[0064] The normal direction of the display surface DP-IS, that is, the thickness direction of the display panel DP indicates the third direction DR3. In this specification, the meaning of "when viewed on a plane or on a plane" may refer to the situation of viewing in the third direction DR3. The front (or top) and back (or bottom) of each layer or unit described below are distinguished by the third direction DR3. However, the directions designated by the first direction DR1, the second direction DR2, and the third direction DR3 are relative concepts and can be converted into other directions, such as the opposite direction.

The cell gap GP may be maintained by an adhesive layer SLM that combines the upper display substrate 200 and the lower display substrate 100. As an example, the adhesive layer SLM may include an organic adhesive component or an inorganic adhesive component.

[0067] Figure 3 is a top view of a display panel according to an embodiment of the present disclosure.

[0068] Reference Figure 3 , showing the arrangement relationship of the signal lines GL1 ˜GLn, DL1 ˜DLm and the pixels PX11 ˜PXnm on a plane. The signal lines GL1 ˜GLn, DL1 ˜DLm may include a plurality of gate lines GL1 ˜GLn and a plurality of data lines DL1 ˜DLm.

[0069] Each of the pixels PX11 to PXnm is connected to a corresponding gate line among the plurality of gate lines GL1 to GLn and a corresponding data line among the plurality of data lines DL1 to DLm. Each of the pixels PX11 to PXnm may include a pixel driving circuit and a display element. According to the configuration of the pixel driving circuit, the display panel DP may have more signal lines.

[0070] The pixels PX11 to PXnm may be arranged in a matrix shape, but are not limited thereto. The pixels PX11 to PXnm may be arranged in a corrugated tile shape. The pixels PX11 to PXnm may be arranged in a diamond shape.

[0071] The gate driving circuit GDC may be arranged in the non-display area NDA and may be integrated in the display panel DP by using an oxide silicon gate driver circuit (OSG) or an amorphous silicon gate driver circuit (ASG) process.

[0072] Figure 4A is a top view of a pixel area included in a display area of ​​a display panel according to an embodiment of the present disclosure. Figure 4B is a cross-sectional view of a display panel illustrating a portion of a pixel region according to an embodiment of the present disclosure.

[0073] Figure 4A yes Figure 1 FIG. 1 is an enlarged view of a portion of the display area DA shown in FIG. The display area DA may include a plurality of pixel areas PXA and light shielding areas NPXA adjacent thereto. For convenience of explanation, Figure 4A , shown with three pixel areas PXA-R, PXA-G, and PXA-B as the center. Figure 4A The three pixel regions PXA-R, PXA-G, and PXA-B shown in FIG. 1 may be repeatedly arranged in the entire display area DA.

[0074] The light shielding area NPXA is arranged around the first pixel area PXA-R, the second pixel area PXA-G, and the third pixel area PXA-B. The first pixel area PXA-R, the second pixel area PXA-G, the third pixel area PXA-B, and the light shielding area NPXA can be substantially defined on the upper display substrate 200. In this specification, the pixel area means that light is blocked by using Figure 1 The area actually emitted to the outside is the display surface DP-IS described above.

[0075] pass Figure 4AThe first pixel region PXA-R, the second pixel region PXA-G, and the third pixel region PXA-B are exemplarily shown as having the same area on a plane, but the present invention is not limited thereto. The first pixel region PXA-R, the second pixel region PXA-G, and the third pixel region PXA-B may have different areas from each other, or at least two or more areas may be different from each other.

[0076] In addition, the first pixel region PXA-R, the second pixel region PXA-G, and the third pixel region PXA-B are shown as rectangular quadrilaterals having rounded corners on a plane, but the present invention is not limited thereto. The first pixel region PXA-R, the second pixel region PXA-G, and the third pixel region PXA-B may also have other polygonal shapes on a plane, or may have a regular polygonal shape with rounded corners.

[0077] One of the first pixel area PXA-R, the second pixel area PXA-G, and the third pixel area PXA-B provides the user with light of a first color having a band of a first color, another provides light of a second color having a band of a second color different from the first color, and the remaining other provides light of a third color having a band of a third color different from the first color and the second color.

[0078] According to an embodiment of the present disclosure, the first pixel region PXA-R may provide red light, the second pixel region PXA-G may provide green light, and the third pixel region PXA-B may provide blue light. According to an embodiment of the present disclosure, the primary color light may be blue light as the first color light. The primary color light may be generated from a light source such as a backlight unit, or may be generated from a display element such as a light emitting diode.

