Description

[Technical field]

[0001] The present invention relates to a display device, and more particularly to a display device capable of preventing light leakage. [Background technology]

[0002] As we enter the information age, the field of display devices that visually display electrical information signals is rapidly developing. Accordingly, various display devices such as liquid crystal display devices (LCDs) and organic light emitting display devices (OLEDs) have been developed and applied to various fields.

[0003] Among them, a light emitting display device includes a light emitting element that is a self-emitting element, and does not require a separate light source used in a non-light emitting element, so that it can be made lighter and thinner. In addition, since the light emitting display device is a self-emitting type, there is no restriction on the viewing angle.

[0004] In this manner, the light emitting display device may include lenses corresponding to each of the plurality of light emitting elements in order to control the viewing angle for reasons such as application as a private life protection, information protection, and a display device for a vehicle.

[0005] Here, light emitted from the light emitting element can travel in all directions, not just through the lens. Here, the light emitted from the light emitting element and travelling between the lenses is reflected by a light blocking structure such as a blocking pattern provided between the lenses, and is re-reflected by a reflective component on the light emitting element side, reaching other lenses instead of the lens, resulting in light leakage. This may also cause a problem of reducing the cut-off effect in a display device for controlling the viewing angle. Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention is capable of solving the above-mentioned problems, and aims to provide a display device that prevents light from being reflected toward the light emitting element when it is reflected by a light-shielding structure provided in a non-opening portion, or adjusts the angle at which the light is reflected toward the light emitting element, so that even if it is re-reflected, it is not emitted toward another lens other than the lens in question. [Means for solving the problem]

[0007] The display device of the present invention can prevent light leakage by configuring an edge of one of the first and second light-shielding patterns capable of blocking light in the non-opening at an angle, thereby preventing light from the light-emitting element traveling to the non-opening from being reflected and re-reflected toward the light-emitting element, or preventing the light from being emitted to other lenses other than the lens in question even if it is re-reflected by the slanted edge.

[0008] According to one embodiment, a display device of the present invention includes a plurality of light-emitting elements positioned on a substrate, a first insulating layer provided on the plurality of light-emitting elements, lenses provided on the first insulating layer corresponding to each of the plurality of light-emitting elements, a first light-shielding pattern provided between the substrate and the first insulating layer corresponding to each space between the plurality of light-emitting elements, and a second light-shielding pattern provided on the first insulating layer overlapping the first light-shielding pattern, wherein the second light-shielding pattern includes a central portion and an edge portion surrounding the central portion, and the edge portion may be inclined with respect to the central portion.

[0009] According to another embodiment, a display device of the present invention may include a plurality of light-emitting elements positioned on a substrate, a first insulating layer provided on the plurality of light-emitting elements, a plurality of lenses provided on the first insulating layer corresponding to each of the plurality of light-emitting elements, a first light-shielding pattern provided between the substrate and the first insulating layer corresponding to spaces between the plurality of light-emitting elements, and a second light-shielding pattern provided on the first insulating layer overlapping the first light-shielding pattern, wherein the first light-shielding pattern may include a central portion and an edge portion surrounding the central portion, and the edge portion may be inclined with respect to the central portion.

[0010] According to another embodiment, a display device of the present invention may include a plurality of light-emitting elements positioned on a substrate, a first insulating layer provided on the plurality of light-emitting elements, a plurality of lenses positioned on the first insulating layer corresponding to each of the plurality of light-emitting elements, a first light-shielding pattern corresponding to an area located between the plurality of light-emitting elements between the substrate and the first insulating layer, a second light-shielding pattern overlapping the first light-shielding pattern on the first insulating layer, and a third light-shielding pattern covering the second light-shielding pattern on the first insulating layer, wherein the third light-shielding pattern may include a central portion and an edge portion surrounding the central portion, and the edge portion may be inclined with respect to the central portion. Effect of the Invention

[0011] The display device of the present invention has the following effects.

[0012] First, the display device of the present invention has an oblique edge of either one of the first and second light-shielding patterns capable of blocking light in the non-opening, thereby preventing light from the light-emitting element traveling to the non-opening from being reflected back toward the light-emitting element, or preventing light from being emitted to other lenses other than the lens in question even if it is reflected back by the oblique edge, thereby preventing light leakage.

[0013] Secondly, the display device of the present invention has an effect of preventing light leakage and improving the cut-off effect in a display device for controlling the viewing angle.

[0014] Third, the display device of the present invention has an effect of reducing production energy since light leakage can be prevented by simply providing an oblique edge of either the first light-shielding pattern or the second light-shielding pattern capable of blocking light in the non-opening portion. Therefore, the display device of the present invention has an effect of ESG (Environment / Social / Governance) in terms of environment and process optimization.

[0028] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred examples of a display device according to embodiments of the present specification will be described in detail with reference to the accompanying drawings.

[0029] 1a to 1c are plan views of a display device of the present invention.

[0030] 1a to 1c, the display device of the present invention may include a plurality of unit pixels including a first sub-pixel SP1, a second sub-pixel SP2, and a third sub-pixel SP3. Each of the first to third sub-pixels SP1, SP2, and SP3 may be a sub-pixel that emits light of a different color from each other. For example, each of the first to third sub-pixels SP1 to SP3 may be a sub-pixel that emits light of one of red, green, and blue.

[0031] The first to third subpixels SP1, SP2, and SP3 may have different area ratios. As a result, the first lower electrodes 171a and second lower electrodes 171b of the first to third subpixels SP1, SP2, and SP3 and the light-emitting portions and openings OA; OA1, OA2 of the first to third subpixels SP1, SP2, and SP3 may have different area ratios from the other subpixels. The areas of the first to third subpixels SP1, SP2, and SP3 may be determined in consideration of the life and light-emitting efficiency of the light-emitting element of the hue corresponding to each subpixel. That is, the subpixel emitting light of a short wavelength may have a larger area than the other subpixels, and the subpixel emitting light of a long wavelength may have a smaller area than the other subpixels. Thus, in the present invention, the area ratios of the subpixels emitting light of different hues are made different from each other, so that the life and light-emitting efficiency of the corresponding light-emitting elements can be made uniform. 1a to 1c, the second sub-pixel SP2 may have a larger area than the first and third sub-pixels SP1 and SP3, and the third sub-pixel SP3 may have a smaller area than the first and second sub-pixels SP1 and SP2. However, the present invention is not limited thereto, and the arrangement and area ratio of the first to third sub-pixels SP1, SP2, and SP3 may be different.

