Each of the first pixel region PXA-R, the second pixel region PXA-G, and the third pixel region PXA-B may have different polygonal shapes such as a rhombus shape or a pentagonal shape on a plane.

[0092] Reference Figure 3b , a cross section corresponding to the driving transistor TD and the light emitting element OLED is shown as an example. A predetermined gap GP may be defined between the first display substrate 100 and the second display substrate 200. In the present embodiment, the gap GP is described as an empty space, but in an embodiment of the present invention, a predetermined material may be filled into the gap GP.

The circuit element layer DP-CL may be formed by a process of forming an insulator, a semiconductor layer, and a conductive layer by coating or deposition, and a process of patterning the insulator, the semiconductor layer, and the conductive layer by a photolithography process.

[0095] In this embodiment, the circuit element layer DP-CL may include a buffer layer BFL, a first insulating layer 10, a second insulating layer 20, and a third insulating layer 30. For example, each of the first insulating layer 10 and the second insulating layer 20 may be an inorganic layer, and the third insulating layer 30 may be an organic layer.

In this embodiment, the display element layer DP-OLED may include an organic light emitting diode as a light emitting diode. The display element layer DP-OLED includes a pixel defining layer PDL. For example, the pixel defining layer PDL may be an organic layer.

[0098] The first electrode AE ​​is disposed on the third insulating layer 30. The first electrode AE ​​is directly or indirectly connected to the driving transistor TD. Figure 3b The connection structure between the first electrode AE ​​and the driving transistor TD is not shown in the figure. The emission opening OP is defined in the pixel defining layer PDL. The emission opening OP of the pixel defining layer PDL exposes at least a portion of the first electrode AE. In the first display substrate 100, the emission opening OP defines an emission area LA corresponding to the first pixel area PXA-R. Here, "corresponding" means overlapping and is not limited to the same area. The first display substrate 100 has an emission area LA and a non-emission area NLA, and the emission area LA and the non-emission area NLA correspond to each other.

The laminated structure of the light emitting layer EML is not particularly limited, and may have various structures referred to as tandem structures.

[0102] The electronic control layer ECL may include an electron transport layer and may also include an electron injection layer. The light-emitting layer EML may be commonly arranged in the first pixel region PXA-R, the second pixel region PXA-G, and the third pixel region PXA-B, or may be individually arranged. Individually arranged means that the light-emitting layer EML is separated for each of the first pixel region PXA-R, the second pixel region PXA-G, and the third pixel region PXA-B. The second electrode CE is arranged on the electronic control layer ECL. The second electrode CE may be commonly arranged in the first pixel region PXA-R, the second pixel region PXA-G, and the third pixel region PXA-B.

[0104] The first display substrate 100 may include Figure 3aThe first display element, the second display element, and the third display element corresponding to the first pixel region PXA-R, the second pixel region PXA-G, and the third pixel region PXA-B shown in FIG. The first display element, the second display element, and the third display element may have the same laminated structure as each other, and may also have the same laminated structure as each other. Figure 3b The light-emitting element OLED has the same laminate structure.

[0105] like Figure 3b As shown in FIG. 1 , the second display substrate 200 includes a second base substrate BS2, color filters CF-R and CF-B disposed on a bottom surface (or “one surface”) BS2-LS of the second base substrate BS2, a partition wall BW disposed below the color filter, and a first color control pattern CCF-R. The top surface BS2-US of the second base substrate BS2 is connected to the Figure 1b corresponds to the outer surface 200 -OS of the second display substrate 200 shown in FIG.

[0106] In addition, the second display substrate 200 may further include at least one inorganic layer. At least one inorganic layer ENL1 and ENL2 may be further provided. At least one inorganic layer ENL1 and ENL2 may include at least one of silicon oxide, silicon nitride, and silicon oxynitride. In the present embodiment, two inorganic layers ENL1 and ENL2 are exemplarily shown. Each of the inorganic layers ENL1 and ENL2 has a function of a sealing layer in terms of durability of the second display substrate 200 and a function of a low refractive index film in terms of an emission path.