[0079] The light shielding area NPXA sets the boundary of the first pixel area PXA-R, the second pixel area PXA-G, and the third pixel area PXA-B to prevent color mixing between the first pixel area PXA-R, the second pixel area PXA-G, and the third pixel area PXA-B. In addition, the light shielding area NPXA blocks the primary color light so that the primary color light is not provided to the user.

[0080] Figure 4B The cross section of the display panel DP corresponding to the second pixel region PXA-G and the cross section corresponding to the driving transistor TD and the light emitting element OLED are exemplarily shown. Figure 4B The upper display substrate 200 is briefly shown in FIG.

[0081] Reference Figure 4B , the lower display substrate 100 includes a first base substrate BS1, a circuit element layer DP-CL arranged on the first base substrate BS1, and a display element layer DP-OLED arranged on the circuit element layer DP-CL.

[0082] The first base substrate BS1 may include a synthetic resin substrate or a glass substrate. The circuit element layer DP-CL includes at least one insulating layer and circuit elements. The circuit elements include signal lines, pixel driving circuits, etc. The circuit element layer DP-CL may be formed by a process for forming an insulating layer, a semiconductor layer, and a conductive layer based on coating, evaporation, etc., and a patterning process for an insulating layer, a semiconductor layer, and a conductive layer based on a photolithography process.

[0083] In the present embodiment, the circuit element layer DP-CL may include a buffer film BFL, a first insulating layer 10, a second insulating layer 20, and a third insulating layer 30. As an example, the first insulating layer 10 and the second insulating layer 20 may be inorganic films, and the third insulating layer 30 may be an organic film. However, this is not limited thereto, and the first insulating layer 10 and the second insulating layer 20 may be a mixed layer of an inorganic film and an organic film.

[0084] Figure 4B Schematically shows the arrangement relationship of the semiconductor pattern OSP, the control electrode GE, the input electrode DE, and the output electrode SE constituting the drive transistor TD, and also exemplarily shows the first through hole CH1, the second through hole CH2, and the third through hole CH3.

[0085] The display element layer DP-OLED includes a light-emitting element OLED as a display element. The light-emitting element OLED can generate the above-mentioned primary color light. The light-emitting element OLED includes a first electrode AE, a second electrode CE and a light-emitting layer ENL arranged therebetween. In this embodiment, the light-emitting element OLED may include an organic light-emitting diode. The display element layer DP-OLED includes a pixel definition film PDL. For example, the pixel definition film PDL may be an organic layer.

[0086] The first electrode AE ​​is arranged on the third insulating layer 30. The first electrode AE ​​is connected to the output electrode SE through the third through hole CH3 penetrating the third insulating layer 30. A light-emitting opening portion OP is defined on the pixel definition film PDL. The light-emitting opening portion OP of the pixel definition film PDL exposes at least a portion of the first electrode AE. According to the present disclosure, the light-emitting opening portion OP may be defined as a light-emitting region where light is actually emitted from the light-emitting element OLED. That is, a plurality of light-emitting regions may be provided, and each corresponds to a pixel region.

[0087] The hole control layer HCL, the light emitting layer ENL, and the electron control layer ECL may be disposed on the first electrode AE ​​and the pixel definition film PDL. The hole control layer HCL, the light emitting layer ENL, and the electron control layer ECL may be disposed on the first pixel region PXA-R, the second pixel region PXA-G, and the third pixel region PXA-B (refer to Figure 4A ).

[0088] The hole control layer HCL includes a hole transport layer and may further include a hole injection layer. The light emitting layer ENL may generate blue light. The blue light may include a wavelength of 410nm to 480nm. The emission spectrum of the blue light may have a maximum peak within 440nm to 460nm. The electron control layer ECL includes an electron transport layer and may further include an electron injection layer. The light emitting layer ENL may have a multilayer structure or a single layer structure.

[0089] A second electrode CE is arranged on the electronic control layer ECL. The second electrode CE may be arranged in the first pixel region PXA-R, the second pixel region PXA-G, and the third pixel region PXA-B. The second electrode CE has a larger area than the first electrode AE. A cover layer CL for protecting the second electrode CE may be further arranged on the second electrode CE. The cover layer CL may include an organic substance or an inorganic substance. In one embodiment, the cover layer CL may be omitted.

