielding pattern 230 may be greater than the first width ( W1 in ) of the first light-shielding pattern 210.

[0061] The first light-shielding pattern 210 may be disposed on the entire surface of the substrate 110 while being separated from the edge of the lens 240 to expose the lens 240.

[0062] The second light-shielding pattern 230 may overlap a part of the edge of the lens 240 while at least exposing the opening regions OA1 and OA2 of the lens 240. The second light-shielding pattern 230 may be patterned on the substrate 110 so as to be provided in plurality. The plurality of second light-shielding patterns 230 may be connected to each other via connection patterns disposed therebetween.

[0063] Figure 3 is a cross-sectional view of the light-emitting array 100 disposed on the substrate 110 in the display device of the present disclosure. Refer to Figure 3 , the light-emitting array 100 may include components disposed between the substrate 110 and the encapsulation layer 180. A plurality of transistors TFT, a plurality of light-emitting devices 170a respectively connected to the transistors, and an encapsulation layer 180 covering the plurality of light-emitting devices 170a may be disposed on the substrate 110. The light-emitting device 170a may overlap the opening region OA.

[0064] The substrate 110 may be divided into an effective region of the display screen and a non-effective region where no screen is displayed, and a plurality of sub-pixels (SP1, SP2, SP3 in FIG. 1) may be repeatedly provided in the effective region. The plurality of sub-pixels SP1, SP2, SP3 may include a light-emitting portion that actually emits light and a non-light-emitting portion formed around the light-emitting portion and not emitting light. In the present disclosure, the light-emitting portion may overlap the opening region OA disposed above the substrate 110. For example, when the substrate 110 is a plastic substrate, the substrate 110 may include polyimide or polyamide.

[0065] On the substrate 110, circuit devices may be provided for each light-emitting device 170a, and the circuit devices include various signal lines such as data lines and gate lines; transistors such as driving thin-film transistors, switching thin-film transistors, and sensing thin-film transistors; and capacitors. In the present disclosure, for ease of description, one transistor TFT for driving each light-emitting device 170a is shown.

[0066] The transistor TFT may include an active layer 37, and a gate electrode 43 overlapping the channel region 35 of the active layer 37 with a gate insulating film 41 interposed therebetween, and may include a source electrode 51 and a drain electrode 53 respectively connected to opposite sides of the active layer 37.

[0067] The active layer 37 may include a source region 31 and a drain region 33 respectively disposed on opposite sides thereof, and may include a channel region 35 disposed between the source region 31 and the drain region 33. Each of the source region 31 and the drain region 33 is formed of a semiconductor material doped with an n-type or p-type dopant. The channel region 35 overlapping with the gate electrode 43 may be formed of a semiconductor material not doped with an n-type or p-type dopant.

[0068] The gate electrode 43 and the channel region 35 of the active layer 37 may have the same width and may be disposed to overlap each other with the gate insulating film 41 therebetween. The gate insulating film 41 may overlap with the channel region 35 of the active layer 37 in the same pattern as the gate electrode 43. For example, the gate electrode 43 may take the form of a single layer or a multi-layer made of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), copper (Cu), or an alloy thereof. The gate insulating film 41 may be made of an inorganic insulating material. For example, the gate insulating film 41 may be implemented as a silicon oxide (SiOx) film, a silicon nitride (SiNx) film, a silicon oxynitride (SiOxNy) film, or a multi-layer film thereof.

[0069] The light-shielding layer 21 on the substrate 110 is disposed below the active layer 37 while overlapping at least the channel region 35 of the active layer 37 of the transistor TFT. The light-shielding layer 21 prevents external light from propagating through the substrate 110 to the transistor TFT. For example, the light-shielding layer 21 may be implemented as a single layer made of a metal material such as molybdenum (Mo), titanium (Ti), aluminum-neodymium (AlNd), aluminum (Al), chromium (Cr), or an alloy thereof, or may be formed as a multi-layer structure including the above metal materials.

[0070] A buffer film 111 may be disposed on the light-shielding layer 21 to cover the light-shielding layer 21. For example, the buffer film 111 may take the form of a single layer or a multi-layer made of silicon oxide (SiOx) or silicon nitride (SiNx).

[0071] An interlayer insulating film 112 may be disposed on the buffer film 111. The interlayer insulating film 112 may include a source contact hole and a drain contact hole respectively exposing the source region 31 and the drain region 33 of the active layer 37, and may cover the gate insulating film 41 and the gate electrode 43. For example, the interlayer insulating film 112 may be made of an inorganic insulating material. For example, the interlayer insulating film 112 may be implemented as a silicon oxide (SiOx) film, a silicon nitride (SiNx) film, a silicon oxynitride (SiOxNy) film, or a multi-layer film thereof.

[0072] The source electrode 51 and the drain electrode 53 can be provided in the same layer on the interlayer insulating film 112. The source electrode 51 and the drain electrode 53 are respectively connected to the source region 31 and the drain region 33 of the active layer 37 through a source contact hole and a drain contact hole. For example, each of the source electrode 51 and the drain electrode 53 can take the form of a single layer made of a metal material such as molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), copper (Cu), or their alloys, or can be formed into a multilayer structure including the above metal materials.

[0073] A passivation layer 113 can be provided on the interlayer insulating film 112 to cover the transistor TFT. Therefore, the transistor TFT can be protected by the passivation layer 113. For example, the passivation layer 113 can be an inorganic insulating film and can be realized as a silicon oxide (SiOx) film, a silicon nitride (SiNx) film, a silicon oxynitride (SiOxNy) film, or a multilayer film thereof.

[0074] A planarization film 114 can be provided on the passivation layer 113. The planarization film 114 can be formed to a thickness sufficient to provide a substantially flat surface on the uneven surface above the transistor TFT and can be realized as an organic insulating film. When the planarization film 114 is also used to protect the transistor TFT, the passivation layer 113 can be omitted. For example, the planarization film 114 can be an organic insulating film. For example, the planarization film 114 can be realized as an optical acrylic film, a polyimide film, a benzocyclobutene resin film, or an acrylate film, or in some cases can be realized as a multilayer film thereof.

[0075] A light-emitting device 170a can be provided on the planarization film 114. The light-emitting device 170a includes a first lower electrode 171a, an intermediate layer 173, and an upper electrode 175. The light-emitting device 170a can be driven in such a way that the intermediate layer 173 emits light when an electric field is formed between the first lower electrode 171a and the upper electrode 175.