[0107] The second base substrate BS2 may include a synthetic resin substrate or a glass substrate. Each of the color filters CF-R and CF-B and the first color control pattern CCF-R includes a plurality of groups corresponding to the pixel regions PXA-R, PXA-R, and PXA-B. Each of the color filters CF-R and CF-B and the first color control pattern CCF-R includes three groups corresponding to the first pixel region PXA-R, the second pixel region PXA-G, and the third pixel region PXA-B.

[0108] The first color filter CF-R, the second color filter CF-G and the third color filter CF-B reduce the reflectivity of external light. Each of the first to third color filters transmits light with a specific wavelength range and blocks light with a corresponding wavelength range. The first color filter CF-R, the second color filter CF-G and the third color filter CF-B include a matrix resin and a dye and / or pigment dispersed in the matrix resin. The matrix resin can be a medium in which a dye and / or pigment is dispersed. Generally, the matrix resin can include various resin components referred to as adhesives. In the present embodiment, the first color filter can be a red color filter, the second color filter can be a green color filter, and the third color filter can be a blue color filter.

[0109] The first color control pattern CCF-R, the second color control pattern CCF-G (see Figure 4a ) and the third color control pattern CCF-B (see Figure 4a ) changes the optical properties of the source light. The first color control pattern and the second color control pattern can generate light with different colors after absorbing the source light generated by the light emitting element OLED. The third color control pattern can transmit and scatter a portion of the incident source light.

[0110] The first color control pattern and the second color control pattern may include a base resin and quantum dots mixed (or dispersed) in the base resin. In the present embodiment, the first color control pattern and the second color control pattern may be defined as a quantum dot layer and include different quantum dots. The base resin may be a medium in which quantum dots are dispersed. Generally, the base resin may include various resin components referred to as adhesives. However, embodiments of the present invention are not limited thereto. In this specification, a medium capable of dispersing quantum dots may be referred to as a base resin, regardless of its name, additional other functions, constituent materials, etc. The base resin may be a polymer resin. For example, the base resin may include an acrylic resin, a polyurethane resin, a silicone resin, and an epoxy resin. The base resin may be a transparent resin.

[0111] Quantum dots can be particles that convert the wavelength of incident light. Each of the quantum dots can be a material with a crystal structure of a few nanometers in size. The quantum dots can be composed of hundreds to thousands of atoms to provide a quantum confinement effect in which the energy band gap increases due to the small size. When light with a wavelength greater in energy than the energy of the band gap is incident on the quantum dots, the quantum dots can absorb the light and thus be in an excited state to emit light with a specific wavelength, thereby becoming a ground state. The emitted light has a wavelength corresponding to the band gap. When the size and composition of the quantum dots are adjusted, the luminescence characteristics due to the quantum confinement effect can be adjusted.

[0112] The quantum dots may be selected from the group consisting of Group II-VI compounds, Group III-V compounds, Group IV-VI compounds, Group IV elements, Group IV compounds, and combinations thereof.

[0113] The II-VI compound may be selected from a binary compound, a ternary compound, and a quaternary compound, the binary compound being selected from the group consisting of CdSe, CdTe, CdS, ZnS, ZnSe, ZnTe, ZnO, HgS, HgSe, HgTe, MgSe, MgS, and combinations thereof, the ternary compound being selected from the group consisting of CdSeS, CdSeTe, CdSTe, ZnSeS, ZnSeTe, ZnSTe, HgSeS, HgSeTe, HgSTe, Cd ZnS, CdZnSe, CdZnTe, CdHgS, CdHgSe, CdHgTe, HgZnS, HgZnSe, HgZnTe, MgZnSe, MgZnS and combinations thereof; and the quaternary compound is selected from the group consisting of HgZnTeS, CdZnSeS, CdZnSeTe, CdZnSTe, CdHgSeS, CdHgSeTe, CdHgSTe, HgZnSeS, HgZnSeTe and combinations thereof.