[0090] Although not shown separately, the lower display substrate 100 may include a Figure 4A The first to third light-emitting elements of the first pixel region PXA-R, the second pixel region PXA-G, and the third pixel region PXA-B shown in FIG. The stacked structures of the first to third light-emitting elements are the same as each other and may have Figure 3 The stacked structure of the light-emitting element OLED is shown in FIG.

[0091] Figure 5 is a top view of a display panel according to an embodiment of the present disclosure. Figure 6 According to an embodiment of the present disclosure, Figure 5 2 is a cross-sectional view taken along line II′ shown in FIG. Fig. 7A Is magnification Figure 6 An enlarged view of the AA region is shown in FIG. Figure 7B is a graph showing the wavelength range of colors. Figure 8 It is briefly shown Figure 6 Graph of the optical characteristics of the light control layer shown in FIG.

[0092] Reference Figure 5 , in order to pass Figure 4B The light emitted by the light emitting element OLED is not observed through the non-display area NDA of the display panel DP, and the upper display substrate 200 may include a light shielding layer BY overlapping the non-display area NDA. As an example, the light shielding layer BY is closer to the display area DA than the adhesive layer SLM arranged between the upper display substrate 200 and the lower display substrate 100 in a plane.

[0093] The adhesive layer SLM may overlap the non-display area NDA in a plane and surround the display area DA. The adhesive layer SLM may be arranged adjacent to the edge of the display panel DP and arranged between the upper display substrate 200 and the lower display substrate 100. The light shielding layer BY according to an embodiment of the present disclosure may be provided in black.

[0094] On the other hand, after the adhesive layer SLM is disposed between the upper display substrate 200 and the lower display substrate 100 , ultraviolet rays may be irradiated to the adhesive layer SLM for hardening. In this case, the ultraviolet rays irradiated to the adhesive layer SLM may be incident through the upper display substrate 200 .

[0095] According to an embodiment of the present disclosure, the light shielding layer BY may partially overlap the non-display area NDA instead of entirely overlapping the non-display area NDA. For example, the light shielding layer BY may not overlap at least a portion of the adhesive layer SLM. Therefore, ultraviolet rays incident through the upper display substrate 200 may irradiate the adhesive layer SLM.

[0096] However, external light may enter from the outside through an area of ​​the non-display area NDA of the upper display substrate 200 that does not overlap with the adhesive layer SLM. That is, the external light entering through the area is reflected from the inside of the display panel and retransmitted to the outside. As a result, the visibility of the display panel caused by the external light reflection is reduced.

[0097] According to an embodiment of the present disclosure, the upper display substrate 200 may include a filter layer FY covering the one area. The filter layer FY may be provided with other colors that allow ultraviolet rays to pass, unlike the light shielding layer BY that absorbs external ultraviolet rays. In addition, the filter layer FY may absorb light of a certain wavelength range in the wavelength range of external light incident from the outside.

[0098] As an example, Figure 5 As shown, the filter layer FY may entirely overlap the adhesive layer SLM to surround the display area DA in a plane. In this case, in a plane, the shortest distance from the display area DA to the outermost portion of the filter layer FY may be longer than the shortest distance from the display area DA to the outermost portion of the adhesive layer SLM.

[0099] As another example, on a plane, the shortest distance from the display area DA to the outermost portion of the filter layer FY and the shortest distance from the display area DA to the outermost portion of the adhesive layer SLM may be substantially the same.

[0100] Specifically, refer to Figure 6, the upper display substrate 200 includes a second base substrate BS2, a light shielding layer BY, a color filter layer CFY, a light control layer CCL, a first upper insulating layer LY, and a second upper insulating layer IY. Although not shown, in other embodiments of the present disclosure, when the display elements corresponding to the first pixel region PXA-R, the second pixel region PXA-G, and the third pixel region PXA-B generate light of different colors from each other, the light control layer CCL may be omitted.

[0101] The second base substrate BS2 may include a synthetic resin substrate or a glass substrate. The circuit element layer DP-CL includes at least one insulating layer and circuit elements. The circuit elements include signal lines, pixel driving circuits, etc. The circuit element layer DP-CL may be formed by a process for forming an insulating layer, a semiconductor layer, and a conductive layer based on coating, evaporation, etc., and a patterning process for an insulating layer, a semiconductor layer, and a conductive layer based on a photolithography process.

[0102] A light shielding layer BY and a color filter layer CFY divided by the light shielding layer BY may be disposed on the second base substrate BS2.

[0103] The light shielding layer BY includes a first portion BMa overlapping the display area DA and a second portion BMb overlapping the non-display area NDA. The first portion BMa of the light shielding layer BY corresponds to the Figure 4A Description of the shading area NPXA, Figure 5 The light shielding layer BY shown in corresponds to the second portion BMb.