[0032] The first sub-pixels SP1 and the second sub-pixels SP2 may be alternately arranged in the second direction D2. The third sub-pixel SP3 may be arranged adjacent to the first sub-pixels SP1 and the second sub-pixels SP2 in the first direction D1 intersecting the second direction D2. Here, the first direction D1 and the second direction D2 may be directions that intersect perpendicularly with each other. However, the arrangement structure of the first to third sub-pixels SP1, SP2, and SP3 of the present invention is not limited thereto.

[0033] 1b and 1c, each of the first to third sub-pixels SP1, SP2, and SP3 may include a first bottom electrode 171a and a second bottom electrode 171b. The first bottom electrode 171a and the second bottom electrode 171b may be configured independently of each other and may be driven independently by different driving circuits. In some cases, the second bottom electrode 171b may include a plurality of second openings OA2. Here, a plurality of second bottom electrodes may be provided corresponding to the plurality of openings.

[0034] The first bottom electrode 171a and the second bottom electrode 171b may have different areas. In addition, the first bottom electrodes 171a of the first to third sub-pixels SP1, SP2, and SP3 may have different area ratios. Accordingly, the second bottom electrodes 171b of the first to third sub-pixels SP1, SP2, and SP3 may also have different area ratios.

[0035] The first lower electrode 171a may have a length in the first direction D1 longer than the length in the second direction D2. The first lower electrode 171a may include one first opening OA1. The second lower electrode 171b may also have a length in the first direction D1 longer than the length in the second direction D2. And, the second lower electrode 171b may include a plurality of second openings OA2. Meanwhile, the area excluding the first and second openings OA1 and OA2 may be defined as a non-opening.

[0036] The openings OA1 and OA2 may be regions from which emitted light is emitted. For example, the openings OA1 and OA2 may be regions exposed from a bank (115 in FIG. 3) provided between the light emitting elements (170a in FIG. 3). In other words, the openings OA1 and OA2 may be regions from which the light emitting elements 170a, in which a lower electrode and an upper electrode face each other with an intermediate layer therebetween, emit light. In the openings OA, the first opening OA corresponding to the first lower electrode 171a and the second openings OA2 corresponding to the second lower electrode 171b may have different areas.

[0037] A first opening OA1 corresponding to the first bottom electrode 171a may be provided in a first direction D1 of the first bottom electrode 171a. The length of the first opening OA1 in the first direction D1 may be longer than the length in the second direction D2.

[0038] The second openings OA2 corresponding to the second bottom electrode 171b may be arranged in the second bottom electrode 171b in a spaced-apart relationship in the first direction D1. Each of the second openings OA2 may have a length in the first direction D1 that is substantially the same as a length in the second direction D2.

[0039] A first lens L1 and a plurality of second lenses L2 may be provided corresponding to the first opening OA1 of the first bottom electrode 171a and the plurality of second openings OA2 of the second bottom electrode 171b, respectively. The first lens L1 and the plurality of second lenses L2 may have different shapes. Also, the first lens L1 and each of the second lenses L2 may have different area ratios on a plane.

[0040] The first lens L1 may have a length in the first direction D1 longer than the second direction D2 corresponding to the first opening OA1 of the first lower electrode 171a. The first lens L1 may be large enough to cover at least the entire first opening OA1 of the first lower electrode 171a. The first lens L1 may have an area larger than the first opening OA1 and may be provided on the first lower electrode 171a, exceeding at least the length of the first lower electrode 171a in the first direction D1. The first lens L1 may be a semi-cylindrical lens having a length in the first direction D1. More specifically, the first lens L1 may be an elliptical lens cut in the major axis direction.

[0041] The semi-cylindrical first lens L1 may have a rectangular cross section in a plane and a semicircular cross section when cut along a cutting line in the second direction D2. The semi-elliptical first lens L1 may have an elliptical cross section in a plane. Such a first lens L1 does not limit the viewing angle in the first direction D1, but can limit the viewing angle in the second direction D2.

[0042] Each of the second lenses L2 may be large enough to completely cover each of the second openings OA2 of the second bottom electrode 171b. Also, the length of each of the second lenses L2 in the first direction D1 may be shorter than the length of the first lens L1 in the first direction D1. The second lenses L2 may be hemispherical lenses.

[0043] The hemispherical second lens L2 may have a circular cross section on a plane and a semicircular cross section on a cross section cut along each of the cutting lines in the first direction D1 and the second direction D2. Such a hemispherical second lens L2 may limit the viewing angles in the first direction D1 and the second direction D2.

[0044] The display device of the present invention may be a viewing angle control display device that limits a viewing angle by including a semi-elliptical first lens L1 corresponding to the first bottom electrode 171a and a plurality of hemispherical second lenses L2 corresponding to the second bottom electrode 171b. The first lens L1 and the second lens L2 limit the viewing angle in different directions, so that the display device of the present invention can selectively realize a wide viewing angle and a narrow viewing angle.

[0045] FIG 2 is a plan view of a display device according to the first and second embodiments of the present invention. In FIG 2, since the plan views of the first and second embodiments are the same, the reference numerals of the first embodiment are representatively used. FIG 3 is a cross-sectional view of a light emitting array taken along line I-I' in FIG 2, and FIG 4a and FIG 4b are cross-sectional views taken along line II-II' in FIG 2 according to the first embodiment. Here, FIG 4b is a diagram showing the path of light emitted from any one light emitting element in the display device according to the present invention according to FIG 4a.

[0046] 2, the display device according to the first embodiment of the present invention may include a first light-shielding pattern 210 and a second light-shielding pattern 230 in the non-opening portion. The first light-shielding pattern 210 and the second light-shielding pattern 230 may have different widths. The second width (W2 in FIG. 4a) of the second light-shielding pattern 230 according to the first embodiment may be larger than the first width (W1 in FIG. 4a) of the first light-shielding pattern 210.

[0047] The first light blocking patterns 210 may be spaced apart from each edge of the lenses 240 and disposed on the entire surface of the substrate 110 to expose the lenses 240 .

[0048] The second light-shielding patterns 230 may expose at least the openings OA1 and OA2 of the lenses 240 and overlap a portion of each edge of the lenses 240. A plurality of such second light-shielding patterns 230 may be patterned and provided on the substrate 110. The plurality of second light-shielding patterns 230 may be connected to each other via a connection pattern.