[0115] The III-V compound may be selected from a binary compound, a ternary compound, and a quaternary compound, the binary compound being selected from the group consisting of GaN, GaP, GaAs, GaSb, AlN, AlP, AlAs, AlSb, InN, InP, InAs, InSb, and combinations thereof, the ternary compound being selected from the group consisting of GaNP, GaNAs, GaNSb, GaPAs, GaPSb, AlNP, AlNAs, AlNSb, AlPAs, AlPSb, InGaP, InAlP, InNP, InNAs, InNSb, InPAs, InPSb, and combinations thereof, the quaternary compound being selected from the group consisting of GaAlNAs, GaAlNSb, GaAlPAs, GaAlPSb, GaInNP, GaInNAs, GaInNSb, GaInPAs, GaInPSb, InAlNP, InAlNAs, InAlNSb, InAlPAs, InAlPSb, and combinations thereof. The III-V compound may also include a Group II metal. For example, InZnP or the like may be selected as the III-II-V group compound.

[0116] The IV-VI group compound may be selected from a binary compound, a ternary compound and a quaternary compound, the binary compound being selected from the group consisting of SnS, SnSe, SnTe, PbS, PbSe, PbTe and combinations thereof, the ternary compound being selected from the group consisting of SnSeS, SnSeTe, SnSTe, PbSeS, PbSeTe, PbSTe, SnPbS, SnPbSe, SnPbTe and combinations thereof, the quaternary compound being selected from the group consisting of SnPbSSe, SnPbSeTe, SnPbSTe and combinations thereof. The IV group element may be selected from the group consisting of Si, Ge and combinations thereof. The IV group compound may be a binary compound selected from the group consisting of SiC, SiGe and combinations thereof.

[0117] Here, the binary compound, the ternary compound, and the quaternary compound may exist as particles at a uniform concentration, or may exist as particles in a state in which the concentration distribution is different.

[0118] The quantum dot may have a core / shell structure including a shell surrounding a core. Alternatively, the quantum dot may 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 element present in the shell has a concentration that gradually decreases toward the core.

[0119] Each of the quantum dots may have a particle size of nanometers. The quantum dots may have a full width at half maximum (FWHM) of an emission wavelength spectrum of about 45 nm or less (preferably about 40 nm or less, more preferably about 30 nm or less). Within this range, color purity and color reproducibility may be improved. In addition, light emitted by the quantum dots may be emitted in all directions to improve the optical viewing angle.

[0120] In addition, each of the quantum dots has a shape commonly used in the art, and there is no particular limitation on the shape. However, the quantum dots may have a spherical shape, a pyramid shape, a multi-arm shape, a cubic nanoparticle shape, a nanotube shape, a nanowire shape, a nanofiber shape, or a nanoplate shape, etc. The quantum dots may adjust the color of the emitted light according to their size. Therefore, the quantum dots may emit light of various colors such as red, green, and blue.

[0121] In this embodiment, the first color control pattern may be a red quantum dot pattern that generates red light after absorbing the source light, and the second color control pattern may be a green quantum dot pattern that generates green light after absorbing the source light.

[0122] Figure 3bThe first color filter CF-R, the third color filter CF-B and the first color control pattern CCF-R are shown. The third color filter CF-B is disposed in the peripheral area NPXA, and the first pixel opening B-OP (hereinafter, referred to as the first opening or the first group of openings) defining the first pixel area PXA-R is defined in the third color filter CF-B. Figure 4c As described, the first pixel opening B-OP defining the second pixel region PXA-G may also be formed in the third color filter CF-B. In this embodiment, the third color filter CF-B may correspond to a dividing pattern that separates the first pixel region PXA-R from other pixel regions.

[0123] The first color filter CF-R overlaps the first opening B-OP and is disposed under the third color filter CF-B in the peripheral area NPXA.

[0124] The first encapsulation layer (or referred to as "first inorganic layer") ENL1 is disposed under the first color filter CF-R and the third color filter CF-B. The first encapsulation layer ENL1 seals the first color filter CF-R and the third color filter CF-B. The first encapsulation layer ENL1 may be commonly disposed in the first pixel region PXA-R, the second pixel region PXA-G, and the third pixel region PXA-B (see Figure 3a )middle.

[0125] The partition wall BW is disposed under the first encapsulation layer ENL1. In an embodiment, the partition wall BW may be a black matrix as a pattern having black. In an embodiment, the partition wall BW may include a black colorant (or a black component). The black component may include a black dye and a black pigment. The black component may include carbon black, a metal (such as chromium) or an oxide thereof.