[0076] The first lower electrode 171a can be formed into a multilayer structure including a transparent conductive film and an opaque conductive film having a high reflection efficiency. The transparent conductive film of the first lower electrode 171a can be formed of a material having a relatively high work function, such as indium tin oxide (ITO) or indium zinc oxide (IZO). The opaque conductive film of the first lower electrode 171a can be formed into a single-layer or multilayer structure including a material selected from the group consisting of silver (Ag), aluminum (Al), copper (Cu), molybdenum (Mo), titanium (Ti), nickel (Ni), chromium (Cr), tungsten (W), and their alloys. For example, the first lower electrode 171a can be formed into a structure in which a transparent conductive film, an opaque conductive film, and a transparent conductive film are stacked in sequence, or can be formed into a structure in which a transparent conductive film and an opaque conductive film are stacked in sequence.

[0077] A bank 115 may be provided on the entire surface of the planarization film 114 to cover the edge of the first lower electrode 171a. The bank 115 may define an opening area OA exposing the light-emitting device 170a. In some cases, the bank 115 may include a light-absorbing material. In this case, the bank 115 may include a black dye. Accordingly, the display device of the present disclosure may prevent optical interference and light leakage between adjacent sub-pixels.

[0078] The intermediate layer 173 may be provided on the first lower electrode 171a, the second lower electrode 171b, and the bank 115 over the entire area of the substrate 110. Specifically, the intermediate layer 173 may be an organic layer having a single-stack structure composed of multiple layers including a hole injection layer, a hole transport layer, a light-emitting layer, an electron transport layer, and an electron injection layer. In some cases, the intermediate layer 173 may be formed in a tandem structure including multiple stacks (a first stack and a second stack), and the multiple stacks respectively include a first light-emitting layer and a second light-emitting layer, and a charge generation layer provided between these stacks. The tandem structure is not limited to a 2-stack structure, but may be a multiple-stack structure including three or more stacks. The first and second light-emitting layers in the multiple stacks may be light-emitting layers that emit the same color of light among red light, green light, and blue light, and may be patterned in each of the plurality of sub-pixels SP1, SP2, SP3.

[0079] The upper electrode 175 provided on the intermediate layer 173 may be formed over the entire surface of the substrate 110 through a common mask. For example, the upper electrode 175 may be made of a transparent conductive material such as indium tin oxide (ITO) or indium zinc oxide (IZO), or may be made of silver (Ag), aluminum (Al), magnesium (Mg), calcium (Ca), or an alloy thereof and may be formed thin enough to transmit light.

[0080] An encapsulation layer 180 may be provided on the upper electrode 175 to cover the entire active area and non-active area of the substrate 110. The encapsulation layer 180 prevents oxygen and moisture from entering the light-emitting device 170a, thereby increasing the lifespan of the light-emitting display device. In one example, the encapsulation layer 180 may be formed in a structure in which one or more pairs of inorganic encapsulation films and organic encapsulation films are stacked.

[0081] Refer to Figure 4A, the display device of the present disclosure may include: a first insulating layer 220 disposed on the encapsulation layer 180, lenses 240 respectively corresponding to a plurality of light-emitting devices 170a and disposed on the first insulating layer 220, a first light-shielding pattern 210 respectively corresponding to the plurality of light-emitting devices 170a and disposed between the substrate 110 and the first insulating layer 220, and a second light-shielding pattern 230 disposed on the first insulating layer 220 and overlapping with the first light-shielding pattern 210. In the display device of the present disclosure, with respect to the central portion of the second light-shielding pattern 230, an edge portion of the second light-shielding pattern 230 around the central portion may have a first angle θ1.

[0082] The first insulating layer 220 may be disposed over the entire area of the encapsulation layer 180. The first insulating layer 220 according to the first embodiment may include a convex area CVA formed corresponding to a non-opening area NOA on the substrate 110. The convex area CVA may be formed along the edge of the lens 240 within the non-opening area NOA. The convex area CVA may be a portion protruding with respect to a flat area FA in a direction away from the substrate 110. A portion of the first insulating layer 220 other than the convex area CVA may be the flat area FA. In this case, the first insulating layer 220 may be formed to include the flat area FA and the convex area CVA by a process using a half-tone mask.

[0083] The convex area CVA of the first insulating layer 220 may be formed along the edge of each lens 240. In some cases, the edge of the convex area CVA of the first insulating layer 220 may partially overlap with the edge of each lens 240. That is to say, the convex area CVA of the first insulating layer 220 may be disposed along the edge of the opening area OA. The convex area CVA of the first insulating layer 220 may include an upper surface 220a parallel to the flat area FA and a side surface 220b inclined from the upper surface 220a toward the substrate 110. In the convex area CVA of the first insulating layer 220, a first angle θ1 formed between the upper surface 220a and the side surface 220b may be greater than or equal to 90° and less than 180°. A second angle θ2 formed by the side surface 220b of the convex area CVA with respect to the substrate 110 may be an acute angle. Here, if according to the process using a half-tone mask, a vertical spacing distance between the surface of the flat area FA and the upper surface 220a of the convex area CVA is about 3 μm, the second angle θ2 formed by the side surface 220b of the convex area CVA with respect to the substrate 110 may be about 70°. The second light-shielding pattern 230 may be disposed on the convex area CVA of the first insulating layer 220, and the first light-shielding pattern 210 may be disposed below the convex area CVA of the first insulating layer 220. The convex area CVA may bend the second light-shielding pattern 230.

[0084] The flat area FA of the first insulating layer 220 may be a portion of the first insulating layer 220 other than the convex area CVA. The flat area FA may be connected to the side surface 220b of the convex area CVA, and the lenses 240 may be provided on the flat area FA corresponding to a plurality of light-emitting devices 170a, respectively. In other words, the lenses 240 may be provided on the flat area FA of the first insulating layer 220 that overlaps each opening area OA. The lenses 240 may extend beyond the flat area FA of the first insulating layer 220 to overlap a part of the convex area CVA outside the flat area FA.

