For example, the display device 1000 may provide an image to the outside by using light emitted through the display area DA.

[0058] The display area DA may include a plurality of pixel areas PA, for example, first, second, and third pixel areas PA1, PA2, and PA3. For example, the first, second, and third pixel areas PA1, PA2, and PA3 may correspond to red, green, and blue pixels, respectively.

[0059] The pixel areas PA may each be systematically arranged in the display area DA. Figure 1AThe pixel areas PA are shown to be arranged to form columns and rows, but the arrangement of the pixel areas PA may be modified in various ways as appropriate. For example, the pixel areas PA may be arranged in a PenTile type (eg, a PenTile matrix).

[0063] refer to Figure 1B , the display device 1000 may include a display panel 400 and a color panel 100 disposed on the display panel 400 .

[0064] The display panel 400 may include a plurality of pixels (eg, PX1, PX2, and PX3) that emit light based on electrical signals. The light emitted by the display panel 400 may be directed toward the color panel 100, and the light L1, L2, and L3 that pass through the color panel 100 may be output to the outside.

[0065] Each pixel in the display panel 400 may include an emission element that emits light and a pixel circuit that controls the emission element. For example, the display panel 400 may include an organic light emitting diode (OLED) as the emission element.

[0066] Hereinafter, as an example, the display device 1000 according to one or more embodiments is described as an organic light-emitting display device, but the present disclosure is not limited thereto. For example, the display device 1000 according to one or more embodiments may be an inorganic light-emitting display including an inorganic light-emitting diode as an emission element or a quantum dot light-emitting display including a quantum dot as an emission element. For example, the emission layer of the emission element provided in the display panel 400 may include an organic material, an inorganic material, a quantum dot, an organic material and a quantum dot, an inorganic material and a quantum dot, or each of an organic material, an inorganic material and a quantum dot. In some embodiments, the display device 1000 may be a liquid crystal display device (LCD) including a backlight unit and a liquid crystal layer.

[0067] The color panel 100 may include at least one of a color filter and a color conversion element in an area overlapping with the pixels PX1, PX2, and PX3 of the display panel 400. For example, light incident on the color panel 100 may be converted or transmitted based on the characteristics of at least one of the color filter and the color conversion element and output to the outside. For example, the display device 1000 may output light L1, L2, and L3 having different color characteristics according to the pixels PX1, PX2, and PX3 according to the characteristics of the color panel 100 overlapping with each of the pixels.

[0068] Figure 2A is a cross-sectional view of a color panel 100 according to an embodiment.

[0069] For example, Figure 2A Can be used as Figure 1A 0 is a schematic cross-sectional view of a color panel 100 when a display device 1000 is cut along line II′.

[0070] refer to Figure 2A , the color panel 100 according to one or more embodiments may include a substrate 110 , a color filter layer 120 , a color conversion layer 140 , and a planarization layer 150 .

[0071] The substrate 110 may include a display area DA including a plurality of pixel areas (eg, first, second, and third pixel areas PA1, PA2, and PA3) spaced apart from one another, and a non-display area NDA including no pixel area.

[0072] The color conversion layer 140 may include a color conversion element including a plurality of quantum dots that convert light Li incident on the color panel 100 into light L1 , light L2 , and light L3 in a specific (or set) wavelength band.

[0073] The color conversion layer 140 may include a first element 142 , a second element 144 , a third element 146 , and a dummy element 148 .

[0074] For example, in the display area DA, the color conversion layer 140 may include a first element 142 covering the first pixel area PA1, a second element 144 covering the second pixel area PA2, and a third element 146 covering the third pixel area PA3.

[0075] The first element 142 may be a first color conversion element including a first quantum dot for converting incident light Li into light L1 of a first wavelength band and outputting the converted light L1.

[0076] The second element 144 may be a second color conversion element including second quantum dots for converting the incident light Li into light L2 of a second wavelength band and outputting the converted light L2.

[0077] The size and structure of the first quantum dot may be different from the size and structure of the second quantum dot. For example, the first quantum dot and the second quantum dot may have different particle sizes, respectively, and thus emit light L1 and light L2 having different color characteristics to the outside. For example, the light L1 in the first wavelength band and the light L2 in the second wavelength band may each have a wavelength value greater than the wavelength value of the incident light Li.