[0126] The partition wall BW corresponds to another dividing pattern that is different from the third color filter CF-B. In the present embodiment, the third color filter CF-B can be defined as a first dividing pattern, and the partition wall BW can be defined as a second dividing pattern. The opening BW-OP (hereinafter referred to as the common opening) is defined in the second dividing pattern BW. The first color control pattern CCF-R overlapping with the common opening BW-OP is arranged under the first encapsulation layer ENL1. The second encapsulation layer (or referred to as the "second inorganic layer") ENL2 seals the second dividing pattern BW and the first color control pattern CCF-R. The second encapsulation layer ENL2 can be commonly arranged in the first pixel area PXA-R, the second pixel area PXA-G and the third pixel area PXA-B. As Figure 3b As shown in , the width of the common opening BW-OP in the first direction DR1 may be greater than the width of the first opening B-OP. Although not separately shown, the size of the common opening BW-OP may be greater than the size of the first opening B-OP on a plane.

[0127] Figure 4a is an enlarged plan view of a display area DA according to an embodiment of the present invention. Figure 4b It is along Figure 4a A cross-sectional view taken along line II-II'. Figure 4c to Figure 4f is a plan view illustrating a method for manufacturing the second display substrate 200 according to an embodiment of the present invention. Figure 4g 2 is a cross-sectional view illustrating one process in a method for manufacturing the second display substrate 200 according to an embodiment of the present invention.

[0128] Figure 4b The inverted state in the third direction DR3 is shown. Figure 3b That is, based on the bottom surface BS2-LS of the second base substrate BS2, Figure 4b Although not shown separately, in addition to the type of color filter and color control pattern, Figure 4a The cross section corresponding to line III-III' and Figure 4a The section corresponding to line IV-IV' is Figure 4b The cross-section shown in is substantially the same. In addition, the bottom surface BS2-LS based on the second base substrate BS2 shows Figure 4c to Figure 4f .

[0129] exist Figure 4a In FIG. 1 , two unit pixel rows PXL-U1 and PXL-U2 are shown as the center. For ease of description, the upper unit pixel row PXL-U1 is defined as a first unit pixel row PXL-U1, and the lower unit pixel row PXL-U2 is defined as a second unit pixel row PXL-U2.

[0130] like Figure 4a and Figure 4b As shown in the figure, the first dividing pattern CF-B defines the first pixel area PXA-R of the first unit pixel row PXL-U1 and the first pixel area PXA-R of the second unit pixel row PXL-U2. For the convenience of description, a pixel row set in the first unit pixel row PXL-U1 is defined as the first pixel row PXL-11, and a pixel row set in the second unit pixel row PXL-U2 is defined as the second pixel row PXL-12. In addition, another pixel row set in the first unit pixel row PXL-U1 is defined as the third pixel row PXL-21, and another pixel row set in the second unit pixel row PXL-U2 is defined as the fourth pixel row PXL-22.

[0131] The first color filter CF-R overlaps each of the first pixel area PXA-R of the first pixel line PXL-11 and the first pixel area PXA-R of the second pixel line PXL-12. The second dividing pattern BW is disposed on the first inorganic layer ENL1 and overlaps the peripheral area NPXA.

[0132] Reference Figure 3b Description of the common opening BW-OP and Figure 4a The first common opening BW-OP1 corresponds to the first pixel region PXA-R of the first pixel row PXL-11 and the first pixel region PXA-R of the second pixel row PXL-12. The first pixel region PXA-R of the first pixel row PXL-11 and the first pixel region PXA-R of the second pixel row PXL-12 are arranged in the first common opening BW-OP1.

[0133] The second dividing pattern BW overlaps the non-pixel region NPXA disposed outside the two first pixel regions PXA-R, and does not overlap the non-pixel region NPXA disposed between the two first pixel regions PXA-R. In a plane, the second dividing pattern BW surrounds the two first pixel regions PXA-R.

[0134] The first color control pattern CCF-R is disposed to overlap the first common opening BW-OP1. The first color control pattern CCF-R overlaps the two first pixel regions PXA-R. The first color control pattern CCF-R also overlaps the non-pixel region NPXA disposed between the two first pixel regions PXA-R.