[0085] The first light-shielding pattern 210 and the second light-shielding pattern 230 may be arranged such that the convex area CVA of the first insulating layer 220 is sandwiched between the first light-shielding pattern 210 and the second light-shielding pattern 230. The first light-shielding pattern 210 and the second light-shielding pattern 230 may be made of different materials. In addition, the first light-shielding pattern 210 and the second light-shielding pattern 230 may have different reflectivities. The first light-shielding pattern 210 and the second light-shielding pattern 230 may have different widths, and either the first light-shielding pattern 210 or the second light-shielding pattern 230 may be formed such that its edge portion is inclined with respect to its central portion. In the display device according to the first embodiment, the second width W2 of the second light-shielding pattern 230 may be greater than the first width W1 of the first light-shielding pattern 210, and the second light-shielding pattern 230 may be formed such that its edge portion is inclined with respect to its central portion.

[0086] The first light-shielding pattern 210 may be provided on the area of the encapsulation layer 180 other than the area corresponding to each opening area OA. The first light-shielding pattern 210 may overlap the upper surface 220a of the convex area CVA between the first insulating layer 220 and the flat area FA. In addition, the first light-shielding pattern 210 may expose at least a portion of the second light-shielding pattern 230 that overlaps the side surface 220b of the first insulating layer 220 to the substrate 110. In addition, considering the incident angle of light from the light-emitting device, the first light-shielding pattern 210 may also expose a portion of the second light-shielding pattern 230 that overlaps the edge connecting the upper surface 220a and the side surface 220b of the first insulating layer 220 to the substrate 110. In other words, the first light-shielding pattern 210 may partially overlap the upper surface 220a of the first insulating layer 220.

[0087] The first light-shielding pattern 210 may include a light-absorbing material. For example, the first light-shielding pattern 210 may include a black dye. The first light-shielding pattern 210 may prevent optical interference and light leakage between adjacent sub-pixels. Although the first light-shielding pattern 210 includes a light-absorbing material, it may have a certain amount of reflectivity. The first light-shielding pattern 210 including a general light-absorbing material may have a reflectivity of about 4.6%.

[0088] The second light-shielding pattern 230 may be disposed on the convex region CVA of the first insulating layer 220. That is to say, the second light-shielding pattern 230 may be disposed along the edge of each lens 240. The second light-shielding pattern 230 may be formed in a shape corresponding to the shape of the upper surface 220a and the side surface 220b of the convex region CVA of the first insulating layer 220. The second light-shielding pattern 230 may be divided into a central portion in contact with the upper surface 220a of the convex region CVA of the first insulating layer 220 and an edge portion in contact with the side surface 220b of the convex region CVA of the first insulating layer 220, and according to the shape of the convex region CVA of the first insulating layer 220, the edge portion of the second light-shielding pattern 230 may be inclined with respect to its central portion. In other words, the edge portion of the second light-shielding pattern 230 may form a first angle θ1 with its central portion. Herein, according to the shape of the convex region CVA of the first insulating layer 220, the first angle θ1 may be greater than or equal to 90° and less than 180°. In addition, the central portion of the second light-shielding pattern 230 in contact with the upper surface 220a of the convex region CVA of the first insulating layer 220 may overlap with the first light-shielding pattern 210, and the edge portion of the second light-shielding pattern 230 in contact with the side surface 220b of the convex region CVA of the first insulating layer 220 may be exposed from the first light-shielding pattern 210 to the substrate 110. Therefore, the light emitted from the light-emitting device 170a and propagating to the region between the lenses 240 may enter the portion of the second light-shielding pattern 230 exposed from the first light-shielding pattern 210. The incident light may be reflected by the inclined edge portion of the second light-shielding pattern 230 to the region between the first light-shielding pattern 210 and the second light-shielding pattern 230. In addition, the incident light may be reflected by the inclined edge portion of the second light-shielding pattern 230 at an acute angle and then may be re-reflected by the metal component of the light-emitting device 170a. The re-reflected light may propagate to a region away from the lens adjacent to the light-emitting device 170a and thus is less likely to reach the lens not corresponding to the light-emitting device 170a. Therefore, among the light emitted from the light-emitting device 170a and propagating to the region between the lenses 240, the amount of light reaching the lens not corresponding to the light-emitting device 170a may be greatly reduced.

[0089] The second light-shielding pattern 230 may be made of metal. For example, the second light-shielding pattern 230 may be a touch electrode. In this case, the second light-shielding pattern 230 may include a plurality of transmitting electrodes and a plurality of receiving electrodes intersecting each other, and may detect a touch from a capacitance change between the plurality of transmitting electrodes and the plurality of receiving electrodes. Refer to Figure 2 , when the second light-shielding pattern 230 shown is a touch electrode, each second light-shielding pattern 230 may be one of the transmitting electrode and the receiving electrode, and may further include a connection electrode electrically connecting the transmitting electrode and the receiving electrode to each other. The second light-shielding pattern 230 made of a common metal material may have a reflectivity of about 50%.

[0090] Reference Figure 4B As shown in, the light emitted from the light-emitting device 170a on the substrate 110 can pass through the opening region OA, and a part of the light can propagate to the non-opening region NOA. The light emitted from the light-emitting device 170a and propagating to the non-opening region NOA can reach the first light-shielding pattern 210 and the second light-shielding pattern 230 between the lenses 240. Referring to Figure 4B LE11, LE12, and LE13 in, the light LE11 emitted from the light-emitting device 170a and reaching the first light-shielding pattern 210 can be partially absorbed in the first light-shielding pattern 210, and the remaining part of the light LE11 can be reflected (LE12) to the light-emitting array 100 provided with the light-emitting device 170a. Then, the reflected light LE12 can be re-reflected (LE13) by a component such as a lower electrode or an upper electrode of the light-emitting device 170a to another lens that does not correspond to the light-emitting device 170a. In this way, a part of the light reaching the first light-shielding pattern 210 having a planar shape can be propagated to another lens that does not correspond to the light-emitting device 170a through reflection and re-reflection. Therefore, light leakage may occur. However, according to the present disclosure, the first light-shielding pattern 210 is formed to have a width smaller than that of the second light-shielding pattern 230, and the relatively narrow first light-shielding pattern 210 is provided between the lenses 240. In this way, the width of the planar reflection element can be minimized.