[0104] The first color filter CF1, the second color filter CF2, and the third color filter CF3 may be arranged on the second base substrate BS2. According to an embodiment of the present disclosure, the first color filter CF1, the second color filter CF2, and the third color filter CF3 may be directly arranged on the second base substrate BS2. The first color filter CF1, the second color filter CF2, and the third color filter CF3 directly arranged under the second base substrate BS2 reduce the reflectivity of external light. This is because each of the first color filter CF1, the second color filter CF2, and the third color filter CF3 transmits light in a specific wavelength range and absorbs light outside the wavelength range.

[0105] The first color filter CF1 overlaps Figure 4A The first pixel region PXA-R shown in FIG. 1 can transmit light of a wavelength range corresponding to a second color and absorb light of a remaining wavelength range. As an example, the second color can be red.

[0106] The second color filter CF2 overlaps the second pixel region PXA-G and allows light of a wavelength range corresponding to a third color to pass through and absorbs light of a remaining wavelength range. As an example, the third color may be green.

[0107] The third color filter CF3 overlaps the third pixel region PXA-B and allows light of a wavelength range corresponding to the first color to pass through and absorbs light of a remaining wavelength range. As mentioned above, the first color light may be blue light as a primary color light.

[0108] According to the present disclosure, the first color filter CF1, the second color filter CF2, and the third color filter CF3 overlapping the display area DA may be divided by the first portion BMa of the light shielding layer BY. The second portion BMb of the light shielding layer BY may surround the color filter layer CFY on a plane.

[0109] The filter layer FY may cover at least a portion of the second portion BMb of the light shielding layer BY and be disposed on the second base substrate BS2. For example, the filter layer FY may be directly disposed on the second base substrate BS2 and cover at least a portion of the second portion BMb.

[0129] At this time, the binary compound, ternary compound or quaternary compound may be present in the particle at a uniform concentration, or may be present separately in the same particle in a state where the concentration distribution is partially different. In addition, there may be a core / shell structure in which one quantum dot surrounds other quantum dots.

[0136] Fig. 9A is a top view of a display panel according to another embodiment of the present disclosure. Fig. 9B According to another embodiment of the present disclosure, Fig. 9A A cross-sectional view taken along line II-II′ is shown in FIG. Fig.10 It is shown Fig. 9A and Fig. 9B A top view of the color filter shown in FIG.

[0137] Fig. 9A The display panel DPa shown in FIG. Figure 5 Compared with the display panel DP shown in FIG. 1 , only the configurations of the filter layer FY and the light shielding layer BY are changed, and the remaining configurations are substantially the same. Fig. 9A and Fig. 9B Description of it.

[0138] Reference Fig. 9A According to another embodiment of the present disclosure, the filter layer FYa may surround the display area DA in a plane and may not overlap with the adhesive layer SLM. The adhesive layer SLM may surround the filter layer FYa in a plane. Figure 5 The filter layer FY shown in FIG. 1 is a structure that overlaps with the adhesive layer SLM. On the contrary, Fig. 9A The filter layer FYa shown in FIG. 5 may be a structure that does not overlap with the adhesive layer SLM.

[0139] In addition, the filter layer FYa according to another embodiment of the present disclosure may be provided in red.

[0140] Specifically, refer to Fig. 9B The first color filter CF1, the second color filter CF2, and the third color filter CF3 of the color filter layer CFY may be disposed on the second base substrate BS2. According to one embodiment, the first color filter CF1, the second color filter CF2, and the third color filter CF3 are directly disposed on the second base substrate BS2.

[0141] According to an embodiment of the present disclosure, the refractive index of each of the first color filter CF1, the second color filter CF2, and the third color filter CF3 may be similar to the refractive index of the second base substrate BS2. As a result, external light coming from the outside may be incident on the first color filter CF1, the second color filter CF2, and the third color filter CF3 through the second base substrate BS2. Therefore, the external light reflection generated at the interface between the second base substrate BS2 and the first color filter CF1, the second color filter CF2, and the third color filter CF3 can be reduced.

[0142] In particular, the third color filter CF3 according to the present disclosure may be divided into a filter portion BP1 having a function of a color filter and a light shielding portion having a function of a light shielding pattern. The filter portion BP1 may overlap the third pixel region PXA-B. The light shielding portion includes a first light shielding portion BP2a overlapping the light shielding region NPXA and a second light shielding portion BP2b overlapping the non-display region NDA. As an example, the second light shielding portion BP2b may overlap the non-display region NDA as a whole and partially overlap the display region DA.