[0078] The third element 146 may be a light-transmitting element including light scattering particles that transmit the incident light Li and not including specific quantum dots. For example, the wavelength band of the light L3 output through the third element 146 may be the same as the wavelength band of the incident light Li incident on the third element 146.

[0079] For example, light L1 output through the first pixel region PA1 may have a wavelength corresponding to red light, light L2 output through the second pixel region PA2 may have a wavelength corresponding to green light, and light L3 output through the third pixel region PA3 may have a wavelength corresponding to blue light.

[0080] The color conversion element (e.g., the first color conversion element and / or the second color conversion element) may include a photosensitive polymer in which quantum dots and light scattering particles are distributed. The quantum dots may convert incident light Li into light of a specific wavelength band and output the converted light. The photosensitive polymer may be an organic material having light transmittance. The light scattering particles may scatter a portion of the incident light Li that is not absorbed by the quantum dots to allow more quantum dots to be excited, thereby increasing the color conversion rate of the color conversion element. For example, the light scattering particles may include titanium oxide (TiO 2 ) and / or metal particles.

[0081] The core of the quantum dot may be selected from Group II-VI compounds, Group III-V compounds, Group IV-VI compounds, Group IV elements, Group IV compounds, and combinations thereof.

[0084] The IV-VI group compound may be selected from the following: a binary compound selected from SnS, SnSe, SnTe, PbS, PbSe, PbTe and combinations thereof; a ternary compound selected from SnSeS, SnSeTe, SnSTe, PbSeS, PbSeTe, PbSTe, SnPbS, SnPbSe, SnPbTe and combinations thereof; and a quaternary compound selected from SnPbSSe, SnPbSeTe, SnPbSTe and combinations thereof. The IV group element may be selected from Si, Ge and combinations thereof. The IV group compound may be a binary compound selected from SiC, SiGe and combinations thereof.

[0085] In one or more embodiments, the binary compound, ternary compound, and quaternary compound may be each independently present in a particle at a uniform concentration, or in the same particle in a state of being partially divided according to different concentrations. The quantum dot may also have a core-shell structure in which one quantum dot surrounds another quantum dot. The interface between the core and the shell may have a concentration gradient in which the concentration of the element in the shell decreases toward the center.

[0086] In some embodiments, the quantum dot may have a core-shell structure, which includes a core containing the above-mentioned nanocrystals and a shell surrounding the core. The shell of the quantum dot can be used as a protective layer to prevent (or reduce) chemical changes in the core, and can maintain the characteristics of a semiconductor and / or a charging layer for imparting electrophoretic properties to the quantum dot. The shell may include a single layer or multiple layers. The interface between the core and the shell may have a concentration gradient, wherein the concentration of the element in the shell decreases toward the center. The shell in the quantum dot may include, for example, an oxide of a metal or non-metal, a semiconductor compound, a combination thereof, and / or the like.

[0087] For example, metal or non-metal oxides may include, for example, SiO 2 、Al 2 O 3 、TiO 2 、ZnO、MnO、Mn 2 O 3 , CuO, FeO, Fe 2 O 3 , Fe 3 O 4 , CoO, Co 3 O 4 and / or binary compounds of NiO and / or such as MgAl 2 O 4 、CoFe 2 O 4 、NiFe 2 O 4 and / or CoMn 2 O 4 ternary compound, but the present embodiment is not limited thereto.

[0088] The semiconductor compound may include, for example, Cds, CdSe, CdTe, ZnS, ZnSe, ZnTe, ZnSeS, ZnTeS, GaAs, GaP, GaSb, HgS, HgSe, HgTe, InAs, InP, InGaP, InSb, AlAs, AlP, AlSb and / or the like, but the present embodiment is not limited thereto.

[0089] The full width at half maximum (FWHM) of the quantum dot can be about 45nm or less, for example, about 40nm or less, or about 30nm or less, and the color purity or color gamut can be improved within the above range. In addition, since the light emitted from the quantum dot is irradiated in all directions, the field angle of light can be widened.