[0091] In addition, referring to Figure 4B As shown in, due to the second light-shielding pattern 230 including a central portion and an edge portion inclined with respect to the central portion, the present disclosure can greatly reduce the reflection and re-reflection of the light emitted from the light-emitting device 170a toward another lens that does not correspond to the light-emitting device 170a. For example, the light LE21 emitted from the light-emitting device 170a and reaching the portion of the second light-shielding pattern 230 exposed from the first light-shielding pattern 210 can be partially absorbed in the second light-shielding pattern 230, and the remaining part of the light LE21 can be reflected from the second light-shielding pattern 230. In this case, due to the inclined shape of the second light-shielding pattern 230, the light can be reflected to the first light-shielding pattern 210, and can experience repeated re-reflection and absorption (LE22) between the first light-shielding pattern 210 and the second light-shielding pattern 230. In this way, the light LE21 reaching the portion of the second light-shielding pattern 230 in contact with the side surface 220b of the convex region CVA of the first insulating layer 220 can be trapped between the first light-shielding pattern 210 and the second light-shielding pattern 230. Therefore, light propagation to another lens that does not correspond to the light-emitting device 170a can be prevented, thereby preventing light leakage.

[0092] A planarization layer 250 may be provided on a first insulating layer 220 on which a second light-shielding pattern 230 and a lens 240 are provided. The planarization layer 250 may provide a substantially flat surface on the surface of the first insulating layer 220 and on the uneven surfaces of the second light-shielding pattern 230 and the lens 240 provided on the first insulating layer 220. For example, the planarization layer 250 may be made of an organic insulating material.

[0094] Referring to Figure 5 , a third light-shielding pattern may be provided on the second light-shielding pattern 230, or a third light-shielding pattern may be provided on the first light-shielding pattern 210, or a third light-shielding pattern may be provided on both the second light-shielding pattern 230 and the first light-shielding pattern 210.

[0095] Referring to Figure 5 of (a), a third light-shielding pattern 231a may be provided on the second light-shielding pattern 230. The third light-shielding pattern 231a may cover the entire area of the upper surface of the second light-shielding pattern 230. In this case, the edge of the third light-shielding pattern 231a may be covered by the lens 240. The third light-shielding pattern 231a may include the same material as the first light-shielding pattern 210.

[0096] Referring to Figure 5 of (b), a third light-shielding pattern 231b may be provided on a part of the second light-shielding pattern 230. In this case, the side surface of the third light-shielding pattern 231b may be in contact with the lens 240. The third light-shielding pattern 231b may include the same material as the first light-shielding pattern 210.

[0097] Referring to Figure 5 of (c), a third light-shielding pattern 231a may be provided on the second light-shielding pattern 230, and a fourth light-shielding pattern 231c may be provided on the first light-shielding pattern 210. The third light-shielding pattern 231a may cover the entire area of the upper surface of the second light-shielding pattern 230 and may include the same material as the first light-shielding pattern 210. The fourth light-shielding pattern 231c may be provided on a part of the first light-shielding pattern 210 and may include metal. When the first light-shielding pattern 210 is a touch electrode, the fourth light-shielding pattern 231c may be a connection electrode for interconnecting a plurality of first light-shielding patterns 210. In this case, the fourth light-shielding pattern 231c may be electrically connected to the first light-shielding pattern 210.

[0098] Figure 6 is a cross-sectional view of the second embodiment taken along line II-II’ in Figure 2 . Hereinafter, descriptions of the same structures as those of the first embodiment will be omitted.

[0099] Reference Figure 6 Referring to Figure 6 , the first insulating layer 320 according to the second embodiment may include a concave region CCA formed corresponding to the non-opening region NOA. The concave region CCA may be formed along the edge of the lens 340. The concave region CCA may be a portion that is recessed with respect to the flat region FA toward the substrate 110. The portion of the first insulating layer 320 other than the concave region CCA may be the flat region FA.

[0100] The concave region CCA of the first insulating layer 320 may partially overlap with the edge of each lens 340. The concave region CCA may include a bottom surface 320a parallel to the flat region FA, and a side surface 320b formed between the bottom surface 320a and the surface of the adjacent flat region FA. A first angle θ1 may be formed between the bottom surface 320a and the side surface 320b of the concave region CCA. The first angle θ1 may be greater than or equal to 90° and less than 180°. In addition, the side surface 320b of the concave region CCA may form a second angle θ2 with respect to the substrate 110. The second angle θ2 may be an acute angle. The second light-shielding pattern 330 may be disposed on the concave region CCA of the first insulating layer 320, and the first light-shielding pattern 310 may be disposed below the concave region CCA of the first insulating layer 320. The concave region CCA may bend the second light-shielding pattern 330.

[0101] The first light-shielding pattern 310 and the second light-shielding pattern 330 may be disposed such that each concave region CCA of the first insulating layer 320 is sandwiched between the first light-shielding pattern 310 and the second light-shielding pattern 330. The first light-shielding pattern 310 and the second light-shielding pattern 330 may be made of different materials. In addition, the first light-shielding pattern 310 and the second light-shielding pattern 330 may have different reflectivities. The first light-shielding pattern 310 and the second light-shielding pattern 330 may have different widths, and either the first light-shielding pattern 310 or the second light-shielding pattern 330 may be formed such that its edge portion is inclined with respect to its central portion. In the display device according to the second embodiment, the second width W2 of the second light-shielding pattern 330 may be greater than the first width W1 of the first light-shielding pattern 310, and the edge portion of the second light-shielding pattern 330 having a relatively large width may be formed to be inclined.

[0102] The first light-shielding pattern 310 may be disposed on the region of the encapsulation layer 180 other than the region corresponding to each opening region OA. The first light-shielding pattern 310 may overlap with the bottom surface 320a of the concave region CCA between the first insulating layer 320 and the flat region FA. That is, the first light-shielding pattern 310 may expose at least the portion of the second light-shielding pattern 330 that overlaps with the side surface 320b of the first insulating layer 320 to the substrate 110.