[0135] The first dividing pattern CF-B divides the first common opening BW-OP1 into two first pixel regions PXA-R. A portion of the first dividing pattern CF-B is disposed between the first pixel region PXA-R of the first pixel row PXL-11 and the first pixel region PXA-R of the second pixel row PXL-12. The first color control pattern CCF-R overlaps a portion of the first dividing pattern CF-B between the first pixel region PXA-R of the first pixel row PXL-11 and the first pixel region PXA-R of the second pixel row PXL-12.

[0136] The two first pixel regions PXA-R are associated with two different pixels PX (see Figure 2 ). When source light is incident on any one of the two first pixel regions PXA-R, the first dividing pattern CF-B blocks the source light so that the source light does not enter the other first pixel region PXA-R. That is, the first dividing pattern CF-B can prevent crosstalk between two different pixels PX.

[0137] Reference Figure 4c First, a first dividing pattern CF-B is formed on one surface BS2-LS of the second base substrate BS2. A first opening B-OP defining the first pixel region PXA-R and the second pixel region PXA-G is formed in the first dividing pattern CF-B.

[0138] The first dividing pattern CF-B may be formed through a general color filter patterning process. After forming a preliminary color filter layer, the first opening B-OP is formed in the preliminary color filter layer through an optical process.

[0139] In the present embodiment, since the first dividing pattern CF-B is substantially a blue color filter CF-B, the first dividing pattern CF-B overlaps the third pixel region PXA-B. Figure 4c In the figure, since the third pixel region PXA-B is a virtual region, it is indicated by a dotted line. In addition, the first dividing pattern CF-B is disposed in the non-pixel region NPXA.

[0140] Next, if Figure 4d As shown in the figure, a first color filter CF-R is formed on one surface BS2-LS of the second base substrate BS2. The first color filter CF-R is disposed on the first dividing pattern CF-B. The first color filter CF-R overlaps a portion of the non-pixel area NPXA and the first pixel area PXA-R. The first color filter CF-R does not overlap the second pixel area PXA-G. A region CF-RB having a predetermined shape to define a portion of the third pixel area PXA-B is formed in the first color filter CF-R.

[0141] Next, if Figure 4e As shown in the figure, a second color filter CF-G is formed on one surface BS2-LS of the second base substrate BS2. The second color filter CF-G is disposed on the first dividing pattern CF-B. The second color filter CF-G overlaps the second pixel region PXA-G and another portion of the non-pixel region NPXA on which the first color filter CF-R is not formed. A region CF-GB having a predetermined shape to define a portion of the third pixel region PXA-B is formed in the second color filter CF-G.

[0142] Figure 4d The partial area CF-RB of the first color filter CF-R and Figure 4e The partial region CF-GB of the second color filter CF-G may form a second pixel opening RG-OP (hereinafter, referred to as a second opening) that substantially defines the third pixel region PXA-B. The third pixel region PXA-B is a region in which both the first color filter CF-R and the second color filter CF-G are not disposed, and is defined by an edge of a portion of the first color filter CF-R and an edge of a portion of the second color filter CF-G.

[0143] Despite Figure 4e The first color filter CF-R and the second color filter CF-G are shown as not overlapping, but the first color filter CF-R and the second color filter CF-G may partially overlap each other in the non-pixel area NPXA. Thereafter, the inorganic material deposition process may be used to form Figure 4b The first inorganic layer ENL1.

[0144] Next, if Figure 4f As shown in , a second dividing pattern BW overlapping the non-pixel area NPXA is formed. A plurality of common openings BW-OP1, BW-OP2, and BW-OP3 are defined in the second dividing pattern BW. The common opening BW-OP1 corresponding to the two first pixel areas PXA-R may be defined as a first common opening, the common opening BW-OP2 corresponding to the two second pixel areas PXA-G may be defined as a second common opening, and the common opening BW-OP3 corresponding to the two third pixel areas PXA-B may be defined as a third common opening. After forming the preliminary separation layer, a plurality of common openings BW-OP1, BW-OP2, and BW-OP3 may be formed in the preliminary separation layer by an optical process.