[0090] The shape of the quantum dot can be any suitable shape used in the technical field, and there is no particular limitation. For example, the quantum dot can include spherical, pyramidal, multi-armed and / or cubic nanoparticles, nanotubes, nanowires, nanofibers, nanosheet-like particles and / or the like.

[0091] The color of emitted light can be adjusted according to the size of particles of quantum dots, and thus, quantum dots can have various appropriate emission colors, such as blue, red, and green.

[0092] The color conversion layer 140 may include at least one dummy element 148 located in the non-display area NDA. The dummy element 148 may be arranged separately from the display area DA. In some embodiments, the dummy element 148, the first element 142, the second element 144, and the third element 146 may be arranged separately from each other.

[0093] Dummy element 148 may include the same material as that of one of the elements (e.g., first element 142, second element 144, and third element 146) provided in display area DA of color conversion layer 140. For example, dummy element 148 may include the same material as that of any one of the first color conversion element, the second color conversion element, and the light-transmitting element.

[0094] In an example, the dummy element 148 may include a photosensitive polymer in which quantum dots (e.g., any one of the first quantum dots and the second quantum dots) and light scattering particles are distributed. In another example, the dummy element 148 may include a photosensitive polymer in which light scattering particles are distributed, but may not include quantum dots.

[0095] For example, based on the arrangement rule of the pixel areas PA in the display area DA, the dummy element 148 may include the same material as that of a specific element (e.g., the first element 142, the second element 144, and / or the third element 146) covering the pixel areas PA. According to an embodiment, when the pixel areas PA corresponding to red, green, and blue are alternately arranged in the display area DA, and the pixel area corresponding to blue is arranged at the end of the display area DA, the dummy element 148 of the non-display area NDA adjacent to the pixel area PA corresponding to blue may include the same material as that of the element covering the pixel area PA corresponding to red.

[0096] According to one or more embodiments of the present disclosure, by including the dummy element 148 arranged in the non-display area NDA, the color panel 100 can prevent (or reduce) degradation of each element (e.g., the third element 146 adjacent to the dummy element 148) in the color conversion layer 140 covering the pixel area PA, and can minimize (or reduce) stains caused by the elements in the display area DA.

[0097] In the case where dummy components are not included (e.g. Figure 2A In the color panel of the related art (shown in FIG. 1 ), in the formation of the color conversion layer of the color panel, the dummy element 148 is arranged at the edge of the display area (for example, Figure 2A The outline of the element at the location where the third element 146 is arranged (shown in FIG. 1 ) may have a different outline from that of the element arranged in the central portion of the display area (eg, Figure 2A In this case, defects may occur during the process of forming a cover layer on the color conversion layer, and the defects may cause degradation of the components provided in the color panel. According to one or more embodiments of the present disclosure, the color panel 100 may include a dummy element 148 to improve reliability problems caused by the above-mentioned degradation.

[0098] The light shielding member 130 may be located in the non-display area NDA and may be located between any two of the pixel areas (e.g., PA1, PA2, and PA3) of the display area DA. The light shielding member 130 may be interposed between the substrate 110 and the color conversion layer 140. The light shielding member 130 may include, for example, a black matrix, a black pigment, a metal material, and / or the like. In some embodiments, the light shielding member 130 may include a material having a reflective property.

[0099] The color filter layer 120 may be interposed between the substrate 110 and the color conversion layer 140, and may include color filters 122, 124, and 126 that selectively transmit light of a specific wavelength band. The color filters 122, 124, and 126 may be positioned to correspond to (or correspond to) a plurality of pixel areas PA (e.g., PA1, PA2, and PA3) provided in the display area DA. For example, Figure 2A As shown in FIG. 1 , color filters 122 , 124 , and 126 positioned to correspond to the plurality of pixel areas PA1 , PA2 , and PA3 , respectively, may be spaced apart from one another with a light blocking member 130 therebetween.

[0100] The color filter layer 120 may include a first color filter 122 covering the first pixel area PA1 , a second color filter 124 covering the second pixel area PA2 , and a third color filter 126 covering the third pixel area PA3 .