[0103] The second light-shielding pattern 330 may be disposed on the recessed area CCA of the first insulating layer 320. That is to say, the second light-shielding pattern 330 may be disposed along the edge of each lens 340. The second light-shielding pattern 330 may be formed in a shape corresponding to the shapes of the bottom surface 320a and the side surface 320b of the recessed area CCA of the first insulating layer 320. The second light-shielding pattern 330 may be divided into a central portion in contact with the bottom surface 320a of the recessed area CCA of the first insulating layer 320 and an edge portion in contact with the side surface 320b of the recessed area CCA of the first insulating layer 320, and according to the shape of the recessed area CCA of the first insulating layer 320, the edge portion of the second light-shielding pattern 330 may be inclined with respect to its central portion. In other words, the edge portion of the second light-shielding pattern 330 may be inclined with respect to the substrate 110 at a predetermined angle, that is, the second angle θ2 defined by the recessed area CCA of the first insulating layer 320. In addition, the central portion of the second light-shielding pattern 330 in contact with the bottom surface 320a of the recessed area CCA of the first insulating layer 320 may overlap with the first light-shielding pattern 310. In other words, the edge portion of the second light-shielding pattern 330 in contact with the side surface 320b of the recessed area CCA of the first insulating layer 320 may be exposed from the first light-shielding pattern 310 to the substrate 110. Therefore, the light emitted from the light-emitting device 170a and propagating to the area between the lenses 340 may enter the portion of the second light-shielding pattern 330 exposed from the first light-shielding pattern 310, and the entered light may be reflected by the inclined edge portion of the second light-shielding pattern 330 at an acute angle. Therefore, the amount of light reaching another lens not corresponding to the light-emitting device 170a due to the re-reflection of the components of the light-emitting device 170a may be reduced.

[0106] Referring to Figure 7 of (a), a third light-shielding pattern 331a may be disposed on the second light-shielding pattern 330. The third light-shielding pattern 331a may cover the entire area of the upper surface of the second light-shielding pattern 330. In this case, the edge of the third light-shielding pattern 331a may be covered by the lens 340. The third light-shielding pattern 331a may include the same material as the first light-shielding pattern 310.

[0107] Referring to Figure 7In (b) of [description], a third light-shielding pattern 331b may be provided on a part of the second light-shielding pattern 330. In this case, a side surface of the third light-shielding pattern 331b may be in contact with the lens 340. The third light-shielding pattern 331b may include the same material as the first light-shielding pattern 310.

The third light-shielding pattern 331a may cover the entire area of the upper surface of the second light-shielding pattern 330 and may include the same material as the first light-shielding pattern 310. The fourth light-shielding pattern 331c may be provided on a part of the first light-shielding pattern 310 and may include metal. When the first light-shielding pattern 310 is a touch electrode, the fourth light-shielding pattern 331c may be a connection electrode that interconnects a plurality of first light-shielding patterns 310. In this case, the fourth light-shielding pattern 331c may be electrically connected to the first light-shielding pattern 310.

[0109] Figure 8 is a plan view of a display device according to the third and fourth embodiments of the present disclosure. In Figure 8 since the plan views of the third embodiment and the fourth embodiment are the same as each other, the reference numerals of the third embodiment are representatively used. Figure 9 is a cross-sectional view of the third embodiment taken along the line III-III' in Figure 8 and Figure 10 is a cross-sectional view of the fourth embodiment taken along the line III-III' in Figure 8 .

[0110] Referring to Figure 8 , a display device according to the third embodiment of the present disclosure may include a first light-shielding pattern 410 and a second light-shielding pattern 430 provided in a non-opening area NOA. The first light-shielding pattern 410 and the second light-shielding pattern 430 may have different widths. In the third embodiment, a first width W1 of the first light-shielding pattern 410 may be greater than a second width W2 of the second light-shielding pattern 430.

[0111] In the third embodiment, the first light-shielding pattern 410 may overlap a part of an edge of the lens 440 while at least exposing an opening area OA that overlaps the lens 440. The first light-shielding pattern 410 may be provided on an area of the substrate 110 other than the opening area.

[0112] The second light-shielding pattern 430 may be separated from the edge of the lens 440 to expose the lens 440. The second light-shielding pattern 430 may be patterned on the substrate 110 so as to be provided as a plurality. The plurality of second light-shielding patterns 430 may be connected to each other via a connection pattern provided therebetween.

[0113] Figure 9 is taken along Figure 8 the line III-III' in the cross-sectional view of the third embodiment.

[0114] Referring to Figure 9 , in the third embodiment of the present disclosure, a second insulating layer 423 may be provided between the encapsulation layer 180 and the first insulating layer 421. In addition, the first light-shielding pattern 410 according to the third embodiment may be provided between the first insulating layer 421 and the second insulating layer 423. Therefore, in the third embodiment of the present disclosure, the second insulating layer 423 can bend the first light-shielding pattern 410.

[0115] The first insulating layer 421 and the second insulating layer 423 may be provided over the entire area of the encapsulation layer 180. The second insulating layer 423 according to the third embodiment may include a convex area CVA formed corresponding to the non-opening area NOA on the substrate 110. The convex area CVA may be formed along the edge of the lens 440 within the non-opening area NOA. The convex area CVA may be a portion protruding in a direction away from the substrate 110 with respect to the flat area FA. The portion of the second insulating layer 423 other than the convex area CVA may be the flat area FA.

[0116] The convex area CVA of the second insulating layer 423 may be formed along the edge of each lens 440. In some cases, the edge of the convex area CVA of the second insulating layer 423 may partially overlap the edge of each lens 440. The convex area CVA of the second insulating layer 423 may include an upper surface 423a parallel to the flat area FA and a side surface 423b inclined from the upper surface 423a toward the substrate 110. In the convex area CVA, a first angle θ1 formed between the upper surface 423a and the side surface 423b may be greater than or equal to 90° and less than 180°. The second angle θ2 formed by the side surface 423b of the convex area CVA with respect to the substrate 110 may be an acute angle. The first light-shielding pattern 410 may be provided on the convex area CVA of the second insulating layer 423.

[0117] The first insulating layer 421 may be provided on the second insulating layer 423 and the first light-shielding pattern 410. The lens 440 may be provided in the area of the first insulating layer 421 that overlaps with the flat area FA of the second insulating layer 423, and the second light-shielding pattern 430 may be provided in the area of the first insulating layer 421 that overlaps with the convex area CVA of the second insulating layer 423. The lens 440 may extend beyond the flat area FA of the second insulating layer 423 to overlap with a part of the convex area CVA outside the flat area FA.