[0049] 3 is a cross-sectional view of a light emitting array 100 provided on a substrate 110 of a display device according to the present invention. Referring to FIG. 3, the light emitting array 100 may include a structure provided between the substrate 110 and an encapsulation layer 180. A number of transistors TFTs, light emitting elements 170a respectively connected to the transistors TFTs, and an encapsulation layer 180 covering the light emitting elements 170a may be provided on the substrate 110. The light emitting elements 170a may overlap an opening OA.

[0050] The substrate 110 is divided into a display area where a screen is displayed and an outer area where a screen is not displayed, and the display area may be formed by repeatedly arranging a plurality of sub-pixels (SP1, SP2, SP3 in FIG. 1). The sub-pixels SP1, SP2, SP3 may each be formed of a light-emitting portion that actually emits light and a non-light-emitting portion that does not emit light around the light-emitting portion. In the present invention, the light-emitting portion may overlap an opening OA provided on the substrate 110. For example, when the substrate 110 is a plastic substrate, it may include polyimide or polyamide.

[0051] Each light emitting device 170a may be provided with various signal lines, such as data signal lines and gate signal lines, transistors, such as a driving thin film transistor, a switching thin film transistor and a sensing thin film transistor, and circuit elements, such as capacitors, on the substrate 110. For convenience of explanation, the present invention illustrates one transistor TFT for driving each light emitting device 170a.

[0052] The transistor TFT includes an active layer 37, 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 both sides of the active layer 37.

[0053] The active layer 37 may include a source region 31 and a drain region 33 on either side of a channel region 35. The source region 31 and the drain region 33 may each be formed of a semiconductor material doped with n-type or p-type impurities. The channel region 35 overlapping with the gate electrode 43 may be formed of a semiconductor material not doped with n-type or p-type impurities.

[0054] The gate electrode 43 may be provided to overlap the channel region 35 of the active layer 37 with the gate insulating film 41 sandwiched therebetween and with the same width. The gate insulating film 41 may overlap the channel region 35 of the active layer 37 with the same pattern as the gate electrode 43. For example, the gate electrode 43 may be a single layer or a multilayer made of any one of molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), and copper (Cu), or an alloy thereof. Meanwhile, the gate insulating film 41 may be made of an inorganic insulating material, for example, a silicon oxide film (SiOx), a silicon nitride film (SiNx), a silicon oxynitride film (SiOxNy), or a multilayer made of these.

[0055] Meanwhile, the light-shielding layer 21 on the substrate 110 overlaps at least the channel region 35 of the active layer 37 of the transistor TFT and is disposed below the active layer 37. The light-shielding layer 21 prevents external light from being transmitted to the transistor TFT through the substrate 110. For example, the light-shielding layer 21 may have a structure consisting of a single layer of a metal material such as molybdenum (Mo), titanium (Ti), aluminum-neodymium (AlNd), aluminum (Al), chromium (Cr), or an alloy thereof, or a multi-layer structure using these materials.

[0056] The buffer film 111 on the light-shielding layer 21 can cover the light-shielding layer 21. For example, the buffer film 111 can have a single-layer or multi-layer structure of silicon oxide (SiOx) or silicon nitride (SiNx).

[0057] The interlayer insulating film 112 on the buffer film 111 may include a source contact hole and a drain contact hole exposing the source region 31 and the drain region 33 of the active layer 37, respectively, 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 made of a single layer or multiple layers of a silicon oxide film (SiOx), a silicon nitride film (SiNx), or a silicon oxynitride film (SiOxNy).

[0058] A source electrode 51 and a drain electrode 53 may be provided as the same layer on the interlayer insulating film 112. The source electrode 51 and the drain electrode 53 are 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, respectively. For example, the source electrode 51 and the drain electrode 53 may have a structure consisting of a single layer of a metal material such as molybdenum (Mo), aluminum (Al), chromium (Cr), gold (Au), titanium (Ti), nickel (Ni), neodymium (Nd), copper (Cu), or an alloy thereof, or a multilayer structure using the same.

[0059] The passivation layer 113 on the interlayer insulating film 112 can cover the transistor TFT. Therefore, the transistor TFT can be protected by the passivation layer 113. For example, the passivation layer 113 is a kind of inorganic insulating film, and can be composed of a single layer or multiple layers of a silicon oxide film (SiOx), a silicon nitride film (SiNx), or a silicon oxynitride film (SiOxNx).

[0060] A planarizing film 114 may be provided on the passivation layer 113. The planarizing film 114 may be formed to a thickness sufficient to planarize the surface steps on the upper part of the transistor TFT, and may be formed of an organic insulating film. In some cases, when the planarizing film 114 also serves to protect the transistor TFT, the passivation layer 113 may be omitted. For example, the planarizing film 114 is a type of organic insulating film, and may be any one of photo acryl, polyimide, benzocyclobutene resin, and acrylate, and may be formed in a plurality of layers in some cases.

[0061] A light emitting device 170a including a first lower electrode 171a, an intermediate layer 173, and an upper electrode 175 may be provided on the planarization film 114. The light emitting device 170a may be driven by light being emitted from the intermediate layer 173 due to an electric field being formed between the first lower electrode 171a and the upper electrode 175.

[0062] The first lower electrode 171a may be formed in a multi-layer structure including a transparent conductive film and an opaque conductive film having high reflectivity. The transparent conductive film of the first lower electrode 171a is made of a material having a relatively large work function value, such as indium tin oxide (ITO) or indium zinc oxide (IZO), and the opaque conductive film may be a single layer or multiple layers of any one selected from the group consisting of silver (Ag), aluminum (Al), copper (Cu), molybdenum (Mo), titanium (Ti), nickel (Ni), chromium (Cr), or tungsten (W), or an alloy thereof. For example, the first lower electrode 171a may be formed in a structure in which a transparent conductive film, an opaque conductive film, and a transparent conductive film are sequentially stacked, or a structure in which a transparent conductive film and an opaque conductive film are sequentially stacked.

[0063] The bank 115 covering the edge of the first lower electrode 171a forms an opening OA exposing the light emitting element 170a and may be provided on the entire surface of the planarization film 114. In some cases, the bank 115 may include a light absorbing material. In this case, the bank 115 may include a black dye. Therefore, the display device of the present invention may prevent optical interference and light leakage between adjacent sub-pixels. An intermediate layer 173 may be provided on the first and second lower electrodes 171a and 171b and the bank 115 over the entire region of the substrate 110. Specifically, the intermediate layer 173 may refer to a single stacked organic layer including a hole injection layer, a hole transport layer, an emission layer, an electron transport layer, and an electron injection layer. In some cases, the intermediate layer 173 may have a tandem structure including a plurality of stacks (first stack, second stack) each including a first and second emission layer and a charge generation layer between the stacks. The tandem structure is not limited to the illustrated two-stack structure, but may also be a plurality of stacks of three or more stacks. Here, the first and second emission layers in the plurality of stacks are emission layers of the same color that emit any one of red, green, and blue light, and may be patterned and provided in each of the plurality of sub-pixels SP1, SP2, and SP3.