[0145] Next, after forming the second dividing pattern BW on the first inorganic layer ENL1, a color control pattern may be formed in the plurality of common openings BW-OP1, BW-OP2, BW-OP3. The first color control pattern, the second color control pattern, and the third color control pattern corresponding to the first common opening BW-OP1, the second common opening BW-OP2, and the third common opening BW-OP3, respectively, may be sequentially formed.

[0146] Figure 4g It is along Figure 4f The cross-sectional view taken along the line V-V' of Figure 4g Description used to form Figure 4b The method of the first color control pattern CCF-R. Figure 4g As shown in FIG. , a solution CCF-L (hereinafter, referred to as a pattern solution) can be used to form Figure 4a and Figure 4b The pattern solution used to form the first color control pattern CCF-R may be a quantum dot solution. Figure 4a The pattern solution of the second color control pattern CCF-G may be a quantum dot solution, and the pattern solution for forming the third color control pattern CCF-B may be a scattering particle solution.

[0147] For example, in an inkjet process, the pattern solution CCF-L is provided to the first common opening BW-OP1 with an inkjet head 1H. In order to accommodate a sufficient amount of the pattern solution CCF-L, the second dividing pattern BW has a thickness greater than that of the first dividing pattern CF-B. The pattern solution CCF-L may include silver quantum dot particles. The quantum dot particles may not be added to the pattern solution CCF-L for forming the third color control pattern. The pattern solution CCF-L may also include silver scattering particles and a surfactant. In addition, the pattern solution CCF-L may also include epoxy resin or epoxy acrylate. For example, the pattern solution CCF-L may also include methyl methacrylate (MMA) or polymethyl methacrylate (PMMA). The pattern solution CCF-L may also include a solvent for the inkjet process.

[0148] In a liquid phase process such as an inkjet process, a predetermined amount or more of solution must be provided to form a color control pattern having a predetermined thickness or thicker. When the volume of the space defined by the openings formed in the second dividing pattern BW is larger than the reference volume, the process conditions of the liquid phase process are satisfied. Here, the reference volume means the minimum volume for preventing the solution from overflowing into an adjacent opening when a predetermined amount of solution is provided to one opening.

[0149] One first common opening BW-OP1 may correspond to two first pixel regions PXA-R to provide sufficient space for forming a color control pattern. That is, the second dividing pattern BW according to the present embodiment may easily satisfy the liquid phase process conditions. In addition, the thickness of the second dividing pattern BW may be reduced within a range in which the liquid phase process conditions are satisfied.

[0150] In addition, the difference in surface area between the two first pixel regions PXA-R and the first common opening BW-OP1 can be minimized. In other words, it is not necessary to intentionally (or deliberately) make the opening size of the opening formed in the second dividing pattern BW larger than the opening size of the corresponding pixel region in order to meet the liquid phase process conditions. This is because the first common opening BW-OP1 provides sufficient capacity. When the surface area of ​​the non-pixel area NPXA not covered by the second dividing pattern BW is reduced, the reflectivity of external light is reduced.

[0151] There is no need to control the shape of the first common opening BW-OP1 to intentionally increase the size of the opening. Since the shape of the first common opening BW-OP1 is simplified, process errors are reduced.

[0152] Thereafter, an inorganic material deposition process can be used to form Figure 4b Thereafter, the completed second display substrate 200 may be bonded to the first display substrate 100 .

[0153] Figure 5a is a plan view of a display area according to an embodiment of the present invention. Figure 5b is a cross-sectional view of a display region according to an embodiment of the present invention. Figure 5c is a plan view of a display area according to an embodiment of the present invention.

[0154] Figure 5a and Figure 4e correspond, Figure 5b and Figure 4b correspond, Figure 5c and Figure 4c Corresponding. In the following, the reference Figure 1a to Figure 4g The construction described is the same as the detailed description of the construction.

[0155] Reference Figure 5a , in the periphery of the third pixel region PXA-B (i.e., in the periphery of the second opening RG-OP), the surface area occupied by the first color filter CF-R is larger than the surface area occupied by the second color filter CF-G. Because the first color filter CF-R transmits light having a longer wavelength than the wavelength of light transmitted by the second color filter CF-G, the blocking effect on the source light (or blue light) having a shorter wavelength is greater than the blocking effect of the second color filter CF-G.