[0118] The first light shielding pattern 410 and the second light shielding pattern 430 may be disposed on the raised area CVA with the first insulating layer 421 interposed therebetween. The first light shielding pattern 410 and the second light shielding pattern 430 may be made of different materials. In addition, the first light shielding pattern 410 and the second light shielding pattern 430 may have different reflectivities. In the display device according to the third embodiment, the first width W1 of the first light shielding pattern 410 may be greater than the second width W2 of the second light shielding pattern 430, and the edge portion of the first light shielding pattern 410 having a relatively large width may be formed to be inclined.

[0119] The first light shielding pattern 410 may be disposed on the convex area CVA of the second insulating layer 423. That is, the first light shielding pattern 410 may be disposed along the edge of each lens 440. The first light shielding pattern 410 may be formed in a shape corresponding to the shape of the upper surface 423a and the side surface 423b of the convex area CVA of the second insulating layer 423. The first light shielding pattern 410 may be divided into a central portion in contact with the upper surface 423a of the convex area CVA of the second insulating layer 423 and an edge portion in contact with the side surface 423b of the convex area CVA of the second insulating layer 423, and the edge portion of the first light shielding pattern 410 may be inclined relative to the central portion thereof according to the shape of the convex area CVA of the second insulating layer 423. In other words, the edge portion of the first light shielding pattern 410 may be inclined relative to the substrate 110 at a predetermined angle, that is, the second angle θ2 defined by the convex area CVA of the second insulating layer 423. In addition, a central portion of the first light-shielding pattern 410 in contact with the upper surface 423a of the raised area CVA of the second insulating layer 423 may overlap with the second light-shielding pattern 430, and an edge portion of the first light-shielding pattern 410 in contact with the side surface 423b of the raised area CVA of the second insulating layer 423 may be exposed from the second light-shielding pattern 430 to the side opposite to the substrate 110. Therefore, light emitted from the light-emitting device 170a and propagating to the area between the lenses 440 may be reflected at an acute angle by the inclined edge portion of the first light-shielding pattern 410. Therefore, the amount of light reaching another lens that does not correspond to the light-emitting device 170a due to re-reflection by the reflective component of the light-emitting device 170a may be reduced. Here, the reflective component of the light-emitting device 170a may include a lower electrode ( Figure 3 171a) and the upper electrode ( Figure 3 175).

[0120] The second light-shielding pattern 430 may be disposed on the first insulating layer 421. The second light-shielding pattern 430 may overlap the upper surface 423a of the convex area CVA between the flat areas FA of the second insulating layer 423. Since the second light-shielding pattern 430 is made of metal, the second light-shielding pattern 430 disposed between the lenses 440 may be formed to have as small a width as possible so as to minimize the interference between the metals. However, the second light-shielding pattern 430 according to the third embodiment of the present disclosure is not limited thereto. In some cases, the second light-shielding pattern 430 may overlap the adjacent lenses 440.

[0121] Figure 10 is a cross-sectional view of the fourth embodiment taken along line III-III' in Figure 8 .

[0122] Referring to Figure 10 , the second insulating layer 523 according to the fourth embodiment may include a concave area CCA formed corresponding to the non-opening area NOA. The concave area CCA may be formed along the edge of the lens 540. The concave area CCA may be a portion that is recessed with respect to the flat area FA toward the substrate 110. The portion of the second insulating layer 523 other than the concave area CCA may be the flat area FA.

[0123] The concave area CCA of the second insulating layer 523 may partially overlap the edge of each lens 540. The concave area CCA may include a bottom surface 523a parallel to the flat area FA and a side surface 523b formed between the bottom surface 523a and the surface of the adjacent flat area FA. A first angle θ1 may be formed between the bottom surface 523a and the side surface 523b of the concave area CCA. The first angle θ1 may be greater than or equal to 90° and less than 180°. The side surface 523b of the concave area CCA may form a second angle θ2 with respect to the substrate 110. The second angle θ2 of the side surface 523b of the concave area CCA may be an acute angle. The first light-shielding pattern 510 may be disposed on the concave area CCA of the second insulating layer 523. The concave area CCA may bend the first light-shielding pattern 510.

[0124] The first light-shielding pattern 510 and the second light-shielding pattern 530 may be disposed on each concave area CCA with the first insulating layer 521 interposed therebetween. The first light-shielding pattern 510 and the second light-shielding pattern 530 may be made of different materials. In addition, the first light-shielding pattern 510 and the second light-shielding pattern 530 may have different reflectivities. In the display device according to the fourth embodiment, a first width W1 of the first light-shielding pattern 510 may be greater than a second width W2 of the second light-shielding pattern 530, and an edge portion of the first light-shielding pattern 510 having a relatively large width may be formed to be inclined.

[0125] The first light-shielding pattern 510 may be disposed on the recessed area CCA of the second insulating layer 523. That is to say, the first light-shielding pattern 510 may be disposed along the edge of each lens 540. In addition, the first light-shielding pattern 510 may be disposed on the area of the second insulating layer 523 other than a predetermined area corresponding to the flat area FA. The first light-shielding pattern 510 may be formed in a shape corresponding to the shapes of the bottom surface 523a and the side surface 523b of the recessed area CCA of the second insulating layer 523. The first light-shielding pattern 510 may be divided into a central portion in contact with the bottom surface 523a of the recessed area CCA of the second insulating layer 523 and an edge portion in contact with the side surface 523b of the recessed area CCA of the second insulating layer 523, and according to the shape of the recessed area CCA of the second insulating layer 523, the edge portion of the first light-shielding pattern 510 may be inclined with respect to its central portion. In other words, the edge portion of the first light-shielding pattern 510 may be inclined with respect to the substrate 110 at a predetermined angle, that is, the second angle θ2 defined by the recessed area CCA of the second insulating layer 523. In addition, the central portion of the first light-shielding pattern 510 in contact with the bottom surface 523a of the recessed area CCA of the second insulating layer 523 may overlap with the second light-shielding pattern 530, and the edge portion of the first light-shielding pattern 510 in contact with the side surface 523b of the recessed area CCA of the second insulating layer 523 may be exposed from the second light-shielding pattern 530 to the side opposite to the substrate 110. Therefore, the light emitted from the light-emitting device 170a and propagating to the area between the lenses 540 may be reflected by the inclined edge portion of the first light-shielding pattern 510 at an acute angle. Therefore, the amount of light reaching another lens not corresponding to the light-emitting device 170a due to the re-reflection of the reflection component of the light-emitting device 170a can be reduced.