[0064] The upper electrode 175 on the intermediate layer 173 may be formed on 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 having a thickness thin enough to transmit light.

[0065] An encapsulation layer 180 may be provided on the upper electrode 175 to cover the entire display and non-display regions of the substrate 110. The encapsulation layer 180 prevents oxygen and moisture from penetrating into the light emitting element 170a, thereby extending the life of the light emitting display device. For example, the encapsulation layer 180 may be formed in a form in which one or more pairs of inorganic and organic encapsulation films are stacked.

[0066] 4a, the display device of the present invention may include a first insulating layer 220 provided on the encapsulation layer 180, lenses 240 provided on the first insulating layer 220 corresponding to each of the light emitting elements 170a, a first light blocking pattern 210 provided between the substrate 110 and the first insulating layer 220 corresponding to each of the light emitting elements 170a, and a second light blocking pattern 230 provided on the first insulating layer 220 to overlap the first light blocking pattern 210. In the display device of the present invention according to the first embodiment, a center of the second light blocking pattern 230 and an edge surrounding the center may form a first angle θ1.

[0067] The first insulating layer 220 may be provided on the entire area of ​​the encapsulation layer 180. The first insulating layer 220 according to the first embodiment may have a convex portion CVA in each area corresponding to the non-opening NOA on the substrate 110. The convex portion CVA may be provided along the edge of the lens 240 in the non-opening NOA. Such a convex portion CVA may be in a form that protrudes in the opposite direction to the substrate 110 from the flat portion FA. Meanwhile, the first insulating layer 220 excluding the convex portion CVA may be composed of the flat portion FA. Here, the first insulating layer 220 may be formed to include the flat portion FA and the convex portion CVA by a process using a half-tone mask.

[0068] The convex portion CVA of the first insulating layer 220 may be provided along each edge of the lens 240. In some cases, the edge of the convex portion CVA of the first insulating layer 220 may partially overlap with each edge of the lens 240. That is, the convex portion CVA of the first insulating layer 220 may be located along the edge of the opening OA. The convex portion CVA of the first insulating layer 220 may include an upper surface 220a parallel to the flat portion FA and a side surface 220b inclined from the upper surface 220a toward the substrate 110. In the convex portion CVA of the first insulating layer 220, a first angle θ1 formed between the upper surface 220a and the side surface 220b may be 90° or more and less than 180°. And, a second angle θ2 formed by the side surface 220b of the convex portion CVA with the substrate 110 may be an acute angle. Here, the second angle θ2 of the convex portion CVA with respect to the side surface 220b may be approximately 70° when the vertical distance between the surface of the flat portion FA and the upper surface 220a of the convex portion CVA is approximately 3 μm according to a process method using a halftone mask. The second light-shielding pattern 230 may be disposed on the upper portion of the convex portion CVA of the first insulating layer 220, and the first light-shielding pattern 210 may be disposed on the lower portion. Such a convex portion CVA may form a bend in the second light-shielding pattern 230.

[0069] The flat portion FA of the first insulating layer 220 may form an area excluding the convex portion CVA. The flat portion FA may be connected to the side surface 220b of the convex portion CVA, and the lens 240 may be disposed on the upper portion corresponding to each of the plurality of light emitting elements 170a. In other words, the lens 240 may be disposed on the flat portion FA of the first insulating layer 220 overlapping with the opening OA. Meanwhile, the lens 240 may extend beyond the flat portion FA of the first insulating layer 220 and overlap with a part of the convex portion CVA outside the flat portion FA.

[0070] The first light-shielding pattern 210 and the second light-shielding pattern 230 may be provided on the convex portion CVA with the first insulating layer 220 interposed therebetween. The first light-shielding pattern 210 and the second light-shielding pattern 230 may be made of different materials. Also, the first light-shielding pattern 210 and the second light-shielding pattern 230 may have different reflectances. The first light-shielding pattern 210 and the second light-shielding pattern 230 may have different widths, and one of them may be formed to be inclined from the center to the edge. In the display device according to the first embodiment, the second width W2 of the second light-shielding pattern 230 may be wider than the first width W1 of the first light-shielding pattern 210, and the edge of the second light-shielding pattern 230 may be formed to be inclined more than the center.

[0071] The first light-shielding pattern 210 may be provided on the sealing layer 180 except for a predetermined region corresponding to the opening OA. The first light-shielding pattern 210 may be provided so as to overlap with the upper surface 220a of the convex portion CVA between the flat portions FA of the first insulating layer 220. The first light-shielding pattern 210 may expose at least the second light-shielding pattern 230 overlapping with the side surface 220b of the first insulating layer 220 to the substrate 110 side. In addition, the first light-shielding pattern 210 may expose even the second light-shielding pattern 230 overlapping with the edge portion of the upper surface 220a connected to the side surface 220b of the first insulating layer 220 to the substrate 110 side, taking into consideration the angle at which light from the light-emitting element is incident. In other words, the first light-shielding pattern 210 may partially overlap with the upper surface 220a of the first insulating layer 220.

[0072] 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. Such a first light-shielding pattern 210 may prevent light interference and light leakage between adjacent sub-pixels. Even if the first light-shielding pattern 210 includes a light-absorbing material, it may have a certain amount of reflectance. The first light-shielding pattern 210 including a general light-absorbing material may have a reflectance of about 4.6%.