[0143] like Fig.10 As shown in FIG. 1 , after a blue organic layer is formed on one side of the second base substrate BS2, the organic layer is exposed and developed, thereby forming a third color filter CF3 having a first opening B-OP1 and a second opening B-OP2. That is, the filter portion BP1 and the first light shielding portion BP2a are provided in an integral shape. In addition, the second light shielding portion BP2b may also be formed by Fig.10 The filter portion BP1 and the first light shielding portion BP2a shown in FIG. 1 are provided in an integral shape by the same process.

[0144] Although not shown, the first color filter CF1 is arranged at the first opening portion B-OP1 defined by the third color filter CF3. On a plane, the first color filter CF1 may cover the first opening portion B-OP1 as a whole, and at least a portion thereof may be arranged on the first light shielding portion BP2a. The second color filter CF2 is arranged at the second opening portion B-OP2 defined by the third color filter CF3. On a plane, the second color filter CF2 may cover the second opening portion B-OP2 as a whole, and at least a portion thereof may be arranged on the first light shielding portion BP2a.

[0145] Refer again Fig. 9B According to another embodiment of the present disclosure, the filter layer FYa may overlap the non-display area NDA and be arranged on the second light shielding portion BP2b. In addition, as described above, the filter layer FYa may not overlap the adhesive layer SLM as a whole. However, it is not limited thereto, and the filter layer FYa may not overlap at least a portion of the adhesive layer SLM.

[0146] On the other hand, the second light shielding portion BP2b according to the present disclosure is provided as blue, which is the color of the third color filter CF3, so that external ultraviolet rays can pass through the second light shielding portion BP2b. In addition, the filter layer FYa does not overlap with the bonding layer SLM, so that ultraviolet rays incident from the outside through the second base substrate BS2 can be transmitted to the bonding layer SLM.

[0147] In addition, the filter layer FYa according to the present disclosure may be disposed as a whole in the remaining portion of the second light shielding portion BP2b except for the portion overlapping with the adhesive layer SLM. Therefore, the reflection of external light incident from the outside can be reduced, and the first color light emitted from the display element layer DP-OLED can be prevented from passing through the non-display area NDA to the outside.

[0148] Specifically, the light of the remaining wavelength range except the light of the blue wavelength range in the external light incident through the non-display area NDA of the second base substrate BS2 can be absorbed by the second light shielding portion BP2b. In addition, the light of the blue wavelength range passing through the second light shielding portion BP2b can be absorbed by the filter layer FYa which does not overlap with the adhesive layer SLM and has a wavelength range corresponding to the second color red. Therefore, the external light incident through the second base substrate BS2 is doubly blocked by the second light shielding portion BP2b and the filter layer FYa, so that the external light reflection can be reduced as a whole.

[0149] In addition, among the light emitted from the display element layer DP-OLED, the light transmitted to the non-display area NDA of the second base substrate BS2 can also be absorbed by the filter layer FYa. The first color light in the blue wavelength range emitted from the display element layer DP-OLED can be absorbed by the filter layer FYa that absorbs the light in the wavelength range other than the red wavelength range. Therefore, the overall visibility of the display panel DP can be improved.

[0150] Fig.11 is a cross-sectional view of a display panel according to another embodiment of the present disclosure.

[0151] Fig.11 The display panel DPb shown in FIG. Fig. 9B Compared with the display panel DPa shown in FIG. 1 , only the filter layer FYa and the second light shielding portion BP2b have changed in structure, and the remaining structure may be substantially the same. Therefore, for the convenience of description, the above description is omitted. Fig.11 Description of it.

[0152] Reference Fig.11 The second light shielding portion BP2b may not overlap the adhesive layer SLM and may be disposed on the second base substrate BS2. The filter layer FYb may entirely cover the second light shielding portion BP2b and may be disposed on the second base substrate BS2.

[0153] In addition, the filter layer FYb may be entirely overlapped with the non-display area NDA, and at least a portion of the filter layer FYb may be directly disposed on the second base substrate BS2. Ultraviolet rays incident through the second base substrate BS2 may be transmitted to the bonding layer SLM through the filter layer FYb, and light in a local wavelength range of external light incident through the second base substrate BS2 may be absorbed by the filter layer FYb and the second light shielding portion BP2b.