[0126] The second light-shielding pattern 530 may be disposed on the first insulating layer 521. The second light-shielding pattern 530 may overlap with the bottom surface 523a of the recessed area CCA between the flat areas FA of the second insulating layer 523. Since the second light-shielding pattern 530 is made of metal, the second light-shielding pattern 530 disposed between the flat areas FA, that is, between the lenses 540, may be formed to have as small a width as possible in order to minimize the interference between the metals. However, the second light-shielding pattern 530 according to the fourth embodiment of the present disclosure is not limited thereto. In some cases, the second light-shielding pattern 530 may overlap with adjacent lenses 540.

[0128] Refer to Figure 11, a third light-shielding pattern 431a or 531a may be provided on the first light-shielding pattern 410 or 510. Although not shown, a separate light-shielding pattern including the same material as the first light-shielding pattern 410 or 510 may be provided on the second light-shielding pattern 430 or 530.

[0129] Referring to Figure 11 of (a), a third light-shielding pattern 431a may be provided on the first light-shielding pattern 410. The third light-shielding pattern 431a may be provided on a part of the first light-shielding pattern 410 and may include a metal. When the first light-shielding pattern 410 is a touch electrode, the third light-shielding pattern 431a may be a connection electrode interconnecting a plurality of first light-shielding patterns 410. In this case, the third light-shielding pattern 431a may be electrically connected to the first light-shielding pattern 410.

[0130] Referring to Figure 11 of (b), a third light-shielding pattern 531a may be provided on the first light-shielding pattern 510. The third light-shielding pattern 531a may be provided on a part of the first light-shielding pattern 510 and may include a metal. When the first light-shielding pattern 510 is a touch electrode, the third light-shielding pattern 531a may be a connection electrode interconnecting a plurality of first light-shielding patterns 510. In this case, the third light-shielding pattern 531a may be electrically connected to the first light-shielding pattern 510.

[0131] Figure 12 is a cross-sectional view of a display device according to a fifth embodiment of the present disclosure.

[0132] In a display device according to a fifth embodiment of the present disclosure, a first light-shielding pattern 611 corresponding to a non-opening area NOA may be provided on a package layer 180, a first insulating layer 620 may be provided on the first light-shielding pattern 611 over the entire substrate 110, a second light-shielding pattern 630 and a third light-shielding pattern 613 may be provided on a convex area CVA of the first insulating layer 620, and a lens 640 may be provided on a flat area FA of the first insulating layer 620 overlapping with an opening area OA.

[0133] The first insulating layer 620 may be provided over the entire area of the package layer 180. The first insulating layer 620 according to the fifth embodiment may include a convex area CVA formed corresponding to the non-opening area NOA on the substrate 110. The convex area CVA may be formed along the edge of the lens 640 within the non-opening area NOA. A portion of the first insulating layer 620 other than the convex area CVA may be a flat area FA.

[0134] The convex region CVA of the first insulating layer 620 may be formed along the edge of each lens 640. The convex region CVA of the first insulating layer 620 may be disposed along the edge of the opening region OA. The convex region CVA of the first insulating layer 620 may include an upper surface 620a parallel to the flat region FA and a side surface 620b inclined from the upper surface 620a toward the substrate 110. In the convex region CVA, a first angle θ1 formed between the upper surface 620a and the side surface 620b may be greater than or equal to 90° and less than 180°. The second angle θ2 formed by the side surface 620b of the convex region CVA with respect to the substrate 110 may be an acute angle. The second light-shielding pattern 630 and the third light-shielding pattern 613 may be sequentially disposed on the convex region CVA of the first insulating layer 620, and the first light-shielding pattern 611 may be disposed below the convex region CVA of the first insulating layer 620. In this case, the convex region CVA may bend the third light-shielding pattern 613.

[0135] The flat region FA of the first insulating layer 620 may be the portion of the first insulating layer 620 other than the convex region CVA. The lens 640 may be disposed on the flat region FA of the first insulating layer 620 corresponding to the opening region OA. The planarization layer 650 may be in contact with the portion of the upper surface of the first insulating layer 620 where the lens 640, the second light-shielding pattern 630, and the third light-shielding pattern 613 are not provided.

[0136] The lens 640 may be disposed on the flat region FA of the first insulating layer 620 overlapping the opening region OA. The lens 640 may extend beyond the flat region FA of the first insulating layer 620 to partially overlap with the convex region CVA outside the flat region FA.

[0137] The first light-shielding pattern 611 and the second light-shielding pattern 630 may be arranged such that the convex area CVA of the first insulating layer 620 is sandwiched between the first light-shielding pattern 611 and the second light-shielding pattern 630. In addition, the third light-shielding pattern 613 may be disposed on the convex area CVA while covering the second light-shielding pattern 630. The first light-shielding pattern 611 and the third light-shielding pattern 613 may include the same material or may have similar reflectivities. In addition, each of the first light-shielding pattern 611, the third light-shielding pattern 613, and the second light-shielding pattern 630 may be made of a different material. In addition, each of the first light-shielding pattern 611, the third light-shielding pattern 613, and the second light-shielding pattern 630 may have a different reflectivity. In the display device according to the fifth embodiment, the first light-shielding pattern 611, the second light-shielding pattern 630, and the third light-shielding pattern 613 may have different first width W1, second width W, and third width W3 from each other, and any one of the first light-shielding pattern 611, the second light-shielding pattern 630, and the third light-shielding pattern 613 may be formed such that its edge portion is inclined with respect to its central portion. Specifically, the first width W1 of the first light-shielding pattern 611 and the second width W2 of the second light-shielding pattern 630 may be smaller than the third width W3 of the third light-shielding pattern 613. Since the second light-shielding pattern 630 is made of metal, the second light-shielding pattern 630 disposed between the lenses 640 may be formed to have as small a width as possible in order to minimize the interference between the metals. Therefore, the second light-shielding pattern 630 may have a width smaller than that of the first light-shielding pattern 611. In addition, the edge portion of the third light-shielding pattern 613 may be formed to be inclined.