[0073] The second light-shielding pattern 230 may be provided on the convex portion CVA of the first insulating layer 220. That is, the second light-shielding pattern 230 may be provided along the edge of each lens 240. The second light-shielding pattern 230 may be provided along the shape of the upper surface 220a and the side surface 220b of the convex portion CVA of the first insulating layer 220. The second light-shielding pattern 230 is divided into a center portion contacting the upper surface 220a of the convex portion CVA of the first insulating layer 220 and an edge portion contacting the side surface 220b, and may have an inclined shape from the center to the edge portion according to the shape of the convex portion CVA of the first insulating layer 220. In other words, the edge portion of the second light-shielding pattern 230 may form a first angle θ1 with respect to the center portion. Here, the first angle θ1 may be 90° or more and less than 180° according to the shape of the convex portion CVA of the first insulating layer 220. In addition, the second light-shielding pattern 230 has a center portion contacting the upper surface 220a of the convex portion CVA of the first insulating layer 220 overlapping the first light-shielding pattern 210, and an edge portion contacting the side surface 220b of the convex portion CVA of the first insulating layer 220 may be exposed to the substrate 110 side from the first light-shielding pattern 210. Thus, the light of the light emitting element 170a traveling between the lenses 240 may be incident on the second light-shielding pattern 230 exposed from the first light-shielding pattern 210, and when the light is reflected between the first light-shielding pattern 210 and the second light-shielding pattern 230 by the inclined edge of the second light-shielding pattern 230 or is reflected at an acute angle by the inclined edge of the second light-shielding pattern 230 and is re-reflected by a component such as a metal on the light emitting element 170a side, the light travels to a region farther than the adjacent lens, so that the probability of the light reaching another lens other than the lens may be reduced. Therefore, the amount of light from the light emitting device 170a traveling between the lenses 240 that reaches other lenses can be significantly reduced.

[0074] 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 includes a number of crossed transmitting electrodes and a number of receiving electrodes, and may sense a touch based on a change in capacitance between the number of transmitting electrodes and the number of receiving electrodes. Referring to FIG. 2, the illustrated second light-shielding pattern 230 may be one of the transmitting electrodes and the receiving electrodes in the case of a touch electrode, and may further include a connection electrode that electrically connects the transmitting electrode and the receiving electrode. The second light-shielding pattern 230 made of a typical metal material may have a reflectance of about 50%.

[0075] Referring to FIG. 4b, the light emitted from the light emitting element 170a on the substrate 110 may pass through the opening OA and may partially proceed to the non-opening NOA side. The light emitted from the light emitting element 170a proceeding to the non-opening NOA may reach the first light blocking pattern 210 and the second light blocking pattern 230 between the lenses 240. Referring to LE11, LE12, and LE13 in FIG. 4b, a part of the light emitted from the light emitting element 170a reaching the first light blocking pattern 210 may be absorbed, and the remaining part may be reflected LE12 to the light emitting array 100 including the light emitting element 170a. Then, the light may be re-reflected LE13 to another lens other than the lens by a configuration such as the lower electrode or upper electrode of the light emitting element 170a. In this way, the light that reaches the planar first light blocking pattern 210 is reflected and re-reflected to another lens other than the lens, so light leakage may occur. However, in the present invention, the first light-shielding pattern 210 has a narrower width than the second light-shielding pattern 230, and the width between the lenses 240 is narrower, thereby minimizing the width of the planar reflective element.

[0076] In addition, the present invention can significantly reduce the reflection and re-reflection of the light emitted from the light emitting element 170a to other lenses by using the center and the edges inclined relative to the center, as shown in LE21 and LE22 in Fig. 4b. Referring to LE21 and LE22, a part of the light emitted from the light emitting element 170a that reaches the second light blocking pattern 230 exposed from the first light blocking pattern 210 is absorbed, and the remaining part is reflected. Here, this light is reflected toward the first light blocking pattern 210 due to the inclined shape of the second light blocking pattern 230, and can be repeatedly re-reflected and absorbed between the first light blocking pattern 210 and the second light blocking pattern 230 as LE22. In this manner, the light LE21 that reaches the second light-shielding pattern 230 that contacts the side surface 220b of the convex portion CVA of the first insulating layer 220 is confined between the first light-shielding pattern 210 and the second light-shielding pattern 230, and is prevented from traveling to other lenses other than the corresponding lens, thereby preventing light leakage.

[0077] Meanwhile, the planarization layer 250 may be provided on the first insulating layer 220 including the second light-shielding pattern 230 and the lenses 240. The planarization layer 250 may planarize the surface steps generated by the surface of the first insulating layer 220, the second light-shielding pattern 230 on the first insulating layer 220, and the lenses 240. For example, the planarization layer 250 may be made of a type of organic insulating material.

The fourth light-shielding pattern 231c may be provided on a portion of the first light-shielding pattern 210 and may include a metal. Here, the fourth light-shielding pattern 231c may be a connection electrode that connects between a plurality of first light-shielding patterns 210 when the first light-shielding pattern 210 is a touch electrode. In this case, the fourth light-shielding pattern 231c may be electrically connected to the first light-shielding pattern 210.

The recess CCA may be provided along the edge of the lens 340. Such a recess CCA may be recessed toward the substrate 110 from the flat portion FA. Meanwhile, the first insulating layer 320 excluding the recess CCA may be composed of the flat portion FA.

[0085] The recess CCA of the first insulating layer 320 may partially overlap with each edge of the lens 340. The recess CCA may include a bottom surface 320a parallel to the flat portion FA, and a side surface 320b between the bottom surface 320a and a surface of the flat portion FA adjacent to the bottom surface 320a. The bottom surface 320a and the side surface 320b of the recess CCA may form a first angle θ1. Here, the first angle θ1 may be greater than or equal to 90° and less than 180°. In addition, the side surface 320b of the recess CCA may form a second angle θ2 with the substrate 110. Here, the second angle θ2 may be an acute angle. The second light-shielding pattern 330 may be disposed on the upper portion of the recess CCA of the first insulating layer 320, and the first light-shielding pattern 310 may be disposed on the lower portion. Here, the recess CCA may form a bend in the second light-shielding pattern 330.

[0086] The first light-shielding pattern 310 and the second light-shielding pattern 330 may be provided in each recess CCA with the first insulating layer 320 interposed therebetween. The first light-shielding pattern 310 and the second light-shielding pattern 330 may be made of different materials. Also, the first light-shielding pattern 310 and the second light-shielding pattern 330 may have different reflectances. The first light-shielding pattern 310 and the second light-shielding pattern 330 may have different widths, and one of the first light-shielding patterns 310 and the second light-shielding pattern 330 may be formed to be inclined from the center to the edge. In the display device according to the second embodiment, the second width W2 of the second light-shielding pattern 330 may be wider than the first width W1 of the first light-shielding pattern 310, and the edge of the second light-shielding pattern 330 having the relatively wider width may be formed to be inclined.

[0087] The first light-shielding pattern 310 may be provided on the sealing layer 180 except for a predetermined region corresponding to the opening OA. The first light-shielding pattern 310 may overlap with a bottom surface 320a in a recess CCA between flat portions FA of the first insulating layer 320. That is, the first light-shielding pattern 310 may expose at least the second light-shielding pattern 330 overlapping with the side surface 320b of the first insulating layer 320 to the substrate 110 side.