[0138] The first light-shielding pattern 611 may be disposed on a region of the encapsulation layer 180 other than a predetermined region corresponding to each opening area OA. The first light-shielding pattern 611 may overlap the upper surface 620a of the convex area CVA between the first insulating layer 620 and the flat area FA. In addition, the first light-shielding pattern 611 may expose at least a portion of the third light-shielding pattern 613 that overlaps the side surface 620b of the first insulating layer 620 to the substrate 110.

[0139] The second light-shielding pattern 630 may be disposed on the convex area CVA of the first insulating layer 620. That is, the second light-shielding pattern 630 may be disposed along the edge of each lens 640. The second light-shielding pattern 630 may overlap the upper surface 620a of the convex area CVA between the first insulating layer 620 and the flat area FA. In addition, the second light-shielding pattern 630 may expose at least a portion of the third light-shielding pattern 613 that overlaps the side surface 620b of the first insulating layer 620 to the substrate 110.

[0140] The third light-shielding pattern 613 may be disposed on the convex region CVA of the first insulating layer 620. The third light-shielding pattern 613 may be disposed on the second light-shielding pattern 630 while covering the entire area of the second light-shielding pattern 630. The third light-shielding pattern 613 may be formed in a shape corresponding to the shapes of the upper surface 620a and the side surface 620b of the convex region CVA of the first insulating layer 620. The third light-shielding pattern 613 may be divided into a central portion in contact with the upper surface 620a of the convex region CVA of the first insulating layer 620 and an edge portion in contact with the side surface 620b of the convex region CVA of the first insulating layer 620, and according to the shape of the convex region CVA of the first insulating layer 620, the edge portion of the third light-shielding pattern 613 may be inclined with respect to its central portion. In other words, the edge portion of the third light-shielding pattern 613 may form a second angle θ2 with respect to the substrate 110, and the second angle θ2 is an acute angle. In addition, the central portion of the third light-shielding pattern 613 in contact with the upper surface 620a of the convex region CVA of the first insulating layer 620 may overlap with the first light-shielding pattern 611, and the edge portion of the third light-shielding pattern 613 in contact with the side surface 620b of the convex region CVA of the first insulating layer 620 may be exposed from the first light-shielding pattern 611 to the substrate 110. Therefore, the light emitted from the light-emitting device 170a and propagating into the region between the lenses 640 may enter the portion of the third light-shielding pattern 613 exposed from the first light-shielding pattern 611, and the entered light may be reflected by the inclined edge portion of the third light-shielding pattern 613 into the region between the first light-shielding pattern 611 and the second light-shielding pattern 630 or at an acute angle. Therefore, the amount of light reaching another lens not corresponding to the light-emitting device 170a due to the re-reflection of the reflection member of the light-emitting device 170a may be reduced.

[0141] Figures 13A to 13D is a graph showing the intensity of light based on the viewing angle in the display device according to the first to fourth embodiments of the present disclosure. Figure 13A Shows that in Figure 4A the display device according to the first embodiment shown in, the intensity of light based on the viewing angle, which is measured under the conditions that the line width of the first light-shielding pattern 210 is 5 μm, the line width of the second light-shielding pattern 230 is 11 μm, the length of the edge portion of the second light-shielding pattern 230 is 3 μm, and the second angle θ2 is 70°. Figure 13B Shows that in Figure 6 the display device according to the second embodiment shown in, the intensity of light based on the viewing angle, which is measured under the conditions that the line width of the first light-shielding pattern 310 is 5 μm, the line width of the second light-shielding pattern 330 is 11 μm, the length of the edge portion of the second light-shielding pattern 330 is 3 μm, and the second angle θ2 is 70°. Figure 13C Shows that in Figure 9In the display device according to the third embodiment shown in the figure, the intensity of light based on the viewing angle is measured under the conditions that the line width of the first light-shielding pattern 410 is 12.6 μm, the line width of the second light-shielding pattern 430 is 11 μm, the length of the edge portion of the first light-shielding pattern 410 is 3 μm, and the second angle θ2 is 70°. Figure 13D shows the Figure 10 In the display device according to the fourth embodiment shown in the figure, the intensity of light based on the viewing angle is measured under the conditions that the line width of the first light-shielding pattern 510 is 12.6 μm, the line width of the second light-shielding pattern 530 is 11 μm, the length of the edge portion of the first light-shielding pattern 510 is 3 μm, and the second angle θ2 is 70°. In each graph, the horizontal axis represents the viewing angle (°), the vertical axis represents the intensity of light (%), and the intensity of light (%) is 100% when the viewing angle is 0°.

[0142] The following Table 1 shows the Figures 13A to 13D peak value shown in the figure. In the following Table 1, "2 nd peak" represents the second largest peak, and "high-angle peak" represents the largest peak at a viewing angle of 60° or more. "Conventional structure" in the following Table 1 represents a display device in which the first light-shielding pattern and the second light-shielding pattern have a flat shape without an inclined portion and overlap each other, the line width of the first light-shielding pattern is 12.6 μm, and the line width of the second light-shielding pattern is 11 μm.

[0143] [Table 1]

[0144] Conventional structure First embodiment Second embodiment Third embodiment Fourth embodiment <![CDATA[2 nd Peak (%)]]> 0.61 0.11 0.52 0.33 0.26 High angle peak (%) 0.01 0.07 0.09 0.02 0.02

[0145] Referring to [Table 1], the value of "2 nd peak" is the smallest in the first embodiment, and the value of "high-angle peak" is the smallest in the third and fourth embodiments. When the intensity of light is about 0.1%, the human eye can hardly perceive the light. Therefore, it can be seen from the value of the "high-angle peak" that almost no light leakage occurs in the first to fourth embodiments. In particular, it can be seen that in the display device according to the first embodiment in which the "2 nd peak" is 0.11 and the "high-angle peak" is 0.07, the amount of light leakage is the smallest. In addition, it can be seen that the value of the "2 nd peak" in the display devices according to the first to fourth embodiments of the present disclosure is smaller than the value of the "2 nd peak" (=0.61) in the conventional structure. Therefore, the display device of the present disclosure in which either the first light-shielding pattern or the second light-shielding pattern includes an inclined edge portion can improve the light-blocking effect of restricting the viewing angle by the lens and can reduce the light leakage phenomenon. In particular, compared with the conventional structure, in which the "2 ndThe display device according to the first embodiment of the present disclosure with a "peak" of 0.11 can reliably prevent light leakage and exhibits a greatly improved light-blocking effect.