[0088] The second light-shielding pattern 330 may be provided on the recess CCA of the first insulating layer 320. That is, the second light-shielding pattern 330 may be provided along the edge of each lens 340. The second light-shielding pattern 330 may be provided along the shape of the bottom surface 320a and the side surface 320b of the recess CCA of the first insulating layer 320. The second light-shielding pattern 330 may be divided into a center portion contacting the bottom surface 320a of the recess CCA of the first insulating layer 320 and an edge portion contacting the side surface 320b, and may be formed to be inclined according to the shape of the recess CCA of the first insulating layer 320 from the center portion to the edge portion. In other words, the edge portion of the second light-shielding pattern 330 may be inclined at a predetermined angle with respect to the substrate 110, i.e., the second angle θ2 due to the first insulating layer 320. In addition, the second light-shielding pattern 330 may have a center portion in contact with the bottom surface 320a of the recess CCA of the first insulating layer 320 overlapping with the first light-shielding pattern 310.

[0094] 8 is a plan view of a display device according to a third and fourth embodiment of the present invention. In FIG. 8, the plan views of the third and fourth embodiments are the same, so the reference numerals of the third embodiment are representatively used. FIG. 9 is a cross-sectional view taken along line III-III' of FIG. 8 according to the third embodiment, and FIG. 8 is a cross-sectional view of the fourth embodiment, which is another embodiment of FIG. 8.

[0098] FIG. 9 is a cross-sectional view taken along line III-III' of FIG. 8 according to the third embodiment.

[0099] 9, the third embodiment of the present invention may include a second insulating layer 423 between the encapsulation layer 180 and the first insulating layer 421. And, 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 invention, a bend may be formed in the first light-shielding pattern 410 via the second insulating layer 423.

[0100] The first and second insulating layers 421, 423 may be provided on the entire surface of the sealing layer 180. The second insulating layer 423 according to the third embodiment may have a convex portion CVA for each region corresponding to the non-opening portion NOA on the substrate 110. The convex portion CVA may be provided along the edge of the lens 240 within the non-opening portion NOA. Such a convex portion CVA may be a portion that protrudes in the opposite direction to the substrate 110 from the flat portion FA. Meanwhile, the second insulating layer 423 excluding the convex portion CVA may be the flat portion FA.

[0101] The convex portion CVA of the second insulating layer 423 may be provided along each edge of the lens 440. In some cases, the edge of the convex portion CVA of the second insulating layer 423 may partially overlap each edge of the lens 440. The convex portion CVA of the second insulating layer 423 may include an upper surface 423a parallel to the flat portion FA and a side surface 423b inclined from the upper surface 423a toward the substrate 110. A first angle θ1 formed between the upper surface 423a and the side surface 423b of the convex portion CVA may be 90° or more and less than 180°. A second angle θ2 formed by the side surface 423b of the convex portion CVA with the substrate 110 may be an acute angle. A first light-shielding pattern 410 may be disposed on the upper portion of the convex portion CVA of the second insulating layer 423.

[0102] The first insulating layer 421 may be provided on the second insulating layer 423 and the first light-shielding pattern 410. A lens 440 may be provided on the upper portion of the first insulating layer 421 in a region overlapping with the flat portion FA of the second insulating layer 423, and a second light-shielding pattern 430 may be provided in a region overlapping with the convex portion CVA of the second insulating layer 423. Meanwhile, the lens 440 may extend beyond the flat portion FA of the second insulating layer 423 and overlap with a part of the convex portion CVA outside the flat portion FA.

[0103] The first light-shielding pattern 410 and the second light-shielding pattern 430 may be provided on the convex portion CVA with a 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. Also, the first light-shielding pattern 410 and the second light-shielding pattern 430 may have different reflectances. In the display device according to the third embodiment, the first width W1 of the first light-shielding pattern 410 may be wider than the second width W2 of the second light-shielding pattern 430, and the edge of the first light-shielding pattern 410 having the relatively wider width may be formed to be inclined.

[0104] The first light-shielding pattern 410 may be provided on the convex portion CVA of the second insulating layer 423. That is, the first light-shielding pattern 410 may be provided along the edge of each lens 440. The first light-shielding pattern 410 may be provided along the shape of the upper surface 423a and the side surface 423b of the convex portion CVA of the second insulating layer 423. The first light-shielding pattern 410 may be divided into a center portion contacting the upper surface 423a of the convex portion CVA of the second insulating layer 423 and an edge portion contacting the side surface 423b, and may be formed to be inclined according to the shape of the convex portion CVA of the second insulating layer 423 from the center portion to the edge portion. In other words, the edge portion of the first light-shielding pattern 410 may be formed to be inclined to form a predetermined angle with respect to the substrate 110, i.e., a second angle θ2 due to the second insulating layer 423. In addition, the first light-shielding pattern 410 may have a center portion contacting the upper surface 423a of the convex portion CVA of the second insulating layer 423 overlapping the second light-shielding pattern 430, and an edge portion contacting the side surface 423b of the convex portion CVA of the second insulating layer 423 may be exposed to the opposite side of the substrate 110 from the second light-shielding pattern 430. Thus, the light of the light emitting element 170a traveling between the lenses 440 is reflected at an acute angle by the inclined edge of the first light-shielding pattern 410 and re-reflected by a reflective component on the light emitting element 170a side, thereby reducing the amount of light reaching other lenses other than the lens. Here, the reflective component on the light emitting element 170a side may include a lower electrode (171a in FIG. 3) and an upper electrode (175 in FIG. 3).

[0105] Meanwhile, the second light-shielding pattern 430 may be provided on the first insulating layer 421. The second light-shielding pattern 430 may overlap an upper surface 423a of the convex portion CVA between the flat portions 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 a minimum width in order to minimize interference between the metals. However, the second light-shielding pattern 430 according to the third embodiment of the present invention is not limited thereto, and may overlap an adjacent lens 440 in some cases.

[0106] FIG. 10 is a cross-sectional view taken along line III-III' of FIG. 8 according to the fourth embodiment.

[0107] 10, the second insulating layer 523 according to the fourth embodiment may have a recess CCA in each region corresponding to the non-opening NOA. The recess CCA may be provided along the edge of the lens 540. The recess CCA may be recessed toward the substrate 110 rather than the flat portion FA. Meanwhile, the second insulating layer 523 excluding the recess CCA may be the flat portion FA.

[0108] The recess CCA of the second insulating layer 523 may partially overlap with each edge of the lens 540. The recess CCA may include a bottom surface 523a parallel to the flat portion FA, and a side surface 523b between the bottom surface 523a and a surface of the flat portion FA adjacent to the bottom surface 523a. The side surface 523b of the recess CCA and the bottom surface 523a may form a first angle θ1. Here, the first angle θ1 may be greater than or equal to 90° and less than 180°. The side surface 523b of the recess CCA may form a second angle θ2 with the substrate 110. Here, the second angle θ2 of the side surface 523b of the recess CCA may be an acute angle. A first light-shielding pattern 510 may be disposed on the upper portion of the recess CCA of the second insulating layer 523. Here, the recess CCA may form a bend in the first light-shielding pattern 510.

[0109] The first light-shielding pattern 510 and the second light-shielding pattern 530 may be provided in each recess CCA with a 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. Also, the first light-shielding pattern 510 and the second light-shielding pattern 530 may have different reflectances. In the display device according to the fourth embodiment, the first width W1 of the first light-shielding pattern 510 may be wider than the second width W2 of the second light-shielding pattern 530, and the edge of the first light-shielding pattern 510 having the relatively wider width may be formed to be inclined.

[0110] The first light-shielding pattern 510 may be provided on the recess CCA of the second insulating layer 523. That is, the first light-shielding pattern 510 may be provided along the edge of each lens 540. Also, the first light-shielding pattern 510 may be provided on the second insulating layer 523 except for a predetermined region corresponding to the recess CCA. Such a first light-shielding pattern 510 may be formed in a shape corresponding to the shape of the bottom surface 523a and the side surface 523b of the recess CCA of the second insulating layer 523. The first light-shielding pattern 510 is divided into a center portion contacting the bottom surface 523a of the recess CCA of the second insulating layer 523 and an edge portion contacting the side surface 523b, and may be inclined from the center to the edge portion according to the shape of the recess CCA of the second insulating layer 523. In other words, the edge portion of the first light-shielding pattern 510 may be inclined at a predetermined angle with respect to the substrate 110, that is, the second angle θ2 due to the second insulating layer 523. In addition, the first light-shielding pattern 510 has a center portion contacting the bottom surface 523a of the recess CCA of the second insulating layer 523 overlapping the second light-shielding pattern 530, and an edge portion contacting the side surface 523b of the recess CCA of the second insulating layer 523 may be exposed to the opposite side of the substrate 110 from the second light-shielding pattern 530. Thus, the light of the light emitting element 170a traveling between the lenses 540 is reflected at an acute angle by the inclined edge of the first light-shielding pattern 510 and re-reflected by a reflective component on the light emitting element 170a side, thereby reducing the amount of light reaching other lenses other than the lens.

[0111] Meanwhile, the second light-shielding pattern 530 may be provided on the first insulating layer 521. The second light-shielding pattern 530 may overlap a bottom surface 523a of the recess CCA between the flat portions FA of the second insulating layer 523. Since the second light-shielding pattern 530 is made of metal, the second light-shielding pattern 530 provided between the flat portions FA, i.e., between the lenses 540, may be formed to have a minimum width in order to minimize interference between the metals. However, the second light-shielding pattern 530 according to the fourth embodiment of the present invention is not limited thereto, and may overlap an adjacent lens 540 in some cases.

[0112] FIG. 11 is a diagram showing modified examples of the areas A3 and A4 in FIGS. 9 and 10, respectively.

Although not shown, a light blocking pattern including the same material as the first light blocking patterns 410 and 510 may be disposed on the second light blocking patterns 430 and 530.

[0114] 11A, a third light-shielding pattern 431a may be disposed on the first light-shielding pattern 410. The third light-shielding pattern 431a may be provided on a portion of the first light-shielding pattern 410 and may include metal. Here, when the first light-shielding pattern 410 is a touch electrode, the third light-shielding pattern 431a may be a connection electrode that connects between 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.

[0115] 11(b), a third light-shielding pattern 531a may be disposed on the first light-shielding pattern 510. The third light-shielding pattern 531a may be provided on a portion of the first light-shielding pattern 510 and may include metal. Here, when the first light-shielding pattern 510 is a touch electrode, the third light-shielding pattern 531a may be a connection electrode that connects between 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.

[0116] FIG. 12 is a cross-sectional view of a display device according to a fifth embodiment of the present invention.

[0117] In the display device according to the fifth embodiment of the present invention, a first light-shielding pattern 611 corresponding to the non-opening NOA is provided on the encapsulating layer 180, a first insulating layer 620 is provided over the entire substrate 110 on the first light-shielding pattern 611, a second light-shielding pattern 630 and a third light-shielding pattern 613 are provided on the convex portion CVA of the first insulating layer 620, and a lens 640 may be provided on the flat portion FA of the first insulating layer 620 overlapping with the opening OA.

[0118] The first insulating layer 620 may be provided on the entire surface of the sealing layer 180. The first insulating layer 620 according to the fifth embodiment may have a convex portion CVA for each region corresponding to the non-opening portion NOA of the substrate 110. The convex portion CVA may be provided along the edge of the lens 640 in the non-opening portion NOA. Meanwhile, the first insulating layer 620 excluding the convex portion CVA may be a flat portion FA.

[0119] The convex portion CVA of the first insulating layer 620 may be provided along each edge of the lens 640. The convex portion CVA of the first insulating layer 620 may be located along the edge of the opening OA. The convex portion CVA of the first insulating layer 620 may include an upper surface 620a parallel to the flat portion FA and a side surface 620b inclined from the upper surface 620a toward the substrate 110. A first angle θ1 formed between the upper surface 620a and the side surface 620b of the convex portion CVA may be 90° or more and less than 180°. A second angle θ2 formed by the side surface 620b of the convex portion CVA with the substrate 110 may be an acute angle. The second light-shielding pattern 630 and the third light-shielding pattern 613 may be sequentially arranged on the upper portion of the convex portion CVA of the first insulating layer 620, and the first light-shielding pattern 611 may be arranged on the lower portion. Here, the convex portion CVA may form a bend in the third light-shielding pattern 613.

[0120] The flat portion FA of the first insulating layer 620 may be a portion of the first insulating layer 620 excluding the convex portion CVA. A lens 640 may be disposed on the flat portion FA of the first insulating layer 620 corresponding to the opening OA. A flat layer 650 may be in contact with an upper portion of the first insulating layer 620 where the lens 640 and the second and third light blocking patterns 630 and 613 are not disposed.

[0121] A lens 640 may be provided on the flat portion FA of the first insulating layer 620 overlapping with the opening OA. The lens 640 may extend beyond the flat portion FA of the first insulating layer 620 and partially overlap with the convex portion CVA outside the flat portion FA.

[0122] The first light-shielding pattern 611 and the second light-shielding pattern 630 may be provided on the convex portion CVA with the first insulating layer 620 interposed therebetween. Also, the third light-shielding pattern 613 may be provided on the convex portion CVA to cover 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 have similar reflectance. Also, the first and third light-shielding patterns 611 and 613 may be made of different materials from the second light-shielding pattern 630. Also, the first and third light-shielding patterns 611 and 613 may have different reflectances from the second light-shielding pattern 630. In the display device according to the fifth embodiment, the first to third light-shielding patterns 611, 630, and 613 may have different first to third widths W1, W2, and W3, and any one of them may be formed to be inclined from the center to the edge. Specifically, the first and second widths W1 and W2 of the first and second light blocking patterns 611 and 630, respectively, may be smaller than the third width W3 of the third light blocking pattern 613. Since the second light blocking pattern 630 is made of metal, the second light blocking pattern 630 provided between the lenses 440 may be formed to have a minimum width in order to minimize interference between the metals. Therefore, the second light blocking pattern 630 may have a smaller width than the first light blocking pattern 611. In addition, the edge of the third light blocking pattern 613 may be formed to be inclined.

[0123] The first light-shielding pattern 611 may be provided on the sealing layer 180 except for a predetermined region corresponding to the opening OA. The first light-shielding pattern 611 may overlap an upper surface 620a of the convex portion CVA between the flat portions FA of the first insulating layer 620. The first light-shielding pattern 611 may expose a third light-shielding pattern 613 overlapping at least a side surface 620b of the first insulating layer 620 to the substrate 110 side.

[0124] The second light-shielding pattern 630 may be provided on the convex portion CVA of the first insulating layer 620. That is, the second light-shielding pattern 630 may be provided along the edge of each lens 240. Such a second light-shielding pattern 630 may overlap with an upper surface 620a of the convex portion CVA between the flat portions FA of the first insulating layer 620. The first light-shielding pattern 611 may expose a third light-shielding pattern 613 overlapping at least a side surface 620b of the first insulating layer 620 to the substrate 110 side.

[0125] The third light-shielding pattern 613 may be provided on the convex portion CVA of the first insulating layer 620. The third light-shielding pattern 613 may be provided on the second light-shielding pattern 630 so as to cover the entire surface of the second light-shielding pattern 630. The third light-shielding pattern 613 may be provided along the shape of the upper surface 620a and the side surface 620b of the convex portion CVA of the first insulating layer 620. The third light-shielding pattern 613 is divided into a center portion contacting the upper surface 620a of the convex portion CVA of the first insulating layer 620 and an edge portion contacting the side surface 620b, and the edge portion of the third light-shielding pattern 613 may be formed to be inclined with respect to the center portion according to the shape of the convex portion CVA of the first insulating layer 620. In other words, the edge portion of the third light-shielding pattern 613 may form an acute second angle θ2 with the substrate 110. In addition, the third light-shielding pattern 613 has a center portion contacting an upper surface 620a of the convex portion CVA of the first insulating layer 620 overlapping with the first light-shielding pattern 611, and an edge portion contacting a side surface 620b of the convex portion CVA of the first insulating layer 620 may be exposed to the substrate 110 side from the first light-shielding pattern 611. Thus, the light of the light emitting element 170a traveling between the lenses 240 may be incident on the second light-shielding pattern 230 exposed from the first light-shielding pattern 611, and may be reflected between the first light-shielding pattern 611 and the second light-shielding pattern 630 by the inclined edge portion of the third light-shielding pattern 613 or may be reflected at an acute angle and re-reflected by a reflective component on the light emitting element 170a side, thereby reducing the amount of light reaching other lenses other than the lens.

[0126] Next, Fig. 13a to Fig. 13d are graphs showing the light intensity depending on the viewing angle of the display device according to the first to fourth embodiments of the present invention. Fig. 13a shows the light intensity depending on the viewing angle of the display device according to the first embodiment, which was 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 edge length of the second light-shielding pattern 230 is 3 μm, and the second angle θ2 is 70° based on Fig. 4a. Fig. 13b shows the light intensity depending on the viewing angle of the display device according to the second embodiment, which was 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 edge length of the second light-shielding pattern 330 is 3 μm, and the second angle θ2 is 70° based on Fig. 6. FIG. 13c shows the light intensity depending on the viewing angle of the display device according to the third embodiment, and 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 edge length of the first light-shielding pattern 410 is 3 μm, and the second angle θ2 is 70°, based on FIG. 9. FIG. 13d shows the light intensity depending on the viewing angle of the display device according to the fourth embodiment, and 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 edge length of the first light-shielding pattern 510 is 3 μm, and the second angle θ2 is 70°, based on FIG. 10. In each graph, the horizontal axis shows the viewing angle (°), and the vertical axis shows the light intensity (%), with the intensity at a viewing angle of 0° being 100%.

[0127] The following table shows the peak values ​​shown in Figures 13a to 13d. The second peak means the second largest peak value, and the high angle peak means the largest peak value at a viewing angle of 60° or more. In the following table, the conventional structure shows a display device in which the first and second light blocking patterns are parallel to each other and not inclined, the line width of the first light blocking pattern is 12.6 μm, and the line width of the second light blocking pattern is 11 μm, and they overlap each other. [Table 1]

[0128] Referring to Table 1, the first embodiment has the smallest second peak value, and the third and fourth embodiments have the smallest high-angle peak value. Since light intensity of about 0.1% cannot be easily recognized by the human visual field, most of the first to fourth embodiments are considered to have almost no light leakage at the high-angle peak. Therefore, the display device according to the first embodiment has the smallest light leakage, since the second peak is 0.11 and the high-angle peak is 0.07. Meanwhile, the second peak of the conventional structure is 0.61, whereas the second peak of the display devices according to the first to fourth embodiments of the present invention is lower than the conventional structure. Therefore, the display device according to the present invention can improve the cut-off effect against the viewing angle restriction by the lens by forming the edge of either the first or second light-shielding pattern at an angle, and can have the effect of reducing the light leakage phenomenon. In particular, the display device according to the first embodiment of the present invention has a second peak of 0.11, and can remarkably prevent light leakage and have a remarkable cut-off effect compared to the conventional structure.
